Product features: One-click to complete all automatic tension control operations, password locking and storage and recording of the entire process, and remote real-time monitoring of the entire tension construction process. It is conducive to the perfect control of the quality of the tensioning of the project, and effectively eliminates the hidden danger of engineering accidents caused by the tensioning construction without social responsibility
Product system performance: The system flow is a variable pump, and the variable is a small flow when it is close to the tension control pressure, which effectively ensures the accuracy when the preset tension pressure value is reached. The machine can be adjusted manually and fully automatic. In the fully automatic tensioning mode, one key is used to complete automatic tensioning, automatic shutdown and pressure maintenance, automatic unloading, and automatic return. The stretching length value is fully automatically controlled by the computer, and the stretching length value is automatically calculated to obtain the result. The stretching record parameters can be printed immediately on the spot. The U disk storage record can transmit and store the stretching data in real time through the wireless network, and the touch screen mode is easy to preset. Various parameters of tensioning, the tensioning can be controlled without placing a computer on site, and one oil pump operator can control and monitor four oil pumps working at the same time, and the supervisor and the owner can monitor the whole process through the computer network in the office. Control 1~4 tensioning pump stations and tensioning jacks to carry out tensioning construction at the same time. The design of this system fully considers the harsh working conditions of the construction site. The machine has a certain anti-rain function, and the heat dissipation structure of the machine is designed
It effectively solves the continuous and high-strength construction in the hot summer in the south. Another major design feature of this system takes into account the damage and failure of the ultra-high pressure solenoid valve. The temporary and simple change of the oil circuit can also ensure that the construction site can complete the tensioning according to the automatic tensioning mode. The whole process can ensure non-stop construction after this situation occurs
Detailed product description: The distance between the main pump and the auxiliary pump is not more than 200M, and the auxiliary pump will be displaced,
The pressure signal is transmitted to the main pump. After the main pump processes the signal, it transmits the control signal to the auxiliary pump to control the oil supply, stop, and oil return of the jack. At the same time of tensioning construction, the on-site tensioning parameters of the main pump are wirelessly transmitted to the on-site monitoring computer, and then the on-site monitoring computer uploads the tensioning data to the special query website or self-built website established by our company. Pull date query to download tension parameters. Or directly transmitted to the owner's supervision by the on-site monitoring computer. At the same time, the control module of the main pump can store about 40,000 tensioning parameters to prevent the loss of tensioning parameters due to transmission problems.

2. Product use:
The prestressed tensioning equipment produced by our company has a wide range of uses and is mainly used for various pre-tensioning or post-tensioning methods of cement components such as roads and bridges, tunnels, hydropower dams, water conservancy aqueducts, slope protection anchoring, cable-stayed, buildings, and steel components. prestressed tension.
3. Selection and requirements of intelligent tensioning equipment:
1. The rated tonnage of the tension jack should be 1.5 times the tension force, and should not be less than 1.2 times. It must be calibrated before use, and the calibration coefficient should not be greater than 1.05. The calibration is valid for one month and does not exceed 200 tensioning operations. The stroke of the tensioning jack should meet the requirements of the tensioning process;
2. The pressure gauge should be of anti-vibration type, and the maximum reading should be 1.5 to 2.0 times the corresponding pressure value of the tension force. Jing's degree should not be lower than 1.0. It must be verified by the measurement department before the first use. It must be checked regularly when used. The check is valid for one week. When using level 0.4, the check is valid for one month;
3. The rated pressure of the oil pump should be 1.4 times the corresponding pressure value of the tension force. The capacity of the oil tank should be 1.5 times the total oil delivery capacity of the tension jack;
4. The tension jack, pressure gauge, and oil pump should be calibrated and used together. When an abnormal phenomenon occurs during use, it should be re-calibrated.
Product composition and working principle:
1. The prestressed intelligent tension control system is used for automatic control of bridge prestressed tension. It adopts a touch screen or laptop computer and high-performance logic controller to control 2-cylinder or 4-cylinder synchronous tension through the proportional valve. The system is easy to operate, the whole tensioning process can be completed with one key operation, and the height of the tension can be controlled, which can effectively improve the prestressed construction time, tension, quality, and safety.
2. Components and working principle of intelligent tensioning equipment: The system consists of a computer or industrial computer, PLC, analog conversion module, sensor, power box, oil pump, oil tank, pressure gauge, chassis shell, jack, high-pressure oil pipe, and other parts. The prestress tensioning program control system takes the tension force as the control index and the elongation error as the proofreading index. The system collects data such as the working pressure of each tensioning equipment (jack) and the elongation (including retraction) of each tensioning device through sensor sensing and transmits the data to the system computer in real time for calculation and judgment, and then returns the data to the system. Send it to the PLC to adjust the working parameters of the oil pump motor at any time to control the amount of oil output to obtain the required pressure value, so as to realize the jing que control of high-precision tension force and loading speed.
6. Product system technology and features:
1. One machine control double top
One intelligent tensioning master or slave can control two jacks. When the two-beam four-cylinder tensioning is performed, only two masters and slaves are needed, which reduces costs, is simple to operate, and is easy to use.
2. The high-pressure oil pump controls the tension force through the high-pressure proportional valve, the tension is smooth and stable, the accuracy is correspondingly improved and the error ratio is reduced.
Compared with the models that control the synchronous tensioning by switch mode or large and small flow, the proportional valve is used to control the tensioning, the speed is more uniform, the control is more accurate, and the operation is simpler.
3. It adopts industrial computer dedicated logic programming control, and the core controller adopts the logic controller specially programmed for bridge tensioning, which has fast operation speed, high stability, and convenient maintenance.
4. Using an industrial touch screen or laptop wireless control, the screen display is clear and the operating status of each work is clear at a glance, the operation is stable and reliable, and the failure rate is low.
