Structure and design of hydraulic system for mobile crushing station

In recent years, with the rapid development of domestic modernization, the rapid development of construction projects, such as buildings, highways, bridges and other construction projects in the city, has been developed, and a large number of construction wastes are also produced. How to deal with these wastes and how to recycle these wastes has become a problem to be solved urgently. It can be used in time to smash these wastes and use it as building material two times in time, which has greatly promoted the rapid development of the mobile crushing station technology.
Structure and working principle of hydraulic system of mobile crushing station
The whole hydraulic system consists of the following parts: the hydraulic pump driven crushing mechanism supporting system, the crawler walking chassis support system, the conveying support system (vibration feeder, main conveyer belt conveyor, auxiliary conveyer belt conveyor, iron remover), hydraulic cylinder driven supporting system, hydraulic pump driving oil cooling system and auxiliary branch system Unification.
The working mechanism of mobile crushing station alternates with other institutions. Its hydraulic system control principle is:
1. Moving the crushing station, the displacement of the closed variable pump of the broken mechanism is adjusted to zero, and it stops working. The vibration feeder, the main conveyer belt conveyor, the auxiliary conveyer, the iron remover, the load sensing valve of the hydraulic cylinder are in the middle function, and the oil supply is stopped.
2, the mobile crushing station stops walking. When the rest of the organization works, the load sensing valve piece of the walking mechanism is in the middle position and stops supplying oil to the system.

Design of hydraulic control system for mobile crushing station
The design of the full hydraulic mobile crushing station adopts the modular design method, which is mainly divided into the starting module, the system initialization module, the starting / maintenance module, the breakup / walking module, the automatic / manual module and the technical module. Automatic modules include automatic start mode and automatic stop mode; manual modules include manual start mode, manual stop mode, crawler walking mode, setting and maintenance mode.
1. Under the automatic start mode, the controller automatically completes the start operation of the iron remover, the main and vice belt conveyor, the crusher and the miner, as well as the telescopic operation of the hydraulic cylinders, and sends the feedback information to the human-computer interface in the automatic starting process.
2. Under the automatic stop mode, the controller automatically completes the stop operation of the iron remover, the main auxiliary belt conveyor, the crusher and the miner, as well as the telescopic operation of the hydraulic cylinders, and sends the feedback information to the man-machine interface in the automatic stop process.
3. Under the walking mode, the controller performs the crawler walking instruction according to the man-machine interface, and completes the operation of the left track and back, the right track and back.
Red Star machine manufacturers introduce advanced technology abroad to transform the hydraulic system of mobile crushing station, which has high reliability, good stability, strong anti-interference ability, can adapt to bad working conditions, and can create greater value at smaller cost. Henan Hongxing Mining Machinery Co., Ltd. is the largest R & D and production base of mining equipment in China. The mobile crushing station is our company’s signboard equipment.
