Usage and Characteristics:
The QJ type submersible electric pump for wells is an energy-saving product designed according to national standards, widely used for irrigation in farmland, water supply and drainage in industrial and mining enterprises, and water for people and livestock in high-altitude and mountainous areas.
This type of pump is composed of a QJ submersible pump and a YQS submersible motor, which work together underwater. It has the characteristics of simple structure, small size, light weight, easy installation and maintenance, safe and reliable operation, high efficiency and energy saving
The QJR type heat-resistant submersible pump for wells is directly integrated with a heat-resistant submersible three-phase asynchronous motor for wells, assembled into a heat-resistant submersible electric pump. The heat-resistant water temperature can reach 100 ℃, making it an effective tool for diving into wells and extracting geothermal water. Geothermal energy is the cheapest, cleanest, and inexhaustible latest energy source, widely used in heating, medical treatment, fish farming, planting, industry and agriculture, industrial and mining enterprises, entertainment services, health facilities, and many other fields. It has the advantages of pump machine integration, simple structure, reliable operation, no noise, excellent performance, high unit efficiency, convenient installation and maintenance, heat resistance, anti-corrosion, anti-aging and many other advantages, and is the latest product for extracting geothermal water.
Usage conditions:
1. Power requirements:
(1) The rated frequency is 50 Hz, and the rated voltage at the motor end should be ensured to be 380 ± 5% volts for a three-phase AC power supply (if the user's voltage is 660 volts, special orders are required).
(2) The load power of the transformer should not exceed 75% of its capacity. (3) When the transformer is far away from the well, the voltage drop of the transmission line should be considered. For motors with a power greater than 45KW, the distance from the transformer to the wellhead should not exceed 20 meters. For high lift submersible electric pumps Due to the long length of the transmission line, it is necessary to consider the line voltage drop loss, and it is required that the specifications of the transmission line be two levels larger than those of the matching cable. Using a single transformer for power supply, the output voltage of the transformer is required to be 400V-440V
2. Water quality requirements:
(1) Generally non corrosive clean water.
(2) The sediment content in the water shall not exceed 0.01% (mass ratio)
(3) PH value within the range of 6.5-8.5
(4) The chloride ion content in water shall not exceed 400 milligrams per liter.
(5) The hydrogen sulfide content shall not exceed 1.5 milligrams per liter.
(6) The QJ pump requires a water temperature not exceeding 20 ℃. The QJR heat-resistant submersible electric pump has a water temperature requirement of no more than 100 ℃.
(7) Does not contain oil.
3. Requirements for wellbore:
Positive value, smooth, without any protrusions or misalignment of the pipe well And the inner diameter shall not be less than the corresponding machine base number.
