Handheld pressure pumpDivided into pneumatic pressure source and hydraulic pressure source. Usually used in conjunction with pressure calibrators or precision digital pressure gauges without pressure sources, it provides a stable and reliable pressure source when calibrating pressure instruments such as pressure gauges, pressure transmitters, and pressure switches. Handheld pressure pumps can also be used in conjunction with general pressure gauges for on-site debugging and pressure testing in pressure process control.
1 YFQ-025SHandheld pressure pumpTechnical Indicators:
1. Pressure range: (-0.088~1.6) MPa;
(-0.088～2.5)MPa。
2. Operating temperature: -20~50 ℃;
3. Weight: 0.6kg;
4. Pressure medium: It is a clean and non corrosive gas;
Product Features:
1. Hand clamp type compression, fast pressure rise;
2. Imported sealing components with good pressure holding effect;
3. Stainless steel components have a long service life.
Usage operation:
The top pressure output is connected to the standard table. If the interface is inconsistent, please specify the interface specifications when ordering to facilitate the matching of the adapter. The pressure outlet on the side is equipped with a medium pressure hose and connector as standard when leaving the factory. The connector specification is M20 × 1.5 (please specify when ordering other specifications), which is connected to the calibrated meter. Tighten the vent valve, use pliers to apply pressure to the desired value, and use a standard gauge as a reference to check if the pressure value on the calibrated gauge is consistent with the standard gauge. Adjust the calibrated gauge using a comparison method.


II YFQ-2.5SHandheld pressure pumpTechnical Indicators:
1. Pressure range: -95~250kPa, -95kPa~1.0MPa;
2. Operating temperature: -20~50 ℃;
3. Dimensions: 70 × 70 × 200mm;
4. Weight: 0.6kg;
5. Measurement medium: It is a clean and non corrosive gas.
Product Features:
1. The pump type push and pull pressurization is convenient to use;
2. Imported sealing components with good pressure holding effect;
3. Stainless steel components have a long service life;
4. Small size and easy to carry.
Usage operation:
The pressure output on both sides is equipped with hose connectors as standard at the factory, and the standard interface specification is M20 × 1.5 internal thread. One side is connected to the standard meter, and the other side is connected to the calibrated meter. Push or pull out the directional valve for positive and negative pressure to switch to positive pressure or shaft vacuum, close the vent valve, and continuously extract and push the pressure pump to increase the pressure to the desired value. Adjust the calibrated gauge by checking if the pressure value matches the standard gauge, and calibrate it using a comparative method.
III YFY-25Handheld pressure pumpTechnical Indicators:
1. Pressure range: (0-25) MPa;
2. Operating temperature: -20~50 ℃;
3. Weight: 0.8kg;
4. Voltage transmission medium: transformer oil.
Product Features:
1. Hand clamp type compression, fast pressure rise;
2. Imported sealing components with good pressure holding effect;
3. Stainless steel components have a long service life.
Usage operation:
The top pressure output is connected to the standard table. If the interface is inconsistent, please specify the interface specifications when ordering to facilitate the matching of the adapter. The pressure outlet on the side is equipped with a medium pressure hose and connector as standard when leaving the factory. The connector specification is M20 × 1.5 (please specify when ordering other specifications), which is connected to the calibrated meter. Inject 2/3 of transformer oil into the oil cup, tighten the oil drain valve, and use pliers to pressurize to the required pressure value. Use a standard gauge as a reference to check if the pressure value on the calibrated gauge is consistent with the standard gauge, and adjust the calibrated gauge using a comparison method.
