Hydraulic wrench pressure comparison table
source:Industry News release time:2021-04-09 Article author:Rosit Popular:Air band saw
A set of hydraulic wrench is composed of a working head, an electric hydraulic pump, a double high-pressure oil pipe, and a high-strength sleeve. The electric hydraulic pump transmits the power source to the hydraulic wrench through the double high-pressure oil pipe. More specifically, the electric hydraulic pump generates pressure internally through the electric motor after the electric hydraulic pump is started, and transmits the internal hydraulic oil to the hydraulic wrench through the oil pipe medium, and then pushes the hydraulic pressure. The piston rod of the wrench is driven by the piston rod to drive the ratchet wheel at the front of the wrench so that the ratchet wheel can drive the drive shaft to complete the bolt pre-tightening work.
Among them, the supporting products of hydraulic wrenches, electric hydraulic pumps are: solenoid valve drive (electric) or compressed air drive (pneumatic). The working head of the hydraulic wrench is mainly composed of three parts, the body (also called the shell), the oil cylinder and the transmission parts. The output force of the oil cylinder, the piston rod of the oil cylinder and the transmission part form a motion pair. The distance between the center of the oil cylinder and the center of the transmission component is the hydraulic wrench amplified lever arm. The oil cylinder output multiplied by the lever arm is the theoretical output torque of the hydraulic wrench. The actual output torque is caused by the friction resistance. Less than the theoretical output torque.
The importance of hydraulic wrench synchronization system:
The main purpose is to avoid the unilateral compression mode of the flange surface, which will cause the gasket on the flange surface to fail due to excessive extrusion, causing leakage. The synchronization system is to use two or four hydraulic wrenches connected to one pump at the same time. According to the hydraulic principle, multiple hydraulic wrenches work at the same time and output the set torque at the same time to realize the parallel closing of the flange, and the torque accuracy can reach 3%. The synchronization system can lock the bolts at one time, while the single system needs to be loaded multiple times and locked step by step. It can be seen that the efficiency of the synchronization system is far greater than that of the single system. For larger wrenches, it is recommended to use a hydraulic wrench pump control amount synchronization system, or a system where two pumps and two wrenches are locked at the same time.
