What is the primary purpose of piping in the machine room?

The primary purpose of piping in the machine room is to transport hydraulic fluid in hydraulic elevator systems. In hydraulic elevators, the movement of the elevator car is achieved through the use of hydraulic fluid that is pumped into a cylinder, which then moves the piston and raises or lowers the car. The piping system is essential for conveying this fluid from the pump and reservoir to the cylinder and back, ensuring efficient operation of the elevator.

This function is critical because the hydraulic fluid acts as the medium that facilitates the motion of the elevator. Proper design and installation of the piping system are necessary to ensure that pressure is maintained, leaks are avoided, and the overall elevator system operates smoothly and safely. The piping must also withstand the pressures and temperatures typical in hydraulic systems, contributing to the overall safety and reliability of the elevator operation.
