Q: What are the production processes and characteristics of high pressure rubber hose?: High pressure wire braided hose production process: rubber, rubber mixing, extrusion, heat pipe casing (core casing, silicone oil and then wipe) molding glue, woven wire (wire stranding), package glue, water reel cloth, cloth, water solution of vulcanization, mandrel stripping, cutting head, pressure test and inspection packaging and warehousing.

Q: Why should the high pressure hydraulic tube peel off the outer skin?: Skinning requirement:The stripping length of hydraulic hose shall be two to four mm shorter than the caseA layer without peeling, more than two layers stripped to see the steel wire, otherwise the shell is easy to fall offThe size of the joints to be installed depends on the size of the joint and the quality of the hose, just start recording more to find the most suitable size.

Q: How can the rubber joint be classified according to the range of temperature?: According to the applicable temperature range can be divided into general, mild, special three categories.

Q: The difference between the rubber pipe and PE pipe: The characteristics of the rubber tube has physiological inertia, UV resistance, ozone resistance, resistance to high temperature (-80 to 300), high transparency, strong resilience, resistant to compression permanent deformation, oil resistance, impact resistance, acid and alkali resistance, wear resistance, flame resistance, voltage, electric.

Q: Hose wire is it? What's the function?: It is used to make the skeleton material of high pressure hose, and increase the pressure resistance of the high-pressure hose.

Q: Difference between non-standard rubber joint and national standard rubber joint: GB and non standard. GB type rubber joint refers to the material selection and production in accordance with the relevant 02S404 or 02S312 standards of the Ministry of construction, and has strict requirements on flange thickness, flange thickness, diameter and thickness.

Q: What is the essential difference between natural rubber and three yuan ethylene propylene rubber?: The glass transition temperature of natural rubber is -72 Deg. C, plastic flow temperature is 130 degrees centigrade, start decomposition temperature is 200 degrees centigrade, intense decomposition temperature of 270 DEG C. When natural rubber is vulcanized, its Tg rises, and no more viscous flow occurs.

Q: Is the rubber pipe joint installed in the middle of the pipe and pump for shock absorption?: Control the noise produced by parts of machinery, equipment, and equipment. The pump foundation of the new pump house should adopt heavy weight to prevent vibration from producing noise. Vibration isolation should be set up with rubber vibration isolating pads to reduce vibration noise. Each pump unit shall be provided with a foundation to prevent resonance. Use "soft" connection as far as possible in the suction pipe and pressure pipe of the pump. Periodic maintenance problems, such as packing leakage, equipment parts loose, serious wear and tear of equipment parts, mechanical vibration and so on, should be repaired in time, thereby reducing noise.

Q: Why should the water stop strip be joined by heat instead of superposition?: Lap joint of rubber water stop belt is lap joint, this method is not allowed in engineering, glue glue and do not use overlay. In the case of splicing, it is equivalent to not doing any treatment at the joint. In the process of pouring, the sealing strip is prone to roll and twist.

Q: How to make sure the rubber hose will not be worn off?: This depends on experience, not carefully measured out of the value is also a great error
