1, gear pump drive shaft and bushing repair after wear
Gear pump drive shaft and bush wear with the gap increases, will certainly affect the pump oil.This situation can repair the drive shaft or bushing method to restore its normal fit clearance.If the drive shaft wear slightly pressure Replace the standard bushing after the old bushing, with the gap can be restored to the allowable range.If the drive shaft and bushing wear serious and serious with the gap not only to replace the bushing, and the drive shaft also applies chrome or vibration Surfacing method to increase its diameter, and then grinding to the standard size, with the bushing to restore the requirements.
2, the repair of the lubricating oil pump shell crack repair
Oil pump shell cracks 508 cast nickel-copper welding electrode weld should be close to the hole with the pump cover the flatness error of not more than 0.05 mm.
3, gear pump drive shaft bushings and driven shaft hole wear repair
Oil tank truck gear pump drive shaft bushings bore hole can be used to eliminate wear traces after reaming method, and then with increased to the appropriate size of the bushing. Driven shaft hole reaming method to wear and tear to eliminate wear marks and then reaming The actual size of the hole configures the driven shaft.
4, gear pump pump cavity cavity repair
Gear pump pump housing lumen wear after the general use of the lumen inlaid method to repair, the cavity is enameled big set with cast iron or steel bushings. After setting the cavity lining, seat repair: pressure limiting valve with ball valve And the plunger valve two spherical seat wear a ball on the valve seat, and then gently tap the metal ball until the ball valve and valve seat so close, such as the valve seat wear serious first Reaming to remove the wear marks and then use the law to make it close.Lock valve seat wear can be put into a little valve sand grinding until the close.
5, gear pump cover repair
Oil pump work plane repair: If the KCB gear pump pump cover wear a small work surface, manual grinding method can be used to eliminate wear marks, that is, put a little valve in the platform or thick glass sand and then put the pump cover on the grinding until worn Traces to eliminate the work surface until smooth.When the pump cover working surface wear depth of more than 0.1 mm should be taken after the first turning grinding method to repair.
Construction hoist is vertical transport machinery driving by pinion and rack, mainly used on construction site for transportation of personal and materials. As a permanent or sub-permanent external elevator, it also applies to store house, dock, high tower, high chimney, etc.
There are single cage and double cages hoist. According to the need gets rid of one cage of double cages the hoist will be changed to single cage hoist. SC Construction Hoist is equipped with reliable electrical and mechanical safety device. It is efficient and safety vertical transporting equipment.
Spare parts for a construction hoist may include:
1. Wire Rope: These are used to lift and lower the load in the hoist. They may need to be replaced if they become worn or damaged.
2. Construction Hoist Motor: The motors in the hoist are responsible for powering the lifting and lowering mechanism. Spare motors may be needed in case of motor failure.
3. Electromagnet Brake: The hoist is equipped with brakes to hold the load in place. Spare brake pads or other brake components may be necessary for maintenance or repair.
4. Control panels: The control panel is used to operate the hoist and control its movements. Spare control panels or control panel components may be required in case of malfunction.
5. Safety devices: Construction hoists are equipped with various safety devices, such as limit switches, overload protection, and emergency stop buttons. Spare safety devices may be needed to ensure the hoist operates safely.
6. Bearings and bushings: These components help reduce friction and facilitate smooth movement in the hoist. Spare bearings and bushings may be necessary for maintenance or repair.
7. Electrical components: Various electrical components, such as relays, switches, and fuses, may need to be replaced if they fail or become damaged.
8. Pulleys and sheaves: These components are used to guide and redirect the wire ropes in the hoist. Spare pulleys and sheaves may be required if they become worn or damaged.
9. Hooks and shackles: The hooks and shackles are used to attach the load to the hoist. Spare hooks and shackles may be needed if they become worn or damaged.
10. Construction Hoist Steel Structure parts: Spare structural components, such as beams or mast sections, may be required for repair or replacement if they become damaged or worn over time.
