Technical Field

[0001] The utility model belongs to the technical field of variable frequency pumps, in particular to a combined supporting device for an oil and gas recovery variable frequency pump. Background Art

[0002] A variable frequency pump is a machine that transports liquids or pressurizes liquids. It transfers the mechanical energy of the prime mover or other external energy to the liquid to increase the energy of the liquid. It is mainly used to transport liquids including water, oil, acid and alkali liquids, emulsions, suspensions and liquid metals.

[0003] The power required for the variable frequency pump to transport liquid is provided by the drive motor. The pump body and the drive motor will generate high temperature after long-term high-speed rotation. The traditional heat dissipation method is to let it contact with the air and dissipate heat naturally. However, this heat dissipation method is inefficient, resulting in heat accumulation and making the variable frequency pump unable to work normally. Utility Model Content

Then, the bellows is pushed onto the auxiliary connecting plate, and the pull plate is rotated to make the card block disengage from the card slot, so that the spring rebounds and pushes the limit block to move, thereby fixing the bellows through the limit blocks on both sides of the auxiliary connecting plate to prevent the bellows from sliding and deviating. The rotating motor will rotate the fan blades, thereby blowing air from the vent to the drive motor through the fan blades, accelerating the dissipation of heat on the drive motor, and avoiding high temperature causing the pump body to fail to work normally.

[0013] 2. The combined supporting device for the oil and gas recovery frequency conversion pump is provided with a positioning block, a positioning groove, a first threaded hole, a second threaded hole, a hook plate, a torsion spring and a fixing rod.
