Due to its special structure, coupled with greater power and flexibility than humans, the range of use of hydraulic wrenches (fàn wéi) is very extensive, such as ships (paraphrase: general name for ships) (meaning: large sailing ships) , Such as petrochemicals, such as construction, electricity, etc., especially in places with a relatively large workload. Hydraulic wrench is the abbreviation of hydraulic torque wrench. It is a professional bolt tightening tool that is powered by hydraulic pressure and provides high torque output. It is used for bolt installation and disassembly. It is often used to tighten and loosen bolts larger than one inch. The hydraulic wrench is composed of a working head, a hydraulic pump and a high-pressure oil pipe. The larger the specifications, the more troublesome it is to install and remove the screws using ordinary wrenches, but hydraulic wrenches solve this problem (Emerson), with small volume, large strength, dexterity, and perfect practicability. Substitution (substituting one substance for another substance (mostly the strong one replaces the weak one)) has replaced the older generation of lever-type wrenches, and then becomes faulty. Although hydraulic wrenches are small in size, their structure is very simple. Therefore, as long as the material (Material) is excellent, the probability of a problem (probability) is very low, and it has been investigated. At present, the quality of Chinese-made hydraulic wrenches cannot be compared with those of developed countries. The main difference is that, apart from technical aspects, some semi-finished materials cannot be independently produced in China (Produce), such as particularly high-strength (strength) seals Rings, high-strength joints, and the high-strength materials of the hydraulic wrench itself are difficult to produce with the current domestic technology, or the cost is extremely high, so they can only rely on imports.
