YW Submerged Sewage Pump Product Overview:

The YW type submersible sewage pump is a new generation of pump products developed based on the introduction of foreign * technology and combined with the characteristics of domestic water pump usage. It has the features of energy saving *, anti winding, no blockage, automatic installation and automatic control. It has unique advantages in the disposal of solid particles and long fiber waste.
This series of pumps adopts an impeller structure and a new mechanical seal, which can effectively transport solids and long fibers. Compared with traditional impellers, the impeller of this pump adopts a single channel or double channel form, which is similar to a curved pipe with the same cross-sectional size and has very good flow characteristics. Coupled with a reasonable volute chamber, the pump has high efficiency and the impeller has undergone dynamic and static balance tests, making the pump operate without vibration.

Model meaning of YW type submersible sewage pump:

YW type submersible sewage pump usage conditions:

1. The operating environment temperature of the pump is ≤ 40 ℃, and the humidity is ≤ 95%; Altitude ≤ 1000 meters.
2. The medium temperature shall not exceed 60 ℃, and the medium density shall be 1-1.3kg/dm3.
3. The range of use for cast iron material is from pH 5 to 9.
4. Stainless steel material can be used with general corrosive media.
5. The altitude of the usage environment should not exceed 1000 meters. If it exceeds the above conditions, it should be mentioned when placing an order to provide you with more reliable products.
Note: If the user has special requirements for temperature, medium, etc., please specify the detailed information of the conveying medium when ordering, so that our unit can provide more reliable products.

Product features of YW type submersible sewage pump:

1. The use of a single or double blade impeller structure greatly improves the ability of pollutants to pass through, effectively passing through 5 times the fiber material of the pump diameter and solid particles with a diameter of about 50% of the pump diameter.
2. The mechanical seal adopts a new type of hard and corrosion-resistant titanium tungsten material, which can ensure the safe and continuous operation of the pump for more than 8000 hours.
3. The overall structure is compact, small in size, low in noise, energy-saving *, easy to maintain, no need to build a pump room, and can work underwater, greatly reducing project costs.
4. The pump has a compact structure, small volume, easy movement, and simple installation.
5. It can be equipped with a liquid level automatic control cabinet, which can automatically control the start and stop of the pump according to the required liquid level changes, without the need for special supervision, making it extremely convenient to use.
6. The pump is a vertical structure, and the pump body is immersed in liquid during operation, making it easy to start. There is no problem of exhaust and evacuation, and it has the characteristics of no leakage. The underwater depth can reach 7 meters.
7. The shaft connection structure is reliable, and the pump and motor are connected by a coupling. The pump shaft size is precise, ensuring smooth operation of the pump with sufficient safety factor.
8. There are two types of pumps: single tube installation and double tube installation. The supporting components include disc and square disc installation, which are suitable for different needs.

Precautions for YW type submersible sewage pump:

Before using the pump, carefully inspect the pump and motor for any damage Check the tightness of fasteners.
2. Check for any friction sound when turning the pump Simultaneously check the concentricity between the pump shaft and the motor shaft The deviation of the outer circle of the two couplings shall not exceed 0.5mm
3. Connect the pipeline to the pump outlet A separate bracket should be installed It is not allowed to add its weight to the pump body.
4. Unless otherwise specified, the water pump must be equipped with a fully automatic water pump control cabinet Do not directly connect to the power grid or use a knife switch to connect the current Ensure the normal operation of the water pump
5. Do not operate the water pump in a low head state (generally using a head not less than 60% of the rated head) Can be controlled within the recommended head range The motor of the waterproof pump was burned out due to overload

Maintenance and upkeep of YW type submersible sewage pump:

1. The water pump should be managed and used by a dedicated person Regularly check the circuit and operation of the water pump.
2. After each use, especially for thicker and more viscous slurries The water pump should be placed in the cooling water and run for several minutes Prevent sedimentation inside the pump Ensure the cleanliness of the water pump.
3. Under normal conditions The pump should be filled or replaced with oil (10-30 # oil) in the oil chamber every 300-500 hours of use Keep the mechanical seal in good lubrication condition Improve the service life of mechanical seals.
The sealing ring between the impeller and the pump body has a sealing function If the sealing ring is damaged, it will directly affect the performance of the pump If necessary, it should be replaced.

【 YW type submersible sewage pump 】 Fault causes and troubleshooting methods:

Fault phenomenon

Root cause analysis

exclusion method

Insufficient flow or no water output

1. Impeller rotation error

2. Whether the valve is open and intact

3. The impeller of the pipeline is blocked

4. Low speed

5. High head

6. High density and precision of the pumping medium

7. Damaged sealing ring (at the mouth ring)

1. Adjust the rotation direction of the impeller

2. Inspection, maintenance, and elimination

3. Clean up debris

4. Check electrical equipment and circuits

5. Change the pump or reduce the head

6. Dilute with water to reduce concentration and viscosity

7. Replacement

Unstable operation or

The pump cannot start

1. Unbalanced impeller

2. Bearing damage

3. Lack of phase

4. Impeller stuck

1. Send to the manufacturer for replacement or calibration

2. Replace

3. Check and repair the circuit

4. Remove debris

excessive current

1. Low working voltage

2. Blocked pipeline impeller

3. Use a low head

4. The height or viscosity of the liquid being pumped is relatively high

1. Adjust the working voltage

2. Clean up blockages in pipelines and impellers

3. Reduce traffic Increase head

4. Change density or viscosity

The pump has noise or

Vibration

1. The pump shaft and motor shaft are not concentric

2. There is gas in the medium

3. Corrosion causes the pump shaft to be unbalanced

4. Loose bolt at the transmission device

5. Bending of pump shaft

1. Adjustment

2. Cooling or pressure reduction

3. Replace

4. Tighten

5. Rectify or change
