Pipe pushing jack mud control system

Abstract

The invention discloses a pipe pushing jack mud control system, belonging to the technical field of trenchless machinery. The system comprises a control module for controlling a mud sending motor anda mud discharging motor, and a bypass valve and an internal circulating valve both mounted in a pipe pushing jack mud system, the control module is in control connection with a first solenoid valve and a second solenoid valve; the first solenoid valve is in control connection with the bypass valve, and the second solenoid valve is in control connection with the internal circulating valve; and thecontrol module is electrically connected with a pressure sensor for detecting pressure in the pipe pushing jack mud system, and a proximity switch for detecting whether the bypass valve and the internal circulating valve are opened or closed in place. The pipe pushing jack mud control system provided by the invention, according to different construction geologies, can adjust a system pressure value through a man-machine display interface, properly adjust preset pressure P1 and realize automatic control of the mud system under different pressure and different flow states, and has the advantagesof reducing pipe flushing time, improving construction efficiency, reducing construction difficulty and improving automation degree.

Description

technical field [0001] The invention relates to the technical field of trenchless machinery, in particular to a mud control system for a pipe jacking machine. Background technique [0002] Due to the complex working conditions in the construction process of the pipe jacking machine, hard rock formations, soft soil formations, accumulation of muddy water cavity, blockage of mud discharge pipes, etc., the requirements for the operator's experience are relatively high, and experienced operators on the market Relatively scarce, resulting in slow construction progress and high mechanical failure rate. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides a mud control system for pipe jacking machines, so as to reduce the difficulty of equipment operation and improve equipment construction efficiency. [0004] The present invention is realized through the following technical solutions: a mud control system for a pipe j...
