WL vertical sewage pump and WW non clogging sewage pump
WL type sewage pump is a type of impurity pump, which differs from clean water pump in that the impeller has fewer blades and wider flow channels,
Easy to transport wastewater containing fibers or other suspended impurities. In addition, there are inspection and cleaning holes on the casing of the pump body, which facilitates
Clean the impurities inside the pump casing after parking.
The WL series vertical sewage pump has high efficiency and good energy-saving effect. The structural characteristic is having single or double lobes, and
Adopting a large flow channel form to reduce fiber waste entanglement and allow for the passage of large materials. Capable of pumping with a diameter of 100-250mm
A large particle solid block with a fiber length of 300-1500mm. In addition, the power curve of the WL series vertical sewage pump is flat,
It can operate within the full performance range without worrying about overload.
The WL series vertical sewage pump is suitable for conveying urban domestic sewage
Wastewater, mud, feces, ash, pulp and other pulp from industrial and mining enterprises, as well as
Can be used as a circulation pump, water supply and drainage pump, and other purposes.
The WL series pump is a single stage single suction vertical sewage pump, mainly composed of a volute
Composed of shell, impeller, pump seat, support pipe, shaft, motor seat, etc,
As shown in Figure 2-17. Hand holes are installed on the pump body and inlet pipe for drainage
Discharge debris, liquid is sucked in axially and discharged horizontally. Pump transmission
The method is connected to the motor through a coupling, and the WL (I) type is vertical
The electric motor is directly connected to the water pump, and the WL (II) type is a vertical electric motor
The coupling of the extended shaft is connected to the water pump. The rotation direction of the pump is from electric
The motor end rotates clockwise.
The WW type non clogging sewage sewage pump is a single-stage single suction centrifugal pump, which is a new type of impurity pump. Its structure is shown in the figure
As shown in 2-18. The pump adopts a single blade flow channel closed impeller, and the inlet and outlet diameter of the pump and the minimum flow part of the impeller flow channel are
Same size. This ensures that the maximum particle solid substance in the pumped medium can pass smoothly, thereby achieving pump blockage free operation
Stuff effect. The biggest feature of this type of pump is that it can pump large pieces of ore, which contain weeds, wheat ears, straw, and other large particles
Measure wastewater containing fibrous substances without causing blockage. When used as a chemical process pump, it will not crystallize due to being pumped liquid
And blockage. If used for pumping fish and shrimp, it can ensure that the fish and shrimp are not twisted or broken by the impeller. So, WW type non clogging sewage treatment
The material pump is an ideal high-performance impurity pump.
The shaft seal of the WW type non clogging sewage pump adopts a packing box that is flushed with external water supply and sealed with soft packing. When used for pumping
When delivering corrosive liquids, mechanical seals can be used and a water cooling system can be installed. The pump and motor are connected by elastic couplings.
The performance range of WW type non clogging sewage pump is: flow rate (Q) is 20~500m3/h; The head (H) is 5-30m. At present, it is widely used in industrial sectors such as metallurgy, mining, coal, electricity, petroleum, chemical industry, urban sewage treatment, port and river dredging, and other operations.
