Q:How to detect the reliability of rubber hose

Hose size measurement: the inner and outer diameter, outer diameter, wall thickness, enhancement layer concentricity, inner and outer layer of glue thickness, assembly diameter, new GB and ISO increased the length and the measuring point mark, provides no pipe joint and a hose length of various pipe joint measurement method.

Q:What's the smell of petrol in the car and the trunk?! Especially after a long drive!

Have changed the gasoline pump, or because of the failure to disassemble the steam pump owners, if the car appeared gasoline, do not panic, this is because after the disassembly and assembly, the residue is not cleaned up. In fact, this situation is usually not met, the gasoline pump replacement cycle is 100 thousand kilometers. But now the gasoline filter is also installed in the tank, connected with the gasoline pump, and its replacement cycle is shorter, 40 thousand km, when the replacement of gasoline pump disassembly. In this case, just look at the gasoline pump installed is not correct, in cleaning the perimeter can be.

Q:Is the rubber pipe joint installed in the middle of the pipe and pump to absorb the shock?

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:Why should liquefied petroleum gas use strong rubber hose and liner?

Commonly called liquefied petroleum gasMain ingredients: ethylene, ethane, propane, propylene, butane, butene, etc. (oil resistance will accelerate swelling and aging).Appearance and properties: colorless gas or yellow brown oily liquid, has a special odor.In order to remind people of the leakage of liquefied petroleum gas in a timely manner, the processing plant often mixes a small amount of foul odor mercaptan or thioether compounds into liquefied petroleum gas, which is the source of special odor.These gases on the rubber has a certain corrosion, swelling (not resistant to oil will speed up swelling), aging effect, liquefied petroleum, so choose rubber seal to consider oil resistance, corrosion resistance, swelling!

Q:Which is better for binding files with rubber tubes and cotton threads?

In fact, the most suitable binding file is the file department I twine, such units are preserved, just to have you asked, hope to adopt

Q:The rubber is sheathed on a metal cylinder. How should they be connected?

If you describe it, it is recommended that a soft binder such as 704 silicone gel will be used to prevent shock absorption and separation. Metal surface to rust treatment, clean can be coated adhesive, rubber cover surface is best polished, degreasing treatment effect is good!

Q:Toilet hose and water tank joints leaking, how to repair?

No rib sleeve, the use of pipe outside the buckle fixed, sealed, may be the aging of the tube, buckle clamping difficulties and other reasons. If the pipe is aging, you can cut or replace the tube in the aging part. It is difficult to buckle and clamp, so you need to change the buckle.

Q:The gas water heater uses metal pipes and rubber pipes

Metal pipes are good. Rubber tubes are easy to fall off

Q:What glue can glue rubber tube?

1: clean: high temperature, quick drying glue, use dry cotton cloth or sand paper, then dust, oil, rust, etc., and then use the treatment agent or cleaning agent to clean, then clean the surface.2, sizing: flexibility speedglue unscrew the front cover, can be used as a glue bottle with cotton cloth to wipe clean and quick drying glue, can be set using needles or PE dropper, to control the flow of glue, ensure the bonding effect.

Q:The principle of the common bicycle valve

The diode is powered by single items. The bicycle valve is single - ventilated. Basically, a rubber is wrapped over the valve coreThe rubber is wrapped in the long, thin hole under it
