| Screw because there may be a variable transmission, self-priming ability, can be reversed to transport the liquid containing solid particles such as the characteristics of the sewage treatment plants, widely used in the transportation of water, the wet sludge and liquid flocculant aspects. Screw pump selection should follow the economy, reasonable and reliable principle. 1) The wide range of pressure and flow. Pressure of about 3.4-340 kgf / cm 2, flow rate of up to 18600cm3 / min; 2) delivery of the liquid type and a wide viscosity range; 3) because of the rotary pump parts, lower inertia, it can be used very high speed; 4) inhalation of good performance, with self-absorption capability; 5) ...... |
