Q:Is the rubber pipe joint installed in the middle of the pipe and pump for shock absorption?
A pump is a machine that transports liquids or pumps liquids. It will be the prime mover of the mechanical energy or other external energy transfer to the liquid, the liquid energy increase, mainly used to transport liquids including water, oil, alkali liquid, emulsion, suspension emulsion and liquid metal, but also transport liquid, gas mixtures and liquids containing suspended solids. Pump performance of technical parameters are flow, suction, lift, shaft power, water power, efficiency, etc.; according to the different principles of work can be divided into volume pumps, vane pumps and other types. Displacement pump is to use its studio volume changes to transfer energy; vane pump is to use the rotating blade and water interaction to transfer energy, there are centrifugal pumps, axial flow pumps and mixed flow pumps and other types.
Q:What is a hose valve?
The rubber tube is made of imported rubber and is made by special chemical formula. The utility model has the advantages of wear resistance, corrosion resistance, frost resistance, full sealing, no leakage, etc.;It is superior to gate valve, globe valve, regulating valve and stainless steel valve;It is convenient to overhaul, simply disassemble the valve body and replace the rubber tube. The valve body and the headstock can be used permanently. The cost is extremely low, and the service life can be raised by more than 3-5 times.Medium in the hose running, no flow resistance, do not touch the opening and closing mechanism and valve body, so as not to block the running parts, the operation is particularly flexible, greatly easing labor intensity.
Q:The principle of the common bicycle valve
An elastic thin edge hose is placed below to form the whole of the core. In fact, it is a one-way valve. When inflating the bicycle tyre, the compressed air in the air pump enters the valve core from the hollow part, and the elastic rubber tube is top, and the air enters the tyre.
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:The pipe of the gas water heater is buried in the wall. It is made of nylon tube and rubber tube. Is it possible to use rubber tube?
Rubber tubing only. This is because rubber and other organic substances will age, and then easily burst. It's the same in the wall, but it's only a little longer. The consequences of the rupture are unimaginable: gas leaks, gas poisoning, fire explosions, and so on. However, there is a layer of nylon tube protection, rubber tube should be able to use the next renovation of the era without damage, and then added to the upper wall, the effect should be more ideal.
Q:How can the hose of natural gas be connected to the water heater?
One end is connected to the water heater, the other end is connected to the gas pipe, and the other end of the gas pipe needs to be equipped with three through. Are you installing it yourself? Why don't you find the man who installed the water heater to put you through? Suggest that you still find professionals to connect, so that relatively safe. Hope to be of help to you.
Q:Automotive applications of rubber hose
Each kind of rubber has its characteristic, therefore is specially important in the hose material selection. Basically the high-end cars use materials is relatively good, some poor materials using mini car, van, car and as some in the use of nitrile rubber as fuel tube, nitrile rubber are not suitable for fuel system. Thus, the substitution of epichlorohydrin rubber fluorine rubber hose is relatively extensive.
Q:Why does Br2 corrode rubber tubes?
Br2 bromine gasBr2 bromine element at room temperature is dark brown liquid, soluble in water, 100g water can dissolve about 3G bromine. Highly volatile, toxic, steam strongly stimulate the eyes, mucous membranes and so on. The water solution is called bromine.
Q:What material is the rubber joint used in the desulfurization pipeline? What's the difference?
The desulfurization pipeline can be used with three yuan EPDM rubber ring joint, and PN4-6 is no problem.Generally, the desulfurization pipeline is weak acid base.
Q:Rubber tube in the production process need to wrap cloth, in order to finalize the design, I want to know what cloth is winding cloth, what is the specification, please god!
Rubber pipes need to be wrapped in fabric during production so that they can be easily formed. I want to know that the winding fabric is commonly called water cloth". Specifications can generally be winding as required!
