Sprinkler tire selection principle:
The same brand, model and size of tyres manufactured by the same manufacturer shall be installed on the sprinkler. If the above requirements cannot be met, at least the tyres on the same shaft must achieve the above requirements. It is forbidden to use a combination of bias tires and radial tires. When replacing tires, the requirements of the sprinkler 's instructions, including dimensions and specifications, must be met.
Precautions for use of sprinkler tires:
Tyre pressure should be reasonably inflated in accordance with the requirements of the vehicle's operating instructions. The two coaxial tire pressures should be the same. If abnormal tire wear and cuts are found, identify the cause of the problem as much as possible. In the case of normal pressure, if there is abnormal wear, the main reason may be the front wheel positioning and technical failure of the special structure. In addition, poor balance of wheel movement, overload, etc. will also lead to abnormal tire wear.
If the depth of the tread pattern does not wear to the limit, replace it. In general roads, we must ensure that the depth of the pattern is greater than 1.6 mm. If on the highway, I must guarantee that it is 2.4 mm or more. If it is lower than this standard, we must replace it in time. If there are foreign objects in the tire tread, it may be damaged. Otherwise, it may harm the inside of the tire during long-term driving. Replace the tires in pairs.
Which methods can effectively prolong tire life
Improve the service life of sprinkler trucks Some methods: Smooth start, no overloading; Speed ​​control, smooth up and downhill; Economic speed, avoid sudden braking, sharp turn; Avoid obstacles, choose roads; Avoid tire pollution (such as pollution (Timely cleaning); to avoid tire idling when trapped; cold days (cold winter) antifreeze measures; hot summer, to control the temperature of the tire.
The temperature of the tire cannot exceed 95 degrees Celsius. At a temperature of 0 degrees Celsius, the temperature of the tire is allowed to rise 95 degrees Celsius. At a temperature of 40 degrees Celsius, the temperature of the tire is only allowed to rise by 55 degrees Celsius. If the tire temperature is 22 degrees Celsius, the service life is 100%, and when it rises to 100 degrees Celsius, the strength of the tire cord is reduced by about 20%. Therefore, in the hot summer season, the temperature rise of the tire must be controlled so that it does not exceed the dangerous line of 95 degrees Celsius.
The air conditioning unit consists of an evaporator and a heater core to heat or cool the air in the operator's cab.
The heater core is heated by the hot water from the engine (engine coolant).
The air delivered by the blower fan and the blower motor is heated through the radiator fin of the heater core.
