Low Pressure Screw Air Compressor─Permanent Magnet Frequency Conversion

Design scheme of low pressure screw air compressor

Your equipment only needs compressed air below 0.5Mpa and 0.4Mpa. Our energy-saving series of low-pressure screw compressors are your good choice! Choose 0.5Mpa, 0.4Mpa low-pressure screw compressors than 0.7-0.8M The pa screw compressor saves more than 30% of electricity!

If you buy a 0.7M pa machine, and the actual use pressure is 0.5M pa, its working process is usually like this: the screw host first compresses the air to 0.7M pa, and then reduces the pressure to 0.5 through a pressure reducing valve. Mpa is used. In other words, what you are using is 0.5M pa pressure, and what you bear is 0.7M pa power consumption. If your pressure is 0.4M pa, you will spend more money unjustly.

Energy-saving screw host

The main engine of Unicol low-pressure screw air compressor adopts a customized screw main engine. As a large-scale enterprise manufacturing screw heads, the products are affirmed by its excellent and unique design, precise manufacturing, and have been tested by the market. The main engine is designed and used. The life span is more than 300,000 hours.

The exhaust end of the main engine adopts a pair of cylindrical bearings, which bear evenly distributed load through line contact. Greatly extend the life of the main engine, and use SKF grade bearings. The coolant tank designed at the bearing of the main engine avoids friction at the moment of starting and further extends the life of the bearing.

◎The main engine adopts three seals, and the shaft seal with oil return hole is designed at the shaft extension to 100% prevent the leakage of lubricating oil. ◎Unique asymmetric profile one realizes the optimization of power, torque and sealing.

Structure layout

The cold and hot chambers are separated, and the heat dissipation effect of the whole machine is better, ensuring that all parts work in the cold chamber, and the life extension is guaranteed. Integrating machinery and electricity into one, the machine does not need a special foundation on site, and it is extremely convenient to transport and install. Low-noise design, fully enclosed detachable chassis, with flame-retardant sound-proof sponge inside, allowing you to have greater flexibility when considering the placement of air compressors.

Motor

Unicol air compressors are equipped with motors that are commissioned to be manufactured by a professional motor factory according to high-level requirements. Each motor is strictly tested before leaving the factory. The four-stage motor has the characteristics of low speed and high reliability.

The motor is equipped with heavy-duty SKF imported bearings. Grease filling ports are added to the bearing shells at both ends, which is convenient for maintenance and fully reflects the humanization of the design. The P55 protection level can effectively prevent dust and water from entering the motor and prolong the service life of the motor.

Humanized layout

The user-friendly installation structure and the ease of maintenance greatly save maintenance time. The cooler can be removed and washed through the replacement of small parts such as the movable ammonium chain cover door panel, the rotary oil-gas drum cover, and the oil-gas drum with O-ring. It ensures the safe use of customers and is convenient for maintenance and maintenance, and facilitates the cleaning of the machine.

Low pressure screw compressor

The working pressure of compressed air required by the textile, cement, chemical fiber, building materials, and glass industries is 3.5-4.5bar, which is achieved by using a 7-Bbar air compressor with a pressure valve. This air compressor is a great waste of energy.

Design the host independently. The internal pressure ratio guarantees the specific power, and the depressurization exhaust pressure resistance is higher, and the effect is higher. Instead of an air compressor with an exhaust pressure of 7-8bar, it can save energy by more than 30%.

The oil pump is used for forced lubrication, which has sufficient fuel injection volume under extremely low exhaust pressure and maintains the air-air mixture ratio. The motor and the host are directly connected 1:1, with a large rotor and low speed. Ensure the high performance of the machine.

Increase oil and gas separation equipment to ensure that the export oil content is ≤3ppm.

The heat dissipation area of the oil cooler is increased by more than 30% to ensure normal operation in summer without over-temperature.
