Energy storage and pressurizing type hydraulic station

Abstract

The invention discloses an energy storage and pressurizing type hydraulic station. The energy storage and pressurizing type hydraulic station is used for providing stable and sufficient power for large-tonnage steel pipe extrusion equipment. The energy storage and pressurizing type hydraulic station comprises an oil tank, an oil pump motor set, an energy accumulator set, a pressurizer set, a control mechanism and a hydraulic pipeline, wherein the oil tank, the oil pump motor set, the energy accumulator set and the pressurizer set are connected through the hydraulic pipeline, an oil circuit inlet of the oil pump motor set is communicated with the oil tank, an oil circuit outlet of the oil pump motor set is communicated with the energy accumulator set, the energy accumulator set is composed of a set of energy accumulator units which are mutually connected in parallel, the pressurizer set is arranged behind the energy accumulator set and is connected with the energy accumulator set, the pressurizer set comprises two sets of pressurizer units which are connected in parallel, and each pressurizer unit is provided with two pressurizers. The energy storage and pressurizing type hydraulic station has the advantages that the arrangement is compact, the occupied area is small, the power requirements of the large-tonnage steel pipe extrusion equipment are met, the energy utilization rate is improved, and cost of steel pipe products is reduced.

Description

technical field [0001] The invention relates to a hydraulic station, in particular to an energy storage pressurized hydraulic station providing power for a large-tonnage press, and belongs to the field of hydraulic technology. Background technique [0002] As we all know, hydraulic equipment uses liquid pressure as the power to drive the action of the actuator to realize its function. At present, some large-scale steel pipe production enterprises use the extrusion molding process to produce large-diameter seamless steel pipes. Therefore, large-tonnage steel pipe extrusion production equipment has come out one after another, and at the same time, high requirements have been put forward for the hydraulic system of the steel pipe extrusion production equipment. [0003] The hydraulic system of the steel pipe extrusion production equipment is usually connected with the hydraulic station. The hydraulic station generally includes the driving mechanism, the executive mechanism, ...

AI Technical Summary

Problems solved by technology

Since the existing hydraulic station does not use the accumulator and supercharger together, and both are in low-pressure working state, the power of the steel pipe extrusion production equipment is mainly provided by the oil pump motor unit, in order to match the large-tonnage steel pipe extrusion production equipment , it is necessary to increase the number of oil pump motor units, which will not only bring about the problems of large system size and high energy consumption, but also lead to defects such as system vibration and unstable pressure, which will affect the normal operation of the entire system
