How does the hydraulic system achieve secondary pressurization?

The secondary pressurization of the hydraulic system generally refers to the increase of the pressure and power of the system by adding an auxiliary pump or hydraulic cylinder to the main hydraulic system.

Specifically, there are two ways to repressurize:

Auxiliary Pump Boosting: Add an auxiliary pump to the main hydraulic system and connect it in parallel or series with the main pump to increase the total output pressure and flow of the system. Auxiliary pumps are usually installed at the outlet of the main pump or in the tank.

Hydraulic cylinder pressurization: add a hydraulic cylinder to the main hydraulic system, place it at the outlet of the main pump, and use the compression effect of the hydraulic pressure to further increase the pressure of the hydraulic oil. This method needs to consider the size and working conditions of the hydraulic cylinder, but the ordinary booster cylinder is generally a non-standard product and is expensive.

The Dextron Hydraulic Booster is a standard booster cylinder. At the same time, the system is equipped with this hydraulic supercharger, which can completely separate the high-pressure system and the low-pressure system, greatly reducing the system cost, improving safety and reducing energy consumption.

Either way, the purpose of secondary pressurization is to increase the output power and pressure of the hydraulic system to meet the higher demands of the operation.

Hydraulics. Pressurization, simply put, is the area ratio.

There are professional superchargers, and you can also do it yourself.

As a simple example, an oil cylinder.

The area of the rodless cavity is larger than the area of the rod cavity, so if the rod cavity of the oil cylinder is blocked and the rodless cavity is pressurized, then the pressure in the rod cavity will be higher than the system pressure, which will cause secondary pressurization, provided that there is hydraulic oil in the rod cavity.

with a continuous hydraulic supercharger.

It's easy to do, for example

The first low-pressure walk to full stroke, then pressurized;

Then the system holds the pressure until it is another pressure (high pressure).

The pressure is then relieved through the relief valve.

There are many ways to do this, and it's best to introduce your system and I'll take a look at it for you.

In the process of oil suction, the volume continues to increase, and at the maximum volume, the closed cavity of the hydraulic oil is disconnected from the oil suction port, and the oil suction stops. The volume is then reduced and the oil outlet is connected at the same time until the volume is minimized.

The volume at the beginning of the suction and the end of the oil outlet are the same, but what really works is the volume change process in the middle.

Of course, it is not at all possible when playing in the game, but it is effective when taking photos and appearing in magazines. You can apply the hydraulic system to pressurize the body while shooting, so as to get more Minzen moneyIn addition, the hydraulic system pressurization can slowly fill up the sentence to take your n2o

Usage: Press and hold first, then press the front and back buttons to pressurize.

You have to make sure that you have installed the hydraulic system, if you are disturbing, press h in the game, j, think that these two keys are pressing the bias key, for example: press the throttle button, the front of the car will raise the imitation hand, if you apply the potato eggplant hydraulic start, the start is very fast, but the speed spans 30 miles per hour, it will be ineffective.

Here is the schematic diagram of a hydraulic supercharger and its workflow is as follows.

1) The three-position four-way valve 1 is turned on in the left position, and the pressure oil control check valve 6 enters the rodless cavity of 7, and the 7 piston is pushed to move downward rapidly, and when it touches the workpiece or encounters resistance, the pressure rises. When the pressure rises to 2 to set the pressure, the pressure oil enters the booster cylinder 2 and pushes the piston to pressurize.

At the same time, cylinder 2 has rod cavity oil return, and cylinder 7 has rod cavity to return oil after the pressure rises to 3 to adjust the pressure.

2) when the right position of the three-position four-way valve 1 is turned on, its pressure oil is divided into two ways, one of which is through the check valve to the 7 rod cavity, promotes the 7 piston to move upward, and its rodless cavity returns oil through the hydraulic control check valve. The other way opens the hydraulic control check valve and enters the 4 rod cavities, pushes the piston to move to the left, moves left to the end point and then fills the booster cylinder, and the 4 rodless cavities return oil through the check valve.

I won't make a diagram and won't modify the multi-stage pressure regulating circuit, but I'll probably tell you: the two-stage pressure regulating circuit changes the valve 4 to the manual two-position two-way reversing valve and the relief valve only need one connection on the line.

Note: The two-position two-way directional valve selected has O type (normally closed) H type (normally open) It is best to adjust the pressure of the relief valve 1 to be greater than 2, and if you don't understand, add Q to talk about 361406995

Do you want to implement two-stage pressure or remote pressure regulation? The former can be equipped with a two-stage pressure relief valve (a three-stage relief valve is also available). The latter is connected directly to the regulator of the main relief valve.

Proportional relief valves can be connected in parallel or series.

It is enough to use a multi-stage relief valve.

Formulation plan of pressure control of hydraulic system:

When the hydraulic actuator works, the system is required to maintain a certain working pressure or work within a certain pressure range, and some need to adjust the pressure continuously in multiple stages or steplessly.

In the volumetric speed regulation system, the variable pump is used to supply oil, and the safety valve is used to play a safety protection role.

In some hydraulic systems, sometimes high-pressure oil with a small flow rate is required, and a booster circuit can be considered to obtain high pressure instead of a separate high-pressure pump.

In the working cycle, the hydraulic actuator does not need to supply oil for a certain period of time, and it is inconvenient to stop the pump, it is necessary to consider the selection of the unloading circuit.

In a certain part of the system, when the working pressure needs to be lower than the pressure of the main oil source, the use of a decompression circuit should be considered to obtain the required working pressure.

The hydraulic pump provides power to the hydraulic oil to propel the hydraulic actuator to work.

Within the set system pressure, the pressure of the hydraulic oil is determined by the load, for example, if the load of the cylinder is very low, only a small amount of hydraulic pressure can make the cylinder work.

If the load is too large and the pressure exceeds the system setting pressure to push the actuator to work, the system safety valve is relieved.

In the sealed hydraulic system, the hydraulic pump inputs the pressure oil into the system, and the external load can not move when the pressure is held up until the system pressure can overcome the external load movement, at this time the pressure does not increase, and the hydraulic oil pushes the load movement to do work.

Hydraulics. The pressure is trapped through the relief valve.

It is established to maintain the pressure of the ridge system within the range of the relief valve, to push the load when the load is lower than the set pressure, and to relieve the pressure when the load is higher than the set pressure to ensure the safety of the hydraulic system.
