叉车齿轮泵修补技巧 : 叉车齿轮泵的修补是有必定的技巧,不能盲目的拆开而导致其他零部件的危害 ,依据齿轮泵装置方式•●、构造方式进行有序合理的拆卸,这样不只不会危害齿轮泵的零部件,还会敏捷的拆开。下面具体介绍叉车齿轮泵修补技巧分为以下几点:

  Forklift gear pump repair skills: Forklift gear pump repair is a certain skill, can not blindly disassemble and lead to the harm of other parts, according to gear pump device, structure, orderly and reasonable disassembly, so that not only will not harm gear pump parts, but also agile disassembly. Following is a detailed introduction of the repair techniques of forklift gear pump, which can be divided into the following points:
  1.叉车齿轮泵体:泵体磨损一般发生在吸油腔,某些油泵从构造上可用换位法进行修补,即将泵体绕本身轴线180°,使吸油腔变成压油腔以康复其作业能力。
  1. Forklift gear pump body: The wear of pump body usually occurs in the oil suction chamber. Some oil pumps can be repaired by transposition method in structure, that is, the pump body is about 180 degrees around its axis, so that the oil suction chamber becomes a pressure chamber to recover its operation ability.
  2.叉车齿轮轴承架:端面磨损或起线拉毛时,可将四只轴承架在平面磨床上,以非齿轮接触面为基准,一次将端面磨出。
  2. Forklift Gear Bearing Frame: When the end face is worn or the starting line is roughened, four bearings can be grinded out at one time on a surface grinder based on the non-gear contact surface.
  3.油泵齿轮都是单方向作业,因而齿面都是单面磨损?山菝婺ニ鸬某萋钟糜褪サ裘,调换齿轮啮合方位,可康复油泵的作业性能。
  3. Oil pump gears are all operated in one direction, so the tooth surface is worn on one side. It can remove burrs from worn gears with oil stones and change the meshing orientation of gears, thus rehabilitating the operation performance of oil pumps.
  4.齿轮两边端面磨损,轻者起线,可用研磨将毛刺痕迹研磨掉;磨损严重时,可在磨床上磨平。但只需一只齿轮端面磨损,另一只齿轮也需一起磨削,以确保两只齿轮的厚度差在0.005mm以内。磨削时还应留意端面与孔•●、端面与端面的精度要高。磨削后使用油石磨去锐边毛刺,但不宜倒角。
  4. The ends of the gears are worn and the lighter ones are started. The burr marks can be abraded by grinding. When the wear is serious, they can be abraded on the grinder. But as long as one gear face is worn, the other gear needs to be grinded together to ensure that the thickness difference between the two gears is less than 0.005mm. When grinding, attention should also be paid to the high accuracy of end face and hole, end face and end face. After grinding, the sharp edge burrs should be removed by oil stone grinding, but chamfering should not be used.

  5.内孔一般磨损较小,若磨损严重时,可用研磨或将孔径磨大至修补尺度•●、选配滚针。
  5. Internal holes generally wear less, if the wear is serious, can be used to grind or grind the aperture to repair scale, select and match needles.
  6.当齿轮因端面磨损而进行磨削后,为保持轴向空隙,需将泵体后端面磨至恰当厚度。
  6. When the gear is grinded due to the wear of the end face, in order to maintain the axial clearance, it is necessary to grind the back end face of the pump body to the appropriate thickness.
  7.叉车齿轮:齿轮外圆磨损及胶合,使径向空隙增大,轻者对使用无明显影响,可不比修补;严重者应予更换齿轮。
  7. Forklift Gears: The wear and gluing of the outer circle of the gears increases the radial clearance. The lighter one has no obvious influence on the use, and can not be compared with the repair. In serious cases, the gears should be replaced.
  8.不能用换位法修补的油泵体,可用镶铜套法修复。
  8. The oil pump body can not be repaired by transposition method, but can be repaired by copper-inlaid sleeve method.
  9.装有侧板或轴向浮动的轴套磨损•●、划伤和沟痕时,可将损害的表面进行抛光。方法是在滑润表面上放上NO.400-600的研磨膏,加上洗油或蜡在侧板表面上悄悄转动,进行抛光。
  9. The damaged surface can be polished when wear, scratch and groove of axle sleeve with side plate or axial floating. The polishing method is to put NO. 400 - 600 abrasive paste on the smooth surface, add washing oil or wax to rotate quietly on the side plate surface, and polish.
  因而,在叉车齿轮泵修补时必定不能盲目拆开,要有正确的修补
  Therefore, when repairing forklift gear pump, it must not be blindly disassembled and correct repairing must be done.
