Submersible sewage pump

Submersible sewage pump is a submersible sewage pump, especially suitable for conveying liquids containing hard solids and fibers, as well as particularly dirty, sticky and slippery liquids. Compared with the general horizontal pump or vertical sewage pump, submersible sewage pump obviously has the following advantages: compact structure, small footprint; easy installation and maintenance; long continuous operation time; no cavitation damage and irrigation and diversion problems

Product overview

★Model: SWQ/SWBQ

★SWQ, SWBQ series submersible sewage pump has the characteristics of remarkable energy saving effect, anti winding, no clogging, automatic installation, automatic control, etc., and has a unique effect on the discharge of solid particles and long fiber waste.

★Can be installed in a small simple pumping station, can be hidden underground, does not cause any obstacles, can be quickly and easily sunk into the liquid along the guide rod, flexible use, easy to assemble and disassemble.

★The water level can be automatically controlled according to user requirements, and is equipped with automatic protection devices and electrical control cabinets. Transport medium (60 ℃).

★New automatic protection device for submersible sewage pump
1. Overheat protection element to prevent high temperature damage
2. Water leakage probe to monitor whether there is water in the pump cavity
3. Floating switch, monitoring mechanical seal failure and motor cavity water
4. Bearing temperature protection, monitoring motor bearing temperature is too high

Product use

1. Buildings, ditches, dams, tunnels and land drainage.

2. Draining and discharging of raw water, mixed water, natural sewage and mud water.

3. Treatment and extraction of sewage sediment recycling fluid and garbage.

4. Pumping, irrigation and drainage, surface treatment, water source protection, water level control in open pit mining.

Working conditions

Model meaning

Structure Description

★Bearing:
Imported SKF, NTN bearings, reasonable configuration, can extend the service life of the pump.

★Cooling:
Built-in cooling system, whether the motor is above or below the liquid level, can ensure the normal operation of the pump. A portion of the liquid is extracted to draw the vibration generated by the motor from the pump cycle to the cooling cylinder and pump housing. When external cooling is required, the cooling jacket can be separated from the pump housing and connected to the cooling system separately.

★Motor:
Class F insulation, maximum working temperature 155 ℃, protection grade IPX8, good sealing effect.

★Mechanical seal:
The German Bogman mechanical seal is adopted, and the two-way seals are connected in series and work separately to isolate the motor from the pump seal and provide double protection for the motor.
The pump side sealing material is tungsten carbide/tungsten carbide, and the motor side sealing material is graphite/silicon carbide.

★Oil room:
The oil lubricates and cools the mechanical seal and prevents liquid from penetrating into the motor for additional safety. A certain amount of air is left in the oil chamber to reduce the accumulated elevated pressure.

★Impeller:
After optimized design, the impeller will not be blocked when conveying liquid, has the best flow and speed, and has the highest efficiency. Each working condition has a suitable impeller to choose from.
According to the extracted medium, there are single-leaf, double-leaf and three-leaf impellers to choose from.

★Pump casing:
Using CAD/CAM technology, the highest efficiency and minimum wear.

★Monitoring system:
Three series thermal control switches are embedded in the stator, which are in a "normally open" state at normal temperature and open when the stator temperature reaches 125°C.
The oil chamber is equipped with a water leakage probe to detect water leakage. When the mechanical seal on the pump side leaks and the oil-water ratio in the oil chamber reaches a certain concentration, an alarm signal (indicator light) will be issued to automatically cut off the power supply and stop the pump.

The maintenance personnel should replace the lubricating oil in time, check the mechanical seal on the pump side, and replace it if necessary.

Motor junction boxes of 30kW and above are equipped with water leakage probes to check whether the cable seal is leaking.,

★float switch:
When the mechanical seal on the motor side leaks, the liquid enters the switch chamber and reaches a certain height, and the float switch will issue a warning signal (the indicator light is on).

Installation method

WQ submersible sewage pump a total of 5 kinds of installation, as follows:

1, automatic coupling installation

The pump is lowered along the guide rod and automatically connected to the discharge pipe system. Installation and construction costs are minimal and maintenance costs are reduced.

2, mobile hard pipe installation

The pump is supported by its base, and the hard pipe joint is connected to the pipeline system.

3, mobile hose installation

The pump is supported by its base, and the hose connector is connected with the water outlet hose. It is multi-purpose and easy to install. The pump can be easily moved from one sewage well to another.

4, fixed dry installation

Can withstand flooding, for wet/dry well or pipeline connection of the pump system, suction port and drain port a flange and pipe connection, vertical installation. If this installation is selected, it must be equipped with a cooling system.

5, fixed wet installation

The pump is supported by a base and fixed at the bottom of the sewage well. The drain port is connected with the pipeline and installed vertically.
