Detailed Description
The technical solutions of the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model, and it is apparent that the described embodiments are only some embodiments of the present utility model, but not all embodiments, and all other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the scope of protection of the present utility model.
Embodiments of the utility model:
As shown in fig. 1-2, in the embodiment, a first flushing water inlet pipe 1 is provided, the first flushing water inlet pipe 1 is connected with a first flushing branch pipe 2 and a second flushing branch pipe 3 respectively, a first control valve 21, a first Y-shaped hand brush filter 22 and a second control valve 23 are sequentially installed on the first flushing branch pipe 2, a first drain pipe 24 is provided between the first control valve 21 and the first Y-shaped hand brush filter 22, the first drain pipe 24 is connected with the first flushing branch pipe 2, and a third control valve 241 is installed on the first drain pipe 24.
A fourth control valve 31, a second Y-shaped hand brush filter 32 and a fifth control valve 33 are sequentially installed on the second flushing branch pipe 3, a second drain pipe 34 is arranged between the fourth control valve 31 and the second Y-shaped hand brush filter 32, the second drain pipe 34 is connected with the second flushing branch pipe 3, and a sixth control valve 341 is installed on the second drain pipe 34.
The outlet ends of the first flushing branch pipe 2 and the second flushing branch pipe 3 are respectively connected with a second flushing water inlet pipe 4, a mass flowmeter 41 is arranged on the second flushing water inlet pipe 4, the second flushing water inlet pipe 4 is connected with a flushing water outlet pipe after being mechanically sealed, the flushing water outlet pipe is communicated with a pump cavity to realize closed-loop flow of flushing water, and the first sewage drain pipe 24 and the second sewage drain pipe 34 are respectively connected with a sewage drain main pipe 5.
A cooling tower 6 is mounted on the first flushing water inlet pipe 1, and a cooling medium channel 7 is provided in the cooling tower 6, the cooling medium channel 7 being arranged counter-currently to the first flushing water inlet pipe 1, in this embodiment the cooling medium being dry air.
The principle of the utility model is as follows:
When the filter is used, on one hand, the filtering of the mechanical seal flushing water can be realized, so that the mechanical seal damage caused by impurities is avoided, and on the other hand, the back flushing of the filter can be avoided, the manual disassembly and the cleaning are avoided, and the use is more convenient.
When the machine seal flushing water is filtered, the first flushing branch pipe 2 and the second flushing branch pipe 3 are one main and one auxiliary in the process, only one working branch pipe is simultaneously operated, when the machine seal flushing water is backwashed, one working branch pipe is closed, and the other standby branch pipe starts to work, so that the machine seal is ensured to continuously feed water.
Taking the first flushing branch pipe 2 as an example, the second flushing branch pipe 3 is used for standby, flushing water (flushing water is generally process water and is collected at the water outlet end of a water pump) enters the first flushing branch pipe 2 from the first flushing water inlet pipe 1, clean flushing water is obtained after the first Y-shaped hand brush type filter 22 filters the first flushing branch pipe 2, the clean flushing water enters a sealing cavity of a pump body through the second flushing water inlet pipe 4 to cool a mechanical seal, and then is discharged from a water outlet of the sealing cavity and flows into the pump cavity to realize closed loop flow of the flushing water, and in the process, a cooling tower 6 (the cooling tower 6 is conventional and is not repeated) is often arranged on the first flushing water inlet pipe 1 to ensure the flushing cooling effect, and the flushing water is subjected to heat exchange cooling through the cooling water, so that the flushing effect of mechanical seal is ensured.
When the indication of the mass flowmeter 41 is obviously reduced and can not meet the requirement of flushing the pump body in a mechanical seal mode, the first Y-shaped hand-operated brush filter 22 in the first flushing branch pipe 2 is required to be backwashed, at the moment, the fourth control valve 31 and the fifth control valve 33 on the second flushing branch pipe 3 are required to be opened, then the first control valve 21 on the first flushing branch pipe 2 is closed, the second control valve 23 is kept in an open state, the third control valve 241 is opened, flushing water in the first flushing water inlet pipe 1 is partially sealed and cooled through the second flushing branch pipe 3, the other part of the flushing water is required to be backwashed for the first Y-shaped hand-operated brush filter 22, the filter screen in the first Y-shaped hand-operated brush filter 22 can be cleaned by shaking the brush in the process, the cleaned sewage is emptied through the first sewage draining pipe 24, after the cleaning, the second control valve 23 and the third control valve 241 are closed, and the operation is repeated until the indication of the mass flowmeter 41 is reduced again and can not meet the requirement of flushing.
It is noted that the utility model adopts the heating hot water to exchange heat and cool and then to flush the machine pump, and the reason that the cooling water is not adopted to flush directly in the process is that the external water supply is easy to freeze in cold winter, and the stable supply of the cooling water can not be well ensured, so the stable supply of flushing water can be ensured by adopting the heating hot water to exchange heat, and the stable use of the machine seal is ensured.
