Engine antifreeze fluid filling equipment and method

Abstract

The invention provides engine antifreeze fluid filling equipment and method. The equipment comprises an antifreeze liquid filling bucket, an electric oil pump, a filling pipeline, a backflow pipeline and a detecting device. The antifreeze liquid filling bucket is arranged on a filling rack. The electric oil pump is connected with the antifreeze liquid filling bucket and used for filling an engine with the antifreeze liquid. The filling pipeline is connected between the electric oil pump and the engine and used for filling the engine with the antifreeze liquid. The backflow pipeline is connected between the engine and the antifreeze liquid filling bucket and used for exhausting air in a refrigerating system from the antifreeze liquid in the antifreeze liquid filling bucket. The detecting device is used for detecting whether the air in the refrigerating system of the engine is exhausted or not. By means of the engine antifreeze liquid filling equipment, the air in the refrigerating system of the engine can be exhausted rapidly, the refrigerating system of the engine can be filled with the antifreeze liquid rapidly, the manual filling time is shortened, the filling efficiency is improved, and the pollution on vehicles and the environment in the antifreeze liquid filling process is reduced.

Description

technical field [0001] The invention relates to the technical field of automobile filling, in particular to an engine antifreeze filling device and a filling method. Background technique [0002] At present, when filling the cooling system of traditional vehicles with antifreeze, there are three main methods to remove the air in the cooling system: [0003] (1) In the production line of the assembly plant, the antifreeze liquid is filled after the antifreeze filling port is evacuated. The disadvantage of this method is that the required equipment is complex, cumbersome and inflexible, and the equipment requirements are high. [0004] (2) In the after-sales service of the vehicle, the maintenance worker uses the method of directly filling the filling port. The disadvantage of this method is that the filling time is long and the air is not clean, which often leads to the high temperature of the engine and even the consequences of the engine pulling the cylinder. .

AI Technical Summary

Problems solved by technology

[0003] (1) In the production line of the assembly plant, antifreeze is filled after the antifreeze filling port is vacuumed. The disadvantage of this method is that the required equipment is complex, heavy and inflexible, and has high requirements for equipment

[0004] (2) In the vehicle after-sales service, the maintenance workers use the method of filling directly to the filling port. The disadvantage of this method is that the filling time is long, and the air is not exhausted cleanly, which often leads to engine high temperature and even engine cylinder scuffing.

[0005] (3) Use the cooling unit antifreeze filling device and the cooling unit antifreeze filling system, mainly to complete the electric vehicle cooling unit filling device. Its disadvantages are: the power supply used by the water pump is not convenient to connect; the single water channel circulates the air It is not only slow to fill the engine cooling system but also the air is not clean (the engine cooling system has two cycles of large and small); the filling system is not integrated, which is inconvenient to use
