What is a venturi tube and what is a venturi tube used for?

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.

Venturi tubes

It is an abbreviation for Venturi tube, and the Venturi effect is based on the principle 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 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.

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

It mainly uses 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, plastic nylon, and various types.

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.
