　　What are the precautions for the use of hydraulic wrenches

　　In many cases, it needs to be applied to hydraulic wrenches. Unlike ordinary wrenches, hydraulic wrenches require more maintenance and maintenance when they are used, because hydraulic wrenches are more expensive and have a wider range of applications (fàn wéi) , If careless maintenance and maintenance during use will seriously damage the hydraulic wrench, its performance and efficacy will not be able to perform normally (showing its inherent ability). What are the attention items when using hydraulic wrenches?

　　First, the hydraulic wrench should be coated with lubricating oil when in use, mainly to minimize friction and ensure the flexibility of the hydraulic wrench components. When applying lubricating oil, you must choose (xuanze) high-quality disulfide (chemical symbol: S) molybdenum (molybdenum), professional lubricating oil can better protect the effect.

　　Second, the sealing and cleaning of the oil cylinder. The oil cylinder is the most important part of the hydraulic wrench. When a leakage condition (Condition) is found in the oil cylinder, it should be disassembled, and the sealing ring should be carefully inspected to see if it is in good condition. A basic type of component failure), it should be removed for replacement. In order to prevent the oil cylinder from being blocked, it should be cleaned regularly to clean out the impurities in the oil cylinder to prevent small substances from clogging the parts.

　　Third, the overall cleaning of the hydraulic wrench, you can choose (xuanze) to use clean water when cleaning, if there are stubborn stains, you also need to use a non-corrosive and aggressive solvent (Properties: transparent, colorless liquid) Wash it and dry it with a soft towel after washing. 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.

　　Many people ask whether hydraulic wrenches are expensive or not. The price of different types of hydraulic wrenches will of course be different. Regardless of its value, you need to find out these attention items and do Good daily maintenance work.
