Q:Why should the high pressure hydraulic tube peel off the outer skin?
High pressure hose is generally relatively thick, there are steel wire layer, the purpose of peeling is to connect the tooth and steel layer close combination, the joint is more solid. But not all high-pressure hose needs peeling. Now many large companies do not need peeling. For example, pike.
Q:Why can the air conditioning connection be made of copper tube? How about rubber tube and aluminium pipe? Please heroes pointing for the dishes.
The pressure of the aluminum pipe is relatively small. "Again, when the aluminum pipe is too soft, it is easy to be flattened.".. Rubber tubes will decay if they are used! Withstand pressure is also high!
Q:What is negative pressure rubber shock proof joint? Is vacuum piping available?
Negative pressure resistant rubber shock joint is simple product requirements than the general negative pressure resistant rubber joint rubber joint is much higher, simply can't stand the pressure, for example the pipe diameter is 0.1kg pressure, rubber tube will suck flat, so with the outward pressure pipeline is completely different, negative pressure, diameter must be increase the pressure guide tube, negative pressure diversion tube also is what we usually say is a carbon steel pipe in the shock absorber rubber hose diameter, but joint diameter than the original diameter, the pressure guide tube, shock absorber rubber hose will not be sucked flat, so that the original vibration isolation and shock proof box the expansion effect is not affected, only the affected joint is slightly smaller diameter.
Q:What are the types of hose connectors?
You go to the material market to have a look, it depends on what kind of pipe you need, which is the oil circuit. Gas road or water pipe?. Different pipe joint names are not the same (not the same).
Q:Can the high-pressure rubber hose be followed by water pipes? Will it be poisonous?
No, because I did not meet the drinking water level requirement!! Hose with drinking water hose!! Drinking for a long time is poisonous!
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 communicating devices can be explained by liquid pressure. If the same liquid is contained in a U glass tube, a small liquid AB is conceived at the center of the bottom of the communicating device. If the liquid is stationary, it does not flow. The pressure of the liquid in the left tube toward the right side of the liquid AB must be equal to the pressure of the liquid in the right tube toward the left of the liquid AB. Because in the communicating vessel is filled with a liquid, the same two liquid column density, according to the formula of P= P GH liquid pressure that only when both sides is equal to the height of liquid column, the liquid column is equal to the pressure on both sides of the liquid film AB. Therefore, in the case of no flow of liquid, the liquid level in each vessel of the communicating device shall be kept flat. (ideal model method) the connecting device is characterized in that the liquid level in each container is flat only when the same liquid is contained in the container. If the container is tilted, the liquid in each container is about to begin to flow. One end of the liquid column flows to the lower end of the liquid column and stops flowing until the liquid level in each container is normal. As with rubber tube two glass tubes connected together in container with a liquid, which will be a fixed tube, the other tube up and down or tilt, can see the two tube level in stationary phase remained flat. The connecting device is provided with the same liquid, but the pressure on the liquid surface is unequal, and the pressure difference of the liquid surface is equal to the pressure difference produced by the liquid level difference of the two container of the communicating device.
Q:How can we prevent the aging of rubber tubes?
The second is the design of the structure of the rubber products (especially damping products), has a great relationship between aging and fatigue, should avoid stress concentration! If the product is good has been produced to prevent aging, more trouble! Can be sprayed on the rubber surface, spraying insulation polymer.
Q:What advantages does the Parker hose have in comparison with other hydraulic hoses?
Parker hose and other hydraulic hose advantages compared to:First: from the price point of view, the price of PAKER is the most expensive industry. High popularity.Second: if from the quality point of view, the quality of stability, high degree of recognition.Third: from the point of view of use, the difference is not obvious. PAKER things match well.Fourth: strong pressure resistance, rated 400bar hose, blasting pressure can reach close to 1000ba
Q:Does rubber hose drink from tap water? Is it poisonous?
.PVC is actually a vinyl polymerization substance, whose material is a non crystalline material. PVC materials often use stabilizers, lubricants, auxiliary processing agents, pigments, anti shock agents and other additives in practical use. Is not flammable, high strength, excellent resistance to climate variability and geometric stability. PVC has strong resistance to oxidizing agents, reducing agents and strong acids. However, it can be corroded by concentrated oxidizing acids such as concentrated sulfuric acid and concentrated nitric acid, and it is also not suitable for contact with aromatic hydrocarbons and chlorinated hydrocarbons. In addition, the terms person, vs, computer, abbreviated as PVC, and the PVC humanoid are often referred to as PVC.
Q:What's the metal hose for fire fighting?
Corrosion resistance, high temperature resistance, low temperature resistance (-196, ~+420), light weight, small size, good flexibility. Widely used in aviation, aerospace, petroleum, chemical, metallurgy, power, paper making, timber, textiles, construction, medicine, food, tobacco, transportation and other industries.1 、 flexible metal hose between flexible hose, bending radius is small.2 、 metal hose has better flexibility, no obstruction or stiffness.3 、 metal hose unit light weight, caliber consistency is good.4 、 flexible metal hose, repeated bending and flexibility.
