The technical parameters of XGB-10 series pipe hydrostatic testing machine meet the requirements of GB/T6111, GB/T15560 standards, and are suitable for hydrostatic and pipe blasting tests on plastic pipes for various fluid transportation. The product has the characteristics of beautiful appearance, simple structure, high precision, good stability, and convenient operation. It is a necessary testing instrument for quality testing departments of various research institutes and pipe manufacturers.

1. Features: XGB-10 series pipe hydrostatic testing machine This machine has two forms:

1), continuous and barrier-free work can ensure the integrity of the test;

2) The branches are independent of each other, which is convenient for operation and maintenance;

3). Separately equipped with a pressurized water tank, use pure water to add pressure to the pipe sample through the main pressurizing pump to ensure the water quality in the pipeline and improve the pipeline parts (such as solenoid valve, needle valve, stop valve, The service life of one-way valve);

4) Using the self-developed, unique, pulse duty cycle compensation technology, the boost link and the compensation link are combined into one, reducing a branch and device, and reducing the probability of device damage;

5) The use of a plunger pump made in Taiwan has low noise, fast pressure compensation and short working time, which indirectly increases the service life of the plunger pump;

6) On the basis of the instrument control, it is equipped with a PC (ie a calculator), and the serial port is connected to the instrument.

a. The pressure time curve can be drawn,

b. It can query the control pressure value at any time in real time,

c. Reports can be printed out,

d. It can replace manual duty, and automatically record the pressure value when unattended (such as at night);

e. The calculator can stop working at any time, and the meter still continues to work.

F. The latest version of the 2011 hydrostatic software is included when the PC is selected.

2. Description of equipment composition:

XGB-10 series pipe hydrostatic testing machine consists of five parts: pressure control system, pressure source, constant temperature medium tank, fixture and calculator.

1) The pressure control system is composed of two parts: pressurized pipeline and electrical control in the control cabinet. The pressure pipe is composed of accumulator, solenoid valve, one-way valve, filter, manual needle valve, connecting pipeline and other components. The electrical control part is composed of digital pressure gauge, temperature control instrument, pressure sensor, solenoid valve, relay, overheat protector, various switches, etc.

2) The pressure source is used to provide total pressure to the main pressure system according to the test conditions.

3) The constant temperature medium box is mainly composed of a box body, a circulating pump, a heater and a temperature control system. The box body is composed of a stainless steel inner tank, a plastic-sprayed outer shell (or stainless steel), an insulation layer, a sample holder and a box cover.

4) The clamp is A-type, the unique design of the test clamp is more convenient and free; the wedge-shaped and threaded clamping device make the clamping force greater. This series of clamps have the characteristics of reasonable structure, fast clamping speed, reliable sealing and convenient disassembly.

5) The calculator is equipped with a brand-name computer, which is connected to the control cabinet through a serial port. The brand machine is guaranteed nationwide and can be maintained at all locations.

3. Working principle

The working principle of XGB-10 series pipe hydrostatic testing machine is:

1) Set the control pressure and range of the main pressure instrument so that the pressure source provides a pressure of 2～3MPa higher than the highest pressure of the branch and is stored in the accumulator.

2) Calculate the test pressure according to the ring stress requirements of the sample, and set the control pressure and range of the branch pressure meter accordingly. After operation, the meter control solenoid valve is fully turned on, so that the pressure of the sample rises rapidly. When the set pressure is reached, the pressure compensation phase is entered.

3) During the pressure compensation stage, the solenoid valve is turned on intermittently according to the instrument data to supplement the pressure in the pressure source accumulator into the sample.

4) When the pressure of the pressure source drops to the lower limit of the set pressure, the plunger pump starts and stops when it reaches the upper limit.

5) This machine has the functions of running, stopping, leakage warning, and rupture identification at the same time, so that the operator can leave the experimental site during the test. When the sample leaks or ruptures, it will automatically alarm and automatically close the circuit, and other tests will continue to be carried out normally until the test is completed. It has an excellent price-performance ratio among similar models and is an ideal product to replace imports.

6) The machine has a serial port and can be equipped with a calculator, draws a pressure-time curve, can query the control pressure value in real time, can print out reports, can replace manual duties, and can continue to work when the calculator stops working. But the computer does not directly control the solenoid valve, it must be controlled by the instrument, and the instrument cannot stop working during the test. During the test, the computer can be turned off at any time to do other business operations, and the host can work normally. When the host computer is connected with the calculator, the host computer will automatically transmit the data to the calculator machine without any influence on the test.

7) The heating in the main tank of the water tank can ensure the life of the heating tube, and the extracorporeal circulation makes the water temperature in the water tank even. The constant temperature medium water tank has two specifications: single heating type and cooling and heating type.
