Description
Technical field
The present invention relates to a kind of axial flow pump blade inner angle adjustment devices.The invention further relates to one kind to have above-mentioned axial-flow pump leaf
The axial-flow pump of piece angle adjustment device.
Background technique
Large Axial Flow Pump is a kind of universal machine, and the big lift of its flow is low, and application is extremely extensive, and agriculture large area is irrigated and row
Thermo-power station recirculated water and dock lifting water level that flood, municipal drainage, conveying need cooling water inflow very big etc..
The characteristics of axial-flow pump and advantage are that flow is big, structure is simple, light-weight, outer dimension is small.The body of axial-flow pump is
Tubulose, therefore occupied area is small.
Axial-flow pump can be divided into vertical, inclined and three kinds horizontal according to pump shaft installation site.Only pump housing form is not between them
Together, internal structure is essentially identical.It is vertical-type axial-flow pump that China, which produces more,.Impeller is fully immersed in when vertical axial-flow pump work
In water, when starting, need not fill pump, simple to operate.
For adjustable type axial-flow pump, when operation conditions change, as long as changing blade angle, i.e. adjustable vane.It adjusts
Formula axial-flow pump is divided into half adjustable type and full adjustable type two types.The blade of half adjustable type be it is removable, change angle need handle
Blade release is adjusted by hand.Full adjustable type is the angle for changing blade automatically by a set of special follower, large-scale
The blade of axial-flow pump is mostly full adjustable type, can realize that blade is adjusted entirely when not shutting down.
Traditional axial flow pump blade inner angle adjustment device passes through the driving of the upper and lower two grease chambers pressure difference of oil cylinder 31 as shown in Figure 1:
Piston 30, piston 30 connect piston rod 33 drive crosshead 32 vertically, lower movement.Further, by along Fig. 1 A-A cut open
The sectional view 1A opened is clearly visible, and crosshead 32 is fixed with earrings 36,34 connecting lug 36 of connecting rod and connecting lever 35,35 band of connecting lever
Movable vane piece 37, so that the axial movement of piston 30 to be become to the angulation change of blade 37.
There is following aspects in this technical solution: firstly, being driven by the crosshead 32 of lower part by connecting rod 34
Blade adjusts the strength that blade needs and directly passes oil cylinder 31 back by single connecting rod driving, causes pressure in oil cylinder 31 higher, thus
Oil pump station and petroleum pipeline system also have elevated pressures.Secondly, the error generated during link transmission eventually results in blade 37
Angular adjustment error, to influence hydraulic efficiency and radial force.In addition, since connecting lever 35 and 34 connection space of connecting rod are short, because
And 37 angle of blade can not be adjusted precisely, be easy to cause the stuck of connecting rod 34 and connecting lever 35, caused adjustment structure that can not work.
Accordingly, it would be desirable to propose a kind of more reasonable axial flow pump blade inner angle adjustment device, adjustment process can be prevented
In it is stuck, realize that angle is precisely controlled, and reduce the pressure in oil supply system, it is so as to realize more smooth smooth
Axial flow pump blade inner angular adjustment.
Summary of the invention
In order to solve the above technical problems, solving large size the invention proposes a kind of axial flow pump blade inner angle adjustment device
Axial flow pump blade inner angular adjustment precision is not high, and blade is high, at high cost with the stuck problem of connecting rod and hydraulic oil unit charge oil pressure
