Sewage Pump with Not Easy Wear and Not Clogging Pipes

Product name: Sewage Pump of Qw not easy to wear and clogging pipes Scope of application: Sewage pumps are widely used in various fields, sewage pump can transport with hard solids, fibers and liquid, particularly dirty, sticky and slippery liquid, the sewage pump is widely Used in mines, papermaking, printing and dyeing, environmental protection, oil refining, petroleum, chemical industry, farm, dyeing, wine, food, chemical fertilizer, coking plant, building, marble factory, mud, sand, mud, dirt Tang, the dirty liquid feed suction sewage treatment of thick liquid, charging and suspended matter in. 1, enterprises discharge waste water. 2, city sewage treatment plant discharge system. 3, the subway, underground civil air defense system, drainage pumping station. 4, hospital, hotel, building sewage discharge. 5, residential sewage pumping station. 6, municipal engineering, construction sites in the dilute slurry discharge. 7 water plant, water supply device. 8, wastewater emissions and rural farmland irrigation. 9, exploration and mining equipment for water treatment. 10, instead of the shoulder arm, sucking mud. Mechanical characteristics 1, using a unique single or double blade impeller structure, greatly improving the through capacity of sewage, can effectively through the fibre material 5 times of pump diameter and solid particles 50% of Pump diameter. 2, the mechanical seal of tungsten carbide material decay using a new type of rigid, and double seal to improve sealing, the long run in the oil chamber, can pump the security more than 8000 hours of Continuous operation. 3, compact structure, small volume, low noise, energy saving, convenient maintenance, no need of pump room, dive into the water to work, greatly reducing the project cost. 4, the oil chamber is provided with a Water Leakage interference detection sensors of high precision seals the pump, and the stator winding embedded within the thermal components, the absolute protection of The pump motor. 5, according to the user need to be equipped with automatic safety protection control cabinet, the pump Water Leakage, leakage, overload and over temperature and so on absolute protection, improved product Safety and reliability. 6, float switches can be changed according to the required level, automatic start and stop the pump, without special care, is extremely easy to use. 7, can be fitted with double rail automatic coupling installation system, which brings great convenience to the installation, repair, but this may not enter the sewage pit. 8, can be used within the scope of the whole head, while the motor is not overloaded. 9, there are two types of installation, fixed automatic coupling installation system, mobile free installation system Product overview: 1. Sewage pump of QW SeriesSubmersible sewage pump is non clogging sewage pump imported high efficiency and energy saving, the organization of the unit technology developed from, the performance indicators have reached or exceeded the level of similar products at home and abroad. 2. As unique single channel impeller, seal with hard alloy mechanical seal device two sets of special materials, separate motor oil chamber, with no blockage, durable, profile accuracy, convenient repair and use, high efficiency, energy saving, is China's pump replacement of new products, welcomed by users. 3. The pump has a variety of models and different structural forms are available. fault phenomenonfailure causeelimination methods 1.No power supply or one or two phase power supply is neededCheck all phases of power supply and restore power supply  2.Poor contact of ac contactor and burning of coilRepair or replace contactors can not start3.The power switch is not closed, malfunction or damaged Close the switch and replace it if the power indicator does not turn on 4.Thermal relay trip or damage Check whether the motor is blocked, find out the reason and eliminate it.Manual reset is replaced if it cannot be started Water level is too lowPut water in the sink  The motor burnedRepair or replace the motor  1.Line is looseCheck wiring and tighten connectors  2.Frequency converter malfunctionCheck the fault content, check the cause according to the frequency converter manual, and restart after reset.Or disconnect the inverter power supply for a few seconds, the inverter fault reset before starting.The manual is normal3The frequency converter is damagedRepair or replaceAutomatic transmission failure4.Pressure switch damageRepair or replace 5The pressure transmitter is damagedRepair or replace 6.Switch failureRepair or replacePump non - suction pressure gauge pointer to beat violentlyInsufficient water supply for perfusion, air leakage at the connection between pipeline and instrumentCheck pipeline and bottom valve, refill water diversion.
