Embodiment Construction
[0013] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0014] The working condition test device of the intelligent pumping unit in the embodiment of the present invention, in figure 1 Among them, the fixed shaft pulley 2, the deflection pulley 3, and the counting pulley 4 are fixed on the body 1 in a triangular distribution, and the deflection pulley 3 can rotate 90 degrees around the deflection axis 7, and thrust against the thrust block 5 when it deflects downward. Test The front deflection pulley 3 deflects 90 degrees upwards, so that the wire rope passes through without unloading. The strain gauges 6 are symmetrically distributed on the sensor body and are used to calculate the load.
[0015] exist figure 2 In the shown embodiment, the test device is in the test state, the deflection pulley 3 deflects downward ...
