Problems solved by technology

Most of the current gas supply methods use pipeline transportation after decompression, and the operation of equipment and pressure confirmation are controlled by daily spot checks. This method has the following disadvantages: ① Daily spot checks cannot ensure that the gas supply equipment is always under control; ② Air When the compressor fails, it cannot be found in time, which may affect the quality of the sintered product

Embodiment Construction

[0014] The present invention is described in detail with reference to the accompanying drawings, but the protection scope of the present invention is not limited to the following examples, that is, any simple equivalent changes and modifications made based on the scope of the patent application of the present invention and the contents of the description still belong to the patent of the present invention covered.

[0015] like figure 1 As shown, a low-pressure prevention alarm device for an air compressor includes a pressure switch 1 and an alarm device 2. The pressure switch is electrically connected to the alarm device 2 and a 220V power supply 3 through wires 11 respectively, and the pressure measuring head of the pressure switch is connected to the pipeline 12. It is installed between the air outlet 41 of the air compressor 4 and the pressure reducing valve 42 .

[0016] Start the air compressor to make the air pressure reach about 7kgf / cm3.

[0017] Adjust and set the ...

Abstract

The invention discloses a low-pressure prevention alarm device for an air compressor. The low-pressure prevention alarm device comprises a pressure switch and an alarm. The pressure switch is electrically connected with the alarm and a power source through electric wires. A pressure detecting head of the pressure switch is mounted between an air outlet of the air compressor and a reducing valve through a connecting pipeline. By the aid of the low-pressure prevention alarm device for the air compressor, waste of working hours for spot check for multiple times can be effectively reduced, real-time monitoring can be realized, and the low-pressure prevention alarm device plays a significant role in stabilizing product quality and reducing product loss.

Description

technical field [0001] The invention relates to a low-pressure prevention alarm device for an air compressor. Background technique [0002] The gas produced by the air compressor has a wide range of uses, not only as the supporting equipment of various pneumatic tools, but also as raw air in various fields. During the sintering process of the ferrite core, a certain amount of compressed air is required to protect the product to avoid the reduction reaction of the product during the sintering process. When the pressure of the compressed air is too low, the flow rate changes, which ultimately affects the electrical characteristics of the sintered ferrite core. Most of the current gas supply methods use pipeline transportation after decompression, and the operation of equipment and pressure confirmation are controlled by daily inspection. When the compressor fails, it cannot be found in time, and there is a hidden danger that affects the quality of the sintered products. SU...
