Open operation, matters needing attention of water ring vacuum pump _

now many manufacturers of cutting machine will be equipped with a vacuum pump according to customer requirements, fixed plate for the convenience of customers, attention but using a vacuum pump, but there is no clear told consumers, lead to many customers in the vacuum pump failure time is not sure what went wrong, today our common problems of water ring vacuum pumps do a simple explanation.

water ring vacuum pump main components are the following:

1, inspiratory mouth: adsorption pipe connection woodworking engraving machine.

2, dust hood: prevent wood shavings and other debris into the pump.

3, the check valve: when stop, to prevent the backflow of the water in the pump to the device.

4, feed line: to infuse working liquid pump and vacuum equipment.

5, inlet valve, control the flow of working fluid, boot must be fully open before the valve, and to ensure that water has entered the pump, to start the vacuum pump.

6, drain: the device USES 10 days or so, emptying the working liquid tank, replace the demineralized water clean.

7, vent: in the process of adsorption of gases, the atmosphere through the vent port, vent blockages, not more than two meters of line, not less than 5 cm in diameter pipe, otherwise easy to overload and damage the motor.

8, on water, add water to the tank, until the water mouth to drip water on, and in a day before you start the vacuum pump water regularly, ensure water tank has enough working liquid.

9, water tank, working liquid.

so we should pay attention to what problem before water ring used?

special remind: every time open the vacuum pump, must ensure that the vacuum pump with working fluid inside! Liquid level and work to achieve motor shaft above!

a: inspiratory mouth and carving machine adsorption pipe connection, strictly to seal and prevent leakage.

two: first, with all the screwdriver motor fan, make sure that the impeller no card lag phenomenon.

3: connect the motor power, and adjust the direction consistent with the standard operation.

4: fill the tank, it was in the mouth water drips water.

5: water injection valve in the open to the water pump, and wait for three minutes, to ensure the working liquid flow into the pump.

6: start the motor, vacuum pump to start working, adsorption mesa adsorption effect. Test the adsorption dynamics.

7: installation of motor overload protector, prevent motor overload burned! ! ! ! ( Pay special attention to)

water ring vacuum pump common problems and processing methods:

1, vacuum pump, vacuum.

the main reason: the working fluid entering the pump cavity, no formation water ring or suction pipe leaks.

2, water ring vacuum pump to start for the first time the motor does not turn.

the main reason: because of the impeller and the disk space is very small, oxidation of cast iron parts, new impeller jammed phenomenon, after the main solution to open the motor fan cover, taps the motor back axle head with a hammer, then turn the motor by hand wind leaf, determine after rotation, back to the fan cover, start the motor.

3, water ring vacuum pump suction.

main reason for the working liquid enough to enter, check the feed line way; Suction pipeline leak, check the suction pipe sealing performance. Long time did not change the working liquid, working liquid into a lot of wood dust, affect the quality of working liquid and so we must keep the working liquid for clean water.

4, water ring vacuum pump noise.

all main reason for the suction pipe caused by the vacuum pump suction valve is closed to the limit, the cavitation noise, open the valve inlet pipe road noise will disappear.

water ring vacuum pump maintenance and maintenance:

water ring vacuum pump in use process if it is found that the suction is insufficient, the motor sound is lighter, please stop the machine immediately to check

1, patient, check whether the water tank is more than two thirds vacuum pump pump head height position, if is too low please add water immediately.

2, if the water tank water level high enough, please check the water tank pump head between the intake pipe blockage caused by insufficient water supply.

3, equipment cleaning filling water, after the completion of work boot sure to block the air intake, control the volume to give enough water flow into the pump body, produce enough vacuum degree.

4, water ring vacuum pump, please be sure to use 150 days of clear water tank, water inlet pipe and in water. Short term does not use please close water tank inlet valve and emptying the inside of the inlet pipe of water. Long time not use, please complete control inside the pipe and pump head of the water, in case of rust, affect the operation.

5, do not use for a long time, if discovered after electric motor does not run, it is recommended to use tongs strength after rotating fan blade shaft, rust is loose, the pump head can normal use.

water pump is a good way to humanize JT and engage your target customers.
