iconProduct function

◆Touch screen human-machine interface automatic control, easy to operate, beautiful interface, precise control.

◆The interior of the working space is designed with stainless steel and no dead corners. The temperature and humidity field is uniform, the layout is reasonable, and it is convenient for the placement of the tested instruments, thus preventing the improper placement of the tested objects from affecting the calibration environment.

◆Two adjustment test holes are convenient for operation, and the inspector can insert both hands into the box to directly adjust the tested instrument inside the box. Since there is no need to open the door, there is no impact on the testing environment in the workshop during calibration.

◆Two or three observation windows are used for multi-directional observation and testing. Multi layer vacuum glass has good seismic and thermal insulation performance, and the size of the observation window is reasonable, making it convenient to pay attention to the testing process at all times.

◆Low heat cold light LED lighting display, observing the detection process from all angles without dead corners.

◆Humidity control system: Humidification is achieved by heating water to produce water vapor. Humidification is done as steam instead of water particles, which is more uniform. Dehumidification is achieved by condensing water with a refrigeration machine to achieve dehumidification, and the dehumidification speed is fast.

◆Temperature control system: Heating is done using stainless steel heating tubes, which provide uniform heating and fast speed; Cooling is achieved through the use of high quality compressors, with a well-designed control system and fast cooling speed.

◆Temperature and humidity control sensor: High quality temperature and humidity probe has high measurement range and accuracy.

◆Appearance: The design is aesthetically pleasing and elegant.

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.
