What is the formula for calculating the cylinder pressure, and what is the formula for calculating t

It also depends on what your cylinder pressure is. I used to do it at 5 atmospheres. (Of course, it can be bigger, but bigger will have other problems.)

With a diameter of 32mm, you can calculate the area of the piston. Subtracting one atmosphere (air pressure) from 5 atmospheres gives the effective pressure. The effective pressure is multiplied by the area force.

Of course, if you want to calculate precisely. Also consider the area of the cylinder rod. In this way, the force when the cylinder is extended and retracted is not the same.

The difference is the product of the effective pressure and the cross-sectional area of the cylinder rod. But this product is small.

Usually the cylinder selection manual provides the thrust calculation formula for different types of cylinders. Reference thrusts of different diameters at different pressures are also provided. That should prevail.

Cylinder pressure f = cross-sectional area of the cylinder piston.

The pressure per unit cross-sectional area of x has nothing to do with compression, but only with the pressure of compressed air (pressure per unit cross-sectional area).

The formula for calculating cylinder thrust is: f=r 2 pi 40*p. The letter p in the formula represents the air pressure you choose, pi refers to pi, r is the radius of the initial circular cylinder, and finally the cylinder thrust is calculated directly with the formula.

Suppose the cylinder runs at 50 500mm s and the cylinder with a bore of 50. The theoretical output is 100 kg under air pressure, 100 kg is equal to 50 kg for the actual output), for static loads (such as clamping, low-speed riveting, etc.), F2 resistance is very small, a, for horizontal or vertical action with cylinder speed in the range of 50 500mm s, a.

Cylinder precautions.

In places with a lot of dust, water droplets, and oil droplets, the rod side should be equipped with a telescopic protective sleeve, and when installing, there should be no twisting state. When the telescopic protective sleeve cannot be used, a cylinder with a strong wiper or a waterproof cylinder should be used.

If the ambient temperature and medium temperature of the cylinder exceed -10-60 when there is a magnetic switch, and if it exceeds -10-70 when there is no magnetic switch, anti-freezing or heat-resistant measures should be adopted.

The former formula does not take into account the frictional resistance f, the latter considers the frictional resistance f, and the latter formula is more practical.

In simple terms, it is the area of the piston multiplied by the air pressure, and the tensile force minus the area of the piston rod, (the unit of air pressure is kilograms, and the area of the piston is measured in square centimeters).

(1) p(n) thrust = 4 dxd p

2）f=p*a-f

All are true: with regard to equation (1), when ignoring the operating resistance of the cylinder, the force (p) = pressure (p) * the cross-sectional area of the cylinder (r*r), and 2r*2r 4= dd 4, therefore, p=p* r*r=p* *d*d 4, i.e. p(n) thrust = 4 dxd p

For equation (2), f=p*a-f, p*a--- pressure*cylinder cross-sectional area, f---cylinder running resistance. Obviously correct.

Pressure p f a, available force f p * a, the output of the cylinder f p (the air pressure of the input air, generally in the cross-sectional area of the cylinder bore - the cross-sectional area of the cylinder rod), remember that the unit should be unified, 1mpa = 100n cm 2

That's right, the cross-sectional area of the pull-back subtraction shaft.

Cylinders. The pressure at work is determined by the load, and the pressure of the physical force is equal to the force divided by the area of action (i.e., p=f s).

If you want to calculate the output force of the cylinder, you can calculate it according to the following formula:

Let the radius of the piston (i.e. cylinder barrel) be r (in mm) and the radius of the piston rod be r (in mm).

The pressure level p (in MPa) during operation

Then the thrust of the cylinder fpush= (unit n).

The tensile force of the cylinder f-pull= (unit n).

The pressure of the cylinder still needs to be determined according to the valve. Generally, the valve is 3-8kg. The formula for calculating the large output force of the standard cylinder:

Approximate calculations are made based on the rated air pressure and standard cylinder bore. F1 = p 4 d2 f2 = p 4 (d2- d2) where: f1 has a large theoretical output force without piston rod end (n) f1 has a large theory of piston rod end.

What are the faults that will occur after the vehicle wades in the water:

1. As the core part of the car, the engine is naturally indispensable for machinery and circuitry, so the engine is very afraid of being blistered. Once the engine is soaked in water, it can cause many problems, such as cylinder blowout, exhaust pipe corrosion, short circuit and so on.

2. ABS is a high-end device to ensure the stability of the braking direction of the car and prevent the side slip and deviation caused by fierce objects. If the ABS is blistered, the mechanical ABS will be corroded, and the electronic ABS may be short-circuited. In any case, it is a very big hidden danger to your driving safety.

3. Airbags.

An detonator is a device that detonates an airbag in a moment of crisis, and most of the detonators detonate the airbag through gunpowder. If the detonator enters the water, the gunpowder branch will naturally fail, so it is also quite dangerous.

4. Now many car owners like to install on-board electric hidden posture brains for the convenience of driving, which naturally cannot withstand the baptism of water with high-end electronic instruments.

5. The dashboard of the car is a precision instrument device, and once the water enters, the dashboard will fail. As a result, the dashboard becomes waste. (Photo by Li Linwei) @2019

Cylinder pressure calculation Gong Zhi Hu type: the pressure of the cylinder p = external load f The action area of the cylinder a.

The pressure of the cylinder is determined by the load, and the pressure of the physical force is equal to the force divided by the area of action (i.e. p=f s).

If you want to calculate the output force of the cylinder, you can calculate it according to the following formula:

The thrust of the cylinder f push = unit n).

The tensile force of the cylinder f-pull= (unit n).

r is the radius (in mm) of the piston (i.e. cylinder).

r is the radius of the piston rod in mm

P is the unit of pressure (unit MPa) at work

How the cylinder works:

As an actuator, the hydraulic cylinder is essentially an energy conversion device. The hydraulic cylinder converts the pressure energy of the incoming liquid into the mechanical energy of the linear motion of the piston.

The so-called input hydraulic energy refers to the flow rate and pressure of the input liquid, and the output mechanical energy is the velocity v (m s) and traction force f of the piston when it moves. All these parameters are achieved by the vertical cleaning of the volume, so the hydraulic cylinder is a volumetric actuator. <>

qr=。

For example, the cylinder diameter D is 10cm, the maximum speed is 300mm per s, the pressure is used, and the maximum air consumption QR of the Beiu cylinder is equal to 610A2 times 300 times (plus is equal to every min), so the solenoid valve with CV value or effective cross-sectional area of about 18mm can meet the flow requirements.

Cylinder working principle:

Generally speaking, in the case of the same displacement, the more valves, the better the intake and exhaust efficiency, just like a person who needs to open his mouth to breathe when he is tired and out of breath. Traditional engines mostly have one intake valve and one exhaust valve per cylinder, and this two-valve valve mechanism is relatively simple, with low manufacturing cost and relatively easy maintenance. For ordinary engines with low output power requirements, the two-gas potato door can obtain more satisfactory engine output power and torque performance.
