【 Weak current College 】 water ring vacuum pump works---Power By 【 China power house network 】
<br> I. purpose and scope of use <br> <br> SK series water ring vacuum pumps and compressors work for suction or pressure gases and other non-corrosive, insoluble in water, not containing solid particles of gas, so that in .the closed vessel forming vacuum or pressure in order to meet the specific process requirements of the device. Suction or pressure of the gas in a liquid containing small permitted. <br> <br> SK series water ring vacuum pumps and compressors are widely used in .machinery, petroleum, chemical, pharmaceutical, food, ceramics, sugar, printing and dyeing, metallurgy, environmental protection and electronic industries. <br> <br> Because in the course of their work, the class a compressed gas pump is in isothermal condition ., so the pressure or suction of flammable, explosive gas, no danger, so their broader application. <br> <br> The pump model description. For example: SK-122i2J <br> <br> SK is expressed as a water ring .vacuum pump; 12 represents the pump maximum suction capacity as 12m3/min (m / min) <br> <br> Working principle <br> <br> 3 eccentric impeller installed in the pump body 2, starting at the pump to be filled ., a certain degree of water as a liquid, when the impeller rotation direction according to diagram 3, the role of water affected by centrifugal force in the pump body wall form a closed ring rotates, the upper portion of the 5-ring and is tangent .to the inner surface of the water wheel, the lower portion of the inner surface of the top contact coincides with the leaves. At this point between the impeller hub and the water forms a crescent-shaped space, this space was divided into a number of .blade impeller and equal to the number of small cavities. If the upper part of the impeller 0 ° is the starting point, then the front impeller rotation 180 ° small cavity volume, by small size and and end cap of the suction port, its inner .space, where the gas was inhaled, when inspiratory time small cavity eventually also with the suction port isolation; when the impeller at 180 ° and 360 ° rotation, water ring inner surface gradually and hub near, small cavity by smaller, their space, gas .pressure rise above the exhaust pressure, when a small cavity and exhaust air, gas is discharged. <br> <br> Impeller rotation for a week, each of the blade space (small Chamber) suction and exhaust, some small working cavity, and .so forth, the pump is continuous suction or pressure gases. Because in the course of their work, and work to produce heat, will make the work of the water heating, water and gas at the same part is drained away, therefore, in the .work process, you must constantly to pump water to cool and add the consumption of water pump, meet the requirements of the pump. <br> <br> When the pump exhaust gas, no longer used in pump vent termination with separator (available he .produced a water tank and replace), exhaust gas and the water discharged into the separator, the gases emitted by the exhaust pipes, the water because of the role of gravity in separator and back to the mains supply to the pump. As the Director of .the working time, the operating liquid temperature will continue to rise, the need for steam separator to a certain amount of cold water (can use tap water), to reduce the temperature of working liquid, that pump up the required technical requirements and performance indicators .as when used for compressor, pump vent attached vehicle separator, automobile mixture into the separator after the automatic separation, gas from the exhaust pipe to required system and working fluid through emitting automatic overflow water switch, compressed gases, liquid is extremely easy to generate heat ., by the pump outlet discharge, temperature becomes higher, so the bottom of the separator that you want to continue to supply water to the hot-water supplement was released while cooling the working fluid temperature is not too high, thus ensuring compressor performance, meet .specifications, meet work requirements. <br> <br> III. structure description <br> <br> Pump the pump body, front and rear end cover, impeller, shaft, and other parts. Intake and exhaust pipes installed on end cap on .the park-up above the suction holes and vent and pump cavity connected impeller keyed to the shaft, eccentric and installed in the pump body. Total space from both ends of the pump and the pump body and Park up to adjust the cushion between the impeller .and the front and rear garden plate clearance between the bushing (SK-1.5/3/6) promoting the impeller to adjust, ensuring a uniform gap at both ends. While the above pump shaft SK-12 and impeller is an interference fit, this .gap identified by the front end position. SK-120 no collar remaining structure and SK-6/12/30/42/60/85. Impeller two face and the front and rear Park disk space determines the gas at the pump cavity by the .air intake and exhaust flow loss of size and ultimate pressure. <br> <br> Filler installed in both ends of the cover, seal water through the small hole in the cover into the filler, filler and enhance sealing cooling effect. Impeller formation water .ring the necessary supplementary water supply by water (tap water) pipes, water pipes with separator together circulating water. <br> <br> If sealing type mechanical seal, mechanical seal's installment in the cavity, fillers without packing, packing gland into mechanical seal .gland, the same structure as the rest. <br> Bearing fixed by Park nut on the shaft. In the end caps installed in your garden, Park on a ceiling, vent and a rubber ball. Rubber ball valve is used when the impeller blades .between the gas pressure is exhaust pressure in the exhaust gas emissions before the feed as a result of gas pressure and the consumption of power, lower power consumption. <br> <br> Fourth, the device description <br> <br> Series liquid .ring type vacuum pump and compressor system consists of vacuum pump (compressor), coupling, motor and separator and pipeline components. <br> <br> Vacuum pumps and compressors and soft drinks at the master's works as follows: gas by pipeline via the valve .into the vacuum pump or compressor, then the imported gas pipe into the separator, the separator from the exhaust pipe. When used as a compressor, the compressor discharge of soft drink mixtures separation in separator, the gas through the valve to the need for compressed .air systems, the water is left in the separator, the water in the steam and water separator with automatic switch for adjusting water spills, when the water level higher than the required level, the overtopping switches to open, the water from spilling water overflow; .when the water level below the required level, the overtopping switch is closed, the water level in steam and water separator, reach the required level. Vacuum pumpOr compressor within liquid supply by separator (you can also use tap water), the size, volume .of water supplied by the water supply pipe on valve to adjust. <br> <br> Gas suction and pressure differences between the system only has to do with the internal structure of the separator. Pumping gas, inspiratory pressure below atmospheric pressure, atmospheric pressure .is equal to the vent, separator only overflow pipes; pressure gas suction port to atmospheric pressure (also available as vacuum), exhaust pressure higher than an atmospheric pressure, in order to ensure the transportation of gas pressure, the water level in steam-water .separator by overtopping switches to control. <br> <br>.
