Centrifugal impeller centrifugal pump impeller is a key component. (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, D6-25x9 mining multi-stage pump, low efficiency of such pumps. Closed and semi-closed impeller in operation, leaving a portion of the impeller into the high-pressure liquid can leak between the impeller and the pump housing cavity, Runan mining multi-stage pump, because the front wheel low pressure liquid suction port, 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, can reduce the pressure on both sides of impeller poor, D6-25x10 mining multi-stage pump, thereby reducing the adverse effects of axial thrust, but also reduces the efficiency of the pump. These holes are called balance hole. (2) by pipette in different ways can be divided into simple single suction impeller with two double-suction, 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, D6-25x11 mining multi-stage pump, can be divided into backward curved blade, radial and bending forward three, since the rear curved blades in favor of the kinetic energy of the liquid is converted into static pressure It can, therefore are widely used. Energy loss due to the impact of the guide wheel when D46-30X7D46-30X8D46-30X9D46-30X10D46-50X3D46-50X4D46-50X5D46-50X6D46-50X7D46-50X8D46-50X9D46-50X10D46-50X11 centrifugal impeller to reduce the departure liquid directly into the pump casing caused In sometimes means a stationary between the impeller and the pump housing and with a blade guide wheel. Guide vane wheel liquid entering the pump casing and turning to the continuous expansion of the flow channel, so that part of the kinetic energy is efficiently converted to static pressure energy. Multistage centrifugal pump usually are installed guide wheel. Snail-shaped casing, backward curved impeller blades and guide wheel can improve the conversion of kinetic energy to static pressure ratio, it can be regarded as energy transfer devices.
