- Abstract:
- In allusion to the self-lock failure mode existing in the development of a certain piston pump, the operating sequential table and state K-map of the pump’s pneumatic control circuit are built with the fluid logic theory. The logic behaviour of the pneumatic control circuit is analyzed by logical deduction. The analysis results indicate that the self-lock failure will happen when two slide valve position state are the same. The reason why the self-lock failure occurs in two slide valve control mode is demonstrated in theory. Then a method to control the pump by single slide valve is put forward and it can avoid logical hazard.
