Abstract

The invention discloses a drum-type displacement pump, comprising a main shaft for connecting with a motor, wherein the upper part of the main shaft is slantwise provided with a drum which swings along with the rotation of the main shaft; the periphery of the drum is evenly distributed with more than three volume cavities which form a cylinder body; the outer side of the drum is evenly provided with ball bearings; and the lower part of the ball bearing is connected with one end of a connecting rod, and the other end of the connecting rod is spherical and is connected with a piston arranged in the volume cavity in a flexible manner. The displacement pump can satisfy the high-lift requirement on electric diving pumps in desert or plateau areas, and the structure has less friction pairs, thus enabling the working efficiency to be higher compared with the existing displacement pump, and being very suitable for unwatered areas like desert and plateau, and the advantage is especially obvious when the displacement pump is applied into the fields such as drinking water extracting, desert plant trickle irrigation and the like in remote peasant households and villages and small towns under the condition of electricity scarcity compared with the electric diving pumps driven by taking solar energy as powder.

Description

A kind of drum-type displacement pump

Technical field

The present invention relates to a kind of pump, particularly a kind of displacement pump that is applied in the Submerged Motor Pumps industry.

Background technique

Submerged Motor Pumps in the market generally adopts centrifugal pump as the pump housing, because centrifugal pump delivery is big, when the lift requirement is lower, can bring into play very high working efficiency, so centrifugal pump has obtained on Submerged Motor Pumps using widely.But in the place of lacks of water such as desert or plateau, level of ground water is lower, and the lift that requires in the time of Submerged Motor Pumps work is but than higher, and existing centrifugal pump is difficult to satisfy the requirement of using, and must adopt displacement pump.Yet existing displacement pump ubiquity causes the low problem of working efficiency owing to friction pair is more, and this problem is all the more obvious under as the situation of driven by energy Submerged Motor Pumps work with solar electrical energy generation in desert or plateau section.

Summary of the invention

The technical problem that the present invention will solve provides a kind of displacement pump, can satisfy desert or the plateau section demand high-lift to Submerged Motor Pumps, and when high-lift, have high efficiency, helps saving the energy.

In order to solve the problems of the technologies described above; A kind of drum-type displacement pump of the present invention comprises being used for the main shaft that is connected with motor, and the top of said main shaft has to be tiltedly installed with main shaft rotates the rotating cylinder of swinging; Evenly be furnished with the cavity volume more than three around the rotating cylinder and form cylinder body by said cavity volume; The outside of rotating cylinder evenly is equipped with ball bearing, and the bottom of said ball bearing is connected with an end of connecting rod, and the other end of connecting rod is spherical and flexibly connects with the piston that is arranged in the cavity volume; The top of said main shaft is connected with down inclined shaft; Following inclined shaft is connected with inclined shaft through the screw rod that tilts, and is separately installed with the bearing pack of being made up of at least one bearing on the said upper and lower inclined shaft, and said rotating cylinder is sleeved on the outside of this bearing pack.

As the further improvement of technique scheme, the arranged outside of said rotating cylinder has more than one position-limited shaft, and roller is installed on the position-limited shaft, and a side of this roller is fixed with and limits the baffle plate that it rotates around main shaft.

The invention has the beneficial effects as follows: owing to adopted said structure; This displacement pump converts the rotation of the main shaft swing through rotating cylinder to cavity volume inner carrier move up and down; Can satisfy desert or the plateau section demand high-lift to Submerged Motor Pumps; And the friction pair of this structure is less; Make working efficiency higher, be fit to very much be applied in water-deficient areas such as desert, plateau than existing displacement pump, particularly under the situation of short of electricity with solar electrical energy generation as the Submerged Motor Pumps of driven by energy be applied to remote peasant household, the villages and small towns potable water extracts and fields such as desert plant drip irrigation in advantage more obvious.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the present invention is done further detailed explanation.

Fig. 1 is an internal structure schematic representation of the present invention;

Fig. 2 is the internal structure schematic representation of rotating cylinder.

Embodiment

With reference to Fig. 1; A kind of drum-type displacement pump of the present invention comprises being used for the main shaft 1 that is connected with motor, and the top of said main shaft 1 has to be tiltedly installed with main shaft 1 rotates the rotating cylinder of swinging 2; Evenly be furnished with the cavity volume 3 more than three around the rotating cylinder 2 and form cylinder body by said cavity volume 3; The outside of rotating cylinder 2 evenly is equipped with ball bearing 4, and the bottom of said ball bearing 4 is connected with an end of connecting rod 5, and the other end of connecting rod 5 is spherical and flexibly connects with the pistons 6 that are arranged in the cavity volume 3.Owing to adopted said structure; This displacement pump converts the rotation of main shaft 1 swing through rotating cylinder 2 to cavity volume 3 inner carriers 6 move up and down; Can satisfy desert or the plateau section demand high-lift to Submerged Motor Pumps; And the friction pair of this structure is less; Make working efficiency higher, be fit to very much be applied in water-deficient areas such as desert, plateau than existing displacement pump, particularly under the situation of short of electricity with solar electrical energy generation as the Submerged Motor Pumps of driven by energy be applied to remote peasant household, the villages and small towns potable water extracts and fields such as desert plant drip irrigation in advantage more obvious.

With reference to Fig. 2; The top of said main shaft 1 is connected with down inclined shaft 7; Following inclined shaft 7 is connected with inclined shaft 9 through the screw rod 14 that tilts, and is separately installed with the bearing pack of being made up of at least one bearing 8 on the said upper and lower inclined shaft 9,7, and said rotating cylinder 2 is sleeved on the outside of this bearing pack 8.The outside of said rotating cylinder 2 evenly is provided with more than one position-limited shaft 21, and roller 11 is installed on the position-limited shaft 21, and a side of this roller 11 is fixed with and limits it around the baffle plate 12 that main shaft 1 rotates, and sees Fig. 1.Said main shaft 1 is fixedly connected through mounting flange 16 with following inclined shaft 7, and said screw rod 14 connects upper and lower inclined shaft 9,7 fixing through side keyway.During displacement pump work, motor driving main shaft 1, main shaft 1 drives inclined shaft 7 rotations down through mounting flange 16; Rotating cylinder 2 continuous its true dip directions of conversion evenly are provided with roller 11 owing to be sleeved on the outside of the rotating cylinder 2 on the bearing pack 8, and roller 11 receives baffle plate 12 to be stopped; Can not follow upper and lower inclined shaft rotates; And only can swing, therefore can drive cavity volume 3 inner carriers 6 to move up and down through connecting rod 5, carry out liquid and carry.In addition, for the pair of reducing friction, increase work efficiency, by upper and lower bearing 10,13 location, said roller 11 is installed in position-limited shaft 21 outsides through the bearing on the position-limited shaft 15 to said upper and lower inclined shaft 9,7 respectively.
