Abstract
The present invention relates to a kind of transmission device for Miniature water-pumping pump, including transmission shaft, the protective case of one end open is socketed with the outside of the transmission shaft, and transmission shaft is connected with impeller close to the end of protective case openend;An annular magnet ring is equipped with the protective case openend, and annular magnet ring is also arranged with groove on one end end face of impeller.The advantage of the invention is that:The present invention is used for the transmission device of Miniature water-pumping pump, compared with existing transmission device, adds groove on magnet ring, the setting of groove can avoid drawing water pump work when, since heat is excessive, there is dry combustion method phenomenon;Meanwhile 1/3 that the depth of groove is magnet ring depth, depth can be avoided excessive, influence the transmission effect of transmission device.
Description
Technical field
The invention belongs to water suction pump device, more particularly to a kind of transmission device for Miniature water-pumping pump.
Background technology
Suction pump is the effect using atmospheric pressure, and water is promoted to the hydraulic of eminence from lower.It is by water pump, power
Machinery is formed with transmission device.It is widely used in the feedwater of field irrigation, draining and industrial and mining enterprises and cities and towns, draining.
Now widely used suction pump, including pump cover, the pump housing, connecting seat, transition connecting seat, bearing block, bearing, transmission
Axis, transmission device, impeller, water seal, wherein, magnet ring is equipped between transmission shaft and impeller, but dry combustion method easily occurs in existing transmission device
Phenomenon.
Therefore, it is that have very much must to research and develop a kind of transmission device for being used for Miniature water-pumping pump that can avoid the occurrence of dry combustion method phenomenon
Want.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of Miniature water-pumping that is used for that can avoid the occurrence of dry combustion method phenomenon to pump
Transmission device.
In order to solve the above technical problems, the technical scheme is that:A kind of transmission device for Miniature water-pumping pump, its
Innovative point is:Including transmission shaft, the protective case of one end open is socketed with the outside of the transmission shaft, and transmission shaft is close to protection
The end of set openend is connected with impeller;An annular magnet ring is equipped with the protective case openend, and annular magnet ring is close to impeller
One end end face on be also arranged with groove.
Further, the depth of the groove is the 1/3 of magnet ring depth.
The advantage of the invention is that:The present invention is used for the transmission device of Miniature water-pumping pump, compared with existing transmission device,
Add groove on magnet ring, the setting of groove can avoid drawing water pump work when, since heat is excessive, there is dry combustion method phenomenon;It is meanwhile recessed
The depth of groove is the 1/3 of magnet ring depth, and depth can be avoided excessive, influence the transmission effect of transmission device.
Brief description of the drawings
The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
Fig. 1 is the structure diagram for the transmission device that the present invention is used for Miniature water-pumping pump.
Fig. 2 is the structure diagram of Fig. 1 middle magnetic rings.
Embodiment
The following examples can make professional and technical personnel that the present invention be more fully understood, but therefore not send out this
It is bright to be limited among the embodiment described scope.
Embodiment
The present embodiment is used for the transmission device of Miniature water-pumping pump, as shown in Figure 1, including transmission shaft 1, the transmission shaft 1
Outside is socketed with the protective case 2 of one end open, and transmission shaft 1 is connected with impeller 3 close to the end of 2 openend of protective case;It is described
An annular magnet ring 4 is equipped with protective case openend, as shown in Fig. 2, annular magnet ring 4 is also symmetrical on one end end face of impeller 3
Equipped with groove 5, and 1/3 that the depth of groove 5 is 4 depth of magnet ring.
The present embodiment is used for the transmission device of Miniature water-pumping pump, and compared with existing transmission device, groove is added on magnet ring 4
5, the setting of groove 5 can avoid drawing water pump work when, since heat is excessive, there is dry combustion method phenomenon;Meanwhile the depth of groove 5 is
The 1/3 of 4 depth of magnet ring, can avoid depth excessive, influence the transmission effect of transmission device.
The basic principle and main feature and advantages of the present invention of the present invention has been shown and described above.The skill of the industry
Art personnel it should be appreciated that the present invention is not limited to the above embodiments, the above embodiments and description only describe
The principle of the present invention, without departing from the spirit and scope of the present invention, various changes and modifications of the present invention are possible, these
Changes and improvements all fall within the protetion scope of the claimed invention.The claimed scope of the invention by appended claims and
Its equivalent thereof.
