齒輪油泵流量大小與使用系統的有什么關系
齒輪油泵流量大小與使用系統的有什么關系。 The gear pump is generally used as fuel capacity is according to the system the required oil quantity to select, emissions will cause waste, emissions is too small can not meet the use demand cause accidents, such as for lubrication of gear pump. General gear oil pump capacity should be greater than the required oil quantity is ten percent to twenty. If the gear oil pump capacity is too small will cause the system pressure is slow, not even up to the required pressure, and the capacity is too large, will cause the system to boost too fast, the pressure is too high and difficult to control, to the relief, relief measures such as increasing the operation cost, has great power consumption.General now gear oil pump inspection need from the following several aspects to consider:
1 medium viscosity, the conveying pump.Medium temperature is
2, the normal operation of the pump.
3, the reasonable according to the pipeline resistance and line loss calculation of pipe length, diameter, elbow reasonable quantity of the normal work of the gear oil pump.
4, dielectric properties.
一般作為供油用的齒輪油泵的排量是按系統所需油量來選擇的，排量過大會造成浪費，排量過小滿足不了使用需量會造成事故，如供潤滑用的齒輪油泵。一般選擇齒輪油泵的排量應大于所需油量的百分之十到二十之間。另外如果齒輪油泵排量過小還會造成系統升壓慢，甚至達不到所需壓力，而排量過大又會造成系統升壓過快，壓力過高而難以控制，不得不釆用溢流，減壓等措施增加了運行成夲，造成了較大的無用功耗。
一般現在齒輪油泵檢查時需要從以下幾個方面來考慮：
1、泵所輸送的介質粘度。
2、泵正常工作時的介質溫度。
3、合理根據管路長短、直徑大小、彎頭數量合理的計算出齒輪油泵正常工作時的管路阻力和管路損失。
4、介質屬性。
