Problems solved by technology
[0002] The existing hydraulic system in front of the furnace is mainly a manual hydraulic system, and its disadvantage is that the operator must manually operate the hydraulic valve table in the operating room to realize the work of each furnace front mechanism.
As a result, it is impossible to accurately and timely respond to the on-site working conditions, which has a certain impact on the accuracy of operations and emergency operations in emergencies
After the working pressure and flow rate of this kind of manual operating system are set during debugging, the workers cannot make corresponding adjustments according to the working conditions, which will easily lead to excessive system impact and other phenomena, which will directly affect the service life of the equipment in front of the furnace.

Embodiment
[0027] The system of the present invention is equipped with a pumping station and two operating consoles, and one pumping station plus two operating consoles controls two iron ports. The volume of the hydraulic oil tank of the pumping station is 2600L. The accessories of the hydraulic oil tank include: heating device, cooling device, oil return filter device, temperature sensor, liquid level sensor, pressure sensor and other components.
[0028] The main oil pump motor unit 2 is composed of three groups of oil pump motor groups, each group of oil pump motors includes a 75KW motor, a 125ml displacement servo feedback variable plunger pump, and is equipped with a pressure relay, a safety valve and a hydraulic pressure control system with two stages of pressure control. valve group.
[0029] The control mode is divided into four types: normal mode, adjustment mode, inspection mode and abnormal mode.
[0030] Normal mode: The equipment can be operated according to the normal acti...

The invention provides an automated stokehole hydraulic control system. The control system comprises a hydraulic oil tank and accessories, a main oil pump generator unit, a circulating oil pump unit, a hydraulic control valve platform and hydraulic pipelines, wherein the hydraulic oil tank and accessories are connected with the main oil pump generator unit and the circulating oil pump unit; the hydraulic oil tank and accessories as well as the main oil pump generator unit are connected with the hydraulic control valve platform through the hydraulic pipelines; the hydraulic oil tank and accessories, the main oil pump generator unit, the circulating oil pump unit and the hydraulic control valve platform are connected with an electric control system; and the electric control system is provided with a PLC (programmable logic controller). In the invention, according to the work pressure and flow of an automatic work condition regulating system, the interlocking of actions among various work mechanism equipment in front of the furnace is realized, and the spot sudden situations can be effectively treated in time, thereby avoiding the loss, reducing the working capacity of spot workers and greatly improving the stokehole work efficiency and safety class.
Description
technical field [0001] The invention relates to an automatic control system, in particular to an automatic furnace front hydraulic control system. Background technique [0002] The existing furnace front hydraulic system is mainly a manually operated hydraulic system, and its disadvantage is that the operator must manually operate the hydraulic valve table in the operating room to realize the work of each furnace front mechanism. This kind of operation mode makes the position of the operator relatively fixed and the angle of view is narrow. At the same time, personnel must be arranged at the furnace mouth to observe the on-site working conditions and contact the operator at any time to guide the operator to operate. As a result, it is impossible to accurately and timely respond to the on-site working conditions, which has a certain impact on the accuracy of the operation and the emergency operation in case of emergency. After the working pressure and flow rate of this kind ...
