Warp testing device used for pump connecting rubber hose

Abstract

The invention discloses a warp testing device used for a pump connecting rubber hose. The warp testing device comprises a controller, programmed high and low temperature boxes, a plurality of supports, a plurality of rotating shafts and a drive device, wherein the supports are arranged in the programmed high and low temperature boxes respectively and arranged at intervals, the rotating shafts are connected to the supports in a rotating mode, and the drive device is used for driving the rotating shafts to rotate. The rotating shafts are provided with torque sensors respectively. A tension spring is arranged between every two rotating shafts in the peripheral direction. The rotating shafts are provided with arc-shaped grooves used for containing the tension springs. The drive device comprises a motor, a first gear and a second gear, wherein the first gear and the second gear are installed on an output shaft of the motor, and the second gear is meshed with the first gear. The torque sensors and the motor are electrically connected with the controller through connecting lines. The other end of the pump connecting rubber hose is connected to a piston rod of an air cylinder. The warp testing device used for the pump connecting rubber hose is simple in structure, and the testing structure is more real and effective.

Description

technical field [0001] The invention relates to the field of pipe fitting testing, in particular to a twist testing device for pump-connected rubber hoses. Background technique [0002] The pump is connected to the rubber hose, which is very important for the pipeline connection. Improper selection of the crimping amount and crimping speed when assembling the rubber hose and the joint, or unreasonable selection of the structure, material, and size of the joint can cause the hose and joint to be over-tightened or over-pressed. Loose, causing early damage to the joint. Therefore, the torsion test about the pump-connected rubber hose is very important, but the problem is that the torsion test of the prior art is very simple, and the torsion situation of the actual working condition is far more complicated than that simulated by the test device of the prior art, such as when the metal When the torque of the joint part and the rubber hose part is uneven, the twisting result cann...

[0002] The pump is connected to the hose, which is very important for the pipeline connection. Improper selection of the crimping amount and crimping speed when assembling the hose and the joint, or unreasonable selection of the structure, material, and size of the joint, can lead to the hose and joint being over-tightened or over-pressed. Loose, causing early damage to joints

Therefore, the torsion test about the pump-connected rubber hose is very important, but the problem is that the torsion test of the prior art is very simple, and the torsion situation of the actual working condition is far more complicated than that simulated by the test device of the prior art, such as when the metal When the torque of the joint part and the rubber hose part is uneven, the twisting result cannot be expressed, and the same is a metal pipe joint, and the torsional force suffered by the front part and the middle part with the outer hexagonal part is also different. The twisting test of the prior art The device cannot guarantee the authenticity and validity of the test results
