气体增压泵在购买选型上应该注意什么?

一,根据增压介质肯定增压泵类型。
First, confirm the type of booster pump according to the booster medium.
比如,增压介质是空气/氮气,我们就在空气增压泵/氮气增压器中选.增压介质是气体,我们就在气体增压器中选;增压介质是液体,我们就在气动液体增压泵中选。
For example, if the booster medium is air/nitrogen, we will choose it in the air booster pump/nitrogen booster. If the booster medium is gas, we will choose it in the gas booster; if the booster medium is liquid, we will choose it in the pneumatic liquid booster pump.
第二,根据系统所需压力初步肯定泵的型号。
Secondly, the type of pump is confirmed preliminarily according to the pressure required by the system.
普通地,玖容厂家的气动增压泵的驱动气压≤8bar。所以,增压比Ratio=Po/Pa。其中,Po是系统的输出压力;Pa是气动泵的驱动压力,普通取较大值0.7MPa。根据计算出来的增压比,在相应类型的泵表中选择型号。
Generally speaking, the driving pressure of the pneumatic booster pump of the manufacturer is less than 8 bar. So, the boost ratio is Ratio = Po / Pa. Among them, Po is the output pressure of the system; Pa is the driving pressure of the pneumatic pump, with a maximum value of 0.7 MPa. According to the calculated boost ratio, the type of pump is selected in the corresponding type of pump meter.
气体增压泵
留意,通常我们会选择增压比略高于计算值的泵,以确保我们的泵在通常情况下都能输出系统所需压力。
Note that we usually choose pumps with a boost ratio slightly higher than the calculated value to ensure that our pumps can normally output the pressure required by the system.
第三,核算泵的流量能否满足系统恳求。
Third, whether the flow of the pump can meet the system's request.
当我们根据泵的出口压力初步选择了泵的型号后,我们需求核算改泵的流量能否满足恳求。泵的流量计算方法是这样的:每冲程的排量×每分钟的动作频率(普通以40计)。
When we choose the pump model according to the outlet pressure of the pump, we need to calculate whether the flow rate of the pump can meet the request. The flow calculation method of the pump is as follows: the displacement per stroke * the action frequency per minute (usually 40).
比如,气动液体增压泵10-4000W003,我们在泵表中查到它每冲程的排量是42.50ml,那么它的流量Q=q×n=42.50ml×40=1700ml/min=1.7L/min。将这个流量与系统需求的流量比较,看能否满足恳求。
For example, pneumatic liquid booster pump 10-4000W003, we found in the pump table that its displacement per stroke is 42.50ml, then its flow Q = Q * n = 42.50ml * 40 = 1700ml / min = 1.7L / min. Compare this traffic with the system demand traffic to see if it can satisfy the request.
假设流量不够,那么,我们再选择一个增压比相近,流量比较大的泵,并核算流量,直到满足系统流量恳求为止。
Assuming that the flow rate is insufficient, then we choose a pump with similar boost ratio and larger flow rate, and calculate the flow rate until the system flow plea is satisfied.
留意,我们所说的流量都是指常压下的流量,行将1分钟内经过泵增压的介质(液体或气体)放在常压下去丈量它的体积。所以,关于气体,我们需求思索预增气压的大小。
Note that what we mean by flow rate is the flow rate at atmospheric pressure. We will measure the volume of the medium (liquid or gas) which is pressurized by the pump within one minute under atmospheric pressure. So, with regard to gases, we need to think about the magnitude of the pre-boost pressure.
比如,我们用空气增压泵将7bar的空气增压至1.2MPa,那么它的流量Q= 7×q×n=7×47.6ml×40=13328ml/min=13.328L/min。
For example, if we use an air booster pump to pressurize 7 bars of air to 1.2 MPa, its flow rate Q= 7*q*n=7*47.6 ml*40=13328 ml/min=13.328 L/min.
