This Emitter and drip irrigation pipe（tape）hydraulic performance testing system( drip irrigation system test machine ) is used for emitter and drip irrigation pipe（tape）hydraulic performance test. The drip irrigation system testing machine includes hydrostatic pressure resistance test in environment temperature, hydrostatic pressure resistance test in high temperature, flow uniformity test, relationship between pressure and flow test, burst test, relationship between pressure loss and flow rate test.
1、The whole equipment basically use stainless steel and other anti rust materials for mechanical structure. It’s has such characteristic, like high corrosion resistance and long service life.
2、Electrical control system is mainly composed in two parts, PLC S7-200 PLC and human-machine interface system (HMI) made of upper computer designed by Wincc6.2 picture configuration software
3、pressure control unit using high precision pressure transmitter and 10 fast PWM pulse width modulation mode with characteristics such as rapid, accurate and stable.
4、Communications using two ways, asynchronous serial communication and synchronization in parallel communication with characteristics such as high speed, reliable, and data throughput.
5、Modular designs by Siemens programmable controller. System function upgrade expansion is very convenient. Truly benefit from one investment.
6、flow measurement unit uses weighing sensor which special in electronic scales and weighing module to ensure reliable performance of electrical, high precision, accurate measuring synchronization, small temperature drift, convenient measurement and calibration.
7、Compression system contains centrifugal pump and frequency conversion controller. With centrifugal pump import from Germany and frequency conversion technique, the system is stable and reliable performance. Flow test water after two-stage filter to ensure clean.
8、constant temperature water supply system contains temperature control system、heating system、cooling system、automatic filling water constant temperature water tank and circulating water system.
9、High temperature test tank contains constant temperature box body, temperature control system, water cycle system, water separator, etc.
