Reliable and stable systems
Description:
- The water tank is arranged with a low level switch and a high level switch, through the automatic replenishment of water to keep the water tank level at a high level, due to the inability to timely replenish the water level to reach the low level will trigger a system alarm
- The water tank replenishment circuit is arranged with a filter to avoid debris from entering the water tank and blocking the nozzle, and the filter needs to be replaced regularly.
- The pump suction port is arranged with a filter to avoid debris entering the pump and causing damage.
- The flow rate is regulated by a proportional three-way valve, and the proportional valve is regulated by the flow rate value collected by the flow sensor to achieve precise and stable control of the flow rate.

Grundfos compact, highly reliable horizontal multistage, end-suction centrifugal pumps with axial suction and radial discharge ports for providing sufficient water flow to the water circuit; the pump body in contact with the liquid is made of stainless steel and the pump is fitted with a 3-phase asynchronous motor with a cooling fan; the pumps are small, quiet and reliable!
Danfoss electric intelligent control valve, used to control the flow of the water circuit to meet the test standard requirements; control valve by the regulating valve and pressure relief control valve, control signal automatic disconnection monitoring, free self-checking and positioning, anti-oscillation, overheating and overload protection and other functions, to ensure the stability and accuracy of control
Vortex flow sensor, used to measure the flow in the water circuit, providing analog signals to the control system for flow control; quick-insertion installation, easy to disassemble and calibrate; contaminants in the fluid have no effect on the measuring element, small pressure loss, with very high accuracy
Measuring range 0~16bar, used to measure the pressure in the water circuit, provide analog signal to the control system for pressure monitoring; 304 stainless steel, better than 0.3% of full scale accuracy, threaded connection, easy to disassemble and calibrate.
Siemens SINAMICS V90 servo system with absolute encoder for pendulum motion and incremental encoder for rotary table rotation; precise position and speed control and easy system wiring.
Siemens SIMATIC S7-1200 controller, integrated PID control function, to ensure the accurate control of water flow, efficient operation ability to ensure that the system can be controlled in real time.
Simple and easy-to-use operation
① The main signals of the equipment and alarm trigger display, such as power supply phase sequence, motor failure, box door signal, etc.
② water tank temperature, pipe pressure, pipe flow and turntable speed curve display
③ Each angle nozzle operation and timing display
④ Test progress display
⑤ Equipment operation information prompts
⑥ Protected run and stop touch keys, each operation needs to be confirmed.
① The spraying time of each nozzle can be set individually, and the nozzle with a spraying time of 0 does not work.
② The interval time between two neighboring nozzles can be set, and an interval time of 0 means continuous spraying.
③ The interval time of each test cycle can be set, and the interval time of 0 means continuous operation.
④ Rotary table speed can be set up to 20r/min.
⑤ The maximum value of water tank temperature setting is 85℃.
⑥ Each parameter modification needs to be saved before taking effect.
