Our SoluForce Heavy HT has a design temperature of 105°C/ 225ºF and actual operating temperature of 85°C/ 185°F – a level of performance unmatched by any other Flexible Composite Pipe (or RTP) available today.HBS Portable Handheld Fiber Laser Marking Machine with safe cover HBuding laser cable and air fume extractor pipe. The dust produced by marking machine, can be sucked out from this tube, in this way, the environmental protection will be well done, and the dust will not affect operator's health. (2) Well-designed handle system for operator.A liquid’s boiling point corresponds to the temperature at which its vapour pressure is the same as the pressure of its environment. If water, for example, is subjected to a sufficient drop in pressure at room temperature, it will boil. Across any pumping system there is aplex pressure profile. This arises from many properties of the system: the throughput rate, head pressure, friction losses both inside the pump and across the system as a whole. In a centrifugal pump, for example, there is a large drop in prease again within its vanes (see diagram). In a positive displacement pump, the fluid’s pressure drops when it is drawn, essentially from rest, into the ceases again when it is expelled. If the pressure of the fluid at any point in the pump is lower than its vapour pressure, it will literally boil, forming vapour bubbles within the pump. The formation of bubbles leadeased vi... See full list on To avoid cavitation, the pressure of the fluid must be maintained above its vapour pressure at all points as it passes through the pump. Manufacturers specify a property referred to as the Net Positive Suction Head Requiredor NPSH-R – this is their minimum rmended fluid inlet pressure, expressed in metres. The documentation supplied with your pump may contain charts showing how NPSH-R varies with flow. In fact, NPSH-R is defined as the suction-side pressure at which cavitation reduces the discharge pressure by 3%. So, in designing the suction-side pipework for your system, you must ensure that it exceeds the manufacturer’s NPSH-R rating for the operating conditions. Your calculated value is termed the NPSH-Available (NPSH-A). Remember, a manufacturer’s NPSH-R rating is the minimum rmended inlet head pressure: a pump is already experiencing cavitation at this pressure. Consequently, it is important to build in a safety margin of 0.5 to 1m to take account of this and other fac... See full list on Pumps, and especially centrifugal pumps, work most efficiently when the fluid is delivered in a surge-free, smooth, laminar flow. Any form of turbeases wear and tear on the pump’s bearings, seals and otherponents. There should be at least 5 pipe diameters’ worth of straight piping connecting to the pump. Never connect an elbow, reducer, valve, or strainer within this final run of pipework. If you connect an elbow directly to the pump flange, the fluid is effectively centrifuged towards the outer curve of the elbow and not directed into the centre (the eye) of the impeller. This creates stress on the pump’s bearings and seals which often leads to wear and premature failure. Sometimes, it’s just not possible to make provision for a sufficient settling distance in the pipework before the pump. In these cases, use an inline flow conditioner or straightener. It’s standard practice to employ suction-side piping one or two sizes bigger than the pump in... See full list on It’s best to keep air or vapour out of the pipework. Entrained gases causease noise, vibration andponent wear and tear. It’s therefore important to position the feed pipe correctly in the tank or vessel. It should be fully submerged. If it’s too close to the surface of the fluid, the suction creates a vortex, drawing air (or other vapours) into the liquid and through the pumping system. The feed pipe should also be clear of any other pipes, agitators or stirrer-paddles – anything that might drive air into the fluid. In shallow tanks or ponds, it may be advisable to use a baffle arrangement to protect the feed pipe from air entrainment. See full list on You should also make sure that the feed pipe isn’t too close to the bottom of the tank or pond. If it is, the suction may draw up solids or sludge instead of air or vapour! The fluid may contain suspended solids in any case. Some displacement pumps can cope with a mixed phase supply without any damage or major loss in performance. Centrifugal pumps are not so robust and must be protected from solids. In this situation you’ll need to install a filter or strainer. Filters can create a large pressure drop and be responsible for cavitation and friction-loss. The filter screen should have at least three times the free area of the pipe cross-section. Use a differential pressure gauge across teased pressure drop before clogging problems arise. This will also help in the accurate assessment of NPSH-A. See full list on Obviously, pumps should be securely located - but so should the pipework. Don’t use one to support the other. All otherponents must be just as securely located and create no stresses or strains on any other parts of the system. Ensure that the pipe connecting to the pump’s inlet flange is aligned precisely with it. If you need to install non-return valves or flow control valves fit them on the discharge side of the pump, and never in suction-side pipework. See full list on Problems in suction side pipework often have damaging consequences for the system pump and can be avoided by following these guidelines: 1. Ensure that conditions do not favour cavitation, particularly if you are using a centrifugal pump. This requires careful selection of the pump, its positioning and the head pressure. 2. Position the feed pipe to minimize entrainment of air/vapour and solids. 3. Minimize friction and turbulence by choosing appropriate pipes andponents: 4. Use pipes with a diameter twice that of the pump’s suction side flange. 5. Ensure that the pipework is aligned with the pump’s flange and straight for at least 5 pipe diameters. 6. Use an eccentric reducer orientated to eliminate air pockets. 7. Keep the pipe velo below 2m/s. See full list on
