Description
Technical field
The utility model is related to a kind of modified hydraulic turbine, water pump blade angle hydraulic isochronous controllers, belong to hydraulic turbine tune
Speed variator technical field.
Background technology
Chinese invention patent CN101344064B discloses a kind of hydraulic turbine, water pump blade angle isochronism cspeed governor, it is logical
It crosses using interior fuel feeding hydraulic regulation, makes regulating system good seal performance, do not leak, hydraulic device body uses overhead, adjusts
Saving force regulating device body and unit synchronous rotary, unit operation at the rotor main shaft upper end of main motor, work will not send out
Raw lift axis phenomenon, unit operation are stablized, and in unit operation, axial displacement accident, blade angle will not occur for regulation blade angle
Degree adjusting is sensitive, improves the safety and reliability of the hydraulic turbine or pump equipment, reduces use cost, use and maintenance side
Just, although the patent of invention is from the vibration for largely solving the existing hydraulic turbine, water pump assembly is big and hydraulic fluid leak
Problem, but adjust body and connected everywhere using flanged joint, sealing ring is provided between flange, under normal circumstances can
Ensure sealing against leakage, but, due to water pump blade angle adjuster relevant apparatus：Adjustment axis and connecting lever and pulling plate, leaf
Under water, working environment is severe, and the time, which has been grown, inevitably gets rusty for the another part work such as piece shaft, when underwater angle modulation machinery rust is dead,
Required adjusting force can increase considerably, and several times of normal regulating power are likely to be breached when serious！The adjusting force increased can make adjusting
Mechanism overload operation, during the serious overload operation of adjuster two flange connections can bear than it is normal when more than several times of pulling force, at this
Under kind of operating mode, two flange of junction can deform larger, after flange is deformed by overload pulling force, cause the seal washer between two flanges
Loosening makes sealing performance be deteriorated, and since sealing performance is deteriorated and under extra-high oil pressure, hydraulic fluid leak, hydraulic oil can inevitably occur
When leaking larger, regulating system can not just work normally.
The content of the invention
The purpose of this utility model is that in view of the above shortcomings of the prior art, one kind is provided and can effectively prevent adjuster

Spend transmitter connection；Equipped with hydraulic station, check valve and reversal valve in fuel reserve tank, pass through high-pressure oil pipe between hydraulic station and reversal valve
It connects, piston is provided in oil cylinder, oil cylinder is divided into upper cylinder and lower oil cylinder, upper high-pressure oil pipe and lower high-pressure oil pipe difference by piston
It is connected with upper cylinder and lower oil cylinder；It is characterized in that：Be tightly connected between pedestal and oil cylinder by snap ring and partition plate B, oil cylinder and
It is tightly connected between fuel reserve tank by snap ring and partition plate A；Piston lower portion is provided with piston rod, piston rod through pedestal and oil cylinder it
Between partition plate B, O shape seal washers are provided between piston rod and partition plate B, the bottom of piston rod is connected with adjusting by shaft coupling
Bar.
The snap ring is in circular ring shape, and snap ring is cut into eccentric circular ring A, eccentric circular ring B, eccentric circular ring C and eccentric circular ring D.
The eccentric circular ring D is dovetail-shape, and eccentric circular ring A, eccentric circular ring B, eccentric circular ring C are bigger than eccentric circular ring D.
For the partition plate A and partition plate B in patty, partition plate A is provided centrally with the through hole passed through for safety valve, partition plate B
It is provided centrally with the through hole passed through for piston rod.
The snap ring internal diameter is less than the diameter of partition plate A and partition plate B, and the outer diameter of snap ring is more than the diameter of partition plate A and partition plate B,
The diameter of partition plate A and partition plate B are more than the internal diameter of oil cylinder.
The snap ring and partition plate A, partition plate B coaxially stack setting respectively, and snap ring is provided with above partition plate A, partition plate B's
Lower section is provided with snap ring.
The advantageous effect of the utility model compared with prior art is：
The sealing that the modified hydraulic turbine, water pump blade angle hydraulic isochronous controller are cooperated using snap ring and partition plate
Structure can make governor body form an overall structure, even if under the conditions of bad working environments, cause to connect because pulling force is excessive
The flange distortion at place, and snap ring and partition plate leak like that without phase seal washer, because either upper cylinder is in height
Laminated oil zone still play oil cylinder be in high pressure oil area, partition plate A and partition plate B due to diameter itself be more than oil cylinder internal diameter so that partition plate A without
Method is moved down along oil cylinder, partition plate B can not be moved up along oil cylinder, and snap ring has been stuck in the top of partition plate A and the lower section of partition plate B,
So that partition plate A and partition plate B can not just be moved up and down at all, even if it is tight that leakage will not be generated due to pulling force is big under severe conditions
Weight to oil pressure deficiency prevents to be entire regulating system from working.
