Abstract

The invention discloses a mud control system for a pipe jacking machine, which belongs to the technical field of trenchless machinery. It includes a control module for controlling the mud feeding motor and the mud discharging motor, and a bypass valve and an internal circulation valve installed in the mud system of the pipe jacking machine. The control module is connected with solenoid valve 1 and solenoid valve 2; The control of solenoid valve one is connected to the bypass valve, and the control of solenoid valve two is connected to the internal circulation valve; the control module is electrically connected to a pressure sensor for detecting the pressure in the mud system of the pipe jacking machine, and is used to detect whether the bypass valve and the internal circulation valve are open. Proximity switch in place. According to different construction geology, the present invention can adjust the system pressure value through the man-machine display interface, adjust the preset pressure P1 appropriately, realize the automatic control of the mud system under different pressures and different flow states, reduce the pipeline flushing time, and improve the construction efficiency. The advantages of reducing the difficulty of construction and improving the degree of automation.

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...
