FIG Hengyu hydraulic equipment, hydraulic electric pump designed Hengyu 1, the electric pump

Single-action self-resetting hollow cylinder (hollow hydraulic cylinder) with a single action self-resetting, structure and function of various forms of double effect, flat, hollow and so on. It has the versatility, output tonnage, and other characteristics. Single-acting cylinder equipped with a single outlet self-resetting manual or electric pumps, especially for lifting, straightening and assembly operations. Small space for other standard flat cylinder oil port constrained, portable, for leveling, jacking, maintenance operations. Hollow hydraulic cylinder addition to the general characteristics, the middle through-hole may expand the scope. Today we have a problem the majority of high pressure electric pump users are more concerned to explain to you the specific, this issue is mainly commissioning work on the high pressure electric pump before formal operation. For this, some users may not quite understand the reference standard, for today we focus on knowledge to explain to you in this regard. As follows: Under normal circumstances, we learned that the high pressure electric pump in the actual test run two to three hours, as a final check, if no adverse phenomenon during, then we can be sure that qualified for the installation. In addition, we also learned that what we want to correct the high pressure electric pump shaft and motor shaft concentricity before running, on the road linking the outer shaft, deviation allowable range ≤0.1mm; two couplings space plane should ensure 2 ~ 4mm, the gap to the average, tolerance of 0.3mm. In addition to the above points, we need to note in particular that the high pressure electric pump unit on the foundation anchor bolts buried on between the base and the base with a pair of chocks with calibration.
