Abstract
The invention discloses a method for adjusting the rotation speed of a centrifugal machine, relates to the technical field of centrifugal casting, and is characterized in that a frequency converter is connected to a motor of the centrifugal machine, so that the rotation speed of the motor is changed by changing the frequency of the frequency converter; and two belt pulleys of which the transmission ratio is 1:1 are driven by the motor for transmission, and the rotation speed set by the frequency converter is the required rotation speed, so that the rotation speed can be conveniently and accurately adjusted. The method can be applied to various places where similar production needs are required to be met, and brings great convenience to the field.
Description
Technical field
The present invention relates to the centrifugal casting technique field, is a kind of method of adjustment that is used for centrifuge speed of invention concretely.
Background technology
Centrifugal casting is the casting workpiece blank method that a kind of casting quality is reliable, machining blanks efficient is high.In present production process, be magnesium iron, or a lot of material such as copper alloy all adopts centrifuge to pour into a mould, but the rotating speed of centrifuge can't accurately be controlled in the centrifugal casting process.Can produce very big centrifugal force in the centrifugal casting process, the size of centrifugal force and rotating speed have very large relation, so according to the product structure characteristic, the adjustment centrifuge speed directly has influence on the quality of watering the product that outpours.In traditional casting process, centrifuge speed mainly through the transmission control of belt pulley, through changing rotating speed of motor, connects two belt pulleys that gearratio is not 1:1, has calculated gearratio, adjusts again.Such method control is cumbersome, and is difficult to accurately get hold of the size of rotating speed, can't read centrifuge speed; Operating data is very not directly perceived; Therefore often actual rotating speed and the theoretical rotational speed that produces is inconsistent, and the rotating speed that the result obtains is greater than or less than actual required, the product defectiveness that casting is come out; Cause casting wasted product, produce significant wastage.
Summary of the invention
In view of the defective that prior art exists, the purpose of this invention is to provide a kind of convenient, adjust the method for centrifuge speed rapidly, freely.
For realizing above-mentioned purpose, the present invention solves through following technical scheme: the method for adjustment of centrifuge speed is characterised in that on the motor of centrifuge, to connect a frequency converter, through changing the frequency shift rotating speed of motor of frequency converter.
The invention is characterized in that the driven by motor belt pulley rotates, adopting gearratio is two belt pulley transmission rotating speeds of 1:1, and how many rotating speeds frequency converter is provided with like this, is exactly required rotating speed, accurately convenient.
The present invention goes for each place that similar production needs, and is very easy to the needs in this field.
Description of drawings
Fig. 1 is an enforcement structure diagram of the present invention.
Mark shown in Figure 1 is following: 1, motor, 2, frequency converter
.
The specific embodiment
The method of adjustment of centrifuge speed shown in Figure 1 is characterised in that on the motor 1 of centrifuge to connect a frequency converter 2, the rotating speed of the frequency shift motor 1 through changing frequency converter 2.
The invention is characterized in that motor 1 drives belt pulley and rotates, adopting gearratio is two belt pulley transmission rotating speeds of 1:1, and then the rotating speed of frequency converter 2 settings is required rotating speed, and is accurately convenient.
Claims (2)
1. the method for adjustment of centrifuge speed is characterised in that on the motor of centrifuge, to connect a frequency converter, through changing the frequency shift rotating speed of motor of frequency converter.
2. the method for adjustment of centrifuge speed according to claim 1 is characterised in that the driven by motor belt pulley rotates, and adopting gearratio is two belt pulley transmission rotating speeds of 1:1, and then the rotating speed of frequency converter setting is required rotating speed.
