Problems solved by technology

This change may come from: 1) fouling of the heat exchanger, which reduces the heat exchange efficiency; 2) the wear of the water pump during long-term use reduces the cooling capacity; 3) deformation of the cooling fan blades reduces the cooling capacity; 4) The cooling motor wears out, resulting in reduced cooling capacity, etc.
This change is very likely to be gradual (and sometimes sudden), and the external manifestations are not obvious, so it is difficult to detect in time
In the production process where the cooling performance gradually decreases, there is a possibility of defective products
This kind of defective product may be difficult to find in the usual sampling inspection process, and it may take a long time to find out when the cooling characteristics have sufficiently deteriorated.
By this time, there may have been a considerable number of defective products, which may have constituted a major economic loss

Embodiment Construction

[0051] In this example, refer to image 3 As shown, the quenching cooling monitoring system includes a water cooling system 2, a heat exchange system 1 and a control system 3, and a clockwise arrangement of cold delivery pipes 4 and heat delivery pipes 5 arranged between the water cooling system 2 and the heat exchange system 1, And the cold end thermometer 41 arranged on the cold delivery pipe 4 for detecting the temperature of the coolant, and the flow meter 51, the hot end thermometer 52 and the water pump 53 arranged clockwise on the hot delivery pipe 5; The heat exchange system 1 is provided with an air-filled pressure gauge 14, a convection vane 12 and a heat exchanger 13. The convection vane 12 blows the heat on the workpiece 11 to the heat exchanger 13, and the cooling liquid transfers the heat to the heat exchanger 13. The heat is absorbed and taken away; the heat exchange system 1 is provided with a convection fan motor 54, the convection fan motor 54 is drivingly co...

Abstract

The invention discloses a quenching cooling monitoring system, comprising a water-cooling system, a heat exchange system, a control system, a cold delivery pipe, a heat delivery pipe, a cold end temperature measuring meter, a flow meter, a hot end temperature measuring meter and a water pump, wherein a plenum gauge is arranged inside the heat exchange system; the monitoring system calculates and records according to the real-time measurement information fed back by the cold end temperature measuring meter, the flow meter, the hot end temperature measuring meter and the plenum gauge. Thus, the online monitoring function of the cooling process is achieved; the monitoring data can be used as a foundation for quality judgment; the monitoring system also can emit a corresponding real-time control signal according to the actual cooling condition according to the preset and the actual cooling condition; the rotating speeds of a convection fan blade motor and a water-cooling system motor and gas pressure inside the heat exchange system are controlled to achieve the target of adjusting the cooling speed. The implementation of the quenching cooling monitoring system also can be used as equipment for detecting the cooling capacity of a vacuum furnace at regular intervals, and also can be used as an effective tool for a research design of the vacuum furnace. Thus, the energy-efficient target is achieved, and the trend of development of the technology at present is accorded.

Description

technical field [0001] The invention relates to a quenching and cooling monitoring system, in particular to a quenching and cooling monitoring system which is combined with a thermometer, a flow meter and an inflation pressure gauge to perform precise detection and control and accurately evaluate the effectiveness of the cooling system. Background technique [0002] For a gas quenching vacuum furnace, the main factor determining the cooling capacity (speed) is the heat transfer efficiency of the heat exchanger. The factors that affect the heat exchange efficiency are: cooling water flow rate, gas pressure in the cooling chamber (quenching chamber) and the speed of cooling fan blades. The cooling capacity of the gas quenching vacuum furnace determines its production capacity (applicable workpiece size, material type, etc.), and the stability of the cooling capacity determines the stability of the quality in batch production (large-scale repeated production of the same part) ...
