Debugging a universal testing machine

(1) Turn off the oil pump motor, turn off the MS wire on the oil pump, discharge the air in the pump (and a small amount of oil flows out), and then rotate the wire block: start the oil pump to lift and lower the piston repeatedly to drain the air in the oil cylinder and oil pipe. (2) Pull the cold bend support equally apart to both sides, which shall prevail if it does not touch the cross beam when lifting and lowering.

(1) turn off the oil pump motor, screw out the MS plug on the oil pump, discharge the air in the pump (with a small amount of oil outflow), exhaust air spinning waste blocking: start the pump lift cylinder piston will be repeated, the air exhaust pipe. (2) will be opened cold-formedsupport to both sides equally, to move the lifting does not meet standard

(3) Install spherical lower pressing plate on the platen, lift and move the cross beam so that the upper and lower pressing plates are about 20mm apart.

(3) mounted spherical plate under the bedplate, lifting and moving beam makes the upper and lower plates are about 20mm

(4) Start the oil pump, close the oil return valve and open the oil supply valve to make the platen rise, and slowly increase the pressure

(4) start the pump, close the valve to open the oil valve plate slow to rise, increasing pressure

(5) Check whether there is any oil leakage at each oil pipe joint (6) If there is oil leakage, tighten the oil joint after unloading the force

(5) check the tubing joints have no leakage (6) such as a leak, tighten the oil unloading forcejoint
