Product Description
Pressure measuring medium: clean air (clean and non corrosive gas)
Operating temperature: 0-50 ºC
External size: 300×210×175(long × wide × High)
Instrument weight: 3.44kg
Pressure range: -0.095 ~ 0.6/0.8/1 MPa
Notes:
1. The calibration bench should be used within the rated pressure range as much as possible, and overpressure greater than the maximum range of 2MPa is prohibited.
2. The calibration table should be placed on a stable operating platform to avoid entering corrosive gases and dust particles used in the environment.
3. When switching between pressure and vacuum, it must be carried out in a state of no pressure.
4. Use a lever to apply pressure (pressure handle ), with even application force;
5. All handles and joints must not be operated with excessive force;
6. After prolonged use, apply an appropriate amount of lubricating grease to the threaded part.
7. Long-term storage should be in a dry, non-corrosive gas, and sun-proof environment.
Steps:
1. Connect the standard meter to the [Standard Meter Interface] and the calibrated instrument to the [Pressure Test Interface] ; (Keep the calibrated instrument clean and tidy)
2. Rotate counterclockwise to open pressure relief valve ; When verifying negative pressure, push the pressure/vacuum conversion valve forward; When verifying positive pressure, pull out the pressure/vacuum conversion valve ; (Positive pressure pump without pressure/vacuum switching valve)
3. Rotate Fine adjustment handwheel (positive pressure) counterclockwise and (negative pressure) to one-third of the position;
4. Rotate clockwise to close pressure relief valve ;
5. Hold the Pressure handle and repeatedly lift and lower the pressure (vacuum) to the desired value. When the pressure is high and the handle is difficult to press down, the lifting height can be reduced before pressing down. When the pressure reaches around 3MPa, it can be increased to 6MPa by adjusting the handwheel
6. Accurately adjust to the desired value through Fine adjustment handwheel ;(Positive pressure) Rotate clockwise to increase pressure, (vacuum) Rotate clockwise to decrease vacuum
7. Return calibration, slowly open the pressure relief valve to the desired value, and adjust the handwheel precisely to the desired value through fine adjustment; After the calibration is completed, rotate counterclockwise to open the pressure relief valve to relieve the pressure, and remove the calibrated gauge to complete this calibration Verification.
| No. | Name | Function |
| 1 | Pressure/vacuum switching valve | Spin in is vacuum, spin out is pressure |
| 2 | Pressure handle | Upward lifting and downward pressing |
| 3 | Boost fine adjustment handwheel | Boosting/precise adjustment of applied pressure |
| 4 | Standard Table Interface | Used to connect standard pressure gauges (thread size M20 × 1.5) |
| 5 | Pressure testing interface | Connect the calibrated pressure instrument interface (thread specification M20 × 1.5) |
| 6 | Pressure relief valve knob | Loosen and release the pressure inside the pump. Before generating pressure, tighten the knob and close the valve tightly |
Problems & Soulutions:
| Phenomenon | Reason | Method |
| Do not apply pressure when applying pressure to the handle | 1. The pressure relief valve knob is not tightened 2. The sealing ring in the quick connector falls off 3. The switching valve did not rotate properly 4. Inhalation of foreign objects in the gas path |
1. Tighten the pressure relief valve 2. Reinstall or replace with a new sealing ring 3. Push and pull the switching valve into place 4. Multiple pressurizations and rapid pressure relief |
| Slight leakage | 1. The quick interface is not ightened 2. The sealing ring is worn or aged 3. The pressure relief valve knob is not tightened |
1. Tighten all threaded joints 2. Replace the sealing ring with a new one 3. Tighten the pressure relief valve |
