Abstract
The utility model belongs to a kind of coke over machinery hydraulic emergency protective system, comprises motor (8) and quantitative oil pump (2), it is characterized in that connecting a unloading overflow valve (7) and an one-way valve (6) in the outlet of quantitative oil pump (2) with pipeline; The outlet pipeline of one-way valve (6) is connected with the Stress control hydraulic fluid port of accumulator stop valve (5) with two-way plug-in valve (3), unloading overflow valve (7), and accumulator stop valve (5) is connected with accumulator (4) filler opening; The drain tap of accumulator stop valve (5), two-way plug-in valve (3) control the oil return current-sharing oil sump tank (1) of oily oil return and unloading overflow valve (7).This model utility emergency response speed is fast, and structure is simple, and cost is lower.Adopt independent quantitative oil pump to save the main system energy, improve the energy storage capacity of accumulator, ensure that system pressure when power-off responds and flow, improve the reliability of system.
Description
Technical field
The utility model belongs to hydraulic protection system, and particularly a kind of Jiao is used for coke guide, charging car and the coke over machinery hydraulic emergency protective system without vapour switchboard power-off protection.
Background technique
Current existing coke over machinery hydraulic emergency protective system, most hand pump or diesel engine of adopting is protected as current failure emergency.Hand pump emergency system speed of response is slow, and diesel engine emergency system complicated structure, cost is higher.
Summary of the invention
The object of the invention is to overcome above-mentioned technical deficiency, provide a kind of fast response time, structure is simple, lower-cost coke over machinery hydraulic emergency protective system.
The technological scheme that the utility model technical solution problem adopts is: a kind of coke over machinery hydraulic emergency protective system, comprises motor and quantitative oil pump, it is characterized in that connecting a unloading overflow valve and an one-way valve in the outlet of quantitative oil pump with pipeline; The outlet pipeline of one-way valve is connected with the Stress control hydraulic fluid port of accumulator stop valve with two-way plug-in valve, unloading overflow valve, and accumulator stop valve is connected with accumulator filler opening; The drain tap of accumulator stop valve, two-way plug-in valve control the oil return current-sharing oil sump tank of oily oil return and unloading overflow valve.
The beneficial effects of the utility model are: this model utility emergency response speed is fast, and structure is simple, and cost is lower.Adopt independent quantitative oil pump to save the main system energy, improve the energy storage capacity of accumulator, ensure that system pressure when power-off responds and flow, improve the reliability of system.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, illustrate with embodiment.
Fig. 1 is coke over machinery hydraulic emergency protective system schematic diagram.
In figure: 1-fuel tank; 2-quantitative oil pump; 3-two-way plug-in valve; 4-accumulator; 5-accumulator stop valve; 6-one-way valve; 7-unloading overflow valve; 8-motor; P-pipeline.
Embodiment
Embodiment, with reference to accompanying drawing, a kind of coke over machinery hydraulic emergency protective system, comprises motor 8 and quantitative oil pump 2, it is characterized in that connecting a unloading overflow valve 7 and an one-way valve 6 in the outlet of quantitative oil pump 2 with pipeline; The outlet pipeline of one-way valve 6 is connected with the Stress control hydraulic fluid port of accumulator stop valve 5 with two-way plug-in valve 3, unloading overflow valve 7, and accumulator stop valve 5 is connected with accumulator 4 filler opening; The drain tap of accumulator stop valve 5, two-way plug-in valve 3 control the oil return current-sharing oil sump tank 1 of oily oil return and unloading overflow valve 7.Two-way plug-in valve 3 pipeline P is connected with the Hydraulic Main Ore-controlling Role of coke oven machine.
The system of this model utility is 7MPa, and energy storage pressure is 11MPa.Working procedure is, after motor 8 starts, drives quantitative oil pump 2 to operate, oil suction by coupling; Fluid, through unloading overflow valve 7 filler opening, enters into accumulator 4, as emergency fluid by one-way valve 6 and accumulator stop valve 5; The setting pressure of unloading overflow valve 7 is 11MPa, and its working pressure is controlled by one-way valve 6 oil outlet, and when accumulator 4 internal-filling liquid pressure reaches setting pressure 11MPa, unloading overflow valve 7 starts off-load, and one-way valve 6 is by disconnected for oil circuit envelope; Owing to there is the difference in areas of 17% in unloading overflow valve 7 pilot valve, when accumulator 4 pressure store slow releasing is to 9MPa, unloading overflow valve 7 stops off-load, and one-way valve 6 is opened, and quantitative oil pump 2 continues as the pressurising of accumulator 4 fuel feeding; Unloading overflow valve 7 from off-load to stopping off-load this process, complete the intermittent type Fuel injection system of an oil pump 2.When system emergency responds, electromagnet YH1 obtains electric, two-way plug-in valve 3 is opened, emergent fuel feeding path is through, accumulator 4 discharges pressure store, emergent fluid by the larger two-way plug-in valve 3 of negotiability by the road P supply the Hydraulic Main Ore-controlling Role of coke oven machine, after guaranteeing main system power-off, switchboard oil cylinder can complete the action that once commutates.
This model utility is compared with original hydraulic emergency system, and emergency response speed is fast, and structure is simple, and cost is lower.Adopt independent oil pump to save the main system energy, improve the energy storage capacity of accumulator, ensure that system pressure when power-off responds and flow, improve the reliability of system, receive praises from customers.
