Product Details

The main structural differences between vane motors and vane pumps are: 

(1) Motors must have aane pressing mechanism to ensure that the vanes are in tight contact with the inner surface of the stator before startup, otherwise, they cannot start. 

(2) Pumps only need to rotate in one direction, while motors need to rotate both forward and backward. 

Therefore, the vanes of the motor are all radially, with symmetrical top ends; the two main oil ports have the same diameter; the oil drainage for bearing lubrication has a separate oil return pipe when necessaryfor motors specifically used in lifting mechanisms, the oil drainage from the bearings can be internally connected to a fixed low-pressure chamber; the vane roots can communicate with pressure oil chamber regardless of whether the motor is rotating forward or backward. After equipping a multi-acting vane motor with a shift valve, it can manually automatically change the number of effective working chambers based on working pressure, i.e., let one or several pairs of inlet and outlet oil chambers communicate with each other without oil supply, so there is no oil pressure difference between them and no torque is generated, thus becoming a step-variable motor with variable displacement. When the three- motor becomes single or double-acting, the radial forces are unbalanced, so it is only suitable for low pressure; when the medium and high-pressure vane are variable, they should always maintain radial force balance, and are often made into four or six-acting motors. 

The vane pressing mechanisms commonly used in v motors are as follows:

(1) Straight rod mechanism--At the bottom of each pair of vanes in relative positions around the circumference, two straight rods passing the rotor axis are used to maintain the seal between the vanes and the stator surface, while introducing the working oil from the pressure side into the small oil at the bottom of each vane to help press the vanes outward. In bidirectional motors, the oil passages to the vane bottoms are equipped with shuttle to ensure that the working oil from the pressure side can be introduced to the vane bottoms whether rotating forward or backward. 

(2) Arcuate rod--Severaluate rod grooves are opened on the two end faces of the rotor, with the intersecting parts of each pair of arcuate rods having a reduced cross-section and drill holes at both ends of the rods, with compensation springs inside, to press the vanes against the stator surface. 

(3) Rocker arm rod--Rocker arms are installed on both end faces of the rotor, which maintain the initial seal of each pair of vanes through rods and compensation springs. 

(4) Springs are set at the bottom of the vanes. 

Compared with plunger motors, vane motors have a simpler structure and the lightest weight per displacement, but their volumetric efficiency is lower, and they are only suitable for medium and low pressures. Moreover, the friction between the vane tips and the surface of the stator is relatively high, resulting in lower mechanical efficiency and starting efficiency, and poorer low-speed stability
