Abstract
The invention relates to circulating testing equipment which comprises a liquid storage tank, a pump, a liquid inlet pipe, a liquid outlet pipe, a backflow pipe, a liquid outlet joint and a backflow joint. The liquid storage tank is communicated with the liquid inlet end of the pump through the liquid inlet pipe. The liquid outlet end of the pump is communicated with the liquid outlet joint through the liquid outlet pipe. The backflow joint is communicated with the liquid storage tank through the backflow pipe. The liquid outlet joint is used for connecting a component so that the liquid outlet pipe is communicated with one end of a channel. The backflow joint is used for connecting with the component so that the backflow pipe is communicated with the other end of the channel. The liquid for testing enters the pump from the liquid storage tank through the liquid inlet pipe. After the liquid is pressurized by the pump, the pressurized liquid enters the channel of the tested component through the liquid outlet pipe and the liquid outlet joint. The liquid is circulated in the channel and flows back into the liquid storage tank through the backflow joint and the backflow pipe, thereby realizing liquid circulation. The circulating testing equipment is independent circulating system. The liquid can be circulated and recycled and is not limited by a place water source. Furthermore the circulating testing equipment has advantages of saving water resource and reducing cost.
