RSM type thin jack, chrome piston, single-acting jack, spring retraction, the plunger surface trench without saddle, RSM-750, RSM-1000, RSM-1500 is equipped with portable handle, used for the main volume narrow place, in a small space construction site location, with good ability. RCS thin top is smaller than the volume by a high pressure hose is connected to the top and thin, enabling remote operation, the separation of the structure of the hydraulic roof repair and maintenance easy. Tonnage particularly complete. Light weight, large tonnage, mobile and flexible features. Mounting holes so fixed will be easy, paint surface to make corrosion-resistant. Under low speed hydraulic jacks creeping how to do? We use a hydraulic jack, there is always encounter this or that kind of symptoms, is to introduce today small creeping phenomenon on hydraulic jacks appear in the case of low-speed solutions. In the face of low-speed crawling under a hydraulic jack, in order to solve this problem, it is necessary from these aspects: pressure valve pressure instability, through manual jack when plugging orifice, pressure runout large, or adjust working pressure too low; the throttle valve unstable and in excess of the minimum stable flow valve; pump output flow ripple, Uneven supply; piston rod connected with the table aspherical deputy qf series jack, especially long cylinder due to other fresh produce crawling, transfer cylinders sealed at both ends too tight, high friction; hydraulic cylinder, outside a large leak, resulting in changes in cylinder pressure pulsation; lubricants stabilizer failure, resulting in unstable rail lubricants and sometimes stop. Failed to form friction 0. 005- 0. 008mm thick film (experience is full-length with your fingers scraped the rail surface, such as a hand attached dripping oil does not drip, the film thickness appropriate); lubricating pressure is too low, and Workbench and heavy; resonance line; hydraulic jack imported throttling manner and because no back pressure or back pressure adjustment mechanism, although a back pressure regulator or agency, but a back pressure regulator is too low, so low in some area most prone to crawl inside. Single-acting jack, jack Nanchong, Lu Lu hydraulic force provided by hydraulic equipment plant in Texas.
