As shown in fig. 4, the waterway system includes: the device comprises a water inlet pipeline, a water supply pipeline, a pressure relief pipeline, a drainage pipeline and a circulating pipeline.
Wherein the water inlet pipeline: tap water is connected to the water inlet 4, water flows into the water source water tank 15 through the water inlet 4 and passes through the water inlet control valve 21, a water tank level gauge 26 is arranged in the water source water tank 15, the liquid level in the water source water tank is controlled through the water tank level gauge 26, and various liquid level values required by experiments can be set on the control panel 6.
The water supply pipeline comprises: the experimental pressure is set on the control panel 6, then the variable frequency water supply pump 16 is started, and water flow reaches the water supply port 2 from the water source tank 15 through the maintenance valve 34, the filter 35, the flowmeter 28, the stop valve 29, the pressure sensor 25 and the manual ball valve 30 in sequence. The variable frequency water supply pump 16 automatically adjusts and corrects the pressure signal fed back by the front-end pressure sensor 25 to enable the front-end water supply pressure to reach a set value. The flow meter 28 in the water supply line provides real-time flow as well as cumulative flow, both of which are displayed on the control panel 6.
Pressure release pipeline: in order to prevent the pressure-holding phenomenon of the variable frequency water supply pump 16 caused by closing the manual ball valve 30 due to the replacement of the sample to be detected in the middle, a pressure relief pipeline is arranged at the outlet position of the variable frequency water supply pump 16, and under the condition that the manual ball valve 30 in the water supply pipeline is closed, water flow can return to the water source water tank 15 through the pressure relief pipeline via the pressure relief valve 36, so that a protection measure is taken for the good operation of the whole pipeline system.

The sewage drawer 13 and the filter drawer 17 below the experiment table 1 are respectively arranged on two drawer moving bases 19 in parallel side by side, the rear ends of the two drawer moving bases 19 are connected with a base moving guide rail mechanism 23, and the front ends are connected with a roller mechanism 18. The drawer moving base 19 can horizontally move left and right along with the roller mechanisms 18 and the base moving guide rail mechanisms 23 at the front and rear ends, so that the left and right moving friction force of the drawer moving base 19 and noise generated in the moving process are reduced. The sewage drawer 13 and the filtering drawer 17 move left and right along with the drawer moving base 19, and can be pulled or directly pulled out along the front and back positions of the equipment when the drawer moving base 19 is aligned with the strip-shaped holes on the working table. The requirement of changing the drawers back and forth in different experiments is met, the operation is simple and convenient, only the sewage drawer 13 and the filtering drawer 17 need to be moved back and forth left and right, the manual work is omitted, the sewage drawer 13 and the filtering drawer 17 are pulled out back and forth to be replaced, and the experiment requirement is met.
