Advantages of Our 15 kw Screw Air Compressor
(1) Energy-saving
Compared with the power frequency air compressor, it can generally save energy by 10%~35%. แน่นอน, how much energy is saved depends on two aspects. นั่นคือ, the working conditions and the setting of the parameters of the inverter. The biggest factor is the working condition of the industrial air compressor. When the customer’s actual air consumption fluctuates greatly, then the energy-saving effect will be better. The direct data is the ratio of the no-load time to the total working time.
(2) Low Maintenance Cost
The soft start of the air compressor reduces electrical shock to the motor components. The starting current is small. ดังนั้น, it extends the lifetime of the motor. ในเวลาเดียวกัน, it also reduces the mechanical impact on the equipment. Correspondingly, it improves the service life of motor bearings, main engine bearings, and gearboxes.
นอกจากนี้, the energy-saving controller keeps the air compressor in a loading state most time. It reduces the action number of both solenoid valves and pneumatic components. ดังนั้น, the failure rate without these accessories becomes lower. นอกจากนี้, the reverse filtration time of the inlet filter is greatly reduced. It extends the filter lifetime of a 20 คอมเพรสเซอร์แบบสกรูของเอชพี.
(3) เสียงเบา
When the exhaust air volume decreases, the speed of the compressor motor slows down. So the noise is much less than when running at full speed. The unloading run time becomes less, venting noise is also reduced.
(4) Wider Exhaust Air Volume Adjustment Range
Permanent magnet motors can maintain extremely high motor efficiency at low speeds. ในเวลาเดียวกัน, it allows the max speed to exceed the upper limit of the rated speed. ดังนั้น, the adjustment range of exhaust volume can reach 15%-115% of the rated flow. So the application of a 15 kw air compressor will be more flexible.
(5) Higher Transmission Efficiency
Belt drive efficiency is typically 0.94 – 0.96. ของเรา 7.5 แรงม้า 5.5 kw screw compressor is belt drive type. นอกจากนี้, the direct drive efficiency is above 0.99. นี้ 20 hp rotary screw air compressor is a direct drive type. The permanent magnet motor does not have any mechanical friction loss or transmission loss. The transmission efficiency is 1.
How to Maintain Our Industrial Rotary Screw Air Compressor?
Regular maintenance can effectively reduce or avoid failures. So it can reduce the maintenance cost of 15 kw air compressor. ในเวลาเดียวกัน, it can avoid affecting the product quality. If the oil content in the exhaust air is unqualified, it will cause products to be scrapped. นอกจากนี้, it is also good for energy saving and consumption reduction. Bad operation of industrial air compressors often increases friction and energy consumption. ในท้ายที่สุด, it will affect the energy-saving effect of the screw air compressor.
(1) Air Compressor Air Filter Maintenance
It can filter out dust and other dirt in the air. The best time for maintenance is once a week. The specific method is as follows: ประการแรก, take out the air filter of 20 คอมเพรสเซอร์แบบสกรูของเอชพี. Then use a certain amount of compressed air to blow the inside out. Clean up the dirt on the surface of the part. ในที่สุด, wipe it clean with a clean cloth.
(2) Industrial Air Compressor Oil Filter Maintenance
For the new 15 kw air compressor, replace the oil filter after use for more than 500 ชั่วโมง. After that, we can change it every 2000 hours or so.
(3) Compressed Air Oil Separator Maintenance
The best replacement time is around 3,000 ชั่วโมง. But in the case of relatively bad conditions, it is necessary to shorten the replacement time. ในเวลาเดียวกัน, we need to take the oil separator out in due course for cleaning.
(4) Screw Compressor Lubrication Oil Maintenance
The quality of lubricating oil directly determines the performance of the oil-injected screw compressor. Good oil can make the machine run normally and efficiently. And for a new industrial compressor, it is best to replace the oil after 500 hours of use. After that, we can replace it after every 2,000 ชั่วโมง.
(5) 20 HP Rotary Screw Air Compressor Air Cooler Maintenance
The cooler can cool down and dissipate heat. After long use, the 15 kw air compressor will become hot. If there is a problem with the cooler, the screw compressor will collapse. นอกจากนี้, the air cooler has a special structure. This makes it prone to dust accumulation. So it is necessary to regularly clean the dust.
คำถามที่พบบ่อย
ไตรมาสที่ 1: How many CFM is a 20 เครื่องอัดอากาศแบบสกรูของเอชพี?
A1: Different pressures, different air flows. If the pressure is 8 บาร์, the airflow of the 15 kw air compressor is 2.2m³/min. นั่นคือ, the airflow is 77 ซีเอฟเอ็ม. And if the pressure is 7 บาร์, the airflow is 2.5m³/min (≈80 cfm).
ไตรมาสที่ 2: What’s the average lifespan of a rotary screw air compressor?
A2: Under normal circumstances, it is no problem to use it for 10 ปี. แน่นอน, we have to do a good job of daily maintenance.
ไตรมาสที่ 3: What’s the delivery time of your 20 hp เครื่องอัดอากาศแบบโรตารี่แบบสกรู?
A3: Different voltages and configurations, different delivery times. If 380V/50HZ 15 kw air compressor, our delivery time is 15~20 days. But if special custom screw compressor, the delivery time is about 35~40 days. ตัวอย่างเช่น, many customers need 220V/415V/440V/460V and 60HZ air compressors. The lead time is longer than 380V/50HZ screw compressor.
