空壓機工作時意外停機的原因有哪些？

空壓機意外停機主要指因設備出現(xiàn)異常造成的臨時停用，并非正常的計劃停機檢修。為了提高生產(chǎn)效率和安全性，減少空壓機非預期停機時間是空壓機設備管理工作者努力的方向。通常情況下，空壓機非預期停機出現(xiàn)原因主要在以下幾個方面。

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常見的故障，其危害性。通常螺桿空壓機的工作溫度在65℃～85℃之間，設定**排氣溫度為100℃，超過此溫度時便會自動停機報警。如果設備長期處在高排氣溫度狀況下運行，過高的溫度會使轉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，甚至出現(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，當形變達到一定距離時，就推動連桿動作，使控制電路斷開，從而使接觸器失電，主電路斷開，實現(xiàn)電動機的過載保護。繼電器作為電動機的過載保護元件，以其體積小，結構簡單、成本低等優(yōu)點在生產(chǎn)中得到了廣泛應用。

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.
