Abstract

The utility model discloses a drive device of a frequency variation control plunger pump. A plunger pump oil supply drive mechanism of the prior art adopts a common motor as power, the structure is more complicated, and the oil capacity change can not be controlled in time. The drive device of the frequency variation control plunger pump adopts a drive way that a frequency variation motor directly drives a speed reducer worm and a plunger pump by a speed reducer. The drive device of the frequency variation control plunger pump comprises the frequency variation motor, the speed reducer, a coupling, a special worm speed reducer of the plunger pump and a high-pressure plunger pump and forms a drive chain of the frequency variation motor, the speed reducer, the coupling, the special worm speed reducer of the plunger pump and the high-pressure plunger pump. The utility model controls the rotating speed of the frequency variation motor by changing the frequency of the frequency variation motor to achieve the aim of controlling the oil supply capacity. The application for obtaining different oil output in different time just by designing the running program reduces cost and energy consumption.

Description

A kind of transmission device of VFC plunger pump
Technical field
The utility model relates to the lubricated and leak-stopping technology of plastic banbury mixer in a kind of plastics gel equipment, particularly relates to the control transmission device of a kind of plunger-type fuel pump of plastic banbury mixer.
Background technique
In plastics gel operation process, the circulation of plunger pump in the banbury is supplied with high pressure oil incessantly continuously and is provided lubricated for the leak-stopping copper ring of stirrer, mixes at plastics that this high pressure oil also has extruding to promote the leak-stopping copper ring in case the effect of leak-stopping material in the process.The plunger pump fuel feeding driving mechanism of prior art adopts common electric machine to be used as power, adding connecting rod drives, ratchet structure by the worm-wheel shaft core, or provide an eccentric wheel by not holding at the bar of drive part, its controlling rod with one group of connecting rod rocking arm and pump is linked together, pass to motion up and down of bar, utilize different pin-and-holes position to change the crank-swinging angle, thereby change oil pump bent axle reciprocal time in the unit time and change oil pump capacity, such structure is comparatively complicated, can not in time control oil mass again and change, can not adapt to the needs of banbury.
Summary of the invention
In order to overcome the deficiencies in the prior art, guarantee that the plastic banbury mixer of plastics gel equipment can constantly obtain the fuel delivery of needs in process of production, need control the adjusting of oil mass by a kind of high-pressure plunger pump, with the process that guarantees to carry out gel in the plastics banburying production process.In order to obtain the control gear that an operation under the steady state could guarantee the fuel delivery size, the transmission device that a kind of VFC plunger pump is provided is the purpose of this utility model place, the technical solution of the utility model is to adopt a kind of variable-frequency motor, the kind of drive by direct gearing speed-reducer worm screw of speed reducer and plunger pump, control and change electric machine frequency, constantly regulate crankshaft revolution, design working procedure, follow procedure can obtain the application wheel of different oil pump capacity at different time, reduce cost, reduced energy consumption.The technical solution of the utility model is to come specific implementation by following technical measures: a kind of transmission device of VFC plunger pump, it is characterized in that it is made up of special-purpose worm reducer of variable-frequency motor, speed reducer, coupling, plunger pump and high-pressure plunger pump, wherein: described variable-frequency motor is special-purpose variable-frequency motor, be the operation power source of plunger pump, generally select the vertical special-purpose variable-frequency motor of AC of 0.75KWx4P model for use; Described speed reducer adopts gear reduction unit, connects with variable-frequency motor; Described coupling adopts elastic coupling flexible coupling; The special-purpose worm reducer of described plunger pump is made up of worm screw, bearing baffle, deceleration body, worm gear, bolt, bearing cover, oil sealing, bearing and worm-wheel shaft core, wherein: the spindle nose that goes out of described worm-wheel shaft core is a crankshaft structure, makes pump oil power with movable connection of the piston head of plunger pump; Worm gear cooperates with worm screw, is installed in the deceleration body, and the Partner of worm screw is installed bearing, and bearing cover is locked with bolt and deceleration body.Worm screw (initiatively) driving end is installed behind the bearing more fixedly oil sealing, plays seal action, bearing baffle is locked with bolt and deceleration body again.Special-purpose variable-frequency motor is with after speed reducer axially connects, again by coupling with worm shaft to connection, the Transmitted chains of formation variable-frequency motor-speed reducer-coupling-plunger pump special use pot bar retarder-high-pressure plunger pump.
The fuel feeding control source that good effect of the present utility model is to adopt variable-frequency motor to make plunger pump, the mode of direct driving ram pump worm reducer, control the rotating speed of variable-frequency motor by the frequency that changes variable-frequency motor, reach the speed of crankshaft of control worm-wheel shaft core, the frequency that control plunger pump piston head moves up and down reaches the purpose of controlling fuel delivery.As long as design working procedure, obtain the application of different oil pump capacity at different time, reduce cost, reduced energy consumption.
