Q:How to detect the reliability of rubber hose

Hydraulic test verification pressure test: Test hose and assembly under verification pressure, continue 30s-60s, whether to produce leakage, deformation and damage. Compression deformation test: keep 1 minutes under the specified pressure (work pressure, verification pressure or other pressure below the proof pressure), measure the length and diameter of the hose, twist angle and bend. Bursting pressure test: Determination of the pressure at which the hose burst during the specified step-up rate. Leak test: save 5min at 70% of the minimum blast pressure, and check again and again for leaks or damage. Due to the fact that water is often used in tests, the pressure and leakage pressure at normal temperatures may be slightly lower at normal temperatures.

Q:Method for connecting glass tube and rubber tube

Wet the connection with water first. Just turn it clockwise

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?

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.

Q:How far is the gas cooker from the gas riser in the kitchen?

Rubber pipes shall not be worn through the chamber and should be checked regularly. It is found that aging and damage should be replaced in a timely manner (rubber tubes shall be used for a period of not more than 18 months).

Q:HDPE double wall corrugated pipe joint shall be made of elastic sealing rubber ring and socket joint interface. What are the requirements for rubber ring joint?

The interface method should be carried out according to the following procedures: DN400 pipeline and below, by a man with a cotton rope hook is installed pipe socket, the other one with a long lever oblique insertion based cross baffle against the tube end of the center position, and then forced the tube slowly into after the installation of HDPE double wall corrugated pipe the pipe socket to a predetermined position; more than two sets of DN400 pipeline by hand hoist will pull in pipe section. When the interface is closed, the spanner on both sides of the pipe section shall be pulled synchronously, so that the rubber sealing ring is properly positioned and is not distorted or not falling off.

Q:The rubber tube of the gas cooker is aging. It's leaking. Can you change it for yourself?

You see what your gas range is, it is best to go with a metal hose, the province later by the mouse bite. My father is quite understand, our family's Hengtong metal hose was changed just the year before last, it's really much better

Q:How do the automobile rubber hoses combine with the quick couplings?

The fluorine fast joint is aligned with the charging head on the air conditioner of the automobile, and can be connected by pressing lightly. Then the screw handle on the fast joint can be tightened reversely, so that it can be filled.

Q:M40 and M50, and then the hose is 2 "what does the box connection mean?"

One with teeth and one with hose, the hose is 2 inches, 2 inches of hose, and the inner hole is 50MM (1 inches =25.4MM).

Q:How can I connect the gas tank connection hose?

The general is directly inserted into the connector on the line, if loose, can use wire twist, still feel not reliable, can go to the market to buy two hoop, screw on the line.Keep it clean.
