In the shipbuilding industry, the pressure calibration pump is a crucial device for ensuring the safe navigation and efficient operation of ships. The power system of a ship, such as the fuel injection pressure, lubricating oil pressure, and cooling system pressure of a diesel engine, requires precise control and calibration. The pressure calibration pump can calibrate the relevant pressure sensors and instruments, ensuring the stable operation of the engine under various working conditions and avoiding engine failures due to abnormal pressure, which could affect the ship's navigation. The hydraulic system of a ship is used to operate important equipment such as steering gears, windlasses, and cranes, and the accuracy of its pressure is directly related to the ship's handling performance and operational safety. The pressure calibration pump can provide accurate calibration for the pressure components of the hydraulic system, ensuring that the hydraulic oil transmits power at the appropriate pressure, making the ship's operations such as steering, berthing, and cargo handling precise and reliable. In addition, the ballast water system, fire protection system, and domestic water supply system of a ship also rely on the pressure calibration pump to calibrate pressure equipment, maintaining the normal operation of the systems and ensuring the overall safety, comfort, and functionality of the ship.
