Oil Immersed Low Noise Hydraulic Power Unit for Home Lift with Manual Pump

Core Advantages of Low Noise Elevator Hydraulic Power Unit 

 1. Extreme noise reduction, suitable for harsh environment  1. Multiple noise reduction structure design Oil-immersed motor + helical rotor pump + double-layer sound-proof shell + damping base are used to block mechanical vibration noise and fluid impact noise. The running noise is as low as 42 ~ 45dB, which is far better than 65 ~ 75dB of ordinary pump station. There is no interference in the surrounding installation of machine room, villa basement, ward and hotel guest room. A hydraulic pulsation damper is added to eliminate the abnormal noise caused by the impact of the oil circuit.Start and stop without sharp noise. 

2. Variable frequency speed regulation noise reduction from the source The frequency conversion motor automatically adjusts the speed according to the load, runs at low speed with no load, avoids the continuous noise generated by the constant operation at full frequency, and further reduces the noise under low load condition at night, which meets the night silence standard in residential areas.  Second, the operation is smooth, and the comfort of the elevator is greatly improved.  Damping buffer valve group + flow fine control, lift car lifting without shaking, setback, impact shaking, leveling accuracy ± 3 mm;The ride experience of the elderly, patients and high-end residential buildings is significantly better than that of the conventional hydraulic pump station.  Third, energy saving and consumption reduction, long-term use cost is lower  The variable-frequency variable pump supplies oil on demand, operates with light load and low power consumption, and its overall energy consumption is 28% -35% lower than that of the ordinary fixed-frequency pump station; it automatically unloads in standby mode, and the oil temperature rises slowly, so it saves additional oil cooling equipment, reduces the input of air conditioning and heat dissipation devices in the computer room and the expenditure of electricity, and the economy of long-term high-frequency use is outstanding.  Durable structure, low failure rate and simple maintenance  An integrated valve body, an oil tank
