Vane Pump Rexroth HENGTE Brand

Essentially, sand pump is just a general term. Generally, it is mainly used in industries such as mining, coal, metallurgy, chemical engineering, and environmental protection. The general meaning of sand pumps refers to the use in industries such as environmental protection, sand excavation, and river dredging. This series of sand pumps mainly features ES or G series. In addition, there are many types of sand pumps called SB sand pumps in the petroleum industry, PS sand pump series in the mining industry, and so on. The sand pump introduced in this article mainly refers to the ES or G series sand digging pumps commonly used in the environmental protection industry.

REXROTH vane pumps are all horizontal, single casing centrifugal pumps. Special clamps are used to clamp the pump body and cover, and the discharge direction of the pump can be at any position of 360 degrees, making installation and use convenient. The bearing components of the sand pump adopt a cylindrical structure, which is convenient for adjusting the gap between the impeller and the pump body. They can be removed as a whole during maintenance. 

The bearings are lubricated with grease. The shaft seal forms of sand pumps include packing seal, auxiliary impeller seal, and mechanical seal. The sand pump has a wide flow channel, good cavitation performance, high efficiency, and wear resistance. The main transmission methods include V-belt transmission, elastic coupling transmission, wheel reducer transmission, hydraulic coupling transmission, variable frequency drive device, thyristor speed control, etc. The material of the overcurrent component is made of wear-resistant alloy cast iron with high hardness.

Adopting multiple speeds and variants to ensure the pump operates under optimal operating conditions. Long service life, high operating efficiency, and able to meet various harsh conveying conditions.

REXROTH vane pump is mainly used for continuous transportation of highly abrasive materials that cannot be transported by general slurry pumps due to their large particle size. Suitable for dredging, sand and gravel suction, river dredging, mining, and metal smelting slag transportation. Before working, the REXROTH vane pump first fills the pump with liquid, and then starts the centrifugal pump. The impeller rotates rapidly, and the blades of the impeller drive the liquid to rotate. When the liquid rotates, it relies on inertia to flow towards the outer edge of the impeller. 

At the same time, the impeller sucks in liquid from the suction chamber. During this process, the liquid in the impeller flows around the blades. During the flow around the blades, the liquid acts as a lift force on the blades, and in turn, the blades have a lift force equal to this force A force in the opposite direction is applied to the liquid, which does work on the liquid, causing it to receive energy and flow out of the impeller. At this time, the kinetic energy and pressure energy of the liquid increase.

The REXROTH vane pump relies on the action of the rotating impeller on the liquid to transfer the mechanical energy of the prime mover to the liquid. Due to the action of a centrifugal pump, the velocity energy and pressure energy of the liquid flow from the impeller inlet to the outlet increase. The liquid discharged by the impeller passes through the pressure chamber, and most of the velocity energy is converted into pressure energy, which is then transported out along the discharge pipeline. At this time, a vacuum or low pressure is formed at the inlet of the impeller due to the discharge of the liquid. The liquid in the suction pool is pressed into the inlet of the impeller under the action of the liquid level pressure (atmospheric pressure), The rotating impeller continuously sucks in and discharges liquid.
