Sanding machine hydraulic cylinder failure?

Sanding machine hydraulic cylinder failed to do: there are several common treatment, I will introduce you to: 1. Hydraulic system pressure is too low for sand control pipe resistance may be too large, improper flow valve adjustment, control of pressure is not appropriate, the pressure source interference. Check the pressure source, at this time to ensure that the pressure is set to the specified value. 2. Valve block sanding machine when the flow valve plug, the hydraulic cylinder are prone to misoperation or action failure, at this time should check the oil pollution. 3. Cylinder piston rod and cylinder when stuck sanding machine, no matter how to operate, the hydraulic cylinder action or action. At this point should be check piston and piston rod sealed tight, whether into the viscera and colloid sediments. 4. Hydraulic cylinder sanding machine in low temperature, low hydraulic oil viscosity, liquidity is poor under the condition of slow, lead to slow hydraulic cylinder. The solution is to replace with good viscosity-temperature function of hydraulic oil.
