TECHNICAL SPECIFICATIONS 

 

 

(1) Unit performance measured according to ISO 1217, Annex C, Edition 4 (2009).

Reference conditions:

- Relative humidity 0%.

-Absolute inlet pressure: 1 bar (14.5 psi). - Intake air temperature: 20°C/68F.

FAD is measured at the following working pressures:

Fixed speed:

-75/8.6 bar versions at 7 bar.

- 10/10.4 bar versions at 9 bar.

For VSD: at their maximum working pressure.
 

(2) A-weighted emission sound pressure level at the work station (LpWSAd).

Measured according to ISO 2151: 2004 using ISO 9614/2(sound intensity scanning method).

The added correction factor (+/ 3 dB(A)) is the total uncertainty value (KpAd) conform with the test code.

 

Standards and certifications of RM
 

Atlas Copco Z-compressors are measured according to ISO 1217, Annex C, Edition 3, stipulating the FAD(Free Air Delivery) measurement at the outlet of the package, net of all losses.

Atlas Copco specifications correspond to the capacity and pres- sure that are effectively available to the user, not to the air vol- ume that is sucked in. Differences can be substantial.

Company Profile

Company Profile

Founded in 2012, Yongshunxing Compressor (Shanghai) specializes in the design and manufacture of dry oil-free air compressors, providing customers with various forms of oil-free air compressor solutions, and providing customers with full-cycle services for air compressor products.
The founding team members of the company have nearly 20 years of experience in the professional design and manufacture of oil-free air compressors, and have successfully provided various machine head supporting services and oil-free air compressors, and have been widely recognized and praised by customers. Yongshunhang promotes the wide application of oil-free screw air compressors by providing high value-added supporting oil-free main engines to the market, and helps users obtain high-efficiency and high-quality oil-free compressed air.

Remanufacturing service is a kind of full use of the original equipment investment, through professional design and optimization to achieve the restoration and improvement of the original equipment function. Through remanufacturing, it not only saves a lot of equipment investment for customers, improves capital utilization, but also saves a lot of raw material consumption for the society, and plays a positive role in reducing carbon emissions and reducing the greenhouse effect through full use of resources.
Yongshunhang has the talents and management experience required for air compressor remanufacturing, and has complete hardware conditions to ensure the quality and efficiency of air compressor remanufacturing. For example, the remanufacturing plant covers an area of 2,500 square meters, the power supply capacity of the test room is 500KVA, the cooling water system can reach 50 cubic meters per hour, the air inlet and exhaust volume can reach 75,000 cubic meters per hour, the standard flow detection is 120 cubic meters per minute, and it is equipped with noise and vibration detectors; The remanufacturing workshop is equipped with a dynamic balancer to calibrate transmission components such as gears, spindles and screws, and we have the following capabilities: (1) the overhaul and replacement capabilities of the machine head, especially the oil-free rotor spraying workshop and thickness gauge and meshing detector to ensure the meshing accuracy; (2) Special tooling for cooling system maintenance and pressure testing; (3) The ability to optimize and transform the control system, including the detection of special controllers and sensors; (4) Inspection of lubrication system, cleaning and maintenance of oil tank, pipeline and oil pump; (5) Motor overhaul and maintenance; (6) Refurbishment or replacement of the chassis.
The successful cases of remanufacturing include the remanufacturing of the water-cooled inverter air compressor with the model ZR315-8.6VSD, including the replacement of the inverter, the optimization of controller communication, the replacement of the cooler, the replacement of the high-rotor and the maintenance of the low-pressure rotor, the overhaul of the motor, the replacement of part of the sheet metal and the color of the whole machine, and the remanufacturing of the air-cooled power-frequency oil-free air compressor with the model ZT90 in the electronics industry to improve the exhaust pressure. The power of the whole machine is increased by replacing the motor, the centrifugal fan for cooling is replaced to increase the cooling air volume, and the control system and safety protection device are replaced. The above-mentioned remanufacturing reduces capital investment, saves more than 50% of the cost compared with the purchase of new equipment, and has won a very high evaluation from users.
