Structure of Hertz Screw Air Compressor

Engine parts of the machine

• The engine is the soul of a screw air compressor. Including: compressor head assembly, electric motor, coupling set.
• The air compressor head (including motor, belt, gear, screw) helps to ensure the air compression of the screw air compressor.
• The screw includes 1 main shaft, 1 auxiliary shaft (1 big shaft and 1 small shaft) with teeth that coincide with each other.
• Electric motor and coupling help to convert electrical energy into mechanical energy. Most screw compressors use 3-phase motors.

Valve system of screw air compressor

• This is an indispensable part of any air compressor.
• The suction valve is responsible for regulating the flow of compressed air inlet.
• The one-way valve at the outlet helps the gas to move only in the predetermined direction from the beginning.
• The oil stop valve helps to prevent oil from spilling from the compressor head to the motor when the machine is not in operation. This valve is located at the bottom of the compressor head assembly.
• The minimum pressure valve (which functions almost like a check valve) helps to maintain a minimum pressure at the oil tank.
• The thermostatic valve helps to regulate the amount of oil.
• The solenoid valve performs the task of opening and closing.
• The safety valve helps to ensure that the machine is safe from incidents such as fire caused by the power source.

Lubricant related parts

• The oil return pipe helps to collect the oil at the bottom, helping to filter and separate the oil that remains after the oil separation process.
• The oil filter is installed between the oil tank and the screw to filter out dirt and impurities in the oil.
• The primary filter helps to minimize the impact of dirt and impurities inside the machine.

Cooling system of screw air compressor

• The cooling element is to help to reduce the temperature of the compressed air before it leaves the container.
• The cooling fan blows air around the oil and compressed air coolers.
• The temperature sensor helps to measure the machine temperature and gives warnings if the temperature is too high.
• An overload sensor (relay) is installed to protect the machine from electrical fires.
• The pressure sensor controls the machine to operate within the rated pressure range.
• In addition, the structure of the Hertz screw air compressor will have other parts such as switches, control screens, etc.

The working principle of the Hertz screw air compressor

The principle of screw air compressor is to change the air volume when the shaft rotates.

During operation, the two screws rotate, causing the clearance volume of the screw and the compression chamber to become smaller. This will create compressed air.

Working principle of oil screw air compressor

The oil and gas mixture is moved into the reservoir. Here, the process of oil screw air compressor will work as follows:

• Filter and separate the oil, push the oil back through the oil cooler to the air compressor and then continue the process.
• Compressed air goes through the oil separator filter, minimum pressure valve, air cooler, and output for equipment that needs to use compressed air.

Working principle of oil-free screw air compressor

Air line: Air through the inlet valve to Level 1 compressor to a pressure of 2 - 2.5 bar, Level 2 compressor intermediate radiator to 8 - 9 bar, Air radiator, Clean air outlet 100%.

Oil line: Oil tank, oil cooler, oil filter, lubricate the bearings of the compressor head, transmission gear, return to the oil tank to continue the next process.

Applications of Hertz Screw Compressors

Applications in the manufacturing industry:

• Create steam for spray guns mounted on robotic arms to spray paint samsung phone cases, paint metal surfaces such as marine paint.
• Compressed air is used to control the cutting of aluminum bars.
• To produce vacuum packaging to help prolong the shelf life of the product.

Application of air compressors in the maintenance of motorcycles, cars, and bicycles:

• Clean dry dust after washing motorbikes and cars.
• Coordinate with air intake gun to charge air for wheels...

Mining industry:

• Oil-free air compressors can provide compressed air containing oxygen to blow down mines for miners.
• Often used in conjunction with air tools such as air drills, etc.

Food and beverage industry:

• Used to clean containers and molds.
• Flow control of automatic production equipment, complete packing, filling, bottling.
• Fermentation of wines, beers, etc blows high-pressure vessels to create plastic bottles, plastic jars, etc.

Application of air compressors in transportation:

• Used in vehicle brake systems such as high-speed railways, trains, trams, subways, etc.
• Used in opening and closing the door of a train to adjust train tracks.

Advantages of Hertz Screw Air Compressors

• Produces a stream of high purity compressed air that can be up to 100% maximum. The generated oil gas is not mixed with oil, impurities, etc.
• Low maintenance cost of spare parts and periodic oil change of air compressor.
• No need to replace the overhaul compressor head, just replace the screw bearing set.
• Has a low and stable temperature level.
• The machine does not use a belt to drive, so it avoids limitations such as reducing working efficiency or using the machine suddenly due to the belt slipping or breaking.
• High performance, quiet due to compact, lightweight box design, does not take up installation space.
• The machine shell is made of soundproofing material, which helps the machine operate stably, limiting noise emission.
• The machine also has the ability to signal when there is a problem so that users can take timely measures.
