5.1 Test method
5.2 4.1., 4.12.4.1.4.4..5.4.1.7-4.1.54.2.3.2.54.3.9 of this standard shall be tested according to the requirements of G18422. 6 Inspection rules
6.1 Inspection classification
Road roller inspection is divided into "inspection" and "type inspection". 6.1.1 Factory Inspection
Layer thickness-cm
The pressure reducer shall be inspected by the quality inspection department of the manufacturer according to the technical standards, and can only be released after the relevant products are released; "Output inspection" includes the following contents:
Electric running inspection:
Brake inspection:
Motor inspection;
Transmission, power supply inspection of the system such as the transmission, the waterway, etc. Appearance inspection.
6.1.2 Frequency conversion
The type inspection of the pressure reducer includes the performance test and the reliability test (or 4Uh industrial test). The type inspection shall be carried out in the following circumstances:
New products or old products! Production trial production After production, the structure, materials, and process are slightly changed, which may affect the product performance.
7 Sampling
When the national quality supervision agency proposes the requirement of type inspection, the roller to be inspected shall be sampled by the movement block method: a suitable inspection sample. B Judgment Rules
51 When all the inspection items of the roller factory meet these requirements, the product is judged to be qualified: it is determined to be unqualified, and the factory inspection will be carried out according to the method of whether it is qualified or not. Table 6
Qualified requirements
Idle running confirmation
Special dynamic inspection
The whole environment test should be briefly required for each room to be carried out, and the case should be included in the normal sequence, and it cannot be producedbzxz.net

Meanwhile, the requirements are as follows:
The standard is that the air is vibrated quickly or for 10 minutes. There shall be no need to calculate the need. The bearing seat does not have an overheating rate that meets the requirements of Article 4.1.2 and the requirements of Article 4.2.3 and the requirements of Article 4.2.9.
Daily.3 life control test. The stopper does not meet the requirements of the standard screen (4.1.1, 2.1.3.4.1.4~4.1.6.4.2.8.4.1.52 and 4.2.3, 4.2.5.4.2.9): If one of the requirements is met, it is judged as a substandard product. 8.4 If the product meets the requirements of the production standard after inspection, but there are 4 or more samples that do not meet the requirements of the duplicate standard, it is also judged as a non-conforming product.
