叉車齒輪泵修補技巧 : 叉車齒輪泵的修補是有必定的技巧,不能盲目的拆開而導致其他零部件的危害 ,依據齒輪泵裝置方式、構造方式進行有序合理的拆卸,這樣不只不會危害齒輪泵的零部件,還會敏捷的拆開。下面具體介紹叉車齒輪泵修補技巧分為以下幾點:

  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.叉車齒輪泵體:泵體磨損一般發生在吸油腔,某些油泵從構造上可用換位法進行修補,即將泵體繞本身軸線180°,使吸油腔變成壓油腔以康復其作業能力。
  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.叉車齒輪軸承架:端面磨損或起線拉毛時,可將四只軸承架在平面磨床上,以非齒輪接觸面為基準,一次將端面磨出。
  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.油泵齒輪都是單方向作業,因而齒面都是單面磨損。可將齒面磨損的齒輪用油石去掉毛刺,調換齒輪嚙合方位,可康復油泵的作業性能。
  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.齒輪兩邊端面磨損,輕者起線,可用研磨將毛刺痕跡研磨掉;磨損嚴重時,可在磨床上磨平。但只需一只齒輪端面磨損,另一只齒輪也需一起磨削,以確保兩只齒輪的厚度差在0.005mm以內。磨削時還應留意端面與孔、端面與端面的精度要高。磨削后使用油石磨去銳邊毛刺,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.內孔一般磨損較小,若磨損嚴重時,可用研磨或將孔徑磨大至修補尺度、選配滾針。
  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.當齒輪因端面磨損而進行磨削后,為保持軸向空隙,需將泵體后端面磨至恰當厚度。
  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.叉車齒輪:齒輪外圓磨損及膠合,使徑向空隙增大,輕者對使用無明顯影響,可不比修補;嚴重者應予更換齒輪。
  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.不能用換位法修補的油泵體,可用鑲銅套法修復。
  8. The oil pump body can not be repaired by transposition method, but can be repaired by copper-inlaid sleeve method.
  9.裝有側板或軸向浮動的軸套磨損、劃傷和溝痕時,可將損害的表面進行拋光。方法是在滑潤表面上放上NO.400-600的研磨膏,加上洗油或蠟在側板表面上悄悄轉動,進行拋光。
  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,在叉車齒輪泵修補時必定不能盲目拆開,要有正確的修補
  Therefore, when repairing forklift gear pump, it must not be blindly disassembled and correct repairing must be done.
