Technical Field

The utility model belongs to the technical field of gas compression equipment, a piston air compressor machine is related to, in particular to air compressor machine pump head convenient to oil change.

Background

The air compressor is a device used for compressing gas, which is called an air compressor for short, and is widely applied in the industrial field, the principle of the piston air compressor is that a crank case drives a piston connecting rod component to do reciprocating motion in a cylinder to realize air suction and exhaust processes, the part is called a pump head of the air compressor, engine oil is needed to be used as a lubricant for mechanical motion in the pump head, the service life of the engine oil is limited and needs to be changed regularly, impurity powder and the like can be generated in the operation process of the pump head and deposited at the bottom, for the small air compressor, an oil discharge valve can be arranged at the bottom of the pump head to discharge impurities, but the large industrial-scale air compressor is generally fixed with the ground after being installed and is not easy to detach when being arranged at the bottom, the oil discharge valve is arranged at the side, so that the impurities are easy to accumulate in the pump head, and are, a timed purge is required.

Disclosure of Invention

The utility model aims at the above-mentioned problem that exists among the prior art, provide one kind and be convenient for change machine oil and inside impurity is discharge more easily air compressor machine pump head.

The purpose of the utility model can be realized by the following technical proposal: the utility model provides an air compressor machine pump head convenient to oil change, includes the crankcase and installs a plurality of cylinder on the crankcase, its characterized in that, the inside bottom surface center undercut of crankcase forms a precipitation tank, the tip of precipitation tank is located the side of crankcase and is provided with the oil drain valve, just the precipitation tank to oil drain valve department slope make the oil drain valve be located the below of crankcase.

In the air compressor pump head convenient for oil change, an oil level valve is arranged above the oil drain valve on the crankcase.

In the above-mentioned air compressor pump head convenient to change oil, the terminal surface of crankcase is provided with two and is streamlined reinforcing plates rather than formula structure as an organic whole and edge, oil drain valve and oil level valve all be located the reinforcing plate.

In the above-mentioned air compressor pump head convenient to change oil, the bottom surface of crankcase and the two panels that the precipitation tank is connected all are ARC structure.

In the above-mentioned air compressor pump head convenient to change oil, the top of crankcase is provided with the inlet port with inside intercommunication.

In the above-mentioned air compressor pump head of being convenient for change oil, the quantity of cylinder is 2 or 3.

In this air compressor machine pump head, mainly through seting up the precipitation tank in the crankcase bottom surface, the vibrations that the impurity that the inside friction of pump head produced sent when its moves will pile up in the precipitation tank to through the oil drain valve of opening its tip when changing oil, impurity will be discharged along with used oil, and is further, in order to make the discharge that impurity can be more thorough, the precipitation tank is to the slope of oil drain valve department.

Compared with the prior art, this air compressor pump head has following advantage:

1. impurities in the pump head are easy to discharge through the design of the settling tank, and the oil is changed more thoroughly, so that the purity of the changed engine oil is higher;

2. make the pump head more pleasing to the eye through streamlined reinforcing plate to can not reduce the intensity of crankcase after setting up oil drain valve and oil level valve.
