Q:How to detect the reliability of rubber hose

Bending test: after bending the hose to a certain extent, measure the minimum outside diameter of the bending part and the ratio of the outside diameter before bending, the passing capacity of the steel ball and the bending force when the tube is pressurized.

Q:What is a rubber core pulling method?

Hose core pulling for broken line and curve type pore channels, in addition to leaving the grouting hole and exhaust hole should also set the urinary bleeding hole, hole curve (line) to stay in the top hole, with the method of grouting hole.

Q:What is the maximum pressure that a hose can bear?

This hose with material, wall thickness, diameter is Dudu, but there are special hose pressure testing machine test the size of the market, you take a look at the next.

Q:The rubber is sheathed on the metal cylinder. How can it be connected?

With the combination of metal rubber is coated with adhesive before production and rubber vulcanization shaping, you can use this temporary experiment 502 geliahao for glue or adhesive, but the disadvantages of this thing with winter is not strong, the metal surface must be clean

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:Flex rubber joint installation skills, what are the materials of rubber soft joint?

Flexible rubber joint is normal for medium temperature of 0-60 DEG C usually water medium such as oil, acid, high temperature and other corrosive and texture should be selected under the peace situation should be relatively Tenai data can not be blindly on rubber joint or universal.

Q:What is negative pressure rubber shock proof joint? Is vacuum piping available?

With high pressure, good elasticity, large displacement, balance pipe deviation, absorbing vibration and noise reduction effect, convenient installation, but also can greatly reduce the noise and vibration of the pipeline system, which can solve all kinds of line interface displacement fundamentally, axial expansion and concentricity problems, mainly installed in the pump inlet the vacuum pump inlet, or large, can solve the 100% rubber joint suction flat phenomenon.

Q:How long is the service life of the gas hose?

The gas hose is connected to the gas pipeline and special gas hose with / out, according to the number of gas accident statistics analysis, because the gas hose aging or bitten by rats caused by gas leakage accident / Xi accounted for more than 30% of all gas accident.

Q:Will the electric water heater be well connected with metal hose or 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:How to identify the quality of rubber pipes for sewage treatment?

The general hose inside and outside the adhesive layer material with natural rubber, styrene butadiene rubber or butadiene rubber; hose with chloroprene rubber, nitrile rubber; acid and alkali resistant, high temperature resistant hose with ethylene propylene rubber, fluorine rubber or silicone rubber etc.. Structure: hose structure is usually divided into inner layer, outer layer and skeleton layer (or middle layer). The inner layer directly bears the abrasion and erosion of the conveying medium; the outer rubber layer protects the inner part of the hose from the damage and erosion of the external environment; the stock price is the pressure bearing layer of the rubber tube, and gives the strength and rigidity of the tube body. The working pressure of the hose depends on the material and structure of the skeleton.
