The cooling water tank leaks. If water leaks, the surface color of the quenched product will be blue-gray, and there will be peeling on the surface in severe cases. The reason is that the cooling water tank of the mesh belt under the quenching furnace leaks water into the inner cavity of the mesh belt, and the water is gasified and then goes upward. Push it into the furnace hall to oxidize and decarburize the surface of the product. The remedy is to find the leak point and weld it firmly, or replace the cooling tank with a new one.XK7145A XH7145A XHS7145 CNC MILLING MACHINE From the surface color of the air leakage and decarburization products, it is slightly whiter than the normal color, unnatural, and has serious peeling phenomenon.

Electric push rods generally use two-stage transmission. There are mainly two types of primary transmission deceleration, one is to use worm gear for deceleration, and the other is for gear deceleration; most of the two-stage transmission uses screw nuts. Its working principle is briefly described as follows:HORIZONTAL MITRE BAND SAW MACHINE BS-150G The motor output shaft worm drives the worm wheel to rotate, which makes the screw connected in the worm wheel rotate, and the nut on the screw moves axially in the guide tube. When the required stroke is reached, the nut boss presses down the travel switch to cut off the power, and the motor stops. The positive and negative controls are the same.HORIZONTAL MITRE BAND SAW MACHINE BS-170G After the motor is decelerated by the gear, it drives a pair of screw nuts, and the nuts are connected to the push rod, so that the rotational motion of the motor becomes the linear motion of the push rod, and the forward and reverse rotation of the motor is used to complete the push rod action. Through mechanisms such as various levers, rockers or connecting rods, complex actions such as rotation and shaking can be completed.
