side when handling (compression) garbage truck hydraulic system fault diagnosis and treatment of:

when the hydraulic system is not working properly. you should first check the PTO engages, adequacy of hydraulic oil tank, suction pipe ball valve is completely open.

1, hydraulic systems without action, follow these steps according to this check. 

a, oil in the hydraulic oil tank is adequate. insufficient hydraulic oil should raise;  

b, observed the tank to pump into the tubing is flat h aspiration due to aging. If this behavior should replace tubing. 

c, check the gear oil pump failure. fitted with pressure gauges, screwing the regulator bolts to observe table regulation;  

d, such as regulating bolt after screwing in all is still not up to the required pressure, it is gear oil pump failure, shall replace the gear oil pump;

e, such as gear oil pump as normal, is a multi-way valve clogged. should remove the valve core to remove impurities, replace into for later use. 

2, hydraulic body motion, but are unable to check gear oil pump failure, the system pressure is within regulation. 

3, hydraulic body motion slows down  

check gear oil pump failure, oil oil filter, oil return oil filter core is blocked.
