Hydraulic wrench is the best tool for driving force instead of physical strength to loosen or tighte
source:Industry News release time:2021-09-28 Article author:Rosit Popular:Air band saw
In practical applications, the installation size of hydraulic wrenches and bolts (composition: head and screw) is large, and it is troublesome to use ordinary wrenches to disassemble, but hydraulic wrenches can solve these problems (Emerson), the advantages of small hydraulic wrenches and torque ( Explanation: It can overwhelm the opponent’s advantageous situation), perfect a flexible and practical alternative (substituting one substance for another (mostly the strong replaces the position of the weak)) lever-type hydraulic wrench wrench, although the traditional volume (volume) is small, But the structure is very simple, as long as the material (Material) is good, the probability (Emerson) is very low (Emerson), but after investigation, more than 50% of all hydraulic wrench accidents are caused by the quality of the bolt itself ( Emerson). The hydraulic wrench transmits power to the working head through the high-pressure oil pipe and the hydraulic pump, which drives the working head to tighten or loosen the nut. The hydraulic pump can be driven by electricity or compressed air. The working head of the hydraulic wrench is mainly composed of three parts, the frame (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 from the center of the oil cylinder to the center of the transmission component is the hydraulic wrench amplification arm. The oil cylinder output multiplied by the arm is the theoretical output torque of the hydraulic wrench. The actual output torque is smaller than the theoretical output torque. There is a traditional wrench. Because it is too large, it is often difficult to tighten the bolts when meeting the standard requirements, but the hydraulic wrench can easily reach the specified (guī dìng) torque. At present, there are two popular (Prevalent) hydraulic wrenches on the market (shì chǎng), namely hydraulic wrenches and hollow hydraulic wrenches. In short, hydraulic wrenches have the characteristics of large power (referring to how much work an object does in a unit time), small size, dexterity (Dexterity), high efficiency (referring to high efficiency), time-saving, labor-saving, strong materials, convenient transportation, etc. . The bad part is more expensive than ordinary wrenches.
