Q:Why can the air conditioning connection be made of copper tube? How about rubber tube and aluminium pipe? Please heroes pointing for the dishes.
In fact, aluminum can, such as the refrigerator evaporator is aluminum, not only with the hose, the hardness is not enough in fact even the refrigerator either with brass or aluminum, for a long time or leakage, so you can not use the hose. The aluminum tube in the fridge is the easiest place to leak
Q:What is the method of making large diameter rubber joint?
There are three ways to apply large diameter flanges:First, raw material steel plate, through the template blanking: 1/4, 1/6, 1/6, and then welding lathe processing, drilling.Second, hot rolled flange blank, then lathe, drilling.Third, cold roll flange blank, steel plate into strips, cold roll machine, roll round, lathe, drilling machine processing.
Q:Three yuan ethylene propylene rubber tube covered with nylon PA66, what glue can not afford the layer?
Rubber and nylon 66 composite needs special treatment, high temperature vulcanization will not rise layer, we can wait for production, need to produce details, Baidu search: rubber technology, Li Yuan studio.
Q:Laboratory condensate water pipe must use rubber tube, shall not use latex tube reasons
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.
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:How can you pump out the water from a fishpond with a rubber tube?
Hold both ends of the rubber hose with both hands. One hand blocked nozzle, not to leak. Inhale with the mouth, suck the air out of the rubber tube, and then quickly put the blocked end into the tank. The lower end of the mouth is lowered and the water will flow out automatically. If there is no outflow, then put the rubber tube directly in the fish tank and inhale at the other end with the mouth. The water will be guided out, but the action should be quick, otherwise the water will remain in your mouth. In fact, this method is also from the oil tank in the car oil discharge method.
Q:Method for connecting glass tube and rubber tube
Just one end of the glass, wet with water, and then rotate hard
Q:What are the production processes and characteristics of high pressure rubber hose?
Production flow chart of high pressure steel wire braided hose:High voltage wire winding production process: rubber hose, pipe extrusion, boiled casing (core wipe silicone oil), wrapped around the screen (screen on the casing after finishing cutting winding), a layer of glue, the first layer of steel wire winding, two winding layer of glue, second layers of wire, third in the layer of glue, third layers of wire winding layer, fourth layer, fourth layer winding wire, package cover, water roll of cloth, cloth, water solution of vulcanization, mandrel stripping, a hydraulic, appearance and dimension inspection and packaging storage.
Q:Standard for implementation of type KXT-1 rubber joints
It is divided into 3 kinds: flange type, fixed flange type and thread type by connection. The structure can be divided into 5 kinds: single sphere, double sphere, different diameter body, bent sphere and wind pressure coil. A tubular rubber component is composed of inner and outer layers of rubber, cord and steel ring, which is vulcanized and molded and then combined with a metal flange or a parallel joint.
Q:Between the two flanges in the middle of the rubber pipe, what is the name of the connection?
Rubber flexible joint is also called rubber flexible joint, flexible rubber joint, flexible rubber joint, rubber shock absorber and so on.
