Process
1, Guide the LPG tank truck or LPG tanker trailer to park at the side of LPG skid station and wait for the driver to pull hand brake ,turn off the car engine, put a anti-slide block behind the wheel!

2, Check the liquid petroleum gas testing sheet, check the liquid ,check the liquid level , pressure and temperature of  LPG tanker truck and LPG tank ,check the valve and flange connections for leaks .

3, Connect the electrostatic ground wire ,remove the quick connector cover, connect the gas hose and liquid hose between the LPG skid station and LPG truck (or LPG trailer ) firmly, open the relief valve , evacuate air in the tube with the station liquefied petroleum gas or propane  and close the relief valve .

4, Loading gas from LPG TRAILER (or LPG truck) to LPG skid station
a, gas phase system : open the gas outlet of pipe of LPG skid station  to the vapor outlet of the LPG tanker (or LPG trailer)
b, liquid phase system: open the valve between the lpg tanker liquid phase and lpg skid station liquid phase .open the tanker emergency shut-off valve and slowly open it when hearing the opening sound .
open the valves :1, 3,5,6,(liquid phase ) 2,7( gas phase ),close other valves
c, start the pump and motor
d, when gas pressure of lpg tank trailer is higher than the receiving lpg skid station 0.2-0.3 mpa ,the liquid flow from the trailer  to the lpg skid station . when trailer level close to zero , close the pump and motor timely .close the valve between the LPG trailer and lpg skid station liquid phase ,close the valve between the lpg trailer and lpg skid station gas phase
e, close the lpg trailer (or lpg tank)emergency  shut-off valve .remove the hose and static grounding wire after pressure relief ,cover the quick connector cover .

5, Filling the LPG gas from the lpg skid station to cylinders
a, open the valve 8, 4,9,7(liquid phase ) other valves closed
b, start the LPG pump with motor
c, start the lpg filling scale ! The liquid from the lpg skid station through the pump pressurzing !

What is a flatbed semi trailer?

  A   flatbed semi trailer   is a very useful platform that is used in the shipping industry. It is primarily used for the transportation of shipping containers of different sizes. This is a long flat platform of either 20ft, 40ft, 48ft or 53ft length used for carrying shipping containers.  The flatbed semi trailer has no roof or walls to the side. It is a bare platform on which different container sizes are secured using container locks ready for transportation.The size of the FengYuan flatbed semi trailer loading area is determined according to the standard container size. A twist lock device for fixing the container is provided at positions corresponding to the four corners of the bottom of the container. However, it can also be used to take up other different types of loads. These different types of flatbed trailers have different capabilities and usefulness for various applications as discussed in here. Understanding their operations and basic specification...

Ten Daily Maintenance Habits Of Compactor Garbage Trucks

  The compression garbage truck has the characteristics of simple garbage collection method, high compression ratio, large loading capacity, automatic operation, good economy, double insurance system, and turning mechanism. These characteristics make the compression garbage truck become the leader among the special sanitation vehicles, so the hydraulic compression garbage truck is used very frequently in peacetime. Frequent use requires more maintenance by the user to avoid wear or overload of accessories, which will easily cause the function of the compressed garbage truck to decline in the long term, and it will age quickly. 1. The chassis and engine parts are maintained in accordance with the chassis manual of the relevant vehicle type. 2. Check the oil level of the hydraulic oil tank before working every day. Inspection method: pushing oil cylinder, scraper oil cylinder and sliding plate oil cylinder are in the fully retracted position, and the filler is closed. Observe tha...

Treatment After the Vacuum Suction Truck Pumps Out of Tank

 The vacuum suction truck uses a vacuum pump to evacuate the tank and then uses atmospheric pressure to press sewage into the tank. Normally the vacuum suction truck will be equipped with an anti-overflow valve. The anti-overflow valve can prevent the tank from being pumped to a certain extent. But because the principle of the anti-overflow valve is to connect the air inside and outside the tank after being floated by the sewage, so that the air pressure can be balanced, and the vacuum environment can be destroyed to prevent the full suction effect. There is no sound in actual use. If you do other things and don’t pay attention when suctioning sewage, it will lead to flooding. Because after the anti-overflow valve of the sewage suction truck is opened, it will take time for the air pressure inside and outside the tank to balance, about a few seconds. It may have filled the tank in a few seconds. And if it is working at high power, the air flowing into the tank from t...
