st of all, tell us about the basic structure of control cable and performance parameters. Pan said the flexible shaft control cable is used to achieve indirectly (Remote remote control) transfer mechanical force or displacement control mechanism. With the traditional lever control mechanism compared with the arrangement of flexible, easy to install and maintain low cost is widely used in construction machinery, vehicle engineering and shipbuilding industries.
Control cable car project in accordance with its cable core nature of the Movement and force can be divided into push cable, cable and flexible shaft of three. Which push the structure of the more complex the following cable to push cable, for example, introduced the basic composition and control of cable performance parameters. Control cable usually couplings, cable and connections of three parts. Coupling that joins the main role of the controller and the cable core, usually by the nut, rod, tube, sleeve, dust cover and seal components. Among them, couplings and connections for the structure type can be connected according to the specific needs of select design, but the movement must be guaranteed to meet the schedule, connection strength and stiffness. Cable is a cable core and the casing composed of two parts, with the gap with its. Cable core from the metallic cable core and covered with friction material composition; casing by a liner, casing and the casing of metal layer composed of the outer cover. According to the structural characteristics of metal casing, casing pipe can be divided into single-wire [link widoczny dla zalogowanych], double twisted wire tube and pipe and so on. Among them, twisting tube than the traditional single wire tube significantly improved the quality.
Again introduce the spark plug. It is different in any engine speed and engine load, at the right time can provide enough voltage to spark Plug to produce enough to ignite the spark of the mixture within the cylinder [link widoczny dla zalogowanych], so the best engine combustion efficiency. The basic unit ignition system includes power supply (battery), ignition trigger device, the ignition timing control device, high voltage generator (high voltage ring), high voltage distribution system (Distributors), high voltage wires and spark Plug. Modern devices have already been changed by the spark advance computer-controlled engine management computer to collect engine speed, intake manifold pressure or air flow, throttle position, battery voltage [link widoczny dla zalogowanych], temperature, detonation and other signals, calculate the optimum ignition timing advance angle, and then send the ignition signal to control ignition timing purposes.
Spark ignition engine to have to rely on spark ignition, while the spark is generated by spark Plug. Spark Plug Thread locked by the engine combustion chamber at the top of pay, which is in the cylinder head and into the valve between the spark plug in the head with a central electrode and the grounding electrode, grounding electrode is threaded into the L-shaped section extending from , and the maintenance of the central electrode gap of 0.7 to 0.9mm, while with the high-voltage spark plug wire to connect the tail. When the high voltage wire to high voltage sent to the spark plug, resulting in a spark plug of the two great potential difference between the electrodes, resulting in two poles can not be conductive gap between the original air a conductor, current will flow with ions (Ionizing Streamers) by way of one electrode to another electrode spread, resulting in arc (Electric Arc) to ignite the engine is in the oil and gas.
If you still feel difficult to understand, can go to observe the stove or discharge ignition lighters, spark plug ignition is very similar to the way in which they are. In addition to the size of spark Plug have all kinds of different things, there will be the same size of spark plug heat value (Heat Rating) different. Spark plug heat value of large parts of the electrode insulation and longer for lower engine operating temperature; while the spark plug heat value smal
