Gear screw pump is a common fluid transfer equipment that is widely used in various industrial fields. It combines the principle of gears and screws, using the gap between the meshing gears and screws to draw fluid in and deliver it to its destination. This article will introduce in detail the working principle, characteristics, application and selection of gear screw pumps.
First, the working principle.
The gear screw pump is mainly composed of a pair of meshing gears and screws, in which the screw is the driving part and the gear is the driven part. When the screw rotates, its spiral groove drives the gear meshing to rotate, resulting in a series of continuous sealing chambers. As the screw rotates, the fluid in the sealing chamber is continuously sucked in and discharged, and the fluid is transported.
2. Features. 1.Stable flow rate: The flow output of the gear screw pump is relatively stable and is not affected by fluid viscosity, temperature and other factors.
2.High pressure: Due to the close fit of the gear and screw, the gear progressive cavity pump is able to withstand high pressures and is suitable for transporting fluids over long distances.
3.High reliability: The gear screw pump has simple structure, few parts, easy maintenance and high reliability.
4.Wide range of applications: Gear screw pumps are suitable for conveying various fluids, such as lubricating oil, hydraulic oil, fuel oil, etc.
5.Low noise: The gear progressive cavity pump is designed with a focus on noise reduction and low noise during operation.
3. Application. Gear screw pumps are widely used in various industrial fields, such as petroleum, chemical industry, electric power, shipbuilding, metallurgy, etc. In the petroleum industry, gear screw pumps are used to convey **, lubricating oil, etc.; In the chemical industry, gear screw pumps are used to transport corrosive fluids such as acids, alkalis, and salts; In the power industry, gear screw pumps are used to transport fuels, lubricating oils, etc.; In the marine and metallurgical industries, gear screw pumps are also widely used.
Fourth, the selection. When choosing a gear screw pump, it is necessary to select according to the actual needs. Factors to consider include flow, pressure, viscosity, temperature, corrosiveness, and installation and maintenance requirements. At the same time, factors such as pump efficiency and energy consumption need to be considered. When choosing, you should choose a brand and model of reliable quality to ensure long-term stable use results.
5. Maintenance and maintenance.
In order to ensure the long life and efficient operation of the gear progressive cavity pump, regular maintenance and maintenance are required. Specifically, it includes the following aspects:
1.Regularly check the operation status of the pump, and deal with it in time if any abnormalities are found;
2.Regularly clean the inside of the pump and related pipes to keep it clean;
3.Replace wearing parts such as lubricating oil and seals regularly;
4.Carry out regular overhaul and maintenance of the pump, such as cleaning the bearings, checking the wear of gears and screws, etc.;
5.Do a good job of equipment maintenance records to facilitate subsequent management and maintenance.
In a word, as a common fluid transfer equipment, gear screw pump has a wide range of application prospects. Understanding its working principle, characteristics, application and selection will help to better select and use gear screw pumps, improve production efficiency and management level. At the same time, doing a good job in the maintenance of equipment is also an important measure to ensure its long-term stable operation.
