      傳感器在空壓機中起什么作用
      Time:2019-05-20 16:52:22       來源:http://www.592free.com/      

        傳感器作為一種檢測裝置,大多數儀器里都需要:上至登月的嫦娥四號,下至人手一部的手機電話,生活中幾乎已經離不開它了。當然在眾多行業機械中,傳感器也占了一席之地,包括我們行業熟知的空壓機,也需要傳感器。

        As a kind of detection device, sensors are needed in most instruments: Chang'e 4, which goes to the moon, and a mobile phone, which is almost indispensable in life. Of course, in many industry machinery, sensors also occupy a place, including air compressors, which are well known in our industry, also need sensors.
        那么,空氣壓縮機中傳感器起到了什么作用
        So, what role does the sensor play in the air compressor?
        在工作過中壓縮機實際所承擔的職責是提升壓力,將吸氣壓力狀態提高到排氣壓力狀態。壓縮比是壓力差的一種技術表示方式,其含義為高壓側絕對壓力除以低壓側的絕對壓力。壓縮比的計算必須采用絕對壓力值。為了避免使壓縮比計算值出現負值,計算壓力比時必須采用絕對壓力,而不是表壓力。采用絕對壓力值才能使壓縮比計算值為正值,這樣才有意義。
        In the course of working, the compressor actually assumes the responsibility of raising the pressure and raising the suction pressure state to the exhaust pressure state. Compression ratio is a technical expression of pressure difference, which means that the absolute pressure on the high side is divided by the absolute pressure on the low side. The absolute pressure must be used to calculate the compression ratio. In order to avoid negative compression ratio, absolute pressure, not gauge pressure, must be used to calculate pressure ratio. Only when absolute pressure is used can the compression ratio be positive, which makes sense.
        下面我們具體了解一下壓力傳感器在工業空氣壓縮機中的應用。
        Next, we have a detailed understanding of the pressure sensor in the industrial air compressor application.
        一般工業空氣壓縮機中的壓強大小為2hp到10000hp??諝鈮嚎s機主要用在氣動控制、執行、噴射設備,氣動工具,空氣排放操作等應用中。常見的空氣壓縮機一般工作壓強在125psi(約8.6個大氣壓),氣體流速大小為1CFM到15000CFM。當含有雜質或污染物的空氣經過壓縮機時,會極大的降低空氣壓縮機的工作效率,并減小其實用壽命。為此,一般生產制造商會通過加裝分離/過濾設備,以清除空氣中的贓物、水氣和油污。隨著過濾設備吸附污染物的增多,經過過濾后的氣體壓降會越來越大。因此,需要利用壓力傳感器對氣體的壓降進行監測。當氣體的壓降達到10psi時,壓力傳感器能夠觸發電路中的報警系統,以便通知操作人員及時清理或者更換過濾設備。由于氣體的壓降受到使用環境、過濾器使用時間長短、過濾的空氣量等多方面的因素影響。

        In general, the pressure in industrial air compressors ranges from 2 HP to 10 000 hp. Air compressor is mainly used in pneumatic control, execution, injection equipment, pneumatic tools, air emission operation and other applications. Common air compressors generally work at 125 psi (about 8.6 atmospheric pressure), and the gas flow rate is 1 CFM to 15 000 CFM. When air containing impurities or pollutants passes through the compressor, it will greatly reduce the working efficiency of the air compressor and its service life. To this end, manufacturers usually install separation/filtration equipment to remove stolen goods, water and oil in the air. With the increase of pollutants adsorbed by filtration equipment, the pressure drop of filtered gas will increase. Therefore, pressure sensor is needed to monitor the pressure drop of gas. When the pressure drop of the gas reaches 10psi, the pressure sensor can trigger the alarm system in the circuit to notify the operator to clean up or replace the filter equipment in time. Because the pressure drop of the gas is affected by many factors, such as the use environment, the length of time the filter is used, the amount of air filtered and so on.
        大量程的壓力傳感器,可以用于工業級的空氣壓縮機使用,并且幾乎可以連接任何的微控制器,通信協議簡單,無需對設備中的內部寄存器進行編程。凝膠保護和防磁不銹鋼帽可保護壓力芯片??梢詮V泛適用于智能手機,平板電腦,個人導航設備,胎壓計中。
        A large range of pressure sensors can be used in industrial air compressors, and can be connected to almost any microcontroller. The communication protocol is simple, and there is no need to program the internal registers in the equipment. Gel protection and diamagnetic stainless steel cap protect the pressure chip. It can be widely used in smartphones, tablets, personal navigation devices, tire pressure gauges.
