Description

II

Изобретение относитс к гидравлическим мультипликаторам давлени непрерьвного действи и может найти применение в различных отрасл х машиностроени , например в гидропрессостроении.The invention relates to hydraulic pressure multipliers of continuous action and can be used in various fields of engineering, for example, in hydraulic press construction.

Известен гидравлический мультипликатор давлени непрерывного действи , содержащий корпус с установленными в нем плунжерами высокого давлени , соединенными со стороны свободных торцов каналами высокого и низкого давлени с обратными клапанами, расположенные соосно плунжерам приводные поршни, три проточные выточки, размещенные в зоне поршней, и линию слива ij.A continuous hydraulic pressure multiplier is known, comprising a housing with high pressure plungers mounted therein, high and low pressure channels connected to the free ends, with non-return valves, drive pistons arranged three axially along the plungers, located in the area of the pistons, and drain line ij .

Такой мультиплика.тор вл етс наибопее близким к описываемому по технической сущности.Such a cartoon is. The torrent is most closely related to that described by its technical nature.

Недостатком его вл етс конструктивна сложность.The disadvantage of it is constructive complexity.

Целью изобретени вл етс упрощение конструкции мультипликатора.The aim of the invention is to simplify the design of the multiplier.

Это достигаетс тем, что в предложенном мультипликаторе каждый приводной поршень одним из своих торцов установлен в контакте с торцом соответствующего плунжера, при этом средн вьн точка в зоне каждого из поршней подключена к полости, образованной свободным торцом другого поршн , а крайние проточные выточки соединены одна с линией слива, а друга с каналом низкого давлени .This is achieved by the fact that in the proposed multiplier each drive piston is installed in contact with the end of the corresponding plunger with one of its ends, while the middle point in the area of each of the pistons is connected to the cavity formed by the free end of the other piston, and the extreme flow undercuts are connected a drain line, and a friend with a low pressure channel.

It has a housing 1 in which cavities 2 and 3 are placed under the drive pins 5 and 4, Cavities 6 and 7 are equipped with check valves 8–11 and high plunger 12 and 13 valves. Channel

Claims

15-2O are made respectively in cavities 2 and 3, and the pistons 4 and 5. The low-pressure channel 21 serves to rest the liquid with a pop-up pressure into the recesses 1.7, 18 and to the check valves 10, 11. The highways 22 and 23 respectively provide an average recess 16 with cavity 3 and middle bore 19 with cavity

2. Cavities 2 and 3 are respectively connected with drainage line 24 and discharge line 25, Cavity 6 and 7 are connected to high pressure channel 26. The pressure multiplier can start its work regardless of the initial position of the drive pistons 4 and 5 If the drive pistons are, for example, measures in the rightmost position, when the fluid is fed into the low pressure channel 21, the fluid passes through check valves 10 and li enters cavity 6 and 7, under the tornes of plungers 12 and 13, and through the flow through, recess 17, recess 16 and trunk 22 into cavity 3, under the butt end of 5, due to the difference in the areas of the piston S and the plunger 13, the first one continues to remain in the extreme right: position. Under the action of a low-pressure fluid, the plunger 12 moves the drive piston 4 into Evo, extracting the fluid from the cavity 2 under the piston 4 through the line 23, through the middle recess 19 and the recess 20 In the discharge line 25. This piston 4 opens the recess 15 connecting the drain line 24 through line 22 with poloet i3 under the drive piston 5, the flow of pressure at the turn of the piston S, the plunger 13 moves it in a heel. The drive piston S opens a recess 18 that connects pin 19 and line 23 s. graze 2 under the drive piston 4 through the low-pressure cage of the channel 21. The working stroke of the drive piston 4 begins. 1 When moving to the right, the live sewer 4 closes a recess 17 connecting through recess 16, line 22, cavity 3 under the drive piston 5 to the low pressure channel 21. The working stroke of the driving piston 5 begins. The last action on the plunger 13 moves it to the right, displacing the liquid from cavity 7 through a check valve 9 € 0 by converting the pressure equal to the ratio of the areas of the driving 5 and plunger 13. Then the multiplier operates continuously in the described order . Through channel 14, leakage takes place and communicates with the atmosphere of the cavities in which the torps of the driven pistons 4 and 5 and the plungers 12 and 13 interact. Invention Hydraulic continuous pressure multiplier comprising a housing with high-pressure plungers connected thereto free ends of the low-pressure and low-pressure channels with non-return valves, driven coaxially to the plungers, pistons, three flow-through recesses located in the area of the pistons, and a discharge line that differs m, that, in order to simplify its structures,: each drive piston is installed in such a way that it contacts one of its ends with the end face of the corresponding plunger, while the average undercut in the area of each of the pistons is connected to the cavity formed by the free end of the other piston; - The end flow VLOCHKI are connected one with the drain line and the other with the low pressure channel.
