Why do scroll compressors now do not need an intake valve, only an exhaust valve?

Since the beginning of the 21st century, environmental pollution has become increasingly serious, and more and more countries have begun to prepare to abandon the use of fuel vehicles and start to use new energy vehicles. Advocating the use of energy vehicles, it is not only the power generation device that will change, but also many engine accessories, including the protagonist of this article--- new energy vehicle air conditioning system.

With the popularization of new energy vehicles and the mandatory abolition of fuel vehicles in some countries, the automotive air conditioning compressor has undergone tremendous changes, canceling the front-end drive and drive wheel of the original compressor, and adding a drive motor and a high-quality control module. The air conditioning compressor no longer relies on the engine to obtain working power, and the power output of the vehicle is more stable.

Scroll compressors.

What has changed is to drive the compressor workload drive motor, because this drive motor is to be used in new energy vehicles, it is necessary to reduce the volume as much as possible under the condition of stability and reliability, and the weight must be controlled within a certain range. In addition, because it is a new energy vehicle, it is necessary to save energy and reduce emissions, so this drive motor must also have efficient operation ability, so the three-phase permanent magnet synchronous motor appears in our new energy vehicles, which just integrates the advantages of small size, high work efficiency and light weight.

Because the intake and exhaust are now one, there is no need for an intake valve.

When the intake and exhaust are in the same chamber, the intake and exhaust valves should be used to switch between the intake and exhaust.

There is no suction valve, and there is no exhaust valve, so the flow loss of airflow is small.

This is because there is no air to improve the more powerful power.

Because now the technology is more advanced, there is no need for an intake valve.

The intake valve can be replaced with the advancement of modern technology.

Cost savings can be achieved without sacrificing efficiency.

Now the intake and exhaust are one.

Because when the intake and exhaust use the same cavity, it is necessary to use the exhaust valve to switch the intake and exhaust.

The same chamber is used for air intake and exhaust.

Summary. Hello, I will help you solve this problem, the reasons and steps to solve it are as follows:

1.External impurities enter: Solid impurity particles violently impact the intake valve of the screw air compressor under the drive of the air flow, resulting in damage to the parts; Or there may be dirt caught between the sealing surfaces, making the intake valve ineffective.

2.Water in the air: Water in the air or the failure of the compressor gas-liquid separator will cause liquid shock to the air valve, and the air valve will accelerate the failure due to additional impact, which is mainly manifested as abnormal sound during compressor operation.

3.Excessive lubricating oil: The compressor cylinder is lubricated with oil, if too much oil is injected, the excess lubricating oil will form oil stickiness in the valve, resulting in the valve plate breaking due to delayed closure or opening.

4.Working condition change: Each inlet valve of the compressor is designed according to specific working conditions, and the intake valve will soon fail if the working condition fluctuates and deviates from the design value for a long time.

5.Start the machine after a long time of shutdown: After the air compressor is placed for a period of time, the liquid carried by the lubricating oil or medium of the cylinder accumulates in the cylinder, which will not only cause the erosion of the cylinder and the valve, but also cause the cylinder to start with liquid because the liquid in the cylinder is not discharged or the valve is not cleaned when the cold car starts, which is easy to cause liquid shock and oil stickiness.

The air compressor inlet valve cannot be circulated.

Hello, I will help you solve this problem, the reasons and steps are as follows: Linkback 1External impurities enter:

Driven by the air flow, the solid impurity particles violently impact the inlet valve of the screw air compressor, resulting in damage to the parts; Or there may be dirt caught between the sealing surfaces, making the intake valve ineffective. 2.Water in the air:

Water in the air or a failure of the compressor gas-liquid separator will cause liquid shock to the air valve, and the air valve will accelerate its failure due to the additional impact, which is mainly manifested as abnormal sound during compressor operation. 3.Lubricating oil excess:

The compressor cylinder is lubricated with oil, and if too much oil is injected, the excess lubricating oil will form an oil shed in the valve, causing the valve plate to break due to delayed closure or opening. 4.Condition Changes:

Each inlet valve of the compressor is designed according to specific working conditions, and if the working conditions fluctuate and deviate from the design value for a long time, the intake valve will soon fail. 5.Turn it on again after a long shutdown:

After the air compressor is placed for a period of time, the liquid carried by the lubricating oil or medium of the cylinder accumulates in the cylinder, which will not only cause the erosion of the cylinder and the valve, but also cause the cylinder to start with liquid because there is no liquid accumulation in the cylinder or the valve is not cleaned during the cold start, which is easy to cause liquid shock and oil stickiness.

Hope it helps.
