Information

Someone said: My laboratory has decentralized gas supply, and the gas supply is good. Why do I spend the money to install a laboratory for centralized gas supply? Do I have nothing to do when I'm full? I still think I have a lot of money, so I can make it hard!

 

At first glance, don’t you think it makes sense, after all, the cost can be controlled a little bit, and it’s human nature, right? mistaken! Wrong!

 

cost? What does the laboratory do? They are doing experiments, they are developing new products! Then let me ask you again, is the high cost of gas? Or is the R&D cost of the product high? It's clear at a glance, isn't it! Then, if I tell you, the purity and supply time of the gas will seriously affect the quality of the products produced in the laboratory, and the centralized gas supply in the laboratory can maintain the purity of the gas and achieve continuous uninterrupted gas supply! How would you choose? If it's me, I will choose the laboratory for centralized gas supply!

 

Less effort? My friend, gas cylinders are not light. It’s not easy to move around when changing gas cylinders. Besides, from the perspective of ensuring the safety of its storage and use, can it protect the analysis and testing personnel from toxic and harmful gases in the experiment? Yes, because:

① Some of the gas used in the laboratory is flammable, explosive, toxic, and highly corrosive. Once it leaks, it may cause damage to staff and equipment;

② If multiple gases are used in the same environment, if there are two kinds of gases that can cause strong chemical reactions such as combustion or explosion to leak at the same time, it may cause damage to staff and equipment;

③ The outlet pressure of most gas cylinders can reach up to 15 MPa, which is 150 kg/cm2. If the gas cylinder mouth pressure reducing device fails, some parts may be lased out, and the energy will be fatal to the human body or equipment.

 

So, friend, are you still afraid of taking this effort? Someone may have said: Is it so dangerous? Are you alarmist! Friends, you must know that you can overcome danger countless times, but as long as danger beats you once, it is enough to make people regret it! Therefore, safety is the first element of our construction!

 

Let’s talk about the centralized gas supply system in the laboratory. As a complete gas application system, the centralized gas supply system in the laboratory has more than the above two advantages. Directly introduce its nine most basic advantages:

 

1. Maintain gas purity

The Gaspark centralized gas supply switching system is a gas cylinder gas supply system designed for the supply of laboratory gas (its leakage rate is 1*10-8mbarl/s). In the standard configuration, each gas cylinder is equipped with a high-pressure blower. Sweep the valve to eliminate the impurities introduced every time the gas cylinder is replaced, ensuring the purity of the gas at the end of the pipeline.

 

2. Uninterrupted gas supply

Gaspark's centralized gas supply switching system can switch between gas cylinders manually or automatically to ensure continuous gas supply.

 

3. Stable gas pressure

The system adopts two-stage pressure reduction (the first stage is regulated by the air supply control system, and the second stage is regulated by the control valve at the point of use) to supply air, which can have a very stable pressure.

 

4. High efficiency

Through the gas supply control system, the gas in the cylinder can be fully used, the residual gas margin can be reduced, and the gas cost can be reduced.

 

5. Easy to operate

All the gas cylinders are concentrated in the same location, which reduces operations such as transportation and installation, and saves time and costs.

 

6. Reduce the rent of gas cylinders

The use of a centralized gas supply system can reduce the requirements for the number of gas cylinders, thereby saving the rental cost of gas cylinders.

 

7. Reduce the loss of molecular sieve

Centralized gas supply can better control the gas purity (through cleaning and purging), which can effectively reduce the amount of molecular sieve used by several parties (cost savings).

 

8. Airless cylinders in the laboratory

The use of a centralized gas supply system means that there is no gas cylinder equipment in the laboratory, which has the following advantages:

---Improve safety. The gas cylinder may fall to the ground and cause damage or injury.

---Improve the sense of security. Gas cylinders may cause dangerous situations such as gas leakage and fire.

---save space. Removing the gas cylinder from the laboratory can free up more experimental space.

 

9. Other benefits

---Reduce the damage and loss rate of the control valve.

---It is more convenient to shorten the length of the connecting pipeline between the gas valve and the instrument.
