The LNG refueling function project was approved by the Guangzhou Municipal Government and will be included in the first batch of pilot projects for the construction of LNG filling stations in the city in 2012. It is reported that this is the first time that Guangzhou City has approved the construction of LNG filling station project.

Maintenance Method for Hydraulic Excavator Oil
Cooler
1, The heat dissipation components to
ensure the air circulation, as far as possible to increase the area of air
circulation. Oil Cooler hydraulic excavator to guarantee a certain air
circulation area to better protect the cooling function of the radiator, in
order to better protect the heat radiating parts of excavator dredging, the
need for timely on the radiator possible blockage fault timely cleaning.If
there is a problem of blockage of the protection network for the heat
dissipation parts of the hydraulic excavator, we need to arrange and clear it
in time, so as to ensure normal heat dissipation and prolong the service life
of the excavator.
2, May need to be vigilant, around the
radiating component of hydraulic excavator needs certain additives, these
additives must be resistant to high temperature, corrosion resistance, and
these materials need ventilation is poor, so it can prevent air backflow. The
additives of this special material are mainly vigilant for the phenomenon that
the heat sink can be reflued near the radiator after the problem of radiator
inhalation, which will cause the high temperature not to drop.
3, We need to ensure that we can guarantee
the smooth emission of heat. In order to make the hot gas better evacuated, the
diaphragms of the engine compartment doors of the hydraulic excavators can not
be disassembled at will, so that the radiator can achieve a certain cooling
effect. The exhaust holes of the engine hatch need to be ensured unblocked, and
the vent holes are not blocked or placed in order to better discharge the heat.
4, To cover the cooling part of the air
intake to have a certain guarantee. The air guide hood and fan will also affect
the intake volume of the radiator of the hydraulic excavator. According to the
need, the air guide cover can be chosen in three ways: Venturi, ring type and
box type. The position and distance of the fan and air guide cover and its
engine are also required. Reasonable control should be made according to the
needs of the field operation.
5, It is necessary to guarantee the
resistance and problems of the import and export of hydraulic excavators within
the scope of control. The hydraulic excavator engine has certain requirements
for the environmental atmosphere. The general accuracy requirement of
filtration is 5um. Generally speaking, the filtration accuracy of the domestic
diesel engine is within the range of 20um. When selecting air filter core,
reasonable selection and treatment should be made according to the need of the
heat dissipation of hydraulic excavator.
6, The maintenance of any professional
maintenance personnel should be required for any engineering machinery or
accessories. In the high temperature weather, it is necessary to check whether
the heat dissipation system can be heat dissipating regularly, and can ensure
the safety and normal construction of the construction machinery.

LPG, LNG planning and construction has not yet introduced new policies. Although Guangzhou Petroleum has used various channels to seek LNG project development, it has never made a breakthrough. In June this year, the Guangzhou Municipal Development and Reform Commission held a meeting on the planning and construction of LNG filling stations, and proposed to implement the pilot work of LNG filling stations before the end of the year. Taking this opportunity, Guangzhou Petroleum took the initiative to attack, the main responsible person personally participated, visited the relevant government departments many times, and strengthened the advantages of Sinopec's network distribution, safety management, gas source protection, etc., and received the support of the expert group. The planning points were all approved by experts and approved for the pilot construction.
