Maintenance skills of warm air blower

After a period of driving, there is a layer of foreign body and dust on the surface of the radiator. If it is not cleaned, it will affect the heat dissipation. After a long time running, the blower motor should be maintained and replaced by the motor. This operation must be judged and maintained by the professional, and the motor can not be dismantled privately. This can cause the short circuit and the motor not to turn, the light person burns insurance, and it causes the burning line and the fire seriously. The motor ventilation pipe can not be removed, and it will easily cause the motor to overheat and burn out after being removed. The variable speed resistor can make the motor change gears. If the one or two gears are used for a long time, it will easily cause the resistance to burn and affect the normal use. The operating system is used for a long time, manipulating the drawing wire is easy to be aged and deformed, so that the manipulating is not flexible or in place, and do not move hard and avoid the damage of the parts. It is found that the problem should be judged at the maintenance station and repaired and replaced according to the specific conditions. The ventilation pipe is the No. 1 and No. 2 hose of the warm air blower. Because of the long time used in high temperature, it is very easy to get aging and crack. It should be replaced in time so as to avoid water leakage and cause the temperature of water to be too high and the cylinder head of the engine can be deformed. The hose used for the rubber hose is equipped with charcoal hose, and the poor quality hose is not resistant to corrosion.
The device should pay attention to these points in the use: when the winter temperature is below 0 C, the front windshield will have a layer of ice and frost. Starting the engine, when the water temperature is above 40 degrees centigrade, the control is placed in the defrosting position in the position of the indicator, and circulates in the position of the indoor cycle, and the blower motor is opened to the three gear position. At this time the motor speed is highest and the motor is running for 3 – 5 minutes. Then the gear can be placed in the one or two gear position according to the defrosting condition. During this period, drivers are advised not to leave the cab. If the motor is not turned, the motor should be put back to the closed position immediately, so as to avoid burning resistance. When the outside temperature is low and the driver is multiplied for a lot of staff, the glass will have frost. It can be put in the defrosting position and the position of the outdoor cycle. The motor can be placed in one or two gear positions so that the frost can be removed. When there is no wind blown sand and dust outside, the cycle can be put outside to make the cab air clean. If there is wind sand and dust or when the weather is too cold, put the cycle into the indoor circulation to avoid wind sand and dust entering the cab.
