The circulating water vacuum pump uses tap water as the working medium. The circulating water vacuum pump has the following four advantages.
1. Multifunctional comprehensive function: In addition to providing vacuum conditions, external circulation operation can also be carried out to provide cooling water for the reaction device. The circulating water is usually connected to the water source by vacuum pump. The temperature and water quality of the circulating water of the vacuum pump can be kept constant under the condition of continuous operation for a long time through appropriate supplementary water source, which not only ensures the reduction of vacuum degree, but also ensures the supply of circulating cooling water.
2. Remarkable water-saving effect: because it is a water circulation operation, the water in the sink can be recycled. Based on the measurement, the product can save more than 10 tons of water when the same vacuum degree is reached. One time water can be used for a long time. It is especially suitable for laboratories lacking water source or insufficient water pressure.
3. Double meters and double air extraction ports: the circulating water multipurpose vacuum pump is equipped with two air extraction nozzles, which can work independently or simultaneously. Each air extraction nozzle is equipped with a vacuum gauge to observe the vacuum degree. A check valve is installed in the air extraction pipeline to prevent accidental shutdown during vacuum extraction and return of circulating water to the equipment.
4. Corrosion resistance and zero pollution: the part of the pump is made of stainless steel, which is not affected by corrosive substances such as acid and alkali, and will not produce oil stains, impurities, etc.
