Vickers piston pump is a straight-axis variable pump with 9 specifications, which relies on pressure and / to control the variable. A variety of control options are available, providing maximum working flexibility. or flow compensator. Vickers piston pumps operate quietly and meet today's demanding industrial conditions. The noise level of each pump is close to or lower than that of the motor driving the pump. The noise is reduced by a patented timing configuration that also results in very small pressure "pulsations" in the output flow. This allows the noise in systems using PVQ plunger pumps to be reduced as well.
Vickers series plunger pumps can work with various types of hydraulic fluids. In addition to typical petroleum-based hydraulic oils and synthetic hydraulic oils, it can also be adapted to aqueous hydraulic fluids and phosphatidic acid hydraulic fluids.
Vickers piston pumps have a through-shaft drive solution to adapt to multiple pump applications and installation needs. The through-shaft drive pump can be equipped with various types of fixed pumps and variable displacement pumps of different specifications, forming a compact and flexible assembly. Such an assembly is less expensive to set up because the size of the unit is reduced and only a single mount on the prime mover is required.
Vickers piston pumps have excellent operating characteristics, and a wide range of control methods and installation forms allow the most suitable model to be selected for any application. Furthermore, the durability and long life characteristics of PVQ piston pumps are comparable to the best industrial products on the market today. For 75 years, the Eaton name has been synonymous with long, trouble-free work. Structure
●The ability to achieve high working pressure in a compact size ensures a high power-to-weight ratio and reduced installation costs.
●The inherent low-noise characteristics of the mother-and-daughter blade mechanism improves operator comfort.
●The 12-blade system ensures small amplitude of flow pulsation and low system noise characteristics.
●Hydraulic balancing designed to prevent internally induced radial loads on the shaft and bearings ensures long life.
●Twin pump and through-shaft drive configurations save installation space and cost by eliminating twin-shaft motors or by reducing the number of motors and
●drive couplings. ●Through-axis drive type provides valuable loop design flexibility, such as quantitative and variable types on a single input drive.
●16 flow capacities and the ability to achieve high operating pressures provide optimal choice and single-source capability for the entire range of your flow and pressure requirements.
●Factory-tested movement kit provides new pump performance after installation.
●The movement kit structure ensures rapid and efficient on-site repairability. The movement and the drive shaft are separated, and the flow capacity and operation can be easily changed without folding the pump from its base
●The oil inlet and outlet can be oriented in four different ways to each other The relative position provides great installation flexibility and facilitates machine design. [title2]Key points of management of vane pumps[/title2] A vane pump is a pump in which the vanes in the rotor slot are in contact with the pump casing (stator ring), and the sucked liquid is pressed from the inlet side to the discharge side.
Performance
In addition to preventing dry running and overloading, preventing air suction and excessive suction vacuum, the management points of the vane pump should also pay attention to: If the pump direction changes, its suction and discharge will The direction also changes. The vane pump has a prescribed steering direction and reverse direction is not allowed. Because the rotor blade grooves are inclined and the blades are chamfered, the bottom of the blades are connected to the oil discharge chamber, and the throttling grooves and suction and discharge ports on the oil distribution plate are designed according to the established steering direction. Small pump-0.015~0.03mm Medium pump-0.02~0.045mm The temperature and viscosity of the oil should generally not exceed 55°C, and the viscosity is required to be between 17~37mm2/s. If the viscosity is too high, it will be difficult to absorb oil; if the viscosity is too small, leakage will be serious. Reversible vane pumps must be specially designed. The vane pump assembly oil distribution plate and stator must be correctly positioned with positioning pins. The blades, rotor, and oil distribution plate must not be installed backwards. The suction area on the inner surface of the stator is most susceptible to wear. If necessary, it can be installed overturned to change the original suction area. Continued use for discharge area.
When disassembling and assembling, pay attention to the cleanness of the working surface and the oil should be well filtered during work. If the gap between the blades in the blade groove is too large, leakage will increase; if it is too small, the blades will not be able to expand and contract freely, which will lead to malfunction. The axial clearance of the vane pump has a great influence on etav. [title] Vickers vane pump commonly used series[/title] 20V vane pump series
