Abstract
The utility model discloses an external servomotor for water pump and turbine impeller, wherein, an servomotor 4 is shifted from the inside of a runner body to the outer end of a generator; the servomotor is connected with an oil-supply head through a shock eliminating connector 10; a servomotor main shaft 5 is fixed with a transmission shaft 3 which is connected with an impeller of the runner; an oil inlet cavity a and an oil inlet cavity b, two inner hole grooves of an oil-supply head piston 2, a hose 8 and a hose 9 as well as two oil circuits inside the servomotor main shaft are respectively communicated with a working oil cavity A and a working oil cavity B to form oil circuits; a servomotor piston 7 is fixed on a main shaft 5 of the servomotor; an oil sump tank 6 is fixed outside the cylinder body of the servomotor 4, thus the oil pollution of equipment to lower reaches is avoided, the equipment is convenient to be maintained, and medium and small units can also use rotating propeller type.
Description
Technical field
The utility model relates to the control gear of a kind of water pump, water turbine blade.
Background technique
In technique known, change oar axial flow, tubular, and diagonal flow type water pump, rotary wheel of water turbine blade servomotor be distributed on the rotor body inside of water pump, water turbine, the pressure oil of operation blade servomotor must be by in two working oil chambers of A, B that just can enter the blade servomotor behind the inside and outside oil pipe of lubricant receiver, make the left and right or upper and lower move operation runner of its piston blade unlatching or close.The shortcoming that this known device exists is: lubricant receiver and the leakage of oil of runner blade root are serious, so that cause the serious oil pollution in river, downstream; Runner internal structure bulky complexization is keeped in repair very difficultly, has also reduced the conveyance capacity of runner; The possibility of having got rid of Pump for Medium and Small Power Generating Set use rotary propeller type.
Summary of the invention
Task of the present utility model is to avoid the above-mentioned deficiency of prior art, a kind of external water pump, water turbine blade servomotor are provided, it has avoided river oil pollution, and volume little, be convenient to keep in repair, do not influence the conveyance capacity of runner, and make Pump for Medium and Small Power Generating Set also can use rotary propeller type.For realizing this purpose, the technological scheme that the utility model is taked is: with the blade servomotor by being moved to the generator outer end in the web, make it near the lubricant receiver position, operating oil pressure is brought up to 16Mpa-20Mpa by traditional 2.5Mpa-6.3Mpa, lubricant receiver like this, blade servomotor and corresponding pipeline size all can descend greatly, this provides structural possibility for exteriorization, the servomotor main shaft of outer postpone is connected with transmission shaft, control runner blade unlatching or close, the lubricant receiver diameter is minimum, all adopt the manufacturing process and the technology of high oil pressure hydraulic pressure components and parts, its seepage oil mass is minimum, lubricant receiver is connected by cutting the shake connector with blade servomotor main shaft, to avoid the common jumping swing of main frame to the piston of lubricant receiver, cutting the shake connector is made up of many groups leaf spring and two groups of Oil Guide flexible pipes, two fuel supply chambers of lubricant receiver respectively with the shock absorbing connector in two Oil Guide soft pipe connections, the other end of two Oil Guide flexible pipes is communicated with two oil circuits in the servomotor main shaft respectively, two oil circuits lead to two mutual disconnected working oil chambers of servomotor respectively, the outer pressure oil that supplies feeds two working oil chambers respectively through above-mentioned two oil circuits, the external oil sump tank that is fixed with of servomotor cylinder has further been got rid of the possibility of leakage of oil.Because servomotor is outside web, pressure oil can not enter runner inside, by blade leak downstream, the problem of oil extraction then can eradicate, same reason, make that maintenance is very convenient, owing to carried operating oil pressure, it is very little that the volume of servomotor and lubricant receiver is made, so Pump for Medium and Small Power Generating Set also can be used rotary propeller type.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the lubricant receiver in the utility model structural drawing and the enlarged diagram of shock absorber.
Embodiment
At external water pump shown in Figure 1, water turbine blade servomotor is made up of lubricant receiver 1 and servomotor 4, the housing of lubricant receiver 1 is fixed motionless, lubricant receiver piston 2 is connected with servomotor main shaft 5 by shock absorbing connector 10, and be synchronized with the movement with it, pressure oil from speed regulator passes through oil suction chamber a and oil suction chamber b, the inside hole slot of lubricant receiver piston 2, Oil Guide flexible pipe 8 and Oil Guide flexible pipe 9, two oil circuits in the servomotor main shaft are sent to two mutual not the working oil chamber A and the working oil chamber B of UNICOM respectively, the piston 7 of servomotor is fixed on the servomotor main shaft 5, servomotor main shaft 5 is affixed with transmission shaft 3, transmission shaft 3 is connected with the blade of runner again, and the cylinder body outer fixing of servomotor 4 has oil sump tank 6.During work, operation lift one head along with water pump, water turbine, when operating modes such as aperture changed, the angle of runner blade needed correspondingly to be changed, and this variation is by external servomotor 4, lubricant receiver 1, cuts parts such as shake connector 7, transmission shaft 3 and finish jointly.Because the miniaturization and the exteriorization of lubricant receiver, servomotor and be aided with high-precision processing technology, system is accepted in complete collection, leakage of oil, be convenient to safeguard, guarantee that turbine oil can not enter runner inside, owing to improved operating oil pressure, simplify the structure, reduced volume, reduced cost, the most important thing is to eradicate the oil pollution of equipment the river, downstream.
