Journey.
The air inlet pipe that should be first connected between source of the gas and gas switching valve before deviation correcting device debugging, source of the gas is opened, and regulation subtracts
Pressure valve makes gas pressure in 0.4MP or so.Operation vacuum belt machine, starts debugging.When finding out filter cloth and running to centre position, pendulum
The location of arm, now two air bags（, first regulation air bag, second regulation air bag）Gas this position should be determined as much
It is equilbrium position.When the right sideslip of filter cloth or left sideslip reach maximum position, an air bag gassy, another air bag does not have
Gas, this position is maximum left correction position or maximum right correction position.Two steam vent air inflows of gas switching valve and exhaust
Amount is simultaneously and equal, drawn according to spot debugging experience, if in swing arm swing process, two steam vents enter gas output not
Together, air bag stroke can be caused not in place or side air bag is upturned, it is impossible to normal correction.
This correction mode process control procedure is simple, and trouble point is few.Air bag air inflow is no longer all-in and all-out, but root
According to correction swung the angular dimension coming year determine air bag air inlet number, make air bag fine motion make, improve the use of air bag
Life-span.Filter cloth substantially remains in the centre position of carrying roller when vacuum belt machine runs, by after one section of run time, without new pleating
With running pulp phenomenon, work of carrying out production strictly in line with rules and regulations greatly improves.Because filter cloth is without pleating phenomenon, the service life of filter cloth is extended.
