Y236刨齿机油泵开启后,较长时间不能供油,或供入上部分油槽的油断断续续,使机床不能很好地正常润滑。为此,我们在油泵与滤油网之间加入一个自制的单向阀,如图1所示。单向阀的尺寸与形状如图2。将单向阀体镶入吸油管管口处,在油管上方距钢球尺寸大约为钢球的一倍左右铆入一个挡销,防止钢球吸入到泵体内。 Y236 gear cutting machine oil pump is turned on for a long time can not supply oil, or for the upper part of the tank oil intermittent, so that the machine can not properly normal lubrication. To this end, we add a homemade check valve between the pump and the oil filter, as shown in Figure 1. Check valve size and shape shown in Figure 2. The one-way valve body set in the mouth of the suction pipe at the pipe above the ball from the ball size is about double the riveting into a stopper pin to prevent the steel ball into the pump body.
