A booster pump, as the name implies, is used for pressurizing pump, its main uses are water heater pressurization, high building low water pressure, sauna, bath, and other pressurization, the pressure of the upper layer of the apartment with insufficient water pressure, solar automatic pressurization, reverse osmosis water purifier pressurization and so on.
Booster pump classification
Biogas type
A pneumatic booster pump is divided into a gas-liquid booster pump and a gas booster pump. The principle of booster pumps is to use the low pressure of large-area pistons to produce the high hydraulic pressure of small-area pistons. In the industrial field, it is used for clamping machine tool chucks, charging accumulators, charging high-pressure bottles, reducing pressure gas into high-pressure gas, and so on. Whenever the air source pressure is not high enough, whether it is a mechanical or test device, booster pumps can be used.
Gas drove, no arc and spark, completely used in flammable, explosive liquid or gas place. No matter what causes the pressure drop in the pressure retaining circuit, the booster pump will automatically start to supplement the leakage pressure and keep the circuit pressure constant. Compressed air, nitrogen, water vapor, natural gas, and so on can be used as the driving gas source of the pump.
Gas-liquid type
Until the pressure balance is reached again, it will automatically stop using a single gas-controlled non-equilibrium gas distribution valve to realize the automatic reciprocating movement of the pump. The gas driven part of the pump body is made of aluminum alloy. The liquid part selects carbon steel or stainless steel according to the different mediums, and the full set of seals of the pump are imported high-quality products, to ensure the performance of the gas-liquid booster pump.
Air type
The principle of the air booster pump is to use the low pressure of the large-area piston to produce the high hydraulic pressure of the small-area piston. The air booster pump is used in the working environment where the original air pressure system needs to increase the pressure. It can increase the air pressure of the working system by 2-5 times. It only needs to use the compressed air in the working system as the air source. The pump is suitable for single air source pressurization. No power supply (can be used in the field of explosion protection). Within the pressure range of the pump, adjust the regulating valve to adjust the intake pressure, and the output hydraulic pressure can be adjusted accordingly.
Chlorine gas type
The working pressure range of the chlorine gas booster pump is large. Different types of pumps can obtain different pressure areas, and the input and output pressure can be adjusted accordingly. Can reach extremely high pressure, gas 90Mpa. Wide range of flow, for all models of pump only 0.1Kg air pressure can work smoothly, at this time to obtain the minimum flow, adjust the air intake can get a different flow. Easy to control, from simple manual control to complete automatic control can meet the requirements. Automatic restart, no matter what causes the pressure drop of the pressure retaining circuit, will automatically restart, replenish the leakage pressure, and keep the circuit pressure constant. Safe operation, gas driven, no arc and spark, can be used in dangerous situations.
Working principle
Fill the gas booster with liquid first, then start the centrifugal pump, the impeller rotates rapidly, the impeller blades drive the liquid, and the liquid flows to the outer edge of the impeller by the rotational inertia and sucks the liquid from the suction cavity impeller at the same time. In the middle flow, a lift force is generated on the blades in the flow around the liquid, and the blades act on the liquid with a force equal and opposite to the lift force. This force acts on the liquid, so that the liquid gains energy and flows out of the impeller. At this time, the kinetic energy and pressure energy of the liquid increase.
A gas-liquid booster pump works like a booster, applying very low pressure to a large diameter pneumatic piston. When this pressure acts on a small area piston, high pressure is created. Through a two-five ventilation control valve, the booster pump can be operated continuously. The high-pressure plunger controlled by the check valve continuously discharges the liquid, and the outlet pressure of the booster pump is related to the pneumatic pressure. When the pressure between the drive part and the output liquid part reaches equilibrium, the booster pump will stop running and no longer consume air. When the output pressure drops or the air drive pressure rises, the booster pump will automatically start and run until the pressure balance is reached again and automatically stops. The automatic reciprocating motion of the pump is realized by a single air-controlled unbalanced air distribution valve, and the air drive part of the pump body is made of aluminum alloy. Liquid parts are made of carbon steel or stainless steel according to different media. Generally, the pump has two intake ports and an exhaust port. The pressure that can generate a pressure lower than atmospheric pressure (ie atmospheric pressure) at the intake port is called "negative pressure"; the pressure that can generate a pressure higher than atmospheric pressure at the exhaust port is called "positive pressure". For example, the vacuum pump is often said to be a negative pressure pump, and the booster pump is a positive pressure pump. Positive pressure pumps and negative pressure pumps are very different.
