The concept of rated power is mainly as follows:
Rated power refers to the maximum output power that mechanical equipment can achieve, and the actual output power of mechanical equipment will not be greater than the rated power, which is different from electrical appliances. The rated power of an electrical appliance refers to the power when the electrical appliance works normally. Its value is the rated voltage of the appliance multiplied by the rated current.
If the actual power of the electrical appliance is greater than the rated power, it may damage the electrical appliance; If the actual power is less than the rated power, the electrical appliance will not work normally. In DC circuit, the product of rated voltage and rated current is the rated power of electrical appliances.
The concept of power is mainly as follows:
Power is the work done by an object in unit time, and power is a physical quantity that describes the speed of doing work. The shorter the workload, the greater the power value. The formula for finding power is that power is equal to the work time. Power means a physical quantity of how fast work can be done. The work done per unit time is called power, which is expressed by p, so power is equal to the scalar product of the acting force and the speed of the point of force on the object.
The concept of rated voltage is mainly as follows:
Rated voltage refers to the best voltage when electrical equipment works normally for a long time. Rated voltage is also called nominal voltage. When the working voltage of electrical equipment is higher than the rated voltage, it is easy to damage the equipment, but it cannot work normally when it is lower than the rated voltage.
The concept of rated current is mainly as follows:
Rated current refers to the current when electrical equipment runs at rated voltage and rated power. It can also be defined as the current that electrical equipment can work continuously for a long time under rated environmental conditions (ambient temperature, sunshine, altitude, installation conditions, etc.). ). The current of the electrical appliance during normal operation should not exceed its rated current.
The main uses of mechanical equipment are as follows:
Mechanical equipment is mainly used to replace manual work activities, which can reduce labor intensity and improve production efficiency. Mechanical equipment is the material and technical basis of enterprise production. As a modern production tool, it is widely used in all walks of life.
With the improvement of productivity, the technical condition of equipment plays a decisive role in the normal operation of enterprise production, product productivity, quality, cost, safety, environmental protection and energy consumption.
