415 Quality assurance
When the user complies with the conditions of maintenance, use, storage, installation, this is given to the blessing, the product is suitable! Agricultural goods are used for more than twelve months, due to poor manufacturing quality, dust damage or failure to work properly, it is a serious problem! 5. Test methods
5.1 Test bearingWww.bzxZ.net
5.1.! The winch shall be subjected to various tests at rated voltage (difference is 5%). 5.1.2 The instruments and meters used in the test shall be accompanied by a valid certificate or periodic identification certificate. 5.2 Operation performance test
5. 21 Empty gear test
The winch shall be operated in both forward and reverse directions for 30 minutes, and the movement of each part shall be observed, such as sound, plate movement, and demand. 5.2.2 Overload test
The vehicle is loaded with 25%, 50% or 75% of the rated load and continuously runs forward and reverse for 25 seconds under the rated load. During the operation, observe the movement of the parts, noise, vibration, temperature, etc. 5.7.3 Overload test
The overload test is carried out after the load test. The load is 12% of the rated load. The test lifting times are not less than 3 times. The ionization of each operation should not be less than 8 meters:
5.2.4 Sealing inspection
The micro-inspected medium is put under the clean room for inspection. 5.2.5 Noise test
When the test object is under load, the noise generation test is carried out according to (B3763, 5.2.6 Temperature test
After the load test, the vehicle is checked with a temperature meter at the oil channel bearing. Use the end 11 for detection. 5.2. 7 Cleanliness test
After the winch no-load test, the speed of the reducer has been tested according to B11368. 5. 2.8 Copper wire rope speed test
Use photoelectric sensor and photoelectric oscilloscope to carry out photoelectric method, and tachometer can be used for measurement. 5.2.9 Static tension test of wet wire braid
Use a tension meter with an accuracy of not less than level 2, connect it between the steel body and the load for a scratch test. 5.3 Braking performance test
The braking performance test is carried out during the load test, and the operation is not less than 3 speeds. Inspection regulations
