The necessary weapon of tire shop — tire changer
Tire stripper is also called tire stripper, tire stripper. It is a kind of automobile maintenance equipment that can assist in the disassembly and installation of automobile tires during automobile maintenance, which makes the disassembly of tires more convenient and smooth in the process of automobile maintenance
[by power type]
Pneumatic tire remover, hydraulic tire remover.
[by type of use]
Tire removers for motorcycles, minicars, trucks and engineering vehicles
[structure]
1. Main machine workbench: the tire is mainly removed on this platform, which mainly plays the role of placing the tire and rotating.
2. Separation arm: on the side of the tire remover, it is mainly used to separate the tire from the rim, so that the tire can be removed smoothly.
3. Inflation and deflation device: it is mainly used to let off the air of the tire, which is conducive to inflation or disassembly. In addition, there is a barometer to measure the air pressure. General tires are at about 2.2 atmospheres. 2 MPa.
4. Foot pedal: there are three foot pedal switches under the tire remover, which are respectively used to rotate the switch clockwise and counterclockwise, separate and tighten the switch, and separate the rim and tire switch.
5. Lubricant: conducive to the disassembly and assembly of the tire, reduce the damage in the process of disassembly and assembly of the tire, so that the disassembly and assembly of the tire can be completed better.
6. Compressed air connection
[operation precautions]
1. The power supply of the tire engine must be in normal state, and the power supply must be in off position under non working state. The internal air pressure of the tire engine must be at normal pressure, and the air duct shall not be connected under non working state.
2. Before changing the tire, check the tire frame for deformation, and check the air nozzle for air leakage and cracks.
3. Open the air nozzle to release the tire pressure, put the tire in the middle of the compression arm, and operate the compression arm to separate both sides of the tire from the wheel frame.
4. Operate each switch to remove the reverse tire.
5. When the new tire is installed, the tire Peugeot is upward. Operate each switch to install the tire.
6. After assembly, the switches are placed in the off position.
[purchase guide for tire dismounting machine]
(1) Pay attention to the rated power of the motor. The higher the power is, the stronger the working stability is. The power of the motor is generally more than 1000W. In order to reduce the cost, some manufacturers use about 800W motor, and the working stability is much worse. Investors can open the side cover to check the rated power of the motor when purchasing. The motor should work with low noise and no obvious vibration
(2) When running, the noise should be low, and there is no obvious vibration when the load is on. The reducer is the reduction device for the power transmission of the tire dismounting machine. Because the speed of the AC motor is generally above 100r / min, it must be reduced to about 100r / min through the reducer before it can work normally. The reducer is usually made of special materials and alloy materials, and the noise must be low when driving, Good balance performance. Some small tire dismounting machine manufacturers use low-quality hard alloy casting reducer, which makes a lot of noise when working, so pay more attention when loading
(3) The quality of tire dismounting head is also directly related to the quality of tire dismounting. At present, there are two kinds of tire dismounting heads on the market: one is made of high-quality rigid casting, which is more expensive; the other is made of rubber, which is relatively cheap, which is easier to identify when purchasing. The market price of a high-quality steel cast tire dismounting head is about 800 yuan, and the ordinary one is also 300 yuan. Its arc design curve is more scientific, It is easy to deform after many years of use, and it is very smooth when loading and unloading tires, and it can protect the rim and tires from damage. The inferior tire dismounting head is not the same, the appearance is rough, the arc curve design is unreasonable, the loading and unloading tires are not smooth, and it is easy to deform after many times of use, and it is easy to scratch the tires and rims. Therefore, it is necessary to load and unload tires on site to verify the advantages and disadvantages of the dismounting head
(4) At present, the technical content of some automobile maintenance equipment in the market is not high, and there are many unqualified processing plants. The equipment that can be produced is sold to the market. This kind of equipment can not be purchased, and the quality is not guaranteed, and the repair rate is high
