Insulation gear pump in the use of often the following failures, users hope that in the use of strict attention to ensure that can have an important role in the use and value, can play an important role in the industry performance and value. Insulation gear pump in use according to certain methods and principles of use, to ensure that in a certain industry to demonstrate the good role and value, the need for routine use in the normal maintenance and repair, to show in the field of industry important Performance and value. Insulation gear pump often in use, there will be some failure, in the event of failure of the fault for good maintenance and repair, to ensure that in the area can produce important performance and value. 1, drive shaft bushing hole and the driven shaft is not greater than 0. Hole wear repair: Drive shaft sleeve hole wear, available hinge side 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 method to eliminate signs of wear, and then equipped with increased to the corresponding size of the pump cover with a flatness of 05 mm error. 2, the repair of the valve seat: pressure limiting valve has two kinds of ball valve and plunger valve. Gently tap the ball with a spherical rod until the ball valve and seat are in close contact. 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: Working plane repair: If the pump cover wear a small plane, the available hand, that is, put a little valve on the platform or thick glass plate sand, and then grinding method to eliminate signs of wear will pump cover Grinding above, until the wear marks disappear, the working surface so far. Face wear depth of more than 0.1 millimeters When the pump cover work square meters, should be taken after the first turning grinding method to repair. 4, insulation gear pump cavity cavity repair: Insulation gear pump cavity wear, a large enamel cast iron or steel bushings. Inlaid, the enamel-like cavity to be used to set the inner sleeve method of repair, about the cavity.
Role of sleeper:
1. Bear the load, transverse force and longitudinal horizontal force transmitted from the rail, and distribute them evenly on the track bed;
2. Connect the two rails together to fix the rail position and keep a certain distance (gauge);
3. Fix the direction of the railway so that the railway will not have longitudinal and transverse displacement due to the force
