The invention further discloses a detection system of the load and displacement integral wireless indicator of the belt type pumping unit. The detection system comprises the load and displacement integral wireless indicator, a ground receiving and processing unit and a computer connected with the ground receiving and processing unit. The load and displacement integral wireless indicator of the belt type pumping unit and the detection system of the load and displacement integral wireless indicator are simple in structure, convenient and rapid to detect, safe and reliable and low in power consumption. Besides, the load transducer is corrected and calibrated automatically through the computer, a zero-regulator resistor is not needed to be arranged externally, and simultaneously, system working and hibernation time can be set in real time manually.

Description

technical field [0001] The invention relates to an integrated wireless sensor for detecting the load and displacement of an oil pumping unit, in particular to an integrated wireless dynamometer for the load and displacement of a belt-type and chain-type oil pumping unit. [0002] The invention also relates to a load and displacement integrated wireless dynamometer detection system for belt-type and chain-type oil pumping units. Background technique [0003] Belt-type and chain-type pumping units are a purely mechanically rotating chain-belt pumping unit, especially suitable for large pumps with rod pumps to extract liquid, small pumps for deep pumping, and heavy oil exploitation. It represents the development of pumping units. direction. At present, the method of testing the dynamometer diagram of the belt or chain pumping unit is: install a load sensor at the connection of the rope hanger of the polished rod to measure the load of the polished rod; install a linear displac...

AI Technical Summary

Problems solved by technology

[0005] The deficiencies in the test method of the existing dynamometer above are: 1. The installation position between the load sensor and the sensor for measuring the displacement of the polished rod is far away. If the wired transmission method is adopted, the required cable is longer. The way of wireless transmission needs to solve the power supply and other problems, and the installation and setting of each sensor are more troublesome; 2. The load sensor, the sensor for measuring the displacement of the polished rod, and the connected cables are in a moving state during the test, and the sensor equipment and cables are easily damaged. Damage, seriously affecting test reliability and test accuracy

3. In belt-type and chain-type pumping units, the load sensor and the displacement sensor still have to be installed separately, and the load and displacement cannot be combined to realize the dynamometer diagram of the test load and displacement.
