空壓機(jī)工作時(shí)意外停機(jī)的原因有哪些？

空壓機(jī)意外停機(jī)主要指因設(shè)備出現(xiàn)異常造成的臨時(shí)停用，并非正常的計(jì)劃停機(jī)檢修。為了提高生產(chǎn)效率和性，減少空壓機(jī)非預(yù)期停機(jī)時(shí)間是空壓機(jī)設(shè)備管理工作者努力的方向。通常情況下，空壓機(jī)非預(yù)期停機(jī)出現(xiàn)原因主要在以下幾個(gè)方面。

The unexpected shutdown of air compressor mainly refers to the temporary shutdown caused by abnormal equipment, which is not the normal planned shutdown for maintenance. In order to improve production efficiency and safety, reducing the unexpected downtime of air compressor is the direction of air compressor equipment management workers. In general, the causes of unexpected shutdown of air compressor are mainly in the following aspects.

一、排氣溫度過高：高排氣溫度是螺桿空壓機(jī)常見的故障，其危害性。通常螺桿空壓機(jī)的工作溫度在65℃～85℃之間，設(shè)定**排氣溫度為100℃，超過此溫度時(shí)便會(huì)自動(dòng)停機(jī)報(bào)警。如果設(shè)備長(zhǎng)期處在高排氣溫度狀況下運(yùn)行，過高的溫度會(huì)使轉(zhuǎn)子和軸承材料的物理系數(shù)值產(chǎn)生變化，使軸承產(chǎn)生異常摩擦損耗，甚出現(xiàn)軸承散珠事故。

1、 High exhaust temperature: high exhaust temperature is a common fault of screw air compressor, its harmfulness. Generally, the working temperature of screw air compressor is between 65 ℃ and 85 ℃, and the * * exhaust temperature is set to 100 ℃. If the temperature exceeds this temperature, it will automatically stop and alarm. If the equipment is operated under the condition of high exhaust temperature for a long time, too high temperature will change the physical coefficient of rotor and bearing material, which will cause abnormal friction loss of bearing, and even cause bearing bead scattering accident.

二、熱繼電器跳開：熱繼電器的工作原理是由流入熱元件的電流產(chǎn)生熱量，使有不同膨脹系數(shù)的雙金屬片發(fā)生形變，當(dāng)形變達(dá)到一定距離時(shí)，就推動(dòng)連桿動(dòng)作，使控制電路斷開，從而使接觸器失電，主電路斷開，實(shí)現(xiàn)電動(dòng)機(jī)的過載保護(hù)。繼電器作為電動(dòng)機(jī)的過載保護(hù)元件，以其體積小，結(jié)構(gòu)簡(jiǎn)單、成本低等優(yōu)點(diǎn)在生產(chǎn)中得到了廣泛應(yīng)用。

2、 Thermal relay tripping: the working principle of the thermal relay is that the current flowing into the thermal element generates heat, which makes the bimetallic sheet with different expansion coefficient deform. When the deformation reaches a certain distance, the connecting rod will be pushed to open the control circuit, so that the contactor will lose power and the main circuit will be disconnected to realize the overload protection of the motor. As an overload protection component of motor, relay has been widely used in production because of its small size, simple structure and low cost.
