Product description

The pressure gauge calibrator, also known as a pressure gauge calibrator or a pressure gauge calibration pump, is based on the principle of increasing the pressure of the piston rod movement, thereby achieving the purpose of pressurization.

Installation

1. The calibrator should be placed on a workbench that is easy to operate and must be kept level.
2.The working environment temperature of the calibrator is+20 ± 10 ℃, and the surrounding air must not contain corrosive gases.
3. The calibrator shall not be subjected to vibration; Rubber pads need to be laid on the workbench.
4.Before use, first clean the calibrator pipeline with gasoline, and then fill the pressure medium into the oil cup. Rotate the hand wheel of the hand driven Screw pump to check whether the oil circuit is smooth; If there are no problems, precision pressure gauges and calibrated pressure gauges can be installed.

Operating steps

When inspecting the pressure gauge:
(1) Open the oil cup valve and turn the handwheel left to fill the cylinder of the hand pump with oil.
(2) Close the oil cup valve, open the valve, and then turn the handwheel to the right to compress the oil, so that the oil pressure acts on the pressure gauge. According to the indicated values of the two gauges, the inspection can be carried out.
When inspecting the vacuum gauge:
(1) Clear the internal pressure medium of the calibrator.
(2) Close the valve, open the oil cup valve, and screw all the screws of the hand pump into the cylinder.
