The hydraulic puller is automatically aligned to prevent eccentric load, ensure that the screw is always in the center of stress, and extend the service life. Then, the puller can be quickly controlled by the T-shaped handle and the safety cage, which is more convenient to operate. Especially now it does not have a screw design, and the plunger of the large stroke cylinder directly acts on the drawn workpiece, making the operation simpler and safer. When using hydraulic puller, pay attention to check the gear meshing and wear of all reducers. The pitting damage on the tooth surface shall not exceed 30% of the meshing surface, and the depth shall not exceed 10% of the original tooth thickness (fixed chord tooth thickness); The percentage of gear tooth thickness wear to the original tooth thickness shall not exceed 15%-25%; Check the bearing condition; Replace lubricating oil. Then check the condition of the large and small wheels, lubricate the wheel bearings, and eliminate the phenomenon of rail gnawing. It is then necessary to check the main welds of the hydraulic puller main beam and end beam for open welding and corrosion. Corrosion shall not exceed 10% of the original plate thickness, whether there are fatigue cracks in the main stressed parts; whether all kinds of guardrails and supports are complete; check and tighten the bolts of the main beam and end beam.
Attention should be paid to the gear meshing and wear of all reducers when using hydraulic pullers. The pitting damage on the tooth surface shall not exceed 30% of the meshing surface, and the depth shall not exceed 10% of the original tooth thickness (fixed chord tooth thickness); The percentage of gear tooth thickness wear to the original tooth thickness shall not exceed 15%-25%; Check the bearing condition; Replace lubricating oil. Check the condition of the rollers. The wear of the drum wall should not exceed 20% of the original wall thickness, and the convex peaks of the rope groove should not be sharp. Then, tighten all connecting bolts and fastening bolts immediately after the hydraulic pull. In short, this hydraulic puller is widely used in petroleum, chemical and other potential fire and explosion hazard environments. Hydraulic puller is also an indispensable special tool for machine manufacturing and machine maintenance. Therefore, it is now suitable for the inspection and maintenance of railway vehicles, mechanical installation, mine maintenance, removable pulleys, gears, bearings and other round workpieces in various mechanical equipment. Of course, our company's products can still meet these, and we are also welcome to establish long-term cooperative relations with friends from all over the country. After all, it is very famous in this industry, and the price is reasonable and the quality is guaranteed.
