Plastic pipe ultra-high pressure testing machine

XGY-10B-3Plastic pipe ultra-high pressure testing machine

1Overview of Plastic Pipe Ultra High Pressure Testing Machine Products：

Our company is one of the earliest companies in China to produce pipe inspection equipment. At that time, the representative technology was pressure divider technology. Our company used instruments and computers to control, multi valve control, and multi-functional control. Some are still specific now, as the country was one of the earliest to master the technology of pressure control (with different pressures). The upper and lower computer (dual computer) control method was adopted earlier in the country. The same pressure control method as Denmark was adopted earlier nationwide. Large caliber (Ø)630）Pipe fixtures are usedAType fixture.

The product has the characteristics of beautiful appearance, simple structure, high precision, good stability, and easy operation. It is a testing instrument used by various quality inspection departments of research institutes and pipe manufacturers.

3、 Performance Introduction:

1）Each circuit is controlled by a "microcomputer control unit" (true branch control prevents system problems from affecting all circuits when one system controls multiple channels). Some products use one system to control multiple channels. The microcomputer control can independently set and control parameters such as pressure, accuracy, and time of the circuit without turning on the upper system computer; Real time display of pressure, time, and status (eight) and storage of various parameter data. (To prevent data loss when the system computer is offline, pressure data is currently unavailable for some products during this period of time, which is equivalent to testing for nothing); Simultaneously distinguish eight test states: boost, supplement, release, overpressure, operation, end, leakage, and burst; Automatically distinguish time parameters such as "effective test time" (the time when the pressure is within the set pressure control tolerance zone), "invalid time", and "remaining time". Simultaneously adjust the relationship between the "set time" and "effective time" automatically, so that the test will only stop automatically when the "effective time" reaches the "set time" (to prevent the system from shutting down when the time is not up due to "fault time" or "invalid time" during periods such as holidays)

2）Two solenoid valves per circuit. Due to the use of synchronized pressing methods with Germany and Denmark, a piezoelectric valve can change its operating frequency and time according to the program and test conditions, allowing forPEThe rapid and accurate compression of large-diameter specimens can be achieved. Enable the device to achieve a wide range of applicability (Ø)20F630PEHigh pressure control accuracy (better than ±)1%Up to ±0.001Mpa）The requirements.

3）One set of imported water pressure station, which has a larger flow rate, better performance, longer lifespan, lower noise, and does not require an air pump (source) compared to domestic water pressure test pumps and some manufacturers' gas driven water pumps (which require gas driven water).

4）Each high-precision sensor from the Ministry of Space ensures high resolution0.001MpaAnd the high pressing accuracy reaches the set value of ±0.001Mpa.

5）Each pipeline also has several one-way valves and flow regulating valves,It can facilitate the testing of pipe diameters of different sizes and keep the pressure constant in a short period of time.

6）Multi line digital display, multi-channel storage communication, and a wider range of communication protocols, manifested in the ability to communicate with most display terminals such as computers (PCs), programmable logic controllers (PLCs), touch screens, etc

7）A set of branded computers,

4、 Features and composition of this machine:

1Characteristics

1）Continuous barrier free operation ensures the integrity of the experiment;

2）The branches are independent of each other, making it easy to operate and maintain;

3）Equipped with a separate pressurized water tank, the filtered purified water is pressurized into the pipe sample through the main booster pump, ensuring the water quality in the pipeline and improving the service life of pipeline components such as solenoid valves, needle valves, globe valves, and check valves;

4）Using independently developed pulse duty cycle compensation technology, the boost and compensation stages are combined into one, reducing the number of branches and devices and thus reducing the probability of device damage;

5）. The plunger pump made in Taiwan, China, China, has low noise, fast pressure make-up and short working time, which indirectly improves the service life of the plunger pump;

6）Equipped on the basis of instrument controlPCThe machine (i.e. computer) is connected to the instrument through a serial port.

aCan draw pressure time curves,

bReal time query of pressure control values at any time,

c, can print and output reports,

dCan replace manual duty and automatically record pressure values when unattended (such as at night);

e、The computer can stop working at any time while the instrument continues to work.

2Composition description of the equipment:

This testing machine consists of five parts: pressure control system, pressure source, constant temperature medium box, fixture, and computer.

1）The pressure control system in the control cabinet consists of two parts: the pressurization pipeline and the electrical control. The pressurized pipeline consists of components such as an accumulator, solenoid valve, one-way valve, filter, manual needle valve, regulating valve, and connecting pipeline. The electrical control part consists of digital pressure gauges, temperature control instruments, pressure sensors, solenoid valves, relays, overheat protectors, 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, a condenser, and a temperature control system. The box body consists of a stainless steel inner liner, a spray coated outer shell (or stainless steel), an insulation layer, a sample bracket, and a box cover.

4）The fixture isAThe design of the test fixture is more convenient and easy to disassemble and assemble; The wedge-shaped threaded clamping device provides greater clamping force. This series of fixtures has the characteristics of reasonable structure, fast clamping speed, reliable sealing, and easy disassembly.

5）The computer is equipped with a branded machine, which is connected to the control cabinet through a serial port. Brand machines are covered by nationwide warranty and can be maintained at various branches.
