Abstract

The invention provides a pump with a mechanical seal, and belongs to the technical field of water pumps. The problems that according to existing pumps, the service life is short, and the dry frictionof mechanical seals is prone to occurring are solved. The pump with the mechanical seal comprises a connecting seat and an oil cylinder cover, wherein the connecting seat is arranged on a rotating shaft of a motor in a sleeving mode and is used for connecting the motor and a pump body, and the oil cylinder cover is arranged between the connecting seat and the pump body and is arranged on the rotating shaft of the motor in a sleeving mode; the mechanical seal arranged on the rotating shaft of the motor in a sleeving mode is arranged between the connecting seat and the oil cylinder cover; an oilstorage chamber is formed between the connecting seat and the oil cylinder cover; a part of the mechanical seal is positioned in the oil storage chamber; the oil storage chamber is internally provided with mechanical oil in contact with the mechanical seal; and an oil injection hole with the inner end communicating with the oil storage chamber is formed in the connecting seat. The pump with the mechanical seal has the advantages that the lubrication and cooling effects on the mechanical seal are good, and the service life is long.

Example Embodiment

[0015] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solutions of the present invention, but the present invention is not limited to these embodiments.
[0016] like figure 1 The shown pump with mechanical seal 5 includes a connecting seat 3 that is sleeved on the motor shaft 1 for connecting the motor and the pump body 2 and is set between the connecting seat 3 and the pump body 2 and is sleeved on the motor shaft 1. There is a mechanical seal 5 sleeved on the motor shaft 1 between the connecting seat 3 and the oil cylinder head 4 . An oil storage chamber 6 is formed between the connection seat 3 and the cylinder head 4 , and the mechanical seal 5 is partially located in the oil storage chamber 6 . The oil storage chamber 6 has mechanical oil 61 in contact with the mechanical seal 5 . There is an oil injection hole 62 whose inner end communicates with the oil storage chamber 6 .
[0017] like figure 1 As shown, the connecting seat 3 has an annular installation groove 1 31 for installing one end of the mechanical seal 5, and the cylinder head 4 has an annular installation groove 2 41 for installing the other end of the mechanical seal 5. The mechanical seal 5 is located in the annular installation groove 1. 31 and the second annular installation groove 41.
[0018] like figure 1 As shown, the edge of the cylinder head 4 has an annular rib 42 that protrudes axially inward and an annular connecting portion 43 that protrudes radially outward. The annular rib 42 extends into the connecting seat 3, and the connecting portion 43 is screwed Fixed on the connecting seat 3. like figure 1 As shown, a sealing ring 7 is provided between the connecting seat 3 and the cylinder head 4 , and the sealing ring 7 is located between the connecting portion 43 and the annular rib 42 .
[0019] like figure 1 As shown, an oil level line 8 is provided in the oil storage chamber 6 , and the oil filling hole 62 is located above the oil level line 8 .
[0020] The specific embodiments described herein are merely illustrative of the spirit of the invention. Those skilled in the art to which the present invention pertains can make various modifications or additions to the described specific embodiments or substitute in similar manners, but will not deviate from the spirit of the present invention or go beyond the definitions of the appended claims range.
