Structural features of Rexroth vane pumps and common models of Rexroth PV7

Thread Content

All Rexroth vane pumps are centrifugal pumps with a horizontal design and a single pump casing. A special clamp is used to secure the pump body and the pump cover, allowing the outlet direction of the pump to be set at any position within 360 degrees, which facilitates installation and use. The bearing assembly of the sand pump features a cylindrical structure, which facilitates adjusting the gap between the impeller and the pump body; it can be removed as a whole during maintenance. The bearings are lubricated with grease. The shaft seal types for sand pumps include packing seals, impeller seals, and mechanical seals. The sand pump features a wide flow channel, good cavitation resistance, high efficiency, and corrosion resistance. The main transmission methods include V-belt drive, elastic coupling drive, gear reduction box drive, hydraulic coupler drive, variable frequency drive units, and thyristor speed control. The material of the overcurrent components is high-hardness wear-resistant alloy cast iron. Multiple speeds and various variations are employed to ensure the pump operates under optimal conditions. It has a long service life and high operational efficiency, and can meet various harsh conveying conditions. REXROTH vane pumps are primarily used for the continuous transport of highly abrasive materials whose particles are too large for conventional slurry pumps to handle. Suitable for dredging, sand and gravel suction, river dredging, mining, and the transportation of slag from metal smelting processes. Before a REXROTH vane pump starts operating, the pump must first be filled with liquid. Once the centrifugal pump is started, the impeller rotates rapidly; the blades on the impeller drive the liquid to move. As the liquid moves, it flows toward the outer edge of the impeller due to inertia. At the same time, the impeller draws in liquid from the suction chamber. During this process, the liquid flows around the blades, and as it does so, it exerts an upward force on the blades. In turn, the blades exert a force on the liquid that is equal in magnitude but opposite in direction to this upward force. This force does work on the liquid, giving it energy so that it can flow out of the impeller. As a result, both the kinetic energy and pressure energy of the liquid increase. The REXROTH vane pump transfers the mechanical energy of the prime mover to the liquid by means of the action of the rotating impeller on the liquid. Due to the action of the centrifugal pump, as the liquid flows from the inlet to the outlet of the impeller, both its kinetic energy and pressure energy increase. The liquid discharged by the impeller passes through the discharge chamber, where most of its kinetic energy is converted into pressure energy; this pressurized liquid is then sent along the discharge pipeline. At the same time, a vacuum or low pressure is created at the impeller’s inlet as a result of the liquid being discharged. Under the effect of the surface pressure (atmospheric pressure) in the liquid reservoir, the liquid is forced into the impeller’s inlet. Thus, the rotating impeller continuously draws in and discharges liquid. The REXROTH vane pump is the most widely used water pump in agriculture due to its simple structure, ease of use and maintenance, and high efficiency; however, it can be a major source of frustration when it fails to lift water. Now, the issue is that water cannot be pumped up.
