Lift can not rise or rise slowly, how to solve such problems, the following Wanxin drive to introduce you:
The above problems may occur because the relief valve pressure regulation does not meet the requirements; the internal leakage of the cylinder; the reversing valve is jammed or leaked inside; the oil level is too low and the oil filter is blocked;
There is a problem with the oil pump and other parts, and it is only necessary to solve the problem by solving the problem. Adjust the pressure to the required value; check or replace the cylinder assembly; check or replace the valve assembly; add enough oil to clean the oil filter; check or replace the pump to be hungry to solve the above problem. Second, ripper can not rise or fall or rise slowly from the place: overflow valve pressure regulation does not meet the requirements; oil tank leak; oil level is too low, the oil filter blockage; check valve leakage and other issues; can be adjusted The pressure reaches the required value; the directional valve locks or leaks; the check valve spring is fatigued, deformed, etc. The operating rod is heavy.
In addition to these common problems, there are problems with screw torque converters and faulty compensation systems, such as torque converter torque failure or power shift failure. We need to determine whether the reduction in production is caused by insufficient hydraulic fluid, improper pressure regulation, or insufficient back pressure.
When using the screw lift, it needs regular maintenance and maintenance to extend the life of the screw lift. During maintenance, the staff is required to control the accidental landing of the lift and cause the accident.
The monthly maintenance mainly checks the lubrication and wear conditions of the roller, intermediate shaft and bearing, cylinder pin and bearing, boom hinge shaft and bearing, prolongs the life span of the bearing, and also needs to check the hydraulic oil level and oil level. .
Mid-year maintenance is mainly to check the hydraulic and pipe joints, whether there is damage, whether the interface is loose; remove and disassemble the drop valve, use the compressed air to blow the dust and other debris of the valve core and reinstall; clean the fuel tank, empty the oil Wash and refill with oil.
