简介 Useful model relates down the pump manufacturing, in particular, to the constructions of centrifugal pumps with closed type impeller and magnetic clutch as the drive. The technical result of the declared useful model is the creation of the centrifugal pump with the magnetic clutch, which ensures reduction in the labor expense before the production of magnetic clutch and components of pump, and also increase in its technical and operational characteristics. Technical result is reached before the centrifugal pump with the magnetic clutch, which contains housing (1) with the axial as far as entrance (2) and by radial exhaust (3) by channels, cover (4), placed before the housing (1) axis (5) with the established on it impeller, which consists besides the impeller (6) with the blades (7) and the cover disk (8), in this case working the wheel is connected for the sake of the drive shaft (9) by means of the magnetic clutch, which consists besides the external the leading half-coupling (10), established on the drive shaft (9), and by internal slave half-coupling (11), the established on the nave impeller (6), the half-couplings (10), (11) containing separate heteropolar magnets (12), (13), prepared based on the rare-earth materials with the high [koertsetivnoy] force, with that this additionally containing internal airtight housing (14), that serves after the protective shield between that leading (10) and slave (11) by half-couplings and made from the magnetopermeable material; moreover internal slave half-coupling (11) and impeller (6) impeller they are executed equal diameter, but radial clearance between the magnets (12) external the leading half-coupling (10) and the magnets (13) by internal slave half-coupling (11) comprises not less than 4, 5 mm. before such centrifugal pump with the magnetic clutch preferably : - on external that leading (10) and internal slave (11) half-couplings is established an equal quantity of magnets (12), (13); - magnets (12), (13), established on the half-couplings (10), (11), are executed trapezoidal form; - the arrangement of magnets (12), (13) on the half-couplings (10) and (11) corresponds to relationships , where mi - actual mass of each i-th magnet, φi - position angle of the i-th magnet on the half-coupling, it is n-th the total number of magnets on each half-coupling. 4 p. of formula, 3 illustrations.
