Embodiment Construction

[0024] In order to make the technical problems, technical solutions and beneficial technical effects to be solved by the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and multiple exemplary embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the protection scope of the present invention.

[0025] The principle of the present application will be described in detail below by taking a screw air compressor as an example. However, those skilled in the art should understand that the present application is not only applicable to screw air compressors, but also applicable to any air compressors using lubricating oil.

[0026] Screw compressors consist of a pressure vessel, such as an oil tank or an oil separator, in which lubricating oil collects to form an oil pool. Screw compressors are used, fo...

Abstract

The invention provides an oil level gauge for an air compressor, the oil level gauge comprises a shell (1), the shell (1) delimits a cavity and is provided with an observation window for observing the oil level, a high oil level marking line (11) and a low oil level marking line (12), and the shell (1) is provided with two opposite end parts in the longitudinal direction of the observation window; a first tube (2) connected to the housing (1) at one end of the housing (1); and a second tube (3) connected to the housing (1) at the other end of the housing (1) wherein the first tube (2) and / or the second tube (3) extend along a curved path and / or the first tube (2) and / or the second tube (3) can extend along a curved path. The invention further provides the air compressor. By means of the oil level indicator, the shape and size of the shell of the oil level indicator and the installation position of the shell on the oil tank can be less limited. And particularly, the oil level gauge can be modified at low cost.

Description

technical field [0001] The invention relates to an oil level gauge for an air compressor and an air compressor. Background technique [0002] In air compressors, such as screw compressors, lubricating oil is usually used to lubricate and cool various components in the air compressor. The normal operation of the oil supply system is directly related to the normal operation and service life of the air compressor. If, for example, due to a malfunction of the lubricating oil circulation system, the amount of oil in the air compressor is too low and the air compressor continues to operate, it will eventually lead to failure and damage of the air compressor. [0003] In order to check whether the oil quantity of the air compressor is sufficient, the usual practice is to observe it through the oil level mirror of the air compressor when the oil quantity of the air compressor is checked. The oil level mirror is mounted on, for example, the casing of the oil tank of the air compress...
