subject: Note The Use Of Control Cable [print this page] As various types of electrical control cable, instrumentation and automation equipment between the cable used by cable. It plays a variety of power transmission control signal effect, widely used in industrial and mining enterprises, transportation, defense and scientific research sectors, the role of the safety of power supply even more than the power cable. Particularly in the railway, national defense, scientific research departments in control and signal system cables, and its importance is obvious.
Control cable is divided into two major rubber and plastic insulation products. After 70 years, with the development of plastics industry and product performance and manufacturing processes on their own merits, plastic insulated control cable in the world have achieved rapid development, not only the proportion increases every year, and the penetration rate is greatly improved, has developed into a control cable The main varieties. On the contrary, the use of rubber insulated control cable range decreased, the key used for special purposes and requirements of the laying of soft places.
Cable alignment of controls to block changes in the layout, it is to accept them at the end of the internal control cable. surrounded by an external cable clamps securing the internal cable. On the other hand the holder to accept the end of the lever bar. Around the holder to sell part of the slider is movable between locking and unlocking limit to determine the place where the two flanges formed on the outer circumference of the holder. Slide the holder of a flexible material such as rubber and the handle to the adoption by the end of the lever side of the circumference of the outbreak. When the slider moved from the closed position to lock the control rod position at the end of the stick holders and owners at the end of the internal cable to a close, so relaxing is the relative position of the cable and remove the internal cable and the lever may be adjusted by simple touch..
In this Agreement the control cable when the gear shift is in the P (parking), and the engine off, lock this lever can not be moved to another location changes. Therefore, we must always shift lever in P position of the engine start-up operations. This safety feature, widely used in automotive automatic transmission equipped vehicles. When you turn the ignition key in the cylinder, the control cable and pulled the lever lock downgrade. If the bulk or cable tension, cable tension adjustment is necessary. Typically, an external cable is an important part of the thread by turning nuts or mobile support in the aspects affecting the safety of the cable tension adjustment collar. Attach the impact of such a voltage regulator control cable is cumbersome and time consuming. Furthermore, after multiple adjustment nuts are becoming old and increasingly difficult to apply to the regulation of voltage control cable torque. In addition, the application for adjustment of the force of cable regulation, it is difficult to compensate for weak external and internal cable through the cable.
While the present invention has been disclosed in terms of the preferred embodiment in order to facilitate better understanding thereof, it should be appreciated that the invention can be embodied in various ways without departing from the principle of the invention. Therefore, the invention should be understood to include all possible embodiments and modifications to the shown embodiments which can be embodied without departing from the principle of the invention as set forth in the appended claims.
The key part of the spark plug insulator, does not work if the insulator, high voltage will "Chao Xiaolu" in lieu of poles into the ground, causing no sparks. Spark plug insulators must have good mechanical properties and resistance to high voltage, high-temperature impact resistance, chemical corrosion ability, more than ordinary spark plugs used to made of alumina-based ceramics. Spark plug size is uniform throughout the world, any car can be generic, but different types of gasoline engines, so will take a spark plug there are two basic types, type and heat and cold. Type and heat and cold are relative terms, it reflects the thermal characteristics of spark plug performance. Spark plugs have the right temperature to work well without coke to work properly.
Proven spark plug insulator to maintain the temperature at 500-600 , the fall of the oil droplets insulator will not immediately burn off the coke formed, higher than the temperature of early burning, lower than the temperature coke. At different engine temperatures will be different, the designer on the use of insulator length skirt to resolve this contradiction. Some short skirt heated area small, fast heat dissipation, so skirt the temperature lower, is called cold type spark plug for high-speed high-power engine with high compression ratio; some slender skirt heated area, heat slowly, so skirt temperature is higher, known as thermal-type spark plug for the low compression ratio in the low-speed low-power engine. What spark plug in his car, according to the manufacturer's requirements models to choose from, not a spark plug are applicable.
