An intelligent ultra-low speed stepless speed regulation hydraulic energy-saving fan

Abstract

The invention belongs to the technical field of hydraulic energy-saving equipment, and relates to an intelligent ultra-low speed stepless speed regulating hydraulic energy-saving fan. Fan blades are mounted on a variable displacement motor, a mesh enclosure covers the fan blades, and the variable displacement motor is mounted on a base supporting system. A hydraulic system is connected with a control system which is provided with a wireless network interface and a wired network interface, and a variable pump is connected with a variable motor. A first one-way valve and a second one-way valve are in series connection and then are connected with the variable pump. An oil replenishing pump and a safety valve are both connected with an oil tank, and an overflow valve is connected with the oil tank. The motor is connected with the overflow valve and a fixed pressure reducing valve respectively, and a throttling valve is arranged between the fixed pressure reducing valve and the oil tank. A sensor and an operation display are both connected with the control system, a wireless remote control receiving unit is arranged at the bottom of a base supporting system, and the wireless remote control receiving unit and a wireless remote control sending unit constitute a wireless remote control unit. The intelligent ultra-low speed stepless speed regulating hydraulic energy-saving fan is simple in structure, scientific in principle, safe and reliable to use, little in energy consumption, good in energy-saving effect, low in cost, short in manufacturing cycle, and high in production efficiency.

Description

Technical field: [0001] The invention belongs to the technical field of hydraulic energy-saving equipment, and relates to an intelligent ultra-low-speed stepless speed-regulating hydraulic energy-saving fan, which can customize the rotation angle in the whole space, has an independent learning function, and can completely simulate natural wind. Background technique: [0002] At present, electric fans that use the rotation of blades to accelerate air flow, change local ambient temperature and humidity, and realize ventilation have become commonly used in people's daily life, office space, industrial and agricultural production, and even in instruments and meters because of their simple structure and low price. equipment. However, the electric fan cannot realize ultra-low-speed operation because of the motor, and cannot realize real indoor natural wind, nor can it realize the effect of indoor breeze blowing against the face. The existing so-called natural wind effect only all...

Problems solved by technology

Although the air supply range is expanded to a certain extent by using the swing head mechanism, the swing angle achieved by the loose air mechanism is either fixed (90° in general), or the swing range is limited, and can only be selected within a limited range, such as 40°- You can choose between 80°-120° or 50°-75°-100°; at the same time, the swing speed of the oscillating mechanism is fixed due to its structure, basically using the action of the connecting rod, and the electric fan oscillating plate swings left and right within the circumference Each once, a total of 6‐8rpm swing, hindering the realization of the real natural wind effect in the room
