The transmission control composition of CNC flame cutting machine is mainly divided into three categories according to the selected accessories. The three types of methods all occupy a certain market share in the CNC cutting machine on the domestic market, namely ball screw drive, rack drive and belt drive. . Three kinds of transmission methods have their own application characteristics: First, the ball screw drive The so-called ball screw, is composed of the screw, nut and ball. Its function is to convert rotational motion into linear motion. Since the bearing rolling action becomes a small frictional resistance after sliding, the ball screw is widely used in various industrial equipment and precision instruments. The transmission method with the highest mechanical transmission accuracy is mainly used for the transmission of high-precision numerical control equipment such as CNC punch press and numerical control laser cutting machine. However, the combination of plasma cutting, ball screw drive applications is relatively small, the main reason is that the plasma cutting precision compared to laser cutting, punch processing, it is also a preliminary processing equipment, similar to the barrel principle, improve the transmission accuracy alone, The improvement of the final cutting accuracy is relatively limited, and it can be understood that the precision of the ball screw drive cannot be fully utilized. On the other hand, the ball screw drive transformation of the numerical control equipment is performed. In order to achieve the precision effect, the corresponding drive motor is required. And for the high-speed adjustment gear reducer, comprehensive analysis of equipment procurement costs will increase significantly. Currently applied to CNC cutting equipment, ball screws are mostly 25MM shafts. Shafts of this specification will vibrate at high speeds, negatively affecting the cutting accuracy and the overall operation or phase. Second, rack drive rack transmission is through the precision rack control transmission accuracy, gear driven equipment running a transmission method. Rack drive basically has no influence on the deformation and shrinkage resistance. At the same time, depending on the condition of different racks, the width of the drive sticking surface can reach wider, the occlusal surface of the internal teeth is more, and the performance on the transmission accuracy is also more stable. At present, rack drives are mostly used in industrial-grade CNC cutting machines. The main reason is that the stability of cutting equipment is guaranteed during long-term processing and use. At the same time, in order to apply to the requirements of rapid cutting processing, plasma cutting equipment can be used to drive motors with different power according to the requirements of users. Third, the belt drive The so-called belt drive is driven by the belt to produce continuous rotary motion, the force from one transmission wheel to another. The belt drive has the characteristics of small anti-deformation and shrinkage, wide width of the sticking surface of the transmission, more occlusal surfaces of the inner teeth, faster speed, and less negative gravity, etc., and multi-application of rapid processing equipment. At present, the Y-axis and X-axis transmission methods adopted by some plasma cutting equipment are the belt transmission methods, especially in some rapid plasma cutting equipment applications, due to the characteristics of the belt transmission itself, it will be more fully achieved during the rapid transmission process. The embodiment. However, taking into account the plastic material of the belt, there is bound to be an aging problem in the long-term use of the process, and its transmission characteristics will also be greatly reduced, data analysis, the use of belt drive plasma cutting, the cutting accuracy of its equipment in the use of 1-2 years will be reduced by 30 about.

The background and signification of research this waste tire pyrolysis program

As tire has been used for all other industry widely, they are playing an important role in the development of our economy, but waste tire did not easy to broken after being used and it becomes a big pollution for our environment .Therefore it is urgent to process those waste material without pollution.

In addition ,as the fastest development of world economy ,the shortage of petroleum will be urgent more and more , even the expert had stated that it will have no petroleum recover in earth after 15years later, so searching the new resource becomes an issue which is concerned by all the countries of the world.  




1.Working process Of waste tire Pyrolysis Plant:

First, the raw materials are put into the reactor, and then seal the feeding in door, later start the machine and the reactor will be rotating and heated by coal, natural gas, wood or electricity. When the temperature reaches the degree of 250 to 280, we will get the crude oil, the oil steam will be continuous produced until the temperature reaches 350-460 C; oil steam will flow through oil gas separator, light component will enter the condensers and meanwhile the heavy oil will be discharged automatically into in heavy oil tank. The liquefied part will be condensed as crude oil, and the part which cannot be liquefied will be transferred by the water seal back to the burning chamber to be reused as heating material.
