WB400 type built-in stabilized soil mixer machine rotor fault does not work

A WB400 type central stabilized soil mixing machine turns over, and in the process of use, the rotor of a milling mixing rotor stops rotating immediately after loading. By the analysis of the causes of failure may be:

(1) the level of oil is too low, resulting in pump oil supply shortage, the operating oil pressure is reduced, unable to complete the process control system; oil deterioration, loss of lubrication effect and make the control valve spool stuck, swash plate pump which is always in a.

(2) controlling the fracture of flexible shaft. This phenomenon is difficult to see from the appearance, in this regard, one person can operate the pump handle on the instrument console, the other person to observe the displacement of the work pump handle, to see whether it rotates.

(3) the working pressure of the pump is not normal, the entire system will not work.

(4) the filter clogging of the oil inlet of the oil pump, resulting in insufficient oil supply of the pump, reduced the pressure of the control oil, unable to complete the control process of the system.

(5) the bypass valve is in the open position, so that the system pressure can not be raised, and the working motor can not work.

(6) system pressure limiter and high pressure safety valve fail, so that the system pressure can not be established, resulting in the work motor can not work properly.

(7) the failure of the pump displacement control device. If the displacement of the working pump controls the fracture of the connecting rod mechanism (manual displacement control) or the oil inlet one-way throttling hole, the swash plate of the pump will always be in the position of zero displacement because of no control.

(8) pump up the disorder, lead to insufficient fuel.
