Description

The conical screw pump
Technical field
The utility model relates to the mechanical pump technical field, refers to especially a kind of conical screw pump.
Background technique
The conical screw pump that exists in the market mostly is the described conical single-screw pump according to ZL88211709.2, screw rod, the pump housing form the not parallel rotation centerline of bus, the enveloping outer enclosure curve just can change both radial clearances or interference by the axial position of adjusting screw rod and pump block during use not on a cylindrical body.But depend the degree of vacuum that produces in the screw rod working procedure in the conical screw pump alone, be not easy the medium in the preposition cavity volume is sucked fully, namely prior art exists delivery pressure low, and flow is little, ineffective problem and defective.Therefore, improve the ability of the propulsive medium of conical screw pump, the working efficiency that namely improves the conical screw pump just seems particularly important.
The applicant is in view of disappearance and the inconvenience of above-mentioned known conical screw pump, and the spirit of adhering to research and innovation, keeping on improving is utilized its professional eye and professional knowledge, works out a kind of Novel tapered screw pump.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of raising delivery pressure and flow are provided, and improves the conical screw pump of working efficiency.
The utility model is achieved through the following technical solutions, and comprises that the shaping bus is the pump housing and the helical blade of taper, is evenly equipped with a plurality of guide plates on the described helical blade, and the blade face rigidity of the bottom surface of guide plate and helical blade is joined; Described helical blade front end also is provided with a turbine, and turbine and helical blade all are fixed on the pump shaft.The turbine Main Function is supercharging, improves flow, thereby improves power and the pressure of conical screw pump.
The spiral angle of climb that respectively saves of described helical blade equates.
Described guide plate is crescent shape but is not limited to crescent shape, also can be the shapes such as rectangular, triangle, arc.
The working principle of turbine device and guide plate is:
Turbine device is exactly a kind of compressor in fact, increases the flow of conical screw pump by compressed media, and in general, turbine utilizes the medium that coaxial turbine blade force feed is sent here by turbine chamber in the turbine chamber, makes it supercharging and enters pump housing inner chamber.When the conical screw revolution speed speeds, secondary speed also speeds synchronously, and turbine blade just compresses more medium and enters pump housing inner chamber, and the pressure of medium and flow increase the output power that can increase the conical screw pump.Turbine device mainly is comprised of turbine chamber and turbine blade, at first is that the media port that advances of turbine chamber links to each other with media cavity before the conical screw pump, and row's media port then links to each other in pump housing inner chamber; Turbine blade evenly distributes and is contained in the turbine chamber both coaxial gun iron links.
The Main Function of guide plate is water conservancy diversion, thereby accelerates the flow of medium; Increase vane stress intensity.The guide plate uniform distribution device is on each joint helical blade.The crescent shape blade bottom surface of guide plate blade face rigidity complete and each joint helical blade is joined, medium contact in the media cavity between the front and rear wall of guide plate and each the joint helical blade, and can not the sealing medium chamber.Described meniscate guide plate produces resistance by the two sides, front and back and pushes medium in the media cavity in media cavity, make it to be pushed in the interior rear media cavity of base.When the rotating speed of conical screw pump speeds, helical blade and crescent shape blade rotary speed also speed synchronously, and the crescent shape blade pushes faster medium and enters rear media cavity.So just can accelerate the flow of conical screw pump.
The utility model has the advantage of, utilize turbosupercharging and guide plate water conservancy diversion, improved delivery pressure and the flow of conical screw pump, improved working efficiency.In industry, agricultural, water conservancy, chemical industry, the food and medicine processing industry future that all is widely used.

Embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present utility model is described further, shown in Fig. 1 to 3a, 3b, the utility model comprises that the shaping bus is the pump housing 7 and the helical blade 4 of taper, be evenly equipped with a plurality of guide plates 12 on the described helical blade 4, the blade face rigidity of the bottom surface of guide plate 12 and helical blade 4 is joined;
Described helical blade 4 front ends also are provided with a turbine 3, and turbine 3 all is fixed on the pump shaft 9 with helical blade 4.Turbine 3 Main Functions are superchargings, improve flow, thereby improve power and the pressure of conical screw pump.
The spiral angle of climb that respectively saves of described helical blade 4 equates.
Described guide plate 12 is crescent shape but is not limited to crescent shape, also can be the shapes such as rectangular, triangle, arc.
During specific operation, suppose that the medium in the conical screw pump is assumed to be oil, described medium is by the filler opening 1 on the front cover 8, enter in the oil sucting cavity 2 that communicates with each other, drive pump shaft 9, turbine 3, helical blade 4 rotations by belt pulley 10, oil is sucked the turbine 3 from oil sucting cavity 2, enter the pump housing 7 by turbine 3, carry by helical blade 4, and by equally distributed guide plate 12 water conservancy diversion on the helical blade 4, finally enter into going out in the oil pocket 5 of rear base 11, by going out oil pocket 5 oil is sent to oil outlet 6.
The described pump housing 7 shaping buses show taper, and are corresponding with helical blade 4; The pump housing 7 is connected with front cover 8, rear base 11 and communicates, and forms a conical cavity in the middle of the pump housing 7, and turbine 3 and helical blade 4 are arranged in this cavity; Pump shaft 9 runs through the axis of front cover 8, the pump housing 7, turbine 3, helical blade 4, rear base 11.The spiral angle of climb of described helical blade 4 equates, should form each other an equidistant cavity by this each joint helical blade, oil produces pressure owing to be subject to the taper pump housing 7 inwalls extruding compression in this cavity, finally by equally distributed guide plate 12 is with the oil in the cavity between each joint helical blade 4 on each joint helical blade 4, water conservancy diversion transfers to going out in the oil pocket 5 in the rear base 11.
The pump housing of the present utility model, the aobvious taper of screw rod shaping bus utilize turbosupercharging and guide plate water conservancy diversion.This programme can enlarge conical screw pump work field, and delivery pressure is high, and flow is large, increases work efficiency.In industry, agricultural, water conservancy, chemical industry, the food and medicine processing industry future that is widely used.
The above embodiment has only expressed a kind of mode of execution of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model claim.Should be pointed out that for the person of ordinary skill of the art without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
