Description
Technical field
The utility model belongs to machinery field, is related to the adjustment of blade angle such as water pump device more particularly to a kind of modified
Full angle blade control device.
Background technique
Efficiency, stability of operation of water pump etc. change with flow, lift, and flow and lift are with season, rainfall
Often change Deng different, this just needs the angle of water pump blade adjustable, is changed with adapting to the variation of duty parameter, makes
Water pump operation is optimal state, especially there is the pumping plant of drinking-water and demand of draining flooded fields, and needs to pump the performance for having way traffic, i.e.,
It rotates and reverse all and has preferable water outlet efficiency and stability, and current two-way pump station, the method for use is for blade
Bidirectional blade model is selected in selection, but efficiency is relatively low, and cavitation performance is not good enough, and vibration and noise are all big.Assuming that not using two-way
Model greatly improve blade rotation 180 degree or so inverted running, such efficiency and stability will.
But existing water pump vane adjusting device is divided into mechanical adjustment and hydraulic regulation, and mechanical adjustment uses motor as dynamic
Power, hydraulic regulation use oil pressure as power, and power used by two kinds of regulative modes is different, but all by driving adjustment axis above and below
(horizontal pump is front and back) movement, pulls adjustment disk that connecting rod is driven to rotate blade, both modes are maximum the disadvantage is that adjusting leaf
The angular range very little of piece, which, which determines, cannot achieve blade big angle rotary, with less meeting two-way pump about 180 degree
Wide-angle adjust requirement.
Utility model content
The utility model is in view of the above shortcomings of the prior art: existing water pump vane adjusting device adjusts the angle of blade
Range very little is spent, cannot achieve blade big angle rotary, and a kind of a kind of modified full-shape of energy wide-angle adjusting blade is provided
Spend blade control device.
In order to solve the above technical problems, the technical solution adopted in the utility model is:
A kind of modified full angle blade control device, including transmission shaft, hub unit and at least 2 blades, transmission shaft

Operation.
Comparative example
It enumerates some pumping plant and needs forward and reverse operation (same pumping plant realizes diversion and water drainage function)
* pumping plant 3200ZGQ30 silo infusion pump menu (revolves blade using modified full angle regulating device to model
Turn about 180 degree to run)
Performance parameter table
* pumping plant 3200ZGSB30 silo infusion pump selects double-direction model hue angle (ipsilateral can only be finely tuned with former regulating device)
Performance parameter table
To meet pumping station operation requirement, we have selected unidirectional model respectively, adjust about 180 degree operation (running in turn),
With use double-direction model, the method for angle adjustment is run, and the unidirectional mature alternative comparison of model is more, and double-direction model compared with
It is few, because unidirectional model can be advanced optimized for the pumping plant parameter request, relatively it is easy, and double-direction model is difficult to have
Big optimization is promoted, because double-direction model needs to take into account inverted running requirement, model performance can not have bigger raising.It is exactly
It being compared from existing two kinds of models, unidirectional model is averagely higher by about 15% than double-direction model efficiency, and peak efficiency difference is about high by 26%,
Overall power of motor is higher by about 11%, moreover unidirectional model can also advanced optimize.In general, high-efficient, the low fortune of specific efficiency
Row is more stable, can affirm, the use of the modified full angle blade control device of the utility model, for the tune of blade angle
Section, will be basic change, suitable for numerous occasions for needing blade adjustments, especially for the pump for needing to realize way traffic
It stands, provides a kind of completely new settling mode.
