How to distinguish between a good and bad tube shrinking machine?

1. Look: It is to visually observe whether the hydraulic fittings and electrical components selected by the tube shrinking machine are products or produced by regular manufacturers;
Whether it is regular, whether the design of the pipeline of the oil station is reasonable, and whether there is oil leakage at the connection. If the above passes the visual inspection, the next step can be carried out.
2 Listen: Turn on the device after it is powered on, and listen to whether the sound of the device is normal. If there is abnormal noise, it is often because the motor and oil pump are installed in the same way
The shaft degree is not up to standard, and another possibility is caused by the unreasonable selection of oil pump displacement and pipe diameter, and then it is due to the selection of the motor or
The quality of the oil pump is not very good.
3. Measurement: After measuring the main parameters of the equipment
3.1 Let the equipment be in a state of dry operation, touch each module block with your hands, and there should be no shaking in the feel, otherwise it will be regarded as an unqualified product.
3.2 Install the equipment on the mold, crimp a sample joint, measure the crimping joint with a caliper or micrometer, and the roundness and taper should be buckled
Within 0.1mm, it is considered excellent.
3.3 The hardness of the mold base and the hardness of the mold are also the key to the normal use of the equipment in the future. Customers can request a benchtop or portable hardness tester from the manufacturer
Inspect the mold base or mold. When the hardness of the mold base is lower than that of Rockwell HRC60 and the hardness of the mold is lower than that of Rockwell HRC50, the crimping quality of the hose will be affected
Measure.
3.4 After that, check the eight-petal average indexing of the equipment mold base and the flushness of the mold. A good device will make special control adjustments for these two items, and some qualitative
Inferior equipment does not control the above two parameters.
