Introduction

An overview,
QJR series well submersible pumps and submersible pumps with hot water is made up of hot water well dive directly got behind one of the three phase asynchronous motor with hot water. Hot water temperature can reach 100 ℃, dive into the geothermal water, to extract the effective implement of geothermal water, geothermal is a kind of cheap, clean energy, now is widely used for heating, medical treatment, bath, breeding, cultivation, agricultural and industrial, factories and mines enterprises, entertainment service care facilities and many other aspects. This machine has the pump combination, simple structure, reliable operation, no noise, good performance, high efficiency, easy installation and maintenance, and has many characteristics, such as heat resistance, anti-corrosion, anti-aging is to extract the latest products of geothermal water.
Second, the use environment and working conditions
1. Solid matter content less than 0.01% (weight ratio);
2. Water pH pH value of 6.5 ~ 8.5 range;
3. The content of chloride ion in water is not more than 400 mg/l;
4. Salinity is not more than 4000 mg/l;
5. Sulfuric acid root is not more than 1000 mg/l;
6. Ammonium ion is less than 1 mg/l;
7. Fluorine ion of no more than 4 mg/l;
8. Hydrogen sulfide is not more than 1 mg/l;
9. Power frequency 50 hz (allow no more than plus or minus 1%), rated voltage 0.38/0.66 kV, 0.66/1.14 kV, 3 kV and 6 kV (tolerance is + / - 5%) of the three-phase ac power;
10. The motor chamber must be full of pure water;
11. The well tube should be integrity, smooth, can not have prominent or tube dislocation phenomenon, caliper is not less than the use of hot water submersible electric pump Wells.
Three, the structure
QJR series of Wells with submersible electric pump hot water unit contains: hot water, hot water pump submersible motor, including heating cable, water pipe and control switch (high lift pump and gate valve) four major components.
1. Hot water submersible pump is single-suction multi-stage type centrifugal pump, the diversion shell, impeller, seal ring, taper sleeve, pump shaft, heat-resistant bearing, water section. Main parts of check valve and the valve body.
2. Hot water submersible motor for sealing water wet three-phase asynchronous motor, the stator, rotor, upper and lower bearing seat, sand control device, main components of the pressure regulating device.
3. Hot water and hot water pump submersible motor through the sleeve coupling or claw coupling directly couplet body, composed of submersible pump hot water unit.
4. Hot water submersible motor installed in the upper sand control cover and two reverse assembly of skeleton oil seal, the sand control devices. In addition, according to user needs, can be installed sealed sand control module.
5. Hot water submersible pump per level of connection for the diversion shell thread and positioning of the mouth close connection, keyway fixed impeller and the pump shaft must be conducted by special chassis positioning assembly.
6. Heat resistant submersible motor stator connected to upper and lower bearing seat and the base, fixed, the stud with sealing rubber ring and connection end location check mouth closely.
7. Hot water machine top is equipped with water injection hole, vent, a lower plughole, when under the electric pump well before, in the hot water submersible motor chamber must be full of pure water, pay attention to prevent false full, for each hole plug, can not have leakage phenomenon.
8. Motor stator winding of the high quality nylon sheathed by cross-linked polyethylene insulation irradiation of heat, water resistant, electromagnetic wire, electric heat fuses with water resistant heat sealed electromagnetic wire connection mode and external heating cable and heat sealed lead mode basically the same article 4 in the equipment installation and use of the insulation of the cable joint processing, finally check the cable is not less than 100 m Ω joint.
9. The external surface of the heat resistant submersible pumps have been treated against corrosion.
10. Lower lumen is equipped with upper and lower motor thrust bearing, thrust plate (skateboard), of which the stainless steel under the thrust bearing and thrust plate mill, pump down under the axial force and the weight of motor rotor. The thrust bearing and thrust plate mill, bear axial force of pump up.
11. The motor chamber lowermost with heat-resistant rubber membrane voltage regulator, surge chamber is used to regulate the water volume of compensation caused by temperature and pressure changes.
