Engraving machine has a main vacuum pump power source vacuum pumps, vacuum check valve, liquid resistant silencer, solenoid valves, air switches, filters, circulating water tank, management and valves. Engraving machine dedicated pump system: 1, the intake port connection adsorption engraving machine pipeline, diameter 47mm; 2, dust valve prevents sawdust and other debris into the pump; 3, when the valve shut down to prevent backflow of water from the pump into the device; 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 must be completely open the valve before the power and ensure that the water has entered the pump to start a vacuum pump; 6, drain the device about 10 days, the working fluid within the empty tank, clean replacement of demineralized water; 7, vent gas produced in the adsorption process, into the atmosphere through the exhaust port, exhaust Do not block the mouth, can not take more than two meters of pipeline, unacceptable pipeline diameter of less than 5cm, easy to overload, damage the motor; 8, water was added to stop the water level inside the tank opening until the water level outside Tangshui far, Before starting the pump and the timing of water per day, to ensure adequate fluid tank; 9, the working fluid tank full bloom. Engraving machine dedicated vacuum pump vacuum using a new generation of energy efficient products, the volume of the pump is small, high vacuum, stable and reliable product performance, using water as the working medium, is covered by a pump, pump, impeller, disc, mechanical seal and motor and other components. Imports of mechanical seals as standard. Engraving machine dedicated 2BV series water ring vacuum pumps are widely used in machinery, petroleum, chemical, printing and dyeing, food, sugar, metallurgy, chemical fertilizer, electronics and other industries. Use 1, the intake port and engraving machine adsorption pipe connections, strictly sealed to prevent leakage. 2, the initial start, struck with a screwdriver electric fan, make sure that the impeller without catching. 3, connecting the motor power, and adjust the running direction of the standard match. 4, into the water tank until the water level in the mouth Tangshui so far. 5, open water valve to the pump and wait three minutes to ensure fluid traffic flow into the pump. 6, start the motor pump to work, produce adsorption adsorption countertops.

Special note: Each pump is turned on, we must ensure that there are water pumps! Above the level required to achieve the motor shaft!
