Learn contrast contrast radial electric pump with axial electric pump and pressure electric pump radial and axial electric pump electric pump: the volumetric efficiency of high radial electric pump electric pump, smooth, flow uniformity DBS electric pump, low noise, working pressure advantages, but the radial electric pump more sensitive to contamination of the hydraulic oil, the structure is more complex, higher cost. The biggest advantage is the axial electric pump: Use less demanding on the hydraulic oil. High pressure electric pump installation sequence is as follows: During the installation of high pressure electric pump electric valve body, in order to prevent debris falling into the machine, all units should cover the hole; the crew buried on anchor bolts on the basis between the base and foundation, with a pair of wedge pad with correction; correction concentric shaft and motor shaft coupling on the outer road, allowable deviation 0.1 mm; two coupling plane gap should ensure that 2 to 4 mm, (a small pump to take a small value) should be uniform gap, 0.3 mm tolerance. Common types of pump: 1, can be adjusted according to whether the flow can be divided into: variable displacement pump and dosing pumps. Output flow can be adjusted as needed is called variable displacement pump, the flow rate can not be adjusted is called a metering pump. 2, according to the hydraulic system commonly used pump structure is divided into: gear pumps, vane pumps and piston pumps three kinds. Gear pumps: smaller, simpler structure, strict requirements for cleanliness DSD electric oil pump, the price is cheaper; but the shaft by the unbalanced force, badly worn, leaking large. Vane pump: divided double acting and single acting vane pump vane pump. The pump flow evenly, smooth operation, low noise, high efficiency for the pressure and volume than the gear pump, complex structure than the gear pump. Piston: high volumetric efficiency, the leak is small, can work under pressure, mostly for high power hydraulic system; but the complex structure, materials and processing high precision, expensive, high oil cleanliness requirements.
