Air booster usage precautions

I. Explanation of air booster

The air booster is, as its name suggests, a machine used to charge air, and is also known as an air booster pump, an air booster, a gas amplifier, an air booster pump, and an air booster valve. Pressurization requires a power source, so this is a pneumatic booster product that belongs to the power source and does not belong to the electric booster product;

Second, the principle of air booster

According to the principle of classification: belonging to the reciprocating piston pump, according to the law of conservation of energy, when the output pressure and the driving gas source reach a certain multiple relationship, the air booster will stop working, when the output pressure and the driving end of the gas source is not When in balance, then the air booster will continue to work until the pressure is balanced. Its principle of action is similar to that used in daily life. It belongs to the pressure category and is similar to the piston air compressor.

Third, the structure of the air booster

The output pressure of the air booster is a multiple relationship with the driving air pressure. The general structure is divided into three groups: a pressurized cylinder, a cylinder, and a reversing valve;

The reversing valve is a key core component for controlling the reciprocating movement of the driving piston. The driving piston and the high-pressure piston inside the driving cylinder are connected by a bearing, and the reversing valve can freely control the reciprocating movement of the piston when the reversing valve works. Similar to booster cylinder (one output unit: N, one output pressure unit; bar)

Four, air booster output pressure calculation

The air booster is a pneumatic booster product, which requires gas to drive it (3-8bar). Then the output pressure is a multiple of the drive gas. Take the Fiat ZTV02 air supercharger as an example, the output pressure and the drive air pressure Doubled relationship;

When the driving pressure is 6bar, the output pressure is 6 times 2 equals 12bar;

V. Air booster output flow

The output flow rate of the air booster is proportional to the drive air pressure. The higher the drive air pressure (2-8 bar), the greater the output flow rate and the standard flow rate when the flow rate is zero at the output of the air booster pump.

Sixth, air supercharger application range

(1) The local pressure adjustment of the factory requires a relatively large pressure requirement for a certain factory, but the factory air supply setting pressure cannot reach the equipment pressure requirement.

(2) The factory's air pipeline is too long, and there is fluctuation in the pressure before reaching a certain equipment;

(3) Cylinder assisted boost;

(4) Thimble hot runner air booster

(5) Insufficient pressure during lathe tool change

(6) Insufficient air pressure when the valve is opened (used frequently by brewery)

(7) The arm pressure needs to be higher than the factory pressure

(8) Mold cylinder blow molding

(9) Airtight pressure test of valve pipe

(11) CNC (CNC Wash) Pneumatic Cutter Head Pressurization

(12) Pressure for lifting and replenishing various pneumatic components

(13) Insufficient power source during valve test

(14) Impurity purging in laser cutting machine

(15) Explosion destructive test of high pressure hose

(16) Gas-assisted injection molding in the mold industry

(17) High-pressure air compressor cannot be configured, but high pressure output must be maintained

(18) Drive fluid media transport from the bottom to the top

(19) Instead of an expensive foreign import air booster

(20) Pneumatic components in large equipment require air pressure support

Seven, the advantages of air booster

(1) Small and easy to carry

(2) No spark, can be used in explosive places

(3) No power, low energy consumption

(4) Simple operation and easy maintenance

(5) Less seals, no oil lubrication

(6) Can be driven with a variety of gases, such as nitrogen, air, oxygen, helium, natural gas, etc.

(7) Automatic pressure keeping, regardless of any reason causing the pressure of the circuit to decrease, the FIAT air booster will automatically open the supplementary leakage pressure to keep the pressure in the circuit stable.

(8) Wide range of applications. All air source pressures are not high enough and unstable. Fiat air boosters can be used.

(9) higher comprehensive cost-effectiveness

(10) Variety of types, for all levels of pressure demand, there are various supercharger air booster products for their choice
