Maintenance method of gear pump of electric storage pallet truck

Drivers and friends of electric storage pallet trucks will all have the idea that they can all solve simple pallet truck problems. In this way, it can save costs, and more importantly, it can reduce the waste of time and avoid affecting the work process. Because we all understand one thing, that is, when we make an appointment for maintenance personnel, we may not be able to be in place in time, which will delay our work. The gear pump of the pallet truck is a relatively problem-prone part. Let's take a look at the related problems.

1. The wear and gluing of the outer circle of the pallet truck gear will make the radial gap larger. If it is not very serious, it is not necessary to repair it, but if the situation is serious, it must be repaired. The electric storage pallet truck has changed gears.

2. If there is wear on both sides of the gear, if the starting line is not very serious, you can use grinding to grind off the burr marks, but if the wear is serious, it can be ground on a grinder, and the end face of one gear is worn , the other gear also needs to be ground at the same time, to ensure that the thickness difference between the two gears is within 0.005mm. When grinding the gears of the electric storage pallet truck, attention should also be paid to the high precision of the end face and the hole, and the end face and the end face. After grinding, whetstone should be used to remove sharp edges and burrs, but chamfering should not be performed.

3. The oil pump gears of the electric storage pallet truck all work in one direction, and the tooth surfaces are worn on one side. Remove the burrs from the worn gears with whetstone and replace them. The gear meshing position restores the working performance of the oil pump. The inner hole is generally not worn very much. If the wear is serious, it can be ground or the hole diameter can be ground to the repair size, and needle rollers can be selected.

4. The wear of the gear pump body of the electric storage pallet truck generally occurs in the oil suction chamber. Some oil pumps can be repaired by the transposition method. The pump body is 180° around its own axis, and the oil suction chamber becomes the oil pressure chamber. , to restore its working capacity. Remember that the oil pump body that cannot be repaired by the transposition method is recommended to be repaired by the copper sleeve method.

5. When the end face of the gear bearing frame of the electric storage pallet truck is worn or the wire is roughed, the four bearing frames should be placed on the surface grinder, and the end face should be ground at one time with the non-gear contact surface as the benchmark. When the gears are ground due to end face wear, grind the rear end face of the pump body to an appropriate thickness.
