Desktop pressure calibratorIt is an integrated pressure calibration device with pressure control fine-tuning and pressure output functions. In order to help you quickly and correctly master the usage of this series of products, this user manual provides a detailed introduction to the technical specifications, instrument composition, operation, and precautions of this series of products. Please read the user manual carefully before use to ensure the reliability and stability of this series of instruments.
Overview
Desktop pressure calibrator(hereinafter referred to as pressure source) is an important auxiliary equipment in pressure instrument detection work, used in conjunction with pressure standards to complete pressure instrument calibration and detection work.
The pressure pump of the pressure calibrator uses a high-quality hydraulic pump as the pressure generating component, supplemented by well-designed fine-tuning, quick interface, and stabilizing valve components. The advantages of simple operation, reasonable structure, and good sealing performance make it a wide range pressure generating system that can be widely used in industries such as metrology, scientific research, industrial and mining enterprises, and instrument manufacturing.
2. Technical specifications: Pressure range: 0~100MPa, 0~60MPa, 0~40MPa, 0~25MPa, 0~10MPa, 0~6MPa, 0~2.5MPa. For more pressure ranges, please contact customer service
2.2 Sensitivity adjustment: min 10 Pa
2.3 Dimensions: 400 × 360 × 160 (length × width × height)
2.4 Weight: 9kg
2.5 Medium: Pure water or 20 # transformer oil
Usage and Operation
3.1. Forward detection
Unscrew the plugs on the connectors of output 1 and output 2, and adjust the micro adjustment to the appropriate position (middle position). Open the overpressure cut-off valve, cut-off valve, and pressure stabilizing valve on the water cup. Use force to operate the lever until there are no bubbles in the water cup. Close the cut-off valve and pressure stabilizing valve on the water cup. Gently operate the lever to direct the pressure liquid (or water) to the two pressure output ports. Reinstall the standard meter and the verified meter, operate the lever to increase the pressure to around the verification point, use fine-tuning to adjust to the verification point, and test point by point until the full range is reached. After verification, open the stabilizing valve, shut-off valve, and overpressure shut-off valve on the water cup in sequence.
3.2. Return Inspection
According to the regulations, after two readings at full range, slowly reduce the voltage to the calibration point with a fine adjustment, and test point by point until zero. When the adjustment cannot reduce the pressure, you can gently open the relief valve to reduce the pressure.
3.3. When the pressure drops slowly under high pressure, close the stabilizing valve. (For example, for a calibration bench with 0-100MPA, first use fine-tuning to adjust the pressure to around 105MPa, stabilize it for 1-3 minutes, and then slowly adjust it to 100MPa)
Precautions for Multi Interface Pressure Calibration Platform
4.1 The pressure pump should be placed on a flat and easy to operate table, avoiding use in environments with highly corrosive gases and dust particles.
4.2 The tested instrument should be properly cleaned to prevent stains from entering the detection circuit.
4.3 The output 1 and output 2 connectors are specialized quick connectors with sealed end faces. When installing the instrument, no tools are needed, and they should be tightened evenly. When the sealing surfaces are tightly attached to each other, they can be tightened 1-2 turns.
4.4 The output 1 and output 2 connectors are composed of upper and lower parts. When using, it is necessary to regularly check whether the lower locking screw is connected reliably. If the connection is not reliable, it may cause breakage under high pressure.
When the pressure generated by the lever is heavy, please use a fine adjustment to increase the pressure, which will be easier.
