Abstract
The utility model provides an energy storage booster having good safety. The energy storage booster having good safety comprises an energy storage cylinder which is an airtight cylinder body. The energy storage booster having good safety is characterized in that two pistons are arranged in the energy storage cylinder, and the two pistons are arranged in parallel and connected through a supporting piece so as to form a gas-liquid separation structure; the gas-liquid separation structure separates an inner cavity of the energy storage cylinder into two chambers, namely a gas chamber and a hydraulic storage chamber; the positions where the two pistons make contact with the inner wall of the energy storage cylinder are provided with seal rings in a sleeved mode; a gas-liquid separation chamber is formed between the two pistons. Compared with the prior art, the energy storage booster having good safety has the advantages that when the sealing function of the pistons loses efficacy, high pressure gas in the gas chamber or high pressure liquid in the hydraulic storage chamber does not directly enter the opposite chamber and enters an isolated chamber instead, the danger caused by mixture of the gas and the liquid is avoided, the overall safety is improved, and therefore the energy storage booster having good safety is improved remarkably.
Description
Technical field
The utility model relates to hydraulic machinery, be specifically related to a kind of accumulation of energy pressurized machine, this accumulation of energy pressurized machine can be serially connected with hydraulic press, forge in the hydraulic driving system of the hydraulic machineries such as machine, pile driver soon, also can be used in the engine system of car and boat, be used for the accumulation of energy supercharging, improve the movement speed of oil hydraulic cylinder.
Background technique
Hydraulic machinery is a kind of take liquid as working medium, is used for transferring energy to realize polytechnic machine.It not only can be used for excellent suitability for press forming, also can be used for correcting, press-fits, packing, briquetting and pressing plate etc., and therefore, Hydroform process has a wide range of applications in industries such as automobile, Aeronautics and Astronautics and pipelines.
As everyone knows, the used oil hydraulic cylinder characteristics of hydraulic machinery are that active force is large, but movement speed is slow, if accelerate its speed, then must use jumbo oil pump, or adopt the modes of organizing the oil pump parallel connection with the unit time fuel delivery of raising to the oil hydraulic cylinder of hydraulic machinery, but often cause so the significantly raising of cost more.Therefore a kind of accumulation of energy supercharging is put soon device and is arisen at the historic moment, Chinese patent " energy storage quick release device " (patent No. 201020594144.1) has disclosed a kind of like this energy storage quick release device commonly used, as shown in Figure 1, this energy storage quick release device comprises at least one accumulation of energy cylinder 1, described accumulation of energy cylinder 1 is an airtight cylinder body, be provided with a piston 2 in it, by this piston 2 accumulation of energy cylinder 1 inner chamber be separated into air chamber 3 and 4 two chambers of hydraulic pressure apotheca; Establish liquid-inlet 5 and liquid outlet 6 on the described hydraulic pressure apotheca 4, establish an electric control valve on this liquid-inlet 5, supply to connect oil pump through this electric control valve; Described liquid outlet 6 is for the oil hydraulic cylinder of connecting fluid press mechanical pressing; Also comprise a pressure switch for detection of the interior pressure of hydraulic pressure apotheca 4, and this pressure switch output signal is used for the control electric control valve; Wherein, described piston 2 is aluminum alloy material, and outside the piston 2 and accumulation of energy cylinder 1 inwall contacting point is arranged with seal ring 7; Described air chamber 3 connects a gas holder 9 by a high pressure hose 8, to enlarge gas storage space.Above-mentioned energy storage quick release device can release energy when oil hydraulic cylinder moves in non-accumulation of energy actuation time of hydraulic machinery, thereby reaches the purpose that adopts the work of small capacity oil pump Driven by Hydraulic Cylinder hydraulic machinery, has certain practical improvement.Yet, the existing energy storage quick release device of this kind is found to have the following disadvantages in actual use: its piston seal ring after long-term back and forth running can wear and tear, thereby the possibility that causes gas in the air chamber and the liquid in the hydraulic pressure apotheca that mixing is arranged, and under condition of high voltage, the mixing of gas-liquid very easily causes blast, piston after seal ring is worn simultaneously also can rub inboard wall of cylinder block and produce spark in working on, have danger so that the mixing of gas-liquid becomes, and so that the overall security of energy storage quick release device have a greatly reduced quality.
Therefore, how to solve the problems referred to above that existing hydraulic machinery exists, just become the problem of the utility model research.
