A, QW submersible sewage pump Product Overview: QW-type submersible non-clog sewage pump is the introduction of foreign advanced technology, based on the combination of domestic water pump features the successful development of the new generation of pumps, energy-saving effect is remarkable, the anti-wrap , no plug, automatic installation and automatic control and so on. In the carriage of solid particles and long fibers litter, it has a unique effect. Series pump uses a unique structure of the impeller and new mechanical seal, it can effectively contain solids conveying and long fibers. Compared with the conventional impeller impeller, the pump impeller flow channel or double channel single form, which resembles a cross section of the same size elbow, the flow of a very good, with reasonable cochlear room, so that the pump has efficiency high impeller static and dynamic balance test, the pump no vibration during operation. Advanced hydraulic performance, mature products have been tested the performance indicators have reached the standards, products on the market with its unique efficacy and reliable performance, stable quality received the majority of users of welcome and praise. Two, QW submersible sewage pump Features: 1, a unique monolithic or double blade impeller structure, greatly improving the dirt capacity, which can handle fiber material 5 times of pump diameter of the pump diameter of about 50% solids. 2, the mechanical seal with anticorrosive hard tungsten titanium material to enable safe more than 8000 hours of continuous operation. 3, the overall structure is compact, small size, low noise, energy-saving effect is remarkable, easy maintenance, no need to build pumping stations, dive into the water to work, greatly reducing the project cost. 4, QW (WQ) type non-clogging submersible sewage pump seal oil chamber with high precision interference leakage detection sensors embedded in the stator windings of the thermal components, automatic protection of pump motor. 5, according to user needs with automatic control cabinet, the pump leak, leakage overload and overtemperature automatic protection, improved product safety and reliability 6, the float switch may vary according to the required level, automatic to control pump start and stop, without special care, extremely easy to use. 7, QW (WQ) type non-clogging submersible sewage pump can be fitted with double guide rail automatic coupling installation system, it is to install, easy to maintain greater, you may not have to get into the sump. It can be operated within full head, and ensure the motor is not overloaded. 9, there are two types of installation, fixed automatic coupling installation system and traveling free installation system. Three, QW submersible sewage pump range: Flow: 8-2600m3 / h; Head: 5-60m; power: 0.75-250kw; Speed: 580-2900r / min; caliber: 25-500mm; temperature range: ≤60 ℃. Non-clogging submersible sewage pumps are suitable for factory business seriously polluted wastewater discharge and residential sewage stations, urban sewage treatment plant drainage systems, air defense systems drainage stations, water plants supply equipment, hospitals, hotels of sewage, municipal engineering construction sites exploration, mining matching attached machine, rural biogas digesters, irrigation and other industries, the belt particles of sewage, dirt, can also be used to clean water and corrosive media. Four, QW submersible sewage pump conditions of use: 1, medium temperature does not exceed 60 ℃, medium gravity of 1 ~ 1.3kg / dm3. 2, without internal artesian cycle cooling system pumps, motors partially exposed surface of not more than 1/2. 3, under normal circumstances, the use of lift pump must be within range, to ensure that the motor is not overloaded, for use in the whole head, should be indicated in the order for manufacturers to manufacture. 4, during operation, the pump motor current must not exceed the rated current of the motor. Five, QW submersible sewage pump Model significance: For example: 40QW (WQ) 15-30-2.2 40- Diameter (mm) QW (WQ) - 15- submersible sewage pump flow rate (m3 / h) 30- lift (m) 2.2- With motor power (kw)
