Due to the settlement of the hydraulic system, in order to achieve re-leveling, the hydraulic cylinder will be restarted repeatedly after a period of time, causing noise pollution; causing pollution of the sound source, especially at night in the dead of night, particularly harsh, seriously affecting the sleep of the elderly and children - no Mute
Hydraulic Wuhan home Villa Elevator relies on oil pump to work, ball valve adjusts oil quantity to achieve speed regulation, can't really realize VVVF frequency conversion speed regulation, high energy consumption, power consumption is about 3 times that of traction type household villa elevator - no energy saving;
The hydraulic household villa elevator is not equipped with ARD self-rescue device. The so-called power-off automatic leveling function promoted by the manufacturer is actually relying on the oil pump to release the pressure and pressure to make the car slowly descend to the bottom floor. It is impossible to open the door automatically, and it is necessary to manually open the door manually, especially the elderly. And the child can not help themselves, and the operation is also very inconvenient in wheelchairs, can not really achieve power failure near the leveling, automatically open the door to release people - can not really achieve power outages;
The speed is slow, the speed is generally only 0.3M/S or less, the energy saving effect is poor, the running efficiency is low;
The screw type household villa elevator uses the electric motor as the power source. The motor is connected with the nut through the belt, and the nut tooth pattern is engaged with the screw tooth pattern. When the motor is working, the driving nut moves on the screw rod, thereby driving the car to move up and down. .
