The function of oxygen respirator tester
The oxygen respirator tester can not only test positive pressure oxygen respirators, but also test negative pressure oxygen respirators and mixed gas respirators. Various technical performances, as well as testing the performance of components of various types of respirators.

How to use the oxygen respirator tester
The exhaust and inflation of the tester are provided by an air pump
, and the air enters the change valve directly from the conduit. The air flow direction is changed by changing the action of the valve to achieve inflation and pumping. ⊙ means pulling out, and the sign means pushing in.
When it is necessary to inflate the respirator
, put the change valve handle in the pull position of the symbol ⊙. When it is necessary to extract the gas from the respirator, put the change valve handle in the push position. When checking the positive and negative pressure of the respirator, when the water column liquid level of the water column meter moves to the design specified parameters, the power should be turned off first, and the air path should be closed immediately through the opening and closing valve. When the opening and closing valve handle is in the position of the symbol ⊙, the air The air path is opened, and the air path is closed when the symbol is pushed, that is, the flow and cutoff of the air flow in the air path are realized through the action of the opening and closing valve. When testing various parameters of the respirator, you should first open the thread plug at the water injection port, observe whether the liquid level of the water column meter is at zero, turn on the power, and connect the respirator to the tester with a connecting rubber tube.
To test the air tightness of the complete respirator, connect the mouthpiece of the respirator to the tester
Open the opening and closing valve, put the change valve handle in the pulled position, and press the power switch. The air pump starts to work. Pay attention to the changes in the water column level. When the liquid level rises above (water column), turn off the power and immediately close the on-off valve. Observe the falling speed of the water column level. It should not exceed (water column) per minute. qualified.
