This standard is revised from SY/T5212-1997 "Quality Classification of Beam Pumping Units" based on the technical content specified in SY/T5044-2000 "Beam Pumping Units". The contents of the donkey head suspension point projection, the difference between the two crank scissors, the longitudinal amplitude of the bracket top, the lateral amplitude of the bracket top, the position of the beam, the position of the bracket top, the determination of the operating parameters of the whole machine performance test, and the donkey head suspension point projection test method have been unified and necessary modifications have been made.
This standard will replace SY/T5212-1997 from the date of entry into force. Appendix A of this standard is the standard appendix.
Appendix B of this standard is the indicative appendix.
This standard is proposed and managed by the National Technical Committee for Standardization of Petroleum Drilling Equipment and Tools.

b) First class: Item group 3 is qualified: Item groups 1 and 2 are respectively excellent, first class (first class, excellent) or all are first class: e) Excellent: Item group 3 is qualified: Item groups 1 and 2 are all excellent. 3.2.1.3 Determination of operating parameters and operating time for the whole machine performance test. Before the whole machine performance test, the operating parameters should be calculated. Under the conditions of maximum stroke and rated suspension point load, the mass of the suspension point hanging weight corresponding to each stroke and the peak torque (maximum torque) with two peak torques equal to each other are calculated, and several groups of operating parameters (operating conditions) can be obtained. From several groups of operating parameters, the operating parameters with the largest peak torque but not exceeding the rated value are selected as the whole machine performance test operating parameters. If there are no operating parameters that meet the above requirements, the mass of the suspension point hanging weight should be reduced (the suspension point load should be reduced), and the operating parameters with the largest suspension point load should be recalculated under the conditions of maximum stroke and rated torque of the reducer. The group with the largest suspension point load is selected as the whole machine performance test operating parameters.
SY/T5212-—2000
The relative error between the calculated suspension point load, stroke, and stroke and the actual measured value shall not be greater than 5%. The continuous operation time shall not be less than 3h under the required operating parameters. 3.2.1.4 The test methods for some items of the whole machine performance test are shown in Appendix A (Appendix to the standard). 3.2.2 The quality of main parts and appearance is divided into quality grades according to the qualified rate of sub-item categories (see Table 3), and then its comprehensive quality grade is determined.
