Jywq Automatic Mixing Sewage Pump

JYWQ automatic mixing sewage pump adopts an automatic stirring device based on the ordinary sewage pump. The device rotates with the motor shaft and generates a strong stirring force to stir the sediment in the sewage pool into suspended matter, which is then sucked into the pump and discharged. The anti-blocking and sewage discharge capabilities of the pump are improved, and drainage, sewage cleaning, and silt removal are completed in one go, saving operating costs.

Commonly used models are: JYWQ50-12-15-1200-1.5, JYWQ50-15-15-1200-2.2, JYWQ50-20-15-1200-2.2, JYWQ50-40-15-1400-4, JYWQ65-37-13- 1400-3, JYWQ50-40-30-1600-7.5, JYWQ80-40-7-1600-2.2, JYWQ80-43-13-1600-4, JYWQ100-80-9-2000-4, JYWQ100-80-9- 2000-4, JYWQ150-150-10-2000-7.5, JYWQ150-180-22-2600-18.5 and other series

 The WQK belt cutting device sewage pump Scope of application 

JYWQ automatic mixing sewage pumpadvantage:

1. Use the water pressure of the pump itself to stir the precipitated sludge in the sewage tank evenly to truly achieve the purpose of discharging the sediment in the sewage tank.

2. The large flow channel anti-clogging hydraulic component design greatly improves the dirt passing capacity, and can effectively pass through 5 times the fiber material of the pump diameter and solid particles with a diameter of about 50% of the pump diameter.

3. Reasonable design, reasonable matching motor, high efficiency, and significant energy saving effect.

4. The mechanical seal adopts double-pass series sealing, made of hard corrosion-resistant tungsten carbide, which is durable and wear-resistant, allowing the pump to operate safely and continuously for more than 8,000 hours.

5. The pump has a compact structure, small size, is easy to move, and is easy to install. There is no need to build a pump room and it can work when submerged in water, reducing project costs.

6. There is an oil and water probe in the oil chamber to provide absolute protection for the pump.

7. It can be equipped with a fully automatic safety protection control cabinet to protect the pump from water leakage, electric leakage, overload and overtemperature, etc., to improve the safety and reliability of the product.

8. The float switch can automatically control the stop and start of the pump according to the required water level changes, without the need for special supervision.

9. The motor can adopt a water jacket type external circulation cooling system to ensure the safe operation of the electric pump in a waterless (dry) state.

10. The double guide rail automatic coupling installation system brings great convenience to the installation and maintenance of the pump, and people do not need to enter the sewage pit for this purpose.

11. There are two installation methods: fixed automatic coupling installation and mobile free installation, which can meet different usage occasions.

JYWQ automatic mixing sewage pump Conditions of Use

A. The medium temperature does not exceed 60ºC, and the medium weight is 1~1.3kg/dm3.

B. For pumps without internal gravity circulation cooling system, the motor part shall not expose more than ½ of the liquid level.

C. The usage range of cast iron material is PH5~9.

D. 1Cr18Ni9Ti stainless steel material can be used in various corrosive media.

Flow range (Q): 12~1800m3/h cubic meters/hour

Lift range (H): 7~60m

Speed (r/min): 450~2900r/min rpm

JYWQ automatic mixing sewage pump maintenance

1. The electric pump should be managed and used by dedicated personnel, and the insulation resistance between the electric pump winding and the casing should be checked regularly to see if it is normal.

2. After each use, especially after use in thicker and more viscous media, the electric pump should be placed in clean water and run for a few minutes to prevent sediment from remaining in the pump and ensure the cleanliness of the electric pump.

3. After the pump is disassembled and repaired, the casing components must undergo a 0.2MPa air pressure test to ensure that the motor and oil chamber are sealed reliably.

JYWQ automatic mixing sewage pump  Usage methods and safe operating procedures

1. Before operation, use a megohmmeter to check the insulation resistance of the motor stator winding to ground. The minimum should not be less than 50 megohms.

2. Check whether the cable is damaged or broken. If damaged, it must be replaced in time to avoid leakage; the cable cross-section should match the current.

3. When the voltage exceeds ±10% of the rated voltage, the electric pump must not be started.

4. To ensure safe use, the ground 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. It is not allowed to be placed horizontally on the ground, let alone fall into the sludge. When stopping use, the electric pump should be hoisted, cleaned, placed in a dry place, and protected from freezing.

6. Prohibited: Use the cable as an installation lifting rope.

7. Check the rotation direction of the rotor. It should rotate clockwise when viewed from top to bottom.

8. Outdoor switches or terminals should be protected from rain and moisture. It is prohibited to touch the switch with wet hands or bare feet to prevent electric shock.

9. When moving the electric pump, the power supply must be cut off. People are not allowed to touch the water source when the electric pump is running to prevent personal accidents caused by leakage of electricity.

10. It is strictly forbidden to operate the motor with phase loss. If the fuse is found to be blown, the cause should be checked before continued use. Do not make the fuse arbitrarily thick.

11. When the pump is running, it should be managed by a dedicated person. If any abnormality is found, it should be stopped immediately for inspection and troubleshooting. (Refers to the situation without a fully automatic protection cabinet>.

12. After the electric pump has been operating normally for half a year under the specified working medium conditions, the sealing condition of the oil chamber should be checked. If the oil in the oil chamber is milky or there is water precipitation, the No. 10 to No. 20 mechanical oil and mechanical seal should be replaced in time. For electric pumps used under harsh working conditions, they should be inspected frequently.

Principles for selecting sewage pumps - DFIN Pump Industry

1. High mechanical reliability, low noise, and minimal vibration.

2. Economically, it is necessary to comprehensively consider the total cost of equipment, operation, maintenance, and management fees to minimize them.

3. Make the selected pump type and performance meet the requirements of process parameters such as device flow rate, head, pressure, temperature, cavitation flow rate, and suction stroke.

4. Must meet the requirements of medium characteristics.

For pumps that transport flammable, explosive, toxic, or valuable media, reliable shaft seals or leak free pumps are required, such as magnetic drive pumps, diaphragm pumps, and shielded pumps

For pumps transporting corrosive media, it is required that the convection components use corrosion-resistant materials, such as AFB stainless steel corrosion-resistant pumps and CQF engineering plastic magnetic drive pumps.

For pumps transporting media containing solid particles, it is required that the convection components be made of wear-resistant materials, and if necessary, the shaft seal should be flushed with clean liquid.
