Analysis of the phenomenon of insufficient power of the forklift engine: it may be caused by waterway problems

Phenomenon: 　　1) The power is insufficient under engine load; 　　2) The pressure reducing valve is frosted.　　Analysis: 　　1) As the water pipes flowing through the pressure reducing valve are blocked, the heat circulation of the water circuit can not flow to the pressure reducing valve, causing the pressure reducing valve to frost (touch the pressure reducing valve pipe with your hand, and it feels very cold). Solution: 　　1) Remove the water outlet pipe of the pressure reducing valve, and find that there is no water flowing out, indicating that the road is blocked; 　　2) Remove the pressure reducing valve inlet pipe, there is a lot of hot water flowing out, use the mouth to blow the pressure reducing valve inlet pipe and find that it cannot be blown It means that the water inlet pipe to the water outlet pipe is blocked; 　　3) Since the pressure reducing valve has been in a frosting state before, it should be that this section of the waterway freezes and blocks the water pipe, only the waterway is blocked, and hot water is poured on the pressure relief valve to reduce pressure. The ice inside the valve melts, and then blow with the mouth, the waterway is unobstructed; 　　4) After the waterway is unblocked, the pressure reducing valve works normally, but the engine is still insufficient under load. Adjust the concentration adjustment screw of the single fuel mixer to increase the concentration of the mixer, and then the vehicle will have a strong power under the load state.
How to lubricate the lithium pallet truck clutch release bearing?
During use, the release bearing of the internal combustion forklift clutch works very frequently, and the number of damages accounts for a large proportion of the forklift failures! The editor of Hangzhou tells you: How to add lubricating oil to the forklift clutch release bearing? If the driver's operation is good, the bearing can be used for about 3 months, but it must be updated in the middle of repair! If the driver's operating skill level is low, the forklift that he drives will have the release bearing damage almost every month, and other parts such as the release lever and clutch plate will be damaged after damage. So here comes the problem! What is the reason why the clutch release bearing is easily damaged? In practical experience, although the driver has been strictly required to drip oil once a day on the release bearing, this is not only cumbersome to operate, but the bearing is still often damaged. After analysis, it is believed that because the high temperature of the engine is transmitted to the release bearing, and the high-speed rotation of the bearing will also produce high temperature, it is difficult for the lubricating oil to remain in the bearing under such conditions. The bearing works continuously at high temperature, and the lubrication conditions are not good. , Resulting in frequent damage to the release bearing. According to the above problems, it has also been tested to heat the bearing in the grease to make the grease soak into the bearing. After this treatment, although the grease can fill the bearing, the structure of the grease after high temperature treatment is damaged, its performance It is greatly reduced, the effect of using this method is not ideal, and the service life of the bearing has not been extended. A sharp-nosed grease gun was also used to directly grease the release bearing.
