Abstract
The utility model relates to a cylinder-action type runner test tool which comprises an upper part cover board, a middle part cover board and a lower part cover board. A high pressure fuel pipe is connected between the middle part cover board and the lower part cover board, and the high pressure fuel pipe is provided with a pipe joint. The runner test tool is characterized in that a mounting plane is processed in the central hole of the a servomotor cylinder cover; the upper part cover board is mounted on the plane and is in tight connection with the servomotor cylinder cover through a joint bolt; a spigot playing a positioning role is arranged at the lower end of the middle part cover board and the spigot is inserted in the central hole of a piston; the middle part cover board is in tight connection with the piston through a joint bolt; and the lower part cover board and a runner hub are fixedly connected through a joint bolt matched with a technical screw hole formed on the lower end surface of the runner hub. The utility model has the advantages of simple structure, good sealing performance, convenient processing and installation as well as light entire weight, and the cost is reduced and the resource is saved at the same time.
Description
Technical field
The utility model belongs to the water wheels set of equipments and makes the field, particularly relates to a kind of cylinder moving type runner test frock.
Background technology
Runner test frock is must be indispensable in hydraulic generator unit manufacturing engineering, and it is used for detecting the impermeability test of two pressure chambers of servomotor cylinder and the action test of runner.Generally adopt in pressure chamber to feed hydraulic oil and test, runner test frock mainly comprises compositions such as cover plate, hold-down bolt, steel pipe, joint.Traditional is designed to: big and thick and heavy with the design of upper and lower cover plate, bottom cover plate are connected with screw on the web core by special 4 king-bolts and compress, and the top cover plate is established inner stopper and positioned.Said method design experiment tool structure complexity, weight is heavier, because the screw on the web core is to be used for connecting web and web core, this place's screw is generally more than M64, so compress the bolt cost of bottom cover plate higher (generally more than M64X300); The top cover plate increases thickness owing to be provided with darker inner stopper.Because runner test frock does not just re-use after the installation of power station only in the usefulness of preinstallation, so traditional method for designing has just caused the waste of manpower and resource, has improved manufacturing cost.
Summary of the invention
The utility model provides a kind of simple in structure, processing and easy for installation, in light weight, with short production cycle for solving the technical matters that exists in the known technology, and reduces the cylinder moving type runner test frock that generates this.
The technical scheme that the utility model is taked for the technical matters that exists in the solution known technology is:
A kind of cylinder moving type runner test frock, comprise the top cover plate that is installed in servomotor cylinder cap central hole, the middle part cover plate that is connected with piston, the bottom cover plate that is connected with web, the high-pressure oil pipe that is connected between middle part cover plate and the bottom cover plate, pipe adapter that the outside high pressure oil pipe of bottom cover plate is provided with and the pipe adapter that is communicated with web core center pit, it is characterized in that: describedly be processed with a mounting plane in servomotor cylinder cap central hole, the top cover plate is installed on the plane, and is fastenedly connected by coupling bolt and servomotor cylinder cap; The lower end of middle part cover plate is shaped on the seam that plays the role of positioning, and seam is inserted in the piston center hole, and the middle part cover plate is fastenedly connected by coupling bolt and piston; Fastening between bottom cover plate and the web by the coupling bolt that cooperates with technology screw that the web lower surface has.
The utility model can also adopt following technical measures:
Be provided with O-ring seal between described top cover plate and the mounting plane.
Be provided with O-ring seal between the seam of described middle part cover plate and the piston hole inwall.
Be provided with O-ring seal between described bottom cover plate and the web.
Advantage and the good effect that the utlity model has are: because the utility model, cancellation top cover plate inner stopper, outer round mounting plane location, thickness, processing capacity and the weight of minimizing top cover plate; The place sets up the technology screw at the bottom cover plate, special forging king-bolt in the cancellation traditional design, compress the bottom cover plate by plain bolt, simultaneously the bottom cover plate is designed to the total amount that minor flaps has alleviated whole frock, therefore the utility model is simple in structure, installation and processing is convenient, total amount is light, reduces cost simultaneously, economizes on resources.
