1. In the mining and metallurgical industry, the pump is also the most used equipment. Mines need to be drained by pumps, and in the process of beneficiation, smelting and rolling, pumps are needed to supply water first.
2. In the power sector, nuclear power plants need nuclear main pumps, secondary pumps, tertiary pumps, and thermal power plants need a large number of boiler feed pumps, condensate pumps, circulating water pumps, and ash pumps.
3. In national defense construction, pumps are required for the adjustment of aircraft flaps, tail rudder and landing gear, the rotation of warships and tank turrets, and the sinking and floating of submarines. High pressure and radioactive liquids, and some also require the pump to be free of any leakage.
4. In agricultural production, the pump is the main drainage and irrigation machinery. China's rural areas are vast, and a large number of pumps are needed in rural areas every year, and generally speaking, agricultural pumps account for more than half of the total pump output.
5. In the production of chemical and petroleum sectors, raw materials, semi-finished products and finished products are mostly liquids, and the raw materials are made into semi-finished products and finished products, which need to go through complex processes, and pumps play a role in transporting liquids and providing pressure flow for chemical reactions in these processes, in addition, pumps are also used to regulate the temperature in many devices.
6. In the shipbuilding industry, there are generally more than 100 pumps used on each ocean-going vessel, and their types are also varied. Others, such as water supply and drainage in cities, water for steam locomotives, lubrication and cooling in machine tools, bleaching and dyes in the textile industry, pulp in the paper industry, and milk and sugar in the food industry, all require a large number of pumps.

How do Rexroth piston pumps supply oil?
1. Straight shaft swash plate Rexroth piston pump is divided into two types: pressure oil supply type and self-priming oil supply type. Most of the pressure oil supply hydraulic pumps use oil tanks with air pressure, and there are also hydraulic pumps with oil replenishment sub-pumps to provide pressure oil to the oil inlet of the hydraulic pump. The self-priming hydraulic pump has a strong self-priming capacity ...
