Principle Analysis of Pipe Blocking in Wet Spraying Machine

How to solve the pipe blockage fault of wet spraying machine? Saner Heavy Industry through analysiswet spraying machine,Wet spray trolleyThe whole process of power transmission and material transportation in the injection process points out the key points to improve the problem, and puts forward the improvement measures and inspection standards of the product.

Compared with dry spraying, wet spraying technology has the advantages of high efficiency, labor and material saving, and pollution reduction. The application of wet spraying machine in tunnel construction is becoming more and more common. Pipe blocking is one of the main faults in the operation of wet spraying trolley. How to solve the pipe blockage failure, control the product quality and reduce the subsequent product blockage failure rate is an important issue facing the construction of wet spraying machine.

Many scholars and constructors have studied and summarized the pipe blocking of wet spraying machine, some from the mesoscopic theory analysis, some from the point of failure to describe and propose solutions, but the lack of systematic summary. Saner Heavy Industry believes that the essence of wet spraying machine operation in the process of power transmission and material transportation is to add a certain amount of kinetic energy to the concrete, overcome various resistances and the quality of the concrete itself, and attach it to the excavation surface. The whole operation includes the whole process from the generation of power to the termination on the excavation surface, and the whole process from the unloading of concrete from the tank truck to the termination on the excavation surface.

After the motor runs normally, the system is supplied with pressure. The hydraulic pressure drives the hydraulic cylinder to reciprocate. The hydraulic cylinder and the concrete cylinder are connected through transition parts to drive the concrete cylinder piston to move (suction and discharge). The S pipe is always connected with the discharge concrete cylinder port through the swing cylinder switching. After that, the material enters the outlet flange, hard pipe, hose and mixer until it is ejected from the nozzle. This is the whole process of power transmission. After the concrete is poured out from the tank car, it first passes through the screen, then is sucked into the hopper by the concrete cylinder, then is punched out by the concrete cylinder to the S pipe, through the outlet flange to the hard pipe, then to the hose and the mixer, and finally is sprayed out from the nozzle, which is the whole process of material transportation.

wet spraying machineThe operation process is composed of various factors connected in series, so there are many factors that cause pipe blockage of wet spraying machine and wet spraying trolley. The problem is a systematic problem, and minor faults in each link will be accumulated into the result in proportion to a certain weight. The spray volume of the Saner heavy industry wet spray machine is adjustable, the accessories have a long service life, and the mixture of the atomized jet and the nozzle material makes the accelerator and the concrete mix evenly. Using wet spray technology,Wet spray trolleyThe rebound rate can even be reduced to less than 10%, effectively saving costs.
