Description

Simulation test bed

Technical Field

The utility model relates to the technical field of test benches, in particular to an analog test bench.

Background

In scientific research, the dynamic simulation test bed can complete the following tasks that (1) before an engine performs a real test, the dynamic simulation test of an aeroengine control system can be firstly performed so as to ensure the safety and reliability of the engine during the test; (2) when various control schemes are researched, a test can be carried out on a dynamic simulation platform so as to predict the result of an engine during testing; (3) sometimes even tests that are difficult to perform on an engine can be performed on a dynamic simulation bench.

The pumping unit is the most commonly used ground equipment for oil extraction in oil fields, and the control mode of the pumping unit comprises two modes of power frequency and variable frequency. However, due to the complex variability of the well conditions of the oil well, if the oil pumping unit is operated at the power frequency all the time, the output of the oil well can be affected, unnecessary energy consumption can be increased, the cost is increased, and the economic benefit of enterprises is reduced.

Furthermore, since the well conditions vary greatly from well to well in the production site, if well field debugging is to be performed, it is necessary to test the different wells. If so, not only can the testing of all the well conditions which possibly occur be completely realized, but also if the oil well is replaced continuously, great inconvenience is brought, the normal operation of the oil extraction work is also influenced, and the oil extraction yield is seriously influenced, which is not allowed by an oil factory.

In the process of using the pumping unit, the polish rod sealer can be used, but the current polish rod sealer is lack of inspection, so that errors easily occur in the subsequent use, and the effect and the service life are affected. In view of this, we propose a simulation test stand.
