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 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:How do the automobile rubber hoses combine with the quick couplings?
Turn the rotary handle on the quick connector to the open position first;
Q:Hydraulic hose joint configuration
The utility model relates to an ultrahigh pressure drilling hose joint: an ultrahigh pressure drilling hose joint used on an oil field mining device, which comprises a sleeve and a connecting section which is connected with the core rod ring sleeve. The inner hole of the sleeve and the outer round surface of the core rod of the connecting section are correspondingly matched in turn, and the utility model is connected with an anti pulling out section, a sealing section and a transition section. Both the stripping section and the sealing section are respectively provided with a plurality of annular grooves on the excircle surface of the inner hole of the sleeve and the core rod, and are matched with or matched with the bulge. The test shows that when the working pressure of the inner cavity of the hose is 70MPa, the pulling resistance and the tightness of the hose joint can still be effectively guaranteed. The joint of the hose is welded because of the high temperature generated by the welding, and the locking of the sealing adhesive layer of the inner cavity of the rubber tube is effectively prevented from tearing by the locking of the transition section. Compared with the prior art, the production failure of the hose joint is eliminated, and the service cost is obviously reduced.
Q:What are the properties of stainless steel metal hose materials?
The stainless steel metal hose is made up of corrugated pipe, stainless steel braid net and two ends joint.
Q:How do I get the hose for the gas cooker?
Stainless steel bellows, stainless steel bellows, with a service life of ten years. The outside of the tube is covered with a layer of yellow plastic. All the inside are made of stainless steel. The ends of the pipe are connected with the mouth. There is also a black rubber piece, which is connected with the valve. After the tightening, the rubber sheet will expand and prevent the depression. Some live in a building or a cottage residents, plastic hose home is often a mouse or other insect bite, the use of stainless steel tube after it will not happen.
Q:Do I need a shim for the flat metal hose joint?
If the two connections are flat, they must be placed gaskets, usually with PTFE gasket.
Q:How long is the service life of a rubber tube?
This is really bad to determine, the environmental impact is very large, so it is difficult to judge
Q:How can the rubber pipe leaking from the cold water inlet of the electric water heater do?
Estimation is inside the pipe aging cracking due to Water Leakage, no maintenance necessary, unless it is a joint sealing ring in aging can replace the sealing ring of new or with rubber or other flexible items I cut a replacement.
Q:How often do the oil - resistant rubber pipes undergo atmospheric pressure testing?
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.
