System can cool down mechanical seal, while effectively prevent the granule foreign deposited on dynamic and static ring sealing face, to effectively protect
Dynamic and static ring sealing face is protected, improves sealing effect, and then ensure the operation of the normal table of the pump housing, after the completion of flushing terminates, due to
There are gaps for the junction of mechanical seal chamber and pump chamber and shaft, therefore industry water can be by the gap via mechanical seal chamber to pump
Chamber is discharged, to complete to rinse finally as pump chamber works via the water outlet of pump chamber.
And when needing for the industry water in the second branch pipe 4 to be discharged out of rinse-system, i.e., unlatching the 5th control valve 21 from
And realize that industry water is flowed out from leakage hole 20, to guarantee the cleaning in flushing pipe 1；
Then when blocking occurs for the filter 9 on the first branch pipe 3 or other components are damaged, visor 10 is observed
It is interior to be flowed through without flushing liquor, and the pressure decline of the pressure gauge 11 of 6 upper end of outlet tube, at this time by the third control of the first branch pipe 3
The second control valve 15 on valve 14 processed and the second branch pipe 4 is closed, and is cleaned to realize to the filter 9 on the first branch pipe 3；
And the 4th control valve 19 is opened simultaneously, so that industry water be promoted to enter from inlet tube 2 via the 4th branch pipe 16 and the 5th branch pipe 17
Third branch pipe eventually enters into outlet tube 6, so that it is clear to realize that 1 tunnel of flushing pipe of another way can continue to keep to carry out mechanical seal
It washes, reduces the loss of mechanical seal, whole process can guarantee the normal work of mechanical seal without stopping cleaning system.
The embodiments of the present invention are described in detail above, but content is only the preferable implementation of the utility model
Example, should not be considered as limiting the scope of the present invention.It is all according to equivalent change made by the scope of the utility model with
Improve etc., it shall still fall within the scope of this patent.
