As shown in figure 3, the working principle of the negative-pressure balancing and mechanical intelligent liquid supply device:
Negative pressure, which maintains 50-65kPa, in normal infusion pipe can reach pumping requirement, guarantee that dirt can smoothly enter into infusion
Pipe；When initial, negative pressure and cavity one, cavity three, cavity four, the negative pressure of cavity five of compensation voltage stabilizing tank are equal；Pump housing operating
Under state, the negative pressure of compensation voltage stabilizing tank and the negative pressure of cavity one are equal with the negative pressure that the pump housing provides quickly；With the duration of runs
Increasing, liquid-transport pipe-line negative pressure becomes larger, and cavity two becomes larger with perfusion tube pressure difference, when perfusion tube negative pressure reaches 70kpa or more,
Spool is opened, and atmosphere, which enters cavity one, reduces the negative pressure in cavity one, is still atmospheric pressure, cavity one and cavity two in cavity two
Pressure difference reduces, and valve rod one is opened；After valve rod one is opened, the negative pressure in cavity four reduces, and cavity four becomes larger with three pressure difference of cavity, valve
Bar two is opened；After the negative pressure of compensation voltage stabilizing tank is influenced by atmospheric pressure, negative pressure is less than the negative pressure in cavity five, in compensation voltage stabilizing tank
Liquid and the liquid for supplementing joint are injected into the pump housing through cavity five, but due to interface channel two and three liang of interface channel
The precompression difference of damper effect and one 6-10 of spring at port, the valve rod two for supplementing joint open slower, supplement
The time that the liquid injection of connector enters the pump housing enters the time lag of the pump housing than the liquid injection in compensation voltage stabilizing tank；Wherein,
In compensation voltage stabilizing tank when no liquid, supplement connector individually gives pump housing feed flow；As injection liquid enters the pump housing, perfusion tube negative pressure is returned
To 50-65kpa, then spool takes the lead in closing, and the negative pressure of cavity one gradually also returns to 50-65kpa, and valve rod one and valve rod two close
It closes.
Dirt due to the intermittent operating of pump, when high-speed rail and motor-car pull in the state for encountering pump housing stalling, in perfusion tube
It constantly accumulates, the liquid in dirt can enter compensation voltage stabilizing tank through branch pipe 5.
When dirt enters 1 discharge process of the pump housing, it is possible to when causing the pressure in the pump housing 1 excessive, pass through pressure relief valve stem
Pressure release.
