Abstract

The invention relates to a worm gear and worm speed reduction type three-plunger reciprocating pump. The worm gear and worm speed reduction type three-plunger reciprocating pump comprises a motor (100), a coupling, a box (125), a speed reduction mechanism and a driving mechanism, wherein the speed reduction mechanism and the driving mechanism are arranged in the box (125). The motor (100) is a vertical motor and is arranged above the box (125). The speed reduction mechanism comprises a worm (120) and a worm gear (225). The worm (120) is vertically installed in the box (125) through a bearing. The upper end of the worm (120) is further connected with the motor (100) through the coupling. The worm gear (225) is connected with the driving mechanism and engaged with the worm (120). Compared with the prior art, the worm gear and worm speed reduction type three-plunger reciprocating pump has the advantages of being compact in structure, small in occupied space and the like.

Description

technical field [0001] The invention relates to a three-plunger reciprocating pump, in particular to a three-plunger reciprocating pump with worm gear and worm speed reduction. Background technique [0002] Three-plunger reciprocating pump is a kind of liquid conveying equipment that can obtain high pressure and large flow. Its conveying medium is extremely wide. Under the situation of energy shortage in the world today, three-plunger reciprocating pumps, as energy-saving products, are widely used in oil and gas field exploitation, petrochemical, coal chemical, heavy oil transportation, iron and steel metallurgy, urban pipeline network transportation and other industries. [0003] The three-plunger reciprocating pump is composed of a motor, a reduction mechanism, a drive end, a fluid end, and lubrication. Most of the reduction mechanisms currently used are belt reduction transmissions, and gear reduction transmissions are also used. The belt reduction transmission takes up...
