Abstract
The invention relates to a rotary oil inlet device of an external lubricating oil station of a reciprocating vacuum pump, which solves the problem of dynamic and static conversion of oil inlet of the external lubricating oil station of the reciprocating vacuum pump through relative rotation between a shaft core and a fixed shell, has no lubricating oil leakage, is simple and convenient to disassemble, assemble and maintain, and ensures the long-term stable operation of the vacuum pump.
Description
Technical Field
The invention relates to an oil inlet device, in particular to a rotary oil inlet device of an external lubricating oil station of a reciprocating vacuum pump.
Background
At present, the well-known forced oil lubrication oil inlet mode of the reciprocating vacuum pump adopts an external lubrication oil station to supply oil, so that the full lubrication of a connecting rod big-end and small-end bearing bush and a slideway crosshead part can be ensured. When an oil supply pipeline of an external lubricating oil station is in butt joint with a rotating vacuum pump crankshaft runner, an oil inlet pipe is connected to an end cover fixed on a crankcase, and oil is fed through corresponding oil holes in the end cover and the crankshaft. Therefore, the crankshaft is radially communicated with the oil hole, two ends of the oil hole are sealed by sealing rings, and the sealing rings in a dynamic sealing state are easy to wear. And because the oil pressure near the oil hole is high, the oil leakage phenomenon at the end cover is inevitable, raw material waste and environmental pollution are caused, and the disassembly and the replacement of the sealing ring are troublesome.
Disclosure of Invention
In order to solve the defects in the prior art, the invention aims to provide an external lubricating oil station rotary oil inlet device for a reciprocating vacuum pump.
The technical scheme adopted by the invention is as follows:
the rotary oil inlet device of the external lubricating oil station of the reciprocating vacuum pump comprises a vacuum pump crankshaft, the external lubricating oil station and a conversion joint, wherein a lubricating oil channel is coaxially arranged in the vacuum pump crankshaft; the adapter comprises a fixed shell, a mandrel cavity and an oil inlet cavity are formed in the fixed shell, a hollow mandrel is coaxially mounted in the mandrel cavity, the hollow mandrel is movably supported in the mandrel cavity through two bearings, a composite sealing element is arranged between the hollow mandrel and the inner wall of the fixed shell, the head of the hollow mandrel extends out of the outer side of the fixed shell, the extending end of the hollow mandrel is mounted with a lubricating oil channel in a threaded connection, interference fit connection or flange connection mode, the tail of the hollow mandrel extends into the oil inlet cavity of the fixed shell, the oil inlet cavity is connected with an oil inlet joint, and the oil inlet joint is connected with an external lubricating oil station through a pipeline.
After the technical scheme is adopted, the invention has the beneficial effects that: through the relative rotation between the shaft core and the fixed shell, the problem of dynamic and static conversion of oil inlet of an external oil station of the reciprocating vacuum pump is solved, no lubricating oil is leaked, and the assembly, disassembly and maintenance are simple and easy. The long-term stable operation of the vacuum pump is ensured.
