Abstract
The utility model relates to a sealing connecting device, which is specifically used for a controllable pitch propeller shell seal test and discloses a push-pull rod type controllable pitch propeller seal test equipment. The push-pull rod type controllable pitch propeller seal test equipment comprises a fixing clamp ring and a pump pressure cylinder; the fixing clamp ring is dismountablely mounted on the outer circumference at the head end of the propeller shaft, and is connected with the pump pressure cylinder; the pump pressure cylinder is communicated with the cavity of the propeller shaft and the other end of the pump pressure cylinder is provided with a connector for connecting an oil pump. The push-pull rod type controllable pitch propeller shell seal test equipment is capable of mounting a propeller vane on the propeller shaft with a propeller shell in the shipyard workshop. Test on the sealability of the propeller shell can be carried out without needing to connect an intermediate shaft and an oil distribution shaft; the workload of mounting is small; meanwhile, problems brought by the propeller sealability test of the manufacturer can be avoided, thereby better guaranteeing the mounting quality of the controllable pitch propeller and the construction period of the slipway.

1. after arriving the shipyard workshop, blade is installed on the oar shell,, need after building berth links into an integrated entity propeller shaft, intermediate shaft, oil distribution shaft, to carry out oar shell tightness test again for checking the blade sealing.If tightness test is defective, then must reinstall blade at building berth.
2. building berth construction environment condition is relatively poor, should not carry out the hydraulic part assembly work.
3. in addition, ressemble blade and close examination, also will increase building berth installation workload and construction period.
The utility model content
Technical problem to be solved in the utility model provides a kind of tuning for Controllable Pitch Propeller oar shell leakage test equipment, and it has the advantages that to carry out oar shell tightness test in the shipyard workshop.
For solving the problems of the technologies described above, a kind of tuning for Controllable Pitch Propeller oar shell leakage test equipment that the utility model provides, it is characterized in that: comprise fixedly snap ring, pump pressure tube, described fixedly snap ring detachably is installed on the excircle of propeller shaft head end, and is connected with described pump pressure tube; Described pump pressure tube communicates with the screw propeller axocoel, and the other end of pump pressure tube is provided with the joint that is used to connect oil pump.
Advantage of the present utility model is:
1. can carry out oar shell tightness test in the shipyard workshop, the construction environment condition will be got well than building berth, and is guaranteed to the product installation quality.
2. can in the shipyard workshop, blade be installed on the propeller shaft of band oar shell, do not need intermediate shaft, oil distribution shaft are connected, can carry out oar shell tightness test, installation workload is little, the problem brought by manufacturing plant's oar shell tightness test at building berth can be avoided simultaneously, thereby the installation quality and the building berth construction period of tuning for Controllable Pitch Propeller can be better guaranteed.
The utility model is simple in structure, easy to make, be easy to install, cost is low, simple to operate, result of use is good, can satisfy the requirement of oar shell tightness test, can be applied to similar tuning for Controllable Pitch Propeller oar shell tightness test.
