Description

Emergency and safe oil supply device for oil pump of expansion machine system

Technical Field

The invention relates to the technical field of oil pump equipment, in particular to an emergency and safe oil supply device for an oil pump of an expansion machine system.

Background

The expander is a machine which obtains cold energy by utilizing the principle that mechanical work is output outwards when compressed gas is expanded and depressurized to reduce the temperature of the gas. Expanders are commonly used in cryogenic equipment. The expansion machines are divided into a piston expansion machine and a turbine expansion machine according to the motion form and structure. The piston expander is mainly suitable for medium and small high and medium pressure deep low temperature equipment with high pressure ratio and small flow.

The main power of the expansion machine comes from the output of an oil pump, and the oil pump is a light and compact pump and comprises three types of in-line type, distribution type and monomer type. The oil pump can be operated only by a power source, and a camshaft at the lower part of the oil pump is driven by a crankshaft gear of the engine.

When the oil pump breaks down, in the process of protecting the emergency stop of the expander, certain measures must be taken to continuously supply oil to the bearing for lubrication until the expander is safely stopped. The existing centrifugal compressor is mostly designed with a high-level oil groove or an energy storage oil cylinder. However, most of the existing high-level oil tanks are not provided with emergency oil supply devices: when the oil pump is in a fault shutdown process, the rotor shaft continues to operate at a high speed, a low-pressure area with lower pressure relative to the gear box body is easily formed at the top of the high-position oil groove along with the reduction of oil, and under the action of pressure difference, the oil in the high-position oil groove cannot smoothly flow to the bearing operating at the high speed by means of self weight to lubricate, so that the bearing is mechanically abraded.
