Can the four work at the same time, can the travel be synchronized

The electric push rod is a new type of electric actuator, which is mainly composed of motor, push rod and control device. It can realize remote control and centralized control. The standard stroke of electric push rod is 100150200250300350400mm. The special stroke can also be designed and customized according to different application conditions. The electric push rod can be designed with different thrust according to different application load. Generally, the maximum thrust force can reach 10n-6000n, and the no-load running speed is 2.5mm-80mm/s. The motor driven push rod uses the 24 V / 12V DC permanent magnet motor as the power source to convert the rotary motion of the motor into linear reciprocating motion. Push a group of linkage mechanism to complete the switching work of damper, valve, gate and baffle. Using the electric push rod as the actuator can not only reduce the air supply device and auxiliary equipment required by the pneumatic actuator, but also reduce the weight of the actuator. Pneumatic actuator in the whole control operation process need to have a certain air pressure, although the use of small consumption amplifier, but accumulated over time, the gas consumption is still huge. Using the electric push rod actuator, when changing the control opening, it needs power supply. When the required opening is reached, the electric push rod actuator has obvious energy-saving advantages than the pneumatic actuator.

Two stretching together or more
Scaling together is OK, but not fully synchronized
There is an error in the expansion and contraction. In short, some go fast and some go slowly
This is caused by the starting problem of DC motor
When the extension is finished, the size is the same height
