Device for testing water distribution and interaction effect of cooling tower spray devices under different water heads

The invention discloses a device for testing the water distribution and interaction effect of cooling tower spray devices under different water heads. Water is conveyed to a water tank from a water reservoir through a water pump; overflow plates with different heights are arranged in the water tank; water overflowing openings located between the overflow plates and the tank body of the water tank as well as between the overflow plates are formed at the bottom surface of the water tank; the water level of the water tank can be maintained at different heights through changing the open and closed states of the water overflowing openings at different positions, so that tests on the water distribution uniformity of the spray devices under different water heads can be realized; the water can be sprayed through a feed water main, water distribution pipes and the spray devices; the flow rate of the water in the feed water main is acquired through an electromagnetic flowmeter; the pressure of the water in the water distribution pipes is acquired through pressure sensors; flow rate data and pressure data are transmitted to a data acquisition system; and the water can be monitored through a water collecting funnel and a measuring cylinder on a lifting platform, are data are recorded. With the device of the invention adopted, the sprayed water distribution of each spray device in four radial directions of a water spraying region and at different heights under different water heads can be obtained with the influences of surrounding adjacent spray devices considered.
