Conditions of Use:
Rated frequency 50HZ, rated voltage 380V or 660V three-phase AC power supply. The electric pump should be immersed in water for operation, and the diving depth requires that the inlet joint should be below one meter of the dynamic water level. The working medium should be non corrosive clean water, with a pH value ranging from 2 to 13 and a sand content not exceeding 0.01% (by mass). The water temperature should not exceed 20 ℃. Vertical installation, upright wellbore, and no misalignment of wellbore pipes.
The QH stainless steel submersible pump is made of stainless steel 304 or 316 material, and the product introduces advanced production technology from abroad. It has the advantages of exquisite appearance and reliable operation. This series of products is a submersible electric pump for wells that is directly connected to the pump and operates in water. The structure is slender and elongated. Single stage or multi-stage water filled wet three-phase asynchronous motor submersible electric pump. Stainless steel submersible pump is a type of submersible pump, because many submersible pumps are made of cast iron or plastic materials. If only these materials are used to make submersible pumps, it is difficult to meet customer needs. If there are many corrosive media, such as sulfuric acid, hydrochloric acid, nitric acid, etc., they cannot be discharged; This is one of its characteristics. It is a specialized drainage system developed for agricultural irrigation, sprinkler irrigation, mining, seawater firefighting, industrial and civil buildings. It is suitable for ponds, fish ponds, water towers, deep well water lifting, high-rise water supply, and fountains.
QH series stainless steel submersible electric pump features:
1. The motor and water pump are submerged in water for safe and reliable operation.
2. There are no special requirements for well pipes, as long as the water pipes can withstand the corresponding pressure.
3. Easy to install, use, and maintain, with a small footprint and no need to build a pump room.
4. Simple structure, saving raw materials.
Usage environment and conditions
1. A three-phase AC power supply with a power frequency of 50Hz and a rated voltage of 380V or 660V (tolerance+-5%).
2. The solid content (by mass) shall not exceed 0.01%.
3. The acidity pH value of the liquid being pumped is 1-14.
4. The temperature of the conveying medium shall not exceed 120 ℃.
5. The inlet of the water pump must be below the dynamic water level of 1m, but the diving depth should not exceed 70m above the static water level. The lower end of the electric pump should be at least 1m away from the bottom of the well.
6. Require the well to be upright, the well wall to be smooth, and the well pipes to not be staggered. If the water tank is used, a radiator (guide cover) needs to be added.
The QW type sewage submersible pump product has been tested and qualified by the National Machinery Product Quality Monitoring Center. This series of products has the advantages of high flow rate and high head, but the flow rate and head of the product are inversely proportional to each other. Please make a reasonable selection when making a purchase.
