Analysis and Solutions to Oil Pump Failures in Machining Centers
In the field of mechanical processing, the efficient and stable operation of machining centers plays a crucial role in production efficiency and product quality. As a key component of the lubrication system in machining centers, whether the oil pump operates normally directly affects the performance and lifespan of the machine tool. This article will conduct an in-depth exploration of the common failures of oil pumps in machining centers and their solutions, aiming to provide comprehensive and practical technical guidance for mechanical processing practitioners, helping them quickly diagnose and effectively solve oil pump failures when faced with them, and ensuring the continuous and stable operation of machining centers.
I. Analysis of Common Causes of Oil Pump Failures in Machining Centers
(A) Insufficient Oil Level in the Guide Rail Oil Pump
Insufficient oil level in the guide rail oil pump is one of the relatively common failure causes. When the oil level is too low, the oil pump cannot extract enough lubricating oil normally, resulting in the ineffective operation of the lubrication system. This may be due to the failure to check the oil level in time and replenish the guide rail oil during daily maintenance, or the oil level gradually decreases due to oil leakage.

(B) Damage to the Oil Pressure Valve of the Guide Rail Oil Pump
The oil pressure valve plays a key role in regulating oil pressure in the entire lubrication system. If the oil pressure valve is damaged, situations such as insufficient pressure or inability to regulate pressure normally may occur. For example, during long-term use, the valve core inside the oil pressure valve may lose its normal sealing and regulating functions due to reasons like wear and blockage by impurities, thus affecting the oil output pressure and flow rate of the guide rail oil pump.

(C) Damage to the Oil Circuit in the Machining Center
The oil circuit system in the machining center is relatively complex, including various oil pipes, oil manifolds and other components. During the long-term operation of the machine tool, the oil circuit may be damaged due to external impacts, vibrations, corrosion and other factors. For example, oil pipes may rupture or break, and oil manifolds may deform or become blocked, all of which will hinder the normal transportation of lubricating oil and lead to poor lubrication.

(D) Blockage of the Filter Screen in the Pump Core of the Guide Rail Oil Pump
The main function of the filter screen in the pump core is to filter impurities in the lubricating oil and prevent them from entering the inside of the oil pump and causing damage. However, with the increase in usage time, impurities such as metal chips and dust in the lubricating oil will gradually accumulate on the filter screen, resulting in blockage of the filter screen. Once the filter screen is blocked, the oil inlet resistance of the oil pump increases, the oil inlet volume decreases, and then affects the oil supply volume of the entire lubrication system.

(E) Exceeding the Standard of the Quality of the Guide Rail Oil Purchased by the Customer
Using guide rail oil that does not meet the requirements may also trigger oil pump failures. If indicators such as the viscosity and anti-wear performance of the guide rail oil do not meet the design requirements of the oil pump, problems such as increased wear of the oil pump and decreased sealing performance may occur. For example, if the viscosity of the guide rail oil is too high, it will increase the load on the oil pump, and if it is too low, an effective lubricating film cannot be formed, causing dry friction among the components of the oil pump during the working process and damaging the oil pump.

(F) Incorrect Setting of the Oiling Time of the Guide Rail Oil Pump
The oiling time of the guide rail oil pump in the machining center is usually set according to the working requirements and lubrication needs of the machine tool. If the oiling time is set too long or too short, it will affect the lubrication effect. A too-long oiling time may lead to waste of lubricating oil and even damage to oil pipes and other components due to excessive oil pressure; a too-short oiling time cannot provide enough lubricating oil, resulting in insufficient lubrication of components such as the machine tool guide rail and accelerating wear.

(G) The Circuit Breaker in the Electrical Box Trips Due to the Overload of the Cutting Oil Pump
During the working process of the cutting oil pump, if the load is too large and exceeds its rated power, it will lead to overload. At this time, the circuit breaker in the electrical box will automatically trip to protect the safety of the circuit and equipment. There may be various reasons for the overload of the cutting oil pump, such as the mechanical components inside the oil pump being stuck, the viscosity of the cutting fluid being too high, and faults in the oil pump motor.

(H) Air Leakage at the Joints of the Cutting Oil Pump
If the joints of the cutting oil pump are not tightly sealed, air leakage will occur. When air enters the oil pump system, it will disrupt the normal oil absorption and discharge processes of the oil pump, resulting in unstable flow rate of the cutting fluid and even the inability to transport the cutting fluid normally. Air leakage at the joints may be caused by reasons such as loose joints, aging or damage to seals.

(I) Damage to the One-way Valve of the Cutting Oil Pump
The one-way valve plays a role in controlling the unidirectional flow of the cutting fluid in the cutting oil pump. When the one-way valve is damaged, a situation where the cutting fluid flows backward may occur, affecting the normal operation of the oil pump. For example, the valve core of the one-way valve may not be able to close completely due to reasons such as wear and being stuck by impurities, resulting in the cutting fluid flowing back to the oil tank when the pump stops working, requiring the re-establishment of pressure when starting next time, reducing work efficiency and even possibly damaging the oil pump motor.

(J) Short Circuit in the Motor Coil of the Cutting Oil Pump
A short circuit in the motor coil is one of the relatively serious motor failures. When a short circuit occurs in the motor coil of the cutting oil pump, the motor current will increase sharply, causing the motor to heat up severely and even burn out. Reasons for the short circuit in the motor coil may include long-term overload operation of the motor, aging of insulating materials, moisture absorption, and external damage.

(K) Reverse Rotation Direction of the Motor of the Cutting Oil Pump
If the rotation direction of the motor of the cutting oil pump is opposite to the design requirements, the oil pump will not be able to operate normally and cannot extract the cutting fluid from the oil tank and transport it to the processing site. The reverse rotation direction of the motor may be caused by reasons such as incorrect wiring of the motor or faults in the control system.

II. Detailed Solutions to Oil Pump Failures in Machining Centers
(A) Solution to Insufficient Oil Level
When it is found that the oil level of the guide rail oil pump is insufficient, guide rail oil should be injected in a timely manner. Before injecting the oil, it is necessary to determine the specifications and models of the guide rail oil used by the machine tool to ensure that the added oil meets the requirements. At the same time, carefully check whether there are oil leakage points on the machine tool. If oil leakage is found, it should be repaired in time to prevent the oil from being lost again.

(B) Handling Measures for Damage to the Oil Pressure Valve
Check whether the oil pressure valve has insufficient pressure. Professional oil pressure detection tools can be used to measure the output pressure of the oil pressure valve and compare it with the design pressure requirements of the machine tool. If the pressure is insufficient, further check whether there are problems such as blockage by impurities or wear of the valve core inside the oil pressure valve. If it is determined that the oil pressure valve is damaged, a new oil pressure valve should be replaced in time, and the oil pressure should be re-debugged after replacement to ensure that it is within the normal range.

(C) Repair Strategies for Damaged Oil Circuits
In the case of damage to the oil circuit in the machining center, it is necessary to conduct a comprehensive inspection of the oil circuits of each axis. First, check whether there are phenomena such as rupture or breakage of oil pipes. If oil pipe damage is found, the oil pipes should be replaced according to their specifications and materials. Second, check whether the oil manifolds are unobstructed, whether there is deformation or blockage. For blocked oil manifolds, compressed air or special cleaning tools can be used for cleaning. If the oil manifolds are seriously damaged, new ones should be replaced. After repairing the oil circuit, a pressure test should be carried out to ensure that the lubricating oil can circulate smoothly in the oil circuit.

(D) Cleaning Steps for Blockage of the Filter Screen in the Pump Core
When cleaning the filter screen of the oil pump, first remove the oil pump from the machine tool and then carefully take out the filter screen. Soak the filter screen in a special cleaning agent and gently brush it with a soft brush to remove the impurities on the filter screen. After cleaning, rinse it with clean water and then dry it in the air or blow it dry with compressed air. When installing the filter screen, ensure that its installation position is correct and the seal is good to prevent impurities from entering the oil pump again.

(E) Solution to the Problem of the Quality of the Guide Rail Oil
If it is found that the quality of the guide rail oil purchased by the customer exceeds the standard, qualified guide rail oil that meets the requirements of the oil pump should be replaced immediately. When selecting guide rail oil, refer to the suggestions of the machine tool manufacturer and choose guide rail oil with appropriate viscosity, good anti-wear performance and antioxidant performance. At the same time, pay attention to the brand and quality reputation of the guide rail oil to ensure its stable and reliable quality.

(F) Adjustment Method for Incorrect Setting of the Oiling Time
When the oiling time of the guide rail oil pump is set incorrectly, it is necessary to reset the correct oiling time. First, understand the working characteristics and lubrication needs of the machine tool, and determine the appropriate oiling time interval and single oiling time according to factors such as the processing technology, the running speed of the machine tool, and the load. Then, enter the parameter setting interface of the machine tool control system, find the parameters related to the oiling time of the guide rail oil pump, and make modifications. After the modification is completed, conduct actual operation tests, observe the lubrication effect, and make fine adjustments according to the actual situation to ensure that the oiling time is set reasonably.

(G) Solution Steps for the Overload of the Cutting Oil Pump
In the case where the circuit breaker in the electrical box trips due to the overload of the cutting oil pump, first check whether there are mechanical components stuck in the cutting oil pump. For example, check whether the pump shaft can rotate freely and whether the impeller is stuck by foreign objects. If mechanical components are found to be stuck, clean the foreign objects in time, repair or replace the damaged components to make the pump rotate normally. At the same time, also check whether the viscosity of the cutting fluid is appropriate. If the viscosity of the cutting fluid is too high, it should be diluted or replaced appropriately. After eliminating mechanical failures and cutting fluid problems, reset the circuit breaker and restart the cutting oil pump to observe whether its running state is normal.

(H) Handling Method for Air Leakage at the Joints of the Cutting Oil Pump
For the problem of air leakage at the joints of the cutting oil pump, carefully look for the joints where air leaks. Check whether the joints are loose. If they are loose, use a wrench to tighten them. At the same time, check whether the seals are aged or damaged. If the seals are damaged, replace them with new ones in time. After reconnecting the joints, use soapy water or special leak detection tools to check whether there is still air leakage at the joints to ensure good sealing.

When a short circuit in the motor coil of the cutting oil pump is detected, the cutting oil pump motor should be replaced in time. Before replacing the motor, first cut off the power supply of the machine tool to ensure the safety of operations. Then, select and purchase a suitable new motor according to the model and specifications of the motor. When installing the new motor, pay attention to its installation position and wiring method to ensure that the motor is installed firmly and the wiring is correct. After installation, conduct debugging and trial operation of the motor, and check whether parameters such as the rotation direction, rotation speed, and current of the motor are normal.

If it is found that the rotation direction of the motor of the cutting oil pump is opposite, first check whether the wiring of the motor is correct. Check whether the connection of the power lines meets the requirements by referring to the motor wiring diagram. If there are errors, correct them in time. If the wiring is correct but the motor still rotates in the opposite direction, there may be a fault in the control system, and further inspection and debugging of the control system are required. After correcting the rotation direction of the motor, conduct an operation test of the cutting oil pump to ensure that it can operate normally.

III. Special Considerations and Operation Points of the Oiling System in Machining Centers
(A) Oil Injection Control of the Oil Circuit with Pressure-maintaining Pressure Components
For the oil circuit using pressure-maintaining pressure components, it is necessary to closely monitor the oil pressure gauge on the oil pump during oil injection. As the oiling time increases, the oil pressure will gradually rise, and the oil pressure should be controlled within the range of 200 – 250. If the oil pressure is too low, it may be caused by reasons such as blockage of the filter screen in the pump core, oil circuit leakage or failure of the oil pressure valve, and it is necessary to conduct 排查 and treatment according to the corresponding solutions mentioned above; if the oil pressure is too high, the oil pipe may bear excessive pressure and burst. At this time, it is necessary to check whether the oil pressure valve is working normally and adjust or replace it if necessary. The oil supply volume of this pressure-maintaining pressure component is determined by its own structure, and the amount of oil pumped at one time is related to the size of the pressure component rather than the oiling time. When the oil pressure reaches the standard, the pressure component will squeeze the oil out of the oil pipe to achieve lubrication of various components of the machine tool.

(B) Setting of the Oiling Time for the Oil Circuit of Non-pressure-maintaining Components
If the oil circuit of the machining center is not a pressure-maintaining pressure component, the oiling time needs to be set by oneself according to the specific situation of the machine tool. Generally speaking, the single oiling time can be set at about 15 seconds, and the oiling interval is between 30 and 40 minutes. However, if the machine tool has a hard rail structure, due to the relatively large friction coefficient of the hard rail and higher requirements for lubrication, the oiling interval should be appropriately shortened to about 20 – 30 minutes. If the oiling interval is too long, the plastic coating on the surface of the hard rail may be burned due to insufficient lubrication, affecting the accuracy and service life of the machine tool. When setting the oiling time and interval, factors such as the working environment and processing load of the machine tool should also be considered, and appropriate adjustments should be made according to the actual lubrication effect.

In conclusion, the normal operation of the oil pump in the machining center is crucial for the stable operation of the machine tool. Understanding the causes of common oil pump failures and their solutions, as well as mastering the special requirements and operation points of the oiling system in the machining center, can help mechanical processing practitioners handle oil pump failures in a timely and effective manner in daily production, ensure the efficient operation of the machining center, improve production efficiency and product quality, and reduce equipment maintenance costs and downtime. At the same time, regular maintenance of the oil pump and lubrication system in the machining center, such as checking the oil level, cleaning the filter screen, and replacing seals, is also an important measure to prevent oil pump failures. Through scientific management and maintenance, the machining center can always be in a good working state, providing powerful equipment support for the production and manufacturing of enterprises.
In actual work, when facing oil pump failures in the machining center, maintenance personnel should remain calm and conduct fault diagnosis and repair according to the principle of starting with the easy and then the difficult and gradually conducting investigations. Continuously accumulate experience, improve their own technical level and fault handling ability to cope with various complex oil pump failure situations. Only in this way can the machining center play its maximum effectiveness in the field of mechanical processing and create greater economic benefits for enterprises.
