When the gear pump drive shaft and the bushing wear, the matching clearance increases, which will affect the pump oil. In this case, the drive shaft or bushing can be used to restore the normal fit clearance. If the drive shaft wears slightly, only the pressure is required. After the old bushing is replaced, the standard size bushing is replaced, and the clearance can be restored to the allowable range.
1. Repair of gear oil pump drive shaft and bushing after wear
When the gear pump drive shaft and the bushing wear, the matching clearance increases, which will affect the pump oil. In this case, the drive shaft or bushing can be used to restore the normal fit clearance. If the drive shaft wears slightly, only the pressure is required. After the old bushing is replaced with the standard size bushing, the clearance can be restored to the allowable range. If the drive shaft and bushing are seriously worn and the clearance is seriously exceeded, the bushing must be replaced, and the drive shaft should also be chromed or vibrated. The surfacing method increases the diameter and then grinds it to the standard size, recovery and bushing requirements.
2. Repair of cracks in the repair of the lubricating oil pump housing
The crack of the oil pump casing can be repaired by casting 508 nickel-copper welding rod. The weld seam must be tight and the flatness error of the joint surface of the element air hole and the oil pump pump cover is not more than 0.05 mm.
3. Repair of gear oil pump drive shaft bushing hole and driven shaft hole wear
After the oil tank drive oil pump drive shaft bushing hole is worn, the reaming method can be used to eliminate the wear marks, and then the bushing is enlarged to the corresponding size. The driven shaft hole wear is also removed by the reaming method and then reamed. The actual size of the hole is configured as a driven shaft.
4. Repair of the inner cavity of the gear pump casing
After the inner cavity of the gear pump casing is worn, it is generally repaired by the inner cavity inserting method. The inner cavity is enlarged and then the cast iron or steel bushing is inlaid. After the insert is set, the inner cavity and the valve seat are repaired: the pressure limiting valve has a spherical valve. And the plunger valve. After the spherical seat is worn, a steel ball can be placed on the valve seat, and then the steel ball is lightly tapped with a metal rod until the ball valve is in close contact with the valve seat. Reaming removes the wear marks and then closes them by the above method. After the plunger seat is worn, a small amount of valve sand can be placed for grinding until it is tight.

Plastic geogrid is made from high density polyethylene (HDPE). It meets the ISO 9001 standard. Plastic geogrid is characterized by good corrosion resistance and high junction efficiency. Divided by shapes, this product mainly has three types: biaxial plastic geogrid, uniaxial plastic geogrid and triaxial plastic geogrid. Plastic geogrids can effectively prevent soil erosion, ground subsidence and water pollution. It is extensively used to reinforce soil structure and prevent ground rupture.
