Hitachi, Japan imported 10 1001FH4 central air conditioning refrigeration compressors

Directly driven by the motor of the compressor, the crankshaft rotational motion generated to drive the piston rod reciprocate, causing the cylinder volume changes. Due to changes in cylinder pressure, through the air intake valve through the air cleaner (silencer) into the cylinder, the compression stroke, since the cylinder volume is reduced, the role of compressed air through the exhaust valve, the exhaust pipe, the one-way valve (check valve) into the tank, when the exhaust pressure rated pressure 0.7MPa pressure switch control and automatic shutdown. When the tank pressure drops 0.5--0.6MPa pressure switch automatically joins start. ? Hitachi compressor types? Many types of Hitachi compressor, according to the principle can be divided into displacement compressors, reciprocating compressors, centrifugal compressors, positive displacement compressor works is the volume of compressed gas, the unit the volume of the gas molecule density is increased to increase the pressure of compressed air; centrifugal compressor works is to improve the speed of movement of the gas molecules, gas molecules with a kinetic energy into pressure energy of the gas, thereby increasing the pressure of the compressed air. Reciprocating compressors (also known as piston compressor) works directly compressed gas, when the gas pressure reaches a certain discharge. Now commonly used Hitachi Hitachi compressor piston compressors, screw compressors Hitachi, Hitachi screw compressor is divided into twin-screw compressors and single screw Hitachi Hitachi compressor) centrifugal compressor and rotary vane compressor Hitachi, Hitachi scroll compressor. The following are definitions of various compressors. Cam, diaphragm and diffusion pumps and other compressor is not included, because it uses a special and relatively small size. Displacement compressors - directly dependent on changes in the volume of gas to improve gas pressure compressors. Reciprocating compressors - displacement compressors, the compression element is a piston reciprocates within the cylinder. Rotary compressor - positive displacement compressors, by the forcible movement of the rotating element implemented vane compressors - rotary variable displacement compressor, the axial vane on the same cylinder block for eccentric rotor radial sliding. Interception is compressed between the exhaust air vane in. Liquid - piston centrifugal compressor - belongs speed compressor, which has one or more rotating impellers (blades usually on the side) of the gas to accelerate. Primary air flow is radial axial compressor - belong to a speed-type compressor in which gas is accelerated by the rotor blades installed. The main gas stream is mixed axial-flow compressor - also belong to a speed-type compressor, the shape of the rotor combines both centrifugal and axial flow of some of the features. Jet compressor - the use of high-speed jet stream of gas or vapor inhalation of gas away, and then the diffuser will speed the gas mixture into a pressure. Guangzhou Hitachi refrigeration compressor manufacturers? Lower compressor running up the oil, compressor oil level should be maintained between the minimum and maximum oil level, oil and more will affect the separation efficiency, less oil will affect the performance of the machine lubrication and cooling oil change cycle, if the oil level is below the minimum oil level should replenish oil, is to release the internal pressure ① complete shut-down (to confirm system without pressure) off the main power switch. ② Open the fuel filler on the gas separation tank, add the right amount of cooling lubricants. ③ Hitachi compressor normal oil change after running see periodic maintenance table. Choose Hitachi compressor 1. Select the compressor basic principle is economy, reliability and safety. 2. The higher the pressure, the greater the power consumption. We shall consider the stress caused by the pipe diameter and length size reduction, coupled with pressure both for the lower limit of the pressure. 3. List the various models of the use of pressure, such as using too much pressure difference, the pressure of the air compressor shall purchase or use different booster, can not reduce the pressure to use, to minimize electricity costs. 4. Displacement is one of the main parameters of the air compressor, air volume selection, should take into account the gas cycle, the maximum amount of wind tip, storage capacity, may the leak and future expansion plans and other factors. Select the gas compressor and the required displacement to match, generally leave 10% -20% margin. If large gas consumption and small displacement compressor, pneumatic tools a start, will result in significantly lower compressor discharge pressure, and can not drive pneumatic tools. Of course, the blind pursuit of large displacement is also wrong because the larger displacement compressor with a motor greater, not only high prices, but also a waste of money to purchase, will be a waste of electrical energy use. Air quality and requirements of compressed air contains a lot of water, for precision instruments, pneumatic tools, pneumatic equipment, valve, instrumentation, piping, etc., causing great harm, because moisture can cause corrosion repair, clogged equipment, reduce the quality of the finished product, damaged equipment and lost a lot of money in repair maintenance, so the installation of clean compressed air compression system is really necessary.
