Abstract
The lining self-sucking pump is a corrosion-resistant centrifugal pump, is suitable for conveying corrosive medium in chemical industry, light industry, smelting industry and other industries, and belongs to the field of industrial pump technology. The pump has the technical key points that a volute is arranged in a pump shell, a liquid storage cavity is formed between the volute and the pump shell, an impeller is in threaded connection with a pump shaft, all overflowing parts of the pump, which are in contact with a medium, are lined with a layer of fluoroplastic or fluoroplastic alloy, when the lining self-priming pump starts to work, liquid in the liquid storage cavity and the impeller chamber is discharged firstly, negative pressure is formed in the volute, and the liquid is sucked into a water inlet pipe and the volute under the action of the negative pressure, so that the purpose of self-priming operation is achieved.
Description
The utility model relates to industrial corrosion protection pumps such as chemical industry, light industry, smelting, belongs to the industrial pump technical field.
Generally be used to carry the industrial pump of Korrosionsmedium, adopt common corrosion resisting centrifugal pump.General corrosion resisting centrifugal pump is made of pump case, impeller, bonnet, sealing, pump shaft, support, base plate etc., before each start, must draw liquid, makes and fills water in the pump case, the operation of could starting shooting.In order to reach the purpose of self-priming, once the someone manufactured experimently a kind of self-priming pump, promptly improved the suction pipe of pump; add the bead of a diameter at the suction mouth of pipe, constitute a simple automatic ball valve, after the shutdown greater than suction port; bead is blocked suction port, does not allow aqueous reflux in the pump case.But because the no pressure support of bead sealing, the time one is long, and the liquid in the pump case is all missed, and still need draw the liquid start.
The purpose of this utility model is exactly the deficiency at existing centrifugal pump, provides a kind of self-priming reliable corrosion resistant lining self-priming pump.
The purpose of this utility model is achieved in that the lining self-priming pump is made of pump case, impeller, bonnet, sealing, pump shaft, support, base plate etc., it is characterized in that being provided with in the self-priming pump spiral case 2 and liquid storage cylinder 9, the radial wall of the volute runner of spiral case 2 is the helicoid that double end has gradient, spiral case 2 is located in the pump case 1, constitute liquid storage cylinder 9 between spiral case and the pump case, spiral case is provided with pipeline 11, liquid storage cylinder 9 and the 10(of blade wheel chamber spiral case inner chamber) communicate; The intake pipe center line of lining self-priming pump is higher than the pump shaft center line; Pump shaft 6 adopts with impeller 3 and is threaded; Spiral case 2 is made with fluoroplastic or Fluoroine-containing plastic alloy, and the contacted overcurrent of all of pump and medium position is lined with one deck fluoroplastic or Fluoroine-containing plastic alloy.For the ease of the field-strip of pump, the outage 12 that pump case 1 is provided with closure communicates with liquid storage cylinder 9.When the lining self-priming pump started to work, the rotation of impeller was at first discharged blade wheel chamber 10 with liquid storage cylinder 9 interior liquid, make to form negative pressure in the spiral case, the air in the intake pipe is filled up spiral case, liquid storage cylinder, and liquid is inhaled into intake pipe under the effect of negative pressure, enter blade wheel chamber, reach the purpose of self-priming operation.
The utility model is rational in infrastructure, technology is simple, and cost is low, and self-priming performance is good, need not draw the liquid pump priming before the start, and is easy to use, reduces labor intensity, increases work efficiency.Cross flow medium and directly do not contact, strengthened the antiseptic property of pump, prolong the working life of pump with metalwork.
Accompanying drawing is a structural representation of the present utility model, 1 pump case, 2 spiral cases, 3 impellers, 4 bonnets, 5 sealings, 6 pump shafts, 7 supports, 8 base plates, 9 liquid storage cylinders, 10 blade wheel chamber, 11 pipelines, 12 outages, 13 intake pipes, 14 outlet pipes among the figure.
Narrate a case study on implementation of the present utility model below in conjunction with accompanying drawing.
Support 7 is fixed on the base plate 8, and on support 7, impeller 3 adopts dextrorotation to be connected to the screw thread installation with pump shaft 6 to pump shaft 6 by Bearing Installation, and pump case 1, spiral case 2 install and fix together with bonnet 4 respectively, and spiral case 2 is in pump case 1.Constitute liquid storage cylinder 9 between spiral case 2 and the pump case 1, spiral case is provided with the spiral case inner chamber that pipeline 11 constitutes liquid storage cylinder 9 and the 10(of blade wheel chamber spiral case 2 and bonnet 4) be communicated with.Establish the outage 12 of with closure on the pump case 1.The center line of intake pipe 13 is higher than the center line of pump shaft 6.Spiral case adopts fluoroplastic or Fluoroine-containing plastic alloy to be processed into.Overcurrent positions such as the contacted bonnet 4 of all of pump and medium, impeller 3, pump case 1, intake pipe 13, outlet pipe 14 lining system one deck fluoroplastic or Fluoroine-containing plastic alloy.
Claims (2)
1, a kind of lining self-priming pump that constitutes by pump case, impeller, bonnet, sealing, pump shaft, support, base plate etc., it is characterized in that self-priming pump is provided with spiral case (2), liquid storage cylinder (9), the radial wall of the volute runner of spiral case 2 is the helicoid that double end has gradient, spiral shell shell (2) is located in the pump case (1), liquid storage cylinder (9) is arranged between spiral case and the pump case, impeller (3) is installed with screw thread and is connected on the pump shaft (6), all of pump are lined with one deck fluoroplastic or Fluoroine-containing plastic alloy with crossing the contacted position of flow medium, and spiral case (2) is made with fluoroplastic or Fluoroine-containing plastic alloy.
2, self-priming pump according to claim 1 is characterized in that said pump case (1) is provided with the outage (12) of with closure.
