Working principle
In addition to the main impeller, the bottom is also equipped with a stirring impeller. The motor shaft drives the water pump impeller and the stirring impeller to rotate at a high speed to transfer energy to the slurry medium, so that the sediment, sediment, and slurry are stirred evenly, and the pump is not in In the case of an auxiliary device, high-concentration conveyance is achieved.
In addition, for special conditions where the sediment is compacted or the sand layer is hard, and it cannot be completed only by the pump impeller and self-priming, two-sided and multilateral agitators (reamers) can be added to loosen the sediment and increase the extraction concentration. To achieve automatic hinge suction. It also prevents bulky solids from clogging the pump, allowing solids and liquids to be fully mixed for easier handling.
Pump over-flow material: normal configuration high chromium wear-resistant alloy（cr26）。
Others such as ordinary wear-resistant alloys, ordinary cast iron, cast steel, 304, 316, and 316L stainless steel, and duplex stainless steel can be customized according to different working conditions and customer requirements.

Installation method
The submersible sand pump produced by our company has a coaxial pump, compact structure, high efficiency, convenient installation and maintenance, economic operation, and strong adaptability. Its installation methods include mobile installation and fixed installation. Fixed installation is divided into automatic Coupling installation and fixed dry installation, mobile installation is also called free installation.
Mobile installation method The electric pump is supported by a bracket, and the water outlet hose can be connected. Suitable for river treatment, industrial sewage discharge, pumping of municipal construction sludge and other occasions.
Automatic coupling installation
The automatic coupling installation device can quickly and easily put the electric pump into the sand medium along the sliding guide rail, and the pump and the base are automatically coupled and sealed. Installation and maintenance are very convenient.
In this type of installation, the pump is connected to the coupling device, and the coupling base is fixed to the bottom of the pump pit (when the sewage pit is built, the anchor bolts are embedded and the coupling base can be fixed when in use). It moves up and down automatically. When the pump is lowered, the coupling device is automatically coupled with the coupling base, and when the pump is lifted, it is automatically disconnected from the coupling base.
This way can be equipped with hydraulic switches, intermediate terminal boxes and fully automatic protection control cabinets according to user requirements. In the selection, the pump model, installation method, tank depth, and pump control protection method should be indicated in order to provide the optimal system. If users have special needs, our factory can provide pumps with special materials.
Fixed dry installation
The pump device is on the other side of the pump pit and is fixed on the base together with the water inlet pipe. Thanks to the water jacket cooling system, the pump can be guaranteed to run at full load. Advantages: The continuous impact of the water flow on the puddle does not damage the pump and can withstand accidental flooding. Suitable for municipal construction, sewage sludge discharge from underground pumping station ofoverpass.

Notes for use:
1. Before starting, carefully check whether the electric pump is deformed or damaged during transportation, storage and installation, and whether the fasteners are loose or falling off;
2. Check the cable for damage, breakage and other phenomena. If it is damaged, it must be replaced to avoid leakage;
3. Check whether the power supply is safe and reliable. The rated voltage must match the nameplate.
4. Use a megohmmeter to check the cold state insulation resistance of the stator winding of the motor must not be less than 50MΩ;
5. It is strictly forbidden to use the cable of the pump as the installation and lifting rope to avoid danger;
6. The rotation direction of the pump is counterclockwise when viewed from the water inlet. If it is reversed, any two wires in the cable must be reversed for the connection position, and the pump can rotate forward.
7. The pump should be submerged into the water vertically. It should not be placed horizontally or trapped in sludge. When the pump is transferred, the power must be cut off.
8. Before the electric pump is stopped, it must be put into clean water for several minutes to prevent the sediment from being left in the pump and ensure that the electric pump is clean;
9. When the electric pump is not used for a long time, it should be taken out of the water to reduce the chance of damping the stator winding of the motor and increase the service life of the electric pump;
10. Under normal working conditions, after the electric pump has been working for half a year (it can be advanced to three months if the work intensity is large), maintenance should be performed, worn and worn parts should be replaced, the tightening status should be checked, and bearing grease should be replenished or replaced. And insulating oil in the oil chamber to ensure the good operation of the electric pump;
11. When the water depth exceeds 20 meters, it is recommended that the cables be tied with floats at an interval of 1 meter. When the water pump is running, the cables are broken. When the water is transported over long distances, the water pipes are tied with floats at a distance of 5 meters to facilitate movement.
