WQ series with cutting device sewage pump introduction
WQ series of sewage sludge submersible sewage pump is mainly used for the discharge of domestic wastewater, sewage, human waste and short fibers containing paper dust, sawdust, starch, sediment, ore particles and other solid suspended solids and non-corrosive media, was pumping liquid Temperature does not exceed 40 ℃, the density is not greater than 1200kg / m3, ph ~ 9. The electric pump adopts double-end mechanical seal and rotary impeller. The impeller adopts stainless steel, which is wear-resistant, non-clogged and non-entangled. It has the advantages of small size, compact structure and convenient carrying. WQK / QG with a cutting device Sewage pump with sewage through the particularly strong, with good cutting performance, the sewage can be long fibers, plastic, paper, tape, cloth, straw, rope and other impurities chopped after the discharge, using the most advanced Method, designed to the most reasonable hydraulic characteristics, the pump can be full-head operation, the best combination of dry-type motor and pump, the total efficiency of the pump to reach the German abs company with cutting device products the same The electric pump uses high-quality cemented carbide, double-sided mechanical seal and skeleton oil seal surface area, shall not exceed the motor height of 1/2, pumping dirt temperature does not exceed 40 ℃. Caution: (1) Before using the pump, first check whether the cable is damaged or not, and cut and pull the cable when the pump is being handled and installed to avoid accident caused by water leakage after the cable ruptures. If the cable should be replaced immediately after the cracked cable. And check with megger insulation resistance of the pump is normal (insulation resistance of not less than 1 megohm) (2) recognize the ground wire (usually yellow or green ground or connected with a grounding mark), according to the provisions of the process properly line. (Our grounding wire is equipped with a grounding mark). (3) Choose the appropriate protector (such as earth leakage protector, air switch, open-phase overcurrent protector, etc.) Do not use the knife switch directly connected. (4) According to the standard connected to the power cord, try the power supply, check the pump is operating properly, and determine the steering is correct, if the steering is not correct, the three power lines in any two of the exchange can be good (Note that operation Time can not exceed half a minute). (5) Install the outlet pipe and outlet hose (or iron pipe), knot good ropes on the handle of the electric pump (never use the cable instead of the function of the sling), put the electric pump into the pumped liquid and connect Power, you can use. (6) In order to ensure personal safety, it is forbidden to install the sewer operation near the electric pump (such as moving or checking, troubleshooting, etc.) during the electric pump operation. Contact the electric pump in case the electric pump leaks and an accident occurs! (7) Do not expose the pump to the water as a whole Long-term operation (or short-term operation) Electric pump "on", "stop" should not be too frequent to prevent motor overheating damage (8) long-term pumping high sand content of liquid WQK / QG With cutting device sewage pump over-current components wear larger, it is recommended to use our factory cyclone sewage submersible pump products. (9) If you find WQK / QG cutting device with sewage pump in operation, there is no turn, the protection of the trip, the fuse blown and other abnormal phenomena, should immediately cut off the power, check the power protection wiring and other problems if these external Device is normal, it may be a fault pump, this time should not continue to use to avoid accidents!
