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 !

How to Prevent Hydraulic Oil From Emulsifying On Concrete Mixer Truck?

The main cause of hydraulic oil emulsification on concrete mixer truck s is water in the hydraulic system, which is mixed with water after a long time. The removed hydraulic oil will form an emulsification of the hydraulic oil. We found that water enters the hydraulic system due to the following reasons: a. Working in a humid environment, the moisture in the air condenses due to the alternation of cold and heat, turning into water droplets and falling into the oil; b. The rainwater on the fuel tank seeps into the fuel tank due to the weak sealing of welding and connection parts; c.  Due to the damage of the pumping cylinder seal and the damage of the mixing motor, moisture is brought into the oil; d. Daily maintenance, cleaning, oil change, and maintenance process bring in moisture. To prevent the oil from emulsifying, we must first prevent moisture from entering the hydraulic system. When the car leaves the factory, the welding and connection parts must be manufactured in accord...

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...
