Vane-type hydraulic motor, small size, low inertia, quick action can be applied to high frequency commutation occasions; but the leak is large, low-speed operation unstable. Therefore vane hydraulic motor is generally used for high speed and torque requirements of small and motion sensitive occasions. Hydraulic motor, also known as motor oil, mainly used in injection molding machinery, ships, from Jan machines, construction machinery, construction machinery, mining machinery, mining machinery, metallurgical machinery, shipbuilding, machinery, petrochemicals, port machinery. 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 of the hydraulic pump refinement, so do not allow direct mounting pulleys, gears, sprockets at the end of the shaft, usually the drive shaft and the pump drive shaft coupling axis. As a result of manufacturing reasons, pump and hydraulic couplings coaxial excessive maintenance calls, 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. Furthermore pump agency, as well 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 the choice of fuel tank capacity, 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 systems are all hydraulic oil tank shall not extend low in 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 bulkhead along the longitudinal axis of the tank. Leave gaps communicating the space on both sides of the separator the separator between one end of the hydraulic pump and the fuel tank of the end plate, the hydraulic pump disposed at one end of the oil inlet and outlet sides of the separator is not communicating, so that oil into the oil and the distance between the back far more than some of the hydraulic tank 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. .
