Insulation gear pump the correct use and maintenance

Insulation gear pump is a high viscosity liquid conveying gear pump, the use of the following problems often occur, I hope users in the process of using attention to ensure that this product has an important role in the use of the industry fully reflect their own Value plays an important role. Insulation gear pump to be used in accordance with certain methods and principles, the need for routine use in the normal maintenance and care in order to make it work properly. Insulation gear pump in the event of failure how to properly maintain the fault and repair: 1, the active shaft bushing bore and driven shaft bore wear 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. 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. 2, the repair of the valve seat: 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. 3, Insulation gear pump cover repair work plane repair: If the pump cover wear a small work surface, manual grinding method can be used to eliminate wear marks, that is, put a little valve on the platform or thick glass plate sand, and then the pump cover on top Grinding until wear marks disappear, the work 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. 4, Insulation gear pump chamber cavity repair: Insulation gear pump chamber cavity wear, the general cavity set method to repair, is about to enlarging the cavity after the set with cast iron or steel bushings. Inlaid, the lining of the cavity.
