Embodiment Construction
[0019] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0020] Such as figure 1 As shown, the aerator hydraulic control system in this embodiment includes a variable pump 2, an electric motor 1, a hydraulic motor 6, a reducer 7, an impeller 8, a reversing valve 3, and an oil tank 9. The variable pump 2 provides hydraulic pressure for the system, and the electric motor 1. The power output end is connected to the power input end of the variable pump 2. The hydraulic motor 6 has a power input end connected to the hydraulic output end of the variable pump 2. The reducer 7 is set at the power output end of the hydraulic motor 6. The impeller 8 is set at the speed reduction end. At the output end of the motor 7, the reversing valve 3 is used to control the flow of the variable pump 2, and the oil tank 9 is located on the hydraulic circuit composed of the variable pump 2 and the hydraulic motor 6. An ove...

A hydraulic control system of an aeration machine comprises a variable desplacement pump, an electromotor, a hydraulic motor, a reduction box, impellers, a change valve and an oil tank. A power output end of the electromotor is connected with a power input end of the variable desplacement pump, the hydraulic motor is provided with a power input end connected with a hydraulic pressure output end of the variable desplacement pump, the reduction box is arranged at the power output end of the hydraulic motor, the impellers are arranged at the output end of the reduction box, the change valve is used for controlling flow of the variable desplacement pump, and the oil tank is arranged on a hydraulic return circuit composed of the variable desplacement pump and the hydraulic motor. Compared with the prior art, the hydraulic control system has the advantages of adopting a high-pressure high-speed hydraulic system to reduce equipment volume; adopting a pump-controlled speed regulating system to enable speed to be adjustable; being capable of slowly running under majority of working conditions to save a large amount of electric energy; and adopting whole hydraulic control, enabling both the speed and the pressure to be accurately adjusted, and having the functions of automatic protection.
Description
technical field [0001] The invention relates to an aerator, which belongs to the technical field of sewage treatment equipment. Background technique [0002] At present, there are special oxygenation equipment for sewage treatment plants. Small sewage treatment plants are equipped with more than a dozen sets, and large sewage treatment plants are equipped with hundreds of sets. In order to improve the effect of sewage treatment, a large number of enterprises are developing sewage treatment related equipment, among which the aerator is also one of the key equipment. Due to the relatively large power of the aerator, the power of a small single machine is tens of kilowatts, and the power of a large single machine is hundreds of kilowatts. The aerator has become the main factor of high energy consumption in environmental protection equipment, which directly affects the operation of the sewage treatment plant. Cost and economic benefits, controlling the energy consumption of aer...
