Maintenance method of gear pump for manual pallet truck

If a pallet truck has been used for more than five years, and the frequency of use is high. Due to the normal aging of the electrical parts and the normal wear and tear of the mechanical parts of the manual pallet, the comprehensive condition of the manual pallet is declining, and the maintenance cost is bound to increase year by year. Each emergency repair can only solve some or current problems. With the continuous use of vehicles all the year round, the overall situation is declining, at the same time, the safety performance of the vehicle will inevitably decline. At this time, the safe use of pallet trucks is the most concerned and most worried problem for customers. Overhaul work can relieve such concerns for customers.            

The benefits of overhaul can be manifested in the following aspects:            

1.  By modifying the comprehensive situation of manual pallet trucks, increasing the service life of pallet trucks, reducing the frequency of re-purchasing manual pallet trucks, and reducing costs.            

2.  Reduce the maintenance rate of the manual pallet truck through overhaul, thereby reducing the parking time of the manual pallet truck, increasing the continuous use time, increasing the utilization rate of the manual pallet truck, and reducing the cost of the pallet truck. In addition, it also reduces the work of managers.            

3.  Improving the safety of manual pallet truck through overhaul can reassure the use of pallet truck and avoid unnecessary losses caused by potential safety hazards.           

4.  After overhaul, the service life of the old car can be prolonged by 30%-50%. Generally speaking, the service life of industrial vehicles is 5 years. It is very advantageous for cost control to extend the service life of old vehicles after overhaul.            

5.  Manual pallet truck gears: the wear and gluing of the outer circle of the gears increases the radial clearance. The lighter one has no obvious influence on the use, and can not be compared with repair; the heavier one should be replaced.            

6.  The ends of both sides of the gears are worn out, and the lighter one starts the line. The burr marks can be abraded by grinding. When the wear is serious, the burr marks can be abraded by grinding on the grinder. But as long as one gear face is worn, the other gear needs to be grinded at the same time to ensure that the thickness difference between the two gears is less than 0.005mm. When grinding, attention should also be paid to the high accuracy of end face and hole, end face and end face. After grinding, the sharp edge burrs should be removed by oil stone grinding, but chamfering should not be used.            

7. The gear of oil pump works in one direction, so the tooth surface is worn on one side. It can remove burrs from worn gears with oil stones and change the meshing direction of gears, thus restoring the working performance of oil pumps.            

8.  Hand Pallet Gear Bearing Frame: When the end face is worn or the starting line is roughened, four bearings can be grinded out at one time on a surface grinder based on the non-gear contact surface.            

9.  Internal holes generally wear less, if the wear is serious, can be used to grind or grind the aperture to repair size, select and match needles.            

10.  The damaged surface can be polished when wear, scratch and groove of axle sleeve with side plate or axial floating. The polishing method is to put no400-600 abrasive paste on the smooth surface, add washing oil or wax to gently rotate on the side plate surface, and polish.
