ทำไมต้องเลือกหลิงหยู 10 แรงม้า 3 Phase Screw Air Compressor
① Reliable Quality
Our twin screw air compressor uses good spare parts. ประการแรก, the airend is the most famous China brand ~ Hanbell. The bearings are also SKF brand. The airend has two years warranty time. ประการที่สอง, the three air compressor filters also have high quality. The lubricant oil is Shell brand. นอกจากนี้, it uses a special low-speed motor for air compressors. The efficiency is higher than similar products. It can ensure trouble-free operation.
② Stable Air Pressure And Airflow
Because of its simple structure and quality parts, it has excellent stability. A double screw air compressor is not prone to failure. Air production is sufficient. The capacity of a 10 แรงม้า 3 phase screw air compressor is 1.2m³/min.
③ 100% Transmission Efficiency
นี้ 7.5 kw screw air compressor uses the direct connection structure. So there is no loss and it has low maintenance costs. It is easy to disassemble, and significantly reduces downtime.
④ Intelligent Control System
If no air consumption for a long time, the twin screw air compressor will automatically stop. When the air is restored, it will start again. นอกจาก, it can display various faults. It can ensure the reliable operation of the air compressor to the greatest extent, and improve its service life.
⑤ OEM/ODM Customization Ability
ประการแรก, we can print your logo on the 10 แรงม้า 3 phase screw air compressor. ประการที่สอง, if you need special voltages, they are available. นอกจากนี้, if you want to use other brand parts, เรายังปรับแต่งได้.
Single Screw vs Twin Screw Air Compressor
(1) Whole Machine Comparison
① Air compressor power is different
Assume the airflow is the same ~ 3m³/min. The single screw compressor power is 5.6~6.2KW. But the power of the double screw air compressor is a bit bigger: 6.0~6.6KW.
② Noise and vibration
Single screw: no vibration (steel coins can stand upright and not fall down). The noise is 60-68dB. Twin screw compressor: the vibration is greater because the forces cannot be balanced. The noise is 68-88dB. ตัวอย่างเช่น, the noise of a 10 แรงม้า 3 phase screw air compressor is 68dB.
③ Bearing durability
Single screw compressor: radial and axial balance. Long bearing life. Rotor bearing 30,000 ชั่วโมง. Star wheel bearing 50,000 ชั่วโมง.
Twin screw type compressor has no balance at all. The load of the second rotor is extremely large. The bearing life is short, generally: 8000-18000 ชั่วโมง. It needs professional personnel to replace the bearings.
④ Temperature
The exhaust temperature of the single screw compressor is <90องศาเซลเซียส. Twin-screw temperature <110องศาเซลเซียส.
(2) Usage Cost Comparison
① Electricity fee (calculated at 3m³/min)
Single screw: 35.62508=33600KW/h.
Twin-screw air compressor: 36.52508=39000KW/h.
② Normal maintenance fee
Assume both run for 30 ปี. The twin-screw machine needs to change the screw 5 ครั้ง. The cost is equivalent to 1.5 times that of buying a new airend.
The single screw only needs to change the star wheel 3 ครั้ง. นอกจาก, the price of the star wheel is quite low. The cost of this piece of single-screw is only about 10% of that of twin-screw. If it’s fixed speed drive 10 แรงม้า 3 phase screw air compressor, there are 4pcs or 6pcs bearings. AC airend has 4pcs bearings. And AB airend has 6pcs bearings.
③ Oil consumption
The single screw has a low operating temperature. So the oil itself is not demanding. Therefore the cost is low.
The twin screw air compressor runs at high temperatures. ดังนั้น, the requirements for oil are high. นอกจากนี้, high temperatures carbonize the oil. Need to replace oil many times. So the cost is high.
④ Bearing life (equal SKF bearing)
The bearing of the single screw compressor is replaced every 30,000 ถึง 50,000 ชั่วโมง.
The twin-screw compressor is changed every 8000-18000 ชั่วโมง.
(3) Different Working Principles
The former: single-screw rotor drives two symmetrically distributed star wheels to rotate. Screw groove and the inner wall of the casing form a closed chamber. Bring the air to the required pressure.
The latter: the airend consists of intermeshing rotors. When working, one rotor rotates clockwise. The other turns counterclockwise. So it generates the compressed air during intermeshing.
(4) Force Balance
Single-screw air compressor: the force balance is excellent. Screw bears radial and axial air forces. They can be automatically balanced. The star gear teeth bear the forces. So it requires that the star gear teeth have sufficient strength and rigidity.
Twin screw type air compressor: the screw rotor bears large radial and axial air forces. The air forces are unbalanced. อย่างไรก็ตาม, it can improve axial force balance through structural design. There are no unbalanced inertial forces.
(5) Manufacturing Cost
Former: it can use ordinary bearings for screws and a star wheel. Manufacturing costs are lower.
Later: the load on the two-screw rotor is relatively large. ดังนั้น, it requires to use of high-precision bearings. Manufacturing costs are higher. For this 10 แรงม้า 3 phase screw air compressor, we can supply a good price. Different spare parts, different prices.
(6) Different Applicability
The former: it’s suitable for occasions with high exhaust pressure. It can also be made into a water-lubricated air compressor.
The latter: There are limitations in terms of rotor stiffness and bearing load. ดังนั้น, it can only be suitable for the medium and low-pressure range. The exhaust pressure generally doesn’t exceed 1.6Mpa.
คำถามที่พบบ่อย
ไตรมาสที่ 1: What’s the air capacity of your 10 แรงม้า 3 phase screw air compressor?
A1: When pressure is 7 บาร์, the airflow is 42 ซีเอฟเอ็ม.
ไตรมาสที่ 2: How about the oil content of your twin screw air compressor?
A2: It is less than 3 ppm. If you have a high requirement for air quality, you can add a refrigerated dryer and an adsorption air dryer.
ไตรมาสที่ 3: What’s the warranty policy for the twin screw type compressor?
A3: The machine has a year warranty time. And for airend, it’s two years. นอกจาก, we provide the technical service all the time.
ไตรมาสที่ 4: What’s the price of your 10 แรงม้า 3 phase screw air compressor?
A4: ประการแรก, this one is the fixed-speed drive air compressor. Its price is cheaper than the PM VSD type. ประการที่สอง, different spare parts, and different prices for choice. The AC airend with 4 pcs SKF bearings is cheaper than AB airend with 6 pcs SKF bearings. นอกจากนี้, our motor has two kinds: IP54 and IP23. So pls kindly tell us your specific requirements: fixed speed or variable speed, AC airend or AB airend, IP54 or IP23 class motor? ขอบคุณ!
Q5: How long is your production time?
A5: If a normal 380V 50HZ 10 แรงม้า 3 phase twin screw air compressor, it only takes 15~20 days. But if you have customization demand for voltage or color, the time will be a bit longer. It will take about 30~40 days.
