Forklift gear pump repair of major parts

(1) Cylindrical gear wear and glue, so that the radial gap increases, the light of the use of no significant effect, better than repair; serious should be replaced gear. Face gear wear on both sides, the light from the line, the grinding can be used to grind off the burr marks; serious wear, grind on the grinder. However, as long as one gear wear, the other gear also need to grind to ensure that the thickness difference between the two gears within 0.005mm. Grinding should also pay attention to face and hole, face and face the higher accuracy. After grinding the oil stone to sharp edge burr, but not chamfering. Oil pump gear are one-way work, so the tooth surface are single-sided wear. Can be worn gear tooth stone removed with burrs, gear meshing orientation, can restore the performance of the pump. (2) When the end surface of the bearing frame is worn or the thread is peeled, the four bearing frames may be ground on the surface grinder with the non-gear contact surface as a reference, and the end surface is polished out once. The bore is generally less wear and tear, if the wear is serious, available grinding or grinding aperture to repair size, matching needle. Damaged surfaces can be polished when worn, scratched, and grooved with bosses or axially floating bushings. The method is to put No400-600 on the smooth surface of the abrasive paste, plus wash oil or wax on the surface of the side plate gently rotating, polishing. (3) pump body wear generally occurs in the suction chamber, some of the pump structure from the transposition method can be used to repair, about the pump body around its axis 180 °, the oil into the pressure chamber cavity to restore its ability to work. Can not be replaced with transposition method of the pump body, copper sleeve method can be used to repair. When the gear due to wear and tear after the end face, in order to maintain the axial clearance, the rear end of the pump body must be ground to the appropriate thickness.

Yangzhou Chengde is a Jointer venture company with American top Aerospace and Energy products conglomerate PCC Group, fully integrated with PCC on technology and management. We can produce all the boiler pipes according to the ASME SA335, ASTM A335 and EN10216 standards, such as the P11 steel pipe, P12 steel pipe, P22 steel pipe, P91 steel pipe, P92 steel pipe, P5 steel pipe, P9 steel pipe, P36 steel pipe, 10CrMo5-5 steel pipe, 10CrMo9-10 steel pipe, 13CrMo4-5 steel pipe, 15NiCuMoNb5-6-4 steel pipe, X10CrMoVNb9-1 steel pipe and X10CrWMoVNb9-2 steel pipe

In the year of 2015, we win the first prize of National Science and Technology Progress Award by the program of [The innovative research & development, and application of steel pipes used in 600 ℃ Ultra-super critical coal power generation unit".

Yangzhou Chengde is continuously strengthening the technical innovation, together with Bao steel and other companies. Yangzhou Chengde has spent 10 years on the R&D of the steel pipe used in 600 ℃ Ultra-super critical coal power generation unit and achieved the tremendous success on realizing the manufacture of such high-end seamless steel pipe from zero to the advance level, which has filled up the vacancy in China and broken up the foreign technological monopoly. The steel pipe manufacturing technology of China has leaped to the international advanced level and further confirmed the leading position of Chinese companies in researching and making high-end special steel pipes.
