Problems solved by technology

[0002] At present, the existing air coolers are basically driven by electric motors and hydraulic motors. The air coolers driven by electric motors are often burned due to high ambient temperature in summer, especially in some special occasions, such as explosion-proof occasions. The requirement of electricity is very strict, even not allowed, so the air cooler driven by hydraulic motor is already an inevitable product in social progress, but the existing air cooler driven by hydraulic motor has the following problems: 1. One-way rotation work 2. There is no speed regulation function, which will cause waste of wind energy
3. Difficult to clean up

[0031] Such as figure 1 , figure 2 and Figure 4 shown, when the air cooler employs figure 1 and figure 2 When the cooling system shown is driven, the output terminal of the PLC control system 2 transmits the analog signal to the servo valve 381 of the hydraulic control system 3, so that the flow through it is automatically adjusted according to the temperature change sensed by the temperature sensor 1, Further driving and adjusting the rotating speed of the hydraulic motor 42, thereby driving the synchronous rotation of the fan 5 installed on the output shaft of the hydraulic motor 42, that is, the wind cooler can automatically adjust its rotating speed according to the working environment temperature. And when the servo valve 381 is in the left position, the positive rotation of the hydraulic motor 42 can be realized, thereby driving the forward rotation of the fan 5 installed on the output shaft of the hydraulic motor 42, and when the servo valve 381 is in the right po...

[0035] Such as figure 1 , image 3 and Figure 4 shown, when the air cooler employs figure 1 and image 3 When the cooling system shown is driven, the output terminal of the PLC control system 2 transmits the analog signal to the three-position four-way electromagnetic reversing valve 382 and the proportional valve 392 of the hydraulic control system 3, not only adjusting the three-position four-way electromagnetic reversing valve 382 The automatic reversing operation of the proportional valve 392 can be automatically adjusted according to the temperature change sensed by the temperature sensor 1, and the automatic adjustment of the speed of the hydraulic motor 42 can be realized, so as to realize the automatic adjustment installed on the hydraulic motor. 42 The speed of the fan 5 on the output shaft realizes that the air cooler can automatically adjust its speed according to the working environment temperature. And when the three-position four-way electromagnetic reversin...

Abstract

The present invention discloses a cooling system and an air cooler with the cooling system. The cooling system comprises a temperature sensor, a PLC control system and a hydraulic control system. The temperature sensor transmits the sensed temperature change to the input end of the PLC control system. The PLC control system converts the input temperature change signal into an analog signal. The output end of the PLC control system transmits the analog signal to the hydraulic control system. The air cooler comprises a fan and a hydraulic motor. The hydraulic motor is driven by the cooling system to work. By means of the air cooler driven by the cooling system, the required fan rotating speed can be automatically regulated according to the temperature change of the area where the fan works, and therefore the function of automatically regulating the speed of the air cooler is achieved; meanwhile, the effects that the fan rotates in the forward direction to work and rotates in the backward direction to clean itself can be achieved.

Description

technical field [0001] The invention belongs to the field of engineering machinery cooling equipment, in particular to a hydraulic motor cooling system and a hydraulic air cooler. Background technique [0002] At present, the existing air coolers are basically driven by electric motors and hydraulic motors. The air coolers driven by electric motors are often burned due to high ambient temperature in summer, especially in some special occasions, such as explosion-proof occasions. The requirements for electricity are very strict, even not allowed, so the air cooler driven by hydraulic motor is an inevitable product of social progress, but the existing air cooler driven by hydraulic motor has the following problems: 1. One-way rotation work 2. There is no speed regulation function, which will cause waste of wind energy. 3. It is difficult to clean up. Contents of the invention [0003] In order to overcome the disadvantages of the above-mentioned prior art, the present inve...
