有一种开关可以告诉我们压力大小，当达到压力值的时候可以为我们示警，还可以控制压力信号，没错，它就是压力开关。压力开关因为具有以上优越的性能被应用于石油、冶金、电力、供水等等的领域，因此，今天就了解下川消压力开关的安装维护和故障排除。

There is a switch that can tell us the pressure. When the pressure value is reached, it can warn us and control the pressure signal. Yes, it is a pressure switch. Pressure switches have been used in petroleum, metallurgy, electric power, water supply and other fields because of the above superior performance. Therefore, today we will learn about the installation, maintenance and troubleshooting of xiachuanxiao pressure switch.

一、压力开关安装问题详解

1、 Detailed explanation of pressure switch installation

1、要确定安装开关周围的环境温度，要求不能低于零下40摄氏度，不能高于零上70摄氏度，湿度不能高于85%，完成后仔细观察一下压力波动和振动，仪表是否可以正常工作。

1. To determine the ambient temperature around the installation switch, it is required that the temperature should not be lower than - 40 ° C, not higher than - 70 ° C, and the humidity should not be higher than 85%. After completion, carefully observe the pressure fluctuation and vibration to see if the instrument can work normally.

2、安装之前要仔细的核对接口的规格，以及型号，规格等等，以免后续出现问题无法正常安装。

2. Before installation, carefully check the specification, model, specification, etc. of the interface, so as to avoid subsequent problems and normal installation.

3、在安装和拆卸的过程中，要格外小心以免使得开关壳体与传感器的位置发生移动

3. During installation and removal, be careful not to move the switch housing and sensor

4、压力开关的安装，核心问题是能够反应出该点的被测压力，因此安装好之后需要多次检查。

4. The core problem in the installation of pressure switch is that it can reflect the measured pressure at this point. Therefore, it needs to be inspected several times after installation.

二、压力开关需要维护

2、 The pressure switch needs maintenance

1、在使用过程中，为了避免出现各种疑难杂症，需要定期检查开关是否有被腐蚀的现象，连接的整个过程是否有渗漏的可能。

1. In the process of use, in order to avoid various difficult problems, it is necessary to regularly check whether the switch is corroded and whether there is leakage in the whole process of connection.

2、开关指示是否有松动的迹象

2. Whether the switch indication is loose

3、电缆的进线是否密封完好，标识是否有破损的情况，保温状态是否良好等等。

3. Whether the incoming line of the cable is well sealed, whether the identification is damaged, whether the thermal insulation is in good condition, etc.

当使用中的压力开关出现故障问题之后，需要由人士卸压，进行排空操作之后才可拆卸，更换拆线的过程中需要断电，而且换上的开关容量不可低于额定值，修理好后需要反复调试，测试合格，正常运行之后才能正常使用。关注我们http://www.cx-fire.com，了解更多事项！

When the pressure switch in use has a fault, it needs to be relieved by a professional and can be disassembled after the emptying operation. During the process of replacement and disconnection, it needs to be powered off, and the capacity of the replaced switch cannot be lower than the rated value. After repair, it needs to be repeatedly debugged and tested to be qualified. It can be used normally after normal operation. Follow us http://www.cx-fire.com Yes, learn more!
