Concrete pump dispensing valve does not swing the reasons

Use concrete machinery and equipment is very wide, in the course, we will find concrete pump dispensing valve does not swing, and this will affect the normal use of concrete machinery and equipment, leading to the dispensing valve does not swing What are the reasons, Haomei summarize the following main several reasons:

1. The dispensing valve or wiring fault jog buttons fall off;

2. The electro-hydraulic valve solenoid coil stuck or burned;

3. The dispensing valve is jammed foreign body;

4. The pilot relief valve malfunction is not enough pressure to make the change;

5. The constant pressure pump failure, mainly the pressure to make the change;

6. The concrete material difference, downtime and long, reversing resistance, pendulum does not move;

7. S tube bearing serious wear resistance commutation large;

8. pumping level, the level of line too short.
