The swelling power of bentonite is very strong. The reason is that bentonite has strong physical and chemical properties, combined with the ability of water, etc., usually contact with water 24 hours after the start of hydration, and expands 4 to 5 times. After 48 hours of hydration, the particles become 10 to 16 times the gel. A waterproof wall is formed to prevent other water from penetrating, and the permeability coefficient can be reduced to less than 1×10-9 cm / s to achieve a waterproof effect.
Last month, we received an inquiry from an Indonesian customer who wanted to buy a hose pump to pump bentonite in the TBM project. Considering that the bentonite slurry contains 98% H2SO4, we hope to use our hose pump to pump Bentonite slurry is sent, so we offer SS316 joints instead of carbon steel joints.
Usually we will determine the right hose pump for the customer and need to know the output capacity (m3 / h or L / min) and the maximum working pressure. The Gaodetec industrial hose pump uses a spiral bevel gear instead of a cycloid reducer gearbox. Industrial hose pumps have high load carrying capacity and overload resistance, stable operation and long service life. Why are so many customers willing to choose a hose pump for their project? The reason is that the hose pump is more adaptable. Usually the peristaltic hose pump is mainly composed of a pump casing, a rotor, a roller, an idler roller, a squeeze hose and a drive unit. The squeeze hose in the pump room is U-shaped, and the hose is deformed when the rotor drives the drum to rotate. After the roller is rotated, the deformed hose is restored by its elasticity. Therefore, under the push of the hose, the negative pressure generated in the hose attracts the slurry and is discharged through the outlet, eventually forming a pressure transfer of the slurry. Suitable for pumping and transporting large particles and viscous materials in TBM projects.
