Research on utility model patent, hydraulic CNG filling substation and its pipeline system, control system and control method; The utility model patent, a refueling substation, its pipeline system and control system; Invention patent, a gas filling substation and its pipeline system, control system and control method.
Two-wire intelligent hydraulic substation series products are a new generation of hydraulic substation products developed by integrating the working principles of hydraulic substation system, compressor substation system and automatic oil vending machine. Compressed natural gas is transported from the master station by vehicle-mounted gas cylinders, and then processed by this set of equipment to realize high-speed, stable and continuous refueling of natural gas-fueled vehicles.
In this system, the vehicle-mounted gas cylinders are divided into two groups, and the gas filling capacity is significantly improved. One group is used as a low-pressure bottle group to directly supply air to the vending machine, and the other group is used as a high-pressure bottle group to supply air to the vending machine after being pressurized by a hydraulic pump, which greatly improves the inflation capacity. Using frequency converter to control the speed of variable frequency motor can increase the liquid injection capacity of hydraulic pump and increase the gas filling speed when the number of gas filling vehicles increases or the high and low pressure bottle groups change.
Using 75 kW main motor, the system processing capacity can reach 3000 ~ 5000 N cubic meters/hour, which is much higher than other equipment in the industry, reducing power consumption and operating costs.
