Types of Vacuum Pump
With the development of vacuum applications, there are various kinds of vacuum pumps. Based on their working principles, there are two main types of vacuum pumps, which are gas capture pumps and gas transfer pumps. The commonly used vacuum pumps include water circulating vacuum pump, rotary vane vacuum pump, diffusion pump, reciprocating pump, slide valve pump and roots pump, which are main pumps indispensable in the process of applying vacuum technology in various industries.
Today, let’s further learn something about the water circulating vacuum pump.
What is a Water Circulating Vacuum Pump?
The water circulating vacuum pump, also known as water ring vacuum pump, is a device to remove air or gas molecular from a sealed container by taking water as its working medium. It can not only provide vacuum condition for chemical labs, but offer circulating cooling water for reaction devices. Sometimes it can even serve as a compressor.
What is a Water Circulating Vacuum Pump Used for?
Initially, a water circulating vacuum pump is used as a water suction pump. But gradually it is applied in a great variety of industries, such as petroleum, chemical engineering, mechanical engineering, mining industry, light industry, medicine and food.
As a multi-purpose vacuum pump, a water circulating vacuum pump is extensively used to provide vacuum condition for evaporation, distillation, crystallization, filtration, pressure reduction, sublimation and other operations.
What are Advantages of a Water Circulating Vacuum Pump?
- Multi functions. A water circulating vacuum pump can not only provide a vacuum condition but can do external circulation to provide recirculated cooling water for reaction devices. Directly connected to the tap water, it maintains constant vacuum, water temperature and water quality under the condition of continuous operation by supplying water appropriately. It can lower the vacuum degree as well as provide recirculated cooling water.
- Effectively save water. The water added into the water tank can be recycled for use by adopting the water circulating operation, which avoid the water waste phenomenon. It is especially suitable for laboratories that are lack of water or water pressure.
- High-quality material. The machine body adopts double taps and can be used separately or in parallel with two vacuum gauges. The main engine is made of the stainless steel movement and anti-corrosion movement. It is corrosion resistant, non-polluting, low noise and easy to move. The vacuum valve can be installed according to users’ need. Four students are allowed to do chemical experiments at the same time so that the experimental space can be reduced.
