The quality of rubber hose assembly directly affects the normal use of rubber hose, so it is necessary to pay attention to the quality inspection of rubber hose. The following is a brief introduction of how to judge the quality of rubber water pipe assembly from several aspects.

1. Rubber water hose assembly should pay attention to quality inspection.

Because the diameter of the rubber hose and the outer diameter of the skeleton layer are not strong, if the vibration scale exceeds the promised limit, the glue balance of the hose joint cannot be guaranteed, nor the quality of the hose assembly can be guaranteed. Therefore, in the production of rubber hose assembly, it is necessary to strictly check whether the inner and outer diameters of the structure layer meet the requirements.

2. Due to the pain of the rubber layer in the rubber water hose assembly and the influence of the width of the joint between the layers of the structure of the rubber hose quality testing center, the thickness error of the pipe wall is too large. If the wall thickness error exceeds the allowable range, it will affect the sealing ability and tensile strength of the rubber hose assembly, and even cause some bending of the joint of the rubber hose assembly. Therefore, the wall thickness error of the flexible rubber hose should be strictly controlled in the quality inspection. Generally, rubber hoses with wall thickness greater than 0.5mm should be strictly selected.

3. Should have a good integrity, that is, the quality inspection of the rubber hose: each structural layer should have a high adhesive force, a whole should be formed between the rubber layer, used to connect the device and the various technical requirements of the fastening process, can ensure the installation of high voltage hose and power quality inspection requirements. Therefore, it is necessary to control the adhesive force between the layers of the rubber hose is not lower than the technical standards, and the production of rubber hose parts with high viscosity hose is selected.

4. The appearance of the rubber water hose assembly quality can not be ignored. It not only affects the appearance quality of the rubber hose assembly, but also affects its use quality. If there are bubbles, pores or mechanical damage in the rubber, the skeleton layer and the skeleton layer will form corrosion, thereby reducing the contraction strength of the rubber hose, directly affecting the service life of the rubber hose components, and may even occur in use. Therefore, attention should be paid to the appearance and quality of the hose to eliminate the appearance defects that affect the quality inspection of the rubber water hose assembly.
