Why Is There A Concrete Pump Drying Phenomenon?

Cut-out for vertical, especially to the 50 m height above the commodity concrete pump sending harm is obvious.

cause analysis:

This product concrete pump pump for the whole pilot concrete ready-mixed concrete, ready-mixed concrete and constant power main oil pump through the hydraulic valve 8-1, 8-2, 10-1, 10-2 to the master cylinder and the cylinder 9 for dispensing valve oil. Master cylinder cartridge valve and dispensing valve cylinder hydraulic control signals, respectively, reversing valve, the main fuel tank and dispensing valve cylinder action sequence coordination to achieve concrete ready-mixed concrete delivery pumping cycle, wherein the master cylinder 10-cylinder alternately suck - continuous row of concrete realization of concrete batch plant delivery pumping. It appears to change every concrete process flow stream usually obvious - off - flow phenomenon, known as stop the phenomenon.

For most of the concrete boom pump system, through the adoption of electric proportional control of constant power concrete pump plunger items to solve the problem of cutoff.Because the electric proportional control of constant power control + is electronically controlled variable prior to the constant power control, just below the power hyperbolic emissions are controlled by the adjustment, the current in the reversing process and after reversing cylinder piston push pipe concrete before exercise, in the system pressure is usually lower than commodity concrete pump pressure, can increase the main oil commodity concrete pump displacement was adopted to realize rapid reversing distributing valve, reduce the reversing to began to promote the concrete time, realizing the concrete flow from the apparent.
