A booster pump is a pump used to increase pressure. Mainly in life is also very common, such as: water heater pressurization, bath pressure, the building when the highest hydraulic pressure booster and so on. There are many types of booster pumps, such as: pipeline booster pump, pneumatic booster pump, gas-liquid booster pump and so on. We will introduce the following booster pump principle. Booster pump principle: First booster pump filled with liquid, and then start the centrifugal pump, the impeller rapid rotation, impeller blades drive the liquid rotation, the liquid rotates by inertia to the outer edge of the impeller flow, while the impeller sucked liquid from the suction chamber , In this process, the liquid in the impeller flows around the flow vane, and the liquid acts on the vane in the flow around the flow. In turn, the vane acts on the liquid with an equal and opposite force to the lift, Do work, so that the liquid energy and out of the impeller, then the kinetic energy and pressure of liquid are increased. The gas-liquid booster pump operates on a similar principle to a pressure booster, exerting a very low pressure on the large-diameter air-driven piston, creating a high pressure when this pressure acts on a small area piston. Through a two-way five-way control valve, booster pump to achieve continuous operation. The one-way valve controlled by the high-pressure plunger constantly liquid discharge, booster pump outlet pressure and air-driven pressure. When the pressure between the drive section and the output liquid section reaches equilibrium, the booster pump stops operating and consumes no more air. When the output pressure drops or the air-driven pressure increases, the booster pump will automatically start running until it reaches the pressure balance again after the automatic stop. The use of single gas-controlled unbalanced gas distribution valve to achieve automatic reciprocating pump, gas drive part of the pump body made of aluminum. Wetted part of the media according to different choice of carbon steel or stainless steel. General pump has intake, exhaust two ports, the inlet can produce less than atmospheric pressure (ie atmospheric pressure) called "negative pressure"; in the exhaust port can produce higher than atmospheric pressure called "positive Pressure "; for example, often say that the vacuum pump is negative pressure pump, booster pump is positive pressure pump. Positive pressure pump and negative pressure pump are very different. For example, the gas flow, the negative pressure pump is the external gas is sucked into the suction nozzle; positive pressure is discharged from the exhaust nozzle; such as the level of pressure. According to the above description of booster pump principle, it is found that when the pipeline flow is less than or greater than the pump flow, the supercharging effect is not significant. Therefore, we should pay attention to is to check the reasons for the low pressure before buying, do not blindly buy. To buy, be sure to choose the right model.
PP wrap tape / PP proven tape Polypropylene anticorrosion Fiber tape ,reinforced tape to protect metallic and concrete surfaces against corrosive forces. It is by modified bitumen with synthetic rubber of increased thickness, laminated onto a film of woven Polypropylene fabric , which creates a strong bond with a pipe surface, protecting against moisture penetration and metal structures.This tape is the best solution for coating of pipes and repair.
