Abstract
The utility model relates to a hydraulic turbine fixed guide vane connection structure, through at the pinhole that design position diameter corresponds on the ring sum stator under, of fitting with a contraceptive ring, with the round pin run through the pinhole make fit with a contraceptive ring, down ring sum stator fixed connection leave out the process time and the stock of equipment together, not only reduce equipment cost and drop into, convenient operation is swift in addition.
Description
Technical field
The utility model relates to a kind of water turbine fixed guide vane linkage structure, belongs to water turbine production and processing field.
Background technique
At present, the fixed guide vane of Francis turbine is all linked together by welding manner and upper ring and a lower ring, although the method is simple but the range accuracy between adjacent guide vane controls by the operation technique of workman completely, inspection is difficult to pinpoint the problems, simultaneously, the water turbine of same model sometimes needs the water turbine preparing different openings degree, the method of traditional welding formula needs several opening degree just to need to prepare several equipment, add the quantity in stock of equipment greatly, a large amount of heats is easily produced due to during welding, upper ring and a lower ring is easily out of shape, produce stress, welding Shi Han road also can affect water amount.
Model utility content
The technical problems to be solved in the utility model is to provide a kind of water turbine fixed guide vane linkage structure, by the pin-and-hole that design attitude diameter in upper ring and lower ring and stator is corresponding, pin being run through pin-and-hole makes upper ring and lower ring and stator be fixed together, eliminate equipment process time and quantity in stock, not only reduce cost of equipment to drop into, and convenient to operation.
For overcoming the above problems, concrete technological scheme of the present utility model is as follows: a kind of water turbine fixed guide vane linkage structure, comprise guide vanes of water turbine, upper ring and a lower ring, upper ring and lower ring and guide vanes of water turbine upper-end surface are equipped with pin-and-hole corresponding to the corresponding size in position, pin-and-hole runs through the upper and lower end face of upper ring and lower ring and guide vanes of water turbine respectively, be provided with fixing pin in pin-and-hole, fixing pin runs through pressed on ring, guide vanes of water turbine and lower ring from top to bottom successively.
Preferably, described pin-and-hole is uniformly distributed one week, and pin-and-hole one week distribution number is identical with guide vanes of water turbine number, and pin-and-hole is arranged in pairs, and two pin-and-hole central point lines on guide vanes of water turbine end face overlap with guide vanes of water turbine kernel of section line.
The beneficial effect that the utility model brings is: by the pin-and-hole that design attitude diameter in upper ring and lower ring and stator is corresponding, pin being run through pin-and-hole makes upper ring and lower ring and stator be fixed together, eliminate equipment process time and quantity in stock, not only reduce cost of equipment to drop into, and convenient to operation.
Accompanying drawing explanation
Fig. 1 is the structural representation of water turbine fixed guide vane linkage structure.
Fig. 2 is the plan view of Fig. 1.
Wherein, 1-guide vanes of water turbine, 2-pressed on ring, ring under 3-, 4-pin-and-hole, 5-fixing pin.
Embodiment
As depicted in figs. 1 and 2, a kind of water turbine fixed guide vane linkage structure, comprise guide vanes of water turbine 1, pressed on ring 2 and lower ring 3, pressed on ring 2, lower ring 3 and guide vanes of water turbine 1 upper-end surface are equipped with pin-and-hole 4 corresponding to the corresponding size in position, pin-and-hole 4 runs through the upper and lower end face of pressed on ring 2, lower ring 3 and guide vanes of water turbine 1 respectively, be provided with fixing pin 5 in pin-and-hole 4, fixing pin 5 runs through pressed on ring 2, guide vanes of water turbine 1 and lower ring 3 from top to bottom successively.
Preferably, described pin-and-hole 4 is uniformly distributed one week, and pin-and-hole 4 one weeks distribution numbers are identical with guide vanes of water turbine 1 number, and pin-and-hole 4 is arranged in pairs, and two pin-and-hole 4 central point lines on guide vanes of water turbine 1 end face overlap with guide vanes of water turbine 1 kernel of section line.The pin-and-hole 4 that design attitude diameter is corresponding on pressed on ring 2, lower ring 3 and guide vanes of water turbine 1, fixing pin pin 5 being run through pin-and-hole 4 makes pressed on ring 2, lower ring 3 and stator 1 be fixed together, eliminate equipment process time and quantity in stock, not only reduce cost of equipment and drop into, and convenient to operation.
Above-described is only preferred embodiment of the present utility model.It should be pointed out that for the person of ordinary skill of the art, under the prerequisite not departing from the utility model principle, some modification and improvement can also be made, also should be considered as belonging to protection domain of the present utility model.
