According to special margin fan clutch understanding, silicone fan clutch Profile Editor silicone fan clutch, with silicone oil as a medium, the use of high-viscosity silicone oil transfer torque characteristics. Air temperature behind radiators, automatic control of the fan clutch engagement and separation by temperature sensor. Low temperature, the silicone oil does not flow, the clutch fan, fan speed slows down, essentially idle. High temperature, the viscosity of the silicone oil fan clutch, whereby the rotation axis together with the fan and pump, play the role of regulating the temperature of the engine.
Silicone fan clutch works edited silicone fan clutch, bimetal temperature sensing element is a coil spring probes. Course of their work:
(1) When the temperature of the air flowing through the radiator increases, the bimetallic thermal deformation temperature sensor, forcing the valve shaft, the driven plate into the open hole. Driven between the cover plate and the front reservoir flows into the working chamber of the silicone active plate and the driven plate, the clutch engagement, the fan speed increases. Air temperature, the greater the degree of opening into the hole, the faster the fan speed.
(2) When the temperature of the air flowing through the radiator down bimetallic temperature sensor restitution, close the valve into the hole, under the effect of centrifugal force, silicone oil reservoir chamber to return back through the hole from the working chamber, the clutch , fan speed becomes low.
In case any of the following conditions exists, the need to replace silicone fan clutch:
1, the engine overheating
2, silicone oil was leaking from the fan clutch assembly, the fan with little or no resistance in the case of rotating (spinning)
3, oil filled heat sensing plate cover or place the drive shaft through the housing
4, the fan does not rotate the shaft vibration or
5, bearing there shrill noise
Note: When installing a pump, you should check whether you need to replace silicon oil fan clutch
According to Yu Fan Clutch special note, silicone fan clutch function and design edit all silicone fan clutch is designed to the highest quality standards and manufacturing, and provides approximate or exceed original specifications performance. Reliable quality, advanced production equipment and testing equipment, high manufacturing precision. Temperature sensor, oil, bearing all imported parts, ensure the excellent performance of the product. Covering more than 50 countries and regions.
Temperature silicone fan clutch:
Silicone fan clutch thermostat has a built-in thermal sensor chip for detection of flow through the radiator and air conditioning condenser air temperature. Viscous fan clutch engagement only when needed and provide air circulation. At the time of separation, silicone fan clutch is turned off to reduce horsepower loss and improve fuel economy.
In the clutch engagement time, the standard conditions, silicone fan clutch speed of approximately 75% of the pump rotation. Overloaded and overweight silicone fan clutch is able to pump about 90 percent of the speed of rotation in order to provide additional air circulation.
When the need for cooling, separating and silicone fan clutch 33% speed rotation. Conclude:
When using more efficient engine power, improved fuel economy, less fan noise and prolong the life of the belt and water pump.
Silicone fan clutch overweight and are very similar in all aspects of the original, is designed for driving under the conditions of overweight driving SUV, light trucks, and RVs.
Overweight silicone fan clutch features:
Viscous fan clutch automotive vehicle engine cooling system plays the most important role in automotive silicone fan clutch shaft driven by the pump or fan shaft, according to the coolant temperature control fan speed automatic automotive fan clutch silicone reduce noise and improve fuel - air ratio, maintaining the temperature of the cooling agent is constant.
Overweight silicone fan clutch design:
According to special margin fan clutch is understood that in order to meet the cooling needs of each car, the silicone oil fan clutch must remain exactly the same rpm at operating temperature accuracy requirements. Silicone fan clutch not produce noise, vibration, and other issues at a very high hardness and makes the engine speed is too cold. Since speed is not enough and can not cause the engine to overheat.
Visco Fan Clutch layout editor silicone fan clutch and classification engine in the layout:
Typically, it is installed in the back of a car engine cooler, the temperature of the cooling agent according to control fan speed.
There are more than 320 ordinary silicone clutch varieties, suitable for all kinds of cars, light trucks, ordinary trucks, heavy trucks, buses and luxury buses multiple models.
Electronically controlled clutch has 10 types of silicone oil, widely used in ordinary trucks, heavy trucks, luxury buses.
Silicone oil is divided into two-speed electromagnetic clutch electromagnetic clutch and three-speed electromagnetic clutch for luxury buses and heavy equipment vehicles.
