TYA100 hydraulic oil vacuum oil purifier handles the fault of the loader oil station

　　TYA100 hydraulic oil vacuum oil purifier to deal with the faults of the loader oil station. This series of oil filters is suitable for unqualified hydraulic oil, lubricating oil, gasoline engine oil, diesel engine oil, compressor oil in the oil field, mining, metallurgy, electric power, transportation, manufacturing and other industries. , Gear oil, cutting oil, heat treatment oil, refrigerating machine oil, anti-wear hydraulic oil and other high-precision industrial lubricating oil regeneration treatment.

　　This machine can quickly remove water, gas, impurities and volatiles (motor oil, gasoline, diesel, kerosene, etc.) in the oil. Improve oil quality, restore lubricating oil viscosity, flash point and performance. Ensure the normal operation of hydraulic system, power system and lubrication system.

　　TYA100 hydraulic oil vacuum oil purifier diagnosis analysis:

　　If the boom is only weak to lift and the bucket does not drop when turning, the working gear pump does not need to be checked. The fault occurs in the working part of the boom lever of the work distribution valve or the piston oil seal in the boom hydraulic cylinder is damaged, causing internal leakage. Due to.

　　If the bucket flips and the boom is weak at the same time, the fault is usually the work gear pump is severely burned or the oil leaks, or the adjustment valve of the work distribution valve is not "closed", or the pressure is adjusted improperly, or the adjustment spring is damaged.

　　Method of exclusion:

　　Replace the piston oil seal of the hydraulic cylinder, check whether the matching gap between the boom valve stem and the valve body exceeds 0.035mm, and replace the work distribution valve if necessary.

　　Check whether the working gear pump is burnt, mainly check whether the skeleton oil seal on the drive shaft of the working gear pump is damaged. Check whether the pressure regulating valve of the work distribution valve is damaged, and replace the damaged parts if necessary.

　　The working gear pump of B2 working device bursts and leaks oil

　　Diagnostic analysis:

　　The pressure regulating valve or overflow valve in the work distribution valve is stuck, which makes the system oil circuit in a closed state, and the system pressure increases infinitely, which then causes the gear pump body to burst. Or the operator did not operate according to the maintenance requirements and adjusted the pressure without authorization to make the system pressure exceed the specified value, which would easily cause the pump body to burst.

　　Due to the long-term high pressure inside the working gear pump, the connecting bolts of the front and rear pump covers and the pump body are stretched and elongated, causing loosening and oil leakage, or radial cracks in the pump cover and pump body, between the pump cover and the pump body of. Damaged ring seals can also cause oil leakage.

　　Method of exclusion

　　The pressure regulating valve of the work distribution valve is often removed and washed to ensure that the pressure regulating valve works normally and moves flexibly. This kind of adjustment method can be used to turn the pressure regulating bolt of the pressure regulating valve one week, and the system pressure can be increased by 3.0~4.0MPa, and vice versa, it can be reduced by 3.0~4.0MPa.

　　Every 0. Regularly check whether the connecting bolts between the pump cover and the pump body of the gear pump are loose. Sometimes, the bolts cannot be tightened due to the shallow depth of the bolt holes. At this time, shorten the bolts accordingly. In addition, the pressure relief grooves on both sides of the gear pump should be installed in the high-pressure cavity of the gear to prevent the gear pump from "trapping oil" and causing the gear pump to explode. The bucket hydraulic cylinder of the working device has the phenomenon of "cylinder pulling", the tie rod is bent and deformed, the pin joint bearing of the bucket hydraulic cylinder is broken, and the locking nut of the piston of the bucket hydraulic cylinder is pulled "out of teeth".

　　Diagnostic analysis:

　　When the boom is raised to a certain height and the bucket is in the limit position of downward turning, the outer extension of the piston rod of the bucket hydraulic cylinder is short, and the limit point of the boom is in contact with the bottom surface of the bucket. If you continue to raise the boom, the shovel will It is impossible for the bucket to flip down as the boom continues to lift. The relative positions of the hinge points at both ends of the bucket hydraulic cylinder and the central hinge point of the rocker arm will change as the boom continues to lift (that is, mechanical interference occurs). This forces the piston rod of the bucket hydraulic cylinder to pull out. As the front and rear chambers of the cylinder are in a closed state during the boom lifting process, the external pulling of the piston rod will inevitably cause the pressure in the front chamber to increase sharply. Open the one-way relief valve to the rear chamber, and the hydraulic oil will flow from the front chamber to the rear chamber. , The pressure in the front cavity drops immediately, and the piston rod extends outward, which is the phenomenon of "cylinder pulling".

　　It can be seen from the fault phenomenon that if the one-way valve in the piston "stucks" (cannot open), when the boom rises, the front cavity of the bucket hydraulic cylinder will produce "oil trapped" due to movement interference, and the pull rod will be greatly pulled. , The joint bearing at the pin shaft is affected by the pulling force, if the interference is serious, the joint bearing will be broken.
