Cleanliness of hydraulic oil higher, longer pump life A7V78DR2.0LZF00 A7V78DR2.0LZF00 A7V80MA2.0LSF00 A7V160NC2.0RSF00 A7V28EL5.1LSF00 A7V78MA5.1LSF00 A7V250NC5.1RSF00 A7V78DR2.0LZF00 According to information provided by the manufacturer of hydraulic pumps, bearings The average service life of 10000h, this value would need to replace the new port is an important means of hydraulic piston system is better but the quality and stability of the ship in order to ensure the normal navigation or mooring, crew and passengers to meet the daily needs of each Boats should be equipped with a certain amount of, can play a relevant role in marine mining, marine pump is one of the important auxiliary piston with a rated pressure, compact structure, high efficiency and flow and easy adjustment of domestic pump, is Widely used in high pressure, high flow and flow needs to be adjusted occasions, such as hydraulic machines, construction machinery and ships in port plate with flat-screen assignment and spherical assignment in two forms when the plunger by pulling out, the working chamber pressure is reduced, the outlet valve is closed below When the inlet pressure, inlet valve open, the liquid enters; when you push in the plunger chamber pressure increases, the inlet valve closed hydraulic pump sales, higher than the outlet pressure, the outlet valve is opened, the liquid discharge when using the overflow to regulate the pressure and When the flow, there is the balance back to the original part of the overflow system for self-absorbing type piston pump, the hydraulic oil tank must not fall below the lower limit of the oil standard, to maintain a sufficient amount of hydraulic oil A7V58SC5.1LPF00 A7V58SC5.1RPF00 quantitative plunger pump / motor 1) the cylinder axis of the spindle axis at an angle that is constant axial piston pump element bent shaft structure, with a fixed displacement. In the open or closed hydraulic system hydraulic drive to work as a pump or motor condition condition. 2.) When a pump mode, the flow is proportional to the drive speed and displacement. 3) When a motor condition, the output speed is proportional to the input flow. And inversely with displacement. With output torque is proportional to the high side and the low side. 4.) structure of the hydraulic pump repair spherical valve plate, for rotating assembly is good for the features, and speed stability, low noise. 5) As a result of the radial thrust bearing, can withstand the radial load. 6.) comply with ISO standard mounting flange, versatility. 7.) The system uses reasonably clean of anti-Mo, fire resistant hydraulic oil medium, extended service life, increased use of the occasion. Hydraulic oil should be replaced every six months. Output shaft: flat keys, splines are free to choose! Hydraulic pump sales, hydraulic pumps, hydraulic creating crystal grain quality assurance by the Jinan Chong Hydraulic Machinery Limited.
