Charteristic description

1.Pump

QH series seawater submersible pump is vertical muftistage centrifugal pump.which consists of pump shaft, impeller, casing,shaft sleeve, wear ring and other parts etc. According to different working conditions, pump parts separately select relevant material. When using in clean water. When using in seawater or similar corrosive liquid, the main material is normally Cu-Ni alloy or stainless steel. In order to extend the life cycle and raise the quality of pump, besides choosing the superior materials and precisely fabricating on products,we continuously improve on structure of products and process of technology.

2. Motor

The motor matched with above pump is electric water (seawater) submersible 3-phase asynchronous motors,which is of wholly sealed construction full of clean water. Stator windings are wound with polyethylene insulation nylon covered winding.According to different working conditions, the extemal surfaces of motor are all made of relevant corrosion-resistant metal. Motor adopts mechanical seal or oil seal for moving seal. Motor bearings are of self-lubrication, and are lubricated by clean water or coolant Motor cable is corrosion-resistant and water-resistant flat or round cable with guard sleeve.

4. Advantage

1) Stainless steel pump outlet head with sand storage keep anti sand completely ,bottom can’t to get stuck
2) Dehydration does not burn the motor and impeller unstuck,no need worry about improper use problem
3) All motor copper winding overheating overcurrent protection
4) Ceramic bearings of high wear-resistant rubber sleeve is more durable
5) Stainless connector shaft and pump,Precision molding, high efficiency
6) Stainless Connecting seat, convenience maintenance and repair,the high precision mounted impeller
7) Stainless impeller,entire pump no rust contamination for you to drink clean water

Working conditions of seawater submersible pump:

1. Three-phase power supply, voltage 380V (error less than 5%), frequency 50Hz (error less than 1%).
2. Motor must be filled with clean water.
3. The primary impeller of the pump should be immersed at least 2m under dynamic water level. The pump unit shall be less than 70m deep under static water level. The foot of motor shall be at least 3m above well bottom.
4. Water temperatureshould not higher than 20 ℃.
5. Sand content of the water (by quality) not more than 0.01%.
6. Water PH 10.
7. The content of hydrogen sulfide in watershould not be more than 1.5 mg/l.
8. The content of chloridion in water shouldnot be higher than 400mg/l.
9. The water source must provide enough water for the pump to work continuously
