JB cylinder speed characteristics with the schedule

JB cylinder this unit, for we should be very familiar with, because the front has been introduced its related aspects, but learning is a never-ending, knowledge are constantly updated and development, so we study the cylinder can't slack off or stop, should continue to proceed. So, in order to implement this idea, today or to introduce cylinder related knowledge, as to what is, after you read this article understand, here is not to generalize. , JB cylinder speed characteristic, first of all, let's look at what is theoretical benchmark rate. Theory reference speed, it is to point to in cylinder without external load, and assuming that the exhaust exhaust side for sound, air pressure is not very low, the calculation of cylinder speed is then called the theory of benchmark rate. General recognition of the maximum speed of cylinder without load for theory reference speed. But as the load increases, the maximum speed of cylinder will gradually decrease. JB at the average speed of cylinder, it is the ratio of the moving distance and the action time of the cylinder, it has to do with the relationship between the maximum velocity is: the maximum velocity to average velocity. Times. Generally speaking, the speed range of the standard cylinder, mm/s。 Speed is too small, can make the crawling phenomenon in a cylinder, but if the speed is too large, will speed up the process of wear parts, make the cylinder easy to leak, shorten its service life. As a result, too much or too little is bad, should choose the most appropriate, and within the prescribed scope. , JB cylinder stroke of JB cylinder stroke, the general is the use of cylinder and occasions, and stroke than. If the installation of the cylinder form is different, so their trip than is also different, so should be kept separate, accurately determine the well.
