Description
Technical field
The invention belongs to water turbine and make the field, particularly relate to a kind of Combinatory for adjustable blade propeller turbine.
Background technique
Lubricant receiver is a vitals of water turbine; it is a kind of a kind of change device that carries out the oil sources conveying by fixing housing through running shaft; be used for the high pressure oil of outside is injected respective inlets on the rotary main shaft continuously by static pipe-line system; and by this pressure oil operated piston mechanism action; adjust the rotation of water turbine blade, thereby reach the purpose of regulating unit load and startup-shutdown.Traditional Combinatory for adjustable blade propeller turbine and operating oil line are split-type structural, because operating oil line and main shaft are connected as a single entity, between lubricant receiver and operating oil line, need a connecting body (for example generator front end axle etc.) to be connected, complex structure, difficulty is installed, and be unfavorable for determining of length dimension.The oil tray seat and the lubricant receiver body of lubricant receiver all adopt cast structure, mfg. moulding die cost height, and the process-cycle is long; The interior pipe of operating oil line, middle pipe and outer tube are to be connected and composed through flange by the segmentation body, are the rigidity of strengthening operating oil line, and at several screws that queue supporting effect that are welded between tube wall inside and outside the operating oil line, its shortcoming is; Sealing is poor, occurs leakage of oil easily, and screw does not possess leading role.The lubricant receiver of water turbine adopts pulley to recover mechanism as it, and the motion state of water turbine paddle is fed back to speed regulator by the machine feedback system, so the sensitivity of machine feedback is low, and be not easy to determine the stroke neutral position of servomotor bring certain difficulty also can for simultaneously operation and processing with pulley structure.
Summary of the invention
The present invention for solve the technical problem that exists in the known technology provide a kind of simple in structure, be easy to process, strengthen lubricant receiver intensity and rigidity, feedback sensitivity is high and be convenient to install the Combinatory for adjustable blade propeller turbine of adjusting.
The technological scheme that the present invention takes for the technical problem that exists in the solution known technology is: Combinatory for adjustable blade propeller turbine, mainly comprise the operating oil line assembling, the lubricant receiver body, preceding fuel tank and recovery mechanism, it is characterized in that: described by interior pipe, the operating oil line assembling that middle pipe and outer tube constitute connects into an overall structure with the lubricant receiver body of seamless steel pipe system, on operating oil line assembling outer wall, be set with the sealing bearing bush fastening with the lubricant receiver seat, be fixed with change on the operating oil line assembling outer wall, the lubricant receiver seat connects the lubricant receiver body, unsteady watt and guide head are installed between operating oil line assembling and lubricant receiver body, unsteady watt is assembled interior pipe with operating oil line guide sleeve is set, lubricant receiver body one end is connected with preceding fuel tank, Guan Yiduan stretches into preceding fuel tank in the operating oil line, is connected with in operating oil line assembling inner tube portion and recovers mechanism; Described recovery mechanism is the swing link type structure, this recovery mechanism comprises: be installed in pipe one bearing at end seat and deep groove ball bearing in the operating oil line assembling, pipe flexibly connects the jaw that fork is installed on it in the operating oil line assembling, the fork lower end installs rotating shaft, fuel tank and pointer before fork connects by rotating shaft; Each section body of pipe, middle pipe and outer tube all connects and composes by thread head in the described operating oil line assembling, be provided with in the threaded connection place of each section body and prevent from the limiting stopper that becomes flexible to be fixed with guide pad and the limiting stopper that is used to play the guiding role, strengthen its rigidity and intensity and keeps coaxial rotation on pipe and the middle pipe outer wall in the operating oil line assembling; Described lubricant receiver seat is a welded-steel plate construction.
The present invention can also adopt following technological scheme:
Be provided with V-shaped seal ring between described operating oil line assembling and the guide head.
Described fork is by pin and jaw location.
Advantage and good effect that the present invention has are: the lubricant receiver body that the present invention makes operating oil line assembling and seamless steel pipe connects into an overall structure, operating oil line assembling outer tube need not generator front end axle and replenishes, this outer tube self length promptly is the outer length of tube that lubricant receiver needs, and then make its structure more simplify, be convenient to install, and help determining of length dimension, in the time of only need considering the water turbine paddle in standard-sized sheet and complete shut-down position when design, lubricant receiver also is in standard-sized sheet and length dimension is determined in the complete shut-down position.It is that seamless steel pipe is made that the lubricant receiver seat adopts welded-steel plate construction, lubricant receiver body, can shorten the process-cycle greatly like this, has saved the mould manufacturing expense, reduces cost and has increased the intensity of lubricant receiver.Each section body of pipe, middle pipe, outer tube adopts thread head to connect in the operating oil line, and install limiting stopper in each joint, and weld guide pad on interior pipe and the middle pipe outer wall, not only strengthened the rigidity and the intensity of operating oil line, it is loosening to avoid the joint to occur, and also can guarantee the operating oil line coaxial rotation.Between guide pad and operating oil line, adopt the V-seal structure, and then can avoid occurring leakage of oil.Recover mechanism and adopt the swing link type structure,, can be easy to determine the neutral position of paddle stroke like this by the position of fork by the motion of jaw and fork; In addition, more accurate because this recovery mechanism adopts electric liquid feedback than machine feedback, improved sensitivity.
