Lined type piston energy accumulator with alarming function

Abstract

The invention discloses a lined type piston energy accumulator with an alarming function. The lined type piston energy accumulator with the alarming function comprises a protective cap, a heavy type inflation valve, light type spring washers, hexagon socket cap screws, a high-pressure medium sensor, a gas side end cover, a shell, a piston, a support ring, a bidirectional seal device, a one-way seal device, O-shaped seal rings, check rings and an oil side end cover. A 316L stainless steel lining is arranged in the shell. The two ends of the shell are provided with the gas side end cover and theoil side end cover through the O-shaped seal rings and the check rings. The gas side end cover is provided with the high-pressure medium sensor and the heavy type inflation valve. The protective capis fixed to the gas side end cover by the light type spring washers and the hexagon socket cap screws and located outside the heavy type inflation valve. The piston is arranged in the shell through the support ring, the bidirectional seal device and the one-way seal device. The lined type piston energy accumulator with the alarming function is reasonable in structural design, good in pressure bearing effect, low in cost and resistant to corrosion, the work state of the energy accumulator can be effectively detected in time, timely replacement and maintenance are guaranteed, and then system functions are guaranteed.

Description

technical field [0001] The invention relates to the technical field of accumulators, in particular to a lined piston accumulator with an alarm function. Background technique [0002] The accumulator is an indispensable auxiliary device in the hydraulic system, which can not only play the role of buffer and noise reduction, but also save a lot of energy, so it is widely used in the hydraulic system. According to the structure of the accumulator, the current common accumulator products mainly include bladder type and piston type. Among them, the bladder type accumulator cannot withstand frequent pressure fluctuations and large loads, otherwise it will easily cause bladder rupture accidents. The bladder accumulator makes up for the defects of the bladder accumulator. [0003] Commonly used piston accumulators on the market are single-layer carbon steel, alloy steel or stainless steel. It cannot be effectively controlled in terms of pressure bearing, corrosion resistance and c...

AI Technical Summary

Problems solved by technology

It cannot be effectively controlled in terms of pressure bearing, corrosion resistance and cost

Moreover, the commonly used piston accumulator has no alarm device, which cannot effectively detect the working state of the accumulator, cannot guarantee timely replacement and maintenance, and may even affect the system function.
