Have you ever understood the high-pressure water-cooled Roots blower? The reason why it has been widely used in the market is because of its stable performance. Key components such as fan rotors, casings, wall panels, and shafts are all equipped with advanced CNC machining equipment, and the impeller does not need to be completely interchangeable during assembly. The second is that it adopts high-precision and high hardness synchronous gears, which not only improves the lifespan of the fan. The third factor is low noise. The intake and exhaust ports of the fan adopt a spiral shape, allowing the intake and exhaust processes to enter sequentially in the direction of the spiral line, avoiding the pulsating noise and vibration that instantly erupts when the old fan exhausts. Are you clear about its working principle after understanding its characteristics?

高压水冷罗茨风机两根轴上的叶轮与椭圆形壳体内孔面，叶轮端面和风机前后端盖之间及风机叶轮之间，二者始终保持微小的间隙，在同步齿轮的带动下风从风机进风口沿壳体内壁输送到排出的一侧。

The impeller on the two shafts of the high-pressure water-cooled Roots fan is connected to the hole surface in the elliptical shell, and there is always a small gap between the impeller end face and the front and rear end covers of the fan, as well as between the fan impeller. Driven by the synchronous gear, the air is transported from the fan inlet along the inner wall of the shell to the exhaust side.

两只转子均固定於一组同步齿轮上，因此转动时，汽缸和转子间维持着相当微小的间隙，使其不互相接触，一般情形其间隙大约在十分之几毫米。因为彼此不相摩擦，故可以高速运转而获得大的风量或排气速度。在由叶轮和壳体和壁板包围的封闭空间)从进气口到排气口的运动过程中，壳体或壁板上的进气口被预先引入内部高压气体使得在基元容积与排气口连通之前内部压力逐渐达到或接近排气口压力的平衡，这就是它整个工作的过程。

Both rotors are fixed to a set of synchronous gears, so when rotating, a relatively small gap is maintained between the cylinder and rotor, preventing them from touching each other. Generally, the gap is about a few tenths of a millimeter. Because they do not rub against each other, they can operate at high speeds to obtain high air volume or exhaust speed. During the movement from the inlet to the exhaust port in a closed space surrounded by the impeller, shell, and wall panel, the inlet on the shell or wall panel is pre introduced with internal high-pressure gas, so that the internal pressure gradually reaches or approaches the balance of the exhaust port pressure before the primitive volume is connected to the exhaust port. This is the entire process of its operation.

罗茨风机已被广泛用于污水处理、水产养殖、气力输送、真空包装、洗煤、助燃、增压、铸造、矿山、冶金、化工、轻工、建材、电力、面粉、喷砂、真空等领域。

Roots blower has been widely used in sewage treatment, aquaculture, pneumatic conveying, vacuum packaging, coal washing, combustion support, pressurization, casting, mining, metallurgy, chemical industry, light industry, building materials, electricity, flour, sandblasting, vacuum and other fields.
