Product Description
Thank you for you interest in our pumps, follow is brief introduction of this prodcut,welcome to contact us for any other technical information or latest price.1. Brief introduction of Marine Twin Screw Air Compressor The screw air compressor is an air compressor which is a volumetric gas compression machine with working volume for rotary motion. The compression of gas depends on the change of volume, and the change of volume is achieved by turning a pair of rotors of the compressor in the casing.
The screw compressor is composed of a pair of parallel, intermeshing negative and positive screws, which is the most widely used in rotary compressor. 2. Structural characteristics of Marine Twin Screw Air Compressor
The basic structure of the screw air compressor: in the compressor body, a pair of intermeshing spiral rotors are arranged in parallel, usually the rotor with a convex tooth outside the circle, called the Yang rotor or the sun screw. The rotor with a concave tooth in the circle is called a negative rotor or a negative screw. The General Yang rotor is connected with the original motive, and the last pair of bearings on the rotor rotated by the Yang rotor is axially positioned and the axial force in the compressor is subjected to the axial force. The cylindrical roller bearings at both ends of the rotor enable the rotor to be positioned in a radial direction and bear the radial force in the compressor. At the two ends of the compressor body, a certain shape and size hole is opened. One is for inhalation, the other is air inlet, and the other is called exhaust port.
SUCTION
The working process of the screw air compressor is analyzed in detail. When the rotor is rotated, the space of the tooth groove of the Yin and Yang rotor is the largest when it turns to the opening of the intake end wall. At this time, the space of the rotor tooth groove is connected with the air inlet, because the gas of the tooth groove in the exhaust is completely discharged, and the tooth groove is in a vacuum state when the exhaust gas is completed. When transferred to the intake port, the external gas is sucked into the groove of the Yin Yang rotor. When the gas is full of tooth grooves, the inlet end of the rotor is turned away from the air inlet of the casing, and the gas in the groove is closed.
COMPRESS
The compression process of the working process of the screw air compressor is analyzed in detail: when the Yin and Yang rotor is at the end of the suction, the tooth tip of the Yin and Yang rotor will be closed with the casing, and the gas is no longer outflow in the tooth groove. The meshing surface gradually moves to the exhaust end. The gap between the meshing surface and the exhaust port is gradually smaller, and the gas in the groove is increased by compression pressure.
DISCHARGE
The exhausting process of the working process of the screw air compressor is analyzed in detail: when the meshing end of the rotor is transferred to the exhaust port of the machine shell, the compressed gas begins to expel until the meshing surface of the tooth tip and the tooth groove is moved to the exhaust end. At this time, the space between the meshing surface of the Yin and Yang rotor and the exhaust port of the engine shell is 0, that is to complete the exhaust process. At the same time, the length of the groove between the meshing surface of the rotor and the air inlet of the casing reaches the longest, and the intake process is carried out again.3. The Main advantage of Marine Twin Screw Air Compressor
1. high reliability, less spare parts and no wearing parts, so it has reliable operation and long life. The design life of general screw machine heads is up to 30 years.
2. the operation and maintenance are convenient and the automation level is high. Operators need not undergo long time professional training to achieve unattended operation.
3., the power balance is good, and there is no unbalanced inertia force. The machine can work at high speed and smoothly without foundation.
4. strong adaptability, with the characteristics of forced gas transmission, volume flow is almost free from the influence of exhaust pressure, and can maintain high efficiency in a wide range of working conditions. In the case of no change in the compressor structure, it is suitable for a variety of working conditions, so it is easy to fix the batch production.
5. multi phase mixing, the rotor tooth surface between the actual clearance, so the liquid impact, can be compressed to liquid gas, containing dust gas, easy to polymerize gas and so on.
6. spool valve flow regulation, no need to reverse flow, can effectively reduce energy consumption.
The screw compressor is composed of a pair of parallel, intermeshing negative and positive screws, which is the most widely used in rotary compressor. There are two kinds of single screw and twin-screw, usually referred to as twin screw compressor.
