Small make up teach you how to choose and micro pressure table

Micro pressure table ( Bellows pressure gauge) Is based on the working principle of moire bellows under pressure measured medium, its free end produce elastic deformation, then through a pull rod and amplification, transmission gear transmission mechanism by pointer fixed on gear shaft by measured values will be indicated on the dial out. Micro pressure table ( Bellows pressure gauge) Suitable for measuring the corrode the copper alloy, no explosion danger of micro pressure and negative pressure. Gas is widely used in boiler ventilation and gas pipeline equipment, such as bellows pressure gauge can be on-site installation and instructions on site. Micro pressure table part includes: measuring system ( Including joints, corrugated box, etc. ) And drive mechanism ( Including the pull rod, gear transmission mechanism) , indicating device ( Including the pointer and dial) And the shell ( Including watchcase, lining and table cover glass or PC) 。 Micro pressure table of choose and buy when should pay attention to: in the process of micro pressure table pointer should be smooth, no jump needle, stagnation phenomenon. Pressure gauge is not operation, limited check nails, nail should be close to the limit, and within the zero mark line. （ Visual) Micro pressure table visible parts have no obvious blemishes, scratch or damage. Pointer, installation method, pan, cover, inside the machine, joint and table cover shall comply with the requirements of customers to buy. Micro pressure table of joint thread must not collapse without grinding, bald and the phenomena of tooth; Table should maintain a transparent light, no oil, scratches. For electroplating parts, can not have product paint, such as orange stripes have obvious flaw phenomenon. Micro pressure table must be set the appropriate bubble bag or plastic bag, and put the corresponding outer.
