DTH HAMMER application scope:
Widely utilized in metallurgical, coal, chemical, developing supplies are not busy mines and drinking water conservancy, hydropower, highway and railway defense building initiatives, etc. Appropriate for dry wind water mixing and shotgun-gap drinking water gushing moist operation, reliable performance, is the ideal drilling gap and rock drilling equipment.

DTH HAMMER software scope:
When the affect stroke starts, piston and disc are in the upper position, air stress passes by way of radial holes in the bonnet and seat into the higher chamber of the cylinder, thrust the piston down at substantial speed to influence the drill bit. When the piston goes to the spline keyway of the bushing is shut, Strain in the reduce cavity begins to increase, the heart gap at the prime of the piston leaves the valve rod, ventilate the higher chamber, drop in force stop of work journey. When the piston hits the finish of the bit, simply because of the upper and reduce pressure variation, the valve disc reverses and the piston returns to the stroke regularly.

two.Incorrect measurement or thread: New back for new.

three.Weak solder joints, broken wing pieces, and so on. : dress in not a lot more than twenty%, send again for a new CZPT r much more than fifty%, this sort of as synthetic incorrect operation, do not change.

4.The problem of lamination of composite slices: It is dependent.



TB 1610-25 Taper Bushings are common tapered bushings employed to lock pulleys, wheels, couplings and other components on push shafts. Bushings have tapered outer surfaces and cylindrical bores with H7 tolerances, such as common keyways. Once secured, the assembly is ready to transmit torque even though making sure that it is not impacted by axial displacement.
