Peristaltic pump for tunnel construction, which consists mainly of pump house, rotor, roller, idle roller, squeese tube and driving unit. The squeeze hose is U-shape in pump house, when rotor drives rolles to rotate, hose is deformed. After the roller rotate, the deformed hose recover by its elasticity. Thus the negative pressure in this hose is generated, sucking slurries, and discharging through outlet under roller’s push, finally forms pressure conveying of slurries. Lead Equipment as the peristaltic pump for tunnel construction production leader, which could provide peristaltic pump for customers according to the different project demands. For peristaltic pump for tunnel construction, only squeeze hose contact with materials in the use, is only wearing parts for peristaltic pump. Once squeeze hose is worn, operator need change the squeeze hose, usually it will take about 15 minutes to finish. Peristaltic pump for tunnel construction is known as self-priming pump, self-priming height could be up to 5 meters. Peristaltic pump for construction plays an important role in the industry. It has been used in the industrial field for many years and has a long history. The application of the hose pump in the industry is mainly the function of transportation. It belongs to the creeping part of transporting liquid or gas, but it is relative to a difference in peristalsis. Compared with other type pump, peristaltic pump for tunnel construction have some outstanding features, for example, no seals, no valves, dry-running without damage, reversible etc. Every work is done, all need clean the hose using cleaning ball. Use a clean ball with a diameter similar to the inside diameter of the hose from pump inlet to outlet, avoid material clogging hoses due to long periods of inoperative.
Peristaltic pump for tunnel construction can be self-priming, we all know that the screw pump does not have self-priming ability, so in the production often need to use a relatively large tank to raise the material to a certain height, and then forced into the inlet of the screw pump.This increases equipment investment and also requires venues. The hose pump for tunnel construction can completely solve the problem. The hose pump's hose is reset to generate a huge vacuum suction and suck the material into the pump.
