What is the venturi tube, what is its main function, and what is the general material? Thanks!

The venturi tube is an abbreviation for venturi tube, and the principle of the venturi effect is that when the wind blows through the barrier, the air pressure near the port above the leeward side of the barrier is relatively low, resulting in adsorption and resulting in the flow of air.

The principle of the venturi tube is actually very simple, it is to change the air flow from coarse to thin to speed up the gas flow rate, so that the gas forms a "vacuum" area behind the venturi outlet. It conveys the powder by means of an air flow.

There are many functions, mainly to use its injection and suction effect, such as vacuum cleaners, powder conveyors, coolers, flow meters, dryers, etc. This principle is also the principle of injection pumps in the chemical industry, so the materials mainly depend on the application place, including iron, aluminum alloy, and plastic nylon.

The venturi tube is made of iron, aluminum alloy, stainless steel and other different materials of various specifications of high-quality venturi tube, the iron venturi tube is made of 1 mm thick steel plate stretched at one time, the tensile strength meets the requirements of use, the fatigue strength is better than the cast aluminum venturi tube, especially will not be broken and cause serious mechanical accidents; The venturi dust removal skeleton has a smooth and smooth arc inside and outside, which is convenient for air flow. Venturi specifications 110, 115, 120, 125, 130, 135, 140, 145, 155, etc., skeleton joints and mouth bottoms are also the same specifications, all specifications of venturi specifications height is 130, small head diameter 60, large head diameter according to the skeleton specifications 145, 170

Venturi tubes

It's a venturi.

Abbreviation, Venturi effect.

When the wind blows through the barrier, the air pressure near the port above the leeward side of the barrier is relatively low, resulting in adsorption and air flow.

The principle of the venturi tube is actually very simple, it is to change the air flow from coarse to thin to speed up the gas flow rate, so that the gas forms a "vacuum" area behind the venturi outlet.

Features It can realize the conveying of powder by air flow.

The main thing is to use its injection and suction effect, such as a vacuum cleaner.

Powder conveying, coolers, flow meters, dryers, and much more. Chemical industry.

The injection pump is also based on this principle, so the material mainly depends on the application place, there are various iron, aluminum alloy, plastic nylon.

The lift of the aircraft also comes from the effect produced by the venturi. On the upper surface of the wing, the air flows faster than the lower surface, creating lift.

Iron venturi tube is generally used on the dust removal skeleton and filter cartridge, which is generally made of 1 mm thick steel plate and made by stretching at one time, which is characterized by smooth and beautiful appearance, stable and reliable quality, and effective lifting.

High dust collector efficiency and filter bag service life.

Iron venturi.

1. The function of the venturi tube is to induce secondary airflow.

When the dust is cleaned in the filter bag inside the dust collector, the secondary air that is 5 8 times the sprayed compressed air is induced to enter the filter bag of the dust collector when the high-speed air collapse wax flow passes through the venturi tube, resulting in the instantaneous rapid expansion of the dust removal filter bag, and the dust accumulated on the filter bag of the dust collector falls off due to the reverse action of the air flow of the dust collector. The venturi tube greatly improves the intensity and effect of pulse injection, reduces the amount of compressed air, and saves energy.

2. The venturi tube can play a role in protecting the filter bag.

The most obvious feature is that when the venturi inlet pressure remains constant, when the outlet pressure is reduced to a certain extent (the venturi pressure loss is greater than the initial cavitation pressure loss), cavitation occurs in the venturi throat, and when the outlet pressure is further reduced, the cavitation zone gradually expands and becomes deep cavitation.

The most obvious feature after cavitation is that the flow rate of the venturi is not affected by the outlet pressure and the downstream pressure of the venturi, but only depends on the pressure of the inlet, and the flow rate can be increased by increasing the inlet pressure, and the downstream pressure pulsation is isolated by the venturi and will not be transmitted to the upstream of the venturi, preventing the pressure oscillation of the whole pipeline.

The venturi tube is to change the air flow from coarse to thin to speed up the gas flow rate, and the negative gas forms a vacuum area behind the venturi outlet. It conveys the powder by means of an air flow.

The principle of the venturi effect is that when the wind blows through the obstruction, the air pressure near the port above the leeward side of the obstruction is relatively low, resulting in adsorption and silver Qi leading to the flow of air. The principle of the venturi tube is actually very simple, it is to change the air flow from coarse to thin to speed up the gas velocity, so that the gas forms a "vacuum" area behind the venturi outlet.

The venturi tube is short for the venturi tube, which produces adsorption and causes the flow of air. The principle of the venturi effect is that when the wind blows through the barrier, the air pressure near the port above the leeward side of the barrier is relatively low, and the principle of the venturi tube is actually very simple, it is to change the air flow from coarse to thin to speed up the gas flow rate, so that the gas forms a "vacuum" area behind the venturi outlet. It conveys the powder by means of an air flow.
