General Definition of Excavator Breaker<\/h3>\n

Hydraulic Breaker<\/strong> is one of the most vital excavator attachments that is used to destroy and break hard materials such as concrete, stone, asphalt, and even resistant rocks in mines. This powerful equipment, using hydraulic oil pressure and nitrogen gas, produces a strong impact force and transfers it to the target surface through successive strokes of the pen.
\nIn order to increase the useful life and optimal performance of this device, the use of high-quality Hydraulic Breaker Parts<\/strong> is of particular importance. Kavir Machine Espadana Company<\/strong> is considered one of the most reliable and trustworthy suppliers in the country’s road construction and mining machinery market by providing various Hyundai Overtime Breaker parts and specialized services in this field.<\/p>\n

                What is a Picor Excavator Seal Kit?<\/h4>\n

                A Seal Kit is a set of washers, O-rings, packings, lip seals, dust traps, and gaskets that seal the hydraulic system and prevent oil leakage and contamination.<\/p>\n

                The main purpose of the seal kit:<\/h3>\n
                  \n
                1. Preventing hydraulic oil leakage<\/li>\n
                2. Maintaining hydraulic pressure inside the cylinder<\/li>\n
                3. Preventing dust or water from entering the internal components<\/li>\n
                4. Reducing friction between moving parts<\/li>\n
                5. Increasing the useful life of the piston and main components such as the piston, bushing and valve<\/li>\n<\/ol>\n

                  Symptoms of seal kit failure:<\/h3>\n
                    \n
                  1. Oil leakage from the piston body or next to the piston<\/li>\n
                  2. Reducing impact strength<\/li>\n
                  3. Oil leaking from the hoses despite tight connections<\/li>\n
                  4. Abnormal body heat<\/li>\n
                  5. The presence of foam or bubbles in the oil (sign of air entry)<\/li>\n<\/ol>\n

                    \"Seal<\/h3>\n

                    Recommendation when replacing the seal kit:<\/h3>\n

                    The parts must be completely clean, dry and free of burrs.<\/p>\n

                    Use a special sealing tool.<\/p>\n

                    Fully lubricate the O-rings before installation (with the machine’s own hydraulic oil).<\/p>\n

                    Use the original seal kit suitable for the Pikor model.<\/p>\n

                    Sometimes the accumulator gas pressure must be readjusted after installing the seal kit.<\/p>\n

                      \n

                            \"Hydraulic<\/p>\n

                            A diaphragm or “diaphragm rubber” is a flexible piece of reinforced rubber (usually with special fibers) that is installed at the top of a hydraulic hammer. The main function of the diaphragm gasket is to separate the nitrogen gas in the upper chamber of the hammer from the hydraulic oil.<\/p>\n

                            Excavator Picker Parts Working Cycle:<\/h3>\n
                              \n
                            1. Hydraulic oil enters the picker from the excavator pump and is directed to the back of the piston.<\/li>\n
                            2. The piston is pushed forward by oil pressure and hits the back of the pen at high speed.<\/li>\n
                            3. The pen hits a hard surface (concrete or stone) and crushes it.<\/li>\n
                            4. The oil drained from the front of the piston returns to the tank.<\/li>\n
                            5. This process is repeated in a few milliseconds (up to several thousand strokes per minute).<\/li>\n<\/ol>\n
