Q:How much is a gas hose a metre? At least 1 meters, 5 safe?
General 10 or so can be, the length of 1 meters to 1.5 meters can be, too short, unsafe, it makes sense.
Q:What are the standard numbers for hose couplings? What standards are they used to accomplish?
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..
Q:The basement of submersible sewage pump outlet pipe installation need and flexible rubber joint is not installed? Can not?
Rubber joint, also called shock proof throat, is mainly used in the entrance and exit of pumps. It is used to absorb the noise caused by vibration during the operation of pumps.
Q:How long is the service life of the gas hose?
The protection work is very important, regular replacement of gas hose and make use of the gas hose gas pipeline safety in general, the gas hose has a life span of two years, usually pay more attention to inspection / check whether the aging hose, wear, corrosion or bad connection, avoid leakage.
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: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?
Siphon principle: that is the principle of connected devices, plus in a closed container, the pressure on the liquid, everywhere equal. The siphon is filled with water, there is no gas, the water level of the water inlet is high, and the water outlet is closed with palm or other objects. The pressure is equal everywhere. When all are arranged, the water outlet is opened, although the atmospheric pressure on both sides is equal, the water level at the water inlet end is high and the pressure is large, and the water inflow is continuously flowed out of the water outlet.
Q:In long-term high temperature environment, silica gel tube and three yuan ethylene propylene rubber hose which is good durability?
Others, such as three yuan ethylene propylene and nitrile rubber hose, are basically black. Long term use of plastics can cause fading and deformation. The chemical properties of silica gel are stable and the physiological inertia is good. They are very resistant to biological aging, have no rejection reaction with limbs, and have better anticoagulant properties.
Q:Rubber soft joint, what brand of good, the best price is more reasonable. Don't say anything expensive.
There are many kinds of rubber joint products produced in the West Village of Gongyi. The prices are high and low,Gongyi Kin Kun water supply equipment factory produces rubber soft joints all year round
Q:The newly purchased natural rubber tube is too large. How can it be removed?
When rubber is peculiar, it can be scrubbed by hydrogen peroxide. After drying, the odor will disappear. Or with waste tea sent to rubber products, tea has the role of adsorption odor.
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!
Widely used in rubber, special rubber, high pressure steel tube; the standard for mud suction hose, hose, hose winding wire; suitable for thick rubber rollers, rubber fender and some rubber expansion force; and the roller for thick water cloth curing wire reinforcement can not reach the the required hardness.
