1. The concrete pump degree of symmetry error caused by the connecting rod and the boom and the hydraulic cylinder friction. Check the boom, the contact area between the cylinder, hydraulic cylinder, if wear serious, need repair or replacement,

2. concrete pump Tire symmetry error hydraulic cylinder block with the arm frame is too big, causing friction. Check the tires and boom of the interface, if wear serious need repair or replacement; Pay attention to the specification when the choice, and make clear direction of rotation, to prevent water leakage accident, the installation of a leakage protection switch is recommended. Note when installation cable overhead, the power cord is not too long. Don’t let the cable force during unit water, lest cause the power cord rupture. Lubrication is not good.

Can check the sound of the concrete pump lubrication condition; Then there is the motor insulation resistance is lower than 0.5 M ∏; 13 kw motor can be directly below the start, 13 kw or start the compensator should be adopted. Try to avoid boot when low pressure, do not frequently switch motor. Immediately halt this is because the pump will produce reflux, if boot, can make the motor load startup, led to the start current is too large and burn out. Don’t let the noise of the cement foaming machine overload operation for a long time, don’t smoke sediment concentration of water, electric pump dehydration running time shoulds not be too long. Check motor more at ordinary times.
