pasture at present commonly used vacuum pump mainly has two kinds: rotary vane vacuum pump, roots vacuum pump. Today we have for the roots vacuum water pump.

roots vacuum pump

advantages: can be run long time operation, extraction ability, less maintenance, high reliability, no oil lubrication and seal ( Only need the gearbox oil) , no any pollution

weakness: the price is relatively high, the maintenance is more complex

applicable pastures: roots vacuum pump is heavy vacuum supply equipment, applied to large milking equipment

roots vacuum pump how to maintain?

every 500 hours need to be running maintenance work

a. Need to check the belt tension, no more than 6 mm, and the correction of vacuum pump and motor belt in a horizontal line.

b。 Check the gear box oil vacuum pump in liquid lens middle scale.

c。 End the roots vacuum pump bearing high temperature grease.

1 000 hours per run the need for maintenance work

a. Perform maintenance work 500 hours.

b。 Cleaning the roots vacuum pump pump head, had better be in front of the milk, use the heat generated by the vacuum pump operation to remove moisture, cleaning need 4 L water, alkaline or acidic cleaner need to 32 mL, rinse with water immediately after flushing, two consecutive alkali cleaning is generally use 1 time after acid cleaning.

c。 The test of the vacuum pump (containment In the vacuum degree of 50 kPa) And back pressure of vacuum pump ( No more than 5 kPa) 。

every 4000 hours need to be running maintenance work

a. Perform maintenance work 500 hours and 1000 hours.

b。 Replace lubricating oil pump head gear box, again add lubricating oil to the visual center of the liquid lens.

c。 Check belt situation, if necessary, replace and tighten belt, compression and tensile belt less than 6 mm.

roots vacuum pump common fault analysis extraction in

a. Wear in the join not correct lubricating oil pump, to pump damage. Need to change to add manufacturer recommended lubricating oil, roots vacuum water pump at work after a period of time temperature can reach 100 ℃ above, ordinary will be heated to steam and lubricating oil.

b。 The filter on the vacuum tank is too dirty or clogged, 1000 hours must be strictly implemented and maintenance, clean filter cotton.

c。 Increased wear of impeller clearance too much, resulting in the vacuum chamber, untight seal clearance through repair or replace worn parts for processing.

d。 Belt creep, tighten belt, compression and tensile less than 6 mm.

a pump abnormal vibration and noise. E. or bearing clearance than bearing wear. If the bearing clearance, replaceable bearing; If the bearing wear, replaceable end cover or replace the pump.

b。 Dust into the foreign body, or the roots vacuum pump, between the rotor and rotor and the pump shell inner wall. At this moment need to unpick and wash pump and oil change again.

c。 temperature too high. Processing method is: (1) check the oil in the pump is too dirty and too much, if too much oil drain to the visual center of the liquid lens, if it's too dirty oil change; (2) check whether filtering cotton or muffler jams, if the plug is clean; (3) improve the vacuum pump room ventilation.

d。 By changing the pump when end cover spill end cover gasket for processing.
