Practical documentation of training materials for screw compressors for 2005 1 the spiral compressor slides in less than one part, such as an action valve, which must be exchanged for a short period of time, and is therefore highly reliable and does not require major repairs for long periods of time. 2 the structure is simple and the number of main parts is approximately 1/10 (in-house). 3 double seal structure, low noise. 4 refrigerated compressors are low vibrations because they are compressed by continuous inhaling. 5 high efficiency, especially for cryogenic uses, air heat sources, and cooling and heating, can perform ultra-group performance. Capacity control is both phased and continuous and broadly adaptable to different needs. 7 if liquid refrigerant is injected on the side of the compressor, the temperature of the discharged gas will not rise to above 120°c. 8 special synthetic lubricating oils with an excretion temperature of 120°c and which are not carbonized or degraded. 9 compressor starts with a small load, and motor starts with a small star-triangular (λ-Δ).

Standard script document 1. 2 the working principle screw compressor compressor compressors compresses the pressure by reducing it by reducing it by reducing it by reducing it by reducing it by reducing it by reducing it by compressing it to the specified pressure by combining it with a rotor (hereinafter referred to as the m rotor) consisting of six cogs (hereinafter referred to as the f rotor). [inhalation process] inhalation of refrigerants from inhalation openings in the direction of the axis to the radius. As the rotor turns, on the lower side of the rotor, the rods are split open, the length of the gutter increases, and the refrigerant is inhaled into the tooth space. [compression process] from the inhal side of the gutter, the rods of the teeth begin, sealed, and the line gradually moves out of the side, the tooth space is reduced, and compresses. [compression process] by inhaling the lubricant along with the refrigerant, a membrane seal is formed within the mesh of the rotor, while the rotor is lubricated. The luminaries and the tumours are coming closer to the exits to compress, and the pressure is rising. Standard scripts practical documents sent out completely. Out of the process] the carving space is connected to the platoon exit, and the process begins. This process continues to the extremity end until the refrigerant in the tooth space is marked by the outer size and structure of the 1. 3 compressor 1 to 3 as the size and structure of the compressor. The rotor 2 in figure 3 is supported by a rolling column bearing 3 and the directional force generated by compressed cold coal is supported by a roller bearing bearing 6. The axle is 3 ~ 4 times greater than the axle convection, so that in order to ease the axle, the ball bearing on the side of the arc is used to increase load capacity. Capacity control is a slide valve that forms part of the shell. Moved through piston 9 towards the axis and controlled through cold coal by side. In addition, the standard specification for motor 4 hidden in the shell is 200 v λ-compression. Figure 3 is the breakdown of compressors. Please confirm the location of the parts through this chart.

As shown in figure 5, when zirconium is activated, zirconium's wires are wired using star-shaped (λ) wires to control the start-up current by adding one per cent to each power source, and when the motor accelerates into normal operation, switch to a triangle (Δ) connection to fill the power voltage. In this way, the start-up current can be controlled to a third of the total voltage only. Figure 4 λ - moda starter 1. 5 lubrication structure lubricating oil systems as shown in figure 5. Because the screw compressor is a structure that uses lubricant oil to be stored in a high pressure d shell, which slides to the oil supply through a high pressure and low pressure differential, it is not necessary to use the same oil pump as the back-up compressor. The oil stored in the d-hulls is filtered through 150 eye-scan oils, and is fed to three systems: 1-direction bearings (roll-axis bearings and roller bearings) for oil to be supplied to the lumbers and rotors, lubrication of the bearings, inhalation of the rotors, lubrication of the rodents, discharge with the chiller, separation through the separators and return to the d-hull storage. 2 to provide oil to rotor dents for inhalation of the side-roll bearings and the oil cycling in the cycle, to supply oil to the rotor radon unit, to excrete with the refrigerant, to be separated by separators and then returned to storage at the bottom of the d shell. The oil is supplied to the capacity control unit through a casket, which provides oil to the cylinder, drives the piston, discharges the oil to the inhaled side of the shell, is re-inhaled into the rotor, and then returns to the storage of the d shell as one. As noted above, the oil is supplied from the d-hull to the sliders, inhaled into the rotor, excreted with the refrigerant, separated by the separators, the standard file, then returned to the d-hull storage, while the refrigerant is excreted to the condenser. The capacity control unit for the volume control structure screw compressor, as shown in figures 6, 7 and 5, semi-confined screw compressor lubricant system chart (phase control) 1. 6 the effective inhalation is adjusted by sliding the slide valve in the direction of the rotor axis, as shown in figures 6, 7。once the gas is inhaled into the cone of the rotor, as the slider slides in the direction of discharge, the excess indicated by the dashed arrow will pass to the side of the inhalation, with only the necessary amount of gas discharged. The slide valves act by pressing the piston fixed on the slide valves. Figure 6 illustrates capacity control as an example of phase control. The slide valve is 100% load when moved to the leftmost side, whereas the minimum load is when moved to the rightmost side (405 su is 33% load, 505 su and 605 su is 25% load). The figure is 75 per cent load. The following indicates that the actions of the compressor electromagnetic valves are all shut down when 100% of them work. So the a-b side of the piston is all high pressure, but the a-side side of the slide valve is high pressure, the b-side is low pressure, so the slider is sliding to the left side and holding it at 100%2 load. Electromagnetic valves are opened at 75% of the load20, the side of the piston a is open to low pressure, and due to the pressure differentials on the side of the piston ab, the slide valve moves to the right and strikes a balance of pressure in the image position, fixed and operated at 75% of the load. In addition, the minimum offload necessary to reduce the start-up rectangular when the compressor starts is to turn off the electromagnetic valve 20, open the electromagnetic valve 20, open the a face to low pressure, and slide the slider to the right. The coil spring attached to pistol b is used to push the piston to the right at the end. Standard script practical documents comment: this chart is a view from above the compressor.
