The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in detail.
With reference to accompanying drawing 2, the lubricated feed system of hot-strip of the present utility model mainly is made up of water supply installation, fueller and blender.Water supply installation mainly is made up of parts such as the water pump 6, electromagnetism water valve 7, ratio electromagnetism water valve 8 and some the essential connecting lines that connect motor, valve, Pressure gauge, gauge tables; Wherein, the water pump 6 that is connected with motor is connected to electromagnetism water valve 7 by supply channel, and electromagnetism water valve 7 is connected with ratio electromagnetism water valve 8 by supply channel, is connected on the blender 5 by supply channel again.In use, profit mixed proportion is as required come the discharge of preset proportion electromagnetism water valve 8, and control water is accurately supplied with blender 5 in proportion.
Fueller mainly is made up of parts such as operating oil tank 1, oil pump 2, solenoid directional control valve 3, proportional flow control valve 4 and connecting line that some are essential, valve, Pressure gauge, gauge tables; Wherein, adopt the constant-pressure variable hydraulic pump with the oil pump 2 that is connected motor, oil in the connected operating oil tank 1 is transported in the connected solenoid directional control valve 3, be connected on the blender 5 by the proportional flow control valve 4 that is connected with solenoid directional control valve 3 again, in use, profit mixed proportion is as required come the flow of preset proportion flow valve 4, and control oil is accurately supplied with blender 5 in proportion.
The oil and the water that enter blender 5 in the ratio of setting evenly mix in blender 5, then oil water mixture are ejected into the surface of work roll equably by the jet pipe 9 that is attached thereto, and play the effect that breaker roll is lubricated and cools off.
In when work, water carries out contaminant filter by the filter 10 that is arranged between water pump 6 and electromagnetism water valve 7 pipelines, with the water of cleaning again passing ratio electromagnetism water valve 8 send into blender 5 in the ratio of setting.
Rolled lubricating oil is transported to the oil in the fuel reserve tank in the operating oil tank 1 by oil pump 2, oil in the operating oil tank 1 is forced into 6.0～8.0MPa by oil pump 2, and contaminant filter is fallen by two filters 10, the lubricating oil of cleaning is sent into solenoid directional control valve 3, and passing ratio flow valve 4 is transported in the blender 5 by the ratio value of setting again.Can select the quantity of oil pump during use according to the size of pressure fuel pump, the utility model is provided with two oil pumps 2, to guarantee to have enough oil pressure supplies.
Because the mixed proportion of rolled lubricating oil and water is respectively by proportional flow control valve 4 and 8 accurately controls of ratio electromagnetism water valve, and mix in the ratio that technological requirement is set, therefore, the clean oil water mixture that mixes is ejected into the surface of work roll equably by the nozzle on the jet pipe 9, and work roll is carried out lubricated well and cooling.
During work, nip behind the roll when the band steel, solenoid directional control valve 3 and proportional flow control valve 4 that control oil is opened are just opened the beginning fuel feeding, in order to avoid skidding when occurring being with steel to nip.In steel such as roll, solenoid directional control valve 3 and proportional flow control valve 4 that control oil is opened are closed.But electromagnetism water valve 7 and ratio electromagnetism water valve 8 that control water is opened are normally open, to guarantee having water to flow in the jet pipe 9, make it be in work under the normal temperature, avoid producing the high-temperature coking thing.
The utility model adopts the constant-pressure variable hydraulic pump to carry lubricating oil, has guaranteed the constant of proportional flow control valve inlet pressure, has improved the control accuracy of proportional flow control valve, and the control dead band is significantly reduced.The flow of water has guaranteed that rolled lubricating oil mixes in given ratio in blender fully with water owing to adopt the control of ratio electromagnetism water valve, avoids excessive or too small and lubricant effect initiation is not obvious or roll the skids problem of rolled lubricating oil ratio.
Automatically controlled part of the present utility model is except that motor, and all control power supplys and electric control element all use the safe voltage of DC24V, and the security that has improved system works has also been avoided staff's safety is threatened.Simultaneously, parts such as check valve commonly used, stop valve, flowmeter and pressure switch are installed on each pipeline, guaranteeing the normal operation of feed system, and be convenient to carry out as required various conversions and parameters such as the pressure of each feeder, flow are monitored.
The utility model is provided with filter 10 at each water pump of lubricated feed system and the exit of oil pump, to filter out the impurity in water or the oil, avoids each valve and jet pipe in the block system, influences the operate as normal of system.
The utility model also can be designed to integrated control valve piece with employed various valves in water supply installation and the fueller, with volume and the floor space that reduces whole system, and can realize concentrating and maintenance and the maintenance accurately controlling and be convenient to equipment of flow.
