對于單級增壓泵，根據增壓比的不同，入口壓力對流量的影響很大。在相同增壓比下，一定范圍內進(jìn)口壓力越高，輸出流量越大。流量影響很大，對增壓泵的壽命很有幫助。
For the single-stage booster pump, the inlet pressure has a great influence on the flow according to the different pressurization ratio. Under the same boost ratio, the higher the inlet pressure within a certain range, the greater the output flow. The flow has a great impact on the service life of the booster pump.
入口壓力越高，輸出流量越大，增壓泵的工作頻率會(huì )大大縮短，從而影響增壓泵的壽命。反之，由于入口壓力低，增壓泵的工作時(shí)間會(huì )變長(cháng)，需要多次工作才能提高壓力，氣體增壓泵的壽命就會(huì )縮短。
The higher the inlet pressure, the greater the output flow, and the working frequency of the booster pump will be greatly shortened, which will affect the service life of the booster pump. On the contrary, due to the low inlet pressure, the working time of the booster pump will be longer, and it needs to work for many times to increase the pressure, and the service life of the gas booster pump will be shortened.
對于兩級增壓泵，對進(jìn)口壓力有很大的要求。以FeintZTT40為例，如果現場(chǎng)加壓氣體為15bar，則客戶(hù)需要將壓力減壓10bar進(jìn)行加壓。如果在高壓和氣壓范圍內，泵將停止工作。壓力在10bar以?xún)葔毫υ礁撸髁吭酱蟆?/div>
For two-stage booster pump, there are great requirements for inlet pressure. Take feintztt40 as an example. If the on-site pressurized gas is 15bar, the customer needs to reduce the pressure to 10bar for pressurization. If it is within the range of high pressure and air pressure, the pump will stop working. When the pressure is within 10bar, the higher the pressure, the greater the flow.
入口壓力會(huì )影響工廠(chǎng)車(chē)間的生產(chǎn)力。建議在有條件的前提下，預壓氣體對氣體增壓泵有很大幫助。
The inlet pressure will affect the productivity of the plant. It is suggested that the pre pressurized gas is of great help to the gas booster pump on the premise of conditions.
對大多數泵來(lái)說(shuō)，加大進(jìn)、出口管徑的目的是降低管內流體的流速，減小管的阻力降低泵的功耗，但管徑的增加是以增加管子的投資成本為代價(jià)的。這樣，對于長(cháng)輸泵出口的管道，可以考慮適當加大管徑，以降低阻力降，而對于短輸管道，可以忽略不計。
For most pumps, the purpose of increasing the inlet and outlet pipe diameter is to reduce the flow rate of fluid in the pipe, reduce the resistance of the small pipe and reduce the power consumption of the pump, but the increase of pipe diameter is at the cost of increasing the investment cost of the pipe. In this way, for the pipeline at the outlet of long-distance transmission pump, it can be considered to appropriately increase the pipe diameter to reduce the resistance drop, while for short-distance transmission pipeline, it can be ignored.
因為泵進(jìn)口輸送的物料為液化氣，溫度接近沸點(diǎn)。對于容易產(chǎn)生氣蝕的材料，如吸入位置比較低的材料，可考慮加大泵進(jìn)水管的直徑，以減少阻力降，避免泵發(fā)生氣蝕。
Because the material delivered at the pump inlet is liquefied gas, the temperature is close to the boiling point. For materials prone to cavitation, such as those with low suction position, consider increasing the diameter of the pump inlet pipe to reduce the resistance drop and avoid cavitation of the pump.
設備本身應配備有效的防泄漏設施，確保有害物質(zhì)不泄漏。化學(xué)品或油品為新品種、新的，需事先經(jīng)過(guò)質(zhì)量行政管理部門(mén)批準。應為可能泄漏的設備提供防泄漏托盤(pán)。通知設施部門(mén)并發(fā)布計劃。排污計劃需事先經(jīng)質(zhì)量行政管理部門(mén)批準。
The equipment itself shall be equipped with effective anti leakage facilities to ensure that harmful substances do not leak. If chemicals or oil products are new varieties or brands, they shall be approved by the quality administrative department in advance. Leak proof trays shall be provided for equipment that may leak. Inform the facility department and issue the plan. The pollution discharge plan shall be approved by the quality administrative department in advance.
一般來(lái)說(shuō)，應盡可能使用能耗效率高的部件。在設計整個(gè)
氣液增壓泵系統時(shí)，應計算系統的所有能耗。所有電氣設備應在生產(chǎn)間隔和待機模式下提供可選的手動(dòng)模式。自動(dòng)運行時(shí)還可以有模式。當使用氣體和真空系統時(shí)，應控制能源浪費。相關(guān)措施應在系統技術(shù)參數要求中注明。在安裝和調試過(guò)程中，盡量防止壓縮空氣泄漏。
Generally speaking, components with high energy consumption efficiency should be used as much as possible. When designing the whole gas-liquid booster pump system, all energy consumption of the system shall be calculated. All electrical equipment shall be provided with optional manual energy-saving mode in production interval and standby mode. There can also be energy-saving mode during automatic operation. When using gas and vacuum systems, energy waste should be controlled. Relevant measures shall be indicated in the technical parameter requirements of the system. During installation and commissioning, try to prevent compressed air leakage.
