气体增压气压作用介绍

发布时间:2019-01-09 14:43:13   发布人:http://www.sdjingtuo.com
气动气体增压泵靠压缩空气做为动,增压压缩空气及其它气体,如氮气、氩气、氦气、氖气、氧气、氢气等气体的增压。
Pneumatic gas booster pump is driven by compressed air. It boosts compressed air and other gases, such as nitrogen, argon, helium, neon, oxygen and hydrogen.
驱动空气压力一般要为3-8bar(0.3-0.8MPa), 当然不是这个压力范围内,同一台增压泵的增压效果共同的,同一台增压泵的增压比(驱动活,塞与增压活,塞的面积比)是固定的,驱动气压3bar时与驱动气 压8bar时的较大输出压力是不共同。因而不要误解为驱动气压要求为3-8bar,就是指这个压力区间内都能达到同一个压力,因而选型时要根据现场的压缩 空气的压力挑选合适的增压比,一般压力要留有一定的余量。当压力越挨近泵的较大输出压力时,泵的频率越慢,流量越小。
The driving air pressure is usually 3-8bar (0.3-0.8MPa), but it is not within this pressure range. The boosting effect of the same booster pump is the same. The boosting ratio (driving activity, plug-to-booster activity, plug area ratio) of the same booster pump is fixed. The maximum output pressure at driving pressure of 3bar is not the same as that at driving pressure of 8bar. Therefore, do not misunderstand that the driving pressure requirement is 3-8 bar, which means that the same pressure can be achieved in this pressure range. Therefore, when selecting the type, the appropriate boost ratio should be selected according to the pressure of the compressed air on the spot, and the general pressure should leave a certain margin. When the pressure is closer to the maximum output pressure of the pump, the slower the pump frequency is, the smaller the flow rate is.
气体增压泵
原理是大活,塞推进小活,塞往复运动实现增压,跟着压力的出口端压力的上升,大活,塞和小活,塞的两头的力趋于平衡,故增压泵运动频率下降、流 量变小,当出口端的压力是增压泵的增压比时,两头力值平衡,增压泵这时停止作业,流量为0,一旦一端气压下降,增压泵会自动作业,补齐压力,具有自动保 压、补压功能。
The principle is big work, plug pushing small work, plug reciprocating movement to achieve pressurization, with the pressure at the outlet of the pressure rising, big work, plug and small work, the force at both ends of the plug tends to balance, so the movement frequency of the booster pump decreases and the flow rate decreases. When the pressure at the outlet is the boost ratio of the booster pump, the force at both ends is balanced, and the booster pump stops operation at this time, the flow rate is 0, once the pressure at one end is reduced. Down, the booster pump will automatically operate, fill the pressure, with automatic pressure-keeping, pressure-filling function.
耗气量的要求,一般要求流量1m3/min左右,耗气量不是一个固定值,当泵的负载越小时,泵的频率越快,负载越大时,泵的频率越慢,当达到泵 的较大输出压力时,泵停止作业,不在耗气。不建议选用220V电源的空气压缩机,220V的空压机排气量一般都较小,增压泵不能发挥出正常效能。
The requirement of gas consumption is generally about 1 m3/min. The gas consumption is not a fixed value. The smaller the load of the pump, the faster the frequency of the pump and the larger the load, the slower the frequency of the pump. When the maximum output pressure of the pump is reached, the pump stops working and does not consume gas. It is not recommended to choose 220V air compressor. The exhaust volume of 220V air compressor is generally small, and the booster pump can not give full play to its normal efficiency.
