★ Model Type: SWQ/SWBQ
★ SWQ and SWBQ series submersible sewage pumps have remarkable energy-saving effect,anti-winding,no clogging,automatic installation and automatic control,etc.,and have unique effects in discharging solid particles and long-fiber waste.
★ It can be installed in a small and simple pump station,and can be hidden underground without causing any obstacles.It can be quickly and easily lowered into the liquid along the guide rod.It is flexible to use and easy to assemble and disassemble.
★ It can automatically control the water level according to user requirements,and equipped with automatic protection devices and electrical control cabinets.Pumping medium(60°C).
New submersible sewage pump with automatic protection devices
1.An overheating protection element to prevent damage due to high temperature
2. A water leakage probe to monitor whether water is entering the pump cavity
3. A float switch to monitor mechanical seal failure and water ingress in the motor cavity
4. Bearing temperature protection, monitoring for excessive motor bearing temperatures.Model Meaning
Structures Description
Bearing:
Imported SKF of NTN bearing, which, with a reasonable configuration, can oxtend the duration of the pump.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 sleeve may be separated from the pump casing and in- dividually connected to the cooling system.Motor:
Of F class insulation, max. working temperatures 155℃, and of a protective grade IPX8 with the effective seal.Mechanical seal:
Use Bogman mechanical seal of Germany, 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 tungsten carbi- de/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 pen- etrating into the motor. The air of a certain amount left indide of the chamber can lower the pressure accumulatively raised.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. effi- ciency and min wearability.Monitor system:
Inside of the stator there are three inlaid series heat-con- trol 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 cer- tain concentration, to automatically 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.
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.
