Rotary Vacuum Pump Textile Industry

Rotary vane vacuum pump application and scope


1. Vacuum pump is the basic equipment used to extract gases from a specific sealer to obtain a certain degree of vacuum for the container. Due to the high development of modern science and technology, the application of vacuum pump is widely used in various scientific fields and various enterprises and institutions. It can be used in metallurgy, chemical industry, light industry, petroleum, medical treatment, pharmacy, printing and dyeing, electrical appliances, vacuum, semiconductor, food, atomic energy and spinning. Weaving and other scientific research institutions, colleges and universities, industrial and mining enterprises for scientific research, production and teaching purposes.


2. Because the vacuum pump is made of ferrous metal and is relatively precise, the work of the whole pump is connected with oil, so it is not suitable for pumping out all kinds of gases which contain too much oxygen, poisonous, explosive, corrode ferrous metal and have chemical effect on vacuum oil, nor can it be used as compressor and conveying pump. If there is a pump with an air-ballast device, a certain amount of condensable vapor can be removed.


3. Vacuum pumps can be used to directly obtain vacuum below 10-3 torres, and to cooperate with other vacuum equipment to obtain vacuum above 10-3 torres.


4. Vacuum pumps are generally used at room temperature not less than 5 degrees Celsius and at relative temperature not higher than 90%.


5. Vacuum refers to the residual gas pressure in the pumped container. The partial pressure is divided into the factory standard and the total pressure is the auxiliary standard. The thermocouple measures the total pressure of various vapors and permanent gases, while Maxwell can only measure the partial pressure of permanent gases, so the values in the table are different.


6. Pumping speed is the atmospheric pressure calculated according to the geometric size. The actual pumping speed is basically consistent with the geometric pumping speed. At various pressures, the pumping speed decreases to a certain extent. The relationship between pumping speed and pressure is shown in the following figure.


7. Temperature rise refers to the difference between the greenhouse and the greenhouse of oil at the exhaust valve after the pump temperature is stable.


8. Model representation: Example 2X-15, 2 for double-stage pump, X for rotary vane vacuum pump, 15 behind yellow line for pumping speed per second.

Rotary vane vacuum pump is the basic equipment used to extract gases from a specific sealed container, so that the container can obtain a certain vacuum. Due to the high development of modern science and technology, the application of vacuum pump is widely used in various scientific fields and various enterprises and institutions. It can be used in metallurgy, chemical industry, light industry, petroleum, medical treatment, pharmacy, printing and dyeing, electrical appliances, vacuum, semiconductor, food, atomic energy, etc. Textile and other scientific research institutions, colleges and universities, industrial and mining enterprises for scientific research and production and teaching; and widely used in oil press.


Because the rotary vane vacuum pump is made of ferrous metal and is more precise, the whole pump work is linked together, so it is not suitable for pumping out all kinds of gases which contain too much oxygen, poisonous, explosive erosion of ferrous metal and chemical effect on vacuum oil, nor can it be used as compressor and conveying pump. If there is a pump with an air-ballast device, a certain amount of condensable vapor can be removed.


The vacuum unit is made up of Roots vacuum pump as the main pump and liquid ring vacuum pump as the front pump in series. The Roots water ring pump unit uses water ring vacuum pump as the front pump, which is more advantageous than other vacuum pumps. It overcomes the limitation pressure difference of single liquid ring pump and the shortcoming of low pumping rate under a certain pressure. At the same time, it retains the Roots vacuum pump can work quickly and has larger pumping capacity. Advantages of gas rate.
