为了解决S7620内螺纹磨床静压轴承主轴漏油问题,我们通过对该机床的液压系统的分析,找出了漏油的关键,自制了液压阀,解决了漏油问题。 S7620磨床原结构中,当关闭双联泵的左泵时,右泵也同时关闭,这时,蓄能器的油继续向静压轴承供油,油返不回油箱,就从静压轴承两端挤出,出现漏油现象。改进后的供油系统图见图1,在双联泵回油的右泵的抽
In order to solve the S7620 internal thread grinder hydrostatic bearing spindle oil leakage problem, we analyzed the hydraulic system of the machine tools to identify the key to the oil spill, made a hydraulic valve to solve the oil spill problem. S7620 grinder original structure, when the double pump is closed when the left pump, the right pump is also closed at this time, the accumulator oil continues to supply hydrostatic bearings, the oil does not return to the tank, the static pressure from the two bearings Extruded side, there oil leakage phenomenon. Improved oil supply system diagram shown in Figure 1, the pump in the double pump back to the pumping of the right pump
