Low-pressure Variable Vane Pumps VHO series

Welcome to "Saar Hydraulic", your one-stop hydraulics resource.

Features: VHO only for the needs of the hydraulic oil and the circuit design.2, low variable vane pump circuit VHO can improve efficiency, lower noise, lower oil temperature, so that the input of energy into effective power, to achieve power savings purposes.3, low variable vane pump VHO for grinding machines, automatic lathes, machine tools, shoe machinery, and various other special machines or single-energy machine. MODEL NUMBER DESIGNATON VHO-F-15-A2 ① ② ③ ④ ① serial number Serial Nunber② assembly type Assemble model L: Foot Foot Type F: Flange Frange Type③ discharge quantity Delivery capacity④ pressure adjustment range Range of Adjusting A1: 15-70 kg / cm ² A2: 70-140 kg / cm ² Instructions of usage: 1, the general variable vane pump in a closed circuit VHO prevail.2, the motor shaft axis with variable vane pump VHO using coupling assembly, balance need 0.05.mm error less than the angle error to be within 1 °.3, install variable vane pump suction oil filter is recommended when VHO 100 to 150 mesh, diameter depending on the actual VHO variable vane pump discharge amount may be, the assembly shall be higher than the bottom of the tank 5 to 10 cm.4, Recommended hydraulic oil are: a, variable vane pump VHO Working pressure below 70KG/cm ², the hydraulic oil viscosity 30 ~ 50cts (ISO VG32) is more suitable working conditions. b, variable vane pump working pressure is higher than VHO 70KG/cm ², the hydraulic oil viscosity 50 ~ 70cts (ISO VG32) is more suitable working conditions.5, the variable vane pump VHO continuous operating temperature of the hydraulic oil used should be maintained at 30 ~ 60 ℃, below 15 ℃, please use the heater, more than 60 ℃, please use the cooler.6, to reduce inhalation resistance, variable inlet vane pump VHO Do not be too high oil surface one meter.7, start the variable vane pump VHO, first note that the electric motor with variable vane pump VHO should turn in the same direction, so that the motor rotates slowly segmented pressure until desired pressure.

Double vane pump works: it consists of stator, rotor, blade and oil pan and other components. The inner wall of the stator is approximately elliptical. The blade is mounted in the radial groove of the rotor and slides along the groove, and the rotor is mounted concentrically with the stator. When the rotor is rotated, the blade is pressed against the inner surface of the stator under the action of centrifugal force, and is forced to reciprocate in the rotor tank with the change of the inner surface curve of the stator, and the sealing working chamber between adjacent two blades is enlarged and shrunk Variety. When the blade is slid from a small radius arc to a large radius arc, the sealed working chamber gradually increases to form a local vacuum, and the oil in the tank is sucked through the oil suction chamber through the oil pan; Rotate the rotor every week, the blade in the tank to slip back and forth 2 times to complete the 2 oil and 2 times the pressure oil, and the pressure generated by the radial force is balanced, so called double acting, also known as balanced.
Single acting vane pump works: mainly by the stator, rotor, blade and oil pan and other components. The inner surface of the stator is a cylindrical shape, the rotor is eccentrically mounted in the stator, that is, an eccentric e, the blade is mounted in the rotor radial chute and slid radially within the slot. Rotor rotation, the centrifugal force and the role of the root pressure of the blade under the action of the blade close to the inner surface of the stator, so that between the two adjacent leaves to form a sealed working chamber. In one side, the blade gradually extended, sealed working chamber gradually increased, the formation of local vacuum, the formation of oil; the other hand, the other side, the formation of oil. Rotate each turn a week, the blade in the chute reciprocating slip 1 times to complete a suction oil pressure. Oil pressure generated by the radial force is not balanced, so called single acting, also known as unbalanced vane pump.
