Seismic pressure gauge is a pressure measuring instrument with seismic performance, widely used in industries such as petroleum, chemical, metallurgy, and power. In order to ensure the quality and performance of pressure gauges, China has formulated corresponding implementation standards. Below, we will discuss耐震压力表YNDetailed analysis of the execution standards.

　　

1、 Definition and classification of pressure gauge YN

　　

Pressure gauge YN refers to a pressure gauge that can work normally in harsh environments such as vibration and impact. According to its structure and function, pressure gauges YN are mainly divided into two categories: mechanical shock resistant pressure gauges and electronic shock resistant pressure gauges.

　　

2、 Main technical requirements for pressure gauge YN

　　

1. Accuracy level: The accuracy level of pressure gauge YN should comply with the national standard GB/T1226-2017 "General Pressure Gauge", where the accuracy level of mechanical shock resistant pressure gauge is 1.0 level and the accuracy level of electronic shock resistant pressure gauge is 0.5 level.

　　

2. Anti vibration performance: The pressure gauge YN should have good anti vibration performance and be able to work normally in harsh environments such as vibration and impact. Specifically, the anti vibration performance of mechanical shock resistant pressure gauges should comply with the national standard GB/T3166-2018 "General Pressure Gauge", and the anti vibration performance of electronic shock resistant pressure gauges should comply with the industry standard JB/T8249-1996 "Electronic Shock resistant Pressure Gauge".

　　

3. Environmental adaptability: The shock resistant pressure gauge YN should have good environmental adaptability and be able to work normally under changes in environmental factors such as temperature and humidity. Specifically, the environmental adaptability of mechanical shock resistant pressure gauges should comply with the national standard GB/T3166-2018 "General Pressure Gauge", and the environmental adaptability of electronic shock resistant pressure gauges should comply with the industry standard JB/T8249-1996 "Electronic Shock resistant Pressure Gauge".

　　

4. Electrical performance: The electrical performance of electronic shock resistant pressure gauges should comply with the industry standard JB/T8249-1996 "Electronic Shock resistant Pressure Gauge", including the stability of output signals, anti-interference ability, etc.

　　

3、 Testing method

　　

The inspection methods for pressure gauge YN mainly include visual inspection, accuracy inspection, anti vibration performance inspection, environmental adaptability inspection, and electrical performance inspection. The specific inspection methods and requirements should refer to the national standard GB/T1226-2017 "General Pressure Gauge" and the industry standard JB/T8249-1996 "Electronic Seismic Pressure Gauge".

　　

In order to ensure the normal operation and service life of the shock resistant pressure gauge YN, users should pay attention to the following points during use:

　　

1. Choose appropriate models and specifications to meet the requirements of actual working pressure and usage environment.

　　

2. Regularly conduct appearance and performance inspections, and promptly address any issues found.

　　

3. Avoid using in harsh environments such as high temperature, high humidity, and strong magnetic fields.

　　

4. Avoid severe vibrations and impacts to prevent damage to the instrument.
