The pump is a machine that transports liquid or makes liquid supercharged.It transmits the mechanical energy or other external energy of the original motivation to the liquid to increase liquid energy. It is mainly used to transport liquids including water, oil, pH, emulsifier, suspension and liquid metal.
What are the uses of water pumps
Practical application
It is widely used in shipbuilding, oil mining, and loading machines.In 2008, the ship output reached 15,000 tons, and the amount of loaded tonal accounted for 21%of the worlds market. By 2015, it would become the worlds largest shipbuilding country.In order to ensure the normal navigation or tie of the ship and meet the needs of the crew and passengers, each ship must be equipped with a certain number of ship pumps that can play a corresponding role. The ship pump is one of the important auxiliary machines.According to incomplete statistics, among various ships auxiliary machinery and equipment, the total number of types of ship pumps of various types and different uses accounts for about 20%-30%of the total number of ship machinery and equipment.The proportion is also relatively large.In the total cost, the ship pump accounts for about 4%-8%of the cost of the ships equipment. Generally, the shipping pump for a medium-sized ship can purchase more than 10 million yuan.When it comes to the pump market, it is necessary to say that the Western Qi East Inspection Project that has been completed in my country is also required for pump products in the Western Gas East Transmission Project.At the same time, the state also needs to build other natural gas pipelines, and a large number of pump products are also needed in these projects.
Different use
The water pump has different uses, different transport liquid media, different flows, and the range of different ranges. Therefore, of course, its structure forms are different, and the materials are different. Summary, it can be roughly divided into:
1. Urban water supply 2. Sewage system 3. Civil engineering, construction system 4. Agricultural water conservancy system 5. Power station system
6. Chemical system 7. Petroleum industry system 8. Mining metallurgy system 9. Light Industry System 10. Shipping System
What to pay attention to in the pump
1. If there are any small faults in the pump, remember not to let it work.If the pump axis is worn in time after the fillers are worn, it will leak air if the pump is continued.The direct impact of this is that the energy consumption of the motor will increase the impeller.
2. If the water pump occurs strongly during the use of the use of a strong vibration, it must be stopped to check what the reason is, otherwise it will also cause damage to the pump.
3. When the water pump bottom valve leaks water, some people will fill them into the pump inlet pipe with dry soil and rush to the bottom valve with water. This method is really not desirable.Because when the dry soil is put in the water pipe, when the pump starts to work, these dry soil will enter the pump. At this time, it will damage the water pump impeller and bearings, which shortens the life of the pump.When the bottom valve leaks, it must be used for repair. If it is serious, you need to replace the new one.
4. Pay attention to maintenance after the pump is used. For example, when the pump is used, the water in the pump should be cleaned. It is best to remove the water pipe and then rinse with water.
5. The tape on the pump must also be removed, then rinse with water and dry it in the light. Do not put the tape in a dark and humid place.The tape of the pump must not be stained with oil, let alone apply something sticky on the tape.
6. Carefully check whether there are cracks on the impeller, and whether the leaf wheels are fixed on the bearings. If there is a crack and loosening, it should be repaired in time.
