The development history of water pumps is extremely long. My country had “water pumps” as early as 1600 BC in the Shang Dynasty. At that time, it was also called jié gáo. It was a tool used to transport water for agricultural irrigation. With recent With the development of modern industry, the uses of water pumps are constantly being expanded, and are not limited to water use. Let’s take a look at where water pumps are used in various industries.

01 Agriculture
As the primary industry, agriculture is the foundation for the development of the national economy and the survival of the people. Agriculture is as dependent on water pumps as plants are on water. In terms of farmland irrigation, the South is dominated by individual farmers. When planting rice and other crops, farmers mostly draw water from small rivers. The irrigation volume is large and takes a long time. This type of agricultural irrigation is suitable for small self-priming pumps, while irrigation in the North mostly draws water from small rivers. River water and well water are suitable for submersible pumps when the lines are long and the height difference is large.

In addition to farmland irrigation, drinking water for livestock and poultry is also inseparable from water pumps. Needless to say, large farms can use non-negative pressure water supply systems to connect tap water pipes to achieve constant pressure water supply to ensure that water is available at any time; pastoral areas such as Inner Mongolia Groundwater needs to be extracted and stored in water storage tanks to meet domestic and livestock water needs, and submersible pumps and self-priming pumps are indispensable.

02 Shipping industry
The number of water pumps on large ships is generally 100 or more, and they are mainly used in four aspects: 1. Drainage system, to discharge the accumulated water at the bottom of the ship to avoid ensuring the safety of the hull. 2. Cooling system, the water pump transports water to the cooling equipment to ensure the normal operation of engines and diesel engines and other equipment, and maintain the stability of the power system. 3. Fire protection system. The water pump in the fire protection system needs to have self-priming and pressurization functions, so that it can quickly respond to the fire and extinguish the fire in a timely manner. 4. Wastewater treatment system: The treated wastewater must be discharged through a water pump at a certain amount and speed during the voyage to reduce damage and pollution to the marine environment.

In addition to the above specific uses, the water pump can also be used to clean the deck, flush the cargo hold, and can also adjust the displacement of the ship by increasing water and discharging water when loading and unloading cargo to control the balance of the hull and the speed of travel.
03 Chemical industry
Pumps in the chemical industry mainly have three major functions: transportation, cooling, and explosion protection. Transportation mainly includes transporting raw material liquids from storage tanks to reaction vessels or mixing vessels to participate in the production of the next process. In the cooling system, the pump is used in the circulation of cooling water, heating cycle, etc., to cool down the production equipment in time to ensure continuous operation. In addition, the chemical industry has a certain degree of danger, and it is necessary to choose explosion-proof when transporting toxic and harmful liquids and flammable liquids. Water pump, so the water pump also plays a role in ensuring safety.

04 Energy Metallurgy
Water pumps are also widely used in the energy metallurgical industry. For example, in the mining of mines, the accumulated water in the mine usually needs to be removed first, while in metal smelting operations, water needs to be supplied first to prepare for cooling. Another example is that the cooling towers of nuclear power plants also require water pumps to supply water, which can be divided into three parts: water spraying, contact between water and air, and water discharge. Moreover, the sewage from nuclear power plants is radioactive, and leakage during transportation will harm the environment. Cause irreparable damage, which places extremely high requirements on the material selection and sealing level of the water pump.

Water pumps are the most widely used machinery. They are inseparable from life and production. In addition to the above-mentioned industries, water pumps also play an indispensable role in the aerospace and military fields.
