Notes on replacement of piston and valve body of concrete pump truck

Notes for replacement of piston and valve body of concrete pump truck:

Frame pump car is one of the main components of the piston type, but also its main vulnerable parts, in the use of a certain number of cubic, it will need to be replaced, under normal circumstances, when the inner wall of the cylinder block scratches or wear, are taken out for maintenance, or the use of u-turn.

In order to facilitate the maintenance and replacement of the concrete cylinder, the mainstream equipment manufacturers will set a movable door cover at the bottom of the concrete hopper, the opening and closing of the movable door cover can be completed by moving the cylinder, at the same time, the concrete cylinder can also be pulled out from the opening part. After using this new structure, changed the past concrete cylinder replacement, need to use lifting equipment to lift it out for maintenance, greatly reduce the labor intensity.

In addition to replacing the piston mentioned above, the valve body is also one of the important parts that need to be checked and maintained regularly. As we all know, distribution valve components are not many, only a few main components. If the distribution valve components are damaged, in order to effectively improve the performance of the whole arm pump truck, a reasonable and simple way is to directly replace the distribution valve.

At present, there are three categories of distribution valve, respectively, are tubular swing valve, rotary plate valve and gate valve, rotary plate valve and gate valve application is less, and the swing valve is widely used, is the current mainstream of the market. Swing valve is mainly composed of S swing tube, cutting ring and glasses plate, the replacement process is relatively simple, as long as the maintenance procedures are strictly followed, the owner can complete the whole replacement process with the cooperation of technical personnel.
