Intelligent temperature control system for hydraulic oil temperature of coke oven vehicle

Abstract

The invention provides an intelligent temperature control system for the hydraulic oil temperature of a coke oven vehicle. The intelligent temperature control system comprises a PLC control system, ahydraulic system and a pipeline. The hydraulic system comprises a temperature sensor (1). The intelligent temperature control system further comprises a pneumatic valve (12), an air compressor (7), afreezing type air drying device (9), an air pocket (10) and an air return pipeline. The temperature sensor (1) is arranged on an oil tank of the hydraulic system. The temperature sensor (1) sends a detected temperature signal to the PLC control system. The PLC control system sends the signal to control the cooling air electromagnetic valve (12) of an oil cylinder to be opened. Air enters the air pocket (10) through the air compressor (7) and the pipeline. According to the intelligent temperature control system, whole-course automatic control is achieved during operation of coke oven vehicles such as a coal loading vehicle, a coke pushing vehicle and a coke guide vehicle, the service life of hydraulic oil and the oil cylinder is prolonged, and residual air can be recycled.

Description

technical field [0001] The invention relates to the field of temperature control of coke oven vehicle hydraulic oil, in particular to an intelligent temperature control system for coke oven vehicle hydraulic oil temperature. Background technique [0002] In the coking process, coke oven vehicles are important equipment, all of which are mobile machines, and the hydraulic system is the main control unit of coke oven vehicles. However, due to limited conditions, there is no sufficient water source on the vehicle. At present, natural wind circulation is generally used in China to dissipate heat. Cools the hydraulic system, not very well. Due to the influence of the surrounding high temperature environment, it becomes a system heating device in summer instead, resulting in a high oil temperature in the hydraulic system, which seriously affects the production and operation. At the same time, the oil temperature hazard has a more serious impact on the hydraulic system. During cok...

Problems solved by technology

When the hydraulic oil liquid level is lower than the safe liquid level, completely stop the work of the heater provided by the invention to prevent unexpected situations. This method is only applicable to the control of the tensioning machine in the tensioning process to which the invention is applicable. temperature, but in the coking process that the present invention will be applied to, there is no sufficient water source on the car and the ambient temperature is above 80°C all the year round. It is difficult to stably provide feedback signals for coking process vehicles to achieve normal work;

[0009] The automatic transmission oil temperature control method in CN 109058441A relies on the automatic transmission oil temperature and flow, cooling water temperature and flow information combined with the heat exchange spectrum of the oil cooler stored in the engine control unit and the oil temperature for the efficient operation of the automatic transmission interval, to obtain the oil flow and cooling water flow that need to be controlled so as to achieve the purpose of precise control. Compared with the present invention, this invention needs to use the measurement of flow information to achieve the purpose of temperature control and cooling, and the device for measuring flow information is in the coke oven It is difficult to work stably during the operation of the vehicle, so this invention cannot solve the purpose of operating the hydraulic oil temperature control system on the coal charging car, coke pushing car, and coke guiding car of the coke oven to be solved by the present invention
