According to the pumping unit indicator diagram liquid production capacity measurement technology, the defects such as high cost, large operation difficulty and low measurement accuracy in the prior art can be overcome to realize the advantages of low cost, small operation difficulty and high ...
Then the time-frequency diagram is input as the feature map, and the CNN classifier model is established to realize the intelligent fault of the pumping unit. diagnosis. The results show that the method can effectively identify the fault type of the pumping unit and has a high recognition ...
The size of theballastvolume depends on the total quantity of gas to be pumped per unit of time. If this rate is very low, the rule of thumb indicates that 0.5 l of ballast volume allows 1 min of pumping time with the backing pump isolated. ...
The conditions of normal oil extraction, insufficient oil well liquid supply, breaking of a sucker rod, airlock phenomenon and the like can be analyzed and judged according to set parameters and collected indicator diagram data, and the pumping unit can be timely shut down in a linkage control ...
Figure 8. Simplified diagram for a passive pump (top) and operation principle of a passive valve (bottom). Passive pumps have used two different valve configurations: a single cantilever valve and a dual-diaphragm check valve, as shown in Figure 9. The cantilever valve, the most common valve...
FIG. 3 is a component diagram illustrating a cut-away perspective view of one implementation of an example double gear set pump 300. In this implementation, the respective parts of the pump are numbered according to the FIGS. 2a-2b. Further, FIG. 3 illustrates a first pumping chamber 260 ...
