Problems solved by technology

Both kinds of leakage will cause the pressure of the air cavity to drop, so that the accumulator needs to be frequently inflated and replenished, which shortens the gas replenishment cycle, increases the cost of use, and reduces the reliability of the system, which affects the normal use of the piston accumulator

Abstract

The invention discloses a novel winding type energy accumulator. The accumulator comprises a cylinder body of the energy accumulator, a piston arranged in the cylinder body, a gas cover arranged abovethe cylinder body, and an end cover arranged below the cylinder body; the cylinder body is divided into an upper gas cavity and a lower oil cavity through the piston, the gas cover is provided with agas port communicating with the gas cavity, and the end cover is provided with an oil port communicating with the oil cavity; and the piston freely slides in the cylinder body under the action of pressure fluctuation of the oil cavity and the gas cavity, and initial pressure is derived from inert gas inflated into the gas cavity and having a predetermined pressure; and an upper locknut is arranged above the gas cover, the gas cover is connected with the upper portion of the cylinder body through the upper locknut, and an inflation valve is further arranged on the gas port. The energy accumulator is simple in structure, convenient to machine, good in sealing performance, free of process difficulties, convenient to install and set and capable of being popularized and used.

Description

technical field [0001] The invention relates to an accumulator, in particular to a novel wound accumulator. Background technique [0002] The piston accumulator is a commonly used isolated hydraulic capacity storage device in the hydraulic system. Its function is to stabilize the system pressure, and the second is to store the energy in the system and release it again when needed. Its working principle is: the piston separates the cylinder into two parts, the upper part is pre-filled with a certain pressure of gas, and the lower part communicates with the hydraulic oil circuit through the oil port. When the system oil pressure rises, the hydraulic oil pushes the piston upward to compress the gas, and the gas pressure rises. When the gas pressure is balanced with the system oil pressure, the piston stops moving, and the accumulator completes the liquid filling stage; when the system oil pressure decreases, The gas pressure is higher than the oil pressure, the gas pushes the ...
