Rotary vane vacuum pump used in the gas cycle _

rotary vane vacuum pump application in gas cycle. Global material cycle can be divided into three types: water, gas cycle and sedimentary cycle. Belong to the type of gas and its molecular or any material must be of certain compounds in gas form to participate in the cycle. In scientific research and laboratory, vacuum pump is usually used in gas cycle, gas sampling, the suction filter, vacuum pump and indirect pumping areas. So which vacuum pump should be used for gas cycle?

then, carried out in accordance with the rotary-vane vacuum pump company details.

first of all, let's take a look at the gas cycle. There are two kinds of gas circulation, circulation is a kind of natural gas, the other is a kind of industrial gas cycle. Today, we mainly introduce industrial gas cycle. Often encountered in chemical and pharmaceutical industry gas Liquid dispersion and reaction problems, such as the nitro aromatic compound, fat nitrile, olefins and liquid phase catalytic hydrogenation of alkynes, alkylation reaction, carbonylation reaction, oxidation reaction, etc. Common feature is the reaction rate suffer indignities/liquid mass transfer control, gas/liquid mass transfer involving gas dispersion, gas circulation and process, such as solid catalyst in suspension problem become complicated.

due to the incompatibility of gas and liquid, and the density difference is very big, not reflected in the gas-liquid reactor gas accumulation in the upper part of the space in the reactor, which seriously affect the reaction rate and efficiency. At the same time, the solid catalyst slurry non-uniformity also limits the rate of reaction. In order to improve the response speed, outside the industry generally USES gas circulation, gas and liquid outer loop circulating three modes.

next, let's take a look at the role of vacuum pump in the gas cycle. Gas circulation pump is used for gas cycle of rotary-vane vacuum water pump, which has an inlet and an exhaust nozzle and an exhaust nozzle, and can be continuous vacuum or negative pressure formed at the entrance; In the exhaust nozzle form micro positive pressure. Working medium is gas, mainly for the gas circulation of small equipment. Gas circulating pump working principle: the circular motion of the motor and pump in the diaphragm reciprocating motion by mechanical eccentric device, thereby air compression and tensile fixed displacement pump cavity, forming a vacuum ( Negative pressure) ) In the pump in producing pressure difference between inlet and the external atmosphere. Under the action of pressure difference, the gas is pressurized, Inhalation) To the pump chamber and discharge from the vent.

1. Due to internal main part is the diaphragm, there is no need to use oil pollution-free transmission can be realized and free maintenance.

2, easy installation, can be installed in any direction, from the spatial direction control.

3, low energy consumption, motor for dc power supply, voltage 24 v within the safe and reliable.

4, widely used in portable instrument gas cycle, mobile and handheld devices of gas cycle, is an ideal portable products accessories.
