Down-suction submersible pumps, mine bottom-suction pumps, and inverted deep-well pumps are pump types developed by Shenlong pump manufacturers. The pump type can meet 100m3/h, 100m3/h down-suction submersible pumps need to be submerged with YQS and JQS series The motors are connected to form a submersible electric pump, which is submerged into the water as a whole to work. The 100m3/h down-suction submersible pump is suitable for extracting groundwater from deep wells; it can also be used for water-lifting projects such as rivers, reservoirs, and canals; it is mainly used for irrigation of farmland and water for humans and animals in plateau and mountainous areas. It can also be used for cities, factories, railways, and mines. , The construction site is used for water supply and drainage.
100m3/h down-suction submersible pump operating conditions:
1. The voltage deviation of 380V or 660V does not exceed ±5%, and the frequency of 50Hz does not exceed ±1% of the three-phase AC power supply. There are also high-voltage submersible pumps suitable for 1140V, 3000V, 6000V, and 10000V.
2. The inside of the matching motor must be filled with clean water.
3. The submersible electric pump must always work in the water. The water inlet should be immersed in the dynamic water level below 3 meters, the unit should not be immersed in the static water level more than 70 meters, and the bottom of the motor should be no less than 5 meters from the bottom of the well.
4. Submersible electric pumps should have necessary electrical protection measures. Generally, there should be phase failure protection, overvoltage protection, overcurrent protection, and overheating protection. Submersible electric pumps should generally be started at reduced pressure.
5. Water quality:
a. The water temperature is not higher than 20℃ (if the water temperature is higher than 20℃, QJR series submersible electric pump for hot water can be used)
b. The solid impurity content (weight ratio) is not more than 0.01%
c. PH value of pH 6.5-8.5
d. The content is not more than 1.5 mg/L
e. The content of chloride ion is not more than 400 mg/L
f. The 100m3/h downdraft submersible pump does not contain oil.
100m3/h bottom-suction submersible pump components:
The structure of a 100m3/h downdraft submersible pump unit is composed of a water pump, a submersible motor (including cables), a water pipe and a control switch. The submersible pump is a single-suction multi-stage vertical centrifugal pump: the submersible motor is a closed, water-filled, wet, vertical three-phase squirrel cage asynchronous motor, and the motor and the pump are directly connected through a claw-type or middle-key barrel coupling; equipped with different specifications Three-core cable: the starting equipment is air switches of different capacity levels and auto-decompression starters, the water pipe is made of steel pipes of different diameters, connected by flanges, and the 100m3/h downdraft submersible pump is controlled by a gate valve.
100m3/h down-suction submersible pump installation method
1. Vertical use, such as in a general well
2. Inclined use, such as in a sloped roadway in a mine
3. Horizontal use, such as use in a pool, if you have other requirements, you can also ask our manufacturer’s business manager to customize it.
