Our soft and portable DIN EN853 2ST steelwire braided hydraulic hose which is in compliance with international standardDIN EN853 2ST, is widely applied to the applications where the workingtemperature ranges from -40℃to 100℃, such as engineering, hydraulic working as well aspetroleum based or water based hydraulic liquids delivering equipment
- Q:How can the soft joint of the pipe be elongated during use?
- Do not pay attention to the daily maintenance of pipeline flexible joint, because pipeline flexible joint is composed of a natural rubber and other synthetic rubber formula made in accordance with the proportion, because from the ultraviolet irradiation, the sun is long time exposure, the surface deformation or cracks, and maintenance method has two kinds, one is a surface covering a layer of sunscreen, no requirements of the network, as long as they can block the direct sunlight, the second method is talcum powder on the surface of the rubber joint, but also need to be covered with direct sunlight to place.
- Q:The difference between the rubber pipe and PE pipe?
- PE is one of the most basic plastics of polyethylene plastics. It has a good economy, and should have a series of advantages, such as stable and reliable interface, material impact resistance, anti cracking, aging resistance and corrosion resistance. Plastic bags, plastic wrap and so on are PE, HDPE is a high crystallinity, non-polar thermoplastic resin.
- Q:Do the rubber joint and Y filter need flange connection?
- Rubber hose joints are usually externally threaded, and type Y filters are internally threaded and are directly connected to the same caliber.Flange connection also has ah, according to demand
- Q:How can I remove all the flavor on the rubber hose?
- After the hot water is directly boiled, wrap it directly with transparent glue
- 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:What is the principle of communicating devices? What if the rubber tube is used as a connecting device to change the water for the fish?
- The principle of siphon principle has long been known by the Chinese people for the discovery and application of siphon principle. Hong Straw manufacturing principle application of siphon, in ancient China called "sub", "partial" and "siphon" or "siphon". At the end of the Eastern Han Dynasty, thirsty for irrigation appeared. In southwest minority with a long curved bamboo festival to drink, but also the application of the physical phenomenon of siphon. The song "Ceng Gongliang Wujing Zongyao", making the Straw useful bamboo rainbow mountains spring bring down the record barrier. China ancient also uses siphon principle is made. A fire extinguisher is a necessary war in the city. The Song Dynasty Su Shi "dongpozhilin" Volume 4, recorded by the Sichuan salt brine pump suction to the ground. The book contains: the bamboo tube, no bottom orifices on the leather hanging a few inches out of the water, gas, breathing and the opening and closing of a cylinder caused by water bucket number. "Using the method of pump water to irrigate seedlings induced in the Ming Dynasty also talked about the" tree "in the book, the ancient China siphon principle is also discussed. During the northern and Southern Dynasties, the book "Yin Zi nine drugs", said: "the bottle stored two orifices, the water to the reality of the" pour "; closed a water, the lid (gas) does not rise, then (water) does not drop. A well is full of water, but it does not drop
- Q:Difference between non-standard rubber joint and national standard rubber joint
- Rubber joint national Ministry of water conservancy is standard CJ/T208-2005 documents of rubber joint standard, this paper has clear rules for the product, identify the products should meet the following characteristics: standard rubber joint extrusion is produced by the rotation of the screw, the glue is advancing, and with the help of the mouth, but the needs of various semi-finished extrusion the shape of the. The extrusion process is characterized by uniform and compact quality and easy conversion of semi-finished product specifications and section shapes. The extrusion process of the national standard rubber joint in the extruder is divided into two parts: one is the extrusion system used for pushing the rubber; the two is the die system, which is used to form the rubber to make a definite section shape. Therefore, in the process of pressing, the rubber layer is usually more than ten layers, and the rubber joint has the characteristics of compact structure and high pressure resistance.Non-standard rubber joint is in the national standard between substandard products and national standard products, often illegal businesses use to reduce the rubber joint, the number of layers to reduce the cost of rubber joints. Use non-standard products instead of GB products. Non-standard products in use process, because the arc bearing layer, rubber layer is insufficient, the strength drops, in the use process is easy because the pressure withstanding insufficient causes the pipe network to burst.
- Q:Is the electric water heater well connected with the metal hose?
- For electric water heater, now the industry is required to use PPR pipe to its inlet and outlet for welding, on the one hand, long service life, can effectively prevent the water heater inlet and outlet leakage;
- Q:The function of rubber joint?
- The utility model has the advantages of small size, light weight, good elasticity, convenient installation and maintenance
- Q:What is the essential difference between natural rubber and three yuan ethylene propylene rubber?
- The electric property of natural rubber is a kind of non polar material, and it is a better insulating material. When the natural rubber vulcanization after the introduction of polarity factors, such as sulfur, accelerator, so that insulation performance.The dielectric properties of natural rubber are a nonpolar substance that is soluble in non-polar solvents and non-polar oils. Natural rubber is not resistant to cyclohexane, gasoline, benzene and other media, non vulcanized rubber can be dissolved in the above medium, vulcanized rubber swelling. Natural rubber insoluble in polar acetone, ethanol, more insoluble in water, resistant to 10% hydrofluoric acid, 20% hydrochloric acid, 30% sulfuric acid, 50% sodium hydroxide and so on.
