a vacuum pump (Mechanics), also known as booster pump, which is the braking system and the steering system booster. Creating a vacuum pump is used. The cars are generally hydraulic power brakes, truck or bus is usually steam-driven power brakes. Vacuum pump generates a negative pressure action is to increase the braking force. Vacuum pumps are generally automobile generator, i.e. a generator with a core shaft vacuum pump is rotating together, through continuous suction, pumping, the vacuum pump generating a negative pressure is off, i.e. in vacuo. The main parameters
1. The vacuum pump is
1, the degree of vacuum at different speeds.
2, different speeds exhaust time.
3, different speeds and hydraulic oil temperature.
4, the degree of vacuum in the vacuum tank volume reduction value 0 when the speed main parameters according to the above, may be employed as some of the tachometer, barometer, manometer, a stopwatch, a thermometer, and other measurements.
2. Routine maintenance pump
1. Manually rotate without loosening check vacuum pump and tubing junction, and proved a vacuum pump is flexible.
2. Add to the bearing body bearing lubrication oil, the oil level should be observed at the centerline of the subject in an oil, the lubricating oil should be replaced or supplemented.
3. Remove the water pump to the vacuum pump plug, filling water or lead paste.
4. Close the valve outlet pipe and the outlet passage and the inlet vacuum gauge table.
The move the motor, the steering motor and proved correct.
6. The start motor, when the normal operation of the vacuum pump, the vacuum pump inlet and outlet pressure gauge opening, depending on which exhibit the appropriate pressure, gradually open the valve, and check the motor load conditions.
7. try to control the pump flow and head on the plate indicated range to ensure the operation of the vacuum pump at the maximum efficiency point, to achieve maximum energy savings.
8. During pump operation, the bearing temperature does not exceed the ambient temperature 35 ℃, the maximum temperature not exceed 80 ℃.
9. found abnormal noise vacuum pump should stop immediately check the reason. When
10. The use of a vacuum pump to stop, turn off valve, pressure gauge, and stop the motor.
11. The vacuum within the first month of work, replacement of oil over 100 hours, after every 500 hours, the oil change once.
12. The packing gland regularly adjusted to ensure normal filler drip chamber to drip into the appropriate ..
13. The periodic inspection sleeveWear, should be replaced after wear large.
14 winter season use, after stopping, the need to pump a lower drain plug unscrew the media put the net. In order to prevent cracking.
15. Stop long term use, the need to pump all apart, dry water, the rotating parts and junction coated with grease installed, safekeeping.
