      Shanghai Hanier Technology Co., Ltd. is a professional provider of industrial lubrication equipment and intelligent lubrication solutions. Hanil takes everyone to learn how to repair the gear oil pump?

      After the lubricant pump drive shaft and bushings are worn, repair the worn drive shafts and bushes and increase the clearance to affect the amount of pump oil. In this case, the normal fit clearance can be restored by repairing the drive shaft or bushing. If the drive shaft wear is very small, simply push out the old bushing and replace it with a standard size bushing, and the fit clearance can be restored to the allowable range. If the drive shaft and bushing are severely worn and exceed the assembly gap, not only the bushing needs to be replaced, but also the diameter of the drive shaft should be increased by chrome plating or vibration surfacing, and then ground to a standard size and in accordance with the recovery should be bushing. Oil pump casing crack repair can be repaired by casting 5, 8 nickel copper electrodes. The welding seam is tight, no air holes, and the flatness error of the joint surface with the pump cover is not greater than 0.05mm.

      The shaft hole is enlarged to the corresponding size, and the bushing is worn out from the shaft hole. The wear of the driven shaft was eliminated by the hinge method, and then the driven shaft was prepared according to the actual size of the hinge hole.

      After repairing the internal cavity of the pump casing, the internal cavity should be used to repair the internal cavity, that is, after the internal cavity is large, cast iron or steel bushings must be installed. After the bushing is finished, coat the inner cavity with the required size and grind the bushing protruding from the end face to make it flush with the pump brother.

      Maintenance valves and ball gate valves for pressure limiting valves are two types of cold relief valves. After the ball seat is worn, you can place the ball on the valve seat with a metal rod and then pat the ball gently. The ball valve and valve seat are tight. The valve seat is severely worn and the first hinge can be removed to remove the scar and then the bonding process can be performed. When the seat of the plunger valve is worn, it can be released with only a small amount of sanding.

      In order to give full play to the efficiency of automobile shock absorbers, improve ride comfort, improve mobility and stability, and further extend the service life of cars, timely maintenance should be performed in accordance with relevant regulations.



      When the oil storage tank is broken, it should be leveled or repaired; when the piston rod or cylinder error exceeds 0.1mm, if the cylinder fit clearance exceeds 15mm or a groove appears, the piston or standard piston ring should be replaced. When the piston rod or cylinder error is greater than 0.1mm, if the cylinder gap is greater than 15mm or grooves appear, the piston or standard piston ring should be replaced, and the piston or standard piston ring should be replaced. The matching clearance between the piston and the cylinder should be 0.4, 0.065mm, and the port clearance should be 4. Prior to assembly, all parts should be cleaned with alcohol or shock absorbers and assembled in the reverse order of disassembly. When installing connecting rod oil seals, you must protect the edges of the oil seals and point the edges of the oil seals toward the piston. If the oil is installed backwards, the oil will leak quickly. When assembling the piston, do not squeeze the circulating work surface. If the working surface of the pump cover is less worn, you can remove the wear marks by manual grinding, that is, put a little valve sand on the platform or thick glass plate, and then cover the pump cover for polishing until the wear marks disappear. Eliminates, and smooth work shoulder surface. When the working depth of the bridge cover working surface exceeds 0.1mm, it should be repaired by turning before grinding.

      Pump drive shaft bushing hole cover Wear of drive shaft bushing hole cover is the same.

      The wear of the lubricating oil pump gear is mainly concentrated on the tooth thickness, while the wear of the gear end and the tooth tip is relatively small. The gear is worn on the rough surface of the teeth, so it can be used 180 degrees. When the end face of the gear is worn, it can be ground flat, and the mating surface of the pump casing is ground and lubricated to ensure that the gap between the end face of the gear and the pump cover is within the standard range. range. After the parts on the valve plate of the distribution valve and the return valve are installed on the support seat and the piston rod, the damping fluid should be filled. The liquid is composed of 50% transformer oil and 22 # turbine oil. The capacity of model 1091 is 37 ml, the capacity of model 1090 is 370 ml, and the capacity of model 1091 is 39 ml, which is 2. The refueling capacity of Type 2 cars is 250 ml.

      Pull the connecting rod assembly to a relatively high position and tighten the fuel tank nut with a special wrench. At this point, the piston rod should be able to slide freely without getting stuck. After assembly, the shock absorber is usually pulled up and fully resistant to downward compression.
