Abstract
The utility model discloses a kind of pump cover bracket assembly of magnetic drive pump, it comprises pump cover, outer ring, inner ring and support end plate, described outer ring and inner ring are between pump cover and support end plate, described outer ring is respectively arranged with steam ingress pipe and steam delivery line near the upper and lower of support end plate, closed toroidal cavity is formed between described outer ring and inner ring, described inner ring is provided with the through hole being convenient to steam turnover pump cover cavity near the side of pump cover, between described pump cover and support end plate, forms cylindrical cavity.The pump cover bracket assembly of a kind of magnetic drive pump of the utility model adopts such structure, is input into steam during use from steam ingress pipe, and steam enters in the toroidal cavity of pump cover bracket assembly, and steam enters pump cover cavity from the through hole of pump cover bracket assembly inner ring simultaneously.The easy crystalline material had in cylindrical cavity is melted by the heat transfer of pump cover bracket assembly inner ring by steam, reduces the resistance of start, extends the working life of bearing, reduce maintenance cost.
Description
Technical field
The utility model relates to pump, particularly relates to a kind of pump cover bracket assembly of magnetic drive pump.
Background technique
Magnetic drive pump comprises housing, impeller, pump cover, pump shaft, interior magnet rotor, support, separation sleeve, outer magnet rotor, motor and is positioned at the liner plate of motor end, outer magnet rotor and motor shaft affixed, interior magnet rotor and pump shaft affixed, separation sleeve connects with pump cover, the outer magnet rotor of driven by motor rotates, in driving, magnet rotor rotates again, and interior magnet rotor is driven member.During shutdown, the not emptying easy crystal medium in housing, pump cover, interior magnet rotor place solidifies and becomes powdery, bulk, and again start, resistance is large, can cause bearing damage, even cannot start, this just need to solidify become powdery, block easy crystal medium melts.Also do not have the pump cover bracket assembly of such magnetic drive pump at present, its use can be melted the easy crystalline material in pump chamber, thus extends the working life of bearing.
Model utility content
Technical problem to be solved in the utility model is: the pump cover bracket assembly providing a kind of magnetic drive pump, and the use of the pump cover bracket assembly of this kind of magnetic drive pump can be melted the easy crystalline material in pump chamber, thus extends the working life of bearing.
Solve this technical problem, the technical solution of the utility model is: a kind of pump cover bracket assembly of magnetic drive pump, it comprises pump cover, outer ring, inner ring and support end plate, described outer ring and inner ring are between pump cover and support end plate, described outer ring is respectively arranged with steam ingress pipe and steam delivery line near the upper and lower of support end plate, closed toroidal cavity is formed between described outer ring and inner ring, described inner ring is provided with the through hole being convenient to steam turnover pump cover cavity near the side of pump cover, cylindrical cavity is formed between described pump cover and support end plate.
Described heat-insulation support and pump cover are shape all-in-one-piece structure.
Described steam ingress pipe and steam delivery line removably connect with the outer ring of heat-insulation support respectively.
The pump cover bracket assembly of a kind of magnetic drive pump of the utility model adopts such structure, is input into steam during use from steam ingress pipe, and steam enters in the toroidal cavity of pump cover bracket assembly, and steam enters pump cover cavity from the through hole of pump cover bracket assembly inner ring simultaneously.Although steam cannot enter cylindrical cavity, by the heat transfer of pump cover bracket assembly inner ring, the easy crystalline material had in cylindrical cavity is melted, reduce the resistance of start, extend the working life of bearing, reduce maintenance cost.
Accompanying drawing explanation
Be described in further detail below in conjunction with the pump cover bracket assembly of accompanying drawing to a kind of magnetic drive pump of the utility model;
Fig. 1 is the structural representation of the pump cover bracket assembly of a kind of magnetic drive pump of the utility model;
The pump cover bracket assembly using state structural representation that Fig. 2 is a kind of magnetic drive pump of the utility model shown in Fig. 1;
In Fig. 1, Fig. 2,1, housing; 2, impeller; 3, pump cover; 4, pump shaft; 6, steam ingress pipe; 7, outer magnet rotor; 8, liner plate; 9, interior magnet rotor; 10, motor shaft; 11, separation sleeve; 12, steam delivery line; 13, base; 14, toroidal cavity; 15, through hole; 17, support end plate; 18, cylindrical cavity; 19, inner ring; 20, outer ring.
Embodiment
As Fig. 1, shown in Fig. 2, magnetic drive pump comprises housing 1, impeller 2, pump shaft 4, pump cover bracket assembly, outer magnet rotor 7, liner plate 8, interior magnet rotor 9, motor shaft 10, separation sleeve 11 and base 13, outer magnet rotor 7 is affixed with pump shaft 4, interior magnet rotor 9 is affixed with motor shaft 10, separation sleeve 11 connects with liner plate 8, pump cover bracket assembly comprises pump cover 3, outer ring 20, inner ring 19 and support end plate 17, outer ring 20 and inner ring 19 are between pump cover 3 and support end plate 17, outer ring 20 has steam ingress pipe 6 and steam delivery line 12 respectively near the upper and lower of support end plate 17, steam ingress pipe 6 and steam delivery line 12 removably connect with outer ring 20 respectively, closed toroidal cavity 14 is formed between outer ring 20 and inner ring 19, inner ring 19 has the through hole 15 being convenient to steam turnover pump cover cavity near the side of pump cover 3, cylindrical cavity 18 is formed between pump cover 3 and support end plate 17.Pump cover, outer ring, inner ring and support end plate are shape all-in-one-piece structure, and outer magnet rotor 7, interior magnet rotor 9 and isolation 11 cover are positioned at this cylindrical cavity 18.
Such structure, is input into steam from steam ingress pipe during use, and steam enters in the toroidal cavity of pump cover bracket assembly, and steam enters pump cover cavity from the through hole of pump cover bracket assembly inner ring simultaneously.Although steam cannot enter cylindrical cavity, by the heat transfer of pump cover bracket assembly inner ring, the easy crystalline material had in cylindrical cavity is melted, reduce the resistance of start, extend the working life of bearing, reduce maintenance cost.
