What are the main factors of pollutants in hydraulic system of aerial work platform?
The hydraulic system is an important part of the aerial work platform. The walking of the aerial work platform depends on the hydraulic motor, the driving action depends on the hydraulic pump, and the execution action depends on the hydraulic cylinder, so the hydraulic system is the life of the aerial work platform! If the hydraulic system is polluted, it will seriously affect the reliability and service life of the aerial platform.
In the process of manufacturing, assembling and debugging, the main pollutant of hydraulic system is assembly pollutant. The harm degree of these two kinds of pollutants is mainly due to the anti pollution design of the system, the cleanliness level of the products when they leave the factory, the working environment and daily maintenance.
Pollution particles harm the hydraulic system. Each pollution particle is a "corrosive seed". It spreads throughout the whole system with the flow of hydraulic oil. When it passes through the actuator of pump and valve, it will aggravate the wear of friction pair. New pollution particles are produced, resulting in a vicious circle, which seriously threatens the normal operation of the hydraulic system
Make. When the dirt particles enter into the gap between the movements, it will scratch the surface, intensify the wear, expand the gap, or block the throttle hole and damping hole, cause vibration or action failure, or even make the valve core stuck. If dirt particles get stuck in the outrigger cylinder
If the lock fails, it will cause a rollover accident.
