description

Check valves at both ends of the main cylinder of the concrete pump truck. In normal work, the oil circuit is closed and the one-way valve works. The oil circuit plays a damping and buffering role to reduce the impact force of the main oil cylinder piston on the bottom of the main oil cylinder block. When the piston head is replaced, the one-way valve does not work when the oil circuit is opened, so that the piston can be drawn back to the cleaning chamber to facilitate the replacement of the piston.
Why does the damage of the check valve of the main cylinder of the concrete pump cause the cylinder stroke to be shortened and pumping weak?
Generally, there are two reasons for the shorter main cylinder stroke:
a. The main cylinder leaks, and long-term operation will cause the stroke to become shorter. When the leak in the main cylinder is small, the preset pressure can be reached by holding the pressure (close the shut-off valve), so it is not possible to judge whether the seal of the master cylinder is damaged by holding the pressure.
b. There are 4 one-way valves in a set of equipment. Generally, one-way valve on the rod cavity plays a role of oil supplement. When the one-way valve on the rod cavity is damaged (such as normal wear and tear, the spool cannot be opened smoothly), When the piston of the cylinder pushes forward by one cylinder and retreats, the retraction cylinder must be refilled through the rod cavity check valve of the extension cylinder to ensure that the retraction cylinder can be retracted to the bottom, because when the cylinder is retracted, when the piston runs to “U” In the area of ​​the ”-shaped tube, the oil in the rod cavity is returned to the main hydraulic system through the rodless cavity check valve (this check valve has the function of cooling the oil and buffering the piston), and it must be extended by The rod cavity check valve replenishes the retreat cylinder, otherwise the cylinder cannot return to the specified position. Long-term operation will cause the stroke of the master cylinder to become shorter. If the stroke becomes shorter, the piston rod of the cylinder is generally reset to fully extended by squeezing the pressure If the travel problem still occurs after a short period of time (a few hours), generally replace the one-way valve first (short replacement time, fast speed), if it still does not work, replace the master cylinder seal, but it is more time-consuming and necessary if necessary A set of work clothes.
