How to correctly use the dry screw vacuum pump -

( 1) Before all normal transportation and transport, should be run dry screw vacuum pump, check whether there are abnormal vibration and impact noise. The first use of dry screw vacuum pump should also be the limits of the gas pressure measurement of dry screw vacuum pump, it shall comply with technical standards. In the long run dry screw vacuum pump, under the standard of dry screw vacuum pump temperature above 70 degrees for it. Dry pumping speed measurement is very complicated. The general has not yet been check.

( 2) Dry screw vacuum pump is a kind of cooling circulating water equipment must be provided, before the start of cooling circulating water should be provided, and then restart. The import and export of cooling circulating water temperature is not suitable for more than 30 degrees.

( 3) Continuous stay dry screw vacuum pump and pump system software should be as short as possible and pipeline between the thick. Nominal diameter of the pipeline shall be the general. Dry dry screw vacuum pump inlet diameter should be very big, to prevent dry pipe friction endanger the speed of vacuum pump.

( 4) In order to keep working during the daily cleaning of the room, is conducive to the physical and mental health of the workers from the exhaust steam room immediately with hoses are out of the room.

( 5) Dry screw vacuum pump does not work or work for a long time at low temperature, will cause the start difficult. At this point, the air is dry screw vacuum pump vacuum pump should be introduced, mouth, dry screw vacuum pump should be in with a large number of spinning pulley ( Not connected to the switch power supply) Start after a few weeks. If the connection immediately dry screw vacuum pump, motor can run again a few times, will be stored in the lumen of the dry screw vacuum pump oil into the tank car, then start. If is bad, can immediately use dry screw vacuum water pump radiation sources or infrared heat lamp, until it can be moved.

( 6) Before using, check whether the vacuum pump oil of mechanical equipment to oil mark part of the window. In addition, make sure to check the direction of rotation of the motor pulley. Observer is opposite the pulley. Belt pulley should be clockwise. If rotating in the opposite direction, can change phase two connection end of the switch power supply. Otherwise, rotary vane vacuum pump will not produce the effect of pumping air into vacuum state, but the vacuum pump oil and air pump into the pumping system software, causing serious pollution.

( 7) After the completion of the work, first close the high vacuum valve, then close the low vacuum valve. And then stop the rotary vane vacuum pump, and then discharge air ( Such as electromagnetic induction with exhaust valve vacuum pump, to automatic exhaust valve) The ultrafiltration device to prevent oil return, finally disconnect main switching power supply and water supply.

( 8) Should be careful to prevent hard solid chemicals ( Metal particles, laminated glass, etc. ) 。 ) In order to avoid falling into the dry screw vacuum pump and scrape the dry screw vacuum pump is suitable for parts. Long downtime, dry screw vacuum pump should be stored in a dry clean natural environment, and vacuum pump and exhaust, so as not to waste into.

( 9) The mounting assembly line machinery and equipment dry screw vacuum pump, must be careful not to knock screw, highlight the surface or damage to the parts should be dry or air dry after cleaning, Temperature is unfavorable and exorbitant, time shoulds not be too long) 。 On the assembly line, dry screw vacuum pump, the walls painted with a small amount of vegetable oil to remove dead space space as much as possible. The remaining oil is based on the tubing, will pump out too much oil.
