Abstract
The utility model is a new rotating jet pump which is a high voltage chemical pump with character of high efficiency. The pump is internally provided with a rotating cavity blade wheel, a static current collecting pipe and a pump sucker which is communicated with the rotating cavity. The blade of impeller takes a longitudinal direction even rectangle cross section interval channel, which has a simple structure and can be gained by machine processing, thereby avoiding the shortcoming that the past reduce section interval channel is provided with a casting, and ensuring the processing precision and roughness. The liquid outlet is opened largely, which effectively increases the lift of the pump. The cross section of the current collecting pipe takes a streamline shape, which is convenient for polishing. The turbulent flow loss of liquid to the current collecting pipe is small. The pump has the advantages of smooth Q-H curve, high efficiency, simple and reliable structure, easy seal and serialization.
Description
A kind of novel rotary jet pump is the novel chemical pump of a kind of advantages of simplicity and high efficiency high pressure, belongs to non-varactor pump (F04D).
Existing rotary-jet impeller blade is the diametral curve variable section runner, can only adopt casting method to obtain, and its finished product accuracy and roughness are low, and liquid divergence loss in impeller is big, and the loss of header pipe flow-disturbing is big in addition.
The purpose of this utility model is to propose a kind of novel rotary jet pump, addresses the aforementioned drawbacks, and realizes that loss is little, and the efficient height is easily made processing, safeguards etc.
A kind of novel rotary jet pump is provided with the rotation pelvic cavity 5 and the impeller 7 that are connected with pump shaft 3 in pump case 4, establish static having suction port (6.1) and lead to the header pipe (6) that pump shows mouthful (6.2) in the rotation pelvic cavity; Establish Pump Suction Nozzle (11) at pump one end, and be communicated with header pipe suction port space of living in (6.3), it is characterized in that impeller blade is rectangular cross section runner (7.1) radially through passage (10).Angle α is big for impeller blade runner liquid outlet, and 80 °～90 ° of general α selections are preferable.Header pipe (6) section is a streamline-shaped 6.4.
Description of drawings
Fig. 1 the utility model structural drawing
Fig. 2 impeller 7 diagrammatic sketch
Fig. 3 runner section 7.1 diagrammatic sketch
Fig. 4 header pipe 6 section diagrammatic sketch, (dotted line is the header pipe section configuration of prior art among the figure)
Embodiment:
See Fig. 1, rotation pelvic cavity 5 is connected with exterior motor through pump shaft 3 with impeller 7 in pump case (4).Static header pipe 6 has suction port 6.1, and leads to pump discharge 6.2.Pump one end is established Pump Suction Nozzle 11, is communicated with through path 10 and header pipe suction port space 6.3 of living in.Item 1 is the bearing of pump shaft 3, and item 2 is a bearing housing, and item 8 is sealing.Item 9 is a suction casing.See that Fig. 2, Fig. 3 impeller 7 blades are rectangular cross section runner 7.1.Blade outlet angle is at 80 °～90 °.See Fig. 4, the header pipe section is a streamline-shaped 6.4.Working procedure: motor drives pump shaft 3, rotation pelvic cavity 5 impellers 7 rotate, and centrifugal force produces vacuum, and liquid enters impeller through suction port 11 and obtains energy and enter in the rotation pelvic cavity space 6.3 high speed rotating thereupon; Static header pipe sucks the kinetic energy fluid by suction port 6.1, and converting kinetic energy to pressure can be by pump discharge 6.2 output.
The utility model beneficial effect:
1. blade is the rectangular section runner simple shape, radially linearly, can adopt the forging machine Processing obtains, and prevents the defective that adopts foundry goods over, can guarantee Impeller Machining precision and coarse The degree requirement. 2. angle of outlet α is big, the Effective Raise pump lift. 3. the header section is stream Line style 6.4 compares thickness with prior art header section configuration (shown in Fig. 4 dotted line) S ' drops to this streamlined being convenient to of S and polishes, and liquid is little to the flow-disturbing loss of header. 4. New pump has more stably Q-H curve, and the efficient height is simple and reliable for structure, is convenient to close Envelope is convenient to seriation.
Claims (3)
1, a kind of novel rotary jet pump is provided with the rotation pelvic cavity (5) and the impeller (7) that connect with pump shaft (3) in pump case (4), establish the static header pipe (6) that has suction port (6.1) and lead to pump discharge (6.2) in the rotation pelvic cavity; Establish Pump Suction Nozzle (11) at pump one end, and be communicated with header pipe suction port space of living in (6.3), it is characterized in that impeller blade is rectangular cross section runner (7.1) radially through passage (10).
