LYL-60 pressure gauge and oxygen gauge dual-purpose calibrator

1. Main purpose
This calibrator uses a manual plunger pump under the action of double levers to create pressure. The operation is light and labor-saving. The instrument itself is equipped with a secondary oil-water isolation setting. The structure is reasonably laid out, the performance is stable, safe and reliable, and it is suitable for measurement departments at all levels and It is an ideal and practical measuring equipment for factories, mines, enterprises and institutions to carry out calibration of pressure gauges, oxygen gauges and other oil-free pressure gauges.

3. Performance and technical indicators
. Working medium: clean instrument oil or transformer oil.
.Strength and sealing performance:
After the air is fully eliminated, the calibrator is pressurized to the test pressure specified in Table (1) for ten minutes to perform the strength and sealing test. Starting from the sixth minute, five The pressure drop value within minutes shall not be greater than that specified in Table (1).

.Working pressure sealing performance:
According to the test pressure specified in Table (2), pressurize step by step and stay at each level for one minute. The pressure drop value shall not exceed that level. % of load (excluding rebound value)

4. Structural Principle
This calibrator uses the oil-water separation method according to Pascal's principle to calibrate the oxygen meter and pressure gauge pipeline through a two-stage oil-water separation device. The oil pipeline and water pipeline transmit pressure. The joint of the calibrated oxygen meter in the water pipeline is specially used for calibrating oxygen meters and other oil-free pressure gauges. The joint in the oil pipeline is used to connect the standard pressure gauge and the calibrated pressure gauge.
