Abstract
The utility model relates to an electric pump which comprises a front end closure (1), a back end closure (9), a lower pump casing (2), a static sealing part (3), a dynamic sealing part (4), an impeller (5), and a motor rotating shaft (7), wherein, two ends of the motor rotating shaft (7) are supported on the front end closure (1) and the back end closure (9) through bearings (8), the lower pump casing (2) is arranged on the outer side of the front end closure (1), and the impeller (5) is fixed on the motor rotating shaft (7) through a connecting piece (6), and arranged on the outer side of the lower pump casing (2). Besides, the end part of the lower pump casing (2) is made into a hollow cylindrical casing (21), a flange (11) realizing the positioning with the outer wall of the cylindrical casing (21) at the end part of the lower pump casing (2) is made on the front end closure (1), the dynamic sealing part (4) is sleeved on the motor rotating shaft (7), and the static sealing part (3) is sleeved on the inner wall of the cylindrical casing (21) at the end part of the lower pump casing (2). The utility model ensures the concentricity requirement of the dynamic sealing part and the static sealing part when the electric pump operates, thereby avoiding the scratch and damage formed on the surfaces of the sealing parts and the water leakage of the electric pump and effectively improving the operation reliability of the electric pump.
Description
Technical field
The utility model is a kind of electric pump, and particularly a kind of electric pump that is used for dishwasher belongs to the renovation technique of electric pump.
Background technique
The existing electric pump that is used for dishwasher when mounted, its front cover and following pump case adopt the structure of hook or screw installing and locating more, the quiet concentricity that is installed in the dynamic seal on the motor shaft and is installed in down on the pump case guarantees that ability is relatively poor, the washing electric pump is under the proper functioning operating condition, the situation of swiping mutually in inside and outside edge can appear in static and dynamic sealing spare, cause seal surface cut damage to occur, so that the electric pump situation of leaking occurs.
The model utility content
The purpose of this utility model is to consider the problems referred to above and a kind of electric pump concentricity requirement of dynamic and static Sealing in the running of guaranteeing is provided, and effectively avoids seal surface the cut damage to occur, avoids electric pump the electric pump of the situation of leaking to occur.The utility model is reasonable in design, has effectively improved the electric pump reliability of operation.
The technical solution of the utility model is: include front cover, rear end cover, following pump case, static seal, dynamic seal, impeller, machine shaft, wherein the two ends of machine shaft are bearing on front cover and the rear end cover by bearing respectively, following pump case is installed in the outside of front cover, impeller is fixed on the machine shaft by link, and be positioned at the outside of pump case down, wherein descend the end of pump case to make hollow cylindrical shell, make the flange of realizing the location with the outer wall of the set cylindrical housings in following pump case end on the front cover, dynamic seal is sleeved on the machine shaft, and static seal is sleeved on down on the inwall of the set cylindrical housings in pump case end.
Above-mentioned link is a nut.
The utility model is because employing has been made hollow cylindrical shell in the end of pump case down, make the structure that realizes the flange of location with the outer wall of the set cylindrical housings in following pump case end on the front cover, moving when having solved the electric pump running, the requirement of static seal concentricity, effectively avoided the washing electric pump under the proper functioning operating condition, in the static and dynamic sealing spare, the situation that outward edge is swiped mutually takes place, reduced eccentric swing because of Sealing, the sealing surfaces that causes the particulate contamination lapping-in to advance Sealing causes seal surface the cut damage to occur, and then the ratio that causes the electric pump situation of leaking to occur, improved the electric pump reliability of operation.The utility model is an electric pump a kind of reasonable in design, simple in structure, convenient and practical.

Fig. 3 is the structural representation of front cover in the utility model.
Embodiment
Embodiment:
Structural representation of the present utility model such as Fig. 1, shown in 2, include front cover 1, rear end cover 9, following pump case 2, static seal 3, dynamic seal 4, impeller 5, machine shaft 7, wherein the two ends of machine shaft 7 are bearing on front cover 1 and the rear end cover 9 by bearing 8 respectively, following pump case 2 is installed in the outside of front cover 1, impeller 5 is fixed on the machine shaft 7 by link 6, and be positioned at the outside of pump case 2 down, wherein descend the end of pump case 2 to make hollow cylindrical shell 21, make the flange 11 of realizing the location with the outer wall of the set cylindrical housings 21 in following pump case 2 ends on the front cover 1, dynamic seal 4 is sleeved on the machine shaft 7, and static seal 3 is sleeved on down on the inwall of the set cylindrical housings 21 in pump case 2 ends.In the present embodiment, above-mentioned link 6 is a nut.
The utility model when mounted, the hollow cylindrical shell 21 that the following end of pump case 2 is made is sleeved in the cylindrical shrinkage pool that front cover 1 surrounded by its flange 11, thereby make down the installation requirement that satisfies concentricity between pump case 2 and the front cover 1, in addition, because of dynamic seal 4 is sleeved on the machine shaft 7, static seal 3 is sleeved on down on the inwall of the set cylindrical housings 21 in pump case 2 ends, so also guaranteed to satisfy between dynamic seal 4 and the static seal 3 installation requirement of concentricity, thereby effectively avoided the washing electric pump under the proper functioning operating condition, in the static and dynamic sealing spare, the situation that outward edge is swiped mutually takes place, reduced eccentric swing because of Sealing, the sealing surfaces that causes the particulate contamination lapping-in to advance Sealing causes seal surface the cut damage to occur, and then the ratio that causes the electric pump situation of leaking to occur, improved the electric pump reliability of operation.
Claims (2)
1, a kind of electric pump, include front cover (1), rear end cover (9), following pump case (2), static seal (3), dynamic seal (4), impeller (5), machine shaft (7), wherein the two ends of machine shaft (7) are bearing on front cover (1) and the rear end cover (9) by bearing (8) respectively, following pump case (2) is installed in the outside of front cover (1), impeller (5) is fixed on the machine shaft (7) by link (6), and be positioned at the outside of pump case (2) down, it is characterized in that hollow cylindrical shell (21) has been made in the end of pump case (2) down, make the flange (11) of realizing the location with the outer wall of the set cylindrical housings in following pump case (2) end (21) on the front cover (1), dynamic seal (4) is sleeved on the machine shaft (7), and static seal (3) is sleeved on down on the inwall of the set cylindrical housings in pump case (2) end (21).
