, and the insertion depth shall not exceed 10mm,
a. The thickness of the welding pad should be greater than 1.25 times the bolt diameter: bzxz.net
b. After the bolts are tightened, check with a 0.05mm feeler gauge, and the insertion depth shall not exceed 10mm
a. The thickness of the welding pad should be greater than 1.25 times the bolt diameter;
b. After the bolts are tightened, use a test hammer to check the tightening condition:
c. The contact between the mounting surfaces should be good.
After the bolts are tightened, check with a 0.05mm feeler gauge. The insertion depth should not exceed 10mm.
After the machine base is in place, no more than three steel sheets or pot skins are allowed to be used as gaskets between each support, but half a gasket is not allowed.
Note: 1) Generally refers to the machine with a motor power not exceeding 10kW and a machine base fixing bolt not exceeding M27. 3.4 Live gaskets may also be epoxy injection gaskets approved by the ship inspection department.
