Lift Rod application and undesirable phenomenon of electric push rod

Application selection
At present, the application of electric push rod is more and more, followed by many problems of electric push rod, during which many problems can be prevented, for example, the electric push rod is overloaded for a long time, and the lateral force is too large, the working system cannot wait. In order to avoid troubles when we apply the electric putter in the future, we need to know how to choose the right Electric putter.
First: the application temperature of electric push rod must be within its regulated range. If it is special, it should be clarified in advance.
Second: When the stroke is greater than 800mm, the length of the elastic tube should be added, and when the stroke is greater than 300mm, the stability of the electric push rod should be considered.
Third: balance the lateral force of the push rod to ensure that the electric push rod only accepts radial force when running.
Fourth, check whether self-locking is required. For more information, consult your local engineer.
Fifth: the working system of the electric push rod trapezoidal tooth screw is usually 25%. For full load, if not, it can be improved appropriately. The working system of the ball screw is 100%.
The above are some questions that should be paid attention to when selecting electric push rod. If you are choosing a suitable electric push rod, you must pay attention to some questions.

Undesirable phenomenon
DC electric putters are more common in the market, because DC electric putters are used in various fields such as electric dental chair, electric sofas, multifunctional operating beds and cleaning sanitation vehicles.
Many electric push rods in our country have been stopped by the switch of stroke alone. The transmission torque of electric push rod clutch can play a certain overload maintenance. Because the travel switch in the electric push rod is aimed at simple failure, especially in humid environment, and the torque error caused by clutch conditioning transmission is relatively large, therefore, it often leads to the situation that the stop position is not accurate enough, and the maintenance of overload is not reliable, and bad phenomena such as burning out the motor or damaging the transmission parts often occur, the noise of the clutch when it is out of overload maintenance will often be out of range.
Originally, the electric push rod was mainly used to roll into reciprocating linear motion by using the vice of Spiral. Therefore, compared with the electro-hydraulic push rod and cylinder, it is much cheaper in terms of cost, it can also save operating expenses and energy consumption.
Therefore, electric putters are widely used in mining, chemical industry, ships, electric power, machinery manufacturing and other professions. However, SPM type electric push rod does not need limit switches and clutches, so all the bad phenomena mentioned above will not happen on this electric push rod, the structure of all SPM-type electric push rod is relatively simple. Although it is simple to produce and manufacture, it is absolutely reliable in application. Only by installing an explosion-proof motor on this electric push rod, it can immediately transform into an explosion-proof electric push rod, so we can call it a comparative new electric push rod.
