What Is The Cause Of The Deranged Operation Of The Hydraulic Cylinder Of The Mucking Machine
1. Converting the pressure signal of the pressure rise of the small mucking machine into electrical signal, and then converting the electrical signal into the oil circuit on-off signal is another ideal solution to avoid the phenomenon of the lifting cylinder not rising but falling. A two dimensional normally open solenoid valve and a pressure relay are connected in series in the oil circuit of the lifting cylinder of the mucking machine so that the component circuit is connected in a proper way. When the lifting cylinder rises, if the pressure rises to a certain value, the pressure relay will send out an electrical signal to energize the solenoid valve, and the oil circuit leading to the lifting cylinder will be quickly cut off, so that the movement of the lifting cylinder will stop, but will not fall.

2. Liquid flow direction control, connecting a check valve in series in the lifting cylinder branch oil circuit, is the most simple and effective way to avoid the movement disorder of hydraulic cylinder. When the pressure of the lifting cylinder is too large in the rising, the check valve can effectively prevent the backflow of oil by relying on its characteristic of restricting the oil flow, so that the lifting cylinder will only slow down and stop in the rising movement, and will not fall. Of course, only when the check valve is installed on the oil inlet road before the lift reversing valve can the ideal effect be achieved.
Three, in the oil circuit series of check valve is attached with the advantage that in the normal rise of the lifting cylinder of the tunnel mucking machine in case of sudden engine flout or sudden failure of the hydraulic pump, the check valve can avoid the lifting cylinder due to the loss of hydraulic pump oil source under the action of gravity load drop phenomenon.
