Problems solved by technology

After the transmission dynamic balance test, the gas inside the tire is directly discharged into the atmosphere, and the large number of test tires will inevitably cause waste of energy and increase the production cost of the company.
At present, energy saving and consumption reduction advocated by the society is a direction for the sustainable development of production-oriented enterprises. Obviously, the improved dynamic balance detection method is unreasonable and needs to be changed.

Embodiment 1

[0029] Example 1 A device for recovering and reusing compressed gas from tires of a dynamic balancing machine

[0030] A tire dynamic balance testing machine in the prior art includes an air compressor 1 for supplying compressed air and an air delivery pipe 8. One end of the air delivery pipe 8 is communicated with the air compressor 1, and the other end is used to communicate with the tire to be tested. 5 connectivity settings;

[0031] The air compressor is provided with an inflation valve 2 to control the inflation work, and the inflation valve 2 is opened, and the compressed gas in the air compressor is transported to the inside of the tire 5 through the air pipeline;

[0032] The gas delivery pipe is provided with an exhaust valve 3, so that after the detection work is completed, the exhaust valve 3 can discharge the compressed gas in the tire 2 to be tested to the atmosphere in time to obtain the initial finished tire.

[0033] Due to such repeated inflation and deflati...

Embodiment 2

[0051] Embodiment 2 Method for recovering and reusing compressed gas from dynamic balancing machine tires

[0052] see figure 1 and figure 2 , using the device described in Embodiment 1, a device for recovering and reusing the compressed gas of a dynamic balancing machine tire, including an air compressor for providing compressed air and an air delivery pipe, one end of the air delivery pipe is communicated with the air compressor, The other end is used to communicate with the tire to be tested; wherein, the device also includes at least two air storage tanks, and the two air storage tanks communicate with the air pipeline through the first pneumatic solenoid valve and the second pneumatic solenoid valve respectively setting; one of the air storage tanks is arranged at a station close to the tire to be tested, and the other air storage tank is arranged at a station near the air compressor; the device also includes a controller, the controller is connected with the inflation ...

Embodiment 3

[0059] Example 3 Benefit cost calculation

[0060] Calculated based on the tire size data of 12.00R20, the volume of the calculated tire inner cavity (after the tire is inflated, the tire is regarded as the volume of the outer diameter cylinder of the tire minus the volume of the outer diameter cylinder of the rim) is about 0.2 cubic meters; after adding this system , the detection tire is pre-inflated to 0.35MPa first, and then inflated by the air source of the air compressor to the detection pressure of 0.65MPa, regardless of the influence of temperature changes. (3.5+1)*0.2=0.9Nm³ standard pressure gas. The following calculates the cost of compressing each standard square of gas:

[0061] Recognized value in the air compression industry (that is, the value to be provided when the air compressor is purchased): When it is required to produce 0.6MPa compressed air, a 1HP (horsepower) air compressor produces 0.1188 cubic meters (inhalation state) of compressed air per minute. ...

Abstract

The invention relates to a method for recovering and reusing the compressed gas of tires of a dynamic balancing machine. The method includes the following steps: Step 1) Recovery stage: first balance the high-pressure gas tank, and then balance the low-pressure gas tank; the first high-pressure gas storage tank of the recovery device The first disc valve is opened, and the gas is first discharged into the high-pressure air tank. After the tire internal pressure is balanced with the tank body pressure, the first pneumatic solenoid valve is closed; the second disc valve is opened, and the inner cavity of the tire communicates with the low-pressure air tank, and the air pressure is balanced again. , the second pneumatic solenoid valve is closed; Step 2) Inflation stage: first use the low-pressure air tank to inflate the tire, and then use the high-pressure air tank to inflate the tire; the second pneumatic solenoid valve is opened, and the low-pressure air tank and the inner cavity of the tire start to balance the pressure. The second pneumatic solenoid valve is closed, the first pneumatic solenoid valve is opened, the high-pressure gas tank communicates with the inner cavity of the tire, and the air pressure of both sides begins to balance. After the internal pressure of the tire and the tank body air pressure are balanced, the first pneumatic solenoid valve is closed. The invention is safe and saves cost.

Description

technical field [0001] The invention relates to tire production equipment, in particular to a method for recovering and reusing tire compressed gas of a dynamic balancing machine. Background technique [0002] Tires are the second largest consumer goods after fuel in the use of automobiles, and their dynamic balance performance is directly related to the performance of automobiles. Due to manufacturing problems, the mass distribution of each part of the car wheel composed of tires and hubs cannot be very uniform. When the car wheel rotates at high speed, it will form a dynamic unbalanced state, causing the wheel to vibrate during driving. The phenomenon of steering wheel vibration, in order to avoid this phenomenon or this phenomenon that has already occurred, it is necessary to perform a dynamic balance test on the tires through a tire dynamic balancing machine. [0003] When a tire is tested by a dynamic balance testing machine, it needs to be inflated to a certain pressu...
