In recent years, the well-known Chinese company, Gelton Transmission Co., Ltd., which is engaged in the development and research of automotive transmissions, has organized research staff of postdoctoral workstations in enterprises to strive for breakthroughs in the thermal control of automotive engines. Through digestion and absorption of advanced foreign technologies, after two hundred trials in two years, Gelton of Jiangsu successfully developed a high-tech product that has significant energy-saving and emission-reduction effects—a temperature-controlled electronic fan clutch for automobiles.
The product adopts the principle of constant temperature and variable speed. Through flexible and intelligent design, the engine fan enters the state of electromagnetic automatic constant temperature and variable frequency intelligent regulation, thereby stabilizing the improvement of engine power, greatly reducing thermal energy emissions, and effectively saving energy. The testing and selection of the equipments of the national auto parts authoritative department to put Shanghai Shenwo, Guilin Daewoo, Chongqing Hengtong and Jinlong, and other equipment for China’s passenger cars, trucks and engineering loading vehicles have shown that their energy saving and emission reduction efficiency is 5% to 10%. Performance reached the international advanced level of similar products. Since the advent of this new energy-saving product, it has attracted the attention of domestic automobile and engine manufacturers. They have all gone to Grelton to discuss joint development and product support issues.
The core technology of the temperature-controlled electromagnetic fan clutch lies in the intelligent control of the automobile engine cooling system and the automatic conversion of the fan cooling system. In China, high-speed engines are often cooled by fans that are running at a fixed speed. Under normal circumstances, the engine fan consumes more than 10 kilowatts of heat and consumes more than 10% of the engine's power. Through the intelligent control of the temperature-controlled clutch, the fan's operating speed can be automatically converted as the engine temperature changes, so that the engine always maintains an optimum temperature control state of about 90°C during high-speed operation.
The installation of a temperature-controlled clutch on the front of the engine fan of a car is to install a high-frequency “air conditioner†for the engine so that the engine can be operated at an optimally constant temperature and circulate, ensuring that the fuel is fully burned, and the engine is controlled and reduced in a balanced manner. Heat dissipation and exhaust emissions greatly increase the operating efficiency of power. Since the engine's operation process is in a constant temperature state, the operating frequency of the fan is greatly reduced, the friction coefficient between the fan and the engine is reduced, the noise is reduced, and the overall service life of the engine is prolonged. According to estimates by experts, a 40-seat bus is running at 1,000 kilometers per day. The fuel consumption per 100 kilometers is 30 liters. The oil price is 6 yuan per liter. The annual operation is 360 days. The fuel saving rate is calculated at 5%. DaJing saves 32,000 yuan in fuel for the whole year; the fuel saving rate is calculated according to 10%, and the annual fuel saving amount reaches more than 60,000 yuan. If temperature-controlled clutches are used in heavy-duty trucks and engineering trucks, the annual fuel savings per vehicle is around 100,000 yuan.
Ferrules are used with Hydraulic Hose and hose fittings to make hose assemblies using Crimping Machine.The ends of the steel bars are processed into straight threads by rolling technology, and the two steel bars are connected to each other with the corresponding connecting sleeve.Once crimped, hose connector have permanently adhered to hoses.Steel bar stripping and rolling straight thread connection is a new type of steel connection sleeve technology. Its structural principle is to strip off a part of the longitudinal and transverse ribs at the ends of the steel bars to be connected by cutting, and then directly roll them into ordinary straight After threading, connect them with a special straight threaded steel connecting sleeve to form a steel connection.,Hydraulic Ferrule is one of hose fittings include non skive ferrules,skive ferrules.choose different Crimping Ferrules according to Rubber hose type.
