Why Choose Lingyu 5.5 kw Belt Driven Rotary Screw Air Compressor
(1) Adopt High Quality Drive belt
이것 7.5 hp screw compressor uses a heavy-duty belt. It has a long life and high reliability. 게다가, it can maintain constant belt tension in every phase of operation. So this small screw compressor has consistently good drive efficiency. 게다가, there is a convenient tensioning device. 그러므로, this makes maintenance work easy.
(2) High Performance Compressor Airend
우리의 5.5 kw air compressor is with Baosi airend. Baosi is one of the best airend manufacturers in China. Its rotors are of large diameter structure. And it uses the advanced 5:6 tooth profile. So it ensures effective compression efficiency and sufficient air volume. 뿐만 아니라, the bearings are durable SKF heavy-duty bearings. They have a service life of up to 100,000 시간.
(3) Reliable And Intelligent Control
This belt driven screw compressor comes with intelligent microcomputer control technology. So you can fully monitor and manage the entire air compressor under command. Unattended operation is possible. 게다가, there is a user-friendly human-machine interface. It can display commands and parameters. The screw type air compressor has a self-diagnostic fault and alarm function.
(4) Reasonable System Structure Design
In order to achieve better heat dissipation, our designers use a larger heat exchanger with a large area. This is why our air compressors have good heat dissipation efficiency and lower noise levels.
Belt Drive Rotary Screw Air Compressor vs Direct Drive
Belt driven screw compressors can use pulleys of different diameters to change the speed of the rotor. The direct drive screw air compressor is different. It refers to the way that the motor shaft drives the rotor through the transmission of the coupling and the gearbox. These two methods are good transmission types. But what is the difference between the two?
(1) Belt Driven Screw Compressor
The connection drive between the air compressor motor and the airend is connected by a belt. 예를 들어, 우리의 5.5 kw air compressor uses this kind of transmission. The advantages of the belt drive mode are as follows: the structure is relatively simple. 게다가, the economy and practicability are good. It is also easier to replace later if necessary. 게다가, we can quickly change the pressure according to the requirements of users. The disadvantage of belt drive is that the belt is easy to wear after a long time of use. This can cause slippage. The transmission efficiency is slightly lower than other transmissions.
(2) Direct Drive Rotary Screw Air Compressor
The screw compressor motor is connected with the airend through a coupling. 예를 들어, our big industrial air compressors generally use the direct drive type. The motor and the airend run at the same speed. 그러므로, the service life is longer. 게다가, its direct transmission efficiency is higher. 게다가, it does not require complicated maintenance work. Only need to replace the rubber spring pads of the coupling. Due to the high transmission efficiency, the direct drive is becoming more and more popular in the market.
FAQ
1분기: Is your 5.5 kw air compressor belt drive or direct drive?
A1: 우리의 7.5 hp 5.5 kw screw air compressor is belt driven.
2분기: What’s the voltage of your 7.5 hp screw compressor?
A2: The regular voltage of our industrial rotary air compressor is 380V 50HZ 3-phase. 물론, if you need other voltages, such as 220V, 460V, 440V 60HZ, we also manufacture them.
3분기: How to replace the belt of rotary screw air compressor?
A3: Belt driven screw compressor has many advantages. But we need to replace the transmission belt. 첫째로, stop the belt drive rotary screw air compressor. 둘째, loosen the mounting bolts on the airend. 기후, rotate the adjusting screw. Adjust the belt to the correct tightness. 마지막으로, tighten the airend fixing bolts. Need to pay attention. Do not splash lubricating oil on the belt or pulley to prevent the belt from slipping.
4분기: Can I also buy some spare belts with this 5.5 kw air compressor?
A4: Sure. We usually advise customers to purchase some belts for replacement in the future.
