IMO screw pump Basic principle and structure of
IMO Screw pump It is a positive displacement pump for conveying various liquids. It is composed of a pair of coaxial rotating screws and a pump body. The shape of the screw is a double helix, and there is a certain gap between their gears. When the screw rotates, the liquid is sucked into the pump body, then compressed and pushed out of the pump body.
The main structure of IMO screw pump includes pump body, screw, shaft and bearing. The pump body is usually made of cast iron or steel, with high strength and corrosion resistance. The screw is made of high-strength alloy steel, with good wear resistance and corrosion resistance. Shaft is an important part connecting screw and motor, usually made of stainless steel. The bearing is used to support the shaft and screw, so that they can rotate smoothly.
The advantages of IMO screw pump include high efficiency, low noise, low vibration, good stability, easy maintenance, etc. They are widely used in petroleum, chemical, pharmaceutical, food, paper making, sewage treatment and other fields.
Article 2: Classification and application of IMO screw pump
IMO screw pumps can be divided into single screw pumps and twin screw pumps according to their different structures and uses. Single screw pump is usually used to transport liquids with high viscosity, such as petroleum, asphalt, syrup, glue, etc. Twin screw pump is usually used to transport liquid with lower viscosity, such as water, solution, fuel, etc.
IMO screw pumps are widely used in petroleum, chemical, pharmaceutical, food, paper making, sewage treatment and other fields. In the petroleum industry, they are used to transport crude oil, natural gas, asphalt, petroleum ether, naphtha, etc. In the chemical industry, they are used to transport various chemicals, plastics, rubber, etc. In the pharmaceutical industry, they are used to transport various drugs and reagents. In the food industry, they are used to transport various food raw materials and finished products. In the paper industry, they are used to transport all kinds of pulp. In sewage treatment, they are used to transport various sewage and sludge.
Maintenance of IMO screw pump
The maintenance of IMO screw pump is very important for its long-term stable operation. The following are some maintenance suggestions for IMO screw pump:
1. Regularly check the wear of pump body, screw, shaft and bearing, and timely replace the worn parts.
2. Regularly check the bearing lubrication to ensure that the lubricating oil is sufficient and clean.
3. Regularly clean the scale and sediment inside the pump body and on the screw surface.
4. Regularly check the cable, motor bearing and motor insulation of the motor to ensure the normal operation of the motor.
5. Regularly check the connection between pump body and pipeline to ensure no water leakage.
6. Regularly check the vibration of the pump body and pipeline to ensure the stable operation of the pump.
Troubleshooting of IMO screw pump
IMO screw pump may encounter some faults during use. The following are some common faults and troubleshooting methods:
1. Water leakage of pump body: it may be that the seal of pump body is not tight or the pipe connection is loose, and it is necessary to retighten the seal or pipe connection.
2. Pump body vibration: it may be that the support between the pump body and the pipeline is unstable or the screw is damaged, and it is necessary to readjust the support between the pump body and the pipeline or replace the screw.
3. Excessive noise of the pump body: it may be that the bearing is damaged or the screw is worn, and the bearing or screw needs to be replaced.
4. Insufficient flow of the pump body: it may be that the inlet valve of the pump body is closed or the scale inside the pump body needs to be opened or the inside of the pump body needs to be cleaned.
5. The temperature of the pump body is too high: it may be that the lubricating oil inside the pump body is insufficient or the scale inside the pump body needs to be added or cleaned.
