5.2.1 After the no-load test is passed, the load test can be carried out. At the provisional speed, the load test is divided into four steps. The rated load must be 256. Each load test must be balanced for 15 seconds before increasing the load level. 5.2.2 The load test results meet the following requirements: a) Each density is not different from the joint surface.
) The contact spots should meet the requirements of .7.5 and 4.7.6. ）The speed reducer should run smoothly and normally, without shock and abnormal noise. The temperature rise of the internal temperature of the speed reducer shall not exceed 45.

Full load test The power is increased to more than 90% of the rated power, and the continuous operation is more than 24h. The test results shall meet the requirements of 5.2 and 2. This test is allowed to be carried out in the field and according to the requirements of the host. 5.4 Load test
5.4.1 Overload test should be carried out together with the load test: Under rated speed, the overload test is carried out at 120% of rated speed for 1min, 150% for 1min, and 180% for 0.5min. 5.4.2 After the overload test, the reducer should meet the requirements of 5.2.3 and should be able to run normally. This test is allowed to be carried out at the host site and according to the host requirements.
5.5 Reduced life test
5.5.1 The industrial life test is to evaluate the service life of the turbine. It can be tested on the factory test bench. It is allowed to use industrial application test instead of industrial life test. However, it must be tested with the equivalent load cycle number under the actual load of industrial application, and there must be accurate records. The test time is not less than 3600h.
5.5.2 The reduced life test must be carried out after the test in 1.5.2 is completed. The test should be carried out under the specified load. The high-pressure cycle stress of the turbine should reach 210 working times. The load test should be carried out according to this time. 5.5.3 The test should be carried out under the specified load for not less than 60% of the industrial use. After the test, the requirements for the integrity of the speed machine are as follows: 1. The turbine and all machine parts are broken.
b) No bonding, heat damage.
