D-type multi-stage centrifugal pump Product Overview: D-type multi-stage centrifugal pump for conveying water and physical and chemical properties similar to water or liquids. The pump head is 19-245.7m, a flow rate of 18 to 162m3 / h. The maximum temperature of the liquid does not exceed 80 ℃, widely used in mining drainage, factories and urban water supply purposes. Physical and chemical properties of liquid water or D-type multi-stage centrifugal pump for conveying solid particles, the temperature is below 80 ℃ similar to water, suitable for mining and urban drainage works of the DF-type pump for transport -20 ℃ ~ 105 ℃, solid particles, liquid, corrosive imported pumps allow pressure 0.6MPa DM-type pump for conveying solid particles content not more than 1.5% neutral mineral water (particle size less than 0.5 mm) and other similar sewage, transmission medium temperature is not greater than 80 ℃, suitable for steel mills, mine drainage, sewage, transportation and other occasions.

(1) according to their mechanical structure can be divided into closed, semi-closed and open three. Closed impeller for conveying the cleaning liquid; semi-closed and open impeller for conveying suspension containing solid particles, D25-30X6 coal mine pump wear, low efficiency of such pumps. Closed and semi-closed impeller in operation, D25-30X5 Mine wear pump impeller left part of high-pressure liquid may leak into the space between the impeller and the pump casing, the front side of the impeller due to the liquid inlet of low pressure, Therefore, the effect of liquids on the front wheel, rear pressure range, it had a point to the inlet side of the impeller axial thrust. The force pushing the inlet side of the impeller to move, causing the impeller and casing wear at the contact, resulting in severe vibration of the pump, disrupting the normal operation of the pump. In the impeller rear panel drill several holes, it can reduce the pressure on both sides of impeller poor, thereby reducing the adverse effects of axial thrust, coal pump wear, but also reduces the efficiency of the pump. These holes are called balance hole. (2) by pipette in different ways can be divided into single-suction impeller and double suction two, D25-30X4 coal mine pump wear, simple single-suction impeller structure, fluid can only be sucked in from the side. Double suction impeller impeller symmetrically from both sides simultaneously sucked liquid, which not only has a large liquid absorption capacity, and essentially eliminate axial thrust. (3) According to the geometry of the impeller blades, the blades can be divided into backbends, radial and bending forward three, since the rear curved blades in favor of converting the kinetic energy of the liquid static pressure energy, and therefore widely used.
