Description
Technical Field
The application relates to the field of petroleum drilling tools, in particular to a detection device and a detection method for a stator motor rubber bonding effect.
Background
In the oil and gas industry, screw drilling tools are important components in well drilling tools and play an important role in well drilling and oil and gas exploitation. However, during the drilling process, high-speed bearing friction between the rotor of the positive displacement motor and the rubber elastic body of the motor lining is always existed and inevitable, and the high-speed bearing friction is a severe test for the bonding strength between the motor shell and the rubber elastic body. Generally, stator motor manufacturers all adopt a simulation test piece to perform a bonding test, but the method has a plurality of uncontrollable problems as follows:
1. the vulcanization conditions of the simulated test pieces generally used for bonding are not in agreement with those in the production of the stator motor.
Due to the difference of the volumes of the workpieces and the difference of the processing technologies, the simulation test piece is adopted to simulate the bonding strength between the stator motor shell and the rubber elastomer, and the simulation test piece does not have the different furnace vulcanization conditions, so that the simulation bonding test has larger difference with the detection result of the bonding strength of the product.
2. The simulation test piece and the stator motor shell are not in the same adhesive coating mode.
The adhesive coating of the stator shell generally adopts methods such as brushing, spraying, dipping and the like, and the simulated adhesive test piece is limited by volume and shape and is essentially different from the stator shell in coating.
3. The stress condition of the test piece after the adhesive vulcanization is measured is different from the stress condition of the stator motor rubber during working.
According to the adhesive strength of GB/T7760-2003 vulcanized rubber and a hard plate, the peel strength of the adhesive vulcanized simulated test piece is measured, but the peel strength of the adhesive vulcanized simulated test piece is basically simulated to be peeled at a right angle of 90 degrees, and the stator motor rubber is mainly stressed by axial shearing force and has a certain curvature when in work.
Therefore, the method of measuring the peel strength by simulating the adhesion of the test piece cannot be used for measuring the adhesive strength of the rubber of the stator motor.
As described above, a detection device and a detection method capable of reliably reflecting the actual state of rubber adhesion are necessary and desired.
