Introduction of hour mechanical counter
HM counter is a design , belonging to type of electromagnetism structure. Its structure is novel, clever, accuracy, functional stability and credibility, life span long, environmental orientation widely.The price is low;usage convenience.
it is widely applicablefor standard industry to account , extensively applied for the engineering machine, generator, empty press machine, water pump , hoist, various type of autos etc.
Total amount of actual work time be charged with follow, keeping watch on an investigation of precise instrument equipments to maintain a period to provide science basis.
Mount alternate current, it then starts record a work for time. These timers are divided into the 120V 60 Hzs and 240V 50 Hzs, two kinds of series, in the middle of the usage ,Its walking speed be completely related with the frequency of alternate current and be the alternate current as 60 Hzs, records a word(namely the word once rotated a word) for an hour, be the alternate current as 50 Hzs, an hour.
The round also records a word and strictly speak that the error margin of alternate current frequency is of error margin, the standard provision counts the error margin of machine as add or subtract1%.The total amount record of this timer can reach to for 99999.99 hours.
The attention counts the electric voltage that machine outer shell marks clearly, while using and preventing from use wrong; if electric voltage does not match, then may cause not to work or damage spare part etc,even breaking down.
While use,as far as possible to avoid strength ground vibration and impact
