The main components of the automatic pipeline derusting and sandblasting machine

Baiyao automatic pipelineRust removal sandblasting machineIt is composed of three parts: air compressor, sandblasting device, walking frame and control system. Air compressor is mainly to provide power source for sandblasting operation. Generally, the working pressure is maintained at 0.4~0.8MPa, and it can provide 10m/min compressed air. The compressed air is processed by cooling device and oil-water separator to ensure the dryness of compressed air. ,no fuel.

The sand blasting device of the automatic pipeline derusting sand blasting machine is composed of a sand storage tank, 2 vacuum pumps, a control system, a dust filtering system, 2 nozzles, a sand blasting pipe and a sand returning pipe. The sand storage tank can be loaded with 300kg of steel sand. When working, the steel sand flows into the nozzle from the two sand valves at the bottom of the sand storage tank. The sand valve can adjust the sand output according to the rust removal effect of the rust removal sandblasting machine. Under the action, the steel grit gains kinetic energy and forms a high-speed steel grit flow, which is sprayed on the surface of the pipe through the sandblasting pipe, thereby removing the dirt and rust on the surface of the pipe.

The walking frame of the automatic pipeline derusting and sandblasting machine is composed of a lifting frame, an outer frame mechanism, a rotating mechanism and a swinging mechanism. Among them, the outer frame mechanism plays a role of overall positioning and support, and the two outer frame mechanisms are connected by a rotating mechanism. The rotating mechanism is installed in the guide wheel groove of the outer frame mechanism, and the rotating mechanism can be rotated 240° around the central axis of the pipeline through the action of the driving motor on it, so as to realize the rust removal function of the automatic derusting sandblasting machine on the pipe surface . The swing mechanism is fixed on the guide rail of the rotating mechanism, and a sandblasting gun is installed on it. Driven by the swing motor, it can move axially along the guide rail to realize the sandblasting and rust removal function of the device.

The control system of the automatic pipeline derusting and sandblasting machine uses a programmable controller as the control core to drive the walking motor, the swing motor and the sandblasting machine to realize the coordinated work of the sandblasting machine and the walking mechanism. The control system has the functions of adjusting the hoop travel speed, the axial travel speed, the axial amplitude and the step amplitude. The parameters can be adjusted according to the requirements of different operations to obtain a satisfactory derusting effect. The working mode of the automatic pipeline derusting and sandblasting machine is divided into automatic mode and manual mode. In automatic mode, no manual intervention is required, and all work can be completed by one-key operation; in manual mode, manual intervention can be carried out on circular walking. It can flexibly respond to abnormal situations that may occur during construction.
