Problems solved by technology
The heat generated by friction between the dynamic and static rings of the double-end machine seal and the heat near the dynamic and static rings are mainly taken away by the natural flow formed by the temperature difference of the sealing liquid in different parts of the sealing liquid supply system, that is, the hot liquid rises, the cold liquid sinks, and heat exchange low efficiency
In addition, although some double-end machine seal shaft sleeves have spiral blades, which can properly assist in improving the heat transfer situation, the overall heat transfer efficiency is still low.
The sealing liquid supply system can satisfy

Embodiment Construction
[0047] As an advanced sealing liquid supply system, the complete set of sealing liquid hydraulic pump station has the functions of sealing liquid storage, forced circulation, cooling and pressure maintenance.
[0048] The present invention is further defined with specific embodiments below in conjunction with accompanying drawing:
[0049] Such as Figure 1-4 As shown, the sealing liquid hydraulic pump station complete set of equipment of the present invention includes a main circulation system (i.e. the main circulation loop), and the main circulation loop is that the sealing fluid in the oil tank 1 passes through the pipeline successively through the first filter (oil suction filter) 7, Gear pump 6 (including motor 4 and coupling 5), first one-way valve 9, first ball valve 103, double-end mechanical seal 21, second filter 12, first overflow valve 14, second one-way valve (hydraulic control check valve) 15, cooler 16, sight glass 17, get back to fuel tank 1 at last.

The present invention relates to the technical field of double-face mechanical seals, in particular to a complete set of sealing liquid hydraulic pump station equipment, including a main circulation circuit with a gear pump and a cooler, a pressure stabilizing bypass and a pressure measuring bypass connected to the main circulation circuit , so that the circulation equipment has the functions of storing sealing fluid, forced circulation, cooling and pressure maintenance, because the gear pump makes the sealing fluid circulate in the circulation equipment forcibly, and indirect heat exchange with the cooler when it flows through the cooler, fundamentally solves the problem The problem of low heat exchange efficiency of the existing sealing liquid supply system is solved; at the same time, the complete set of equipment of the sealing liquid hydraulic pump station not only maintains the characteristics of stable sealing liquid pressure, but also the sealing liquid pressure is easy to adjust, thus significantly improving the performance of double-end mechanical seals. service life and reliability.
Description
technical field [0001] The invention relates to the technical field of double-face mechanical seals, in particular to a complete set of sealing liquid hydraulic pump station equipment. Background technique [0002] As we all know, the function of the double-ended mechanical seal is to isolate the material in the confined space from the outside world, that is, to achieve sealing. The characteristics of its application are that there is a rotating shaft and the confined space has a certain pressure, temperature or contains solid substances. [0003] At present, double-end mechanical seals are widely used in the fields of chemical and chemical engineering, petroleum and petrochemical, pharmaceuticals, natural gas, pulp and paper, steel, and industrial and mining industries. For example, the stirred tank commonly used in chemical enterprises has a certain pressure and temperature inside the tank. The double-ended mechanical seal is installed on the stirring shaft (rotating shaft...
