Hydraulic Pullers & Its Working Principle
Pullers are prevalent in every industry because it is easy to use, cost-effective, and labor-saving. In charge of extending the working life of hydraulic pullers, necessary overhaul and maintenance are required.
Removing shaft-mounted parts without using the proper puller is time-consuming, and it causes damage to the machine you are trying to maintain.
Smaller types of pullers are widely used by technicians, such as in automotive industries. Large hydraulic pullers are used throughout heavy sectors such as paper planting, shipbuilding, power generators, oil & gas, rail, mining, etc.
What are Hydraulic Pullers
Hydraulic pullers are used to remove shaft-fitting parts. Pullers effectively used hydraulic force to remove bearings and couplings. They usually have two or three jaws circled the back or inside. It also has a forcing screw that centers up against the end of a shaft.
Working Principle of Hydraulic Pullers
The hydraulic pullers drive straight forward with the hydraulic starting rod, so the push does not rotate. The hook seat can be adjusted with the thread ahead and backward. During the process, as long as the handle is slightly reeled back, the hydraulic starter rod moves forward, and the puller pulls out the object.
Features to be considered while selecting Hydraulic Pullers
Pullers are great tools for removing components in many industries. While choosing pullers for your business premises, these terms must be considered.
Two or Three Jaws
The most common type of puller is two-jaw and three-jaw pullers. Due to one extra jaw, three hydraulic jaw pullers are used in various industries because it divides loads evenly.
Hydraulic vs. Mechanical
Hydraulic pullers are more accessible than mechanical pullers but require a pump, hose, and gauge. A pump powered by air, electricity, or hand depends on the puller’s size.
Reach
Reach is the difference between the jaw’s pulling surface and the puller’s jaw head.
Spread
The spread is the diameter the jaws extend, usually up to 25 inches.
Synchronous and self-centering Jaws
The synchronized feature of pullers allows all jaws to move simultaneously. With the help of this feature, the spindle stays connected to shafts and takes less time to set up.
