Gear-shaped electric putter introduction and selection needs

First: the thrust of the gear-shaped electric push rod is about 1/4, if the full load is not enough, the input voltage can be increased.


Second: The maximum stroke of the telescopic tube does not exceed 7 meters, and generally it is best not to exceed 2.5 meters in order to maintain stability.


Third: When choosing, it is best to match the self-locking device to prevent the abnormal voltage from causing damage to the putter.


Fourth: Check whether the pressure on the side of the putter is balanced, and install a balancing device if necessary.


Fifth: the operating temperature should be controlled at 0-35 degrees so as to ensure the service life.

Structure and performance of small electric putter

1. Structure: Electric push rod consists of drive motor, coupling (DTX type), worm gear, worm (DTW, TDTW type), reduction gear (DT, TDT, DTZ type), screw, copper nut, guide sleeve, push rod , Slide seat, housing, internal adjustment limit switch and other parts, compact structure, flexible action, stable, reliable performance and easy installation.


2. Working principle: After the motor decelerates through the speed change mechanism, it drives a pair of screws and nuts to change the rotation of the motor into linear motion. The reverse and forward rotation of the motor is used to complete the push and pull actions, and the thrust and pull are equal. For example, through various lever rocker arms or connecting rods and other mechanisms, complex movements such as rotation and rocking can be completed. By changing the length of the lever arm, the force can be increased or the stroke can be increased.


3. Automatic overload protection device: There is an overload protection device in the push rod. When the stroke of the push rod reaches the limit position or exceeds a certain value of the rated thrust, the push rod automatically stops to achieve the overload protection function, so that the motor and components are not damaged; DTW , DTX, TDT, TDTW are also equipped with internal stroke adjustment device stroke. The stroke can be adjusted according to the needs of the user. The device is small in size, high in sensitivity, easy to adjust, and integrated with the putter, making the appearance of the putter more concise and beautiful.


Energy-saving advantages of electric actuators

From the perspective of energy saving, electric actuators have obvious energy saving advantages over pneumatic actuators. It is suitable for long-distance operation and is widely used in the opening and closing, material loading and unloading, flow control, etc. of dampers, valves, gates and other institutions in the power, chemical, metallurgy, mining, light industry, transportation, shipping and other departments. It has been used by more and more departments to replace the automatic devices of mechanical hands, hydraulic valves, and reduction gears.

Application of electric push rod in unloader

The widespread application of electric actuators is believed to be obvious to all. However, for each specific application of the electric putter, it may not be so clear. Today we will specifically look at the application of electric push rods in the unloader.


The main function of the electric push rod in the unloader is to provide power to the unloader. How does it work? Let's take a look together.


When the unloader is working, due to the extension operation of the electric push rod, it plays a certain role in pushing the drive rod. Under the action of the driver, the frame is driven to perform the forward work. At this time, the nose also began to fall. While falling, it also plays a supporting role on the flat supporting roller group, so that the working surface of the tape is vertical, so that it can be in a very close fit with the lower edge of the machine head. Then put the material on the tape into the hopper, and the equipment will send the material to the designated place. When this unloading operation is completed, the electric push rod is retracted again, and it will also drive the drive rod to complete the corresponding work.


Using electric push rod as the power of the unloader, the equipment can not only have better stability, but also be very convenient to install. Unloading and conveying of materials can be achieved as long as the motor is forward and reverse


What is the composition of electric putter

The electric push rod is composed of a drive motor, a reduction gear, a screw, a nut, a guide sleeve, a push rod, a slider, a spring, a casing, a turbine, and a micro-control switch.


The electric push rod is a new type of electric actuator. The electric push rod is a new type of linear actuator mainly composed of motor, push rod and control device. It can realize remote control and centralized control. Electric push rods perform reciprocating movements within a certain range of strokes. Generally, the standard strokes of electric push rods are at 100, 150, 200, 250, 300, 350, 400 mm. Special strokes can also be designed and customized according to different application conditions. The electric push rod can be designed with different thrust electric push rods according to different application loads. Generally, the maximum push force can reach 6000N and the no-load running speed is 4mm ~ 35mm / s. The electric push rod is powered by 24V / 12V DC permanent magnet motor. Source to convert the rotary motion of the motor into a linear reciprocating motion. Push a set of linkages to complete the switching of dampers, valves, gates, baffles, etc. The use of electric push rods as the actuator not only reduces the air supply devices and auxiliary equipment required for the pneumatic actuator, but also reduces the weight of the actuator. Pneumatic actuators need a certain amount of air pressure during the entire control operation. Although amplifiers with low consumption can be used, the accumulation is large and the air consumption is still huge. With electric actuators, power is required to change the control opening, and power can no longer be provided when the required opening is reached. Therefore, from the perspective of energy saving, electric actuators have obvious energy saving advantages over pneumatic actuators. It is suitable for long-distance operation and is widely used in the opening and closing, material loading and unloading, flow control, etc. of dampers, valves, gates and other institutions in the power, chemical, metallurgy, mining, light industry, transportation, shipping and other departments. It has been used by more and more departments to replace the automatic devices of mechanical hands, hydraulic valves, and reduction gears.

Linear actuators for small electric actuator manufacturers in the automotive industry

Miniature electric linear actuators are used in a variety of ways in the car industry. In general, a power source like an electric motor is connected to a simple machine, typically a screw. Power source rotates the screw. A bolt or nut connected to the screw is fastened to the actuator of the body to prevent it from also rotating. Movement is converted into energy when the nut is along the length of the screw. In deciding what kind of implementing agency your car project needs, electric actuator manufacturers should think about the specific use procedures, which are to be used, and need to think about speed and strength.


Thanks to their simple mechanical movements, such as screws or shafts in energy conversion, linear actuators, so that everyone has the possibility to manipulate the trunks of windshield wipers, kickstands motorcycles and elevators or car or truck bed covers. Linear actuators are commonly used in car audio systems. There are many uses for cars with linear actuators, to be able to find anything, it is necessary to position from head, to move and move forward or backward, from side to side.


Linear actuators can find cars in most chapters. Under the hood, linear actuators are used for some applications, including controlling the throttle to adjust the engine speed, and at idle. In the exhaust system, a linear actuator controls the fuel vapor flow between the emission system and the intake manifold. Without some type of linear drive, power windows and door locks will not function properly. As long as the mission requires lifting, adjusting, tilting, pushing or pulling, the linear actuator has a braking system that may cause multiple use procedures under the hood, on the door or car. Linear actuators are also found, such as motorhomes, motorcycles and all-terrain vehicles, touring cars.


Matters needing attention in the running-in process of electric push rods and possible situations

The use of new electric actuators has a new running-in period just like driving a car. Only when the man and the machine are combined can better results be achieved.

(1)  Strictly guarantee the normal cooling of natural gas engines, and it is strictly forbidden to operate under abnormal cooling conditions (such as lack of water, excessively high or low water temperature, etc.). The cylinder liner can guarantee its normal working condition only under normal cooling conditions. Use qualified cooling water, and add an appropriate amount of rust-proof emulsion in the cooling water to prevent serious scale and cavitation.

(2)  Ensure that the air intake is clean and prevent sand, dust and harmful chemicals from entering the cylinder, so as not to cause severe wear or corrosion of the cylinder.

(3)  Natural gas fuel should be purified to prevent more harmful substances from entering the cylinder, which will cause corrosion and abrasion to the cylinder.

(4)  Avoid starting at low temperature and running at idle for a long time.

(5)  Do the initial running-in operation of the new machine and overhaul machine. Although the cylinder liners and piston rings of the new and overhaul machines have high machining accuracy and surface roughness, from the microscopic surface, it is inevitable that there are uneven machining marks. During the initial operation, the direct contact between the micro-protrusions on the relatively moving surface causes metal to directly contact with each other, making it difficult to form an oil film and causing dry friction. Under this condition, running at high speed directly under load will inevitably cause severe wear and tear, even scratching, 'cylinder biting'. Therefore, the natural gas engine must run in during the initial operation.


The so-called running-in process is to allow the natural gas engine to run for a certain period of time under no-load, low-speed and part-load conditions, so that the cylinder liner and the piston ring are `` matched '' with each other to eliminate surface unevenness and gradually form a film that is conducive to the establishment of oil Oil wedge shape. Improve lubrication conditions. A well-run natural gas engine can greatly reduce the wear of the cylinder liner during normal operation and increase its service life. It should be noted that when the natural gas engine has undergone the running-in process before leaving the factory, it is no longer necessary to use it. This process takes a long time.
