Product details
1、 Overview of YW type submersible sewage pump products
The YW type submersible sewage pump, also known as the submersible pump, is a new generation of pump products developed based on the introduction of advanced foreign technology and the characteristics of domestic water pump usage. It has significant energy-saving effects, anti winding, non clogging, automatic installation, and automatic control. It has a unique effect in the discharge of solid particles and long fiber waste. This series of pumps adopts a unique impeller structure and a new type of 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.
2、 Product features of YW type submersible sewage pump
1. Adopting a unique 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, and has significant energy-saving effects. It is easy to maintain and does not require the construction of a pump room. It 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 sewage 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 15 meters.
7. The shaft connection structure is advanced and 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.
IIIYW type unobstructed submersible sewage pumpUsage precautions:
1. Should the pump be carefully inspected before use? Is there any damage to the pump and motor Check? Tightening condition of fasteners.2. Check the rotary pump? Is there any friction sound Check together? Concentricity between pump shaft and 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 there are special circumstances, it is necessary to equip the water pump with a fully active 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 for a long time (usually using a head not less than 60% of the additional head) The best way to control it is within the proposed head scale The waterproof pump burned out the motor due to overload.
4YW type submersible sewage pumpApplication instructions:
Start:
1. Start the experiment and check if the motor direction and pump requirements are consistent.
2. Valves and pressure gauges on the closed outlet pipeline.
3. Start the motor and turn on the pressure gauge. Gradually open the outlet pipeline valve to the desired position until it runs normally.
Parking:
1. Gradually close the outlet gate valve, stop the motor, and close the pressure gauge
2. When parking for a long time, the pump should be removed, reassembled, and properly stored.
Disassemble:
1. Close the outlet valve and remove the joint bolts on the flange.
2. Loosen the motor base and connecting end cap bolts, and remove the motor.
3. Loosen the bolts that fix the pump on the foundation, remove the pump, and rinse it with clean water to prevent oxidation.
4. Remove the base, pump body, and outlet pipe, loosen the impeller nut, and remove the impeller.
5. Remove the oil chamber and mechanical seal, remove the extension tube and bearing seat, and take out the extension shaft.
