              濟南液壓升降機http://www.pzqsb.com/液壓閥是任何一個液壓系統的重要組成部分,其選型合理與否,對整個液壓系統的工作可靠性、制造經濟性、維修方便等性能有著至關重要的影響。

              1、濟南液壓升降機液壓閥選擇時按系統的的拖動與控制功能要求,合理選擇液壓閥的機能和品種,并與液壓泵、執行器和輔助元件等一起構成完整的液壓回路與系統原理圖。
              Jinan hydraulic lift hydraulic valve selection by dragging the control system functional requirements, a reasonable choice of hydraulic valve function and varieties, and with hydraulic pumps, actuators and auxiliary components together constitute a complete hydraulic circuit and system schematics.

              2、濟南液壓升降機液壓閥應該優先選用現有標準定型系列產品,除非不得已才自行設計專用液壓控制閥。
              Jinan hydraulic lift hydraulic valve should be preferred standard stereotypes existing products, unless compelled to design their own special hydraulic control valve.

              3、濟南液壓升降機液壓閥選擇時根據系統工作壓力與通過流量,并考慮閥的類型、安裝連接方式、操縱方式、工作介質。尺寸與重量、工作壽命、經濟性、適應性與維修方便性、貨源及產品歷史等,從相關的設計手冊或產品樣本中選擇。
              Jinan hydraulic lift system operating according to the hydraulic pressure and flow through the valve selection, and considering the type of valve, installation connections, manipulation, working media. Size and weight, working life, the economy, adaptability and ease of maintenance, supply and product history, choose from the relevant design manuals or product samples.

              4、濟南液壓升降機液壓閥公稱壓力和額定流量的選擇
              各液壓控制閥的公稱壓力和額定流量一般應與其工作壓力和工作壓力和工作流量相近。對于可靠性能要求較高的系統,閥的公稱壓力應高出其工作壓力較多。一般而言,閥的公稱壓力大于或等于系統工作壓力是比較安全和合理的選擇。系統工作流量若與閥的額定流量接近,顯然是最經濟、合理的匹配;如果額定流量小于工作流量,則易引起液壓卡緊和液動力,并對閥的工作品質產生不良影響。對于系統中的順序閥和減壓閥,其工作流量不應遠小于額定流量,否則易產生振動或其它不穩定現象。對于流量閥,應注意最小穩定流量。
              Each hydraulic control valve nominal pressure and rated flow should generally be their job stress and job stress and work flow similar. For high system reliability requirements, the valve should be higher than the nominal working pressure more. Nominal general, the valve is greater than or equal to the system pressure is relatively safe and reasonable choice. If the system work flow close to the rated flow valves, is clearly the most economical and reasonable match; if less than the rated flow of work flow, is easy to cause the hydraulic clamping and hydraulic power, and adversely affect the quality of the valve. In order for the system and pressure reducing valve, its work should be much less than the rated flow of traffic, or easy to produce vibrations or other instability. For flow valve, should pay attention to the smallest stable flow.
