Embodiment Construction

[0018] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but the protection scope of the present invention is not limited thereto.

[0019] The novel double-suction swirl pump of the present invention is installed to work underwater, and the water pump is installed on the support of the platform through the bearing body support. The position of the new double-suction swirl pump on the underwater platform makes the water outlet tightly connected with the pipeline.

[0020] Such as figure 1 As shown, the novel double-suction swirl pump includes a double-suction impeller 3, a main shaft 15, a front cover 2, a pump body 4, a packing chamber 66, a bearing body upper bracket 7, a right bearing gland 8, a wear plate 9, a packing Gland 10, bearing body 11, bearing body lower bracket 12, the main shaft 15 is assembled on the bearing body 11, one end of the main shaft 15 is connected with the motor, and the dou...

Abstract

The invention provides a novel double-suction vortex pump. The novel double-suction vortex pump is characterized in that a double-suction impeller is eccentrically arranged relative to a cavity of a pump body by 8 mm to 15 mm; blades of the double-suction impeller comprise the long blades and the short blades, wherein the long blades and the short blades are different in length and the length L1 of each short blade is 2/5 to 3/5 of the length L2 of each long blade; the width b2, occupied in the cavity of the pump body, of each blade of the double-section impeller is 1/4 to 1/3 of the width b1 of the corresponding blade. The double-suction impeller and the pump body are eccentrically arranged so that force exerted on the double-suction impeller by fluid can be better balanced when the double-suction impeller is operated; the long blades and the short blades different in size are designed in a matched mode so that the problem that fluid channels among the blades are blocked by solid particles can be well solved; compared with a traditional vortex pump, efficiency of the double-suction vortex pump is improved to a certain degree, operation is more stable, and the overall performance is improved. The problem that the traditional vortex pump is low in efficiency is solved and the original characteristic of the vortex pump is kept.

Description

technical field [0001] The invention designs a novel double-suction swirl pump. Background technique [0002] Double-suction swirl pumps are mostly used to pump complex media or fluids containing impurities, such as two-phase fluids containing garbage, short fiber materials or feces, but at the same time it also ensures the efficiency of the pump, the pump has good suction performance, and has good anti-cavitation performance , can pump liquids with high gas content, and can also pump high-concentration fluids. Compared with other impurity pumps, the swirl pump has good non-clogging performance, and can pass solid particles that are about the same diameter as the pump outlet. It is destructive, the axial clearance between the impeller and the pump body is not as sensitive to the performance of the pump as the centrifugal pump, and no clearance adjustment is required. Most of the impellers of swirl pumps are open radial impellers, the manufacturing process is simple, and the...
