Shantui SL50W-2 loader air boosting pump XZ60A-3510001

Improvement of Boosting Pump
There are two oil passage holes at the bottom of the oil cup, which respectively lead to the front end of the hydraulic cylinder piston and the middle oil chamber, so when the cylinder piston pushes the hydraulic cylinder piston to move forward, the two holes are connected with the central oil inlet chamber of the hydraulic cylinder piston due to The oil inlet chamber is filled with brake fluid before starting work, and there is no volume change in the oil inlet chamber during operation, so the piston of the hydraulic cylinder moves outside the two holes, and the brake fluid in the oil cup does not turn up and down. Therefore, no bubbles are generated.
When the piston of the hydraulic cylinder moves between the two holes, the volume of the oil chamber will change slightly, which will cause the oil surface in the oil cup to move slightly. At the same time, the oil cup is changed into a sealing structure to prevent dust in the air from entering the oil, effectively Maintains the cleanliness of the brake fluid
