Or withhold machine, pressure machine identification!

Or withhold machine, pressure machine identification!

Identify withhold machine, pressing machine and the better we can take a look, listen, three measurement method to identify:

1, see: is through visual observation withhold machine, pressure machine selection of hydraulic components and electrical components are famous brand products or normal manufacturer of production; Circuit configuration is neat; Gas station piping design is reasonable; Connection with and without oil leakage phenomenon. Such as more than through the visual, can test the next step.

2, listen to: when the power is connected the equipment start, listen to the sound equipment operation is normal. If there are any abnormal noise, often because the motor and pump installation alignment is not up to standard, another may be because the pump displacement caused by unreasonable selecting and pipe diameter, then there is due to choose the quality of the motor and oil pump is not very good.

3, measurement: the last measure the main parameters of the equipments

3.1 let equipment in air line condition, touch each mold piece, feel there should be no dithering phenomenon, otherwise considered not qualified products.

3.2 put device on the mold, withhold a sample joint, the withholding of joint is measured with a caliper and micrometer, roundness and thread taper should be within 0.1 mm, is good.

3.3 after the mold base and mold hardness hardness is equipment can be the key to the normal use. Customers may require the manufacturer to use desktop or portable hardness tester to test the mold base or die. When the mold base is lower than the rockwell hardness HRC60 mold hardness is lower than the rockwell HRC50, will affect the quality of rubber hose withhold.

3.4 and at last the test equipment of the mold base eight disc divide and mould level degrees. Good equipment will have two special control adjustment, and some of the inferior quality of the equipment is out of the control parameters of the two.
