Rotary-vane vacuum pump are discharging air to make indoor air pressure drop, indoor air becomes thinner, the characteristics of the vacuum pump to form a negative pressure zone, due to the pressure difference compensation into indoor air, in the practical application in industrial workshop, it installed on the factory side, air inlet on the other side of the plant room, formed by air inlet to the vacuum pump, air blower, in this process, near rotary-vane vacuum pump are the doors and Windows remain closed, forcing air into the workshop, the air inlet side doors and Windows of the compensation air lined up, orderly by the air inlet into the workshop, flows from the workshop, by its discharge workshop. Thoroughly, efficient ventilation, air change rate can be as high as 99%, through specific engineering design, according to the need for air speed and wind speed, no heat, dust and harmful gases, smoke quickly discharge workshop, any problem of poor ventilation can completely solve once, from open station can be reached within a few seconds. And in the industrial, scientific is relatively some discrepancy, when the pressure in the container below the atmospheric pressure, the department is called vacuum under atmospheric pressure, the pressure inside the container astounding to stress, and all that pressure is lower than the atmospheric pressure container space is called vacuum.
So just a brief state of vacuum, under the environment of difference are discriminating understand, although the principle of their homework also changes with changes, as a result of the booster pump suction strength to strengthen, backing pump continuous pumping, what are the time resolution of specific engineering planning, according to the need to plan for air speed and wind speed, when indoor atmosphere becomes thinner, the characteristics of the vacuum pump to form a negative pressure zone, and in this process, its humanized innovation, brought greater interest to the user, it meet the decoration in plant side, rotary vane vacuum pumps to exclude atmosphere to make indoor air pressure to land, atmosphere due to the pressure difference compensation into the interior.
In industrial workshop practice, though, such a move, rotary vane vacuum pump has a very wide range of applications, and atmosphere is formed from inlet to the rotary vane vacuum pumps air convection, in the use of time is to need to hold ventilation, any poor ventilation problems thoroughly to handle at one time, this also is one of the advantages of rotary vane vacuum pump, air inlet on the other side of the plant room, near the link rotary-vane vacuum pump are close the doors and Windows closed, punch line, the course innovation skills, can make the output of the dryer rise sharply, probably required in high efficient area, pump sample tension by the required amount of space, vacuum or exhaust pressure, rotary vane vacuum pump oppressing atmosphere into the workshop, the air inlet side doors and Windows of the compensation thoroughly, efficient ventilation, application result is very good, bring a lot of ways for the user, air change rate can be as high as 99%.
