The rotation of itself, also inevitably it is being axially moved within the specific limits along it.Therefore propeller shaft sealing except
The aging of own material, the rotation of propeller are extremely complex to the abrasion that sealing is brought.The lower water of the work of sealing simultaneously
Under, huge hydraulic pressure and complicated abrasion environment so that theoretically can not accurately calculate the abrasion of sealing.
Therefore, a kind of detection means for the sealing test that can simulate sealing applying working condition peculiar to vessel is needed at present.
The content of the invention
It is an object of the invention to provide a kind of detection means of sealing test.
To reach above-mentioned purpose, the technical solution adopted by the present invention is：
A kind of detection means of sealing test, including internal there is cavity and the experiment cavity of one end open, be arranged on institute
The sealing frock of the openend of experiment cavity is stated, the dummy shaft being arranged in the test cavity body is horizontally rotated, is arranged on the examination
The detecting element of pressure in test chamber on cavity is tested, and is arranged on the tank being used for below the experiment cavity, institute
State and be provided with water inlet and delivery port on experiment cavity, sealing to be detected is set between the sealing frock and the dummy shaft
Part, the dummy shaft pass through from the shaft seal.
Preferably, the sealing frock is cylindrical shape, and its one end connects the openend of the experiment cavity, and the other end is set
The shaft seal.
It is further preferred that the sealing frock is detachably connected with the experiment cavity.
Preferably, the detecting element includes pressure sensor and pressure gauge.
Preferably, the dummy shaft through the drive shaft of the experiment cavity by driving its rotation, the drive shaft driving
The dummy shaft also drives the dummy shaft to be moved back and forth along its axial direction while rotation.
Preferably, the water inlet is arranged on the top of the experiment cavity.
It is further preferred that it is additionally provided with air bleeding valve at the top of the experiment cavity.
Preferably, the delivery port is arranged on the bottom of the experiment cavity.
It is further preferred that the bottom of the experiment cavity is additionally provided with the pressurize for maintaining the experiment cavity pressure stability
Valve.
Preferably, the scale of instruction wherein water is provided with the tank.
Because above-mentioned technical proposal is used, the present invention has following advantages compared with prior art：
Because the present invention is by testing the pivoting friction under cavity simulation water under different hydraulic pressure operating modes between dummy shaft and sealing, energy
Enough largely underwater abrasion conditions of simulation sealing.
While rotation due to the drive shaft driving dummy shaft of the present invention, also drive dummy shaft to be moved back and forth axially, simulate spiral shell
Movement locus when paddle shaft real work is revolved, to test the abrasion condition of sealing.
Due to the present invention experiment cavity be provided with tank, by measure from test cavity leakage water can count
Calculate the abrasion condition of sealing.
