Machines commonly used to pump, deliver and pressurize fluids are collectively referred to as pumps. From an energy standpoint, a pump is a machine that converts energy. It transforms the mechanical energy of the prime mover into the energy of the fluid being delivered, increasing the flow rate and pressure of the fluid. In the past, the pump was used to deliver only water at room temperature, so it is often called a water pump. Now, the pump can transport all kinds of liquid at normal temperature, but also can transport liquid and liquid metal with temperature up to 800 ℃. It can also transport cryogenic liquid such as liquid oxygen and liquid hydrogen at temperatures around minus 200 ℃. Large or single-channel Impeller pumps can also deliver liquids with solid particles (solid particles up to hundreds of millimeters in diameter) such as coal, ore, fish, beets, etc. Centrifugal pumps with chopped blade impellers can also be used to transport liquid Plastic bags, nylon ropes, straw, sanitary napkins and other long fiber objects tear, chopped, forming a good non-blocking delivery. Pumps, as a kind of general machinery, are now widely used in all fields of the national economy. Agricultural irrigation and drainage, urban water supply and drainage require a pump. In all sectors of industrial production, pumps are an indispensable device. As in the city's high-rise buildings require variable frequency water pump, fire pump, spray pump, pipe pump, multi-stage pump, water pump shield, submersible sewage pump. In the power industry need boiler feed pump, forced circulation pump, circulating pump, condensate pump, ash pump, drain pump, kerosene pump; In the mining industry need mine drainage pumps, water sand filling pump, Etc .; in the oil industry need mud pump, water pump, deep well pump, submersible pump, oil pump, oil refining pump; in the chemical industry need corrosion-resistant pumps, process pumps, pumps, shielded pumps, magnetic pumps , Metering pumps, etc .; in the transportation industry need fuel pump, fuel pump, lubricating oil pump, hydraulic pump and so on. Pump Category: Many types of pumps, according to their working principle, characteristics and uses to be classified. In addition to the above basic classification methods, there are other classification methods. According to the use of different sectors can be divided into industrial pumps and agricultural pumps, and industrial pumps can be divided into chemical pumps, oil pumps, power plants with pumps, mining pumps; according to their different properties of liquid transport can be divided into Water pump, sewage pump, oil pump, acid pump, liquid ammonia pump, mud pump and liquid metal pump; according to pump performance, use width and structure characteristics can be divided into general and special pump pump; Divided into low pressure pump, medium pressure pump, high pressure pump and high pressure pump. With the development of pump products, pump classification is also evolving. The use of various types of pumps is different. As can be seen, the largest area occupied by the centrifugal pump. The general flow of 5 ~ 2000m. / h, head in the range of 8 ~ 2800m, the use of centrifugal pump is more appropriate. Because in this performance range, centrifugal pump with high speed, small size, light weight, high efficiency, large flow, simple structure, stable performance, easy operation and maintenance advantages. Production practices at home and abroad show that the output value of centrifugal pumps in pump products is also the highest. Shijiazhuang Zhi Qian Mechanical and Electrical Equipment Co., Ltd., mainly produces various types of submersible sewage pumps, sewage pumps and other submersible sewage treatment equipment.
