The hydraulic puller starts the rod to move directly forward with oil pressure, so the push rod itself will not rotate. The hook and claw seat can directly adjust the front and rear distance from the thread. During the operation, as long as the handle swings back and forth slightly, the oil pressure start rod will move forward, the hook and claw will retreat accordingly, and the pulled object will be pulled out. The new hydraulic puller is simple to operate and labor-saving. The three-claw type and the two-claw type can be replaced according to the needs of on-site work. It can rotate freely and press the distance between the puller and the center point of the piston, and it can quickly contact the center point of the pulled workpiece. Optional pump. Today, let's understand the basics of it:
1. principle
It moves directly forward with the hydraulic starter rod, so the push rod itself will not rotate the hook, and the claw seat can also follow the screw. During operation, as long as the handle swings back and forth gently, the oil pressure starting rod will move forward, and the hook claw will retreat accordingly, pulling out the pulled object when space permits, which is convenient, fast and simple. It is an ideal new tool to replace the traditional puller. It is simple to operate, labor-saving, and is not limited by the site. The Lamar is compact in structure, flexible in use, light in weight, small in size and easy to carry. Suitable for factory and maintenance site.
2. Category
Hydraulic puller is divided into: integrated hydraulic puller, separate hydraulic puller, special puller for coupling, mobile hydraulic puller, separate anti-skid hydraulic puller and vehicle-mounted hydraulic puller.
3. Function Description
1. The new hydraulic puller is easy to operate and labor-saving.
2. Three claws and two claws can be replaced according to the needs of on-site work.
3. Optional pump.
4, flexible use, light weight, small size, easy to carry, is an ideal tool for factories, ships and maintenance sites.
4. method of use
It is an ideal new tool to replace the traditional puller. It has the characteristics of compact structure, flexible use, convenient and labor-saving operation, and less site restrictions, and is suitable for various maintenance sites.
1. Tighten the oil return valve stem clockwise before use.
2. Adjust the claw seat to the claw and grasp the pulled object.
3. Lift the piston starting rod back and forth, move forward smoothly, the claw hook retreats accordingly, and pull out the object to be pulled.
4. During use, if the extension distance of the piston start rod is required to be greater than the effective distance of the hydraulic pull-up piston start rod, when the extension distance reaches the effective distance, stop, loosen the oil return valve stem, and let the piston start rod Retract, repeat the steps 1-3 times after adjustment until it is pulled out; to loosen the oil return valve stem, just slightly release the oil return valve counterclockwise. The piston actuating rod is gradually retracted under the action of the spring.
5. Before use, the force required to pull the object must be estimated and the appropriate puller must be selected. Do not use overweight to avoid damage.
6. Its working oil should use anti-wear hydraulic oil, and the working oil must be clean.
5. considerations
Analysis of common problems of traditional hollow cylinder with screw hydraulic pular:
1. The jaw slips during operation, causing a safety accident.
2. The eccentric load puller causes the screw to bend and get stuck in the hollow cylinder, which is a dilemma.
3. The puller is subjected to eccentric load, causing the screw and jaw to break or straighten, causing safety accidents.
4. The cylinder stroke is too short and requires multiple positioning to complete the work, increasing the workload for no reason.
