Description
Technical field
The present invention is a kind of structure-improved of cooling system of wind generating set workpiece, specifically relates to a kind of improved device of wind power generator unit frequency converter water cooling system temperature control valve block.
Background technology
The wind power generator unit frequency converter water cooling system is to be installed in the wind-powered electricity generation unit generation cabin or in the tower tube, to the dispel the heat device of cooling of frequency converter internal heating element.This cooling system is in operation; Interface, pump entrance, temperature-sensing valve, electric heater, thermal resistance and the pressure measuring tie-in of the interface of turnover radiator, turnover frequency converter all are integrated on the temperature control valve block; Temperature-sensing valve can be changed the flow direction of coolant automatically through the temperature that detects coolant, and the control coolant is through radiator or do not pass through radiator.In case the temperature control valve block drag losses is excessive, the flow of system reduces corresponding, and the heat-sinking capability of cooling system also can descend; The water temperature that will cause getting into frequency converter is higher than set point; Frequency converter can't operate as normal, and the wind-powered electricity generation unit can't normally move, and causes the tremendous economic loss.
The primary structure of existing wind power generator unit frequency converter water cooling system temperature control valve block is such: the spool by bulb control is set in one section slideway of a rectangle valve body; One end of spool is kept out by valve body wall; The other end of spool is supported by spring, and spool can move around in slideway, has vertically offered frequency converter outlet passage, radiator backwater runner successively at an end of slideway; And vertical transverse passage-way; The outlet of transverse passage-way is the water pump suction inlet, and in order to be connected with water pump, said water pump suction inlet must be positioned at the central part of valve body.The flow path that special direction is arranged on the spool; When three diverse locations of spool at slideway; Through the flow path of special direction, can realize that vertical transverse passage-way connects with the frequency converter outlet passage respectively, or connects with radiator backwater runner, perhaps simultaneously and both parts connect.Because two runners and a passage all are vertical and slideway, are in the horizontal side of slideway medi-spring, flowing between coolant must be horizontally through spring; After the temperature-sensing valve bulb is met heat, expand, promote spool and move, in the moving process of spool; Spring stress compression, the circulation area of coolant reduce with the compression of spring gradually, because coolant must be gone into pump entrance through the radially straight channel outflow of the spool of temperature-sensing valve and spring is laggard in flowing; Therefore drag losses is bigger; After length of spring compressed arrived spacing value, it is maximum that resistance reaches, and flow system flow also drops to minimum; The cooling effect of system is influenced, causes operating mode, efficient, the life-span of whole air-cooled unit influenced.
Summary of the invention
The object of the invention; Plan provides a kind of structure-improved of wind power generator unit frequency converter water cooling system temperature control valve block; Make the circulation area of coolant not receive the compression of spring and change, no matter guarantee how spring compresses all can guarantee that spool is unobstructed, correct, accurate and move.
The objective of the invention is so to realize.
A kind of structure-improved of temperature control valve block of cooling system of wind generating set; Be included in the spool that is provided with in one section slideway of a rectangle valve body by bulb control; One end of spool is kept out by valve body wall, and the other end of spool is supported by spring, and spool can move around in slideway; Frequency converter outlet passage, radiator backwater runner have vertically been offered successively at an end of slideway; The central part that is positioned at valve body is offered the water pump suction inlet, it is characterized in that: the supporting surface at spring is axially offered shrinkage pool, by offering access ramp between shrinkage pool to the water pump suction inlet.
Further, the diameter of said shrinkage pool openend is less than spring diameter.
Further, on said spool, offer the flow path of special direction, make spool realize at three diverse locations of slideway:
Access ramp and frequency converter outlet passage are connected, and block with radiator backwater runner;
Access ramp and radiator backwater runner are connected, and block with the frequency converter outlet passage;
Access ramp is connected with frequency converter outlet passage and radiator backwater runner section simultaneously.
Adopt the present invention, generation is expanded or is shunk after the temperature-sensing valve bulb is met heat or cooling, promotes spool and moves around; Have three different positions; Produce three kinds of different working conditions, but which kind of situation no matter, the medium in frequency converter outlet passage and the radiator backwater runner; All can flow to the shrinkage pool of supporting base end portion through the spring axial inner, the access ramp of flowing through again flows out, flows into from the water pump suction inlet.Coolant has changed prior art must be perpendicular to the approach of spring lateral flow, and flows to the space of centre from spring shaft, can not receive length of spring compressed to increase the phenomenon of resistance again, has improved the control precision of temperature control valve block.
Advantage of the present invention and superiority: the passage of prior art wind power generator unit frequency converter water cooling system temperature control valve block is straight channel, and the temperature-sensing valve bulb is met the heat back and expanded, and promotes spool and moves; In the moving process of spool; Spring stress compression, the circulation area of coolant reduce with the compression of spring gradually, because coolant must be gone into pump entrance through the radially straight channel outflow of the spool of temperature-sensing valve and spring is laggard in flowing; Therefore drag losses is bigger; After length of spring compressed arrived spacing value, it is maximum that resistance reaches, and flow system flow also drops to minimum.So the resistance of whole temperature control valve block receives the influence of amount of spring compression very big.Adopt technical scheme of the present invention,, make the central part that is positioned at valve body offer the not change of position of water pump suction inlet the straight-through access ramp that changes into before the entering pump entrance; Still can directly be connected, not change the configured in one piece structure of frequency converter water cooling system, and the high-altitude is fixed, compact inner space, structure do not allow to change easily yet with the water pump suction inlet; Coolant is flowed through behind the spool; Through the axial outflow of spring, and through access ramp entering pump entrance, not only the resistance of system reduces greatly; And the situation of spring when moving also come into plain view, and fault is got rid of and the maintenance difficulty also reduces greatly.
The present invention only seems the change of a valve piece inner flow passage angle, the flow direction; But can meeting, this change satisfies the requirement that the water pump suction inlet must be positioned at the valve body central part; Transform input amount simultaneously and cost is again little, compared with prior art, brought complete various flows to the result; Produced the remarkable result that improves the temperature control valve block control precision, do not lost and have stronger creativeness.
