In the process of using a metal band sawing machine horizontal band saw, have you ever encountered a situation where the saw frame could not rise or fall properly?
First, we need to check whether the contact switch is good, and then check whether the hydraulic tank of the metal band saw machine is short of oil; Check and adjust the relief valve of band saw machine to restore the working hydraulic pressure to normal; Check the solenoid valve and hydraulic line for oil leakage.
Sometimes, because air enters the oil cylinder of the saw machine, the hydraulic cylinder of the band saw machine is piston type, which will cause damage to the oil pump or fail to reach the normal hydraulic state after entering the air. This situation is also easy to solve. The operator of the band saw machine only needs to loosen the screw at the top of the cylinder of the saw machine, open the oil pump, press up and down to make the gas of the cylinder discharged and then tighten the screw. If there is no screw at the top of the oil cylinder of the band saw machine, open one of the oil return channel to make the oil pump work and discharge the gas.
