The oil injection pump is the main component of the high-pressure oil injector. Each oil injection pump is fixed on the box with screws, the rotation of the camshaft pushes the lever to swing around the supporting pin. When the offset distance of the cam gradually decreases, the plunger moves downward under the effect of the spring, so that a vacuum is formed in the plunger sleeve of the pump body. Because of the effect of atmospheric pressure, the lubricating oil is sucked in the oil suction pipe. The lubricating oil sucked by the pneumatic high-pressure oil injection pump enters the oil drop pipe through the oil inlet pipe in the pump body. At this time, the oil cover is also in a vacuum state, the vacuum removes the oil the oil drop pipe. The oil is sucked out in the middle, the sucked oil enters the pump body the head through the small hole in the oil cover, so that a closed passage is formed in the oil cover.

Pneumatic high pressure oil injection pump equipment application method matters needing attention

1. This series of electric smooth pump should be installed in a place the ambient temperature is suitable, there is little dust, it is easy to adjust, check, repair, dismantle wash, is easy to replenish grease.

2. This series of electric smooth pumps should be placed in the center of the system as much as possible, shorten the length of the system piping, maintain the lowest pressure drop so that the pump can generate enough pressure to overcome the back pressure of the smooth point.

3. The set pressure of the pump pressure regulating valve can be adjusted arbitrarily within the range of 0-40MPa, it is allowed to exceed the nominal pressure of the pump (40MPa) during use.

4. The filter screen of the filter at the oil outlet of the pump should be cleaned regularly to prevent clogging.

5. If the pressure reaches about 50MPa due to some problem in the system, the safe sheet breaks, the reason must be found out cleaned before installing a new safe sheet.

6. To make up the smoothing agent in the oil reservoir, it is necessary to use an electric refueling pump the refueling port of the oil reservoir. It is strictly forbidden to pour butter directly after lifting the lid.

7. The membrane type capacity indicator in the oil reservoir is only suitable for smooth grease. When the medium is smooth oil, it is necessary to change to a float type capacity indicator.

8. It is necessary to make up the appropriate amount of 3# molybdenum disulfide grease the exhaust plug hole for the first two months of the electric reducer, make up every four months thereafter.

9. This series of electric smooth pumps are indoor installations, it is necessary to take protective measures when used outdoors in harsh environments.
