The offshore platform hydraulic system is mainly used for opening and closing the cabin door and the hydraulic control valve, and provides a necessary hydraulic source for life saving equipment and other users in need. The existing hydraulic system has to start a hydraulic pump during working, so that the hydraulic pump is frequently started and stopped, the system bears too much hydraulic impact, and the service life of equipment is shortened. In addition, the response time of the device can be too long due to delays in the control system.
Disclosure of Invention
The utility model aims at solving the weak point that above-mentioned background art exists, and the novel energy storage hydraulic system of offshore platform who provides need not frequently open at the hydraulic pump and stops under the condition, realizes hydraulic oil user's quick response, reduces the impact to the electric wire netting.
In order to realize the above-mentioned purpose, the utility model discloses a novel energy storage hydraulic system of offshore platform, fill including hydraulic pressure and can the subassembly, its special character lies in, hydraulic pressure is filled can the subassembly and is included oil tank, hydraulic pump, high pressure filter and overflow valves, hydraulic pressure is filled can parallelly connected a plurality of hydraulic energy storage subassembly between subassembly and the hydraulic oil user, and each hydraulic energy storage subassembly includes piston accumulator and accumulator safety valves, and all hydraulic energy storage subassemblies pass through return oil filter and oil tank intercommunication.
Furthermore, the hydraulic energy charging assemblies are connected in parallel in the hydraulic pipeline, and one hydraulic energy charging assembly is used for one hydraulic energy charging assembly.
Furthermore, a pulsation attenuator is arranged in a pipeline connecting the hydraulic energy storage assembly and a hydraulic oil user.
Further, the hydraulic pump is communicated with the oil tank through a hose and a ball valve.
Furthermore, the number ratio of the hydraulic energy storage assemblies to hydraulic oil users is 1: 1-1: 8.
The hydraulic station has the main function of converting electric energy into hydraulic energy; the hydraulic energy storage system stores hydraulic energy and distributes energy through the hydraulic energy storage assembly, so that each energy storage device is in an operating state, and sufficient standby energy storage is ensured; the hydraulic energy storage assembly transmits energy to each user.
The utility model adopts the above technical scheme, have following advantage:
1. the passive pressure supply is carried out under the normal working condition, and the response is fast;
2. the energy storage system can be charged when the power load is small, so that the load of a power grid is reduced;
3. the hydraulic pump cannot be started or stopped frequently, so that the equipment loss is reduced, and the impact on a power grid is reduced;
4. a cooling circulation system need not be provided.
