6.3 Type inspection
6.3.1 Type inspection of reducer
6.3.1.1 For various types of new products of reducers and products produced by transferred factories or when there are major changes in materials, structures, and processes, type inspection must be carried out with no less than two prototypes. Only after passing the inspection can the products be finalized and put into batch production. 6.3.1.2 Carry out the reducer type inspection on a dedicated reducer type test bench. Carry out in accordance with the provisions of 6.2. In the absence of a dedicated reducer type test bench, the reducer type inspection will be completed when the whole machine type inspection is completed. 6.3.2 Whole machine type inspection
For various new types of beam pumping units and products produced in transferred factories or when there are major changes in materials, structures, and processes, type inspections must be carried out on no less than two prototypes. Only after passing the inspections can they be finalized and put into mass production. 6.3.2.1 The whole machine type inspection is divided into two categories: rated value inspection and over-rated value inspection, both of which are carried out under the condition of hanging heavy objects at the suspension point. The rated value inspection requires that the product be operated for a specified time under the rated suspension point load, rated torque of the reducer, maximum stroke, and maximum stroke times. Two or more rated values cannot be reached at the same time under one inspection parameter, but can be reached separately under multiple inspection parameters. The over-rated value inspection only requires the product to operate at a state of 25% over-rated suspension load and 25% over-rated torque of the reducer. When the reducer has completed the operation of 125% of the rated torque in Table 9, the operation of 25% over-rated torque of the reducer can be exempted in the whole machine type inspection. 6.3.2.2 Before the whole machine type inspection, the inspection parameters of the rated value inspection and over-rated value inspection shall be calculated and selected. If the product has m types of strokes and n types of strokes, there are m×n types of stroke combinations, that is, there are m×n types of type inspection parameters. Under the premise of not exceeding the rated suspension load and not exceeding the rated torque of the reducer, each type inspection parameter shall have data such as the mass of the hanging object and the reasonable balance position.
Select the best inspection parameter from the n×\ types of type inspection parameters as the inspection parameter for the whole machine type inspection. The selection shall meet the following requirements:
a) In one inspection parameter, the suspension load and reducer torque reach or approach the rated value at the same time, and the operation time is required to be not less than 100h.
b) When the rated value of the sensing point load or the reducer torque is reached or approached in the two test parameters, the operation time of each test parameter shall be not less than 100h.
e) When the operation does not include the maximum stroke under a) or b) conditions, the maximum stroke operation test shall be carried out, and the suspension point load and reducer torque may not be limited. The operation time shall be not less than 1h. d) When the operation does not include the highest stroke under a) or b) conditions, the highest stroke operation test shall be carried out, and the suspension point load and reducer torque may not be limited. The operation time shall be not less than 1h8
SY/T 50442000
e) When the test of exceeding the rated suspension point load by 25% and exceeding the rated torque of the reducer by 25% cannot be achieved at the same time under the conditions of the two test parameters, it can be achieved separately in the two test parameters, and the operation time of each test parameter shall be handled as appropriate. The whole machine type test parameters of a product shall be at least two and at most six. 6.3.2.3 The whole machine type inspection shall include the inspection items of 5.7, 5.8 and 5.22 in addition to the inspection items of 6.4.2 and 6.4.3. The calculation method of the suspension point load and the net torque of the reducer is shown in Appendix B (the appendix of the reminder). 6.4 Factory inspection
The beam pumping unit shall be inspected by the quality inspection department according to the following items before leaving the factory. It can only leave the factory after meeting the requirements. 6.4.1 Each beam pumping unit shall be inspected for no-load and load of the whole machine. For the no-load inspection of the front type, no heavy objects need to be hung at the suspension point: the no-load inspection of other types is carried out without balance blocks on both sides of the crank. At this time, if the machine cannot run continuously due to imbalance, appropriate weights can be hung at the comfort point to balance it so that the whole machine can run continuously. The running time of the no-load test is not less than 1hs
Before the load test, if there is no test parameter that can satisfy the base load and reducer torque to reach or approach the rated value at the same time, the load test can be carried out under the test parameters that only meet the full load of the suspension point load. The running time is not less than 2h. The strokes of the no-load test and the load test are not limited. 6.4.2 The beam pumping unit shall be inspected one by one according to the requirements of 5.3, 5.9, 5.11, 5.16, 5.17, and 5.18. 6.4.3 When the beam pumping unit is sampled according to the requirements of 5.12, 5.15, 5.19, 5.20, and 5.21, it shall be carried out in accordance with GB/T2828, using a normal inspection sampling plan, the inspection level is II, and the qualified quality level AQL is not greater than 2.5, and the product batch quality inspection shall be carried out. 6.5 Judgment rules
During factory inspection, each item should be inspected one by one. If any item fails, the product will be judged as unqualified; for random inspection, the sampling plan in GB/T2828 should be found out based on the batch photos, and the qualification of the batch should be judged based on the number of unqualified products in the sample. During the type inspection, if one unit or one item fails to meet the requirements, it will be judged as unqualified.
