How to distinguish the advantages and disadvantages of the hose crimping machine:
- Check: Observe whether the hydraulic fittings and electrical components selected by the hydraulic hose crimperare brand-name products or regular manufacturers; whether the circuit configuration is normal; whether the pipeline design of the gas station is reasonable; whether the connection is leaking. If you pass the visual inspection above, you can proceed to the next inspection.
- Listen: Turn on the power of the device after booting, and listen to whether the device is operating normally of the crimping tool. If there is abnormal noise, it is usually because the coaxiality of the motor and the oil pump does not meet the standard. Another reason may be due to the unreasonable selection of oil pump displacement and pipe diameter. The result is not very good.
- Measurement: Finally, measurement the main parameters of the hydraulic pipe press machine
3.1 Put the crimping tool in dry running state and touch each mold base with your hands. There should be no shaking in the hands, otherwise it will be regarded as a substandard product.
3.2 Install the crimping tool on the mold, detain the sample joint, and measure the detained joint with a caliper or micrometer. The roundness and taper should be within 0.1mm, which is considered good.
3.3 The hardness of the mold base and the mold hardness are also the key to the normal use of the equipment in the future. Customers can ask the manufacturer to use a desktop or portable hardness tester to test the mold base or mold. When the base hardness of the mold is lower than Rockwell HRC60, it will affect the crimping quality of the hose.
3.4 Finally, check the uniform division of the eight petals of the mold base of the crimping machine and the flatness of the mold. Good equipment will specifically control and adjust these two items, while some inferior equipment cannot control the above two parameters.
