Abstract

The utility model discloses a pneumatic control switch of an air compressor. The pneumatic control switch comprises a contactor Km1 and a contactor Km2, wherein the contactor Km1 and the contactor Km2 are connected with a motor in the air compressor through a thermal relay FR after being connected in parallel; and the normally open contact of the contactor Km1 and the normally closed contact of the contactor Km2 are connected in series. The control switch disclosed by the utility model can be used for accurately controlling the air pressure of the air compressor.

Description

The air compressor baroswitch
Technical field
The utility model relates to a kind of air compressor baroswitch.
Background technique
Pressurized air since its Clear & Transparent, harmless pollution-free, be safe from danger, be prone to characteristics such as conveying, have the excellent application performance ability.Pressurized air is in commercial production, for example in iron and steel, oil, rock gas, food, weaving, semiconductor, liquid crystal, medicine, medical treatment, analytical instrument, clean etc. in the industry and all have a wide range of applications in the scientific experiment.It provides power source for various pneumatic tools and air control unit, also can be used as the part of production technology, as stirring material, and liquid waterfall gas and combustion-supporting etc.
At present, air compressor generally relies on the GYD-20-6A Pnenmatic automatic switch to regulate pressure, and when pressure reached certain value, the motor in the air compressor stopped automatically; At this moment pressurized air consumes from the place of proper functioning on the one hand, leaks and loses from baroswitch on the one hand, causes unnecessary energy loss and unnecessary noise, and causes air pressure control inaccurate; This is not only unfavorable to producing, but also is easy to damage baroswitch.
Summary of the invention
The technical problem that the utility model will solve provides a kind of air compressor baroswitch that can accurately control air pressure.
In order to solve the problems of the technologies described above, the utility model provides a kind of air compressor baroswitch, comprises contactor Km 1With contactor Km 2, contactor Km 1With contactor Km 2Parallel connection back links to each other with motor in the air compressor through thermorelay FR; Contactor Km 1Normally opened contact and contactor Km 2Normally-closed contact series connection.
The air compressor baroswitch of the utility model has the following advantages:
1, Safety performance height, energy-conserving and environment-protective, noise free;
2, can accurately control air pressure;
3, can not produce the leakage of gas.
Description of drawings
Below in conjunction with accompanying drawing the embodiment of the utility model is done further explain.
Fig. 1 is the electrical schematic of the air compressor baroswitch of the utility model.
Embodiment
Embodiment 1, Fig. 1 have provided a kind of air compressor baroswitch, comprise the contactor Km of parallel connection 1With contactor Km 2, the contactor Km after the above-mentioned parallel connection 1With contactor Km 2Link to each other with motor in the air compressor through thermorelay FR.Contactor Km 1Normally opened contact and contactor Km 2Normally-closed contact series connection.
Contactor Km 1Corresponding is the low pressure of air compressor, and when compressor was lowpressure, the moving pin on the pressure indicator of exhaust outlet of compressor contacted with hypobaric pointer, makes contactor Km 1Coil gets electric adhesive, makes the motor rotation in the air compressor normal.
Contactor Km 2Corresponding is the high pressure of air compressor, and when compressor was highpressure, the moving pin on the pressure indicator of exhaust outlet of compressor contacted with anticyclonic pointer, makes contactor Km 2Thereby coil gets electric releasing contactor Km 2Self-locking, the motor in the air compressor is quit work.
At last, it is also to be noted that what more than enumerate only is a specific embodiment of the utility model.Obviously, the utility model is not limited to above embodiment, and many distortion can also be arranged.All distortion that those of ordinary skill in the art can directly derive or associate from the disclosed content of the utility model all should be thought the protection domain of the utility model.
