گThe pressure gauge in a manual hydraulic pump is a very important measuring instrument used to display the amount of pressure generated by the pump and transmitted to the hydraulic circuit. This component helps the operator ensure the system's safety and the proper functioning of the hydraulic tool.
Role and importance of a pressure gauge
- Monitoring the generated pressure: the operator can check the oil pressure at any moment and ensure it reaches the desired level.
- Protecting the equipment and system: if the pressure rises too much, it can damage the tools or hoses. The pressure gauge provides a warning before any failure occurs.
- Enhancing safety: it allows the user to keep the pressure within a safe range and prevents accidents caused by excessive pressure.
- Calibration and troubleshooting: if there is any leakage or pressure drop in the system, the pressure gauge serves as a key indicator for quickly identifying the problem.
Components of a pressure gauge
- Dial: the numerical display of pressure.
- Pointer: indicates the real-time pressure
- Threaded connection: used for mounting on a pump or hose.
- Protective casing: usually made of steel or stainless steel to withstand pressure and impact.
Pressure range in manual hydraulic pumps
- ChatGPT said: They are typically designed for a range of 0 to 700 bar (10,000 psi).
- The gauge should be selected according to the maximum working pressure of the pump and the connected tools.
Types of pressure gauges in hydraulic systems
- Dry pressure gauge: simple and economical, suitable for standard environments.
- Oil-filled pressure gauge: filled with silicone or glycerin to reduce needle vibration and increase accuracy.
- Digital pressure gauge: features a digital display with high accuracy, suitable for precise industrial applications.
Important points for use
- The gauge should always be installed near the pump outlet to accurately display the system pressure
- It should be protected from mechanical shocks and excessive vibrations
- The gauge range should be slightly higher than the pump’s working pressure (for example, for a 600-bar pump, a 700-bar gauge is selected).
- Periodic calibration is essential for measurement accuracy
