High-foaming rubber high-sealing oil pump gasket and production process thereof

Abstract

The invention relates to the technical field of sealing, and discloses a high-foaming rubber high-sealing oil pump gasket and a production process thereof. The high-foaming rubber high-sealing oil pump gasket is characterized in that a mixing structure comprises a first motor, a shell, a protection shell, a heating pipe, a feeding pipe, a fixing ring, a transmission shaft, stirring blades, paddle blades, a discharging pipe, a discharging valve, an extrusion pipe and a material guiding shell, wherein the protection shell is fixedly connected to the top end of the inner side of the shell, the inner side of the protection shell is fixedly sleeved with the heating pipe, one end of the heating pipe is fixedly connected with the material guiding shell, the top end of the material guiding shell is fixedly connected with the shell, and the bottom end of the material guiding shell and the bottom end of the shell are fixedly connected with the discharging pipe. According to the invention, by arranging the first motor, the transmission shaft, the stirring blades and the paddle blades, after natural rubber, nitrile rubber and chloroprene rubber are mixed more uniformly, rubber and additives are mixed better, and then produced gaskets are softer and good in strength, elasticity and oil resistance.

Description

technical field [0001] The invention relates to the technical field of sealing, and more specifically, the invention relates to a high-foaming rubber high-sealing oil pump gasket and a production process thereof. Background technique [0002] There are many kinds of sealing gaskets in the engine, coupled with the improvement of engine technology, some sealing materials cannot meet the sealing requirements, especially some sealing medium pressure is not large, low sealing surface pressure (such as small bolt torque and / or large deformation of mechanical parts ) always has the problem of low sealing reliability. [0003] The oil pump is the power source of the oil circulation in the engine lubrication system. The oil pump is installed at the lower part of the engine block. When it rotates, the oil in the oil pan is pressurized and discharged to the lubricating oil circuit. After being filtered by the oil filter, it enters the required lubricating parts. If the performance of ...

[0002] There are many kinds of sealing gaskets in the engine, coupled with the improvement of engine technology, some sealing materials cannot meet the sealing requirements, especially some sealing medium pressure is not large, low sealing surface pressure (such as small bolt torque and / or large deformation of mechanical parts ) part always has the problem of low sealing reliability

[0003] The oil pump is the power source of the oil circulation in the engine lubrication system. The oil pump is installed at the lower part of the engine block. When it rotates, the oil in the oil pan is pressurized and discharged to the lubricating oil circuit. After being filtered by the oil filter, it enters the required lubricating parts. If the performance of the oil pump decreases and the oil pressure decreases, it will seriously affect the normal operation of the engine. Secondly, in the existing high-foaming rubber, the foaming agent agglomerates during foaming, resulting in excessive foaming of the rubber after foaming. , the hardness and density are not up to standard, the closed cells will become joint cells, the micro cells will become small holes, and the phenomenon of collapse or failure to rise will also occur, which requires re-foaming, which in turn leads to high costs. Moreover, the existing Gaskets are generally made of natural rubber and additives, but natural rubber has poor oil resistance, and when used in an oil pump, the oil may leak
