Abstract
The invention discloses a guide vane angle regulating device for submersible pumps, which is convenient to regulate the guide vane angle. The guide vane angle regulating device comprises a crank, a driven ring, a driving ring and a drive plate, wherein the driven ring and the driving ring are bonded and connected, one end of the crank is connected with the driven ring in a rotating mode, the other end of the crank is used for connecting and regulating the guide vane angle, a connecting mechanism for connecting the driving ring and the drive plate is arranged between the driving ring and the drive plate, and the drive plate is connected with a drive link. The guide vane angle regulating device can be used for regulating underground or underwater guide vane angle by ground operation. In the invention, by means of the triangular drive plate and a connecting link device, the guide vane can be freely driven to rotate clockwise or anticlockwise. Meanwhile, the application of the crank ensures that the guide vane angle can be greatly changed only when the driving ring and the driven ring rotate by small distance.
Description
Technical field
The present invention relates to a kind of submersible pump stator angle regulator, relate in particular to a kind of submersible type axial-flow pump, mixed flow pump stator angle regulator.
Background technique
Submersible type axle, mixed flow pump have been brought into play positive benefit in the national product construction since introducing China the sixties, control flood and drain flooded fields, field such as irrigation, industrial and mineral, municipal administration, agriculture plumbing and sewage treatment brought into play positive effect.Since electromechanical, compact structure, volume is little, and is easy for installation, and application constantly enlarges, and has progressively replaced old-fashioned axial flow machine, and power also improves constantly, and the Submerged Motor Pumps of China's peak output reaches more than the 1000KW at present.Current, China is carrying forward vigorously energy-saving and emission-reduction work, promote energy-saving efficient motor, simultaneously, submersible type axle, mixed flow pump power constantly enlarge, and the requirement of efficient is more and more higher, have good stable and reliability again, therefore, necessarily require submersible type axle, mixed flow pump can be in bigger operating mode scope efficient operation.Yet the stator of submersible type axle, mixed flow pump and blade are difficult to realize the efficient operation of big operating mode scope, and are easy to generate cavitation after a tilt fixing installation, phenomenons such as vibration and noise, thus accelerate mechanical damage.
Summary of the invention
The invention provides a kind of submersible pump stator angle regulator that makes things convenient for the stator angular adjustment, the present invention can realize underground or the adjustment of stator angle under water by terrestrial operation, thereby realizes the efficient operation of big operating mode scope.
The present invention adopts following technological scheme:
A kind of submersible pump stator angle regulator, comprise: crank, driven torus, active ring and driver plate, driven torus with initiatively between the ring bonding be connected, one end and the driven torus of described crank are rotationally connected, the other end of crank is used to connect and adjust the angle of stator, between ring initiatively and driver plate, be provided with and be used to be connected the initiatively bindiny mechanism of ring and driver plate, be connected with drive link at driver plate.
In the civil engineering stage, carry out the seat ring of submersible type axle, mixed flow pump, the initiatively installation of ring, driver plate and adjusting handle etc. in advance, treat that civil engineering finishes, submersible type axle, mixed flow pump are slided along guide rail, realization is installed from lotus root, and rotation hand wheel is realized the bidirectional modulation of exit guide blade.Major advantage is as follows:
1. owing to diving axle, mixed flow pump motor are dived under water, motor must seal fully, and this special structure makes that the adjusting of exit guide blade is very difficult.The present invention does not influence the main structure of diving axle, mixed flow pump, has well protected motor seal.
2. this stator controlling device has realized the bidirectional modulation to stator, by a triangle driver plate and connecting rod means, be free to make stator clockwise or be rotated counterclockwise, the application of this crank makes that initiatively ring and driven torus only need rotate very little distance and just can realize the conversion that the stator angle is bigger among the figure simultaneously.
3. the present invention is that automatically coupling is installed, and need not manually, along guide rail Submerged Motor Pumps is slipped into pit shaft, and Submerged Motor Pumps can lean on inclined-plane centering to fit on the seat ring automatically, uses O type rubber seal simultaneously, from motive sealing, can not produce problem such as leak.When water pump normally overhauled, directly water pump being sling got final product, and need not load and unload the stator controlling device, therefore, can not make the complexity of safeguarding change because of having increased the exit guide blade controlling device.This automatic coupled structure has been saved and installed and engineering time, does not need manually to enter the shaft bottom, and is extremely convenient and swift.
4, the present invention is provided with the inclined-plane in the upper end of active ring key groove, lower end at driven torus also is provided with the inclined-plane, that is: the rectangular of protruding key and keyway notch section and the trapezoidal shape that is formed by stacking, making when Submerged Motor Pumps is installed automatically can automatic centering and slip in the keyway, can not cause the driven torus of water pump can't just embed in the active ring because of the little deviation of civil engineering, make to cooperate closely reliably, easy for installation.
What 5, movable guide vane of the present invention used is self-align ball bearing, the movement locus of crank when rotating with driven torus is not always on the circle at driven torus, therefore, if use plain bearing, can be stuck automatically because interfere, can't rotate the use of self-align ball bearing, when having solved driven torus cleverly and having driven the crank rotation, the problem that crank and driven torus movement locus do not overlap.
