Abstract

The utility model relates to a diaphragm compressor, in particular to an oil supply system of a diaphragm compressor, which comprises an oil pump, wherein an oil inlet of the oil pump is communicated with the bottom of a crankcase through a pipeline; different from the prior art: the pipeline is connected with a swing check valve in series. Compared with the prior art, the utility model discloses swing check valve can block the hydraulic oil among the pipe-line system after the oil pump stop work and get back to the crankcase body, keeps having hydraulic oil among the pipe-line system, can inhale oil fast when the oil pump of being convenient for restarts.

Description

Diaphragm compressor oil supply system

Technical Field

The utility model relates to a diaphragm compressor specifically is a diaphragm compressor oil feeding system.

Background

The diaphragm compressor mainly comprises a motor, a base, a crankcase, a crankshaft connecting rod motion mechanism, a cylinder body part, an oil-gas pipeline, an electric control system and some accessories. The existing oil supply system communicated with the crankcase comprises an oil pump, wherein the oil pump is communicated with the crankcase through a pipeline, when the oil pump stops working, working oil in the pipeline flows to the crankcase under the action of gravity, the pipeline at least higher than the liquid level of the working oil in the crankcase is filled with the working oil, and when the oil pump is restarted, the oil pump can absorb the oil only by emptying air in an empty pipeline without the working oil, so that the normal work of the diaphragm compressor is influenced.

SUMMERY OF THE UTILITY MODEL

For overcoming one of prior art's defect or defect, the utility model discloses a diaphragm compressor oil feeding system, the technical scheme who takes is:

an oil supply system of a diaphragm compressor comprises an oil pump, wherein an oil inlet of the oil pump is communicated with the bottom of a crankcase through a pipeline; different from the prior art: the pipeline is connected with a swing check valve in series.

Further, a Y-shaped rotary filter is connected in series on the pipeline.

Furthermore, two ports of the tee joint are connected in series on the pipeline, and the third port of the tee joint is plugged by a plug.

Compared with the prior art, the utility model discloses swing check valve can block the hydraulic oil among the pipe-line system after the oil pump stop work and get back to the crankcase body, keeps having hydraulic oil among the pipe-line system, can inhale oil fast when the oil pump of being convenient for restarts.

Fig. 1 is a schematic structural diagram of the present invention.

Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention.

In the description of the present invention, it should be noted that unless otherwise explicitly stated or limited, the terms "mounted," "connected" and "connected" are to be understood broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected, mechanically connected, electrically connected, directly connected, indirectly connected through an intermediate medium, or connected between two elements. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

As shown in the figure, the oil supply system of the diaphragm compressor comprises an oil pump 8, an oil inlet of the oil pump is connected with a horizontal port of a tee joint 6 through a horizontal clamping sleeve joint 7, a lower port of the tee joint 6 is connected with the upper end of a vertical pipeline 5, an upper port of the tee joint 6 is blocked by a plug 9, the lower end of the pipeline 5 is connected with an upper port of a 90-degree elbow 4, the horizontal port of the elbow 4 is connected with one end of a Y-shaped filter 3 which is horizontally arranged, the other end of the Y-shaped filter 3 is connected with one end of a swing check valve 2, and the other end of the swing check valve 2 is communicated with the bottom of a crankcase through a butt wire 1.

The swing check valve is an automatic valve used for preventing media from flowing backwards on a one-way flow pipeline, the valve is automatically opened or closed by the flowing pressure of the pipeline media, and the swing check valve only allows the media to flow in one direction, so that the media can be effectively prevented from flowing backwards, and accidents are prevented. The utility model discloses a swing check valve can stop the hydraulic oil among the pipe-line system after the oil pump stop work and get back to the crankcase body, keeps having hydraulic oil among the pipe-line system, can inhale oil fast when the oil pump of being convenient for restarts.

The Y-shaped filter can filter the working oil in the system when the system works normally. The tee joint has two ways which are connected with the pipeline, the plug is detached from the way without pipeline connection before the whole diaphragm compressor starts to test and run, the pipeline system is filled with hydraulic oil from the way, and the plug is installed after the pipeline system is filled with the hydraulic oil, so that the oil pump can conveniently absorb the oil.

The invention is not described in detail in the prior art or in the common general knowledge.
