Abstract
The invention discloses a hot oil pump shaft cooling sealing device which comprises hot oil, a pump shell, a bearing, a shaft and a seal. The hot oil pump shaft cooling sealing device is characterized in that a shaft seal (4) is arranged between a self-lubricating bearing of the shaft (5) and a ball bearing (7). A pump shaft (5) is provided with a shaft blade groove (9) which is arranged inside a blade groove cavity of the pump shell (6), and a shaft rotating band rotates the blade groove to push partial hot oil (1) leaked by a self-lubricating bearing (2) to an oil outlet (10) which is communicated with fluid of a cooler (11). After the hot oil is cooled, the viscosity of the hot oil is improved; the hot oil flows back to a shaft cooling cavity in a circulatory mode for cooling the seal (4) and the shaft, the hot oil enters the blade groove cavity (16) for circulation through an oil inlet (17). The shaft cooling cavity (3) shields heat of the hot oil so that a seal (4) is benefited for sealing under physical conditions of the low-temperature high viscosity hot oil and can achieve the sealing over the high-temperature low-viscosity hot oil.
Description
Technical field
The present invention relates to the hot oil pump of heat-conducting oil heating system, specific description is a kind of hot oil pump seal arrangement.
Background technique
Heat-conducting oil heating system is that conduction oil is directly heated, and carries out pump circulation by the high temperature heat conductive oil pump, the conduction oil after heating is transported to heat and standby with being installed with, then by get back to the hot oil oven heating with hot equipment oil outlet, forms heating system.Conduction oil is under high temperature is hot, viscosity is extremely strong far below water and permeability, the hot oil pump needle seal of prior art can not play the effect of sealing fully to the conduction oil under High Temperature High Pressure is hot, and always having that a small amount of conduction oil oozes out is the actual techniques problem that present high temperature heat conductive oil pump need to solve.
Summary of the invention
The present invention is exactly for the problems referred to above, and a kind of hot oil pump axis cooling sealing device is provided.
