Technical Field
The utility model relates to the technical field of machinery, specifically a reduce volume loss structure.
Background
The cavity of the impeller rear cover plate of the water pump structure in the existing market is large in space, as shown in fig. 1, when the water pump operates, part of liquid is separated and does not enter a pump body flow channel, so that part of energy loss is caused, and the efficiency of the water pump is influenced. Accordingly, those skilled in the art have provided a structure for reducing volume loss to solve the problems set forth in the background art described above.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a reduce volume loss structure to solve the problem that proposes among the above-mentioned background art.
In order to achieve the above object, the utility model provides a following technical scheme:
the utility model provides a reduce volume loss structure, includes the pump body and grease chamber lid, pump body top fixedly connected with the grease chamber lid, wear to be equipped with the power shaft in the middle part of the grease chamber lid, the grease chamber lid below lie in the power shaft periphery is provided with the sealed cassette of rotation, the inside sealed rand that is provided with of sealed cassette of rotation, the power shaft is located a pump body tip is provided with the impeller.
As a further aspect of the present invention: the impeller with the power shaft passes through the key-type connection, the pump body with the oil chamber lid passes through the screw connection, can pass through the power shaft drives the impeller rotates, ensures this pump steady operation.
As a further aspect of the present invention: the oil chamber cover with the rotary seal cassette integrated into one piece, sealed rand card is pressed inside the rotary seal cassette, through with the rotary seal cassette with the sealed rand sets up in the top of oil chamber cover changes original structure, can be great reduce the oil chamber cover with distance L between the impeller makes more liquid that takes off the stream get into pump body runner, reduces the charge pump volume loss, promotes charge pump efficiency.
As a further aspect of the present invention: the power shaft and the oil chamber cover are in rotary sealing connection through the rotary sealing clamping seat and the sealing clamping ring, and the sealing clamping ring provides sealing protection for the rotation of the power shaft.
Compared with the prior art, the beneficial effects of the utility model are that:
the utility model discloses a will the rotary seal cassette with sealed cassette sets up in the top of oil chamber cap changes original structure, reduction that can be great the oil chamber cap with distance L between the impeller makes more liquid entering pump body runners that take off a class, reduces charge pump volume loss, promotes charge pump efficiency.

Fig. 1 is a connecting structure diagram of a pump body, an oil chamber cover and an impeller in the prior art;
fig. 2 is a structural diagram of the present invention.
In the figure: 1. an oil chamber cover; 2. an impeller; 3. a pump body; 4. rotating the sealing clamping seat; 5. a sealing collar.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Please refer to fig. 1-2, in an embodiment of the present invention, a structure for reducing volume loss includes a pump body 3 and an oil chamber cover 1, the oil chamber cover 1 is fixedly connected above the pump body 3, a power shaft is inserted into the middle of the oil chamber cover 1, a rotary sealing clamping seat 4 is arranged at the periphery of the power shaft below the oil chamber cover 1, a sealing clamping ring 5 is arranged inside the rotary sealing clamping seat 4, and an impeller 2 is arranged at one end of the power shaft positioned on the pump body 3.
In this embodiment, impeller 2 passes through the key-type connection with the power shaft, and pump body 3 passes through bolted connection with oil chamber cover 1, can drive impeller 2 through the power shaft and rotate, ensures this pump steady operation.
In this embodiment, the power shaft is connected with the oil chamber cover 1 in a rotating and sealing manner through the rotating sealing clamping seat 4 and the sealing clamping ring 5, and the sealing clamping ring 5 provides sealing protection for the rotation of the power shaft.
In this embodiment, grease chamber lid 1 and the sealed cassette 4 integrated into one piece of rotation, sealed rand 5 card is pressed inside the sealed cassette 4 of rotation, through setting up the sealed cassette 4 of rotation and sealed rand 5 in the top of grease chamber lid 1, changes original structure, and the distance L between the reduction grease chamber lid 1 that can be great and the impeller 2 makes more liquid that take off the stream get into the 3 runners of the pump body, reduces the loss of charge pump volume, promotes charge pump efficiency.
Test parameter comparison table of pump before and after improvement:
| flow rate | Head | Efficiency of | Maximum power | Maximum flow | Maximum lift | |
| Before improvement | 25 | 13.28 | 24.69 | 3.969 | 45.89 | 19.56 |
| After improvement | 25 | 13.42 | 26.54 | 3.854 | 51.07 | 19.98 |
As can be seen from the table: by changing the volume between the rear cover plate of the impeller 2 and the oil chamber cover 1, the efficiency of the electric pump is improved by about 2 percent, the hydraulic efficiency of the electric pump is improved by 3 percent, the maximum power is reduced by about 100W, and the electric pump is more efficient and energy-saving by changing the structural design.
The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
