Theoretical requirements: not from the head, does not destroy the inner rubber hose
In order not to take off the head - withhold efforts should be large, in order not to damage the inner plastic - withhold the intensity should be smaller. To resolve this conflict without crimping hose cuttingmachine first election taper (0 taper) pressure pipe hydraulicmachines to make both ends of the front and rear hydraulic metal joints consistent data to avoid errors. (Note: If the front end of the compression strength of the metal connector is too large, will be crushed if the metal connector fitting backend compression intensity is too large, the inner rubber hose will fracturing, leading to hose leak, etc.).
How to withhold a satisfactory hose
When the user when the withholding of the high-pressure pipe, if the withholding amount is too small, then the weight between the connector and the hose is too loose, the role of the hydraulic hose withhold there may emerge from the joints in the initial period, if you withhold too large, then fittings and hose too tight, easily lead to the inner hose by local damage, cracks, hydraulic oil directly into the wire layer from the rupture, and then he went to the wire along the gap between the exudation coat tails, or has been channeling along the wire layer to build up somewhere, so that the outer layer of plastic produced drum kits or even rupture.
When the withholding can not withhold too fast, so likely to cause damage plastic and wire layer break, so the hose in use prematurely. In practice, when replacing the high-pressure hose, hose length chosen, wire layers, joint shape and size must be reasonable, and should minimize the degree of bending the hose, the majority of the damage is due to high pressure hose making improper .
