Features
Box structure The structure is reasonable in design, and multiple samples can be tested simultaneously, and related independent operations can be performed without affecting each other. Stable temperature control and high precision. All water contact devices are made of stainless steel (pipes, pipe fittings, heaters, valves, etc.); the bottom of the box is structured, which can carry the weight of the medium and pipe samples in the box; the inside of the box is equipped with sample hanging rods, It is convenient to place the sample.
The temperature control system is controlled by an intelligent interface, and the temperature and control tolerance (upper and lower limits) can be arbitrarily set for PID adjustment. At the same time, it has a recording function that can record the temperature data of the water tank for hundreds of hours, and it can be transmitted to the serial port or USB port.

Description of the characteristics of the pipe hydrostatic test unit
The new features of the latest pressure blasting testing machine have the following characteristics:
① The “precision pressure microcomputer control unit” is placed inside the machine in a multi-channel integrated manner.
②. The communication protocol is more extensive. It can communicate with most display terminals such as computers (PC), programmable controllers (PLC) and touch screens. It can also realize wireless communication under certain conditions (to achieve wireless office), and the communication distance is longer. Far, faster (about 3 times the original).
③, the operation is simpler, only need to set the target pressure value on the PC, and other operations are also more convenient.
④ All the shunts can carry out true linear boost test, the longest time is 59 minutes 59 seconds. As long as the pressure value and time value are set, the pressure can be increased with an approximate linear slope. At the same time, we have carried out a linear pressure increase test on a large diameter pipe with a length of Φ315 and can guarantee the linear increase to about 8MPa within 60S-70S.
⑤ The most important thing is the change of pressure control mode. The pressure compensation valve has been set to full conduction and intermittent conduction (time and frequency can be manually set). The new product uses fuzzy control (fuzzy PID) theory, also called self-tuning theory, to control boost and pressure compensation. The on time and frequency of the valve will be compared with the set value according to the pressure change caused by the last action. With automatic adjustment, both the time and frequency of each action are automatically generated after the comparison operation. It can be said that no matter what the situation, the linear and stable boost can be achieved without overshooting.
⑥The contents of the 12 dialog boxes in the basic test information can be freely set by the user according to different situations and reflected in the test report to form a custom test report.
“Precision pressure control unit” (true branch control-prevent a system from controlling multiple channels and affect all channels when the system fails-some existing products use a system to control multiple channels) industrial panel computer control, you can Control the pressure, accuracy, time and other parameters of each branch; real-time display of pressure, time, status (eight) and storage of each parameter data. (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)
Imported solenoid valve, due to the adoption of the internationally synchronized advanced pressure control method, the two solenoid valves can be operated separately according to the procedures and test conditions to achieve a wide range of applications (Ø20–Ø630PE tube) and high pressure control accuracy (better than ±1%, the highest) Up to ±0.001MPa) requirements.
A set of pressure station for imported water, which has better performance than domestic water pressure test pumps and gas-driven water pumps equipped with some products (gas-driven water), longer life, low noise and no air pump (source).
There is one high-precision sensor for each channel, ensuring a resolution of 0.001 MPa and the highest pressure control accuracy to the set value of ± 0.001 MPa.

Feature of product
A. It is controlled by an industrial tablet computer, integrated printing equipment below, convenient and efficient operation, water and electricity separation design is safe and reliable, and highly integrated modular design makes the volume smaller, easy to place and maintain and manage.
B. From the main system pressure to the pressure of each branch, and then to the different output ports of each branch, three independent control loops are formed, which are isolated from each other and used separately.
C. Each branch is equipped with a “precision pressure microcomputer control unit” designed based on the concept of an industrial computer, which can not only operate for a long time without failure, but also prevent other circuits from being unusable due to a failure of one circuit.
D. The core pressure control element is an imported solenoid valve, which can ensure safe operation for millions of times.
E. 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%.
F. 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.
In addition to the above, it should also explain:
a Reliability, the most in the withstand voltage test

The long-term test is the 8760 test. Except for imports, all of the several domestic testing institutions that have this test item are products of our company.
These equipments have been in operation for 4-5 years, and each test is done for one year, and they are in good condition. Therefore, the reliability of our company’s equipment is very good, and if your equipment wants to carry out this test, it can be guaranteed.
b versatility
Foreign countries generally have strict requirements on test conditions, pressure ranges, products, etc., but not domestically. Many users have a bad test environment, with various materials and various diameters, some require 10MPa and some require 0.05MPa, and they require the equipment to be satisfied, so we have designed the correspondingly.
①. Some users test some products in a large amount for a period of time (the pressure is concentrated in one range), and in another period of time they test a large number of other products (the pressure is concentrated in another range), and sometimes there are more than the range detection of the equipment, so we design The user can change the range by himself.
② When the user changes the range or the user has doubts about the reading or accuracy of the machine, we have designed a self-tuning program in the machine for the user to use.
C. Control method: In the past, the solenoid valve’s energization state was fixed, and the amount of pressure compensation can only be achieved by adjusting the flow rate. Now the logic relationship of the solenoid valve action can be adjusted through different parameter settings to achieve the adjustment of the pressure compensation effect.
