decay pressure gauge of the tilt steps:

tilt decline pressure gauge is a kind of measuring pressure gauge tube Angle can be changed. It is mainly composed of base, medium container, sounding pipe, arc support, zero regulators, multi-way valve, level, etc. With the foundation of the three adjustable level screw; Sounding pipe by colorless transparent glass control, on the length direction, even with more than 255 mm mm dividing cell; Sounding pipe can back and forth in arc shape bracket slot to adjust the Angle. Arc tilted bracket marked with a 5-speed constant k ( 0. 2, 0. 3, 0. 4, 0. 6, 0. 8) To measure a 5-speed range of gas pressure. Multi-way valve upside for 60 & deg; The rotary motion, top a + sign in black, & rarr; Symbol, mounted on the lower side label for 1, 2, 3, three mouth, according to the pressure measurement can be carried out on their particular combination. This tilt decay pressure gauge has characteristics, such as simple structure, good reliability, low price and popular.

( A) Preparation work

1) Open the packing cases cover, unscrew the packaging (on the bottom Fixed inclined weak pressure gauge) Two M10. 1 big screw, remove tilt decay pressure gauge, and then, on the base screw on 3 level screw ( Accessories) ;

2) Adjustable level: the decay of pressure gauge on flat workbench, slow adjustment under the base of three adjustment screw, the multi-way valve + alignment on no. 1 pick up nozzle. Make the level of air bubbles in the center position;

3) Deployment of medium density: anhydrous ethanol into a 500 ml measuring cylinder, and the full range of 800 ~ 900 ( Kg/m3 density meter into ethanol, and then, according to the need to add a little (distilled water At the same time will stir) Float the densimeter, observe when ethanol liquid level is a density meter to 810 ( Kg/m3) scribed line, which meet requirements;

4) Wash: ethanol mixed with good, from a liquid into the container, the container, measuring tube, nozzle to wash, and then poured out ethanol;

5) Zero: will tilt measuring tube under constant in 0. 8, zero regulator screw to near zui. Poured into the container again, alcohol to make ethanol reach the measuring tube near zero, cover good liquid cover. With one end of the rubber hose to the no. 1 pick up nozzle, the other end of the pressure source pressure ( Or blow) Rise to the top, making the measuring tube ethanol, repeated several times, until the measuring tube no bubbles and zero stable so far;

( 2) Pressure measurement

measured with inclined tube long strut opposite conical head screw in the measuring tube preset arc corresponding tilt on the constant of the support. For unknown gas pressure test, should choose tilt constant K = 0. 8 file, and then, according to the actual pressure to adjust K values. For different K value to zero.

delta positive pressure measurements: align on the multi-way valve + 1 mouth, measured with rubber and take 2 nozzle and pipe support upper nozzle connection, tested positive pressure joint connected with no. 1 pick up nozzle.

delta negative pressure measurements: keep positive pressure measurement of the position of multi-way valve and a rubber hose connected method, the joint of the measured negative pressure and no. 3 pick up nozzle connection.

delta differential pressure measurement: keep positive pressure measurement of the position of the multi-way valve and a rubber hose connected method, measured high pressure nozzle connection joint with the no. 1, low pressure joint to be tested and no. 3 pick up nozzle connection.
