One "precision pressure microcomputer control unit" for each channel (true branch control-to prevent a system from controlling multiple channels and affecting all channels when the system has problems-some existing products use one system to control multiple channels) Microcomputer control, you can set and control the pressure, accuracy, time and other parameters of the road independently when the upper system computer is not turned on; the pressure, time, status (eight) are displayed in real time and the data of each parameter is stored. (To prevent data loss when the system computer is offline, it can store up to 8760 hours of pressure data-when some products are offline, no data is equal to this period of time. The test is useless); at the same time, it can distinguish boost, pressure compensation, pressure relief, and overpressure. , Running, ending, leaking, and bursting eight kinds of test states; automatic identification of "effective test time" (the time when the pressure is within the set pressure control tolerance zone), "invalid time", "remaining time" and other time parameters. At the same time, the relationship between "set time" and "effective time" is automatically adjusted so that the test will only stop automatically when the "effective time" reaches the "set time" (to prevent "failure time" and "invalid time" during nights, holidays, etc. When the system stops when the time is not up) B. The control piezoelectric valve imported from the Netherlands, two per circuit. Due to the adoption of advanced pressure control methods synchronized with Denmark, the two electric valves can be operated separately according to the procedures and test conditions to achieve a wide range of applications (Ø20—Ø800PE tube) and high pressure control accuracy (better than ±1% up to ±0.01MPa) ) Requirements.

Distributed control: that is, the "precision pressure microcomputer control unit" on the host and the host computer can be controlled and run independently, and can be online and shut down at any time. 2. From the main system pressure to the pressure of each branch, and then to the different output ports of each branch, an independent control loop is formed, which is isolated from each other and used separately. 3. Each branch is equipped with a "precision pressure microcomputer control unit" designed based on the concept of industrial computer, which can not only operate for a long time without failure, but also prevent other channels from being unavailable due to a failure of one channel (some products on the market use a set of control systems to control each Branch). 4. The core pressure control element is a solenoid valve imported from Germany, which can ensure safe operation for millions of times. 5. There are multiple solenoid valves in each circuit, which are controlled by software programs according to the actual pressure setting to ensure that the pressure is overshoot and the pressure is maintained at a value higher than ±1%. 6. Each branch can also be set with 1-3 output ports, and these three output ports can also be isolated from each other (but can be pressure-compensated), used alone and timed, but each output port can only use one pressure at the same time. 7. The system is designed for rust prevention, and the pressure output tube ensures that it will not be aged for a long time at 95°C. ⑤ Main Technical Parameters A. Pressure range 0-10MPa (maximum pressure 16MPa) B. The resolution is 0.001 MPa at 0-10 MPa, and the resolution is 0.01 MPa at 10 MPa or more C. The precision of pressure control is better than ±1% (pressure control tolerance zone is adjustable-up to ±0.0001 MPa) D. Each control parameter (pressure, time, precision) can be input or adjusted through the upper computer (precision pressure micro-control unit) or the lower computer (computer). E. The upper and lower computers can display the time (up to 9999 hours 59 minutes 59 seconds) pressure (three digits after the decimal point) and eight test states (boost, pressure compensation, pressure relief, operation, end, leakage, Burst) At the same time, there will be an audible and visual alarm when there are four states of overpressure, over, leak, and burst. F. Due to the distributed control mode of dual computer control, the lower computer can be disconnected or turned off for a long time without affecting the system work, and it can ensure that the test data is not lost (maximum 8760 hours) G.
