空压机工作时意外停机的原因有哪些？

空压机意外停机主要指因设备出现异常造成的临时停用，并非正常的计划停机检修。为了提高生产效率和安全性，减少空压机非预期停机时间是空压机设备管理工作者努力的方向。通常情况下，空压机非预期停机出现原因主要在以下几个方面。

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、排气温度过高：高排气温度是螺杆空压机常见的故障，其危害性。通常螺杆空压机的工作温度在65℃～85℃之间，设定**排气温度为100℃，超过此温度时便会自动停机报警。如果设备长期处在高排气温度状况下运行，过高的温度会使转子和轴承材料的物理系数值产生变化，使轴承产生异常摩擦损耗，甚至出现轴承散珠事故。

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、热继电器跳开：热继电器的工作原理是由流入热元件的电流产生热量，使有不同膨胀系数的双金属片发生形变，当形变达到一定距离时，就推动连杆动作，使控制电路断开，从而使接触器失电，主电路断开，实现电动机的过载保护。继电器作为电动机的过载保护元件，以其体积小，结构简单、成本低等优点在生产中得到了广泛应用。

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.
