Various series of submersible slurry pumps, submersible slurry pumps, excavator slurry pumps

Description :

　　Various series of submersible slurry pumps, submersible slurry pumps, excavators, slurry pumps are electric machinery assembled from an electric motor and a pump immersed in water. This product is widely used in metallurgy, chemical industry, mining, coal, electricity, building materials, municipal environmental protection, and river dredging. River sand, gravel, coal slag, tailings, iron sand, mineral sand, and other liquids containing abrasive solid particles.

　　Various series of submersible slurry pumps, submersible slurry pumps, excavator slurry pumps, technical parameters:

　　Power: 3KW-132KW Flow: 10-2200m3/h

　　Head: 5-60m Speed: 1440r/min, 980r/min

　　Caliber: 50mm-300mm Temperature: -15 ℃ -+140 ℃

　　Particle size: within 5 centimeters Material: High wear-resistant alloy (Cr26)

　　structural characteristics

　　The entire machine is a dry pump, and the electric motor uses oil. Chamber sealing method. Mechanical seals can effectively prevent high-pressure water and impurities from entering the interior of the motor.

　　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 flow components such as impellers and stirring impellers are made of high hardness and high chromium cast steel, which has strong wear resistance, corrosion resistance, and high drainage capacity.

　　4. The motor can suck water without restriction, resulting in a high slag discharge rate and more thorough dredging.

　　5. Simplified the overall equipment and reduced the total investment per unit.

　　6. No need for auxiliary mixing or spraying devices, making the operation simpler.

　　7. The motor is submerged in water, eliminating the need for complex grounding protection and fixing devices, making management easier.

　　8. The stirring impeller directly contacts the sedimentary surface, and the concentration is controlled by the diving depth, making concentration control more flexible.

　　9. The equipment works directly underwater without noise and vibration, making the site cleaner.

　　When viewed from the drive end, the rotation direction of the pump is clockwise.

　　Installation and usage precautions:

　　Before starting, please carefully check whether the electric pump has been deformed or damaged during transportation, storage, and installation, and whether the fasteners have become loose or fallen off. 2. Check if the cable is damaged, broken, etc. If the cable is damaged, it needs to be replaced to avoid leakage.

　　3. Check if the power supply device is safe and reliable. The rated voltage must match the nameplate.

　　4. Use a megohmmeter to check the insulation resistance of the motor stator winding in cold state, which should not be less than 50M.

　　5. It is strictly prohibited to use pump cables as installation and lifting ropes to avoid danger.

　　When viewed from the inlet, the rotation direction of the pump is counterclockwise. If reversed, any two wires in the cable must be reversed to the connection position, and the pump can rotate forward.

　　7. The pump should be immersed vertically in water and should not be placed horizontally or sink into sludge. When the pump moves, the power must be cut off. After multiple uses of the electric pump, it must be placed in clean water for a few minutes to prevent sediment from remaining in the pump and to keep the electric pump clean.

　　When the pump is not used for a long time, the electric pump should be removed from the water to reduce the chance of damping the motor stator winding and increase the service life of the electric pump. Under normal working conditions, the electric pump should be maintained after one year of operation. Replace worn parts, check sealing, and replenish or replace bearing grease and insulation oil in the oil chamber to ensure the electric pump. The effect is very good.

　　Various series of submersible slurry pumps, submersible slurry pumps, excavator slurry pumps, and their usage conditions:

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

　　2. The high temperature of the medium shall not exceed 60 ℃, and the medium shall not contain flammable or explosive gases.

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

　　4. Diving depth for passengers: not more than 20 meters, not less than 1 meter.

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

　　Quality and after-sales service

　　1. Quality three guarantees, except for vulnerable parts.

　　2. The factory guarantees to provide customers with low-priced accessories for life.

　　3. Provide sufficient service for after-sales issues for cooperative units or individuals.
