The ZJQ submersible sand suction pump operates coaxially with the motor and water pump when submerged in water. The flow components of the pump are made of high network alloy wear-resistant materials, which have good wear resistance and a large flow channel. It is suitable for transporting media such as sediment, slurry, coal slurry, sand and gravel containing large solid particles This series of products absorbs advanced technology design and manufacturing from both domestic and foreign sources. The unique sealing device can effectively balance the pressure inside and outside the oil chamber, maximizing the reliability of the mechanical seal. The motor adopts various protection measures such as overheating protection and water inlet detection protection, and can operate safely for a long time under harsh working conditions. The pre mixing impeller of the water pump can impact the sediment into high concentration turbulence, enabling the water pump to achieve high concentration suction without the need for auxiliary devices.
2、 Product features:
1. The whole machine is a dry bottom pump type, and the motor adopts an oil chamber sealing method with a mechanical seal inside, which can effectively prevent high-pressure water and impurities from entering the motor cavity.
In addition to the main impeller, there is also a stirring impeller that can stir the sediment deposited on the bottom of the water into turbulence and extract it.
3. The impeller and mixing impeller are made of high hardness and high network cast steel, which is wear-resistant, corrosion-resistant, and has strong drainage ability. They can pass through larger solid particles
4. The motor is submerged underwater without being limited by suction, with a high slag absorption rate and more thorough dredging. 5. The overall equipment is simplified, and the total investment of the unit is reduced.
III Usage conditions:
1. The power supply is 50HZ/380V three-phase AC power supply.
2. The maximum temperature of the medium shall not exceed 60 ℃, and the medium shall not contain flammable or explosive gases.
3. The maximum weight concentration of solid particles in the medium is 45% for ash and 60% for slag.
4. Diving depth of the crew: not more than 20 meters, not less than one meter.
5. The working position of the unit in the medium is vertical, and the working state is continuous.
maintenance
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, which is particularly suitable for thick and viscous slurries, the electric pump should be placed in clean water and run for several minutes to prevent sedimentation inside the pump and ensure its cleanliness.
3. If the electric pump is not used for a long time, it should be removed from the water and not soaked in bubbles for a long time to reduce the chance of moisture in the motor stator winding and increase the service life of the electric pump.
4. Under normal conditions, the pump should be filled or replaced with oil (10-30 octane oil) in the oil chamber every 300-500 hours of use to maintain good lubrication of the mechanical seal and improve its service life.
5. After disassembling and repairing the electric pump, the casing components must undergo a 0.2Mpa air tightness test to ensure reliable motor sealing.
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 should be replaced if necessary.
