Q:How can the rubber tube be used properly and how to use it properly?
The hose burst caused by frequent and severe pressure impact. This situation is not generally under the static pressure caused by too much, but the number and intensity and pressure impact. Engineering machinery in operation, will be repeated in the hydraulic tubing suddenly increased or decreased, which impact on the oil pressure of frequent the damage of the oil seal, resulting in increased, loosening hose leakage and rupture foaming and pipe joint. Therefore, in operation, the valve stem can not be too hard, must be gentle.
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:Method for inserting glass tube into rubber tube when assembling instrument
If the outer diameter of the two glass tube to be connected is greatly different, the method can be used repeatedly to connect the glass tube into a channel or to be connected by a socket inserting method.In addition to the use of rubber sheathed outside the glass tube, can also be used for plastic pipe glass tube is sheathed, however, due to the elastic rubber pipe plastic pipe as well, so for sheathing plastic pipe with small diameter should be equal to the outer diameter of the glass tube.In addition, the use of plastic pipe sleeve glass tube should be adopted heat law, that is, the plastic pipe heating expansion and glass tube connection, and should not be rigidly inserted.Finally, because of the poor elasticity of the plastic tube, it is easy to age, harden and brittle, so when the glass pipe is connected with the plastic sleeve, the sealing measures must be adopted for the sleeve joint, and the sealing is usually done by gluing or waxing.
Q:How to remove hose odor?
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:Must the hose for the cooker be made of oil resistant rubber hoses?
When the gas combustion equipment and gas pipeline for hose connection, the design should meet the following requirements: (1) the burner of household gas stove and laboratory use, the connecting hose length should not exceed 2m, have no interface; (2) industrial production with mobile gas burning equipment, the connecting hose the length should not exceed 30m, the interface should not exceed 2;...
Q:What are the categories of hose?
According to the use of performance: ordinary hose (cloth water hose, air hose, braided hose, air hose braided fiber, fiber winding hose, fiber winding air hose (hose); medium resistance oil resistance, acid and alkali resistant hose, steam hose etc.); special hose (hydraulic hose, brake hose drilling mud, hose, spray hose, hose extrusion etc.) Hengshui Yajie rubber.
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:Is the rubber pipe joint installed in the middle of the pipe and pump to absorb the shock?
Control the noise produced by parts of machinery, equipment, and equipment. The pump foundation of the new pump house should adopt heavy weight to prevent vibration from producing noise. Vibration isolation should be set up with rubber vibration isolating pads to reduce vibration noise. Each pump unit shall be provided with a foundation to prevent resonance. Use "soft" connection as far as possible in the suction pipe and pressure pipe of the pump. Periodic maintenance problems, such as packing leakage, equipment parts loose, serious wear and tear of equipment parts, mechanical vibration and so on, should be repaired in time, thereby reducing noise.
Q:Carbon dioxide gas shielded welding torch wire feed hose joint, that steel wire can not be drawn out, how to solve it, with welding?
Some of the torch wire feeding hose can not be replaced, it is fixed dead, such as Xiong Gu, Lincoln's self shielded flux cored wire, welding torch.
Q:Which is safer for stainless steel bellows and rubber tubes for gas pipelines?
Stainless steel bellows, installation is simple and quick. Because the elasticity of the stainless steel bellows is good, only two special tools can be bent in hand during the operation, and no joints can be arranged in the wall or the decorative layer when buried, which reduces the risk of leakage.
