Energy-saving effect is remarkable, anti-winding, non-blocking, automatic installation and automatic control and so on. In the carriage of solid particles and long fibers litter, it has a unique effect. This type of 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, making the pump more efficient than high; impeller static and dynamic balance test, the pump is stable and reliable in operation. This type of pump hydraulic performance of advanced, efficient. Structurally diverse, diverse installation, simplifying the pumping station, save and invest. According to JB / T5118-2001 standards. QW / WQ submersible sewage pump product features: 1. Distinctive single or double blade impeller structure, greatly improving the dirt capacity, which can handle fiber material 5 times of pump diameter of about 50% of the pump diameter of solid particles. 2. Mechanical seal uses latest anticorrosive hard tungsten titanium material to enable safe more than 8000 hours of continuous operation. 3. Compact structure, 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. The 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 equipped with automatic control cabinet, the pump leak, leakage overload and overtemperature automatic protection, improved product safety and reliability 6. Float switch can change according to the required level, automatic control of pump start and stop, without special care, extremely easy to use. 7. QW (WQ) series can be based on user needs equipped with dual-rail automatic coupling installation system, it is to install, easy to maintain greater, may not have to get into the sump. 8. Can in a full head, but ensure the motor is not overloaded. 9. There are two types of installation, fixed automatic coupling installation system and traveling free installation system. QW / WQ submersible sewage pump automatic coupling installation system description device system is suitable for long-term fixed occasions, with quick installation, testing, maintenance and easy. The system uses a special base, fixed to the bottom of the sump, and the outlet pipe Quick is good, supporting the bearing blocks installed at the top of the pool, with a guide rod so that the two connected water pump with a particular link bracket good along the guide rod slipped reach base, with its automatic coupling, seals, seals, and when lifting off automatically. Mobile installation system supporting it stand, connect water hose to work in this way is mainly used in emergency or maintenance facilities style needs. QW / WQ submersible sewage pump conditions of use media does not exceed 60 ℃, specific gravity of between 1.0 to 1.3. No internal gravity circulation cooling system pumps, motors partially exposed surface shall not exceed 1/3. Cast iron range of PH value between 5-9. You can select different stainless steel depending on the corrosive media. The main purpose of QW / WQ submersible sewage pumps: for chemical, petroleum, pharmaceutical, mining, paper industry, cement plants, steel mills, power plants, coal processing industry and urban sewage treatment plant drainage systems, municipal engineering, construction sites, etc. containing particles of sewage, dirt, Division also used to pump clean water and corrosive media. Use QW / WQ submersible sewage pumps and precautions before using the pump should be carefully examined whether the cable is damaged fasteners are loose or fall off, the pump in the transport, storage, installation process without deformation or damage. Use the same pump 500V megger between the motor and the relative insulation resistance, and its value should not be less than 2 megohms, or deal with the stator winding drying, drying temperature must not exceed 120 ℃. The pump is equipped with fixed and mobile two. When fixed automatic installation, should the chains respectively wear into (departing from the pump outlet, the wiring should be parallel to the outlet of the pump) two eye bolts or lifting the board up and down lifting pumps. Even slowly fell along the rails until the automatic coupling in place. When a mobile installation, the first hose cover is good, with the chains to wear into the two rings up and down lifting pump, pay attention to not cut the cable as a rope used to avoid danger. After the rotation direction of the pump is turned on from the inlet to rotate counterclockwise as viewed, if pump reverse, just the cable lines swap any two wires at the terminal position. Pump housing ground must be in strict accordance with the relevant rules properly connected, in order to ensure the use of personal safety, pump operation, prohibited in the vicinity of the installation, the water people do? ~ Or moving, just in case pump leakage occurs accident. In the absence of exceptional circumstances pumps must be equipped with automatic pump control cabinet, not directly linked to the grid or use the knife switch to turn on the power, to ensure the normal operation of the electric pump. The pump must not run long in the low lift state (using the usual head of not less than 60% of rated head), it is best to control the lift within the scope of the proposed use, to prevent the pump due to overload and burn out the motor. No self-circulation cooling unit overall out of the water pump is prohibited long run, to prevent pump overheating damage.

After each use, especially for thicker more viscous slurry pump should run into the water for several minutes, leaving deposits to prevent the pump, ensure clean electric pump. Pump as long without the pump should be removed from the water, not long-term immersion in water to reduce the chance of the stator winding is damp, increasing pump life. Fill the pump should be used under normal state every 300-500 hours or replace the oil in the oil chamber (10? 30 oil) so that the mechanical seal to maintain good lubrication, increase mechanical seal life. Pump demolition, repairs, chassis components must be approved by 0.2MPa tightness test checks to ensure reliable electrical sealing. Seal ring between the impeller and pump body having a sealing function, such as seal damage will directly affect the performance of the pump, if necessary replaced.
