Product name: Sludge 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.

| 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 |
