1, "to meet a law" assembly is simple and easy In agricultural transport vehicle maintenance, some parts can take "to meet a" assembly method, that is, in accordance with the largest (or the smallest) position assembly, generally can also meet the minimum (or maximum ) The need for location. This is the case, for example, in the adjustment of a single-cylinder diesel engine governor. After the diesel engine has been used for a long period of time, in order to maintain a proper amount of starting oil and a minimum amount of fuel, the adjustment screws of the governor must be checked and adjusted as necessary. The method is: to open the governor flying hammer to the maximum position, while pushing the speed adjusting fork to stop the oil supply position, and then screw in or out the adjustment screw, so that it just touches the end of the speed control shaft, and then Turn the adjusting screw into 0.8 to 1 turn and fasten the hex nut. After such assembly, not only can stable idling be achieved, but also the need for rated oil supply can be met. 2. When using the bolt head to disassemble and install the socket head cap screw, when the socket head cap screw is disassembled, if the hexagon socket wrench with the corresponding specifications is missing, you can find a bolt of the right size, place the head into the countersunk socket head cap screw and put it on the bolt. Twist the two nuts and tighten them. Then use a wrench to remove the lower one nut and remove the Allen screw. If you want to tighten the Allen screw, just screw the upper nut. 3. When the valve clearance adjustment screw is not long enough When adjusting the valve clearance of the engine, if the valve clearance adjustment screw has been screwed up to the end and the specified clearance value is still not reached, the lock nut of the adjustment screw can be used. Swap the position, that is, under the tail of the installed rocker arm, or under the rocker shaft bearing under a layer of steel pad, so that the distance between the rocker arm and the valve rod end is increased. 4, impregnated seals can improve the sealing performance In order to improve the sealing performance of the machine, some seals to take oil or soaked in water, can play a good effect. (1) Paper pad. In places with low oil pressure, such as the front and rear covers of gear housings, clutch housings, transmission covers, and final drive housings, the paper mats can be soaked in warm water for about 2 minutes until they can be printed out with the nails. Remove it and apply a quick-drying paint on both sides of the paper pad before installation. This will effectively prevent oil leakage. If it is a white paper pad, cook it in oil first, and the leakage prevention effect is also good. (2) Leather seals. Before installation, the leather seal can be immersed for about 10 minutes in a mixture of oil and kerosene at a temperature of about 60°C. After the leather seal is softened, it can be installed with good leakproof effect. If the oil is not immersed in advance, the machine will start to heat up due to dry friction, causing the contact surface of the leather seal to deteriorate. (3) Cork mats. Sometimes gaskets for engine valve housings are made of cork, but this material is easily broken and is not easy to carry. If it is soaked in clean water for a while before installation, it can become flexible and durable. 5. The skeletal type oil seal of the skeletal type has a smaller inner diameter than the outer diameter of the shaft due to the inner diameter of the skeletal oil seal, and most of the shafts have splines. The machine operators generally feel that the skeletal type oil seal is not easy to install, and the operation may be careless. The lip seal is damaged and the seal loses its sealing performance. Now introduce a good way to install skeleton type oil seal: take a piece of plastic film about 0.10mm~0.15mm thick, cut it into a rectangle, the length is 1.5 times the length of the shaft head installed skeleton type oil seal, the width of the shaft head outer diameter of 5 Times, roll the film flatly on the shaft head, wrap all the shoulders and splines on the shaft head; apply a little oil on the oil seal, and pinch the wrapped film with one hand to prevent the film from wrinkling or sliding. The other hand holds the skeleton oil seal on the film of the shaft head and slowly pushes it sideways. When the skeleton oil seal crosses over the shoulders and splines, the plastic film can be gently pulled out. 6. The main shaft of a single-cylinder diesel engine fitted with a single-cylinder diesel engine main shaft has a slightly larger outer diameter, which makes installation difficult. At this time, if the conventional method is forced to install, the main bearing bush will be damaged. Here's a safe and easy way. (1) Scratch two equal lines of equal width to the groove on the back of the round wire of the main shaft with the scrap saw blade. (2) Heat the body seat hole or the main bearing seat hole with oxygen-acetylene flame for 5 minutes to 10 minutes, or wrap the main bearing tile in a plastic bag and place it in a freezer at -30°C to -15°C or outdoor environment The cold set for 5min ~ 10min (summer or winter can be flexible heating or freezing time). (3) Take out the main bearing bush, mark it with the positioning pin at the machine body seat hole, use a wooden block to gently knock the main bearing bush into the seat hole, and then use the puller to install the main bearing bush in place. 7. Installation of High-Pressure Fuel Pipes When installing diesel high-pressure fuel pipes, if both ends of the high-pressure fuel pipe are tightened at the same time, it is very easy for the dirt attached at the joints at both ends to enter the nozzle. In order to avoid the above problems, the operator should install it according to the following method: First, tighten the end of the connection between the high-pressure fuel pipe and the oil pump; then, crank the crankshaft several times, and then discharge the diesel oil after the high pressure oil pipe and the nozzle joint flow out. Tighten oil tube and nozzle.

With the improvement of people's living standards, people pay more and more attention to the importance of physical health. More and more people will use their spare time to exercise, run, ride, climb mountains and so on.
But then comes the safety of sports. A little too much force or improper operation will cause injury. It was originally for the sake of health, but it was only a few days after exercise, which is a bit more than worth the loss.
Nowadays, more and more people begin to pay attention to their health. Running has become the first choice of most people because of its relatively low technical threshold. With the rise of running craze, a variety of equipment has also quietly jumped into the sight of runners, from professional running shoes, sweat-absorbing clothes and pants, wearable electronic devices, and shin and patella band and other protective devices. Running is often prone to sprains, falls and other accidents. Choosing a knee pad that can protect the body is very important.
For runners, there are also several common injuries, such as knee pain, iliotibial tract syndrome, foot blister, sprain wait. How did you solve or avoid the pain problem?
Knee pads and waist support are very good for sports injuries&protective equipment
