Recently, Chongqing No. 1065# Electrolytic Cell Co., Ltd. (hereinafter referred to as "Qineng Company") has successfully adopted the electroslag welding technology for full-section welding of cathode steel rods. This technology is the first application in the domestic electrolytic aluminum industry. After the start of the company's 1065# electrolyzer, the cathode pressure drop dropped below 250mV. Compared with the traditional manual welding, the cathode pressure drop was reduced by about 30mV, the energy saving per ton of aluminum was 100kwh, the cathode pressure drop reached a record low, and the welding time was artificial. Welding was shortened to 2 days in 4 days, which greatly reduced the strength of manual welding work.
As electrolytic aluminum plant electrolysis plant is a high magnetic field environment, the field is affected by the strong magnetic field, the traditional technology has been to use artificial welding steel sheet to connect steel heads, there will be defects such as false welding, false welding, and the working space is very narrow, Welding workers have high labor intensity, low efficiency, and affect the welding quality of cathode steel rods; electroslag welding technology uses electric current to discharge resistance heat through the slag pool, the slag pool is sufficiently overheated, and the consumable electrode tip is immersed in the superheated slag pool to absorb heat and form. The droplets, the droplets dripping through the slag pool, drip into the molten metal pool, the metal in the molten pool and the cathode steel rod as one, to achieve the role of welding, electrolytic cell overhaul welding technology revolutionary progress.
Car engines are designed around sealed, resilient metal cylinders. Most modern vehicles have between four and eight cylinders, though some vehicles can have as many as sixteen! The cylinders are made to open and close at precisely the correct time to bring in fuel to combine with the spark for burning internally, and to release the exhaust gases produced. While there are several components on an engine, we`ve compiled a list of the most essential car engine parts and their functions, that power your vehicle. Refer to the diagram to locate where they reside on your engine.
Engine valve – This is the very core of the engine. Often made of aluminum or iron, it has several holes to contain the cylinders as well as provide water and oil flow paths to cool and lubricate the engine. Oil paths are narrower than the water flow paths. The engine block also houses the pistons, crankshaft, camshaft, and between four and twelve cylinders-depending on the vehicle, in a line, also known as inline, flat or in the shape of a V.
Pistons – Are a cylindrical apparatus with a flat surface on top. The role of the piston is to transfer energy created from combustion to the crankshaft to propel the vehicle. Pistons travel up and down within the cylinder twice during each rotation of the crankshaft. Pistons on engines that rotate at 1250 RPM, will travel up and down 2500 times per minute. Inside the piston, lie piston rings that are made to help create compression and reduce the friction from the constant rubbing of the cylinder.
Timing Belt/Chain – The camshaft and crankshafts are synchronized to ensure the precise timing in order for the engine to run properly. The belt is made of a heavy-duty rubber with cogs to grasp the pulleys from the camshaft and crankshaft. The chain, similar to your bicycle chain wraps around pulleys with teeth.
