How to deal with oil leakage in hydraulic lathes?

1. Dredging method to ensure that the oil of the hydraulic lathe can be unblocked normally. On the oil return channel, once there are small holes, the structure is unreasonable, and there is dirt blockage, it should be adjusted in time to ensure that the oil return can be unblocked normally and the groove pipeline can be unblocked, which can reduce the leakage of lubricating oil.

2. Plugging method, in the sand hole of the hydraulic lathe, the part of the casting can be blocked to prevent leakage.

3. Adjustment method, the hydraulic lathe needs to adjust the oil pressure of the hydraulic lubrication system to reduce the pressure of the system, adjust the sliding bearing of the hydraulic lathe, and only reduce the distance between the bearing hole and the journal for the ordinary size, reduce the flow of the equipment, and avoid leakage caused by excessive overflow.

4. Transformation method, in the process of leakage control of hydraulic lathe, sometimes it is necessary to improve the sealing material, change the fastening method, change the lubricating medium, reform the oil return position, improve the leakage prevention measures, etc. in order to eliminate the leakage phenomenon of the equipment, especially when the hydraulic system increases the oil return groove, expands the screw hole, and adds the oil connection pan, ordinary lathes should pay special attention to this problem.

5. Repair method, the hydraulic lubrication control system has burrs, strains, deformations, etc., resulting in external or internal oil leakage, it is necessary to repair and prevent leakage.

6. Replacement method, when the seal is worn, damaged and cannot be repaired, the main replacement parts are needed to maintain the matching relationship.

The hydraulic press will leak oil from time to time during use, Zhengzhou Yellow River Machinery Company.

Oil leakage in the hydraulic system is mainly caused by the pressure difference between the liquid in the hydraulic components and pipelines and the leakage caused by the gap between the components, once the leakage of the hydraulic system occurs, the system pressure can not be established, and the leakage of hydraulic oil will also cause environmental pollution, affect production and even produce incalculable serious consequences.

There are two main kinds of leakage in the hydraulic system of engineering hydraulic machinery, the leakage of the fixed seal and the leakage of the moving seal, the leakage of the fixed seal mainly includes the bottom of the cylinder, the connection of each pipe joint, etc., and the moving seal mainly includes the piston rod of the cylinder, the stem of the multi-way valve and other parts. The external leakage mainly refers to the leakage of hydraulic oil from the system to the environment, and the internal leakage refers to the existence of the pressure difference between the high and low pressure sides and the failure of the seals, so that the hydraulic oil flows from the high pressure side to the low pressure side in the system.

The reliability of the hydraulic system depends to a large extent on the design of the seal of the hydraulic system and the selection of the seal, due to the unreasonable selection of the sealing structure in the design, the selection of the seal does not conform to the specification, and the compatible type, load situation, ultimate pressure, working speed, and environmental temperature change of hydraulic oil and sealing material are not considered in the design. These are all directly or indirectly causing leaks in the hydraulic system to varying degrees. In addition, due to the dust and impurities in the use environment of construction machinery, a suitable dust-proof seal should be selected in the design to avoid dust and other dirt from entering the system to destroy the seal and pollute the oil, resulting in leakage.

If it is oil leakage at the superimposed valve (cartridge valve), check whether it is because the seal of the valve fails and leaks, if it is to replace the seal; If it is due to the cracking of the valve block, it is generally caused by the material of the valve block, or the external force, there is no good way to do this (including the thread damage of the valve block), and generally only a new valve block can be replaced.

The hydraulic oil leakage of the car is serious. Hydraulic cylinders.

If the oil leak is not treated, it will pollute the environment, and the hydraulic oil in the oil tank will be reduced, resulting in economic losses. If the cause of the oil leak is not found, the oil leakage will become more and more serious, and eventually affect the use. If it is near the high temperature of the steelmaking furnace of the steel mill, Pizhiduan will also cause an accident, so the oil leakage of the cylinder should be dealt with as soon as possible.

Automotive hydraulic fluids

Hydraulic oil is a hydraulic system that uses the pressure energy of liquid.

The hydraulic medium used plays the role of energy transfer, anti-wear, system lubrication, anti-corrosion, anti-rust, cooling and so on in the hydraulic system.

Hydraulic fluids should have the right viscosity and good viscosity and temperature properties. Excellent lubricating properties (anti-wear properties). Excellent thermal and oxidative stability, hydrolysis stability, and shear stability.

Good demulsibility. Good anti-rust and corrosion resistance. Good foam resistance and air release.

Good adaptability to sealing materials. Excellent reputation for cleanliness and filtration.

Fellow, I really didn't understand, I can be more specific.

The reasons for the occurrence of hydraulic oil leakage may be damage to the hydraulic oil line, loose hydraulic oil line joints, damage to the hydraulic oil pump, blockage of the hydraulic oil filter, damage to the hydraulic oil tank, etc. Workaround:1

Check the hydraulic oil line, check whether the hydraulic oil line is damaged, whether the joint is loose, if there is damage, it should be replaced in time. 2.Check the hydraulic oil pump, check whether the hydraulic oil pump is damaged, if there is damage, it should be replaced in time.

3.Check the hydraulic oil filter, check whether the hydraulic oil filter is blocked, if there is a blockage, it should be cleaned or replaced in time. 4.

Check the hydraulic oil tank, check whether the hydraulic oil tank is damaged, if there is damage, it should be replaced in time. Personal Tips:1

When using CNC machine tools, the hydraulic oil pipeline, hydraulic oil pump, hydraulic oil filter and hydraulic oil ballast box should be checked regularly, and the problem should be found and dealt with in time. 2.When using CNC machine tools, the hydraulic oil should be replaced regularly to ensure the quality of the hydraulic oil so as not to damage the machine tool.

3.When using CNC machine tools, you should pay attention to the temperature of the hydraulic oil, if the temperature is too high, you should take measures to reduce the temperature in time to avoid damage to the machine tool.

Oil leakage from engine respirator is also often referred to as, exhaust pipe dripping oil, oil leakage, large exhaust gas, lower exhaust channeling, lower exhaust dripping oil, etc.

A respirator is a one-way valve. When the crankcase has exhaust pressure, it opens and discharges the exhaust gas outward. When there is no pressure, it closes to keep the crankcase under negative pressure, and the oil is not easy to leak, and the oil will not be discharged into the cylinder liner.

When the diesel engine is working, there will be a small amount of high temperature and high pressure gas from the piston ring group and the cylinder wall, the valve stem and the valve guide and the supercharger bearing into the crankcase, the blow-by gas will dilute the oil, and at the same time will increase the air pressure in the crankcase, reduce the power output of the diesel engine, and damage the sealing performance. The oil-air separator is mainly used to maintain the pressure balance between the inside of the crankcase and the outside of the body when the diesel engine is working, and at the same time separate the oil in the mixed exhaust gas in the first box, discharge the exhaust gas, reduce the oil leakage of the diesel engine and reduce the corrosion of parts, and improve the economy of the diesel engine. However, if the design and layout of the oil-gas separator is not reasonable, the separation system will not play the role of separating oil and gas, but will lead to undesirable phenomena such as oil channeling in the diesel engine.

Oil leakage or large amount of oil dripping from the vehicle's engine respirator (lower exhaust) is mainly caused by poor valve sealing or serious wear of the four matches.

It is normal for a small part of oil to stick to the exhaust pipe in winter, mainly because the temperature in the crankcase is much higher than the outside temperature, so when the hot gas in the crankcase reaches the exhaust pipe, due to the difference between the internal and external temperature, the oil will be formed, so there is oil in the exhaust pipe.

Solution: Please drive the vehicle to the service station for maintenance as soon as possible, while driving, you must pay attention to the change in the amount of exhaust oil leakage under the vehicle, and when there is a pressure indicator alarm, you should replenish the oil in time or contact the service station directly.

1.Pay attention to the oil bai, check the filter element frequently, and change the du for 2Let's see if there is an unreasonable dao design

The place back, the place that should be poured into the corner of the garden is not upside down.

3.Always check the seals for oil leakage, and don't wait until they leak before replacing them.

4.If it is a cylinder piston rod or something, pay attention to whether there is any abnormal sound, whether there are traces of scratching on the surface of the piston rod, if there may be dirt inside, iron filings or something, it will scratch the seal and pay attention to cleaning and maintenance.

The key is to make a fuss about the seal.

According to different sports, different structures, different environments, there are different practices.

You need to check it out in the professional forums.

I feel that the upstairs are all about prevention, if the landlord urgently needs to solve the BAI oil leak.

This is a long-standing and difficult problem, regular maintenance, pay attention to the working environment, choose the appropriate hydraulic oil, reasonable system design, avoid high-frequency overload use can prolong the service life.
