Start and stop of SV Lyboa pump of ZJA insulating oil vacuum filter

2019/8/1??????view:

  Before starting the switch of SV Laibao pump, it is necessary to ensure that there is enough oil in the pump. The normal oil level is in the middle of the oil observation window.

  If you need to refuel, you need to screw down the filling plug and refuel, and then put the plug back in place.

  According to the design, SOGEVAC can be started at temperatures greater than 0 () according to the PNEUROP standard, depending on the type of oil used.

  In order to avoid motor overload, the number of starting pumps should not exceed 6 times in an hour.

  If frequent start-up is required, the pump should be continuously operated and connected to the vacuum vessel with a valve. In this case, the valve is used instead of starting/stopping the pump. When the valve is closed, the pump consumes little energy.

  Notes before starting oil filter pump:

  - Before starting the pump, ensure that the attachment of the connection meets your application technical requirements, so as to ensure safe and reliable operation.

  - Don't expose any part of your body in a vacuum. Because of the danger of injury. When the inlet is open, the pump shall not be started. When the pump is running, the vacuum joint, oil filling and oil discharge holes shall not be opened.

  - Safety regulations for special applications under different circumstances must be complied with. Especially in installation, operation and maintenance, waste disposal and transportation.

  1. Start and stop warnings

  Do not place your hand in the inhalation to see if it inhales.

  If part of the body is exposed to vacuum, the exposed part may bleed.

  Pre-start operation of SV Laibao pump for oil filter

  If SOGEVAC is equipped with an air ballast valve and has been opened, and the pump has reached its working temperature, it can extract air and steam.

  Contact LEYBOLD for important safety instructions before pumping out gases with oxygen content higher than atmospheric concentration and other highly reactive gases. When pumping oxygen, the pump must be degreased, modified and used with special inert oil.

  The motor manufacturer guarantees that the motor can be started up to six times per hour. In order to avoid starting more than 6 times per hour, the pump should be continuously operated and a guide valve should be used to regulate the vacuum of your system.

  2. Start and stop warnings

  Operating pumps are hot, and some surfaces can be as high as 80 (176) or above. Touching is dangerous for scalding. Please pay attention to the warning mark on the pump.

  Vacuum non-condensable gas

  If the process circuit mainly contains permanent gas and the temperature compression does not exceed the saturated vapor pressure during operation, SOGEVAC can be operated in an air-free ballast.

  If you do not know the composition of the air to be pumped and can not eliminate the possibility of gas condensation, you should operate the pump in accordance with Section 2.5.2 when the ballast valve is opened.

  Vacuum can condense gas and steam. Use gas town.

  The pump with air ballast valve is in the open state when it is delivered.

  3. Start and Stop Attention:

  SOGEVAC SV200 and SV300 can be equipped with three types of gas towns.

  Standard Gas Town (Product No. 95129)

  (The original product number is 10927, 95027, 95527, 10931, 95031, 95537).

  Gas ballast valve is the most closely related component to application. It determines the allowable partial pressure of water vapor.

  30 MABR at 50Hz

  40mbar at 60Hz

  As a model or accessories (product number 951-30), the "large flow" gas town (10% of the pump flow rate).

  This component is suitable for applications where there are more condensable gases entering the pump. It allows the water vapor tolerance to be higher than 50 mbar (the installation instructions are attached to this component).
