WQ Series Sewage Water Pump 220V For Municipal Engineering , 0.37-7.5KW
Introduction
WQ submersible sewage pump is developed digestion and absorption of foreign advanced technology similar products on the basis of a successful, efficient, anti-winding, non-blocking, automatic coupling, high reliability and automatic control, etc., in the carriage of solid particles and long fiber refuse , has a unique feature.
WQ submersible sewage pump is small, compact, high efficiency, the water level can be automatically controlled according to user requirements, with automatic protection devices and control cabinets, dual-rail system is installed automatically.
Applications
WQ submersible sewage pump is mainly used for municipal engineering, industry, hospitals, buildings, hotels, restaurants and other industries. For sludge, waste, urban sewage discharge conveyor belt and a variety of solid long fibers (including corrosive, aggressive media applications).
Features
♦18.5KW more external circulating water pump automatic cooling, to ensure the safe operation of the electric pump at the lowest level status.
♦Tt the upper end of the pump and motor oil chamber equipped with water probe for monitoring the implementation of the water pump mechanical seal, once the leak, the control system will alarm protection.
♦Vice impeller for balancing mechanical seal external pressure, prevent water from entering the oil chamber, thus extending the life of the pump.
♦Impeller design unique, large passage through the long fibers and dirt, anti-clogging, anti-winding, high flow capacity.
♦Fitted between the impeller and volute lower end of the replaceable wear sleeve to keep the pump running at optimum efficiency.
Operation Mode
♦ the motor rated voltage 380V, frequency 50HZ three-phase AC power.
♦ the transmission medium temperature does not exceed 40oC.
♦ transmission fluid medium PH value 4-10.
♦ the solid phase material transport medium volume ratio of less than 2%.
♦ the transmission medium density of less than 1.2 × 103Kg / m3
| fault phenomenon | failure cause | elimination methods |
| 1.No power supply or one or two phase power supply is needed | Check all phases of power supply and restore power supply |
|
| 2.Poor contact of ac contactor and burning of coil | Repair or replace contactors |
|
| can not start | 3. 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 low | Put water in the sink |
|
| The motor burned | Repair or replace the motor |
|
| 1.Line is loose | Check wiring and tighten connectors |
|
| 2.Frequency converter malfunction | Check 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 normal | 3The frequency converter is damaged | Repair or replace |
| Automatic transmission failure | 4.Pressure switch damage | Repair or replace |
| 5The pressure transmitter is damaged | Repair or replace | |
| 6.Switch failure | Repair or replace | |
| Pump non - suction pressure gauge pointer to beat violently | Insufficient water supply for perfusion, air leakage at the connection between pipeline and instrument | Check pipeline and bottom valve, refill water diversion. Tighten air leakage |
| The pump consumes too much power |
Too much flow, impeller wear |
Check whether the pump shaft is bent, replace the impeller, close the outlet valve to reduce the flow |
