Description
Technical Field
The utility model belongs to car power takeoff field relates to the oiling equipment, especially a vacuum oiling device for power takeoff.
Background
The existing oil injection equipment adopts a natural oil injection method to inject oil, the oil injector is complex to operate, and moreover, because an oil filling port of a power takeoff is small, the air exhaust is difficult during oil injection, the oil injection time is long, the workload is large, the efficiency is low, the production beat cannot be met, and the requirement of capacity cannot be met.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome prior art's weak point, provide a vacuum oiling device for power takeoff that can quick oiling, improve work efficiency.
The utility model provides a technical scheme that technical problem adopted is:
the utility model provides a vacuum oiling device for power takeoff, includes distribution piece and respectively with the oil gun, notes oil pipe and the evacuation pipe that distribution piece intercommunication is connected, notes oil pipe connection oil pump, evacuation pipe connection vacuum pump, install oiling solenoid valve and oil circuit distributor on annotating oil pipe, oil circuit distributor connects oil feed interface and oil return interface, installs the evacuation solenoid valve on the evacuation pipe.
Further, a vacuum pressure sensor is mounted on the distribution block.
Further, a temperature sensor is attached to the oil passage distributor.
And, a seal ring is mounted at the outlet end of the grease gun.
Moreover, the oil injection solenoid valve is an external pilot type solenoid valve.
The utility model has the advantages that:
1. the utility model discloses a sealing washer seals the power takeoff oil filler hole, appears the gas leakage condition when effectively preventing the evacuation, makes the inside negative pressure that can produce rapidly of product.
2. The utility model discloses installed the solenoid valve respectively on evacuation pipeline and oiling pipeline, improved degree of automation, reduced operating personnel's work load.
3. The utility model discloses install vacuum pressure sensor on the distribution piece, real-time supervision product internal pressure prevents that vacuum from surpassing product pressure resistance and damaging the product, can adjust the size of oiling volume according to the size of vacuum simultaneously, prevents that the oiling from overfilling.
4. The utility model discloses be provided with oil temperature sensor on oil circuit distributor, install into oil pipe and return oil pipe in order to keep the mobility of lubricating oil at oil circuit distributor simultaneously, prevent that lubricating oil from leading to the oiling difficulty because of the temperature is low.
