RUPrinciple of cng skid-mounted station, what are the scope of application of cng skid-mounted station
The cng skid-mounted station is not only safe and reliable, but more importantly, it is practical. It is different with the liquefied gas station, the cng skid-mounted station has enough space to arrange the equipment. How to arrange the supporting equipment in a small space and make it work safely , Need designers to conceive. The working principle of cng skid-mounted station mainly has the following points:
There must be a safe and reliable circuit system. Pumps, electronic filling scales and compressors all need electricity to drive, and the circuit must be designed to be simple and easy to operate. When purchasing the motor, please pay attention to the explosion-proof and anti-static type. Because the liquefied gas meets sparks, it will explode when the concentration is too high.
A complete liquid phase, gas phase, and return system, which requires designers to be very familiar with the principle of liquefied gas stations. When the liquid phase and gas phase of the skid-mounted station are connected to the tank car, the liquefied gas in the tank car is in the compressor Pour into the storage tank under pressure. However, the volume of the skid loading station is generally not large. If the loading and unloading operation speed is too fast, the storage tank of the skid loading station cannot hold too much liquefied petroleum gas for a while, and there will be danger. Therefore, the designer will design the return line on the liquid phase pipeline and install a safety valve on the pipeline. Once the pressure in the pipeline is too high, the safety valve will open and leak too much liquefied gas and propane, thus ensuring the overall Safety.
The place where the tank body of the cng skid-mounted station is connected to the pipeline will also be equipped with an emergency shut-off valve and a concentration alarm. In the event of leakage or emergency, double insurance can be used.
The cng skid-mounted station has the characteristics of fire-proof and explosion-proof, small area, easy to move, etc. The products are widely used in bus stations, ports, docks, airports, large construction sites, internal gas stations, etc.
