Description
Technical field
This utility model belongs to vacuum pump technology field, relates to the automatic oil-way control system of a kind of vacuum pump.
Background technology
In the oil circulation of vacuum pump, fluid is stored in fuel tank by concentration, has shoe cream room in vacuum pump, and vacuum pump is high
The air inlet of the air vent of vacuum chamber slide valve assembly, the oil-in of fine vacuum chamber slide valve assembly and coarse vacuum chamber slide valve assembly all with
Shoe cream room connects, and the oil in fuel tank enters in shoe cream room, then it is sliding to enter fine vacuum chamber from the oil-in of fine vacuum chamber slide valve assembly
In valve module being lubricated guiding valve, the air vent of fine vacuum chamber slide valve assembly is used for discharging air-fuel mixture gas, the gas of discharge
Body and oil enter the air inlet of coarse vacuum chamber spool valve combinations, and then the air vent from coarse vacuum chamber spool valve combinations drains into fuel tank, warp
After Oil-gas Separation, gas drains into the external world from air vent, and oil is then stored in Recycling in fuel tank.In use in order to avoid because of
Too much, oil level is too high for oil in shoe cream room, and it is true that oil enters slide valve assembly from the air inlet of coarse vacuum chamber slide valve assembly and causes
The negative effect that empty pump noise is high, motor load is big, it is therefore desirable to amount oily in controlling to enter shoe cream room in fuel tank.
The most commonly used connectivity part between shoe cream room and fuel tank arranges the structure of electromagnetic valve or hands dribble valve and comes real
Existing.The structure of electromagnetic valve is the switch that the directly linkage by the time relay or with motor controls valve, therefore shoe cream room
Interior oil level controls the most accurate.Although this structure can substantially realize controlling oil and enter the amount in shoe cream room, but electromagnetic valve is being grown
Time easily breaks down after using, and needs often to safeguard or change, and use cost is higher.The structure of manual ball valve is to pass through
Artificial mode controls the switch of valve, and therefore in shoe cream room, oil level controls the most not accurate, and the numbest
Tired, often occur that valve is forgotten out and the dry grinding phenomenon or the valve that cause pump piston chamber oil-free and cause are forgotten to close and cause pump
Piston chamber oil too much causes that pump noise is big, load weight, shut down after the phenomenon such as starting difficulty.
Summary of the invention
The purpose of this utility model is to there are the problems referred to above for existing technology, it is proposed that the oil circuit of a kind of vacuum pump is certainly
Autocontrol system, this utility model solves the technical problem that it is to use lower-cost frame for movement to realize being automatically replenished shoe cream room
