Submersible wastewater pump
1.Description - Submersible Sewage Pump
ASW submersible sewage pump(hereinafter as pump) is made up of motor, mechanical seal, pump and
stirring structure,etc, pump coaxial integrated design, is manufactured based on absorbing domestic and foreign advanced technology and advantages. Because of its auto-stirring function, the sewage discharge can be pumped smoothly. At the bottom of the pump chassis, there is a suction water device, which will run with high speed with the motor to lead the water out of the pump, at the same time, it washes the pond bottom with the speed 10-20m/s.

2.Application- Submersible Sewage Pump
ASW series submersible sewage pump is mainly used for municipal works, industrial buildings, hotels, hospitals, civil air defence, mines etc. Trades to drain off the sewage, waste water, rainwater and living water in cities containing Solid grains and various long fabrics.

3.Structure-Submersible Sewage Pump
1)Bearing:
SKF ,NTN bearing,Or HRB,ZWZ, LYC China famous bearing resonable configuration, can extend the duration of the pump.
2)Cooling:
The buit-in cooling system can have the pump normally work whether the motor is on or under the liquid surface. A part of the liquid is extracted to bring out the beat produced by the motor from the pump circulation to the cooling barrel and to the pump casing and, when external cooling is required, the cooling sleev e may be separated from the pump casing and individually connected to the cooling system.
3)Motor:
o Of F class insulation, max. working temperatures 155 C, and of a protective grade IPX8 with the effective seal.
Mechanical seal
Adopt the China famous brand Mecheanical seal, two ways of the seal are in series with each other and individually work to separate the motor from the pump seal to provide the motor with a dual protection The sealing material on the pump side is tungste n carbide tungsten carbide while on the motor side, graphite/silicon carbide. Oil chamber: Oil can lubricate and cool the mechanical seal and realize the attached function of safety by preventing liquid from penetrating into the motor. The air of a certain amount left indide of the chamber can lower the pressure accumulatively raised.
4)Impeller:
With the optimized design, the impeller wil not be blocked up when to transport liquid with its optimum flow and rate and the maximum efficiency. There are suitable impellers at choice for every point of working condition. There are single-geat, dual-geat and three-blade impellers available at choice per the medium to be extracted
Pump casing:
Use the know-how of CAD/CAM to make it of max. Efficiency and min wearability.
5)Shaft:
The pump is coaxial with the motor and the sealing device on the end of the shaft preven ts against contacting with the medium to protect is from corrosion.
The as short as possible designed stretched rotating shaft can be reduced with its deflection and vibration, extend the duration of both mechanical seal and bearing and lower the noise at running.
Monitor system:
Inside of the stator there are three inlaid series heat-control switches, which are in the state of "N.O." at the normal temperature and opened when the temperature on the stator gets to 125 . A water leakage probe is mounted inside the oil chamber to check water leakage and it will give a warning signal(the indicator lights), when the mechanical seal on the pump side leaks and the oil-water ratio in the oil chamber reaches a certain concentration, to automatic ally cut off the power to stop the work of the pump. Serviceman should replace the oil timely and check the mechanical
seal on the pump side and replace it it necessary. All the wiring box of the motor with a power not lower than 30kW is mounted with a leakage probe to check if a leak
with the cable seal.
6)Float switch:
The float switch will give a warning sigual(the indicator lights), when leakage occurs on the mechanical seal on the motor side, the liquid goes into the switch room and reaches a certain height, to stop the pump. Serviceman should check the mechanical seal and replace it if necessary. The function to check if the motor lack of phase is available with the electric control cabinet so as to prevent it from
burning due any lack of phase.
