Electric silicon oil clutch water pump

Abstract

An electronic silicone oil clutch water pump comprises a water pump body, a front cover, an oil storage cover, a shaft coupling bearing and an impeller. The front cover is hermetically connected with the front end part of the water pump body so as to form an inner space which has an oil storage cavity and an engagement cavity for a circulation passage. In addition, a valve plate controlling the circulation of silicone oil between the oil storage cavity and the engagement cavity is arranged between the oil storage cavity and the engagement cavity. Correspondingly, the oil storage cover is provided with an oil regulating hole. The shaft coupling bearing is inserted into the water pump body. The electronic silicone oil clutch water pump is characterized in that the clutch water pump also comprises an electromagnet which can attract the valve plate after being electrified and further control the opening of the oil regulating hole, and a wire bundle which is connected with an electronic control unit. The electromagnet at least comprises an iron core and a coil. The valve plate is elastic and closes the oil regulating hole from the oil storage cavity to the engagement cavity due to the self elasticity in an unstressed status. Compared with the prior art, the electronic silicone oil clutch water pump has the advantages of electronic control on the impeller speed, quick response and accurate control.

Description

technical field [0001] The invention relates to an automobile engine cooling system assembly, in particular to an electronic silicon oil clutch water pump. Background technique [0002] Saving energy is a long-term policy of the country's economic development. At present, the speed control technology of the cooling fan of the automobile engine has matured, but the speed control technology of the impeller of the water pump has just begun. Traditional water pumps are driven by a belt, and the impeller speed is equal to the pulley speed, wasting energy when strong cooling is not required. [0003] At present, some motor-driven water pumps can realize impeller speed control. With reference to the Chinese invention patent application: CN96114781.4, a kind of "Fan Automatic Clutch Automobile Water Pump" (publication number: CN1184884A) is disclosed, which is characterized in that the water pump is equipped with a thermal sensor. When the water temperature in the pump cavity rise...
