Traditional generating set adopts the mode installing cooling fan to accelerate air circulation, thus realizing air-cooled. Along with the development of motor technology, especially for the use occasion that some are special, the simple air-cooled cooling that obviously cannot meet generating set require that, the index such as noise, functional reliability is required for being further enhanced.
Summary of the invention
The technical problem to be solved is, for the shortcoming that above prior art exists, it is proposed to a kind of electromotor circulation water cooling device, not only can improve the efficiency of internal combustion engine, but also can reduce surrounding enviroment thermal pollution.
This invention address that the technical scheme of above technical problem is: provide a kind of electromotor circulation water cooling device, including being arranged in electromotor at least two group heat exchanger plates, the water inlet of described heat exchanger plates is adjusted valve, stop valve, filter and water-delivery pump successively and is connected with cyclic water tank outlet; The water inlet that the outlet of described heat exchanger plates accesses described cyclic water tank through turbine flowmeter, stop valve and Heat Exchanger in Circulating Water System successively is connected, and the import and export of the cooling journey of described Heat Exchanger in Circulating Water System cool down water intake-outlet with outer circulation and are connected; Described filter outlet is provided with the first arm installing flow control valve, and the outlet of described first arm is connected with described cyclic water tank water inlet through activated-charcoal column.
The technical scheme that the present invention limits further is: aforesaid electromotor circulation water cooling device, switching bypass it is provided with between two stop valves between the water inlet of two adjacent groups heat exchanger plates, described switching bypass is provided with stop valve, and is connected with the water inlet of described Heat Exchanger in Circulating Water System.
Aforesaid electromotor circulation water cooling device, described water-delivery pump is composed in parallel by two centrifugal pumps, and the import and export of every centrifugal pump are mounted on stop valve.
Aforesaid electromotor circulation water cooling device, the import and export of described filter is mounted on Pressure gauge.
Aforesaid electromotor circulation water cooling device, described cyclic water tank is closed structure, and is provided with draining main valve bottom described cyclic water tank.
Further, aforesaid electromotor circulation water cooling device, described heat exchanger plates is composed in parallel by least two boards formula heat exchanger fin.
Because the cooling system of the present invention needs long-term, continuous operation, so consider the maintenance problem of consumable accessory when designing pipeline. Valve all it is provided with, it can be switched over when breaking down, to change device in the front and back end of two pumps and turbine flowmeter. Pipeline is also provided with switching and bypath valve, for controlling the flow direction of coolant. It is simultaneously provided with modeled pressure drop system, flow during for stably switching. For the flow on each road, system is equipped with corresponding choke valve and is adjusted. In order to ensure the quality of coolant, system is also equipped with filtration, purification facility.
The invention has the beneficial effects as follows:
The circulating water cooling system of the present invention is reasonable in design, compact conformation. Have employed novel centrifugal pump in the design, noise is low, stable performance; Heat exchanger volume is little, efficiency is high; Flow switch is stable; System maintenance is convenient. Owing to adopting activated-charcoal column, effectively eliminate the incrustation scale that internal recycle water produces in heating process, it is ensured that the heat-conducting effect of heat exchanger plates can keep best working condition, reduced the fault rate of blood circulation, reliably meet designing requirement.
