Abstract

The utility model discloses a double suction high-efficiency lower pulse malposed impeller, comprising an impeller main body (1), a right inlet (6), a left inlet (5) and an outlet, wherein a separator (3) is radially arranged in the middle of the impeller main body (1) and separates the outlet into a right outlet (4) and a left outlet (2) respectively communicated with the right inlet (6) and the left inlet (5) and the right inlet (6), the left inlet (5), the right outlet (4) and the left outlet (2) are malposed. The loss of the pump due to the water power impact is reduced, the water pulse is reduced, the pump efficiency is increased and the vibration noise of the pump is reduced.

Description

The efficiently low pulse dislocation of a kind of double suction impeller

Technical field

The utility model relates to a kind of impeller, particularly relates to the efficiently low pulse dislocation of a kind of double suction impeller.

Background technique

The structure of the impeller in the double sucting pump is to be provided with right import and left import on impeller bodies, the centre is provided with the same outlet that is communicated with right import and left import, Fig. 5 is a double suction pump blade wheel structure schematic representation, because the water inlet of impeller both sides does not separate in the outlet port, easily produce the loss of waterpower bump at impeller outlet place both sides current, influence the efficient of water pump, cause the water pump vibration and noise.

The model utility content

Technical problem to be solved in the utility model provides a kind of waterpower bump loss that reduces pump, reduces the pulse of water, improves the efficient of pump, reduces the efficiently low pulse dislocation of the double suction impeller of the vibration noise of pump.

In order to solve the problems of the technologies described above, the efficiently low pulse dislocation of the double suction that the utility model provides impeller, comprise impeller bodies, right import, left import and outlet, intermediate radial in described impeller bodies is provided with dividing plate, described dividing plate is separated into right side outlet and the left side outlet that is communicated with described right import and described left import respectively with described outlet, and described right import exports with a described left side and shifts to install respectively with described left import, described right outlet.

Described right import and described left import, described right outlet and described left side outlet 36 ° of settings of mutual dislocation respectively.

Adopt the efficiently low pulse dislocation of the double suction impeller of technique scheme, because by the dislocation of impeller both sides water inlet blade is arranged, dividing plate is set between the blade of both sides cleverly, the water outlet of impeller both sides is separated by dividing plate, the waterpower bump that reduces to pool together after the water inlet of impeller both sides is done work by impeller loses, reduced the pulse of water simultaneously, owing to reduced the waterpower bump loss of pump, effectively raise the efficient of pump, owing to reduced the pulse of water, make pump operation more steady, vibration noise is lower.With respect to conventional middle-opening pump impeller relatively, its efficient is high by 5%～10% usually, and its noise hangs down 3dB～5dB.

Double suction misplaces impeller owing to reduced the waterpower bump loss of pump with efficient low arteries and veins, reduced the pulse of water, improved the efficient of pump, reduced the vibration noise of pump, this kind impeller is particularly suitable for the middle-opening pump of middle and high lift, be particularly suitable for the water pump transformation, improve the efficient of pump, energy-conservation place.

In sum, the utility model is a kind of waterpower bump loss that reduces pump, reduces the pulse of water, improves the efficient of pump, reduces the efficiently low pulse dislocation of the double suction impeller of the vibration noise of pump.

Embodiment

The utility model is described in further detail below in conjunction with the drawings and specific embodiments.

Referring to Fig. 1, Fig. 2, Fig. 3 and Fig. 4, intermediate radial in impeller bodies 1 is provided with dividing plate 3, dividing plate 3 is separated into right outlet 4 and left side outlet 2 with outlet, right outlet 4 is communicated with right import 6, left side outlet 2 is communicated with left import 5, right import 6 and left import 5, right outlet 4 and left side outlet 2 36 ° of settings of mutual dislocation respectively.

Referring to Fig. 5, the double suction pump impeller easily produces the loss of waterpower bump because the water inlet of impeller both sides does not separate in the outlet port at impeller outlet place both sides current, influences the efficient of water pump, causes the water pump vibration and noise.Referring to Fig. 1, Fig. 2, Fig. 3 and Fig. 4, because the dislocation to impeller both sides water inlet blade is arranged, dividing plate 3 is set between the blade of both sides cleverly, with the water outlet of impeller both sides separately, reduces the waterpower bump loss that pools together after the water inlet of impeller both sides is done work by impeller by dividing plate 3, reduced the pulse of water simultaneously, owing to reduced the waterpower bump loss of pump, effectively raised the efficient of pump, owing to reduced the pulse of water, make pump operation more steady, vibration noise is lower.With respect to conventional middle-opening pump impeller relatively, its efficient is high by 5%～10% usually, and its noise hangs down 3dB～5dB.
