Stainless steel arc insulation gear Pump in use there will be some use fault, I hope the user in the use of strict attention to the need for routine use in the normal maintenance and care to ensure that can have an important role in the use and value can In the industry to play an important performance and value. First, stainless steel arc insulation gear pump repair work plane repair: If the pump cover wear a small work surface, available manual grinding method to eliminate wear marks, that is, put a little glass or Valve plate on the platform sand, and then the pump cover Grinding on the above, until the wear marks disappear, the working surface so far. When the pump cover working surface wear depth of more than 0.1 mm, should be taken after the turning grinding method to repair. Second, stainless steel arc insulation gear pump chamber cavity repair: Insulation gear pump chamber cavity wear, the general cavity set method to repair, about to enlarging the cavity enameled with cast iron or steel bushings. Inlaid, the cavity enamel 5, the valve seat repair: pressure limiting valve with a ball valve and plunger valve two. 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. Third, the active shaft bushing bore and driven shaft hole wear repair: drive shaft bushing hole wear, the reaming method can be used to eliminate wear marks, and then increased with the appropriate size to the bushing. Slave shaft hole wear is also reaming method to eliminate wear marks, and then press the hole reaming the actual size of the preparation of the driven shaft. Shell cracks available 508 cast nickel-copper welding electrode. Welds to be close and the yuan stomatal, and insulation gear pump cover with flat surface error of not more than 0.05 mm. Stainless steel arc gear pump active shaft and bush wear, with the gap increases, will certainly affect the pump oil. In this case, you 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.
