submersible sludge pump for wastewater treatment systems

Its basic working principle is to utilize the motor to drive the impeller to rotate, generating centrifugal force to draw in and discharge the liquid and the solid particles in it from the pump body. The following is a detailed description of its working principle:

submersible sludge pump Working principle:

1. Motor drive: submerged sludge pump adopts electric motor as the driving source, the motor is usually squirrel cage induction motor, which has high durability and reliability. The motor is driven by the power supply and rotates to drive the impeller in the pump body.
2. Impeller rotation generates centrifugal force: the impeller in the pump body rotates under the drive of the motor. Through the rotation of the impeller, centrifugal force is generated inside the pump, attracting the liquid and the solid particles therein into the pump body.
3. Liquid flow and solid particles through: centrifugal force will be the liquid and solid particles pushed to the pump’s drain. Under the wide flow channel and special impeller structure designed in the pump, solid particles can pass through easily to avoid the pump body being blocked.
4. Liquid discharge: When the liquid flows through the impeller, the kinetic energy is converted into the flow rate of the liquid, and the liquid is discharged through the drainage pipe of the pump to complete the discharge of sewage or sludge.
5. Seal protection: In order to ensure that the motor will not come into contact with the sewage, the submersible pump uses a highly efficient mechanical sealing system. It usually adopts double mechanical seal design, which can effectively prevent the liquid from entering the motor through the seals, and protect the long-term operation of the pump.

submersible sludge pump Features:

1. Motor: squirrel cage induction motor, class F insulation, protection grade IP68.
2. Non-obstructing impeller: the impeller designed with the latest non-obstructing theory, with wide flow channel, smooth water flow, easy passage of dirt and high efficiency. All impellers are corrected by dynamic and static balancing, reducing vibration and noise, smooth operation and long life.
3. Mechanical seal: the role of mechanical seal is to block the pumping medium in the motor part of the contact, double mechanical seals in series work independently of each other, to provide double protection for the motor.
4. Automatic landing off device (optional equipment): so that the pump installation, maintenance, repair quickly and easily, without the need to remove the barrel tank sewage.
5. Leakage detector: installed in the oil chamber leakage detector, can detect leakage caused by poor sealing or mechanical seal damage (less than 15kw, optional.). Greater than or equal to 15kw, standard equipment). High-power pumps in the junction box and the motor cavity installed leak detector, can be the junction box and the motor cavity leakage alarm signal, so that the control system to protect the pump (non-standard equipment, greater than or equal to 132kw can be optional).
6. Overheating protector: in the motor, add overheating protector, overload, temperature rise and other conditions are automatically detected, to avoid motor overheating caused by motor burnout (less than 15kw optional equipment, greater than or equal to 15kw standard equipment). Add overheating protector in the bearing, when the bearing temperature rises to the disconnection temperature, the protector automatically cut off the power supply, play a role in protecting the bearings (non-standard equipment, greater than or equal to 18.5kw can be optional).
7. Water-cooled jacket (optional equipment): when the pump is working, the pressure in the pump cavity is used to make the liquid continuously enter the space between the water-cooled jacket and the motor shell, to take away the heat generated by the motor, so as to ensure that the pump works normally at low water level (greater than or equal to 18.5kw can be equipped with options).

submersible sludge pump Uses:

1. Wastewater lifting station: used to lift municipal or industrial wastewater from a low place to the treatment plant or discharge system, to ensure that wastewater can flow smoothly.
2. Municipal wastewater treatment plant: in the process of urban wastewater treatment, used for sludge pumping and sewage from water treatment facilities.
3. First floor septic tank drainage system: used for discharging sewage from septic tanks to ensure hygiene and environmental cleanliness in residential areas.
4. Agricultural and animal husbandry wastewater treatment system: to treat wastewater and sewage produced by agricultural farming and help purify water resources in farms.
5. Hospitals, schools, communities and other living wastewater treatment system: used to treat the living sewage produced by hospitals, schools and communities, etc., to ensure the discharge of sewage in daily life.
6. Food, paper, mining, textile, leather, chemical plants and other industrial water treatment systems: in various industrial production processes, immersed sludge pumps are used to treat production wastewater, cleaning liquids, etc., to help treat and recycle water resources.
7. Water purification treatment system: used in water purification facilities, such as water plants, to help remove sludge, solids in the water, to ensure the purification of water quality.
