Top Benefits Of Elevator Counterweight System And Design That You May Not Know
Elevator counterweight suppliers will share this article with you.
A counterweight is a weight that provides balance and stability of the mechanical system by applying opposing forces. The basic purpose of the counterweight is to make the lifted load more effective, save energy, and put less pressure on the lift.
Counterweights are mainly used for elevators, playground amusement devices and cranes. In this system, in order to prevent excessive balance on both sides, the expected load increase distance from the main support must be equal to the mass of the counterweight multiplied by the distance to the critical point. The size of the motor of an elevator counterweight is an important part of the elevator counterweight system.
Why is the motor size design of the elevator counterweight necessary?
The calculation of the size of the motor used to drive the elevator counterweight system is necessary. There are two methods for calculating the size of the motor: steady-state method and dynamic method. Steady state method and dynamic method. The steady-state method guarantees that the motor can move the unbalanced mass at an ideal steady-state speed. The guarantee of the dynamic method enables the motor to accelerate and decelerate the mass to the required rated speed.
In elevators, these two methods are usually used, because an important performance criterion of an elevator is that it can accelerate and decelerate within the required time. The steady state method is used to check the expected rated power of the motor. The dynamic method is used to ensure that the rated torque of the motor is sufficient to accelerate the motor within the necessary time. On the other hand, on escalators, since escalators do not start and stop as frequently as elevators, the only commonly used method is the steady-state method.
Benefits of using counterweight
Lifting weights becomes easier
The counterweight makes it very easy to raise and lower the car for the engine. Due to the counterweight, the motor does not require much force to move the car up or down. Assuming that the weight of the car and its contents is greater than the counterweight, the motor must lift the weight difference between the two and generate a little extra force to overcome the friction in the pulley.
Ensure elevator counterweight safety
In situations where safety is very necessary, counterbalance the elevator system. Since the force involved is smaller, the cable's pulling force is also smaller, which makes the elevator safer and the cable has a longer service life.
Ensuring energy efficiency
The engine needs a huge amount of energy to lift the car. The counterweight system reduces the energy required to lift the motor. Therefore, the motor uses less energy to increase the same distance of the car and consumes less energy. Therefore, if less energy is consumed, costs will be reduced and maintenance will be reduced.
Act as an additional energy source
The counterweight reduces the amount of braking the elevator needs to use. It is precisely because of the existence of this balancing force that a heavy-duty elevator car is easily pulled up, and on the way back, due to a balancing force to stop it, it will not fall to the ground. The counterweight elevator system makes it easier to control the car and prevents it from being forced downward.
