As a device designed for industrial applications, the pressure switch ST307-V2-150-B is suitable for use in the fire-resistant oil system of steam turbines to monitor and control the pressure in the hydraulic circuit. Specifically for its application in fire-resistant oil systems, the main responsibility of the ST307-V2-150-B pressure switch is to sense and respond to the moment when the preset pressure value is reached in the hydraulic circuit, so as to perform corresponding control actions, such as alarm or start/stop related equipment. The following are several key roles and considerations in the fire-resistant oil system of steam turbines:

Pressure monitoring: In the fire-resistant oil system, the ST307-V2-150-B can continuously monitor the pressure level of the hydraulic oil to ensure that the system operates within a safe and efficient pressure range. This is essential to prevent equipment damage or system failure caused by overpressure or underpressure.

Safety protection: When the pressure exceeds or falls below the set safety threshold, the pressure switch can quickly send a signal to the control system, triggering an emergency shutdown or other safety mechanism to prevent potential serious accidents, such as lubrication failure caused by insufficient oil pressure or seal damage caused by excessive oil pressure.

Accuracy and reliability: As a high-precision, high-reliability pressure switch, ST307-V2-150-B ensures measurement accuracy and reduces the possibility of false alarms or missed alarms, which is essential for maintaining continuous and stable operation of the turbine.

Adaptability and durability: Considering the working environment of the turbine fire-resistant oil system, ST307-V2-150-B is designed with attention to its long-term stable working ability in high temperature, vibration and oil erosion environments, which may include the use of corrosion-resistant materials, enhanced sealing structure and anti-vibration design.

Installation and maintenance: During installation, it is necessary to ensure that the interface between the pressure switch and the hydraulic circuit is well sealed to avoid leakage, and to facilitate regular inspection and calibration to maintain its accuracy and reliability.

Set point adjustment: According to the specific operating requirements of the turbine, the set point of the pressure switch can be adjusted to match different pressure control requirements, such as low oil pressure alarm, high oil pressure protection, etc.

In summary, the ST307-V2-150-B pressure switch plays an important role in pressure monitoring and safety protection in the steam turbine fire-resistant oil system, and its performance is directly related to the stability and safety of the entire system. Therefore, the correct selection, installation and maintenance of this type of pressure switch is the basis for ensuring the efficient and safe operation of the steam turbine.
