Abstract
The utility model discloses an air compressor machine lubricating structure, which comprises a housing. Casing inner chamber upper portion is the air chamber, and casing inner chamber lower part is the grease chamber, has seted up gas outlet and air inlet at the top of casing, sets up oil inlet and oil return opening on the lateral wall of casing as the inner chamber lower part of grease chamber, and the oil inlet is located the top of oil return opening. The lateral wall of casing as the inner chamber lower part of grease chamber on set up the second oil inlet, this second oil inlet and engine oil drain pan oil inlet intercommunication. Because the utility model discloses set up the second oil inlet on the lateral wall of casing as the inner chamber lower part of grease chamber, this second oil inlet and engine oil drain pan oil inlet intercommunication, the air compressor machine grease chamber forms a bleeder vent like this, just can not produce negative pressure suck -back machine oil, and the unnecessary machine oil that splashes in the grease chamber flows back in the oil pan of engine for the piston removes smooth and easy more, installation nature height.
Description
Technical field
This utility model relates to engineering machinery field, particularly relates to a kind of air compressor machine lubrication system.
Background technology
The lubrication of air compressor machine is that the machine oil utilizing electromotor lubricates.As shown in Figure 1, machine oil is by oil inlet pipe and by the grease chamber 2 ' of oil-in 11 ' the entrance air compressor machine casing 1 ' in air compressor machine casing 1 ', being lubricated air compressor machine inner member in splash lubrication mode, fluid flows back to engine sump tank after being entered oil return pipe by the oil return opening 12 ' in air compressor machine casing again by deadweight.The lubrication strategies of this air compressor machine commonly used easily occurs altering oil phenomenon, because the piston in air compressor machine moves up and down 4 ' repeatedly, when piston 4 ' moves upward, negative pressure it is easily generated in grease chamber 2 ', fluid easily from oil return opening 12 ' in gap suck-back air inlet chamber 3 ' with air compressor cylinder body inwall of piston 4 ', it is easily caused brakes internal component damage, affects braking.
Summary of the invention
The purpose of this utility model is to provide a kind of piston to move air compressor machine lubrication system smooth and easy, that installation is high.
For achieving the above object, technical solution of the present utility model is:
This utility model is a kind of air compressor machine lubrication system, including casing；Chassis cavity top is air chamber, and chassis cavity bottom is grease chamber, offers gas outlet and air inlet at the top of casing, offers oil-in and oil return opening in casing as on the sidewall of the inner chamber bottom of grease chamber, and oil-in is positioned at the top of oil return opening；Described casing offers the second oil-in as on the sidewall of the inner chamber bottom of grease chamber, and this second oil-in connects with engine sump tank oil-in.
Described oil-in is at engine motor oil ullage.
After using such scheme, owing to this utility model offers the second oil-in in casing as on the sidewall of the inner chamber bottom of grease chamber, this second oil-in connects with engine sump tank oil-in, so air compressor machine grease chamber forms an air-vent, negative pressure suck-back machine oil would not be produced, in grease chamber splash unnecessary machine oil be back in the oil sump of electromotor so that piston move more smooth and easy, installation is high.
With specific embodiment, this utility model is further described below in conjunction with the accompanying drawings.
Accompanying drawing explanation
Fig. 1 is the structural representation commonly using air compressor machine；
Fig. 2 is structural representation of the present utility model.
Detailed description of the invention
As in figure 2 it is shown, this utility model is a kind of air compressor machine lubrication system, including casing 1.
Described casing 1 inner chamber top is air chamber 2, casing 1 inner chamber bottom is grease chamber 3, gas outlet 11 and air inlet 12 is offered at the top of casing 1, in casing 1 as offering oil-in 13 and oil return opening 14 on the sidewall of the inner chamber bottom of grease chamber 3, oil-in 13 is positioned at the top of oil return opening 15 and at engine motor oil ullage.
Described casing 1 is as offering the second oil-in 15 on the sidewall of the inner chamber bottom of grease chamber 3, this second oil-in 15 connects with engine sump tank oil-in.
Operation principle of the present utility model:
Due in casing 1 as offering the second oil-in 15 on the sidewall of the inner chamber bottom of grease chamber 3, this second oil-in 15 connects with engine sump tank oil-in, so air compressor machine grease chamber 3 forms an air-vent, negative pressure suck-back machine oil would not be produced in grease chamber 3, the unnecessary machine oil splashed in grease chamber is back in the oil sump of electromotor so that piston moves more smooth and easy.
Emphasis of the present utility model is that offers the second oil-in in casing as on the sidewall of the inner chamber bottom of grease chamber.
The above, it is only this utility model preferred embodiment, therefore can not limit, with this, the scope that this utility model is implemented, the equivalence change i.e. made according to this utility model claim and description with modify, all should still belong in the range of this utility model patent contains.
Claims (2)
