Oil injection system, method and device

Abstract

The invention provides an oil injection system, method and device, and relates to the field of mechanical automation control. The oil injection system comprises a parameter detecting module, a scanning module, an oil injection module, a flowmeter and a controller. The controller is electrically connected with the parameter detecting module, the scanning module, the oil injection module and the flowmeter correspondingly, and the controller is used for controlling the scanning module to operate to obtain label information of a target device when an oil temperature value and an oil pressure valuemeet the preset conditions, obtaining a target oil injection amount according to the label information, controlling the oil injection module to operate when receiving an opening instruction, and thencontrolling the oiling injection module according to the target oil injection amount and an actual oil injection amount. Product information is obtained through the scanning module, the target oil injection amount is obtained according to the product information, and at the same time, the actual oil injection amount is tracked to ensure that the actual oil injection amount is close to or the sameas the target oil injection amount; and meanwhile, the whole process is completely automatic, the oil injection efficiency is improved, and the accuracy of oil injection is guaranteed.

Description

technical field [0001] The invention relates to the field of mechanical automation control, in particular to an oil injection system, method and device. Background technique [0002] The compressors of the current air-cooled air-conditioning systems all need refrigeration oil (lubricating oil) to lubricate the rotating parts during operation. The multi-line system has a higher demand for refrigeration oil (lubricating oil) due to its one-to-many attributes and the characteristics of long connecting pipes. Therefore, in addition to the parts that come with the compressor, there are also It is necessary to add an appropriate amount of refrigeration oil to the compressor or its designated position (oil separator, etc.), that is, online oil injection. [0003] In the prior art, there are generally two oiling methods: manual oiling and simple machine oiling respectively, that is, according to the amount of oiling required by the machine model, manual weighing, and then manual fi...

Problems solved by technology

However, manual operation is prone to errors (especially when the same production line produces different models and the oil injection volume changes) and the efficiency is low

The simple machine oil injection system relies on manually setting the corresponding relationship between the model and the oil injection volume, and manually operating the oil injection machine. It is not a fully automatic oil injection system, which can improve accuracy and efficiency to a certain extent, but cannot realize the whole process of intelligent operation.
