200t jacks | Hydraulic Lu (certified) | Zhongshan Lu jack provided by the Texas Hydraulic machinery plant. Texas Lu force hydraulic machinery plant (www.luliyeya.com) is specialized in "jacks, electric pumps, hand pumps, cylinders," the business, the company adhering to the "honesty, hard service" concept, to provide you with the highest quality products and service. Welcome to inquire! Contact: Lu Jingli. The main reason hydraulic jacks crawling phenomenon is the driving force and executive body system pressure on the actuator suffered resulting in a critical state of equilibrium resistance, moving parts in the static friction and dynamic friction of alternation, jitter phenomenon. Hydraulic competing for everyone summarizes several treatment methods 400t Jack, I hope this article can help to you. 1) cylinder air intrusion. Should additional exhaust jack or hydraulic cylinders with the greatest stroke of rapid movement, forced exclusion of air. 2) The head of the hydraulic cylinder seals too tight or too loose. Should be adjusted to give it a proper seal tightness and ensure smooth rod can be pulled back and forth by hand without leakage. 3) the direction of the piston and piston rod coaxial bad. Should be corrected, adjusted. 4) After installing the hydraulic jack is not parallel with the rail direction. Should be adjusted or re-install. 5) The rod bent. Should straightening rod. 6) The difference between the rigid rod. Increase the piston rod diameter. 7) The clearance between the cylinder moving part is too large. With the gap should be reduced. 8) the mounting position of the hydraulic jacks offset. Parallel cylinders should be checked with the rail and corrected. Brief hydraulic jack handle crawling method of hydraulic jacks eight crawling is a situation we will encounter 1000t jack, it is a lot of consumers are more troublesome phenomenon, then 600t jacks, hydraulic jacks crawling how to deal with the phenomenon it? Xiaobian for you summed up the eight. First, the end cap of the hydraulic cylinder seals too tight or too loose. Seals should be adjusted so that there is proper tightness to ensure that the rod can be pulled by hand back and forth smoothly without leakage. Second, the piston rod poor rigidity. Increase the piston rod diameter. Third, the rod bent. Should straightening rod. Fourth, the gap between the cylinder moving part is too large. With the gap should be reduced. Fifth, hydraulic jacks offset mounting position. Parallel cylinders should be checked with the rail and corrected. Sixth, the piston and piston rod coaxial bad. Should be corrected, adjusted. Seven-cylinder air intrusion. Exhaust should be added, or the maximum stroke of the hydraulic cylinder with fast motion, forcing the exclusion of air. Eight, hydraulic jacks are not parallel with the rail after installation. Should be adjusted or re-installed.
