How to use Piston Ring Pliers?

Piston Ring Pliers is a tool specially used for disassembling and disassembling piston rings. When using piston ring disassembling tongs, the ring on the disassembling tongs is used to clamp the opening of the piston ring. The pliers handle slowly shrinks, and the ring card slowly opens the piston ring, so that the piston ring can be taken out of the piston ring groove or put into the ring groove. When using piston ring pliers to disassemble and disassemble the piston ring, the force must be even, to avoid breaking or damaging the piston ring with too much force, and to avoid injury to the hand.

The number of parts in a car body is simply endless, with many types. But who is more important? Internal combustion engines can be among them. However, the piston ring is a very important wearing part in the internal combustion engine. Among the various parts that make up the engine, the role of the piston ring is the most delicate. Even a well-designed piston ring can cause all kinds of improper use and maintenance. malfunction. Take a look at the precautions for disassembling and disassembling the piston ring.

As a Piston Ring Pliers Supplier, share the precautions for disassembling and disassembling piston rings

(1) Place the piston vertically on the work table, hold the piston ring opening with both fingers, press the index finger against the head of the piston, hold the piston ring with the middle finger, and slowly apply the thumb to both ends, wait for the piston ring When the inner diameter is slightly larger than the diameter of the piston head, it is loaded or unloaded in parallel. The material of the piston ring is alloy cast iron, which has low strength. Care must be taken when disassembling the piston ring to avoid breaking.

(2) In order to prevent the gas in the cylinder from leaking from the piston opening, the openings of the piston rings must be staggered and installed. For pistons with two piston rings, the openings of the first and second piston rings should be staggered by 180 °. For pistons with three piston rings, the openings of the piston rings are usually staggered by 120 °. Note that the port should not be placed in the direction of the piston pin.

(3) For pistons with piston ring positioning pins, the piston ring opening should be aligned with the positioning pins when installing the piston ring.

(4) When the piston with the piston ring installed is installed in the cylinder, a thin layer of lubricant shall be applied to the inner wall of the cylinder. In order to prevent the piston ring from being broken, it is best to use a piston ring clamp, and tighten the piston ring before putting it into the cylinder.
