1、 Overview of JPWQ stainless steel mixing sewage pump:

JYWQ and JPWQ series automatic mixing sewage pumps use automatic mixing devices on the basis of ordinary sewage pumps. This device rotates with the motor shaft to generate * mixing force, mixing the sediment in the sewage pool into suspended solids, and sucking them into the pump for discharge, which improves the anti blocking and sewage discharge capabilities of the pumps, completes drainage, cleaning and desilting at one time, and saves operating costs. It is an environmental protection product with obvious progressiveness and practicality.

2、 JPWQ stainless steel automatic mixing sewage pump usage range:
1. The discharge of severely polluted wastewater from factories and businesses.
2. The drainage system of urban sewage treatment plants, hospitals, and hotels.
3. Sewage drainage stations in residential areas.
4. The drainage station of the civil air defense system and the water supply device of the water plant.
5. Municipal engineering and construction sites.
6. Exploration, mining, and power plant supporting equipment.
7. Rural biogas digesters, farmland irrigation, and dredging of rivers and ponds.
JPWQ stainless steel automatic mixing sewage pump usage conditions:
1. The medium temperature shall not exceed 60 ℃, the medium density shall not exceed 1.3kg/L, and the liquid pH value shall be within the range of 4-10.
2. 1Cr18Ni9ti stainless steel material is suitable for various corrosive media.

4、 Structural characteristics of JPWQ stainless steel automatic mixing sewage pump:
1. Adopting a double channel unobstructed impeller structure with *, it improves the flow and discharge capacity of sewage and pollutants.
2. The automatic mixing device generates a stirring force of *, which mixes the sediment in the pool into suspended solids and sucks them into the impeller for discharge, achieving the effect of dredging.
3. The partition divides the base into two parts, and mixing and water inlet do not affect each other.
4. The mechanical seal is a double-sided mechanical seal, which is kept in the oil chamber for a long time to ensure the safe and reliable operation of the water pump.
5. The fluid dynamic seal of the secondary impeller structure not only serves as an auxiliary seal to protect the mechanical seal, but also balances axial forces and extends the service life of the bearing.
6. There is a leakage detection probe installed in the pump wiring chamber. When leakage occurs, the probe sends a signal, and the control system implements protection for the pump. Equan Company can provide a fully automatic safety protection control cabinet.
7. The stator of the motor adopts B-level and F-level insulation, and is equipped with a thermal protector. When the motor is overloaded and heats up, the protector will act in a timely manner to protect the pump and motor.
8. There is an oil-water probe installed in the oil chamber. When the mechanical seal is damaged, water enters the oil chamber, the probe sends a signal, and the control system protects the water pump.
9. JPWQ is equipped with an internal circulation cooling system, which can ensure the normal operation of the water pump at the lowest water level in the pool.

7、 Usage and safety operating procedures:
1. Before operation, use a megohmmeter to check the insulation resistance of the motor stator winding to ground, which should not be less than 50 megohms.
2. Check for any damage or breakage of the cable. If there is any damage, it must be replaced in a timely manner to avoid electric leakage; The cable cross-section should match the current.
3. When the voltage exceeds ± 10% of the rated voltage, the electric pump shall not be started.
4. To ensure safe use, the grounding wire in the four core cable must be reliably grounded to prevent electric shock accidents.
5. When the electric pump is submerged in water, it should be lifted vertically and not allowed to be placed horizontally on the ground, let alone get stuck in sludge. When stopping use, the electric pump should be lifted and cleaned, placed in a dry place, and attention should be paid to antifreeze.
6. Do not use cables as installation lifting ropes.
7. Check the direction of rotor rotation, which should be clockwise when viewed from top to bottom.
8. Outdoor switches or grounding wire terminals should be protected from rain and moisture. It is forbidden to touch the switch when hands are wet or feet are bare to prevent electric shock.
9. When moving the electric pump, the power must be cut off, and people must not come into contact with the water source while the pump is running to prevent electric leakage and personal accidents.
10. It is strictly prohibited to operate the motor with a missing phase. If the fuse is found to be blown, the cause should be checked before continuing to use, and the fuse should not be thickened arbitrarily.
11. When the pump is running, there should be a dedicated person to manage it. If any abnormal phenomena are found, the machine should be stopped immediately for inspection and troubleshooting. (Refers to the situation where a fully automatic protection cabinet is not equipped).
12. After half a year of normal operation of the electric pump under the specified working medium conditions, the sealing condition of the oil chamber should be checked. If the oil in the oil chamber is emulsified or has water precipitation, the 10-20 # mechanical oil and mechanical seal should be replaced in a timely manner. For electric pumps used under harsh working conditions, regular maintenance should be carried out.
13. Users should choose the appropriate flow and head according to the actual operating conditions to achieve the desired effect. The parameters shown on the pump nameplate or instruction manual are the operating conditions of the pump. Users can choose to use it within (0.7-1.2) times the flow rate. Overloading the flow rate is prohibited, otherwise excessive flow and low lift can easily cause motor overload.

8、 Maintenance of stainless steel mixing sewage pump:

1. The electric pump should be managed and used by a dedicated person, and the insulation resistance between the pump winding and the casing should be checked regularly to ensure that it is normal.

2. After each use, especially for thicker and more viscous media, the electric pump should be run in clean water for several minutes to prevent sedimentation inside the pump and ensure its cleanliness.

3. After disassembling and repairing the electric pump, the casing components must undergo a 0.2MPA air pressure test to ensure reliable sealing of the motor and oil chamber.
