To requiring, hydraulic oil No leakage, loop is enough to ensure that the synchronous raising and lowering of two lift arms.But, firstly, since hydraulic cylinder
In the presence of certain foozle, two hydraulic cylinders can not possibly be just the same；Secondly, there is natural wearing in two oil cylinder hydraulic oil；The
Three, can all be produced because leakage is inevitable, such as at the pipeline connection between two oil cylinders, between oil cylinder and piston etc. certain
Leakage, and as the increase of cylinder efficient pressure, use time extend, leakage will be more serious.For these reasons, two-piston
Vector shift error must be produced.Over time, displacement error constantly adds up.When cumulative errors permit beyond two lift arms
Perhaps height, synchronism will distortion.This synchronous error, with the raising of level of processing, foozle can be ignored；
Error is mainly what is caused by hydraulic fluid leak and natural wearing.In order that two lift arms can run simultaneously for a long time, it is necessary to
This synchronous error is eliminated, that is, introduces oil-supplementing system.
