The intelligent pressure calibrator has been recognized by many instrument technicians for its advantages such as ease of use, stable performance, and intuitive readings. Intelligent pressure calibrators can be used for laboratory or on-site online testing and calibration of pressure transmitters, ordinary (precision) Bourdon tube pressure gauges, pressure controllers, and other pressure measuring instruments with a precision class of 0.05. They can also be utilized for calibrating pressure instruments in thermal engineering laboratories across various industries, such as pressure (differential pressure) transmitters, precision pressure gauges, general-purpose pressure gauges, pressure sensors, and pressure switches. Below are some brief introductions to the common faults of intelligent pressure calibrators and their solutions. I. Unstable hydraulic pressure or inability to generate pressure properly. Causes of faults in the intelligent pressure calibrator: 1. Insufficient oil level in the tank. 2. Damage to the pipeline joints occurred during transportation, resulting in leaks. 3. The sealing ring of the quick connector in “○” shape is damaged. 4. There is too much air in the system or it has not been fully exhausted. Processing method for intelligent pressure calibrator: 1. Loosen the fuel tank cap or fill the fuel tank. 2. Tighten the pipeline connections. 3. Replace the “○” ring. 4. Repeatally operate the oil filling pump to expel air in the system along with the oil. II. The negative pressure does not meet the standards. Causes of failure in the smart pressure calibrator: 1. The directional valve does not switch properly, resulting in air leakage. 2. The positive pressure check valve or negative pressure check valve fails to return to its original position after moving, resulting in air compression. Solution: 1. The directional valve must be switched to the correct position; the valve stem must not remain suspended in mid-air. 2. Check whether the seat holes of the positive pressure and negative pressure check valves meet the requirements; if they have not returned to their proper position, adjust them as soon as possible to restore that position.
