WQ AND QW SERIES NON-CLOG SUBMERGED MOTOR PUMP

Transcription

1 WQ AND QW SERIES NON-CLOG SUBMERGED MOTOR PUMP PRODUCTS PROFILE WQ and QW series non-clog submerged motor pumps are strictly designed, manufactured and tested according to relative national standards. They are applicable for commercial wastewater, daily wastewater, drainage system ofcity wastewater. Flow extent ranges from 5~6000m 3 /h, head extent from 5~60m, power extent from 0.55~315KW and caliber extent from Φ25~Φ600mm. PRODUCT FEATURES 1. Its unique single-vane or double-vane impeller structure contributes much to pollutant handling capacity. It enables to effectively deliver fibers 5 times of pump caliber and solid granules of diameter at 50% of pump caliber; 2. Its mechanical seal uses late-model corrosion-resistant carbon tungsten hard alloy. In addition, seal is upgraded to double-end sealing forlong-term operation in oil chamber and safe service ofcontinuouslymore than 8,000hours. 3. Compact overall structure, small volume, low noise, distinctive energysaving, easy maintenance, no need for a pump room, service whilebeing put into water, and low construction cost. 4. The sealed oil chamber ofthis pump is provided with highprecision anti-interference water leakage detection sensor. That is to say,athermosensitive element is pre-embedded inside stator windings toeffect full protection to pump motor. 5. A full automatic safety protection control cabinet is available if required to fully prevent pump from water leakage, electric leakage, over load and excessive temperature and so on. In this way, the safety and reliability is greatly enhanced. 6. The float ball switch may automatically control the start and stop of pump responding to the changes ofrequired liquid level. It is fairly easy to use with no need for a special person to care about it. 7. Double-guide automatic coupling installation system is available if required, making installation and maintenance much convenient, sothat there is no need for a person to go into sewage pit. 8. It can be used within full head extent and prevent motor from overload. 9. Two different installation types, fixed automatic coupling installation system and portable free installation system.

2 APPLICABILITY WQ and QW series non-clog submerged motor pumps are applicable for the discharge of seriously polluted wastewater in factories and commercial sites, sewage draining station in residential area, drainage system in city wastewater treatment plant, draining station for civil defense, water supply in tap water plant, sewage discharge in hospitals and hotels, construction sites ofmunicipal projects, exploration, ines, rural methane pool, agricultural irrigation etc. to deliver wastewater and pollutants containing granules, as well as clean water and corrosive mediums. SERVICE CONDITIONS A. Medium temperature not exceeding 60 C and medium weight from 1~1.3kg/dm 3. B. For pumps without internal artesian cycle cooling system, the revealed part ofmotor above liquid should not exceed 1/3. C. The applicable scope of cast-iron material is from PH5~9. D. For 1Cr18Ni9Ti stainless steel material, ordinary corrosive mediums may be used. E. The height above sea level ofservice location should not exceed 1000 meters. If beyond, clarify when placing an order for our convenience to provide you with more reliable products F. Note: If there are special requirements on temperature and mediums, please clarify the detail ofthe medium to deliver when placing an order for ourconvenience to provide you with more reliable products. STRUCTURE DRAWING OF PUMP Motor Cover Terminal Block Connection End Cover Pump Shaft Rotor Stator Motor Shell Bearing Oil Box Sealing Component Sealing Ring Gland Gasket Bolt Pump Casing Impeller Sealing Ring Base Cable Hook Protector For pumpwith full automatic safetyprotection control cabinet,there is a water leakage detection probe.in case ofwater leakage arising, the probewill send out signals to enable control system carrying out protection to pump. Motor stator uses class-b and class-f insulation, with a thermal protection sensor mounted inside. For pumps over Ф200 in caliber, external cycle cooling system is available if required responding to service conditions to ensure normal operation under the lowest water level. Awater leakage detection probe is mountedin oil chamber. Whenmechanical seal is damagedandwater runs into oil chamber the probe will sendout signals to enable control system carrying out protection to pump. Double-endmechanical seal ensures the reliable operation of pump. The unique impeller is provided with considerable flow rate to deliver large objects and fiber. Reliable abrasion-resistingring is mountedbetweenimpellerand pump body to ensure most efficient operation. 2 visit us online at
