1. Type D: Type D pump for the transport of water without solid particles, temperature slower than 80 degrees C of clean water or physical and chemical similar to clear water liquid, suitable for mining or urban water supply and drainage works.
Type D pump for delivery temperature of -20 c to 105 degrees C, no solid particles of corrosive liquid, can also be used as a second high-pressure boiler for water pump, pump import allowed pressure of 0.6MPa. The user can choose the material of the pump, seal form, structure of the pump and determine the capacity of the motor according to the name, concentration, pump import pressure, use temperature and so on.
The D-pump is used to transport oil and petroleum products with a temperature of -20 c to 105 degrees C, with a viscosity of less than 120 percent.
The D-pump is used to transport mine water and similar liquids containing a small amount of solid particles with a particle diameter of less than 0.5mm and a temperature of less than 80c.
Type D pump for the transport of non-solid particles, temperature below 105 degrees C of clean water, or physical and chemical similar to the liquid of clean water, suitable for medium, hot water-like medium and medium and low pressure boiler water supply or transport hot water and class.
其次便是电的方面了,要了解每台泵电机的功率,对他的操控系统有必定的了解。当多级离心泵用来运送液体中含大,中,小标准的物料的泥浆流时,将液体沿切向喷入筒形室,然后构成涡流,并且将一部分该液体沿切向从该室打扫,将该泥浆轴向喷入该室,该涡流将大标准物料与其他该泥浆和液体分离,将该其他泥浆及液体沿轴向从该室打扫,并将其喷入多级离心泵的进口,运用从该多级离心泵出来的物料作为构成该涡流的喷射液体,然后下降多级离心泵叶轮的磨损并前进多级离心泵功率。下降多级离心泵叶轮的磨损和前进多级离心泵功率的办法,其特征是,它包括:a将液体切向喷入涡流室构成涡流,并且从该室沿切向打扫一部分该液体;b将该泥浆轴向喷入该室,该涡流将大标准的该物料与其他留下来的该泥浆和液体分隔;
