Example Embodiment

[0021] The present invention will be further described below in conjunction with specific embodiments.

[0022] Such as figure 1 Shown is a pressure regulation system for a hydraulically driven air conditioner in a crane control room, which includes a hydraulic pump 1, a proportional distribution valve 2, an electromagnetic control valve 3 (the electromagnetic control valve 3 includes an overflow valve 10 and a throttle valve 11), an air conditioner Motor 4, coupling 5, air conditioning compressor 6, swing buffer valve 7, swing motor 8, oil return tank 9, air conditioning control unit 12. The oil outlet of the main engine hydraulic pump 1 is connected to the oil inlet of the proportional distribution valve 2. After the oil is discharged from the proportional distribution valve 2, it is divided into two ways, one way through the hydraulic pipeline and composed of the overflow valve 10 and the throttle valve 11. The solenoid control valve 3 is connected to the air conditioner motor...

Abstract

The invention discloses a pressure regulating system of a hydraulically driven air conditioner in a crane control room. The oil outlet of the hydraulic pump of the main engine is divided into two paths through a proportional valve, and one path is controlled by an electromagnetic system composed of a hydraulic pipeline, an overflow valve and a throttle valve. The valve is connected with the air conditioner motor, and the air conditioner motor drives the air conditioner compressor to run through the coupling, and the electromagnetic control valve is adjusted and controlled in real time by the air conditioner control unit according to the collected values ​​of the pressure sensor and temperature sensor; the other way is through the hydraulic pipeline, The swing buffer valve is connected with the swing motor. The control valve composed of overflow valve and throttle valve is connected with the control unit to protect the pressure of the air conditioner motor, automatically adjust the pressure, and realize the stable operation and normal protection and cut-off of the air conditioner system. The air conditioner motor is connected to the air conditioner compressor through a coupling, which drives the air conditioner compressor to run stably and realizes the cooling performance of the air conditioner.

Description

technical field [0001] The invention relates to the technical field of air conditioners for cranes, in particular to a pressure regulating system for a hydraulically driven air conditioner in a crane control room. Background technique [0002] Generally, the upper part of the crane has no power (such as engine, motor, etc.). At present, the air conditioner used in the upper part of the crane generally chooses hydraulic drive. The existing pressure oil of the upper hydraulic system is used to switch through the electro-hydraulic valve to drive the air conditioner. The motor rotates, and then drives the belt pulley to rotate, and the belt rotates to drive the air conditioner compressor to rotate, thereby realizing the cooling function of the air conditioner compressor. [0003] The hydraulically driven air conditioner is connected in series in the hydraulic oil circuit of the main engine. When the engine speed of the main engine fluctuates suddenly, it is easy to cause sudden ...
