High pressure horizontal Roots blower

The Longgu high-pressure horizontal Roots blower is mainly composed of two three bladed rotors, a casing, and two parallel shafts. The casing can be divided into three categories: those with water cooling, those with air cooling, and those without cooling devices. The transmission mechanism is equipped with two gears of exactly the same style and size at the same end of the two shafts, which mesh with each other, directly connecting the driving shaft to the electric motor and driving the driven shaft to rotate in opposite directions through the gears. The centerlines of the two rotors of the horizontal Roots blower are in the same horizontal plane, and the airflow enters and exits vertically, resulting in high volume utilization, compact structure, high efficiency, and easy use and maintenance.

Introduction to Wind Turbine

The Longgu high-pressure horizontal Roots blower adopts a sealed dust-proof design, which can prevent dust from entering and has a long service life. Its two rotor centerlines are in a unified horizontal plane, and the airflow enters and exits vertically. Between the impeller and the shaft.

Performance Characteristics

1. High pressure horizontal Roots blower has a wide range of applications, with dual functions of suction and blowing. It can be used for both suction and blowing;

2. Low internal friction, able to operate normally under low or no oil conditions, and the transported gas is not easily contaminated and clean;

3. Low noise and high environmental efficiency;

4. Easy to maintain: with fewer consumables, convenient maintenance, and low cost;

5. Low mechanical wear and long service life.

Difference between vertical and horizontal Roots blowers

The structural forms of Roots blowers are divided into horizontal and vertical types. The horizontal Roots blower consists of two three bladed rotors, a casing, and two parallel shafts. The casing can be divided into three categories: those with water cooling, those with air cooling, and those without cooling devices. The transmission mechanism is equipped with two gears of exactly the same style and size at the same end of the two shafts, which mesh with each other, directly connecting the driving shaft to the electric motor and driving the driven shaft to rotate in opposite directions through the gears. Each rotor rotates once and can expel twice the shadow volume of air, so the active shaft exhausts four times the shadow volume of air every rotation. The reasonable arrangement of the inlet and outlet of the Roots blower should be: upper inlet and lower outlet (for horizontal type), which can use high-pressure gas to offset some of the weight between the rotor and shaft, reduce bearing pressure, and minimize wear.

Vertical type: The centerlines of the two rotors of the Roots blower are in the same vertical plane, and the airflow enters and exits horizontally.

Horizontal type: The centerlines of the two rotors of the Roots blower are in the same horizontal plane, and the airflow enters and exits vertically.

Advantages of wind turbines

(1) Under normal circumstances, changes in pressure have little effect on air volume, and the speed of the fan is directly proportional. Therefore, Roots fans are basically of constant capacity;

(2) No pulsation during suction and exhaust, no need for buffer gas tank

(3) Small footprint, easy to arrange and install;

(4) There should be a gap of 0.2-0.5mm between the rotor and the transfer, and between the rotor and the housing, without friction, allowing the airflow to contain a certain amount of dust;

(5) Compared with hydraulic jet pumps and water ring vacuum pumps, there is no problem of "exhaust with water";

(6) Reliable operation, easy maintenance, and durability.
