Knowledge about the temperature of the water ring vacuum pump you know? _

Medium temperature of the water ring vacuum pump:

( 1) Water ring vacuum pump body is necessary to supplement cooling fluid,

to compensate for use with the gas discharge part of the liquid. Operation of operation temperature, generally between 0 ~ 40 ℃, 10 ℃ or below the boiling point. But in order to ensure the minimum operating fluid reach the best operation state, its temperature control should be in commonly 15 ℃ or so, such ability to reach the best effect of liquid ring vacuum pump.

( 2) Liquid liquid ring vacuum pump shaft seal liquid and task should be using the same medium,

this will shaft seal liquid recovery to the fluid of the job, job cuts liquid dosage, general shaft seal fluid flow control is 0. 5 dm3 /分钟。

( 3) Liquid ring pump medium smoke to lose by it is necessary to fully conform to the requirements of the product use,

liquid that is insoluble in homework, no corrosion and the pump body. General smoke transport medium temperature should be controlled in 0 ~ 80 ℃, thus we produce smoke to lose in the kiln temperature should be cooled to below 80 ℃ in advance, in order to reach the best effect.

( 4) Because vacuum pump transmission medium for the kiln gas,

containing CO2, CO and other poisonous substances, in order to ensure no leakage, cleaning, whether should always check the stuffing box in sealing fluid pressure, check the indicating value of the sealed fluid flow or pressure, regulating valve, to ensure the sealing liquid pressure is normal, in this particular case, should be selected with anticorrosive materials, such as 304, 316, 316 l stainless steel raw materials, etc.

the body temperature of the water ring vacuum pump: a reason analysis, water ring vacuum pump body temperature

1, water ring vacuum pump motor power, operating current is big, calorific value is big.

2, fan blade number is less, the air volume is small.

3, low fan speed, air pressure, air volume is small.

4 site bus voltage of 380 v, vacuum pump motor, because of the pressure drop of the cable and the uneven distribution of load, motor practice as long as the applied voltage 365 v, vacuum pump to run current voltage on the low side.

5, motor with dust, oil, can reduce the heat dissipation.

2, water ring vacuum pump temperature countermeasures

water ring vacuum pump motor power, rotational speed and vacuum pump matching, cannot be changed. Fan installed on the motor spindle, the fan speed motor speed resolution, also can't replace. Add fan blade number is can play will be effect, but after leaf number add, vacuum pump dynamic balance is not easy to find, if find is bad, can cause motor oscillation added.

1, vacuum pump, a former fan cover 40 cm long, inside with a diameter of axial flow fan with fan cover, axial flow fan motor power 850 w, the speed of 1489 r/min, voltage 380 v. The original fan last save. Axial flow fan all the way up the power control, the vacuum pump without chain of axial flow fan and the main motor. Vacuum pump launch axial flow fan in time after operation, vacuum pump shut down after 30 min suspended axial flow fan, in order to make the main motor and cooling;

2, remove the dust on the machine, vacuum pump time adhere to the motor heat sink clean, add the heat dissipation ability;

3, vacuum pump location changed busbar voltage to 400 v.
