Abstract
The utility model discloses a low-pressure preventing alarm device for an air compressor. The low-pressure preventing alarm device for the air compressor comprises a pressure switch and an alarm device body. The pressure switch is electrically connected with the alarm device body and a power source through wires. A pressure measurement head of the pressure switch is installed between an air outlet of the air compressor and a reducing valve through a connecting pipeline. According to the arrangement of the low-pressure preventing alarm device for the air compressor, man-hours of multiple times of point inspection can be effectively reduced, real-time monitoring can be achieved, and the low-pressure preventing alarm device for the air compressor has remarkable effects on stabilization of product quality and reduction of product losses.
Description
Technical field
The utility model relates to a kind of air compressor low pressure prevention emergency alarm.
Background technique
The gas that air compressor produces is of many uses, both can be used as all kinds of air tool corollary equipments, can be applied to multiple field as raw air again.Need a certain amount of pressurized air to protect in the sintering process of FERRITE CORE, avoid product in sintering process, to produce reduction reaction.When compressed-air actuated hypotony, flow can change thereupon, finally can influence the electrical characteristic of the FERRITE CORE of institute's sintering.Present plenum system adopts decompression back line transportation mostly, and equipment operation and pressure confirm to adopt the method for daily spot check to carry out management and control, and there is following shortcoming in the method: 1. daily spot check can't guarantee that air feed equipment is in slave mode all the time; Can not in time find when 2. air compressor breaks down, have the hidden danger that influences institute's sintered products quality.
Summary of the invention
In order to overcome above-mentioned defective, the utility model provides a kind of air compressor low pressure prevention emergency alarm, and this emergency alarm is installed simple, easy to operate, when compressed air pressure is lower than setting value, the device sound that gives the alarm can in time be found, can not impact institute's sintered products quality
The utility model for the technological scheme that solves its technical problem and adopt is: a kind of air compressor low pressure prevention emergency alarm, comprise pressure switch and alarm, described pressure switch is electrically connected a described alarm and a power supply by electric wire respectively, and the pressure-measuring head of described pressure switch is installed between the air outlet and reduction valve of air compressor by connecting tube.
As further improvement of the utility model, described power supply is the 220V power supply.
As further improvement of the utility model, described pressure switch is provided with a certain threshold pression value, and described alarm is provided with warning light, when air pressure is lower than described threshold pression value, and the pressure switch action, warning light is bright, and alarm sends alarm sound simultaneously.
The beneficial effects of the utility model are: this emergency alarm is by being provided with pressure switch on steam line, can control the variation in pressure of air feeder in real time, when gas pressure is lower than the lower limit of setting pressure, transfer signals to alarm by the pressure switch action; By the setting of alarm, the signal that receives can be sent actuation of an alarm and sound.By the setting of this device, can effectively reduce repeatedly the waste in man-hour of spot check, can realize real-time monitoring again, stabilized product quality, minimizing product loss are had remarkable effect.
Description of drawings
Fig. 1 is the utility model user mode structural representation.
In conjunction with the accompanying drawings, make the following instructions:
1---pressure switch 2---alarm
3---power supply 4---air compressor
41---air outlet 42---reduction valve
11---electric wire 12---connecting tube
Embodiment
In conjunction with the accompanying drawings; the utility model is elaborated; but protection domain of the present utility model is not limited to following embodiment, and promptly the simple equivalent of being done with the utility model claim and description in every case changes and modifies, and all still belongs within the utility model patent covering scope.
As shown in Figure 1, a kind of air compressor low pressure prevention emergency alarm, comprise pressure switch 1 and alarm 2, pressure switch is electrically connected an alarm 2 and a 220V power supply 3 by electric wire 11 respectively, and the pressure-measuring head of pressure switch is installed between the air outlet 41 and reduction valve 42 of air compressor 4 by connecting tube 12.
Starting air compressor reaches about 7kgf/cm3 air pressure.
Pressure setting knob on the pressure switch is adjusted setting, reach the pressure that to set and require (example: 2kgf/cm3).
Close air compressor, air pressure is reduced gradually, when air pressure drops to 2kgf/m3 when following, the warning light of alarm is bright, sends alarm sound simultaneously.
