Standard configuration and working principle of LPG skid-mounted station

LPG skid-mounted station standard configuration: hydrocarbon pump, motor, belt pulley, base, alarm, inverter, control box, spray pipe, float type liquid level gauge, pressure gauge, thermometer, safety valve, safety return valve, filter , Check valve, ball valve, stop valve, pipeline safety valve, unloading pipe, shockproof pipe, flange, metal gasket, 8.8 bolt, electronic filling scale, pipeline, off shelf. Compressors can be installed on demand.

LPG skid-mounted stations must not only be safe and reliable, but more importantly, practical. Unlike LPG stations, LPG skid-mounted stations have enough space to arrange equipment. How to arrange all supporting equipment in a small space and make them work safely , Need designers to conceive. The working principle of LPG skid-mounted station mainly has the following points:

1. 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.

2. 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-mounted station is generally not large. If the loading and unloading operation speed is too fast, the storage tank of the skid-mounted station cannot hold too much LPG for a while, and danger will occur. 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.

3. The place where the tank body of the LPG skid-mounted station is connected to the pipeline will also be equipped with an emergency shut-off valve and a concentration alarm. In case of leakage or emergency, double insurance can be used.

The LPG skid-mounted station produced by Chengli Company has the following volumes (cubic meters): 5 cubic meters, 8 cubic meters, 10 cubic meters, 12 cubic meters, 15 cubic meters, 20 cubic meters, 25 cubic meters, 32 cubic meters, 40 cubic meters, 45 cubic meters, 50 cubic meters, 60 cubic meters, 65 cubic meters, 80 cubic meters, 100 cubic meters.
