Wheeled tires, from the price point of view, account for about 15-20% of the total price of the tractor. The quality of the tires directly affects the driving of the tractor. The proper use and maintenance of tires and the extension of the service life of the tires are of great significance to the use of tractors. First, the cause of tire wear 1. Too low tire internal pressure or overload use will greatly increase the carcass of the stress and deformation, so that the tire and the ground area between the mechanical friction and the carcass of the internal friction increases, causing tire wear and damage. 2, tire pressure is too high. High internal pressure increases the tensile stress on the tire ply, increases the shear stress between the layers, increases the rigidity of the carcass, and reduces the area of ​​the ground, resulting in deterioration of the tire's performance and wear and damage. 3. In the use of a tractor, sharp starts, brakes, and sharp turns will accelerate the wear of the tire, causing collapse of the flower and damage to the bead. 4. Fast and over-high and sharp obstacles can easily cause tires to be cut, blown, and pierced. 5. The tractor runs at a high speed for a long time. According to the characteristics of the tire, with the acceleration of the vehicle speed, the frequency of deformation of the tire increases, causing the temperature of the tire to increase, causing wear and damage. 6. The traction performance of tractors in soft soil is poor, especially in paddy field operations or after rain, when driving on muddy roads or when climbing heavily, it is easy to produce tires with skid and wear. 7. If the tractor starts with a drag or a landslide, it will cause severe friction between the tire and the ground. 8. The front wheel of the front wheel of the tractor is improperly adjusted or the wear of the steering system cooperates to cause the front wheel to produce a shimmy, causing the front tyre surface to wear out. 9. In the process of disassembly and maintenance of the tires, such as assembly and disassembly, carelessness, bruising, injury to the bead and rims, or inclusion of sand, stone and other debris in the inner tire of the inner tire, resulting in tire damage. 10. Improper storage of tractors and tires, exposure to sunlight, and oil eroding, causing corrosion and deterioration of tires. Second, to prevent the method 1, the tire during use, should always check the tire pressure, in accordance with the internal pressure of the tire side of the inflation. 2, the tractor's starting, changing and braking can not be too fierce, try to avoid the starting point of the shift, Mengsong clutch, heavy-duty throttle high-speed start, turn dead and killed the steering wheel, and unnecessary braking and so on. 3. The tractor should slow down when driving on uneven roads and working on stubble, cotton, corn, etc. 4. The speed of the tractor should be mastered according to the actual situation. Try to avoid long-distance high-speed tractor transportation. 5. The tractor can easily slip when working on soft soil or on muddy roads or on heavy-duty climbing. It can be improved by increasing the attached weight of the tractor drive wheel or by hanging the chain or wheel barb on the tire. The wheel's adhesion properties prevent slipping. 6. When the tractor is working in the field, it should use machinery matched with the model. When a car is trapped, it should try to avoid high-speed idling of the wheel in the pit. When the trailer is transported, it must not be overloaded. 7. Correctly maintain the tractor's steering system and maintain the correct front wheel toe value to prevent premature wear of the front wheels. 8. Try to start the tractor without using drag, pull and landslide. 9. When disassembling the tires, they should be carried out on a clean ground. There should be no tools with gaps or sharp corners. When installing, do not put the sand into the direction of the pattern. 10. Do not contaminate tires with oleic acid, alkalis, etc. to prevent corrosion. 11. When it is not working for a long time, the locomotive should be jacked up so that the tire does not bear pressure, but do not let go of air. In addition, tires should be prevented from being exposed to sunlight. 12. Under normal circumstances, after the tire has been used for a certain period of time, the left and right tires should be interchanged to extend the service life of the tire.
Mattress
We are Hospital Electric From China Manufacturer Medical Bed, also known as Hospital Bed Home Care, Hospital Equipment, Nursing Bed, etc., is a hospital bed used by patients when they are hospitalized in the hospital.
There are many classifications of medical beds, and the specific classification methods are as follows: According to the material, it can be divided into ABS medical beds, all stainless steel medical beds, semi-stainless steel medical beds, all steel sprayed medical beds, etc.
According to the function, it can be divided into electric medical beds and manual medical beds. Among them, electric medical beds can be divided into five-function electric medical beds and three-function electric medical beds. Manual medical beds can be divided into double-shake medical beds and single-shake medical beds. Medical beds, flat medical beds.
According to whether it can be moved, it can be divided into a wheeled medical bed and a right-angle medical bed. Among them, electric medical beds are generally movable with wheels.
