Advantages and disadvantages of hydraulic tools

Hydraulic tools are the organic combination of hydraulic systems and ordinary tools into a whole. Convert powerful hydraulic power into mechanical movements such as reciprocating linear motion, rotational motion, and cycloidal motion. A complete hydraulic tool system consists of five parts, namely power components, execution components, control components, auxiliary components, and hydraulic oil. Hydraulic tools include: hydraulic wrench, electric pump for hydraulic wrench, hydraulic jack, hydraulic bolt tensioner, hydraulic flange separator, hydraulic nut cutter, hydraulic puller, etc. Hydraulic tools have the advantages of high efficiency and convenience.

Advantages: 1. Mineral oil is generally used as the working medium, and the relative moving surface can self lubricate, with a long service life. 2. Lightweight, small in size, small in motion inertia, and fast in reaction speed. 3. The various components of hydraulic transmission can be conveniently and flexibly arranged according to needs. 4. It can automatically achieve overload protection. 5. Convenient operation and control, capable of achieving a wide range of stepless speed regulation (with a speed range of 2000:1). 6. It is easy to achieve linear motion. 7. It is easy to achieve machine automation. When using electro-hydraulic joint control, not only can a higher degree of automatic control process be achieved, but also remote control can be achieved.

Disadvantages: 1. Easy to leak. The hydraulic system has a high oil pressure, and hydraulic oil is prone to leakage through seals or gaps, causing hydraulic medium consumption and environmental pollution. 2. Low transmission efficiency In the process of energy transmission, hydraulic transmission often has more energy loss (pressure loss, flow loss, etc.), which makes the transmission efficiency low 3. The transmission ratio is inaccurate Due to the compressibility of transmission medium, leakage, pipeline elastic deformation and other factors, the hydraulic system cannot strictly guarantee the constant ratio transmission. 4. The viscosity of temperature sensitive oil varies with temperature, causing changes in flow rate, leakage rate, and resistance, which can easily cause unstable movement of the working mechanism. 5. High manufacturing costs require high manufacturing accuracy for hydraulic components in order to reduce leakage, thereby increasing manufacturing costs.
