Jiangsu Jinhu Huasheng Measuring Instrument Co., LtdThe 2022 May Day holiday schedule is as follows: from April 30th to May 4th, there will be 5 days of compensatory leave. I will be working on April 24th (Sunday) and May 7th (Saturday).

1. Overview

HS-YTD-6MBF Portable pneumatic pump(hereinafter referred to as calibration pump) is an important auxiliary equipment in pressure detection work, used in conjunction with pressure standards to complete pressure instrument calibration and detection work.

The lever drives the large capacity chamber piston to make reciprocating motion, generating pressure or vacuum. The pressure or vacuum is output through the switching switch, and then through the stabilizing valve to the fine-tuning and pressure output interface. Combined with intricately designed fine-tuning, quick interface, and stabilizing valve components. The advantages of simple operation, reasonable structure, and good sealing performance can be widely used in industries such as metrology, scientific research, industrial and mining enterprises, and instrument manufacturing.

3Usage and operation

3.1.pressure detection

③

Close the vent valve and unscrew the output1Output2The plug on the connector,

Connect the standard table and the inspected table, tighten the standard table and the inspected table. Adjust the fine-tuning to the appropriate position (middle position). Apply pressure to the operating lever0.5MPaThen, use fine-tuning to adjust it1.5MPa. Stable1~2Minutes, use fine-tuning to adjust to the calibration point1MPaDetect point by point until zero, (Be careful to apply pressure slowly, the pressure calibration table can reach a maximum of6MPa,To avoid overvoltage on the instrument.

3.2.Negative pressure detection

Pull out the toggle switch and unscrew the output1Output2Connect the plug on the connector to the standard gauge and the inspected gauge, adjust the fine adjustment to the appropriate position (middle position), and close the vent valve. Operate the lever to evacuate, when the pressure reaches-95kPaLeft and right. stable1~2Minute by minute, use fine-tuning to adjust to the calibration point and check point by point until zero.

(First, adjust the pressure to10.5MPaLeft and right, stabilizing voltage1~2After minutes, slowly adjust to10MPa)

4Precautions

4.16The calibration pump should be placed on a flat and easy to operate table, avoiding use in environments with highly corrosive gases and dust particles.

4.2The tested instrument should be cleaned appropriately to prevent stains from entering the detection circuit.
