Description
Technical Field
The utility model relates to a traditional chinese medicine pharmaceutical equipment technical field specifically is a novel waterproof hammer behind pump device.
Background
In the traditional Chinese medicine extraction and concentration industry, the phenomenon of water hammer can occur when materials are conveyed by a traditional power source. The cause of the pressure wave and the factors affecting its magnitude are the sudden change in water velocity, i.e. the root cause of the water hammer. As long as the flow rate of the water changes, the system pressure will necessarily change. It is the blocking action of the check valve that causes the typical "pump-off water hammer" to occur, and the closing of the check valve causes a significant change in the velocity of the water flow, thus creating a dangerous pressure surge. Although the elimination of water hammer by slow closure or two-stage closure, etc. has been recognized for a long time, especially in domestic practice, its applicability is worthwhile to discuss.
