Embodiment 1

[0023] A kind of LNG liquid filling equipment, such as Figure 1-5 As shown, it includes a motor 2, a two-chamber box body 5, a two-head pump shaft 7, and a pump head 9. The two-chamber box body 5 is set on the bottom plate 1. One end of the two-head pump shaft 7 is connected to the motor 2 through a pulley 4, and the two-head pump shaft 7 Turn the motor's rotating motion into reciprocating motion. The motor 2 is connected to the electric control cabinet. Two pump shafts 7 are arranged in the two-chamber box body 5. The surface of the two-chamber box body 5 is provided with an end cover 6, and one end of the two-chamber box body 5 is supported The frame 8 is connected with the pump head 9, and the two-chamber box body 5 adopts the form of splashing oil, which greatly extends the life of the transmission system.

[0024] Two eccentric wheels 10 are arranged on the two-head pump shaft 7; the working efficiency of the equipment is increased. The eccentric wheel 10 is built into the...

Abstract

The invention relates to the field of petroleum industry, in particular to an LNG (liquefied natural gas) filling device. The LNG filling device comprises a motor (2), a two-chamber box (5), a two-head pump shaft (7) and a pump head (9). The two-chamber box (5) is disposed on a base plate (1). One end of the two-head pump shaft (7) is connected with the motor (2) through a belt pulley (4). The motor (2) is connected with an electric cabinet. The two-head pump shaft (7) is disposed in the two-chamber box (5). An end cover (6) is disposed on the surface of the two-chamber box (5). One end of the two-chamber box (5) is connected with the pump head (9) through a support frame (8). During operation of the LNG filling device which is stable in pressure, the motor is not in contact with liquefied natural gas, heat generated is dissipated to the air, flash steam emission is reduced, and operation cost is lowered. A plunger pump is used, a motor of the plunger pump is located outside the pump, the size of the pump is reduced, and energy consumption of the pump is lowered.

Description

Technical field [0001] The design of the present invention relates to the field of petroleum industry, in particular to an LNG liquid filling equipment. Background technique [0002] With the development of society, cars have become an indispensable means of transportation for people's family life, daily work, transportation and tourism. With the increasing depletion of oil energy, oil prices are also changing the law all the way arbitrarily, which has caused the embarrassment of many families who can afford but can’t afford a car; at the same time, with the emergence of various extreme environments, environmental protection has become a society. Hot topics: China is rich in natural gas resources, and natural gas has the advantages of single composition, high purity, low sales price, low CO and other pollutant gas emissions, and good engine performance when starting at low temperatures. Before real alternative energy sources were invented , The demand for natural gas will contin...
