Introduction of HEKVEK Hydraulic Tool
HEKVEK hydraulic tools include: hydraulic wrench, special electric pump for hydraulic wrench, Empek hydraulic jack, hydraulic bolt stretcher, hydraulic flange separator, hydraulic nut breaker, HEKVEK hydraulic rama, etc.
A complete hydraulic tool system consists of five parts, namely, power element, actuator element, control element, auxiliary element and hydraulic oil.
Hydraulic tools have the advantages of high efficiency and convenience.
Auxiliary components include oil tank, oil filter, oil pipe and pipe joint, sealing ring, pressure gauge, oil level oil thermometer, etc. Hydraulic oil is the working medium of transmitting energy in the hydraulic system. There are many kinds of mineral oil, emulsifier and synthetic hydraulic oil.
Advantages of HEKVEK Hydraulic Tools:
1. Mineral oil is generally used as working medium. The relative moving surface can lubricate itself and has a long service life.
2. Light weight, small volume, small inertia and fast reaction speed.
3. Various components of hydraulic transmission can be arranged conveniently and flexibly according to need.
4. Overload protection can be realized automatically.
5. It is easy to operate and control, and can realize stepless speed regulation in a wide range (speed regulation range up to 2000:1).
6. It is easy to realize linear motion.
7. It is easy to realize the automation of the machine. When combined electro-hydraulic control is adopted, not only a higher degree of automatic control process can be realized, but also remote control can be realized.
Disadvantages of HEKVEK Tool:
(1) Hekvek is easy to leak. Hydraulic system has high oil pressure, and hydraulic oil is easy to leak through sealing or clearance, which causes hydraulic medium consumption and environmental pollution.
(2) In the process of energy transmission, hydraulic transmission with low transmission efficiency often has more energy loss (pressure loss and flow loss, etc.), which makes the transmission efficiency lower.
(3) The transmission ratio is inaccurate because of the compressibility of the transmission medium, leakage and elastic deformation of the pipeline and other factors, the hydraulic system can not strictly guarantee the fixed-ratio transmission.
(4) The viscosity of temperature-sensitive oil varies with temperature. The change of viscosity causes the change of flow rate, leakage and resistance, and easily causes the unstable movement of working mechanism.
(5)The manufacturing cost is high. In order to reduce leakage, the manufacturing accuracy of hydraulic components is required to be high, which increases the manufacturing cost.
