(1) pump test before the tank with clean machine oil or vegetable oil, pressed the handle up and down to see whether the rising piston Oil processing. If the piston
Handle the pressure does not rise or move without effort, to check the tank valve, and the exclusion of the air pipe.
(2) for the whole pressure test, pressure test using 1.25 times the working pressure, check the piston out to the maximum working stroke, the regulator 15
Minutes, pressure gauge test pressure Food dehydrator must not exceed 4%; All oil should be no leakage; pressure drop in all, the gauge pointer back to "
0 "bit, the part should be no damage, trolley shall not have significant deformation, moving parts, no catching phenomenon.
(3) reliability test on the safety valve, safety valve adjusted to the working pressure (+5 upper left, lower left +1) MPa, continuous test five times, the needle valve opening and closing Ling
Min, each transition valve pressure gauge should not be less than the rated working pressure.
Before connecting the service line, fill cylinders with clean hydraulic fluid through the service ports. This reduces the danger of air compression within the cylinder on start up, which can lead to damage to the cylinder and its seals.
