Product Description

Product Description

ZRSR Roots blower
Product introduction
Roots blower is a two-rotor compression machine, the axes of the two rotors are parallel to each other.
The rotor is composed of an impeller and an shaft, and there is a small gap between the impeller and the impeller, the impeller and the shell and the wall plate to avoid contact friction.
The two pairs of rotors are driven by an electric motor through a pair of synchronous gears and rotate at equal speeds in opposite directions.
With the mutual meshing of the two gears, the inlet and outlet of the blower are not directly connected.
The impeller is enclosed with the casing and the wall panel to form a closed elementary volume, so as to achieve the effect of conveying gas.
Main features and uses
1. The fan inlet adopts spiral shape.The inlet and exhaust air shielding line of the casing is cut into the spiral, and the triangular inlet and exhaust outlet formed by the smooth surface line at the top of the rotor is cycled open through the rotation of the rotor.
2. The rotor adopts a special shape and is mass-produced by precision CNC machine tools to ensure the mutual clearance between the rotor and the components and further improve the efficiency of the fan.The rotor part is all carried out before assembly and static balance test, so the vibration is very small.
3. Using high-precision driving gear, not only the service life is extended, but also the realization of low noise.
4, the output air is clean, does not contain any oily dust.There is no need for oil lubrication in the housing, and the structural design is adopted to avoid mixing bearing and gear oil into the housing.
5. With the establishment and improvement of the company's quality management and production management system, the components are interchangeable.
This reduces production costs and shortens the lead time.
Under normal circumstances, the fan has a proper amount of inventory, which can be delivered on the same day.
Roots blower is mainly used in sewage treatment, aquaculture, pneumatic conveying, powder conveying, cement, chemical industry, casting, electroplating tank, food vacuum packaging and other industries.
1. The performance table lists the fan model, caliber, speed, exhaust pressure, flow rate and required power.
2. The performance table shows different motor output power in different colors, please select the corresponding power motor.
3. The parameter performance of some fans is repeated.From the economic point of view, small type fan should be selected;From the point of view of noise, large fan models should be selected.
Flow rate
The flow rate (air volume of the blower) shown in the performance table refers to the inlet flow rate of the blower at the standard suction state, that is, when the temperature is 20ºC, the pressure is 101.325kPa, and the relative humidity is 50%. The commonly used units are m/min and m '/h(the unit conversion table is as follows).
Stress
The gas pressure at the inlet and exhaust flange of the blower is called the intake pressure and exhaust pressure. For Roots blowers, the pressure usually refers to the difference between the inlet and exhaust pressure of the blower, which is the boost pressure, also known as the pressure difference. Commonly used units Pa and kPa. The pressure conversion table is as follows:
Rotational speed
The number of revolutions of the blower spindle in unit time is called the speed of the blower. The unit can be r/min or rpm, collectively referred to as: revolution per minute.
Shaft power
The power transmitted from the motor to the blower spindle becomes the blower shaft power. The unit is usually W or kw. Power conversion table
