1. General Description of Type QW centrifugal submersible pump
Type QW centrifugal submersible pump is newly developed on the basis of the advanced technology from international. It's used for industry and commerce, the living area, urban sewage treatment plant, waterworks, civil-air defence construction, hospital, hotel and so on. They can also be used in public works, explore country methane, irragation, deliver water with impurity. The flow-rate range of the delivery water is 7-10000 m3/h, lift range is 7-60m, power range is 0.55-315KW, caliber range is φ25-φ700 mm.
2. what are the service conditions of QW centrifugal submersible pump ?
(1) Medium temperature should not above 60°C, Maximum density is 1.3×103kg/m3.
(2) If the pump without a build-in self-circulation cooling system, its motor should not expose above water more than half.
(3) Deliver medium’s PH value is between 4 and 10.
(4) Solid particle passing capacity is 60% of the inlet diameter, the length of the fiber is 5 times to inlet diameter.
3.What are the structure of Type QW centrifugal submersible pump ?
1) Type QW centrifugal submersible pump adopts particular single blade or double blade; advance the ability for get across feculence. Fiberer ablut 5 times as pump caliber can across.
2) Mechanical seal adopt fresh model cemented carbid.rotproof material, and at the same time, we improved on the airproof to the single-ended double face mechanical seal, let them work in oil chamber for a long peried of time.
3) The whole structure is compact, volume is small, little noise and the energy saving result was apparent. The machine need'nt pump room. It can work just dinning into water, so reduce project cost.
4) The seal oil room has high precision and anti-interference water leakage , testing detector. the pre-cast thermo-sensitive element is in stator winding, it can protect motor.
5) According to need, we can equip safety protection control cupboard to protect the pump, advanced the safety and reliability. The float swich can can control automatically, do not need specially-assingned person. It's very convenient.
6) According to need, we can equip automatic coupler installation system. So people do not need to gert into the drainge ditch.
7) Can be used in all the range of lift, and it won't overload.
8) There are two different install way, fixed type automatic installation system and movable typr installation syatem.
