Introduction

An overview,
The company developed by QS series of small submersible pumps, suitable for irrigation water, rivers, reservoirs, canals engineering; Also for cities, factories, railways, mines, construction site water supply and drainage. For wet diving pumps designed for vertical motor three-phase asynchronous motor. The advantages of small size, easy installation and use, safe and reliable, long life.
Second, the use environment and working conditions
1, the power frequency 50 hz, the use of the rated voltage of 380 v (tolerance is + / - 5%) of three-phase ac power supply.
2, the content of the water containing solid impurities volume ratio should not exceed 0.1%, the particle size is not more than 0.2 mm.
3, the pH of the medium is 6.5 ~ 8.5.
4, medium temperature does not exceed 40 ℃.
Three, structure features
1, QS series small submersible pumps, diving wet a three-phase asynchronous motor and pump composed of two parts. Motor, water pump, coaxial, middle has reliable (mechanical seal) of the shaft sealing device, can effectively prevent the cooling fluid in the motor and the exchange between pumping liquid, ensure the pump run reliably for a long time.
2, motor winding for polyethylene water resistant nylon sheathed electromagnetic wire. Motor inner cavity injection of clean water for cooling and lubrication bearing, motor using sliding guide bearing and thrust bearing, easy tear open outfit, easy maintenance.
3, the lower part of motor is equipped with pressure regulating membrane, can automatically adjust the motor chamber pressure.
Fourth, the product model:
