Does mechanical wear of the gas gauge components affect measurement accuracy? - Digital display gas Momentum meter - Elaired Electromechanical Technology (Suzhou)

──Nov 09 , 2023Does mechanical wear of the gas gauge components affect measurement accuracy?

The mechanical wear of the components of the gas gauge will affect the change of the measurement magnification and the stability of the indication value, mainly4In this case:
(1) Magnification nail0When air leakage is caused by ring wear, the measurement ratio decreases.
(2Uneven wear and depression of the end face of the thimble cause the indication value to be unstable;
(3The measuring head wear causes the magnification to decrease;
(4The locking nut and the magnification nail have axial movement or radial swing, resulting in instability of the indicating value.

Adjustment method:

(1) Magnification nailOThe ring is worn and needs to be replacedOType rubber ring;

(2The end face of the thimble is worn and dented. Grind on the grinding plate with chromium oxide, and check that its flatness does not exceed with a knife edge square0.002μm;

(3The measuring head wear causes the magnification to decrease, and the measuring head should be replaced;

(4The locking nut and the magnification nail are adjusted to the appropriate position to achieve no obvious movement and swing. If after the lock nut is adjusted, the ratio nail is tight and loose, it indicates that the ratio nail part is worn and availableW5Chromium oxide, lock nut and rate nail mutual research, grinding finished, to nut and rate nailcheWash the bottom with detergent gasoline. When the equipment is equipped, the nuts and magnification nails should be refueled, and then the nuts and magnification nails should be adjusted to the appropriate elastic position, so that there is no obvious movement and swing.

As a precision parts size pneumatic measurement equipment manufacturers, focusing on micro-precision, R & D and production of digital display pneumatic momentum meter, a variety of models, quality assurance, manufacturers direct sales, price concessions.
