3、HDV type bottom conveying pump function

HDV type bottom conveying pumpmultifunctional, with functions such as powder conveying, environmental protection and dust removal, pneumatic ash conveying, material handling and environmental protection and dust removal，the main structure includes pump body, air evacuation valve, intake valve, control system and fluidizer，it has the characteristics of large conveying capacity, automation, flexible layout, convenient maintenance and omniseal，the product looks beautiful.，at work,When the material enters the pump body and is full, it is gasified to make the material form a fluidized state and smoothly enter the mixing chamber. At the same time, the compressed air is ejected at high speed through the jet nozzle and fully mixed with the fluid material. The high-speed airflow drives the material to pass through a specific pipeline, which converts the kinetic energy of compressed air into pressure energy, and at the same time, the air and the material are mixed again, so as to improve the speed of the material and make it move forward along the conveying pipeline, thus achieving the purpose of conveying powdery materials.。

5、Working principle of HDV type bottom conveying pump

The principle of HDV type bottom conveying pump is introduced as follows:

1. Conveying stage

When the material in the pump body reaches a certain amount, the feed valve is closed. Then, introduce compressed air into the pump body. The compressed air expands rapidly in the pump body, so that the material is fully mixed with the air, and the material is pushed along the conveying pipeline under the action of air pressure.

2. Conveying stage

When the material in the pump body reaches a certain amount, the feed valve is closed. Then, introduce compressed air into the pump body. The compressed air expands rapidly in the pump body, so that the material is fully mixed with the air, and the material is pushed along the conveying pipeline under the action of air pressure.

3. Feeding stage

The feed valve of the HDV type bottom conveying pump is opened, and the material enters the pump body of the HDV type bottom conveying pump under the action of gravity or other feeding devices. In this process, the pressure inside the pump body is basically the same as the external atmospheric pressure to ensure the smooth entry of materials.

4. Discharge stage

After the material is transported to the destination, it is discharged through the discharge valve. The destination can be a silo, a reaction kettle and other equipment for receiving materials. After discharging, the whole HDV type bottom conveying pump system can enter the next feeding-conveying-discharging cycle.

5. Conveying stage

When the material in the pump body reaches a certain amount, the feed valve is closed. Then, introduce compressed air into the pump body. The compressed air expands rapidly in the pump body, so that the material is fully mixed with the air, and the material is pushed along the conveying pipeline under the action of air pressure.

6、Structural characteristics of HDV type bottom conveying pump

The HDV type bottom conveying pump structure is introduced as follows:

1. Air intake device

Comprises an air inlet pipeline, an air inlet valve and other components. The air inlet pipe is used to introduce compressed air into the pump body, and the air inlet valve can control the flow and pressure of compressed air. The performance of air intake device directly affects the conveying speed and efficiency of materials.

2. pump body

The core part of the HDV type bottom conveying pump is used to contain materials. The pump body is generally a cylindrical pressure vessel, and its material is usually carbon steel or stainless steel to ensure sufficient strength to withstand internal pressure. In the design, the volume of the pump body should be considered, which will be determined according to the actual delivery requirements.

3. Feed valve and discharge valve

The feed valve is used to control the material entering the pump body, and the discharge valve is used to control the material discharging from the pump body. These valves are usually ball valves, butterfly valves or gate valves, which require good sealing to prevent material leakage and gas leakage.

4. level-sensing device

Used to detect the material level in the pump body. Common level gauges include capacitive level gauges and ultrasonic level gauges. Through the material level gauge, the feeding amount can be accurately controlled to avoid the situation that the pump body is too full or the material is insufficient.

5. Air intake device

Comprises an air inlet pipeline, an air inlet valve and other components. The air inlet pipe is used to introduce compressed air into the pump body, and the air inlet valve can control the flow and pressure of compressed air. The performance of air intake device directly affects the conveying speed and efficiency of materials.
