With regard to the manual hydraulic pump knowledge, in the above articles, we've had a lot of talk, I believe we have already have a basic knowledge of their mastery of hand pumps, understand the need to make full use of its preparatory work, so to be able to ensure the smooth progress of our work in this small series of its preparatory work needs to be done as follows: 1, before using the machine to check the manual pump voltage and check the plug and socket have not connected. 2, hand pump is connected to one end of the high-pressure hose connector on the unit syb-2a manual pump, the other end connected to the type of tool you want to use. 3. Please note ends before using quick connect fittings for locks in place, it must be hard to top in the end quick connectors non-standard manual pump, relax under the premise of not screwing coat nuts. If there is no oil there will not be locked in place by the phenomenon, which causes the machine to produce no action situations. 4, hand pump in the use frequently, replace the hydraulic oil once a year syb-1 manual pump, oil number is best to use numbers JIS22-32, or an equivalent number of oil. Actual flow manual manual hydraulic pump the oil flow and the actual series and parallel concerning: the series is equal to the oil flow throughout; while working in parallel the oil flow is equal to the sum of each strip the oil flow. In addition, single-rod hydraulic cylinder system, pay attention to the different return flow piston extended and retracted when: when there is no reduction in the flow of the rod chamber than when the lever back to the oil back to the oil chamber and extended, and more than two-chamber area of ??the same. syb-2-speed hydraulic hand pump _ quality (certified) _ Tongchuan hand pump provided by Dezhou City mass-velocity hydraulic machinery factory.
