Abstract
This invention relates to a sugar liquor pump characterizing in including a pump, a main shaft, a supporting piece, a coupling, impellers composed of a suction impeller and a spit out impeller arrayed oppositely, the suction ports are symmetrically mounted against the sealed chamber. Since the suction impeller and the spit out one are arrayed oppositely, the two axial forces generated when the pump is working are counteracted and there is not axial force or leakage, secondly, the impellers face the mechanical sealed chamber, the input liquor is absorbed by the impeller and the sealing is not forced by outside pressure, besides, there is an output path at the top of the suction channel, liquor is output in collection.
Description
Technical field
The present invention relates to the sirup pump in a kind of sugar mill.
Background technique
The TKG series sirup pump that use in existing sugar refinery is single-stage energy absorbing bracket formula centrifugal pump.Impeller is open, and the gap between impeller and the pump inner cap must be controlled within limits, just can reach the design usability.The axial force of the on-stream generation of water pump is to bear (universal principle of one step single sucking pump) by the dish of two on carriage bearing.The disadvantage of this structure is: if bearing is unable to bear the load of axial force, must cause the heel and toe wear of component, the utilization efficiency and the life-span of having reduced water pump.Under the double action of axial force and pump chamber delivery pressure, mechanical seal is leaked, consequently the loss of the rising of cost of production and output.
Summary of the invention
The objective of the invention is to overcome the defective of prior art, a kind of axial force that do not have is provided, utilization efficiency height, long, leak free novel sirup pump of life-span.
Technological scheme of the present invention is: sirup pump comprises the pump housing, main shaft, supporting member (bearing and bearing support and bearing cap), coupling, impeller, it is characterized in that impeller is made of the intake impeller and the impeller that spues, intake impeller is relative with the impeller that spues to be arranged, and suction port is all installed in the face of the closed chamber symmetry.
Sirup pump of the present invention does not have axial force, do not have to leak, owing to arrange intake impeller is relative with the impeller that spues, two axial forces that produce when making pump working are cancelled out each other, and reach the purpose of no axial force.Meanwhile, all siphoned away, make mechanical seal not be subjected to pressure outside, play lubricated and cooling effect by external cooling water, thereby prolonged the working life of mechanical seal, reach leak free purpose by impeller because impeller face, is imported liquid to the mechanical seal chamber.Secondly, the output road is arranged, make liquid concentrate output, reduce flow loss, improved the efficient of water pump at suction casing runner top.This pump structure compactness, easy accessibility, two ends all can freely be dismantled.

Embodiment
Below in conjunction with accompanying drawing the present invention is done further auspicious stating, but be not limited to shown in the accompanying drawing.As shown in Figure 1, the present invention is made up of parts such as the pump housing, main shaft, bearing and bearing support and bearing cap, coupling, impellers, impeller is made up of the intake impeller and the impeller that spues, and intake impeller is relative with the impeller that spues to be arranged, and suction port is all installed in the face of the symmetric figure of closed chamber.The intake impeller 11 and the impeller 15 relative arrangements that spue, suction port are all in the face of closed chamber, and two impellers are isolated by intermediate clapboard and middle cover, and two closed chambers are all adorned a stuffing box gland with the enhanced leaktightness effect.Cooling chamber outside closed chamber and bearing chamber with external water source cool off, lubricating mechanical sealing chamber and bearing chamber, to reduce the heat of syrup temperature transfer.Be provided with output channel in suction casing, enter the impeller that spues through the intermediate clapboard passage, purpose is to concentrate liquid, reduces flow loss.Since there has not been axial force, the water pump operation balance, and safe and reliable, noise is low, vibration is little, even if the empty wagons operation does not have mechanical wear yet.
Claims (2)
1. a sirup pump is characterized in that comprising the pump housing, main shaft, supporting member, coupling, impeller, it is characterized in that impeller is made of the intake impeller and the impeller that spues, and intake impeller is relative with the impeller that spues to be arranged, and suction port is all installed in the face of the closed chamber symmetry.
2. sirup pump according to claim 1 is characterized in that intake impeller and spues being provided with intermediate clapboard and middle cover between the impeller.
