Palladium is the largest in industrial use. Although rarely purchased by investors, palladium is widely used in catalytic converters for automobiles, especially in gasoline-powered cars, which are commonly used in China.

China is a consumer of massive use of palladium in the automotive industry, and the United States is likely to be the second largest consumer of palladium. Palladium hit a record high of $1,138 an ounce in January, more than double the amount it had two years ago.

Although ETF holdings fell to a nine-year low, the metal has recently climbed sharply and is not far from the all-time high set in January. Although hedging** has become more aggressive in recent weeks, their bullish bets are only a fraction of what they started the year.

According to the Hong Kong consulting firm Precious

Philippe Lapvik, Managing Director of Metals Insights

Klapwijk said that the **large** palladium may be due to the tightening of the market and the tight supply and demand, which is mainly used for automotive catalysts. Palladium was quoted at $1, $1 per ounce on Thursday (September 27), not far from the peak of $1, in January.

The market has been in the red for most of the decade, and Klapwijk expects this to continue. "It may also encourage users to make some precautionary purchases, and certainly some speculative interest from long-term investors," he said. ”

This has helped palladium outperform other*** metals in recent weeks, which have been weighed down by a stronger dollar and expectations of rising US interest rates. More broadly, industrial goods are starting to shake off global tensions, with optimism that demand will remain strong.

Palladium is out of the woods," said Maxwell Gold, head of investment strategy at Aberdeen Standard Investments, who he believes will be further in the medium term. "Given its intrinsic demand for the automotive industry, palladium is very sensitive to industrial metals, so its recovery has been following what we have seen. ”

Demand for automobiles has led to a shortage of palladium**.

People's demand for ** is not as strong as industry, so ah, the society is not sure of things.

In general, it can be achieved by two different principles of action: one is the principle of impulsive action and the other is the principle of reactionary action. 1. The principle of impulsive actionWhen a moving object encounters another object with a lower moving speed than it, it will be hindered and change its speed, and at the same time give a force to the object that hinders it, which is called impulsive force.

The magnitude of the impulse force depends on the mass of the moving object as well as the change in velocity. The greater the mass, the greater the impulse force; The greater the change in speed, the greater the impulse. The object acting on the impulse changes its velocity and the object does mechanical work.

The simplest structure of a single-stage impulse steam turbine is shown in Figure 1 1. The steam produces expansion in the nozzle 4, the pressure decreases, the velocity increases, and the thermal energy of the steam is converted into the kinetic energy of the steam. When the high-speed air flow through the blade 3, due to the change in the direction of the air flow, the impulse force on the blade is born, and the impeller 2 is pushed to rotate to do work, and the kinetic energy of the steam is converted into the mechanical energy of the shaft rotation.

This principle of using impulse force to do work is called the principle of impulse action. 2. The principle of reactionary action is based on Newton's second law, which states that when an object exerts a force on another object, the object must be subjected to a reaction force equal to the magnitude of the force and in the opposite direction. Under this force, another object moves or accelerates.

This reaction force is called reaction power. The principle of using reaction to do work is called the principle of reactionary action. In the reactionary steam turbine, the steam not only expands in the nozzle, the pressure decreases, the speed increases, and the high-speed air flow produces an impulse force on the blades, but also expands when the steam flows through the blades, so that the steam accelerates the flow out in the blades, and also produces a reaction force on the blades, that is, the reaction force, which pushes the blades to rotate and do work.

This is the principle of reactionary action of a reactionary steam turbine.

The low-level oil tank is used for the oil pump to supply oil under normal circumstances, and the high-level oil tank is used to provide lubricating oil to the turbine-generator set bearing under the condition of power interruption and DC power supply disappearance of the plant.

The purpose of high-level exhaust is mainly to prevent air resistance, and automatic exhaust valves can be set at high-level points, such as water supply systems, fire water systems, and water supply and return systems. If the above system is used for draining at low points, it is mainly for system venting, and the shut-off valve is generally used.

If it is a steam pipe, a trap valve should be set at a low point, mainly to prevent water resistance.

Look at what pipes, generally add a valve, have a vent valve, an automatic drain.

One is to carry out a single palletizing at a high position, which is placed neatly, and the other is to palletize in a combination at a low position.

The high-level palletizer is palletized individually, while the low-level palletizer can also be palletized together with several products. The palletizer can be used in a wider range.

There is not much difference, just a high and a low;

There is a difference in the number of layers, I remember that the technician in the factory mentioned it;

It can really be said: the layman looks at the excitement, and the insider looks at the doorway.

The main unit of the high-level palletizer is composed of a trolley that can walk forward and backward, a frame and a platform that can be lifted up and down, and the work can be completed alone. The low-level palletizer is a combination of several products for palletizing.

Low-level palletizing, novel starting code mode, high-speed and high-capacity stacking;

The structure is improved, the indexing mode is advanced, and the running trajectory of the trolley is optimized;

The differential mode is used to speed up the speed of packet marshalling and stacking;

Improve the operation mode of the pallet conveyor and reduce the pallet conveying time;

It has the advantages of low cost, small size, convenient inspection and maintenance and high production capacity of low-level palletizer;

New manufacturing technology and technology are adopted, so that the performance and appearance quality of the equipment have reached the level of similar foreign products;

Control mode: PLC touch screen + standard control button + signal switch, divided into automatic manual control mode;

The fault point can be found through the touch screen, and the fault can be easily troubleshooting;

It can be customized according to customer requirements.

Brief introduction to how it works:

The main unit of Zongyi palletizer is composed of a trolley that can walk forward and backward, a frame and a platform that can be lifted up and down. The lifting platform of the palletizer is driven by the motor to move up or down to a suitable position, while the trolley moves the assembled product to the top of the pallet, and the front and rear four shaping plates clamp the carton and walk backward at the same time to drop the carton onto the pallet or the previous layer of cartons. When a stack is stacked, it is discharged by the pallet conveyor.

The high-level palletizer is a kind of high-efficiency palletizing equipment with a high degree of automation and good integration. The palletizer groups the bags in a predetermined way, and then stacks the entire layer of bags on the pallet layer by layer. It is usually used as a follow-up equipment to the packaging line to increase production capacity and transfer capacity.

It has a wide range of applications, suitable for the stacking needs of various packaging bags and cartons, reasonable structure, high equipment stability, simple operation, safe and efficient, flexible marshalling, and can adapt to pallets of various materials and sizes.

I didn't read your program, but I can remind you that if you want to be ghost-free, you need to send an extinguish code before changing the display, and you'll be fine.
