Rotary vane vacuum pump used in nitrogen replacement device _

before using nitrogen replacement device is not fully conform to the requirements of the standard of drug production and management of the GMP standard, also can't meet the requirements of pharmaceutical manufacturers to the equipment itself. Therefore, it is necessary to develop a simple structure, simple technology, convenient installation, improve the finished product production, reduce the cross contamination, increase the rate of drying equipment, improve the productivity of the nitrogen replacement device. Rotary vane vacuum water pump in the application of nitrogen replacement device should be able to alleviate the situation. As for why I recommended rotary vane vacuum pumps, as long as you complete reading this article, you will understand.

nitrogen replacement device is the replacing device, the combustible gas through the pipeline or container before use. Flammable gas through the pipeline or container should be flush with nitrogen before use. The purpose is to discharge the air in the pipeline, to avoid the flammable gas and combustible mixture of oxygen in the air, which may lead to internal combustion or explosion. Nitrogen replacement equipment including: nitrogen receive accessories, liquefied petroleum gas, nitrogen gas bottle and liquefied petroleum gas tanker. At the same time, the nitrogen bottles and liquefied petroleum gas tank car can temporarily gathered at the scene.

more nitrogen replacement device are analyzed, and then into the topic of this article.

rotary vane vacuum pumps are two levels of structures. Its performance is composed of two parts: high pressure stage and low pressure stage. The inlet connected to the vacuum container or a vacuum device, and the gases in the container during operation by a large number of suction and discharge. When the device is vacuum, high pressure exhaust valve will be closed, high pressure stage extraction gas will be transferred to the second level, and through the secondary suction and discharge, so vacuum equipment can obtain a certain vacuum. The technical parameters of the water pump 6 x 10 - 2pa。 According to the usage of the user, it can be equipped with vacuum booster pump ( Such as the roots pump) , rotary vane vacuum pumps as backing pump. The increased as a result of the booster pump pumping force, before the pump can water pump out in a row, this can make you more equipment. High vacuum pump.

1 operation. First of all, the new tanker tankers and grounding accident and to eliminate static electricity. Then, connect nitrogen displacement device.

in particular, nitrogen bottles of exports by 25 mm diameter nitrogen pipe connected to the tank car accident gas phase, KongGuanChe liquid pipe and tank car accident of liquid through a diameter of 50 mm of liquefied petroleum gas pipeline.

2 start operation. Open the relevant valves, such as nitrogen gas bottle, for replacement. Because of the pressure gauge, check valve and gate installed in the nitrogen bottles at the exit, so you can easily replace nitrogen cylinder one by one.

nitrogen replacement device for natural gas car modification detection equipment. Nitrogen replacement device used to extract air for nitrogen replacement. Vacuum for - 0. 086 mpa, rotary vane vacuum pump instead of vacuum. The nitrogen pressure of 0. 2mpa。 Nitrogen replacement device including vacuum gauge, nitrogen pressure gauge, pressure tube and the base of four mobile wheels.
