Single stage rotary vane vacuum pump

Single-stage rotary vane vacuum pump can work at any inlet pressure. Single-stage rotary vane vacuum pump has been widely used in vacuum packaging of food and vacuum suction forming of plastic industry. Paper conveying, vacuum fixture and vacuum attraction in printing industry

single-stage rotary vane vacuum pump introduction:

1. Single-stage rotary vane vacuum pumps are single-stage oil-sealed rotary vane vacuum pumps, which are the basic equipment for obtaining vacuum.

2. The suction port of single stage rotary vane vacuum pump is equipped with coarse filter with wire mesh. It can prevent solid particles from being sucked into the pump chamber. Effective oil and gas separation is installed in the oil separator.
Exhaust Transistor for Separation Effect. When the pump stops, the suction valve built in the suction port isolates the pump from the pumped system and prevents oil from returning to the pumped system. The pump is air cooled.

However. All pumps of single stage rotary vane vacuum pump are driven by direct motor through elastic coupling.

single-stage rotary vane vacuum pump application :

1. Single-stage rotary vane vacuum pump is suitable for vacuum extraction in closed system. Such as vacuum packaging, vacuum forming, vacuum attraction.

2. Inlet pressure range: 100Pa~10000Pa. Oil mist will be generated at the outlet of vacuum pump when working beyond this range. Working ring of single stage rotary vane vacuum pump

The ambient temperature and the temperature of the inhaled gas should be between 5 40 C.

3. Single-stage rotary vane vacuum pump can not pump water or other liquids. No explosive, flammable, excessive oxygen and corrosive gases can be removed.

4. Generally supplied motors are not explosion-proof. If explosion-proof or other special requirements are required, the motor must meet the relevant standards.

single stage rotary vane vacuum pump operation :

Single-stage rotary vane vacuum pump should be placed horizontally. Similar to the pump operation, almost no vibration is generally not fixed. There are metric screw holes on the bottom cushion block of single stage rotary vane vacuum pump to fix the pump. Do not push and pull the pump on the ground to avoid damaging the cushion block.

In order to ensure a good cooling of the single-stage rotary vane vacuum pump, the air inlet and outlet of the pump should be more than 30 cm away from the surrounding objects. For ease of maintenance,It is suggested to leave 0.4m gap in front of the intake and exhaust ports of single-stage rotary vane vacuum pump. A base with an oil disc can be installed for easy oil discharging.

Single-stage rotary vane vacuum pump delivers pumps without oil. After installation, the specified vacuum pump oil is slowly injected through the filling port to 3/4 of the height of the oil window.

Electrical connection of single stage rotary vane vacuum pump:

Electrical wiring of single-stage rotary vane vacuum pump must be carried out by professional electricians. Appropriate motor overload protection devices should be used.

Single-phase 220V50HZ vacuum pump must ensure that the voltage is in the range of 220V + 10%. If the voltage is lower than 220V, it must be equipped with AC voltage stabilization.
Device. Do not work under low and high voltage for a long time to avoid damaging the motor.

After the connection of three-phase asynchronous motor of single-stage rotary vane vacuum pump is completed, the direction of the motor must be checked. The correct rotation direction of the motor is as follows: from the fan end of the tail of the motor The rotation direction of the motor shaft is counterclockwise.

When checking the rotation direction of single-stage rotary vane vacuum pump, the suction port should be opened or completely covered with rubber sheet (over 4 mm thickness), and the power supply should be connected for 2-3 seconds.

If the rotation is correct, the defendant will feel strong suction in the suction port or the rubber sheet will hold tightly. If reversed, adjust any two of the three power lines.

System connection of single stage rotary vane vacuum pump:

The intake pipe of single stage rotary vane vacuum pump should be no less than the size of the suction port and as short as possible. Vacuum the threaded joints with Lotte 515 or Teflon tape Seal up.

Dust filters must be installed at the intake end of the pump if dust is contained in the exhausted gas. If necessary, the exhaust pipe should be inclined downward.

single stage rotary vane vacuum pump starting :

Start after determining oil level. After the second start and each change of wiring, the single stage rotary vane vacuum pump must be checked to start backward.

single-stage rotary vane vacuum pump operation:

Before normal operation, it is advisable to close the intake valve so that the pump can run for more than 15 minutes under the limit pressure condition, which can effectively remove the steam from the gas.

Steam. Motors should not be started frequently (less than 6 times per hour). It is recommended to install solenoid valves in the intake pipe of the pump during intermittent cycle operation and in the non-working stage.

Close the solenoid valve to make the pump work under the limit pressure, so that the motor consumes less power, but can effectively protect the vacuum pump.

single stage rotary vane vacuum pump limit pressure measurement :

The limit pressure of a single stage rotary vane vacuum pump should be measured directly by a compressed vacuum gauge at the suction port of the pump. Pump first use, long-term shelf after use, after the replacement of new oil

The air intake should be closed for at least 1 hour after operation, so that the single stage rotary vane vacuum pump can reach the working temperature and the limit pressure of the pump oil can be measured after fully degassing.

single-stage rotary vane vacuum pump maintenance :

Single-stage rotary vane vacuum pumps should generally use single-stage rotary vane vacuum pump oil in accordance with the SH0528-92 standard. The ambient temperature ranges from 10 ~40.

Single-stage rotary vane vacuum pump oil of ISO~VG100 viscosity grade. Vacuum pump oil of ISO~VG32 viscosity grade is used at ambient temperature of 0~10 ~C. Vacuum pump

The oil level must be guaranteed at 1/2-4/5 of the oil window height when running. Oil level and oil pollution should be checked regularly (once a week is recommended). Stop if oil level is too low

Single-stage rotary vane vacuum pump with suitable vacuum pump oil to oil window height of 4/5. If the oil is contaminated, it will become black, emulsified and thicker, and the oil should be changed in time.
