Detailed Description
The attached drawings are preferred embodiments of the device for accurately metering the lubricating oil additive, and the invention is further described in detail with reference to the attached drawings.
Example 1:
as shown in the attached figure 1, the lubricating oil additive precise metering device comprises a metering pump 1, a connecting pipe 3, a conveying pipe 2, a liquid collecting tank 4, an opening and closing device 5 and an air pipe 6.
The metering pump 1 is also called a quantitative pump or a proportional pump, can meet the requirements of various strict process flows, can be steplessly regulated within the range of 0-100 percent in flow rate, and is a special volumetric pump for conveying liquid (particularly corrosive liquid). Metering pumps are one type of fluid delivery machine that are characterized by the ability to maintain a constant flow rate independent of discharge pressure. The metering pump can simultaneously complete the functions of conveying, metering and adjusting, thereby simplifying the production process flow. By using a plurality of metering pumps, several media can be input into the process flow according to an accurate proportion for mixing. Due to its own prominence, metering pumps are now widely used in various industrial fields such as petrochemical industry, pharmaceutical industry, food industry, and the like.
The upper end of the connecting pipe 3 is communicated with the outlet of the metering pump 1, and the additive discharged by the metering pump 1 directly enters the connecting pipe 1. The lower extreme of connecting pipe 3 and conveyer pipe 2 through connection, 2 lower extremes of conveyer pipe and collection liquid jar 4 through connection, by shown in figure 3, the exit of collection liquid jar 4 is equipped with the device that opens and shuts 5, and the device that opens and shuts 5 can adopt butterfly valve or stop valve.
The inside annular air chamber 31 that is equipped with of connecting pipe 3 lateral wall, be equipped with the fumarole 32 on the connecting pipe 3 inner wall, fumarole 32 and annular air chamber 31 through connection, trachea 6 sets up in connecting pipe 3 outsidely, trachea 6 and annular air chamber 31 through connection. The air pipe 6 can be connected with an air supply system of a factory to supply air, and can also be independently connected with an air outlet of equipment such as a fan, an air compressor and the like.
Example 2:
the other contents of this embodiment are the same as embodiment 1, except that: the upper end surface of the liquid collection tank 4 is provided with an exhaust hole 41, and the exhaust hole 41 plays a role in stabilizing pressure, so that the air pressure in the liquid collection tank 4 is kept unchanged.
The conveying pipe 2 and the liquid collecting tank 4 are both vertically arranged. The lower end of the conveying pipe 2 penetrates through the liquid collecting tank 4, and the tail end of the conveying pipe 2 is lower than the top surface of the liquid collecting tank 4. This kind of arrangement ensures that the additive that conveyer pipe 2 flowed out can not glue the top of gathering liquid jar 4, and when trachea 6 was blown the conveyer pipe 2 simultaneously, gaseous entering can blow downwards behind the jar 4 of gathering liquid, drives the inside remaining additive of conveyer pipe 2 and drops to the collection liquid jar 4 bottom. The liquid collection tank 4 is made of transparent materials, and scale marks 42 are marked on the liquid collection tank 4, so that the quantity of the residual additives can be conveniently observed.
The bottom surface of the connecting pipe 3 is a funnel-shaped bottom surface 33, the gas injection holes 32 are arranged in a downward inclined mode, and meanwhile the inner diameters of the connecting pipe 3 and the liquid collection tank 4 are larger than the outer diameter of the conveying pipe 2.
When the additive metering pump is used, the metering pump 1 is started, the additive is added into the base oil, the metering pump 1 is closed after the addition is finished, and the quantity of the additive pumped out by the metering pump 1 is known. Then the opening and closing device 5 is closed, the air pipe 6 supplies air to the annular air cavity 31, the air is sprayed out through the air spraying holes 32, the additive remained in the conveying pipe 2 is swept to the inside of the liquid collecting tank 4, and the residual quantity is observed through the scale mark 42. The total pumping quantity minus the residual quantity of the metering pump 1 is the actual additive quantity of the additive.
The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made without departing from the gist of the present invention within the knowledge of those skilled in the art.
