Single screw water lubricated air compressor product introduction

2026-04-10Views:

The oil-free and water-lubricated single-screw compressors produced by Shanghai Granklin Group have unparalleled advantages in terms of gas quality, energy saving, easy maintenance and reliability, and are widely used in food and beverage, medicine and medical care, and precision manufacturing., Instrumentation, fuel cells, microelectronics, biology and other industries with extremely high gas demand.

Seiko Intelligent, Granklin Water Lubricated Air Compressor

single screw host

100% oil-free air quality, energy saving and high reliability. Because the single screw structure is more energy-efficient under the same air output, it has become the mainstream water lubricated air compressor in the market, which is easier to maintain and has lower noise.

1. Frequency conversion constant pressure output of compressed air. If the outlet pressure level of compressed air is required to be 6bar, we can set the constant pressure to be 6bar, and adjust the operating frequency according to the customer's air demand to achieve the purpose of adjusting the operating power. Oil-free piston compressors need to set the pressure level to be 6 ~ 8bar, the pressure difference is at least about 2bar, and the pressure difference of 2kg requires more than 15% of electricity charge;

2. Permanent magnet frequency conversion technology can realize no unloading. Generally, ordinary compressors will have pressure fluctuation unloading. This part can be saved and generally accounts for about 13% to 15% of the total energy consumption;

3. Permanent magnet frequency conversion technology has no starting impact on the power grid, saving part of power consumption;

4, water lubrication oil-free screw machine almost no displacement attenuation can save part of the power consumption;

to sum up, it is theoretically calculated that the water-lubricated oil-free screw machine saves more than 30% of electricity compared with the oil-free piston air compressor. We calculate according to the actual electricity saving of 15%, running 24 hours a day and working 300 days a year: 15% X132X24X300 = 142560KWH

the composite rotor is designed for oil-free lubrication, good mechanical strength and wear resistance, so there is no need for speed increasing gears. According to the theory of fluid dynamic pressure lubrication professional design, pure water lubrication, the system without any oil or grease.

Replacing oil with water to achieve the four major effects of lubrication, cooling, sealing and noise reduction, providing high-quality 100% oil-free air, no pollution, no special treatment for discharged water, and meeting environmental protection requirements.

atmospheric and beautiful shell, food grade stainless steel material, safety, health, adapt to various occasions.

High efficiency water separator

food grade stainless steel shell, safety and health; Built-in liquid level measuring point, automatic drainage, water shortage alarm; No filter design, maintenance free.

Water filter

pressure resistance, large flow rate; Filter fine particles exceeding 10um; Disassembly and replacement of filter elements are convenient and quick;

water pump

ensure that in the start-up phase, when the suction and exhaust pressure difference is not established, forced water supply to the bearing and rotor cavity;

(Note: The water pump is used as an auxiliary equipment, only used in the startup phase, start ~ 15S before starting)

high efficiency and energy saving, no oil and gas wisdom choice

granklin oil-free water lubricated single screw compressor, using pure water lubrication of drinking water standard, the entire compression process without oil participation, can provide 100 high-quality oil-free air, is the first choice for the industry that needs high-quality compressed air.

Pure environmental protection: water lubricated pure oil-free compressor adopts pure water lubrication of drinking water standard. The whole compression process is oil-free and provides 100 oil-free air. It is the best choice for industries that need high-quality compressed air.

High efficiency and energy saving: due to the effect of water, the compression process is close to the ideal isothermal compression, and the air volume per kilowatt is 15% higher than that of the general dry oil-free compressor.

Excellent performance: Granklin water lubricated air compressor host and parts are made of composite stainless steel, with excellent corrosion resistance.

Patented technology: the use of patented sealing technology, to overcome the low viscosity of water, to solve the meshing gap seal, higher improve the efficiency of the whole machine.

Save money and worry, easy maintenance and worry-free

water lubricated air compressor maintenance content is very simple and easy to operate:

replacement of circulating water: after long-term operation, on the one hand, dust and fine particles enter the system; on the other hand, the acid or alkaline substances mixed into the water cause the pH value of the water to change. Although the main material and pipeline use acid-resistant stainless steel, acid or alkali is still unfavorable to the safe operation of the equipment. The water change period is set in the maintenance parameters, and the water-lubricated air compressor of Grankering will automatically change the water for the air compressor head;

replace the water filter: the dirt inside the system attached to the water filter will increase the resistance of the filter, which will lead to insufficient circulating water and cause burning. All machines are provided with differential pressure protection on the water filter. When the filter is dirty and blocked, the differential pressure on both sides increases to trigger an alarm. Users can replace or clean the filter element according to the alarm prompt on the maintenance interface.

Replacement of suction filter: routine maintenance content, users can replace or clean the filter element according to the alarm prompt of the maintenance interface.

Replacement of bearings: The water-lubricated host uses water-lubricated bearings, which are non-contact dynamic and static mixed bearings, so the theoretical design life exceeds 80000 hours. However, internal wear, start and stop, and the entry of debris will cause different degrees of damage to the host bearings. Therefore, regular maintenance is also necessary. It is recommended to disassemble and inspect the main engine bearing every 2 years, repair or clean the dynamic and static thrust bearing once, maintain the thrust bearing every 5 years, replace the thrust bearing, and conduct deep flushing of the shell and water channel.

    How to choose the medical grade oil-free screw air compressor

    There are not many brands to choose from for medical-grade air compressors. The water-lubricated air compressors produced by Shanghai Granklin Group are oil-free screw air compressors that meet medical conditions. In the medical and pharmaceutical fields, the gas compressed by the air compressor cannot contain oil and gas. The traditional oil injection screw air compressor cannot meet this requirement in any case. The traditional oil injection screw air compressor uses lubricating oil to lubricate the air compressor head from the structure of the air compressor head. It is impossible to do this step from congenital conditions, and the gas does not contain oil.
