Description

Suction diffuser for easy screen withdrawal and insertion }

The present invention relates to a suction diffuser, and more particularly, by making it easy to take out and insert a screen disposed inside a body, so as to increase work efficiency such as screen cleaning and replacement, and to be applied to pumps of various specifications It relates to a suction diffuser that can be easily pulled out and inserted into a screen that can increase its utilization by making it possible.

A 'suction diffuser' as disclosed in Korean Utility Model Publication No. 2000-0011464 and the like is applied to a circulation piping system for cooling water, cold water, and heating water.

The suction diffuser is installed on the pump inlet side of the circulation piping system. It lowers the flow rate of the fluid by changing the flow direction, etc. to protect the impeller of the pump from vibration or cavitation caused by vortex, Prevents damage to the pump due to inflow of foreign substances through the included foreign material filter.

On the other hand, when foreign substances accumulate in the suction diffuser, the cylindrical screen is clogged and the efficiency of the pump is reduced, and in particular, as the suction pressure is lowered, a cavity shape is induced, which can lead to damage to the pump.

In order to solve this problem, the inside of the body and the screen are cleaned by removing the cover from the body of the suction diffuser and periodically disassembling the screen inserted and installed inside the body.

However, in the conventional suction diffuser, since the cover is only coupled to the body by fastening a plurality of bolts, and the cover and the body are interconnected, it is necessary to lift and support the cover during the screen extraction and insertion process, which inevitably takes considerable manpower and time. There was a problem in that the efficiency of the cleaning and replacement operation was lowered.

In addition, in the conventional suction diffuser, the diameter of the outlet is manufactured in any one dimension corresponding to the inlet of the pump. If the diameter of the inlet of the pump is changed due to replacement of the pump, the previous application of the suction diffuser cannot be made, so its utility is reduced. There was a problem.

For the above reasons, in the relevant field, by making it easy to take out and insert the screen disposed inside the body, it is possible to increase work efficiency such as screen cleaning and replacement, as well as to increase its utility by being applicable to pumps of various specifications. Although attempts are being made to develop a suction diffuser that allows it, satisfactory results have not been obtained so far.
