A multi-bearing lubrication system

Abstract

The invention relates to a lubricating system, in particular to a multi-bearing lubricating system. The system comprises a low-level oil tank, a high-level oil tank, a multiplex pump group, an electric adjustment valve, a ball valve, a unidirectional valve and a cooler, wherein the multiplex pump group comprises an oil supply pump and three oil extraction pumps; the oil supply pump extracts lubricating oil in the low-level oil tank and supplies the lubricating oil to three experimental bearings for lubrication; the outlet pressure of the oil supply pump is controlled by the electric adjustment valve arranged at an outlet bypass of the oil supply pump; the lubricating oil at the bypass of oil supply pump enters the high-level oil tank; oil inlets of the three oil extraction pumps are respectively connected with oil return cavities of the three experimental bearings, and also connected with the high-level oil tank; returned oil of the oil extraction pumps returns to the low-level oil tank after being cooled by the cooler; the position of the high-level oil tank is higher than that of the low-level oil tank; the high-level oil tank can be either used for returning oil of the bypass of the oil supply pump or used for sucking oil of all the oil extraction pumps. The multi-bearing lubricating system is reasonable in design, compact in structure, easy to operate and high in reliability.

Description

Technical field: [0001] The invention relates to a lubricating system, in particular to a multi-bearing lubricating system. Background technique: [0002] In general bearing lubrication systems, separate oil supply pumps and oil return pumps are often used for oil supply and oil return. When a certain bearing is not installed, the corresponding oil supply pump and oil return pump are suspended. For a multi-point lubrication system, more pump sets need to be arranged to lubricate bearings with different numbers of usage. At this time, the whole system is complicated, occupies a large space, and is not easy to use. If multiple pump sets are used, corresponding space can be saved. However, if a lubricating bearing is canceled and its oil injection pipe is correspondingly canceled, the oil supply to the bearing must be cancelled, otherwise the system pressure cannot be established, and the corresponding oil pump will continue to run because it is connected to other pump groups,...

Problems solved by technology

However, if a lubricating bearing is canceled and its oil injection pipe is canceled correspondingly, the oil supply to the bearing must be canceled, otherwise the system pressure cannot be established, and the corresponding oil well pump will continue to run because it is connected to other pump groups, resulting in air suction and heating. cause damage

At this time, the corresponding oil well pump needs to be disassembled, resulting in a large disassembly work.
