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

The present invention solves the problems of the technologies described above the technological scheme that is adopted: a kind of electric silicon oil clutch water pump, comprise water pump body, protecgulum, oil storage cover, Bearing with multiple rows of balls and impeller, this protecgulum and water pump body front end are tightly connected and form the inner space, this inner space has the shoe cream room and the engagement chamber of circulation passage, and at the valve block that is provided with silicone oil circulation between a control shoe cream room and the engagement chamber between shoe cream room and the engagement chamber, accordingly, oil storage cover is provided with the adjusting oilhole, Bearing with multiple rows of balls is arranged in the water pump body, it is characterized in that this clutch water pump also comprises can the described valve block of adhesive after the energising and then the electromagnet opened of regulating and controlling oilhole and the wire harness that is connected with electronic control unit, described electromagnet comprises iron core and coil at least, described valve block has elasticity, be under the no stress, valve block is closed shoe cream room because of self elasticity and is led to the adjusting oilhole that meshes the chamber.
Further, the front end of described Bearing with multiple rows of balls is positioned at the inboard close aforementioned active plate of water pump body and is provided with described oil storage cover, and the space forms described shoe cream room after the aforesaid oil storage cover near before being covered with active plate, and aforesaid active plate and protecgulum form the engagement chamber.
As preferably, described adjusting oilhole is located on the oil storage cover, and described valve block vertically is arranged at regulates the oilhole port.
Be convenient to assembling, described pump housing front end is connected with a belt pulley housing by a bearing, and be covered on before described in the belt pulley housing front end port, be provided with between port and the spacing convex shoulder and be fixed with described oil storage cover, valve block is attached to the oil storage cover inboard, and valve block withstands in the iron core fixed groove by supporting foot, and the iron core opposite side is near bearing, and described iron core and oil storage cover are located in the belt pulley housing.
As preferably, described bearing and coil are located in the water pump body restraining groove.
Compared with prior art, the invention has the advantages that: adopt the electronic control wheel speed, response is controlled accurately rapidly; Belt drives torsion is big, space province, and layout is convenient; More energy-conservation and environmental protection has reduced water pump and has run up the time, has prolonged the water pump life-span, has reduced noise, has reduced the extra load of motor, has reduced the energy consumption of motor car engine, has played the effect of environmental protection and energy saving.
