The invention relates to a reciprocating friction-wear testing machine for rod and tube parts. According to the invention, a variable-frequency three-phase asynchronous motor is used for providing power for a friction-wear test, a variable-stroke disc is connected with a speed reducer, a connecting rod and a sliding rod, and rotary motion of the variable-frequency three-phase asynchronous motor is converted into linear reciprocating motion. A stepping motor is connected with a pipe fitting clamp through a loading speed reducer and a lead screw nut and controls the pipe fitting clamp to move in the vertical direction so as to provide loading force, a rod piece clamp is provided with a rod part needing to be tested and is connected with the sliding rod to do reciprocating linear motion in the horizontal direction, and a spraying system provides a liquid environment for a friction wear test. A heating rod controls the temperature of a solution, the solution is sprayed to a friction test piece by a water pump through a spraying head, a computer serves as a man-machine interaction platform, test parameters are set, test data are collected, a control system receives instructions of the computer to control the test environment, and a detection system is a sensor for collecting the test data. Friction and wear tests can be carried out on actual rod and tube parts in an actual working environment, various working environments can be simulated, and the automation degree is high.
Description
technical field [0001] The invention relates to the technical field of eccentric wear of oil well rods and tubes, in particular to a reciprocating friction and wear testing machine for rods and tubes. Background technique [0002] The friction and wear of rod and tube parts often occurs in machinery. There are rod pumps in oil fields and drilling operations will cause wear. If it is too large, damage will seriously affect production and life, so it is very important to study the wear of rod and tube parts under real working conditions. [0003] The traditional friction and wear testing machine has certain deficiencies. It can only carry out the friction and wear test of rod and tube parts materials, and cannot directly simulate the real working conditions of rod and tube parts, and the degree of automation is low. Aiming at the above problems in the existing technology, the present invention proposes a reciprocating friction and wear testing machine for rod and tube parts, ...
