Full lineup of helical blowers for a variety of applications

ShinMaywa helical blowers are the latest in roots-type blowers which incorporate low noise technology. We use our outstanding technology to meet the high-level needs of the world of industry by also giving consideration to environmental problems such as noise.

Comprehensive low-noise design The design suppresses vibration in the low-frequency range where blower noise is generated. The reason why ShinMaywa blower noise suppression is successful is as follows. The main sources of blower noise include sources such as "pulsating noise of rotor", followed by "gear meshing", and then "bearings". Of particular note is the pulsating noise (roots noise) generated by the air which is displaced by the rotors. At ShinMaywa we have successfully used "3-lobe helical rotor" to greatly reduce the amount of this pulsating noise. Furthermore, ShinMaywa technology for suppressing sound is not limited to just the rotors. We have also devised a torsional shape for the teeth gears which drive the rotors.

Q A

What is the difference between helical-type rotors and spur-type rotors?

ShinMaywa helical rotors have three lobes twisted in a spiral shape, so that they displace the air continuously to prevent pulsating noise from occurring.

Q

Because there is only a small gap between the twisted rotors and the rotor housing, is high-precision machining required?

Q A

When the rotors are twisted, does the amount of blown air drop for each rotation?

Q A

How do you inspect the twisting of the precision rotors and the curve of the teeth?

The tips of the rotor teeth 3-lobe involute type 3-lobe arc type used by ShinMaywa are slim. Therefore, even though the rotors are twisted, the amount of air blown per rotation is more than spur type blowers.

The shape of the rotor teeth is inspected using 3-dimensional measuring equipment. Measurement results are output to a plotter. Thorough quality control is carried out to ensure that the curvature of the teeth is within the allowable tolerances.

A

A high-precision machine called a "milling machine" is used for machining the screws and the gears, so that the rotors are manufactured with high precision and high reliability.

[Processing method] The rotor turns slowly to match the rotation of the cutter. The cutter moves forward in the direction of the arrow while rotating. Cutter ●Rotor processing using a milling machine

In the high-frequency range (200 to 5,000Hz), the noise is absorbed by the glass wool in the wall of the machine chamber for both helical-type and spur-type rotors.

In the low-frequency range (50 to 160Hz), it can be seen that the noise volume is higher for spur-type rotors than for helical-type rotors. This is because noise in the low-frequency range is not absorbed by the glass wool and leaks outside the machine chamber. The low-noise design of ShinMaywa helical blowers significantly reduce the amount of noise output in the low-frequency band, which is the main cause of noise. This technological ability provides a large difference in the amount of noise in the low-frequency range.

Easy maintenance

Improved durability The blower durability has been improved through the use of a larger bearing and the lowering of motor speed, as well as the reduction of temperature rise.

Variable Frequency Driver (VFD) controlled air flow rate

Fluororubber is used for the oil seal. The lubricating system is protected with the labyrinth seal which is effective to prevent oil leakage.

The bearing is fixed with a C-type retaining ring. The timing gear can be disassembled easily by a gear puller. A ball bearing is employed instead of a roller bearing, to avoid damaging the inner case during reassembly. Thus, the blower maintenance has been significantly simplified.

When installed near the workplace or in apartment blocks, it can greatly reduce the costs of noise-reduction measures.

VFD control system permits the motor speed to be easily changed electrically. When VFD control is used with the blower, the air flow rate can be varied freely. Also, by using a suitable control device with the blower, it is possible to implement automatic control of the blower. (The controllable range of motor speed depends upon blower working conditions. When using a VFD with the blower, consult your nearest dealer.) ※The VFD to be used should be a constant torque type. 3

General-purpose motor and VFD (V/F control)

Selecting a VFD-Controlled Model

Ⓐ Ⓐ

VFD control is available for all models. This feature allows precise control of the air flow rate to accommodate water treatment volumes that vary over season and time.

Ⓑ Ⓑ

Operation at excessively slow speeds with the VFD may allow high-temperature compressed air to leak into the suction side through Clearance (1) between rotors and Clearance (2) between rotors and housing wall, as illustrated below. This may result in a temperature rise that exceeds the bearing temperature limit, resulting in a blower failure.

Blower (b)

General-purpose motor and VFD (Vector control) Both blowers (a) and (b) are usable within the range from Ⓐ to 60 Hz. The blowers are not usable below Ⓐ because the blower temperature will rise. Notes:Ⓐ indicates the lower limit of the frequency control range based on the blower temperature rise. 1) Blower torque remains constant when the motor speed is reduced because of the blower’s constant-torque characteristic. 2) When selecting a VFD, ensure the rated output of the VFD is equal to or greater than the rated output of the motor. 3) The control range of the VFD starts at 60 Hz regardless of the frequency of the power source. The control range depends on several factors including the application, motor output, and model.

Consult us if you require VFD control. We can provide an VFD calculation sheet.

Differences between ARH-E type equipped with IE3 motor and type equipped with IE1 motor

Significant differences in motor size and weight • Motor outer dimensions: The frame size of IE3 motor does not differ from the IE1 motor, so it can be installed to the blower with IE1 motor. However, with the IE3 motor, the diameter and length of motor both tend to be larger. Because of this, the outer dimensions will be larger for some models, and so check the matching dimensions for cables, etc. and make sure that there is no interference with surrounding equipment during installation. • Motor weight: As mentioned above, the motor size is larger, and so the weight of the motor has also increased as a result. (However, there is no need to reselect the anti vibration rubbers for ShinMaywa helical blowers as a result of this weight increase.)

Starting current increased • With the IE3 motor, the starting current tends to be larger. As a result of this, it will be necessary to inspect equipment such as circuit protector to make sure they are appropriate. In addition, it is also possible that the capacity of the electromagnetic switch may need to be changed when replacing the motor.

(Points to note if replacing your previous model with the IE3 motor) Increase in rated operating speed of motors • With the IE3 motor, the rated operating speed will increase. When replacing an IE1 motor with an IE3 motor, the air volume and output power increase as a result of the increased operating speed. Customers using the motor at around the maximum rated current (95% or more of the rated current), and looking into replacing their motors should notify ShinMaywa, as there is a possibility that excessive power may be generated as a result of the increased air volume.
