Water pumps are now very popular in our country such as: Masflo pumps - France, Hyosung Pumps - Korea ... And for each of us, no one is strangers to water pumps anymore, but in history. pump, not everyone knows. In today's article, Dai Nam would like to share with you some interesting things!
Due to living conditions, people need water and have to use rudimentary tools such as: a spinning wheel, a water bike, a bucket, a bucket ... to bring water to crops, trees, to bring water to the house. for domestic use ... These tools are mainly for the purpose of transporting fluids from source to places where water is needed. Later it was known to use simple plungers such as enemas made of wooden bamboo to transfer water under excess pressure. The rudimentary water pumps operate under the influence of manpower and animal traction, so the pumping capacity is not high, the efficiency is low ... And then the rudimentary water pump operates under the impact of power. human and animal traction. Therefore, the pumping capacity is not high, the efficiency is low and it is extremely strenuous and laborious.

And then after many innovative ideas, in the first and second centuries BC, the Greeks invented the wooden plunger. By the 15th century, the Italian scientist D. Franxi introduced the concept of centrifugal pumps. In the 16th century, a new type of rotor pump appeared. And until the 17th century, a French physicist applying the studies of Professor D. Francium produced the first centrifugal water pump. However, because there are no motors with large revolutions to pull the pump, so the pumping capacity is small, so the centrifugal pump has not been developed yet, at that time the rotor pump was dominant in all types of pumps.
Later in the 18th century, the Russian scholar Euler proposed theoretical problems related to hydraulic machines and Zucôpsky proposed theories of fluid mechanics, ever since. The new pump has a solid base. At this time a steam engine was introduced, increasing the ability to pull the pump. In the early 20th century, when motors with rapid revolutions were introduced, centrifugal pumps were more widely available and highly efficient, with greater pumping capacity (the latter was at the forefront of manufacturing in this fashion. are pumps).
Nowadays, water pumps are widely used in the life and national economic sectors.
- In industry, water pumps are used to supply water to blast furnaces, mines, factories, oil pumps, ...
- In the oil exploitation industry
- In the aircraft manufacturing industry
- Pumps are used in nuclear power plants.
- In agriculture, pumps are used to pump water for irrigation and for waterlogging. In life, the pump is used to supply clean water for human and livestock needs.
In our country, since the French colonial period, a number of small irrigation pump stations have been built, the largest one is the pump station in Son La with a capacity of 38,000 m3 / h, the flow of each pump Q = 3 m3 / s.
