Description
- The water saving effect is obvious. Due to the water circulation operation, the water added to the water tank can be recycled and reused, overcoming the phenomenon that a large amount of water is wasted when the vacuum is directly obtained by the method of directly discharging the tap water. This circulating water vacuum pump can be used for a long time with water addition, which is especially suitable in laboratories where water is scarce and water pressure is insufficient. Multi-functional comprehensive use. In addition to providing vacuum conditions, this unit can also provide circulating cooling water. The pump is connected to the tap water source, and the circulating water temperature can be kept constant under the condition of continuous operation for a long time, thereby ensuring that the vacuum degree is not lowered and the supply of circulating cooling water is realized. Novel style, easy to use. The pump head of the machine is directly immersed in water, no kettle is provided, the whole machine has low height, small volume, light weight and convenient movement, and can be placed on the workbench for easy operation and observation. The top cover of the water tank is a live installation and can be opened for easy watering and overhaul. This machine is equipped with five suction nozzles, which can be pumped separately or simultaneously. Each suction nozzle is equipped with a pumping table, which can easily observe the vacuum degree. A check valve is installed on the suction passage to prevent circulating water from flowing back into the vacuumed equipment when the vacuum operation is stopped. Corrosion resistance, no pollution. The pump parts of the machine are made of stainless steel, and the water tank is made of ABS plastic. It is molded once, and is not affected by corrosive substances such as acid and alkali, and there is no pollution laboratory such as oil.
Functions and use: This water circulating vacuum pump is a new multi-purpose vacuum pump designed with circulating water as the working fluid and using the jet to generate the negative pressure principle. It provides vacuum conditions for the chemical laboratory and can provide circulating cooling water to the reaction device. The pump is widely used in evaporation, distillation, crystallization, filtration, sublimation and other operations. It is an ideal equipment for laboratories in universities, pharmaceuticals, food processing and other fields. Specifications: Vacuum degree: -0.098Mpa (circulating water temperature 0~25 degrees Celsius) Pump displacement: 80L/min Single mouth pumping rate: 10L/min Motor power: 370W Working voltage: ~220V±10%50HZ Water tank capacity: 50L Noise: <45DB Head: 12M Self weight: 37kg
