Product Description

Product Description

Synchronous enhancement products stand out in many fields with their superior performance. The synchronous lifting jack in the system is the key component, its internal structure is optimized, the sealing performance is good, and it can stably lift heavy objects under the action of high pressure hydraulic oil. The hydraulic pump station uses a combination of energy-saving motors and efficient oil pumps to provide sufficient power while...
- Hydraulic pump station:
- As a power source for the entire system, providing high pressure hydraulic oil for the jack. It usually includes motor, oil pump, fuel tank, filter and other components. The motor drives the oil pump to operate, and the hydraulic oil in the tank is extracted and pressurized before being transported out.
- The output oil pressure and flow can be adjusted according to the actual engineering needs, and some advanced hydraulic pump stations also have the automatic adjustment function of pressure and flow to adapt to the complex and varied lifting conditions.
- Control system:
- This is the "brain" of the synchronous enhancement product. Data is collected through sensors installed at each lifting point, such as jack travel, speed, load pressure and other information.
- The collected data can be analyzed and processed in real time, and once the difference between different lifting points is found, the automatic command is issued to precisely adjust the hydraulic oil flow and pressure of each jack, thus ensuring that each lifting point moves in sync with the set requirements strictly. The system can also set a variety of lifting modes and parameters, which is convenient for users to flexibly configure according to the specific project.
- Sensor:
- Is a key detection element to achieve synchronous lifting. For example, the displacement sensor can accurately measure the stroke change of the jack, and the pressure sensor can monitor the pressure situation in the hydraulic system in real time.
- The accuracy of the sensor directly affects the accuracy of synchronous enhancement, usually high-precision and high-reliability sensors are used, which can work stably in harsh engineering environments to ensure timely and accurate data feedback.

Working Principle

Synchronous lifting jacks mainly work according to the hydraulic principle and achieve synchronous lifting effect. The hydraulic cylinder has a piston, when the hydraulic pump starts, the hydraulic oil is transported to the hydraulic cylinder with a certain pressure, the piston moves to the other chamber under the hydraulic oil pressure, so that the top rod connected with it rises, thus lifting heavy objects. In terms of synchronous lifting, with advanced sensing and control technology. Sensors installed throughout the jack constantly detect its operating status, including but not limited to the stroke of the jack rod, the speed of movement, and the pressure of the hydraulic system. Once the control system receives the state difference information between different jacks from the sensor, it quickly calculates and corrects the deviation by adjusting the flow and pressure of the hydraulic oil. In this way, each jack can carry out lifting operations in the same rhythm, ensuring the overall stability and flatness when lifting large objects or structures, and meeting the strict requirements of many engineering construction for high precision and synchronization.

 

Installation Instructions

(1) The structure of the new support should meet the design requirements and relevant industry regulations.
(2) The overall replacement of the support construction scheme should be calculated to determine the batch of replacement of the support, the displacement of the top and falling beams and the process.
(3) The temporary support of the lifting beam body should meet the requirements of strength, stiffness and stability.
(4) The lifting and falling of the beam should be carried out according to the design requirements.
(5) When the support is replaced, the deviation of the support should be checked according to the ambient temperature, and the construction should be selected under favorable temperature conditions.
(6) Measure the height difference between the original support and the new support, and adjust the construction to ensure that the beam body and bridge floor elevation meet the reinforcement design requirements. Richard
