The ZJQ submersible sand suction pump has its motor and water pump operating underwater coaxially. The flow-through components of this pump are made of high-chromium alloy wear-resistant materials, which endow it with good wear resistance and a large flow passage. It is suitable for transporting media such as sand and sediment containing relatively large solid particles, ore pulp, coal pulp, and sand and gravel... This series of products is designed and manufactured by absorbing advanced technologies. The unique sealing device can effectively balance the pressure inside and outside the oil chamber, maximizing the protection of the reliability of the mechanical seal. The motor is equipped with multiple protection measures such as overheating protection and water inlet detection protection, enabling it to operate safely for a long time under harsh working conditions. The front mixing impeller of the water pump can impact the deposited sediment into a high-concentration turbulent flow, allowing the water pump to achieve high-concentration sediment suction without the need for auxiliary devices.

II. Product Features

1. The whole machine is of the dry type with the pump at the lower part. The motor adopts the oil chamber sealing method, and a mechanical seal is installed inside, which can effectively prevent high-pressure water and impurities from entering the inner cavity of the motor.

2. In addition to the main impeller, there is also a mixing impeller, which can stir the sediment deposited at the bottom of the water into a turbulent flow and then pump it out.

3. The flow-through components such as the impeller and the mixing impeller are made of high-hardness high-chromium cast steel, which is wear-resistant, corrosion-resistant, and has strong sewage discharge capacity, and can pass through relatively large solid particles.

4. Since the motor is submerged underwater, it is not restricted by the suction head, with a high slag suction rate and more thorough sediment removal.

5. The overall equipment is simplified, and the total investment of the unit is reduced.

III. Usage Conditions

1. The power supply is a 50HZ/380V three-phase AC power supply.

2. The maximum temperature of the medium shall not be higher than 60°C, and the medium does not contain flammable and explosive gases.

3. The maximum weight concentration of solid particles in the medium: 45% for ash slag and 60% for slag.

4. The submergence depth of the unit: not more than 20 meters and not less than [a certain value] meters.

5. The working position of the unit in the medium is vertical, and the working state is continuous.

Maintenance and Upkeep

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

2. After each use, especially when dealing with relatively thick and viscous slurries, the electric pump should be operated in clean water for several minutes to prevent sediments from remaining inside the pump and ensure the cleanliness of the electric pump.

3. If the electric pump is not used for a long time, it should be taken out of the water and not be soaked in water for a long time to reduce the chance of the motor stator winding getting damp and increase the service life of the electric pump.

4. Under normal conditions, after the pump is used for 300 to 500 hours, the oil in the oil chamber (No. 10 to 30 engine oil) should be added or replaced to keep the mechanical seal in a good lubrication state and improve the service life of the mechanical seal.

5. After the electric pump is disassembled and repaired, the casing assembly must be inspected through an airtight test with a pressure of 0.2Mpa to ensure the reliable sealing of the motor.

6. The sealing ring between the impeller and the pump body has a sealing function. If the seal is damaged, it will directly affect the performance of the pump, and it should be replaced when necessary.

Please note that in the text above, where it says "not less than [a certain value] meters", you need to fill in the specific minimum submergence depth value according to the actual situation. If you want to translate this text into other languages or have other requirements, you can continue to ask me.
