YHB lubrication of gear pump shaft and bush wear repair, I plant YHB lubrication gear pump, YHB vertical gear pump, YHB vertical gear pump drive shaft and bush wear, the increase with the gap will inevitably affect Pump oil volume. In this case, YHB lubrication gear pump can repair the drive shaft or bushing method to restore its normal with the gap. If the drive shaft wear slightly, simply press the old bushing and put on the standard size bushing, with the gap can be restored to the allowable range. If the drive shaft and bushing wear serious and serious with excessive clearance, not only to replace the bushing, and the drive shaft also applies chrome or vibration welding method to increase its diameter, and then grinding to the standard size, recovery and bushing With the requirements. Repair of YHB Lubricated Gear Pump Housing Repair of Housing Crack: Gear Forged 22X14,Forged Aluminum Rims,Black Audi Rims,Chrome Alloy Wheels NINGBO KINTOP AUTOPARTS CO., LTD. , https://www.wheelmake.com
Shell cracks can be cast 508 nickel-copper welding electrode repair. Welds to be close and yuan stomatal, with the flatness of the pump cover with no more than 0.05 mm flatness.
Drive shaft bushing hole and driven shaft wear and tear repair: Drive shaft bushing hole wear, the reaming method can be used to eliminate wear marks, and then with increased to the appropriate size of the bushing. Followed by wear and tear of the shaft shaft wear to eliminate traces of wear and tear, and then press the actual size of the hole after the preparation of driven shaft pump chamber cavity repair: pump housing cavity wear, the general approach to repair the lumen, After the enlarging of the inner cavity is set with cast iron or steel bushings. After setting the sleeve, the cavity enamel to the required size, and wear out the end face of the liner to flush with the pump housing surface.
Seat Repair: Pressure limiting valve has two kinds of ball valve and plunger valve. Ball seat wear, the ball can be placed on a valve seat, and then gently tap the metal ball, until the ball valve and valve seat so close. If the valve seat is worn seriously, first remove the worn marks by reaming, and then use the method to make it close. Plunger seat wear, you can put a little valve sand grinding until close together.
With the growth of the use of time, gear YHB lubrication pump gear pump will appear inadequate, or even pump failure, mainly due to excessive wear and tear parts. Gear pump wear parts are the main shaft and bushings, passive gear center hole and shaft pin, pump housing cavity and gear, gear end face and pump cover. Lubricating oil pump wear of its main technical indicators fail to meet the requirements, it should disassemble, find out the location and extent of wear and tear, to take appropriate measures to be repaired.
