How To Disassemble The Locomotive When It Is Overhauled (Part 1 Locomotive Dismantling)

Today, I would like to share with you how to disassemble thelocomotive during overhaul. Because there are many contents,electric locomotive I will break them into two parts to tell you. Let me first tell you how to dismantle the locomotive.

(1)Before demolition, it is necessary to understand and be familiarwith the locomotive's performance structure and relevant technical data. Unfamiliar locomotives should not be dismantled blindly without clarifying the assembly diesel locomotive structure and relevant locomotive technical data.

(2) Remove dirt and mud from the outside before disassembling, and put the oil and water in the net cleaner. To prepare the parts for storage locomotive diesel, place the parts in an orderly manner. Do not place them directly on the ground or pile them together. Fine and delicate parts should be washed as soon as possible, coated with anti-rust oil or immersed in diesel oil pots, and covered to prevent dust intrusion.

(3) Demolition should be carried out purposely.It is for inspection and repair. Therefore, it should be known and targeted before demolition. It is not necessary to disassemble the parts that can be determined to meet the technical requirements without disassembly inspection. If the oil pump passes the test on the test locomotive bench, if the oil supply of the oil press meets the technical requirements at a fixed speed, it means that the diesel locomotive oil pump meets the requirements and it does not have to be disassembled. Reducing unnecessary disassembly will not only reduce the workload but also extend the life of the parts. However, if it is difficult to confirm the state of the technology without dismantling, or if it is considered to be defective or suspect after preliminary inspection, it must be disassembled for further inspection or repair.

(4)There must be a certain sequence of parts removal. It is generally from the whole to the assembly, locomotive diesel from assembly to parts, from parts to parts, from outside to inside, from top to bottom, from simple to complex. However, the locomotive parts that are easily damaged should be removed first, which can ensure the smooth disassembly work.

(5)Use special tools and standard tools for disassembly to ensure that parts are not damaged and improve work efficiency. Such as the removal of nuts, electric locomotive bolts should use a variety of open wrenches and special socket wrenches, as far as possible without a spanner wrench, so as not to damage the corners of the nut. For parts that must be pulled out or pressed out with special tools, hammers or other items must not be smashed. When using vise and press, you must attach a soft cushion (such as copper plate, aluminum plate and wood plate) to the force surface of the machine to prevent damage to the machine.

(6) The removed parts such as bolts, nuts, pins, and washers should still be attached to the removed original parts to avoid misplacement or loss. If some parts should not be put back to the original position, you can use the wire to put on or tie up the cloth to indicate the site for installation.

(7) When disassembling relatively complicated, precise and important parts, be sure to remember the number, mark,locomotive direction and position of the parts.electric locomotive Pairs of fittings should be matched as they are to avoid mess.

(8)When disassembling the tight fittings, check whether there is any additional fixing position such as pins or screws. If yes, it should be removed first to prevent damage. When removing the rolling bearing from the shaft, the inner ring should be strengthened.diesel locomotiveWhen removing the rolling bearing from the housing, the outer ring should be forced. For tapered or shouldered parts, remove them in only one direction.

The above is how to disassemble the locomotive. Have you learned it? Well, let's stop here today. Let's see you next time.
