Carbon Graphite Blades for Vacuum Pumps

Product Description:

We can specially manufacture carbon graphite blades in various sizes for oil-free vacuum pumps and compressors. As one of the core components of the pump, carbon blades have strict requirements in terms of material properties, mechanical dimensions, and shape and position tolerances. At the same time, as a vacuum pump manufacturer, the quality of carbon blades has been widely verified and recognized in the long-term use of vacuum pumps. We provide carbon blade matching for many domestic water pump manufacturers, distributors and users. We have exported pumps, parts and carbon vanes to more than 40 countries and regions.

How to get the carbon blade size you need?

1, Show the nameplate of the pump.
2. To measure, measure its length, width and thickness. But if you measure old blades, the width is not accurate because the blades have worn down to be shorter than the original. At this point you can measure the depth of the rotor slots to get the width of the blades.
3. Determine the number of each group: the number of rotor slots is the number of blades in each group.

Carbon sheet usage skills:
1. When using a new pump, pay attention to the direction of the motor, and do not connect it backwards. Prolonged reverse rotation of the pump can cause damage to the vanes.
2. The working environment of the pump is too dusty, and the air filtration is not thorough, which will accelerate the wear of the blades and reduce the service life of the blades.
3. Humid environment will cause corrosion of blade and rotor groove wall. When the air pump is started, the blade part cannot be thrown out, and the blade is damaged due to uneven force. In this case, check the blades first and clean them.
4. The use of the air pump, frequent switching will increase the number of throwing blades and reduce the life of the blades, which should be avoided as much as possible.
5. Inferior blades will lead to a decrease in the performance of the air pump or damage to the inner wall of the cylinder, so they should be avoided.

How to replace a new carbon blade:
Karen vane is a kind of consumable material, wear to a certain extent will affect the performance of the air pump and eventually break down. At that time you will have to replace the blades with new ones.
1. Before replacing new blades, clean the rotor groove, air pump cylinder wall, cooling pipe and filter air bag with compressed air.
2. Check whether the cylinder wall is worn (blades with too hard material will wear the cylinder wall). If the cylinder wall is damaged, the air pump will make noise when it is running, and the blades will be fragile.
3. When installing the blades, pay attention that the slope direction of the blades is consistent with the radian of the rotor groove (or make the low point and high point of the slideway width consistent with the low point and high point of the rotor groove depth). If the blade is installed upside down, the blade will seize and break.

4. After the blade is replaced, first unplug the connecting air pipe, start the air pump, discharge the residual graphite debris and dust in the air pump, and then take over the pipe for use.
