    4. Operation 4.1 Precautions on Operation Do not use any gas other than inability gas The pumping of toxic gas, flammable gas, combustible gas, corrosive gas, explosive gas and particle gas, may damage this pump and hazardous. Furthermore, the chemical reaction of remaining gases and/or generated particle and gases may cause the explosion, not only during operation but also after stop operation.
  • Page 52 Close the gas ballast valve before starting operation. Be sure to close the gas ballast valve before starting operation. In high pressure regions, oil may blow out from the gas ballast valve. Do not touch any place other than the valve during gas ballast operation.
  • Page 53 When exhausting a large amount of water etc., change oil frequently. When exhausting a gas containing a large amount of moisture etc., change oil frequently. When operating with a large amount of water mixed in oil, the ultimate pressure first increases and then the oil lubricity deteriorates. This may lead to failures such as oil leaks through oil seals, internal corrosion, breakage of exhaust plate, and seizure inside the pump.
  • Page 54 Take care not to allow foreign matter to mix. NOTES If the pump sucks solids, such as dust and fine powder, or water, not only the ultimate pressure gets worse but also it may cause a failure. The inside of the pump is designed to rotate with a slight clearance and, if foreign matter enters the pump, it may become unable to rotate.

  • Page 55: Preparation For Operation

    4.2 Preparation for Operation 4.2.1 Pre-operation check Before operating this pump, reconfirm the following. 1． Make sure that the cooling water piping and electric wiring connection are completed. 2． Check that the exhaust port is not blocked by a protective cap or storage flange. 3．...

    4.3 How to Startup/Stop 4.3.1 Startup To start this pump, follow the procedure below. 1． Close the vacuum valve and leak valve. 2． Turn on the power to the motor. 3． Check whether the pressure gauge between the vacuum valve and the pump indicates a pressure drop to around the ultimate pressure.

  • Page 57: Drain Of This Pump

    4.3.3 Drain of this pump Perform drain work when there is a risk of freezing or when this pump is not used for a long period of time. NOTES Drain water in this pump. Drain water in this pump. Accumulated water may cause a failure, such as rusting inside this pump and damage to the parts due to freezing.
  • Page 58 How to operating of gas ballast 1. Close the vacuum valve, leak valve, and gas ballast valve, and start operation. 2. After the pressure drops, introduce air or nitrogen from the gas ballast valve. 3. Continue operation for approx. 20 minutes to sufficiently increase the temperature of the machine. If a lot of moisture enters the pump at a time and cannot be processed, the moisture is built up at the bottom of the oil tank.

  • Page 59: Removal

    5. Removal Do not suck toxic gases into this pump. If toxic gases are sucked into this pump, not only this pump but also the oil becomes toxic. Take care during maintenance. Before installation or removal work, disconnect this pump from all energy sources.

  • Page 60: Removal Of Piping

    5.1 Removal of Piping 5.1.1 Cooling water piping Wait for the temperature of this pump to decrease. Immediately after operation is stopped, this pump is at a high temperature. Wait for a while until the temperature of this pump decreases and then remove and check the parts.

  • Page 61: Inlet/Exhaust Port Piping

    5.1.2 Inlet/exhaust port piping After the temperature of this pump decreases, remove the piping for the inlet/exhaust port.

  • Page 66: Inspection And Replacement Of Oil Mist Separator

    6.2.4 Inspection and replacement of oil mist separator This unit comes equipped with an oil mist separator as standard. The oil mist separator separates oil from the gas discharged from the pump. Severe clogging of the separator can prevent exhaust gas from passing through the filter, increasing the pressure inside the pump and causing the pump and oil mist separator to burst.
  • Page 67 Replacement of oil mist separator 1. Stop the pump. 2. Remove the red-circled cover of the oil mist separators. 3. Remove the two inner bolts. 4. Remove the oil mist separator support. After the support is removed, the filter can be removed. Take care not to drop or make an impact.

  • Page 68: Replacement Of Exhaust Valve Plate

    6.2.5 Replacement of exhaust valve plate Replace the exhaust valve plate every 8,000 hours. It may break early due to suction of foreign matter and water. ■ Replacement of Exhaust Valve Plate Stop the pump. 2. Remove the maintenance cover on the side of the pump. 3.
  • Page 69 Replace the exhaust valve plate and fix the exhaust valve guide. At this time, place all the exhaust valve plates to close the exhaust port first and then install the bolts. This prevents bolts and spring washers from dropping into the cylinder through the exhaust port. If any parts drop into the cylinder, an overhaul is required.

  • Page 70: Cleaning Of Oil Tank

    6.2.6 Cleaning of oil tank The sucked foreign matter, products, sludge of pump oil, etc. are accumulated inside the oil tank. If the amount of deposit increases, it cannot be removed only by changing oil, which may cause damage to the pump as the contaminated/degraded pump oil is used for lubrication.

  • Page 71: Inspection Of Automatic Drain Valve

    6.2.7 Inspection of automatic drain valve If the ultimate pressure does not drop from several hundred Pa or so, it can be a fault in the automatic drain valve. Monitor the ultimate pressure as daily inspection and, if the ultimate pressure does not decrease, make an inspection.
  • Page 72 5. Carefully wipe off any deposits. Take special care when wiping off the rubber seal part of the sealing section. 6. After wiping it off, install the automatic drain valve. Install in the direction that the float section moves upward as shown in the photo. At this time, take care not to scratch the O-ring. 7.

  • Page 73: Replacement Of Oil Filter

    6.2.8 Replacement of oil filter This pump comes equipped with an oil filter as standard. The oil filter removes impurities contained in oil that circulates in the pump. If the amount of oil circulation is reduced due to a clogged oil filter, it may cause failures such as rapid wear or seizing up of the parts.

  • Page 74: Maintenance And Cleaning Of Heat Exchanger

    5. Add the specified amount of oil into the pump from the oil filler port. Operate the pump and check whether or not the oil level is within the range of the oil gauge. 6. Install the other parts in reverse order. 6.2.9 Maintenance and cleaning of heat exchanger This unit uses cooling water to cool down oil circulating in the pump in a heat exchanger.

  • Page 75: Inspection After Long-Term Storage

    If this pump is stored for a long period of time without being operated (at least six months), trouble may occur when the pump is operated due to rusting. If the pump has not been used for a long period of time, request an inspection from your local ULVAC service center before using the pump.
