Top-speed actuator

Abstract

The invention discloses a top-speed actuator. The top-speed actuator comprises a box body, a wiring groove, a contactor, a turbine, a worm, a base plate, a connecting gear, a motor, a speed reducer and a conversion control module box, wherein the inner side of the front end of the box body and the outer side of the rear end of the motor are fixedly installed, and the front end of the motor and the rear end of one side of the speed reducer are movably installed. According to the top-speed actuator, an alternating-current power supply which is convenient to obtain is utilized, a high-voltage direct-current motor with high driving efficiency and high speed is realized, moreover, under the driving of the high-voltage direct-current motor, the actuator can obtain extremely high valve opening and closing speed, the speed is 5-20 times that of a traditional actuator, and the actuator is called the top-speed actuator; and meanwhile, the speed of the electric top-speed actuator catches up with or even exceeds that of a pneumatic actuator, so that the pneumatic actuator can be replaced only from the aspect of the speed, then a compressed air station can be omitted, a tedious gas pipeline and a tedious electromagnetic valve are omitted, the equipment cost is greatly reduced, the environmental noise is also reduced, and the environmental protection and the health of staff are facilitated.

Description

technical field [0001] The invention relates to the technical field of electric equipment, in particular to an extreme speed actuator. Background technique [0002] Existing valve electric actuators usually use AC power, because AC power is the most widely available power source, and AC power can directly run the AC motor to provide power for the actuator. However, the efficiency of the AC motor is low, and most of the electric energy is converted into heat energy, which not only wastes energy, but also easily causes the AC motor to overheat and even burn out; the speed of the AC motor is also low, usually at the level of 1400 rpm. It also restricts the operating speed of the valve electric actuator. [0003] The existing valve electric actuators also use DC power supply, and the power supply voltage is usually DC24V, which requires the user to prepare a conversion device that converts AC power into DC power, which not only increases the trouble for the user, but also incre...

Problems solved by technology

[0005] The purpose of the present invention is to provide an extremely fast actuator to solve the low efficiency of the AC motor proposed in the above background technology, and most of the electric energy is converted into heat energy, which may easily cause the AC motor to be overheated or even burned. When using a DC power supply, the user needs to prepare It is better to convert alternating current into direct current conversion device, which increases the cost and the problem of low power
