4. Working conditions:
The temperature of the medium being transported shall not exceed 80 degrees Celsius.
The weight of the transported medium is 1-1.3Kg/dm3.
The material of this pump is mainly cast iron and cannot be used to transport highly corrosive liquids.
When the water pump is working, the surrounding area of the pump should be well ventilated.
1Cr18Ni9Ti stainless steel material can be used to transport various corrosive liquids.
The pipeline sewage pump has no self suction capacity, and liquid must flow into the pump body. The pump can only play a boosting role. If the liquid level is lower than the pump, please choose a self suction sewage pump product to be suitable.
If users have special requirements, please indicate the relevant information of the conveying medium when placing an order. Shanghai Jiushi Pump Industry provides more reliable products.
5. Working Principle：
Main Components:
1. Pump body: The main structure of the pump, which accommodates liquid and forms a pumping channel.
Impeller: Connected to the motor shaft, it generates centrifugal force through rotation, driving the flow of liquid.
Motor: Provides power source for impeller rotation.
Shaft seal: prevents liquid from leaking between the pump body and the motor.
Inlet and outlet pipelines: Connect the inlet and outlet of the pump to form a flow path for the liquid.
Work Steps:
Start the motor: When the pump starts, the motor drives the impeller to rotate.
Liquid suction: When the impeller rotates, the liquid between the blades is thrown towards the periphery of the pump body due to centrifugal force, forming a low-pressure area that attracts external liquid to enter the pump body through the inlet pipeline.
Liquid acceleration: As the impeller continues to rotate, the liquid gains acceleration between the blades, kinetic energy, and pressure increase.
Liquid discharge: The accelerated liquid enters the outlet pipeline of the pump body through the outer edge of the impeller, forming a continuous flow path inside the pump body, and finally discharged through the outlet pipeline.
Continuous circulation: With the continuous rotation of the impeller, the liquid is continuously sucked in, accelerated, and discharged, forming a continuous cycle.
6. Structural Diagram:
1. Durable and wear-resistant. The 100GW100-30-15 sewage pump can not only operate safely for more than 8000 hours continuously, but its double end face series mechanical seal made of hard and corrosion-resistant tungsten carbide material also makes it more durable.
2. The ability of sewage to pass through has significantly improved. The special design of the anti clogging hydraulic components in the large flow channel not only effectively passes through solid particles with a diameter of about 50% of the pump diameter, but also smoothly discharges fiber substances 5 times the pump diameter.
3. The energy-saving effect has been greatly improved. The innovative and reasonable design, as well as the appropriate matching motor, greatly improves its efficiency.
4. To ensure its safe and reliable operation, users can be equipped with a fully automatic safety protection control cabinet to monitor the pump's overheating, leakage, overload, and leakage in real-time. And ensure that the motor of the product does not experience overload operation within the range of usage head.
7. Precautions for use:
Pre installation inspection: Ensure that there are no debris inside the pump and pipeline, and that the connections are well sealed.
Regular maintenance: Regularly inspect and replace vulnerable parts to maintain the pump in good operating condition.
Prevent dry operation: Ensure that there is enough liquid entering the pump body before starting the pump to avoid damage during idle operation.
Pay attention to motor protection: Install appropriate motor protection devices to prevent motor overload operation.
The GW series pipeline sewage pump, with its high efficiency, reliability, and durability, is widely used in various sewage treatment facilities and has become one of the important equipment in sewage discharge systems.
Through the above working principles and precautions, it is possible to effectively understand and use the GW series pipeline sewage pump, ensuring its efficient operation in sewage treatment.
8. Installation and use
Check whether the external fasteners are loose during transportation.
Check if the power supply voltage meets the requirements of the motor nameplate.
Connect the power and test run to see if the impeller rotates in the direction indicated on the pump. If the direction is reversed, simply swap any two phase wires in the cable. The test run should not be too long to avoid burning the seal.
Install and start the pump. Can you please install the pump foot screws.
9. Inspection and maintenance
1. Before using the pump, the insulation resistance of the motor winding to the casing should be checked. If it is less than 0.5 megaohms, the stator must be dried and can only be used after the insulation resistance increases.
If the gap between the impeller and the oil seal at the inlet of the pump body exceeds 2mm, the wear-resistant oil seal should be replaced.
When there is water leakage in the pump seal, the seal should be replaced in a timely manner. When replacing, first install the static seal flat and then seal the dynamic seal on the shaft.
When replacing the impeller, use a puller to pull it out, and do not use a hammer to forcefully hit it to avoid damaging the shaft alignment.
10. Common fault causes
No water is discharged, and the weight and particle size of the pumped liquid are too high; Blocked liquid flow channel; Wrong impeller rotation; The bar material is pulled into the impeller and gets stuck; The outlet height of the pipeline exceeds the rated head height.
Insufficient flow and low head. Low voltage, incorrect impeller rotation, or wear of wear-resistant seals; The liquid has a heavy particle size that is too high.
The insulation resistance is low, the surrounding environment is humid, and the mechanical seal is severely leaking.
