Anaerobic tank sludge reflux pump

Construction and working principle Anaerobic tank sludge reflux pumpTerms of Use
The submersible sludge reflux pump consists of an impeller, submersible motor, guide cover, through wall pipe, flap door, installation of lifting guide rod, lifting steel rope, underwater cable, lifting bracket and hand-operated lifting device, angle steering device, local control cabinet, etc.
The submersible sludge reflux pump can rotate and balance freely without any jamming, stagnation, vibration, or other phenomena;
Conduct a sealing pressure experiment on a submersible sludge reflux pump with a pressure of 0.3 MPa for 5 minutes without any leakage;
4. Adopting a dual mechanical seal structure and a lip seal to form a dynamic sealing system, the mechanical seal ensures reliable operation within 25000 hours without the need for replacement;
5. It can work continuously under the conditions of full immersion and submerged motor exposed to the liquid surface, while ensuring that it can still operate normally once turned on, even in the case of intermittent operation and long-term shutdown.
6. The outgoing cable adopts YZW type rubber sheathed flexible cable in GB5013.2 or other cables with the same performance. The standard configuration length for a single unit is 10m. The cable sealing head is treated with special vulcanization to prevent damage to the cable sheath and water leakage to the motor;
Its surface is bright and free from stains, bumps, cracks, and other phenomena;
There is sufficient space in the oil chamber to accommodate expansion caused by temperature differences, and a sealed leakage protection device is installed;
The two-color wire (yellow/green) in the 9-out cable is designated as the grounding wire, and the connection is reliable. The grounding sign is obvious and not easily erased during the service life;
10 impellers and rotors undergo dynamic balancing tests, with a balancing accuracy of G6.3;
There are thermal protection switches installed inside the stator winding and at the positions of the upper and lower bearings, and a sealed leakage protection device is installed inside the stator cavity.
Installing guide rods can ensure the free rotation, lifting, and adjustment of various angles of the equipment, and there is no need to empty the pool when lifting and installing the mixer.

Product StructureAnaerobic tank sludge reflux pumpTerms of Use

This mainly consists of the host, installation system, and electrical control equipment. The host is mainly composed of impellers, submersible motors, reverse flow cylinders, guide pulleys, etc. The impeller is directly mounted on the motor shaft, while the submersible motor is fixed inside the guide cylinder.

Product installation:

1. Proper installation and use are the basic guarantees for the long-term and normal operation of the pump
2. The digestive fluid submersible reflux pump adopts an automatic coupling installation system, which can quickly replace the pump for inspection without any mechanical disassembly, making it convenient and fast
3. The through wall pipe of the digestive fluid submersible reflux pump needs to be pre embedded, and the guide rod and lifting device should be connected to the tank body with expansion bolts, without the need for pre embedded parts.

When lifting the reflux pump, the lifting ring chain must not be tangled, and the chain groove of the chain hoist must face the lifting person.

The fixed position of the cable should be moderate, neither too tight in the hand and damaging the cable, nor too tight in the hand and causing the cable to be wrapped in the impeller and damaged.
