Abstract
The utility model provides an air exhaust device for a lubricating oil station with small turbines. The device is capable of discharging the air in an oil pump automatically and ensuring that the oil pump can work normally. The device comprises at least one pair of oil pumps and outlet check valves, wherein each oil pump is arranged on an oil box. Oil pump air exhaust pipes are arranged between the oil pumps and the outlet check valves. The oil pump air exhaust pipes are provided with air exhaust restriction orifices. Normally open type pipelines are arranged between the outlets of the oil pumps and the outlet check valves in a tubular mode, wherein the normally open type pipelines are provided with air exhaust valves and the air exhaust restriction orifices, and therefore the air can be exhausted when the oil pumps start and the oil pumps can operate normally. The air exhaust restriction orifices can restrict the exhausted oil mass, and therefore lubrication pressure and oil supplying mass are not affected. The air exhaust valves can be used to clean the air exhaust restriction orifices without affecting the normal operation of the oil pumps when the air exhaust restriction orifices are blocked. The air can be exhausted without any restriction at any time when the oil pumps start, and therefore the oil pumps can start and work normally.
Description
Technical field
The utility model relates to a kind of lubricating oil station equipment, especially a kind of little machine lubricating oil station venting gas appliance.
Background technique
The oil discharging device of small turbine lubricating oil station comprises a plurality of oil pumps, and the outlet of every oil pump only is provided with the outlet non-return door.When starting and the problem low or that do not oil that when oil pump is switched, often occurs exerting oneself, need to be undertaken to work after the exhaust by dismounting outlet nut.
The model utility content
The utility model provides a kind of can discharge air in the oil pump automatically, guarantees the little machine lubricating oil station venting gas appliance of the normal operation of oil pump.
Realize the little machine lubricating oil station venting gas appliance of the utility model purpose, comprise at least one pair of oil pump and the outlet non-return door that are positioned on the fuel tank, be provided with the emptying tracheae of oil pump in the middle of described oil pump and the outlet non-return door, the emptying tracheae of described oil pump is provided with the air-discharging restricting orifice.
The emptying tracheae of described oil pump is provided with the air-discharging valve, and described air-discharging valve is positioned at the place ahead of air-discharging restricting orifice.
Described oil pump and outlet non-return Men Weisan pair.
The beneficial effect of little machine lubricating oil station venting gas appliance of the present utility model is as follows:
Little machine lubricating oil station venting gas appliance of the present utility model, pipeline is provided with the pipeline open in usual of air-discharging valve and air-discharging restricting orifice between the outlet of oil pump and outlet non-return door, can with Bas Discharged when pump start, guarantee the normal operation of pump.Restricting orifice can limit the oil mass of discharge simultaneously, does not affect lubrication pressure and fuel feeding oil mass; The air-discharging valve also can be used for cleaning air-discharging restricting orifice after orifice plate stops up, normally do not move and do not affect oil pump.Bas Discharged in the time of can be at any time with pump start is not restricted, and guarantees the normal startup operation of oil pump.
Description of drawings
Fig. 1 is the structural representation of little machine lubricating oil station venting gas appliance of the present utility model.
Embodiment
As shown in Figure 1, little machine lubricating oil station venting gas appliance of the present utility model, comprise the three pairs of oil pumps 2 and the outlet non-return door 3 that are positioned on the fuel tank 1, be provided with the emptying tracheae 4 of oil pump in the middle of described oil pump 2 and the outlet non-return door 3, be connected with respectively air-discharging valve 5 and air-discharging restricting orifice 6 on the emptying tracheae 4 of described oil pump.
The working principle of little machine lubricating oil station venting gas appliance of the present utility model enters lower:
Because all there are air in oil pump inlet duct and outer pipe, behind the pump start, because the gas compression state labile causes exporting the pressure that does not reach unlatching outlet non-return door, entrance can't form effective vacuum and cause oil pump not oil.After installing this pipeline open in usual with air-discharging valve and air-discharging restricting orifice additional, can guarantee to form vacuum in the oil pump ingress along through discharge herein through the air of oil pump compression, made operation of oil pump normal.
Embodiment recited above is described preferred implementation of the present utility model; be not that scope of the present utility model is limited; design under the spiritual prerequisite not breaking away from the utility model; various distortion and improvement that the common engineers and technicians in related domain make technical solutions of the utility model all should fall in the definite protection domain of claims of the present utility model.
Claims (3)
1. one kind little machine lubricating oil station venting gas appliance is characterized in that: comprise at least one pair of oil pump and the outlet non-return door that are positioned on the fuel tank, is provided with the emptying tracheae of oil pump in the middle of described oil pump and the outlet non-return door, the emptying tracheae of described oil pump is provided with the air-discharging restricting orifice.
2. little machine lubricating oil station venting gas appliance according to claim 1, it is characterized in that: the emptying tracheae of described oil pump is provided with the air-discharging valve, and described air-discharging valve is positioned at the place ahead of air-discharging restricting orifice.
