Several major points of attention when using the tire changer

The tires transmit the driving force, braking force and side force of the car. At the same time, it is necessary to digest, absorb and alleviate the vibration and impact from the ground to ensure the safety and comfort of the car. Therefore, the quality of tires cannot be relaxed all at once. Therefore, the repair and replacement of tires becomes a more frequent job in tire shops. Tire changer-as a special tool for tire repair and replacement, it plays a key role in the entire process. However, it is more expensive, and it is necessary to be careful about the application and maintenance of the tires——

Tips for use: The tire changer is an indispensable machine and equipment in the tire shop. In the case of using the tire changer, there will be some methods to facilitate your application:

1. For tires with good but soft and thin vulcanized rubber on the top of the tire: When using the wind shovel of the tyre changer to shovel the tire deviation, slightly lift the wind shovel to operate the pedal, and at the same time push the tire inward to confirm the shovel Touch the tyre mouth, and then lean it with your legs or hands to prevent the tyre from returning, and then step on the manipulating foot pedal. At this time, it is easier to shovel the tyre off.

2. For the long-time tires of super sports cars: the tires are exposed to the internal standard pressure for a long time, and the heat caused by the friction between the tires and the road surface causes the tires to adhere to the rigid ring. When the wind shovel is difficult to shovel, you can first dissolve the detergent in the water, and use a small brush to brush more water solution on the bead and rigid ring. After the aqueous solution penetrates into the gap between the bead and rigid ring, use the tire changer to remove the tire. .

3. For tires with hard tire openings: It is best to use spring steel sheets for cars when picking up tires, and it is very easy to make an extended crowbar to pry the tire opening to the bird's head. When putting on the tire, use both hands to press the tire belly, 200mm up and down. When the tire opening is at the tightest point, use your left elbow to press the tire belly strongly. At the same time, take the opportunity with your right hand and push the tire clockwise to avoid the motor and triangle. With deviation, the motor can be maintained at the same time.

Tire changer maintenance:
1. The roulette should be kept clean, and the application should always be cleaned with car gasoline and wiped with lubricating grease every week.
2. Carry out cleaning and moisturizing the friction parts of regular fitness exercises.
3. It is necessary to check the air filter element and the pneumatic triplet frequently, and immediately drain the condensed water in the filter element sedimentation cup and add the grease in the pneumatic triplet to maintain the cylinder.
4. Frequently check the tightness of the transmission belt in the box and carry out adjustments.

Analysis and removal of common problems of tire changer

1. After stepping on the power switch of the roulette motor, the roulette produces an inter-turn condition.
When the tyre changer wheel produces an inter-turn condition, you should immediately release the button switch to stop the motor to prevent damage to the motor. The cause of the inter-turn may be:
(1) The SPZ narrow V-belt in the box is too loose to transmit the output power reasonably and cause slippage. Adjust the connecting nut of the motor connection and the reducer to restore the transmission belt to normal tightness.
(2) The equipment is not properly used according to the specific instructions of actual operation. As a result, the load is too large, and the actual operation should be carried out according to the actual operation specific guidance.

2. The clamping force of the cylinder of the tire changer is not enough, and the wheel hub causes slippage or movement.
Slippage or movement of the rotating circle will damage the hub. Therefore it is definitely not allowed.
The reasons for the slipping movement may be:
(1) The standard air pressure of the pneumatic valve is too low. The standard air pressure should be maintained at 0.6-1.0 MPa during all normal operations. Check the working pressure of the pneumatic valve to adjust it to 0.8 MPa.
(2) The steam leakage at the cylinder pressure regulating valve, regulator and air pipe joints is relatively serious, resulting in a decrease in the working pressure of the standard air pressure during work. Check for leaks.

3. The cross arm and the trailing arm cannot be accurately positioned: check whether the camshaft and the camshaft are properly installed in the clamping organization. If it is appropriate but still cannot be accurately positioned, the trailing arm that touches the camshaft can be adjusted for precise positioning adjustment The screw and the horizontally touching the camshaft precisely locate the screw position.

4. It is not possible to reasonably make the tire boss slip off the wheel from the hub wheel.
(1) Check whether the rotary joystick is adjusted properly;
(2) The steam leakage of the detached cylinder is serious, and the working pressure of the spade is not enough;
(3) The standard air pressure of the pneumatic valve is not enough to cause the cylinder pressure to drop.

The tyre changer is a good assistant to the tire person. In daily application and maintenance, the tire person must be both technically professional and cautious. I look forward to the operation guide prepared by Xiaobang today to assist everyone. Naturally, if the knights also have problems, they can summon Xiaobang anytime and anywhere. You only have to post in the community, and Xiaobang will give you the most immediate and comprehensive explanation.
