Petrochemical PP Diaphragm Pressure Gauge Manufacturers

What are the advantages of the structural design of petrochemical PP diaphragm pressure gauge

Application of corrosion-resistant materials
Zhoushan Jiaerling Meter Co., Ltd. has a deep understanding of the impact of corrosive media on the performance of pressure gauges in its professional research in the petrochemical industry. To meet this challenge, Petrochemical PP Diaphragm Pressure Gauge uses polypropylene (PP) as the diaphragm material. Polypropylene has excellent corrosion resistance and can effectively resist the invasion of corrosive media such as various acids, alkalis and salts, thereby ensuring the long-term stable operation of the pressure gauge in harsh environments.
Precise structural design
The structural design of Petrochemical PP Diaphragm Pressure Gauge fully considers the specific needs of the petrochemical industry. The diaphragm part adopts high-precision processing technology to ensure uniform deformation when under pressure and accurate transmission of pressure signals. At the same time, the internal transmission mechanism is carefully designed to reduce friction and wear, and further improve the accuracy and stability of measurement. In addition, the pressure gauge also adopts an open connection flange design, which effectively avoids the deposition of viscous media in the pressure port and inside the pipeline, thereby ensuring accurate and reliable measurement results. This precise structural design not only improves the performance of the product, but also enhances its ability to adapt to various complex working conditions.
Easy to install and maintain
When designing the Petrochemical PP Diaphragm Pressure Gauge, Jiaerling fully considered the user's convenience needs. The pressure gauge has the characteristics of small size and compact structure, which enables it to be easily installed in places with limited space. In addition, the pressure gauge adopts standardized interfaces and modular design, which greatly facilitates the user's operation during replacement and maintenance. This humanized design concept not only improves the product's user experience, but also effectively reduces the user's maintenance time and cost.

How to do regular calibration of Petrochemical PP Diaphragm Pressure Gauge

Preparation before calibration
Configuration of calibration equipment
To ensure the accuracy of the calibration process, Jiaerling is equipped with a series of high-precision calibration equipment, including pressure calibration pumps, standard pressure gauges and a variety of adapters. The accuracy of these devices is higher than or equal to the accuracy requirements of the pressure gauge to be calibrated, thus providing a reliable basis for calibration.
Status inspection of the inspected pressure gauge
Before calibration, technicians need to conduct a comprehensive visual inspection of the Petrochemical PP Diaphragm Pressure Gauge. This step is to confirm the clarity of the dial, the flexibility of the pointer, and whether the various components are damaged or worn. At the same time, the identification information of the pressure gauge, including the manufacturer, model, range and accuracy level, needs to be verified to ensure the accuracy of all information.
Detailed description of calibration steps
Zero point calibration
The calibration equipment must first be set to zero pressure state, and the technician will observe whether the indication value of the Petrochemical PP Diaphragm Pressure Gauge accurately indicates zero. If a deviation is found, the technician will adjust the zero point of the pressure gauge to ensure that it is completely consistent with the zero pressure value of the calibration equipment.
Range calibration
During the range calibration stage, the calibration equipment will be set to multiple different pressure values. The technician needs to observe whether the indication value of the pressure gauge matches the set value. In order to avoid excessive impact on the pressure gauge, Jiaerling uses a slow and steady pressurization method for calibration. If there is a deviation, the technician will adjust the range of the pressure gauge to ensure the accuracy of its reading.
Linear calibration
Within the range range, the technician will select multiple pressure points for testing to verify whether the indication value of the pressure gauge shows a linear relationship with the pressure change. The indicated value of each pressure point will be recorded and compared with the set value of the calibration equipment. If nonlinearity is found, the technician will perform linear calibration to ensure the linear characteristics of the pressure gauge over the entire range.
Repeatability calibration
After completing the range calibration, the technician will perform multiple pressurization and decompression cycles on the Petrochemical PP Diaphragm Pressure Gauge to observe the changes in its indication. According to industry standards, the repeatability error should be less than 1/4 of the accuracy level of the pressure gauge being tested. This step is implemented to evaluate the stability and reliability of the pressure gauge during multiple pressurization and decompression processes.
Calibration record and identification management
After the calibration is completed, the technician needs to record the calibration results in detail in the calibration record sheet of the pressure gauge, including information such as the calibration date, operator, calibration equipment used, and final calibration results. In addition, a calibration qualified label or logo will be affixed to the calibrated pressure gauge for subsequent status identification and management. This process not only ensures the transparency of the calibration work, but also provides an important basis for subsequent maintenance and inspection.
