compressed air

[ compressed air ]

summary

It refers to air that has been made under high pressure by reducing its volume by applying pressure. Using the force when high pressure air becomes low pressure

They do a lot of things, and they are used a lot in our daily life. For example, subways, mine shafts,

For ventilation, compressed air with a pressure of 0.1 kg/cm2 is used.

Various tasks are performed using the power of high-pressure air becoming low-pressure, and it is widely used in daily life.

all. For ventilation of subways, mine shafts, and buildings, the pressure is 0.1kg/cm2;

is 0.5~1kg/㎠, for transport of powders such as cement or pulverized coal, and grains in closed pipes

0.5~1kg/cm2 for air hammers, air drills, rivet hammers, etc., about 7kg/cm2 for brakes of railway vehicles or door engines

7kg/cm2 of compressed air is used for the operation of the engine, and about 50kg/cm2 of compressed air is used for fuel injection of diesel engines.

In addition, as a special thing, 100-150kg/cm2 of compressed air is used for the submersible (浮沈用). buy compressed air

A sensor that detects water is called a leak sensor.

A sensor that detects leaks.

Leak sensor is the frequency and frequency sent to the floor

Detecting the change in frequency in the presence of water

This is the principle of generating a signal.

servo motor

[ servomotor ]

summary

A device that drives a load by a control signal as a control unit of a servo mechanism.

Depending on the power source of the servomotor, there are electric (servo motor), pneumatic (air servomotor), hydraulic (hydraulic motor) and the like.

Servo motors are control motors with fast response and wide speed control range, and are classified into DC servomotors and AC servomotors according to their power. Most of the AC servomotors are three-phase servomotors.

Since these repeat operations such as stopping, starting, and reversing, they are designed to improve heat dissipation or to speed up the change of operation.

A device that drives the servomotor is required, and this is called a servomotor.

pressure gauge

[ manometer ]

summary

An instrument for measuring the pressure of a gas or liquid.

pressure gauge

There are several types of barometers, pressure differential gauges, high pressure gauges, vacuum gauges, etc. for each application, and their structures are also diverse.

According to the measurement principle, ① measuring the pressure by equilibrating it with the weight of an object (for example, 液柱), ② measuring the size to the extent that an elastic body under pressure bends, ③ pressure It is divided into using some kind of physical properties that are changed by

liquid pressure gauge

A typical example is a U-tube pressure gauge in which water, mercury, and alcohol are placed in a glass tube. When one end of the tube is connected to the pressure part to be measured, the liquid level rises and falls to a point where it is balanced with the pressure difference applied to both ends of the tube.

It is possible to measure the difference in pressure on both pipes from the difference in the height of the liquid level in the left and right pipes. There are an open type (開管式) and a closed pipe type (閉管式), and the range of pressure that can be measured is wide.

The mercury barometer is not a U-shaped tube, but in principle, it is a closed tube type liquid column pressure gauge like this one. in the industrial sense

It is also used to float a buoy, to magnify its movement with a machine, or to convert it into electricity and instruct it.

elastic pressure gauge

Although it is relatively widely used for industrial purposes, it measures the pressure by mechanically magnifying the deformation that occurs in a pressure receiving body made of metal or the like. There are Bourdon tube pressure gauges, diaphragm pressure gauges, bellows pressure gauges, and air pressure gauges (an aneroid barometer is also a kind). In general, it is easy to handle and has a wide measuring range, but the elasticity of the hydraulic material has some hysteresis and the deformation is not constant with respect to the pressure. If the pressure is applied for a long time, the deformation increases under the same pressure. There are common drawbacks.

vacuum gauge

It is a pressure gauge for measuring pressure lower than atmospheric pressure.

For the measurement of bottom), special pressure gauges such as McCloud gauge, Pirani gauge, and ionization vacuum gauge that measure the change in thermal conductivity and ion conductivity of gas according to the pressure change as the measurement principle. is used

deadweight pressure gauge

It is a type of high pressure meter that measures the pressure with a weight. There are other pressure gauges for measuring large pressures of fluids.

There are axial pressure gauges, resistance pressure gauges, and Bourdon tubes.

The pressure and pressure that pushes up the bottom surface of the piston by drawing oil such as kerosene into a cylinder equipped with a piston and

Measure by equilibrating the weight of the weight placed on it. Measures high pressures that cannot be measured with a liquid column pressure gauge.

It is used not only to set the scale, but also to calibrate the calibration of other pressure gauges.

The problem to be solved by the present invention is that there may be various causes when a passenger ship, etc. sinks.

It is intended to provide one of the fundamental alternatives to

What kind of accident would it take for such a large vessel to overturn in this way?

[0043] I can check a little bit for three reasons. Once I got the drawing and looked at it, the space at the bottom of this ship is watertight.

Several bulkheads are separated. So, in fact, even if only one space is flooded with water, the stability is not lost.

[0048] 3) In order to present a fundamental alternative in the case where it is not divided by a bulkhead

[0049] Of course, since it has not yet gone deep, even if it is overturned, if the air is pushed upwards, the space for human survival is confirmed.

It could be a boi. But here, in fact, the thing that caused the most casualties was that it suddenly tilted, and some people
