One, detailed description

Negative pressure oil samplerPrecision oil sample analysis, at the time of sampling should be especially careful to prevent dust and impurities and the previous sampling of residual oil mixed with oil.

Negative pressure oil samplerIncludes a negative pressure pumping oil and one-time use of pollution-free hose with an oil bottle (100ml, 250ml, 500ml, optional specifications), can effectively prevent oil adhesion oil grab and external contamination of the oil sample.

Two, the use of methods

The 1 round nut loosen around the hose through the nut, then tighten the nut and the fixed joint oil gun and hose. (lower hose out oil gun joint 1cm, in order to avoid oil gun joints and oil gun inside oil pollution)

2 the oil sample bottle is screwed to the oil gun joint. (while the oil temperature high oil extraction, such as at the end of the job after sampling. Each sampling condition should be the same)

3. If the tank is equipped with oil dipstick that can be pumped out, the hose into the oil, if the tank is equipped with oil level screw thiamethoxam, screw down, then the hose into the oil. (general, oil hose into the depth of about 50mm. In this way, the hose is not sucked into any sediment; because the hose is coiled stored, if the original use will reach the surface oil, then can in before straightening to required length; if the hose is too long, cut into the appropriate length, to ensure that the reduced oil resistance and smooth sucker)

4. Oil gun handle is pushed to the bottom, then with rubber sleeve cover the gun body at the front end of the holes, the gun handle is pulled back at the same time, the bottles will be forming a vacuum, so that the oil down the hose into the bottle. (if the above operation, oil gun a trip, smoke less than the required amount of oil, to loosen the cover rubber sleeve Tim refers to, towards the former massage gun handle, then repeat pumping oil operation)

5 of the oil pump to the 80ml marking on the bottle, do not make clear smoke filled with oil.

6 from the oil gun joint unscrew the bottle, mounted on the cover, be careful not to mix dust, impurities (outside. Then tighten the cover cap to screw tight).

At the end of 7, with a clean cloth or paper towel hose end. Unscrew the round nut, and the hose is drawn from the nut. (after each sucker, should be replaced with a new hose)
