Abstract
The invention provides a variable frequency pump device with a three-phase motor. The variable frequency pump device comprises the three-phase motor, a magnetic variable speed device and steering pump, wherein the three-phase motor drives the steering pump by virtue of the magnetic variable speed; the three-phase motor and the steering pump are arranged on a same bottom plate; the part, corresponding to the magnetic variable speed device, of the bottom plate is of an inward concave structure; a connecting base is arranged between the bottom of the steering pump and the base; the connecting base is fixed on the base by virtue of a bolt; the inward concave structure of the base is provided with a bolt hole; the base is fixed by virtue of a bolt; and a shock absorption structure is arranged between the steering pump and the connecting base. The variable frequency pump device provided by the invention has the following characteristics: the three-phase motor and the steering pump are fixed on the same base, so that a torque force generated by the steering pump in the operation process acts on the base and cannot directly influence the three-phase motor; by virtue of the design of the shock absorption structure, the steering pump has higher stability and less possibility of being damaged during the operation process.
Description
Technical field
The present invention is that a kind of three phase electric machine drives the device that the magnetic speed changer is controlled steering pump, is applicable to the adjustable steering pump of lift.
Background technique
Present motor, steering pump all are split type designs, because the needs that use often will add a magnetic speed changer between motor and steering pump, by the adjusting of magnetic speed changer realization to rotating speed.But the overall structure more complicated, the installation of three equipment and use are all more loaded down with trivial details, in fixing process, if three equipment concentricitys are bad, also cause easily the damage of magnetic speed changer.
In " a kind of three phase electric machine frequency conversion magnetic variation speed variator " that the claimant applies on the same day, provided a technological scheme that solves this technical problem, but because the two ends of magnetic speed changer are fixed by flange and three phase electric machine, steering pump respectively, requirement to flange is higher, particularly in the steering pump running, the torsion that steering pump produces will directly be married again on the three phase electric machine, and this causes the problem of poor stability with regard to making easily three phase electric machine bear excessive torsion.Based on the problems referred to above, also need to design a kind of variable frequency pump device that can resist three phase electric machine, steering pump torsion of generation in running.
Summary of the invention
The purpose of this invention is to provide a kind of variable frequency pump device that can resist three phase electric machine, steering pump torsion of generation in running.
Purpose of the present invention is come specific implementation by the following technical programs:
A kind of three phase electric machine variable frequency pump device, comprise three phase electric machine, magnetic speed changer and steering pump, described three phase electric machine drives steering pump by the magnetic speed changer, described three phase electric machine and steering pump are installed on the same base plate, and the position of corresponding described magnetic speed changer is made as the structure of indent on described base plate, be provided with connecting base between the bottom of described steering pump and the base, described connecting base is bolted on the base.
Have bolt hole on the structure of the indent on the described base, by bolt described base is fixed.
Further design is to be provided with shock-damping structure between described steering pump and connecting base.
The innovative design of the technical program is, the present invention has realized three phase electric machine and steering pump are fixed on the same base, can make twisting force that steering pump produces in operation process on base, can directly not exert an influence to three phase electric machine, and the design of the shock-damping structure bottom steering pump, can make steering pump in the process of running, have larger stability, be not easy to damage.
Description of drawings
The below is described in further detail the present invention with embodiment with reference to the accompanying drawings.
Fig. 1 is the structural drawing of the described three phase electric machine variable frequency pump of embodiment of the invention device.
Embodiment
As shown in Figure 1, the described three phase electric machine variable frequency pump of embodiment of the invention device, comprise three phase electric machine 1, magnetic speed changer 2 and steering pump 3, described three phase electric machine 1 drives steering pump 3 by magnetic speed changer 2, described three phase electric machine 1 and steering pump 3 are installed on the same base plate 4, and the position of corresponding described magnetic speed changer 2 is made as the structure 5 of indent on described base plate 4, is provided with connecting base 6 between the bottom of described steering pump 3 and the base 4, and described connecting base 6 is bolted on the base 4.
Have bolt hole on the structure of the indent on the described base 4, by bolt described base is fixed.
Further design is to be provided with shock-damping structure 7 between described steering pump 3 and connecting base 6.
The innovative design of the technical program is, the present invention has realized three phase electric machine and steering pump are fixed on the same base, can make twisting force that steering pump produces in operation process on base, can directly not exert an influence to three phase electric machine, and the design of the shock-damping structure bottom steering pump, can make steering pump in the process of running, have larger stability, be not easy to damage.
