What is a lubricating oil pump? Brief introduction of lubricating oil pumps, mechanical lubricating systems generally use lubricating oil pumps to transport lubricating oil for machinery。 Lubricating oil pumps can be said to be an auxiliary device, and lubricating oil pumps are mainly used in the lubricating system of various mechanical equipment。 It is to transport lubricants。 Large-scale lubrication systems require the cooperation of two oil pumps, one AC oil pump and one DC oil pump, and their application methods are different。
Brief introduction of lubricating oil pump
Lubricating oil pump is mainly composed of pump body, gear, shaft, bearing, front cover and back cover, sealing components, coupling and other components. There are two types of shaft end seals: packing seals and mechanical seals. Principle: When the meshed gear rotates in the pump body, the gear teeth continuously enter and exit the mesh. As a result, the volume is increased and the lubricant is transported. The gear teeth enter and exit and mesh continuously, forming a continuous oil transfer process.
AC oil pump and DC oil pump
AC and DC lubricating oil pumps all play the role of lubricating machinery.
AC oil pump uses AC motor to drive the oil pump。 Some large equipment rotates too fast when starting, the main oil pump cannot supply lubricating oil, then the AC oil pump will turn on the lubricating oil supply。
Provide lubricating oil during startup, shutdown, accident, cranking。
The DC oil pump uses a DC motor to drive the oil pump.
When the electricity disappears, or the main oil pump fails, and the AC backup oil pump fails to start, the DC motor drives the mechanical lubrication oil. The DC oil pump is also called the backup oil pump.
What is a lubricating oil pump? The brief introduction of the lubricating oil pump is here。 AC and DC lubricating oil pumps are generally aimed at the same machine。 Interlocking, that is, when the AC power accident occurs, the DC oil pump is automatically put in to ensure mechanical lubrication。 Play a role in protecting machinery。
