Pump industry suppliers to tell you: what are the typical features of multi-stage pump

the characteristics of multistage pump

multistage pump is in and out of the water with middle, by stick together in a centrifugal pump, it can output water pressure is very big, is also rely on the rotation of the impeller in the centrifugal force, so as to materials, for gas density to achieve mechanical vacuum pump was out working range, and thus gradually obtain high vacuum.

the basic construction of multistage pump is composed of inlet section, outlet section, middle, end cover, impeller, pump body, pump shaft, bearing, seal ring, stuffing box etc.

1, the impeller is the core part of the multistage pump, its speed is higher than strength, on the impeller blades and play a major role, the impeller through static balancing experiments before assembly. Impeller on the inside and outside for smooth surface to reduce friction loss of water. Sealing ring is also called the minus leakage ring. Import and pump impeller shell gap between in the cause of high water in the pump by means of this clearance flow to the low pressure area, affect the water yield of pump, efficiency!

2, the function of multistage pump shaft is connected by coupling and motor, the torque of the motor to the impeller, so it is a major part of the mechanical energy transfer. Inlet section, outlet section, the middle is also called the pump shell, it is the main part of the multistage pump, support fixed effect, and connected to install bearing bracket.

4, bearing is set on the pump shaft support, pump shaft components, which has two kinds of rolling bearing and sliding bearing. Rolling bearing use butter as a lubricant oil is generally appropriate for two-thirds to three-quarters of the volume too much will be fever, too little and there was a noise and fever!

5, stuffing box is mainly composed of filler, seal ring, packing, packing gland, water tubes. The role of the stuffing box is mainly in order to close the gap between pump casing and pump shaft, don't let the flow within the pump does not flow outside to not let outside air into the pump. When the pump shaft and be about to rely on water seal packing friction heat to hold water to the water seal circle packing cooling!

water pump industry suppliers is the collection scientific research, design, production, management, services for the integration of production enterprises, the products are widely used in petroleum, chemical industry, metallurgy, electric power, mining, coking, medicine, printing and dyeing, food, paper making, environmental protection and other fields. The company has a modern water pump performance testing means, equipment is excellent. Main production ZA, ZAO, ZE petrochemical pump, multi-stage water pump CZ chemical process pump, IH chemical 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. 。
