DINKONDA GLOBAL Power Plants Special BV Series Three Leaf Roots Vacuum Unit Negative Pressure Suction (Roots Vacuum Pump) Roots Blower

DINKONDA GLOBAL Power Plants Special BV/BV-H Series BV Type Three Leaf Roots Vacuum Unit Negative Pressure Suction (Roots Vacuum Pump) Roots Blower

Product Introduction
The BV type negative pressure Roots blower belongs to the three blade Roots vacuum unit, specially developed for negative pressure suction conditions. It relies on the three blade rotor to achieve vacuum suction through forced volumetric suction. Unlike the positive pressure supply Roots blower, this machine has a working mode of negative pressure at the inlet and slight positive pressure at the outlet, which can complete gas suction, material negative pressure conveying, and system vacuum suction operations. The whole machine integrates inlet and outlet mufflers, common bases, and belt protection devices, and is supplied in a complete set. It is widely used in sewage treatment negative pressure aeration, powder negative pressure conveying, vacuum dehydration, exhaust gas suction and other working conditions. The equipment runs stably with small fluctuations in vacuum degree, and can adapt to continuous and uninterrupted operation requirements.

Structural Composition
1. Main pump body: Three leaf rotor structure, high-precision rotor processed by CNC, synchronous gear transmission, precise control of pump chamber clearance, ensuring negative pressure suction capacity; The shell is cast as a whole, with strong rigidity and good pressure bearing performance.

2. Drive motor: Industrial three-phase asynchronous motor, driven by a belt with the host, equipped with a yellow safety net cover, which provides enclosed protection for the drive belt to ensure the safe operation of the equipment.

3. Inlet and outlet muffler assembly: Pipe type mufflers are installed on the inlet and exhaust sides respectively, effectively suppressing the noise generated during negative pressure suction and exhaust processes, and reducing the overall noise level of the machine.

4. Integrated common base: The steel welded integral frame integrates the main engine, motor, and sound-absorbing tube into the same base, and the factory completes the alignment to reduce the workload of on-site installation and leveling.

5. Accessory interface components: flange type inlet and outlet interfaces for easy pipeline docking; Reserve installation interfaces for pressure gauges and safety valves, and configure negative pressure protection components to prevent equipment damage caused by excessive negative pressure operation.

Product Features
1. Volumetric negative pressure suction: The flow rate is less affected by changes in vacuum degree, and can maintain a relatively stable suction volume under negative pressure conditions, making it suitable for processes that require stable suction flow rate.

2. Complete integrated design: The host, muffler, protective cover, and base are shipped as a complete set, and users only need to connect the pipeline and power supply to put them into use, shortening the project construction period.

3. Complete safety protection: Install protective nets at the belt area to eliminate safety hazards; Can be equipped with negative pressure overflow protection device to avoid system blockage and extreme negative pressure damage to the fan.
Strong continuous operation capability: The rotor, bearings, and synchronous gears are selected according to 24-hour continuous working conditions, suitable for industrial all-weather uninterrupted production.

4. Convenient maintenance: The gearbox is externally mounted, making it easy to add lubricating oil and observe the oil level; The belt drive structure can adjust the suction parameters of the unit by replacing the belt pulley, adapting to different process requirements.

5. Wide adaptability to working conditions: It can be used for clean air suction, and after material upgrades, it can also be adapted to exhaust gas extraction scenarios containing a small amount of water vapor.
