  • How to clean forklift parts and batteries?
    How to clean forklift parts and batteries?

    The various operating systems of the forklift are connected by many components and work together to maintain the normal operation of the forklift. Excessive dust will cause blockage of parts and affect the operation of various systems of the forklift. Minor failures may cause forklift operation problems, and major failures may cause engineering accidents. Therefore, we should clean the parts of the forklift regularly. At the same time, we can also replace some wearing parts. Now let me talk to you about the cleaning of forklift parts and batteries. 1. For the cleaning of some metal parts of forklifts, we usually use cold washing and hot washing methods. 1. The cold washing method is to use kerosene. It is quick. After washing with light diesel or gasoline, blow dry with compressed air. The equipment required for this cleaning method is very simple. The operation is also very fast. 2. The hot washing method is to clean with alkali solution and heat the solution. Then the parts are soaked and taken out, rinsed with clean water, and then dried with compressed air. In order to prevent corrosion of aluminum alloy parts, it cannot be cleaned with a solution containing a large amount of sodium hydroxide. 2. For the cleaning system sealing ring of some non-metal forklift parts on the forklift, use alcohol. The cleaning of rubber parts, such as brake cups, turpentine or brake fluid. Do not use kerosene. Rubber ring. It should be cleaned with hydraulic gasoline or alkaline solution to prevent swelling and deterioration. The clutch friction plate and brake friction plate can not be boiled and washed with alkaline solution, and should be cleaned with a little gasoline. Leather parts (such as oil seal aprons, etc.) are generally cleaned with a dry cloth. 3. The common dirt on forklift parts also has a black solid-it is gradually formed under high temperature and high pressure, and firmly adheres to the surface of internal combustion engine pistons, cylinder liners, cylinder heads and other parts. The texture is extremely hard. Carbon deposits must be removed during repairs. In order to ensure the normal operation of the forklift, the carbon deposits on the parts must also be removed regularly. We usually clean up this kind of dirt in two ways: 1. One is physical cleaning, that is, scraping with a spatula, spatula (or with a bamboo chip), metal brush, etc. This method of manually removing carbon deposits is inefficient and difficult to remove. If you are not careful, it will damage the parts. 2. There is another way to remove carbon deposits by chemical methods. The solution for removing the carbon deposits of internal combustion engine parts is prepared: then soak the carbon deposits of the parts in the cleaning solution. If there is a heating device, it can easily soften the dirt, and the solid dirt can be easily peeled off after the soaking is over. The battery of an electric forklift can be washed with water, but water cannot enter the battery cell. Try to...

Troubleshooting method: Adjust the oil supply of each cylinder to be even, repair the flower and replace the needle valve of the injector, and fix the fork screw. Reason 2: The gap between the shift fork and the adjustment is too large, and the steel ball and sliding plate are worn and dented. Troubleshooting method: Replacement parts Reason 3: The axial movement clearance of the camshaft of the fuel injection pump is too large. Troubleshooting method: Adjust with copper spacers Reason 4: Sliding disc bushing block Troubleshooting method: Clean, repair or replace Reason 5: The oil level rises-the cylinder liner sealing ring is damaged Troubleshooting method: Replace the sealing ring Reason 6: Engine oil level rises-cylinder head gasket leaks Troubleshooting method: Replace cylinder head gasket Reason 7: Rising oil level-water leakage in cylinder head or body Troubleshooting method: Maintenance and replacement
