The working principle is as follows:
as shown in connection with figures 4 and 5,
when the oil tank is filled with oil, the oil filling gun 19 is connected to the receiver 8, oil flows out from the oil filling gun 19 and passes through the receiver 8 to the pressure control valve 7, and the oil enters the oil tank body 2 in two paths through the pressure control valve 7; one path enters the oil tank body 2 through a pressure control valve 7 and an oil filling pipe 6, and the other path enters the oil tank body 2 through a control pipeline 9 and a two-stage respirator 11;
first-level gun jump principle: along with the rise of the liquid level of the oil in the oil tank, after the oil reaches the balancing unit 14 of the two-stage breather 11, the balancing unit 14 can rise along with the liquid level of the oil, the balancing unit 14 can drive the internal valve body of the two-stage breather 11 while rising, and then the internal valve body blocks the oil outlet 17 of the two-stage breather 11, and along with the continuous addition of the oil into the two-stage breather 11 to form pressure, the pressure is transmitted to the oil gun 19 through the control pipeline 9, the pressure control valve 7 and the receiver 8, and when the pressure reaches the jump pressure of the oil gun 19, the oil gun 19 realizes the jump automatic stop of oiling;
with the addition of oil, air in the oil tank body 2 is exhausted to the atmosphere through the two-stage breather air holes 13 and the air-permeable hose 10, and the internal pressure of the oil tank body 2 is always consistent with the external atmospheric pressure;
the two-stage gun jump principle: after the oil liquid reaches the oil float 18 of the two-stage breather 11, the oil float 18 can block the breather air hole 13 along with the rising of the liquid level of the oil liquid, and the oil gun 19 is suppressed in the oil tank body 2 to realize jumping and automatic oiling stop when the oil liquid is continuously added.
