Our factory specializes in engraving machine water ring vacuum pump with a vacuum really a suction inlet pipe connection adsorption engraving machine, when the outer diameter of 47mm 2 stop valve to prevent water from the pump back to the apparatus; 3, dust mask to prevent sawdust and other debris from entering the pump; 4, into the water injected into the pump working fluid (water), the device creates a vacuum; 5, the inlet valve to control the flow of the working fluid, the valve must be fully opened before the turn, and to ensure that water has entered the pump inside, in order to start the vacuum pump; 6, drain the device about 10 days, emptying the working fluid inside the tank, clean replacement of demineralized water; 7, gas outlets produced in the adsorption process, through the exhaust port into the the atmosphere, the exhaust port can not be blocked, not more than two meters connected piping, tubing unacceptable diameter of less than 5cm, easy to overload, damage the motor; 8, water was added to the water level within the tank port, the port until the water level Tangshui far outside, and before you start each day with water pump timing, ensure adequate working fluid inside the tank. 9, the working fluid tank full bloom diagnose a problem, not a vacuum pump ,, main reasons: Not working fluid into the pump chamber, there is no leakage of water ring or suction line; 2, when the vacuum pump for the first time to start the motor does not turn, the main reason Primary cause: Due to the impeller and the disk space is very small parts to produce pig iron oxide, the term stuck impeller phenomenon, mainly back-end solution for open motor fan shroud, the rear axle with a hammer to tap the motor head, then rotate the motor by hand fan, determined rotation Replace the fan shroud, start the motor. 3, vacuum suction inadequate, mainly due to an insufficient amount of working fluid into and check the water pipes; suction line leaks occur, check the sealing performance of the suction line. Long working fluid is not replaced, the working fluid enters the large number of wood dust, affecting the quality of the working fluid, the working fluid must be kept as clean water. Use a suction port is connected to the pipeline adsorption engraving machine, strictly sealed to prevent leakage; 2, the initial start, struck with a screwdriver motor fan impeller to ensure no catching 3, connecting the motor power, and adjust the rotation direction and the Standard match; 4, into the water tank until the water level until Tangshui mouth; 5, open the valve to pump water, and wait for three minutes, to ensure that the working fluid flows into the pump 6, start the motor, pump start working, adsorption countertops produce adsorption effect. Our factory supply many models of wood engraving machine with water ring vacuum pump, there is 4KW, 5.5KW, 7.5KW, 11KW and many other types of vacuum pumps, vacuum pump selection 2BV series, simple and compact structure, convenient installation.
