Pump industry suppliers - Press filter feed pump has to take off the shaft in the process of application

by:J&T     2020-10-27

press filter feed pump to take off the shaft condition occurs in the application process, but such things are very few is basically a one over one thousand chance. Appear such things about several reason lead to the following:

1, fatigue damage. According to the total flow of the pump and the speed ratio is proportional, according to the change of pump tape wheel diameter change speed ratio, thereby reducing the total flow of the pump, pump head, in the work scope of operation with high efficiency, improve labor efficiency and reduce the shaft torque, reduce the level of fatigue damage.

press filter feed slurry pump for an instant of filter press filter room work flow back pressure reaction on the pump shaft in a flash with the shaft torque is in turn, long-term fatigue damage the pump shaft compressive strength is reduced. Should be flexible use of automation control system software to maintain pressure filter into material cut-off valve and feed pump and turn off, modification or use of the blowing wind flow back into the tube will filter press work flow back pressure dispatch to the vertical mixer, in order to reduce the damage to the pump shaft.

2, unqualified material. Press filter feed pump pump shaft materials generally choose chrome vanadium steel or chrome vanadium steel, molybdenum unqualified material is the key reason of pump shaft damage.

3, installation is not accurate. Among them, R for line constant, and the pipe diameter is inverse ratio, and the piping material specification and pipe water gate open degree, to take over the length and the frictional resistance index elements such as are linked. Filter press and quick opening pressure filter into the feed tube, box type filter press into the feeding pipe bend over short, thin diameter, feed valve open degree of kinetic energy in different result in pipeline damage, the box-type pressure filter feeding pump working condition point in the work category, cause a large total flow.

category 4, traffic migration work. By the press filter feed pump characteristic curve can see the total capacity of filter press feed pump, pump head, output power, high efficiency in high efficiency within the scope of work values, the category, in the area of the filter press feed pump efficiency are asked pump basic theory work area.

pump industry suppliers is the collection scientific research, design, production, management, services for the integration of production enterprises, the company has a modern self-priming water pump performance testing methods, equipments. Main production pressure filter feed pump, ZAO, ZE petrochemical pump, CZ chemical process pump, IH chemical water pump, forced circulation pump, SPP chemical mixed-flow pump of 28 kinds of material, 30 series more than 1000 specifications special alloy chemical pumps, valves, stainless steel pipe, fluorine pipe parts. 。
