Description

Technical Field

[0001] The utility model relates to the technical field of high-speed pumps, in particular to a cooling structure of an oil tank of a high-speed pump. Background Art

[0002] High-speed pumps are mainly used in the fields of petroleum and chemical industry, which have high requirements for pumps and need to maintain a large speed and pressure. Since the pump body and gears are flushed with oil to achieve lubrication and cooling effects when the high-speed pump is running at high speed, the oil in the oil tank will take away the heat of the pump body and gears in time, but the traditional oil tank is set in the gear box. The oil tank set in the gear box is not conducive to heat dissipation and cooling as the operating oil temperature rises, and it is very inconvenient to disassemble the gears when cleaning the oil tank.

[0003] In order to solve the above problems, the existing high-speed pump sets the oil tank outside. Although it solves the technical problems of poor heat dissipation and inconvenient cleaning of the built-in oil tank, there is still the problem of low heat dissipation efficiency of the oil in the oil tank, resulting in low cooling efficiency of the pump body and gears.

[0007] Preferably, a nozzle is provided at the bottom of the liquid outlet for spraying the coolant that absorbs heat to improve the heat dissipation efficiency of the coolant.

[0008] Preferably, the bottom of the coolant tank is provided with a plurality of heat dissipation fins which are longitudinally arranged and whose bottoms extend into the auxiliary tank.
