QJR hot water submersible pump product instruction
QJR series of well water submersible pump is composed of a waterpump and well water submersible three-phase asynchronous motoris directly connected to the. Heat the water temperature can reach 100 ℃, diving in geothermal water, effective tool for extractinggeothermal, geothermal energy is a new energy is cheap, clean,widely used for heating, bathing, medical, breeding, cultivation,agricultural, industrial and mining enterprises, entertainment and many other aspects of health care facilities.
QJR well with hot water submersible pump is a pump machine, has the advantages of simple structure, reliable operation, no noise,good performance, high efficiency, convenient installation and repairunit, and has heat resistance, anti-corrosion, anti-aging and many other characteristics, is the extraction of hot new products.
QJR hot water submersible pump struction instruction
QJR series of well water submersible pump units include: hot water,hot water submersible pump submersible motor (including heat-resistant cable), a water pipe and a control switch (high lift pumpwith valve) four parts.
1. Hot water submersible pump single suction multistage centrifugal pump, the guide housing, impeller, seal ring, the conical sleeve,pump shaft, bearing, heat water festival. Inverse main parts valveand valve body.
2. Hot water submersible motor for sealing water wet the three-phase asynchronous motor, composed of a stator, rotor, upper and lower bearing seat, anti sand device, adjustable pressure device of main parts.
3. Hot water pump and water diving motor through a sleeve couplingor claw coupling directly into one, consisting of hot watersubmersible pump.
4 .Hot water submersible motor upper mounting sand cover and two reverse assembly skeleton oil seal, namely anti sand device.According to user needs, can be installed sand sealing module.
5 .The connection of hot water submersible pump every class isconnected guide housing thread and stop positioning keyway fixing,impeller and pump shaft must be assembled by the position of the chassis dedicated.
6 .Heat resistant submersible motor stator and on the lower bearing seat and a base, a connecting seat, fixed, the double headed boltsealing rubber ring and the end stop opening positioning close connection.
7 .The motor is arranged on the upper end of hot water injection hole, vent hole, the lower end is provided with a drain hole, when the electric pump, hot water submersible motor cavity to be filled with pure water, pay attention to prevent the false man, on eachhole plug, no water leakage phenomeno.
Before opening the pump, suction pipes and pumps must be filled with liquid. Open pump, the impeller rotating speed, which leaves the liquid together with the rotation, under the action of centrifugal force,flying away from the impeller injection, injection of the liquid in the pump shell gradually slow the proliferation of indoor speed, the pressure gradually increased, and then from the pump outlet, the outflow discharge tube. At this time, the blade center of low pressurearea due to liquid was thrown neither to the surrounding air to formand no liquid, liquid pool at the surface of the liquid under the action of atmospheric pressure, through the suction pipe into the pump, the liquid is continuously pumped up from the liquid pool is also a continuous from the outflow discharge tube.
