Water ring vacuum pump gas water separator features and form work _
from the air and the water ring vacuum pump discharge part of the water, into the gas water separator, water flow to the bottom of the separator, the gas is separated out, and through the separator exhaust pipes.
for water ring compressor, the separator is the necessary equipment. Its main role is to make the gas separating from the water from the pump exhaust pipes, and after the separation of gas to need to gas pressure equipment. In addition, some gas water separator is up to the effect of cooling water inside the pump supplied.
for water ring vacuum pump, don't gas water separator, however, if the liquid ring pump use to be recycled, In order to avoid waste, for example, have recovery value or harmful, poisonous liquid ring) , or in the case of no running water, replenish water and within the water pump case, it is necessary to install gas water separator, to supply water to the pump. In addition, the separator can also eliminate water ring vacuum pump running noise, so it is also called silencer.
vacuum pump with equipment and compressor with equipment, the difference between lies solely with the different gas water separator:( 1) Before the pressure of the gas water separator is equal to atmospheric pressure ( Exhaust pipe directly pass into the atmosphere) , the top of the separator is flat, so can make simple manufacturing process, which is the pressure inside the gas water separator is equal to the required a certain exhaust pressure, the top of the separator is spherical shape, so as to increase the strength of the gas under pressure.
( 2) Different water system
the overflow of the vacuum pump gas water separator system is common conduit. When the water level of the separator exceeds the level of the overflow pipe, water level in water through the pipe to maintain equipment, as well as gas water separator for the compressor. The overflow system for the float valve, inside the hollow float. When the water in the equipment more than float, float float upwards, with special screw axis, driven and bolt connection rocker rotate, the right end of the rocker is connected to the workstation at the end of the screw, the station the other end of the screw embedded into the groove of the sleeve. When down rocker rotate, the sleeve through the fixed screw rotation, on the outer periphery of the overflow switch to rotate. The hole connection of the overflow switch, which makes water flows along the overflow pipe through the hole tube. Then the water level is falling, float also fell. Rocker was driven to move in the opposite direction. Casing hole on gradually away from the overflow hole on the switch, until the water table has dropped down to the level below the float. Float in a horizontal position, the above two holes completely staggered isolation, the water separator to stop the overflow. Can be seen from the above works, even if the separator water level below the overflow pipe in the horizontal line, gas can't through the overflow system ( The overflow of the gas and water) Flow separator. Vacuum pump separator can make gas through) So that the pressure of the gas and the volume is not lost, that is the compressor needs to run.
in general, water ring vacuum pump gas water separator system has four forms:
( 1) Working fluid directly from gas water separator. This is a widely used form. When the supply water is water and gas is air, usually use this form. Sometimes, in order to observe water level before the beginning of the level gauge pump, the pump is usually used to connect the pump to the separator.
( 2) The pressure differential between the separator and pump suction pipe used to close the work cycle. Please note that the working fluid from the separator now from the pump suction pipe into the pump, is unlikely to pass the pipe into the pump. In order to lower the temperature of the working fluid, set up the cooler in the pipeline.
( 3) pressure method is used to make the working liquid for the closed cycle use. Because of the working fluid entering pipes from water ring vacuum pump and reduce performance, pump can work pressure to allow the fluid directly from the pump body or side cover into the water ring vacuum pump.
( 4) In order to recycle as much as possible to dissolve the gas in the working fluid, low pressure separator can be set beside the separator. Through the gas-liquid separation after working fluid separation, into the low pressure separator. Dissolved gas in the working fluid is released, and then from the suction line into the water ring vacuum pump. When the acetylene gas is pressed send, you can use this form.
gas water separator is equipped with water supply pipe, used to supply water to the water separator, and equipped with ball valve. Stuffing box water supply pipe is connected to the pipe.
at the front of the pump inlet pipe is equipped with a gate valve, used to adjust the volume or vacuum. In order to prevent the water in the pump under the pressure of stops on the exhaust pipe into the intake pipe, you can install the check valve.
when using compressor, in order to adjust the pressure of exhaust gas pipelines, gate valves can be installed on the exhaust gas water separator.
