What Is The Reason For The Disordered Operation Of The Hydraulic Cylinder Of The Tunnel Mucking Machine?
How does the mining Tunnel Mucking Machine deal with the problem of disordered operation of the hydraulic cylinder of the slag scraper? In order to improve the work efficiency, the lifting handle of the distribution valve of the crawler mucking loader is lifted at the same time, so that the rise and forward tilt of the load form a compound motion, but sometimes confusion occurs.
1. Convert the pressure signal of the small crawler mucking loader to an electrical signal, and then convert the electrical signal into an on-off signal of the oil circuit, which is another ideal solution to avoid the phenomenon that the lifting cylinder does not rise but falls. 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 slag scraper, so that the component circuits are connected in an appropriate way. When the lifting cylinder rises, if the pressure rises to a certain value, the pressure relay will send 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 it will not descend.
2. mini mucking loader Liquid flow direction control, connecting a one-way valve in series in the branch oil circuit of the lifting cylinder is the most simple and effective method to avoid the movement disorder of the hydraulic cylinder. When the pressure of the lift cylinder is too large during the rise, the check valve can effectively prevent the backflow of the oil by virtue of its characteristic of restricting the flow of oil, so that the lift cylinder will only decelerate and stop during the rising movement, and will not descend. Of course, the one-way valve can only achieve the desired effect if it is installed on the oil inlet before the lift reversing valve.
