Embodiment Construction
[0021] In order to further disclose the technical solutions of the present invention, the following will be described in detail through examples in conjunction with the accompanying drawings:
[0022] A method for converting and reusing gravitational potential energy, characterized in that it is realized based on a gravitational potential energy conversion pipeline of a device for converting and reusing gravitational potential energy: when the piston of the hydraulic cylinder 10 of the lifting device goes down and there is a certain When the load F is heavy, the hydraulic oil in the hydraulic cylinder 10 of the lifting equipment extends out of the cavity and enters the oil port of the piston accumulator group 7 through the upper positions of the two-position three-way reversing valves 1 and 2 and the check valve 3. The two-position three-way reversing valve 4 is in the lower position, the two-position three-way reversing valve 17 is in the right position, both are in a closed s...

The device comprises a two-position three-way reversing valve, a one-way valve, a pressurizing cylinder set,a pressurizing cylinder set inner two-position four-way reversing valve, a piston type energy storage device set, a stop valve, an auxiliary gas bottle set, a lifting device hydraulic cylinder, an overflow valve, a motor oil pump set, an oil tank a and an oil tank b and is characterized in that an extension cavity oil port of the lifting device hydraulic cylinder is in series connection with thetwo-position three-way reversing valve and the one-way valve, is in parallel connection with the piston type energy storage device set, and is in series connection with the two-position three-way valve through loops in sequence, a gas port of the piston type energy storage device set is in series connection with the auxiliary gas bottle set, and is in parallel connection with the pressurizing cylinder set inner two-position four-way reversing valve, pressurized hydraulic oil flows into a main system oil path through the one-way valve via the pressurizing pipeline, and participates in extendingout of a piston rod of the lifting device hydraulic cylinder again, and an oil port of the parallel-connection piston type energy storage device set is connected to the connection joint of an outletof the one-way valve, an inlet of the two-position three-way reversing valve and an outlet of the two-position three-way reversing valve.
Description
technical field [0001] The invention relates to the field of energy recovery and reuse in the process of lowering hydraulic lifting equipment with load, in particular to a device and method for transforming and reusing gravitational potential energy. Background technique [0002] Among the hydraulic lifting equipment in oil and gas fields, the hydraulic energy storage workover rig has gradually been recognized by the oil field as a new type of workover rig for energy saving and emission reduction. For example, the patent No. 91106336.6 hydraulic energy storage The concept of energy storage, which converts the gravitational potential energy in the process of drilling into hydraulic energy for reuse, has never been realized. The so-called hydraulic energy storage is only a set of energy storage systems connected in parallel with the main system to complete the drilling process and other energy storage systems. The storage of pump output energy in the auxiliary time period has ...
