Abstract
The utility model relates to a preheating device for a circulation system in heat conduction oil furnace equipment. The preheating device for the standby circulation pump of the heat conduction oil furnace comprises circulation pumps. The inlet and the outlet of each circulation pump are respectively provided with a valve. The outlet of each circulation pump is provided with a unidirectional check valve. The pipeline of the inlet and the outlet of each unidirectional check valve is connected with preheating pipeline. A reverse flowing channel is formed for each unidirectional check valve so that the heat conduction oil flows through the standby circulation pump and performs a preheating function. The standby circulation pump is in a preheating state and can be smoothly activated at any time, thereby preventing compulsory activation at overload and cold/hot impact to the pump body, and reducing operation maintenance cost of the equipment.
Description
Technical field
The utility model relates to the preheating device of the circulatory system in a kind of heat-conducting oil furnace equipment.
Background technology
In the last few years, a kind of heat-conducting oil furnace equipment that can continuous heat supply was because its heat supply temperature was high; The equipment operating pressure is low, and advantage safe in utilization, its domestic application are more and more widely; Mainly be applied in industries such as oil, chemical industry, weaving respectively; In these occasions, general require must not be interrupted heat supply midway for continuous heat supply more.Important auxiliary device conduction oil circulating pump in the heat-conducting oil furnace is called as the heart of equipment, makes the heating agent carrier conduction oil in the system between body of heater and user's heat transmission equipment, form forced circulation, reaches heat exchange and the purpose that shifts heat energy; Otherwise equipment can't move, and stop transport for fear of the equipment that causes because of the circulating pump fault, and the equal polygamy of system is put a circulating pump as subsequent use; To tackle the appearance of circulating pump fault in service; Spare circulating pump is in halted state at ordinary times, when the operation circulating pump breaks down, starts spare circulating pump rapidly and puts into operation; The equipment that guaranteed continues operation; Operation circulating pump to fault keeps in repair then, can become the spare circulating pump identity after maintenance finishes, and gets into stand-by state.
The using and the reserved or many with the circulating pump system that is equipped with in; The import and export of each circulating pump are connected in parallel; Except that the circulating pump import and export are equipped with the conventional valve; Every circulating pump delivery side of pump also is equipped with one way stop peturn valve, does not produce conduction oil backflow short circuit when the stand-by state to guarantee spare circulating pump.In general heat-conducting oil furnace equipment, operating temperature is all than higher, and what have reaches 300 ℃; Under such operating mode; Operating circulating pump is operated in the condition of high temperature, and the circulating pump in subsequent use is in halted state, because the effect of circulating-pump outlet one way stop peturn valve; No thermal conductance flow of hot is environment temperature in the circulating pump pump housing in subsequent use.Most device context, circulating pump are outdoor open-air installation, and be very low at the winter temperature of northern area, even be low to moderate the chill point of conduction oil, and the spare circulating pump jiggering occurs and start difficulty.When in a single day operating circulating pump breaks down needs startup spare circulating pump; Because the spare circulating pump pump body temperature is lower; Cold conditions heat conduction oil viscosity is big in the pump housing, the problem of spare circulating pump can occur starting smoothly, and the process units of having incured loss through delay on-the-spot hot user normally moves; Overload by force repeatedly starts and can produce very big harm to the electrical appliance part of equipment; Even if once can start success, the spare circulating pump pump body temperature that is in cold conditions is elevated to operating temperature suddenly in moment, and violent thermal shock also produces bigger harm for the pump housing.Such operation meeting direct service life that influences equipment influences on-the-spot ordinary production, and the equipment fault probability of happening raises, and causes the equipment operation maintenance cost to increase.The utility model is through on every circulating pump, increasing a simple and easy piping installation, makes the circulating pump in subsequent use be in preheat mode, can start success smoothly at any time, has thoroughly avoided above-mentioned problem.
Summary of the invention
The purpose of the utility model is to avoid the deficiency of prior art that a kind of heat-conducting oil furnace spare circulating pump preheating device is provided; Can make spare circulating pump require to be in through this device by preheat mode according to operation; Accomplish to start operation smoothly at any time; Shorten equipment idle time, reduced the probability of device fails.
For realizing above-mentioned purpose; The technical scheme that the utility model is taked is: a kind of heat-conducting oil furnace spare circulating pump preheating device; Comprise that inlet of circulating pump and outlet are equipped with valve, one way stop peturn valve also be installed on the circulating-pump outlet, on the pipeline that one way stop peturn valve is imported and exported parallel connection the preheating pipeline; One way stop peturn valve is formed a reverse flow passage, make the circulating pump that conduction oil flows through in subsequent use produce the preheating effect; Aciculiform control valve, snakelike separator tube are installed on the described preheating pipeline, safeguard and use slip-knot.
Further, described aciculiform control valve is not limited to aciculiform control valve form, as long as can control preheating and promptly be applicable to the utility model with the valve of conduction oil flow through regulating its aperture size.
Further, described snakelike separator tube be have serpentine shaped can the cold and hot expansion of suction line and the seamless steel pipe of installation dimension error.
Further, described maintenance has been stopped leakage with slip-knot and the welding of preheating pipeline.Be with whole pipeline of preheating and the parts that the circulating pump pipeline separates, make things convenient for packaging products in boxes to dispatch from the factory to transport and the maintenance maintenance of operational phase.
The beneficial effect of the utility model is: in the circulating-pump outlet pipeline, used the preheating piping installation, through opening aciculiform control valve in the preheating pipeline, be under the operating circulating pump effect; With reference to shown in Figure 2, a part of high temperature heat conductive oil can flow into the pump housing from the circulating-pump outlet that is in subsequent use through the preheating pipeline, flows out from the import of the pump housing; To being in the preheating that heats up of circulating pump in subsequent use,, can control the flow of preheating with conduction oil through regulating the aperture of aciculiform control valve; Circulating pump preheat temperature in subsequent use is controlled; Make the circulating pump pump body temperature in subsequent use be controlled in the temperature range that can start smoothly, when being in operating circulating pump and breaking down, accomplish immediately, once to start smoothly the circulating pump in subsequent use; Shortened greatly in the routine techniques because of repeatedly starting the idle time that spare circulating pump causes; Reduce user's stopping production loss, alleviated the device operator workload, avoided the force start under the overload load; Reduced thermal shock, reduced fault probability of happening and equipment operation maintenance expense the pump housing.When summer temp is high, if need not carry out preheating, can close the aciculiform control valve, stop the circulating pump in subsequent use is carried out preheating.
