zero pitch setting, full positive pitch and full reverse pitch shall be determined; the pitch adjustment time of the full positive car to the full routine car (and vice versa) under the retrospective transfer shall be measured to verify various operation methods:
other pitch adjustment function indicators, heat generation design indicators shall be verified: during the entire use of the explosion distance, the power shaft speed, ship speed and the relationship between the parameters of the necessary test items shall be checked! Speed test:
emergency stop and emergency reverse, positive sailing test, and the device test for the fixed pitch beam shall be carried out. The inspection rules
the pitch adjustment manufacturer shall complete various tests and inspections in the following order before submitting them to the registration certificate, and submit the corresponding test report and a copy of the qualification certificate.
7.1 Component inspection
The component inspection report shall include the following:
Material Chemical composition and mechanical properties test report of materials: h.
Test report of ultrasonic, carbon powder and color: c.
Hydraulic strength test report:
Hydraulic pressure sealing test report:
Required (part) medical size inspection report:
Static balance inspection report:
Special inspection report as per drawing or test requirements. Physical inspection
7.2.1 If the equipment of adjustable pitch slurry (mainly refers to the electronic control system equipment) has one of the following conditions, type inspection shall be carried out: a.
New products or product conversion! Trial production, design, material and process modification, which may affect product performance: b.
Products produced in batches every 4 years.
7.2.2 Type inspection test items:
Appearance inspection:
b. Utility inspection,2. Navigation test conditions. The navigation test of the adjustable pitch propeller includes the test of the pitch adjustment itself and the ship speed test. After the mooring test of the adjustable pitch propeller is completed and approved: the propeller itself is considered to have the flexibility of the navigation test, but the test needs to be carried out at the same time in accordance with the sea conditions, ship speed, loading conditions, and engine conditions. The speed measurement method is the same as that of the ship with specified pitch. 6.7.3 Navigation test content;
Check the tightness of the joints of the hydraulic (and pneumatic) system. Check the accuracy of the pitch pointer under various working conditions: check the pitch position, interlocking pitch correctness, and the normal operation of the lubrication (flushing) system. Check the adjustment of the hydraulic and pneumatic systems and the overflow, flow valve, interlocking, and alarm work. The electronic control system and its linkage and coordination with other equipment shall be checked: the highest setting
zero pitch setting, full positive pitch and full reverse pitch shall be determined; the pitch adjustment time of the full positive car to the full routine car (and vice versa) under the retrospective transfer shall be measured to verify various operation methods:
