Today, the development of the machinery industry is getting ahead, while the hydraulic industry also will be vacated born. Hydraulic power element is a hydraulic system, its role is the original motivation of the mechanical energy into fluid pressure energy, refers to the hydraulic system of pumps refinement pump (import), which provides power to the entire hydraulic system. The general structure hydraulic gear pumps, vane pumps and piston pumps. By Cipian introduction, makes you a better understanding of the hydraulic pump. The composition consists of hydraulic pump couplings, hydraulic tank and oil filters of three parts. Couplings: hydraulic pump drive shaft can bear radial and axial forces, and therefore does not allow direct installation of pulleys, gears, sprockets maintenance pump (import) phones in the shaft, drive shaft and coupling connection usually pump drive shaft. As a result of manufacturing reasons, pump and coupling coaxial exceeded, assembly time and there is a deviation, the pump speed is increased with the increased centrifugal force coupling deformation, deformation big centrifugal force increased. Resulting in a vicious cycle, and the results generated noise and vibration, thus affecting the life of the pump. In addition, such as loose coupling stud fastening is not timely, not timely replacement of worn rubber rings and other factors. Hydraulic Tank: The main role of the hydraulic oil tank in the hydraulic system for the oil, cooling, separation of oil contained in the air and eliminate bubbles. We must first consider their choice of tank capacity hydraulic pump, general mobile device to take two to three times the maximum pump flow rate, fixed equipment to take 3 to 4 times; Second, consider the oil tank, when the entire hydraulic system extends the oil tank shall not be less than the minimum oil level, when the cylinder is retracted after the oil shall not exceed the maximum oil level; final consideration tank structure, partitions inside the tank and tradition can not play the role of precipitation dirt, install a vertical interval along the longitudinal axis of the tank board. Leave gaps between the separator end plate at one end and the fuel tank communicates with the space on both sides of the separator, the hydraulic pump disposed at one end of the oil inlet and outlet sides of the separator is not communicating, and back into the oil so that the distance between the farthest specializing oil pump (imported), hydraulic tank more than some cooling effect. Filter: Pollutants 10μm particle size generally less affected by the pump is not obvious, but greater than 10μm, the service life of the pump there is a significant effect especially at 40μm or more. Solid particle contamination of hydraulic oil pump is relatively easy to make the surface of the moving parts wear and tear, for which you need to install filters to reduce the degree of contamination of the oil. Filter precision: axial piston pump 10 ~ 15μm, vane pump for 25μm, gear pumps for 40μm. Contamination wear of the pump can be controlled within the allowable range. .
