Frequentlyquestions

The verification process can perform data analysis, calculation and automatic identification of excess errors;

Is the hydraulic pressure of the pressure pump unstable or unable to generate pressure normally?
Reasons: 1. Insufficient fuel level in the fuel tank; 2. Damage and leakage at the pipeline joints during transportation; 3. The sealing of the "○" ring of the quick connector is damaged; 4. The air in the system is too much or not completely discharged. Methods of solution: 1. Loosen the fuel tank cap or refuel the fuel tank; 2. Tighten the pipeline joints; 3. Replace the "○" ring (diameter 9 * 2.65); 4. Repeatedly pumping the charging pump allows the air in the system to be discharged with the fuel tank.
The common reasons for unstable hydraulic pressure or inability to generate pressure normally.
1. Insufficient fuel level in the fuel tank; 2. Damage and leakage at the pipeline joints during transportation; 3. Quick connector "○" ring seal damaged; 4. Too much or uncleaned air in the system.
What are the common reasons for empty pressure of pressure pump of manual pressure calibrator?
Reasons: 1. The directional valve does not change direction properly, resulting in air leakage; 2. The positive pressure check valve or negative pressure check valve does not reset after movement, resulting in air pressure phenomenon. Methods of solution: 1. The reversing valve must be reversed in place, and the reversing valve stem cannot be suspended in mid air; 2. Check if the one-way valve seat holes for positive and negative pressure do not meet the requirements; 3. The spring is severely tilted, and the one-way valve core cannot slide freely.
What are the specific advantages of Yuanhuatc's fully automatic pressure calibrator?
Yuanhuatc has high flexibility and adopts advanced analysis algorithms and automatic control technology, which can quickly and accurately complete verification tasks.
