The brother who often uses the hammer may encounter the piston of the hammer to break, but the reason is not known, how can it cause the break? Quality also has a certain reason, perhaps all agreed that it is caused by fatigue, fatigue is also a major cause, but there are also weather, human inclusion factors in it. It also has a lot to do with operations.
To ensure that the hammer extends the service life, in addition to normal maintenance, but also remember the operation essentials, the butter is basically played within two hours is the best, keep the drill rod and piston impact surface lubrication, the piston is not easy to deformation, if the piston deformation will wear cylinder liner and oil seal, cylinder liner wear, will produce oil leakage, will also hit weak, cylinder liner wear is too large directly lead to the hammer scrap, The sleeve also reduces wear and the replacement cycle is extended.
When working on the hitting surface, such as not cracking within a minute, consider changing an Angle to hit, not for a long time, it is best to hit about 20 seconds to stop for a few seconds, a long time to hit easy to produce high temperature, often high temperature oil seal will accelerate aging and produce oil leakage, repair time error.
Ordinary hammer is the most taboo underwater operation, because there is no waterproof design, water and sand are particularly easy to invade the cylinder liner, flow into the hydraulic oil, resulting in oil pollution, hydraulic oil white, turbidity emulsification. Sand into the cylinder liner is easy to cause cylinder pulling, but also damage the hydraulic parts, do not!
When it is found that the sound of the hammer is dull or different from the usual, it cannot be forced to construct! Generally, the piston fracture will produce a dull sound, the pressure to the drill rod is relatively heavy, the piston has a crack, and the oil seal forced friction, feel heavy. The edge will be as sharp as a knife, and wear out the liner.
