Technical field:
The utility model relates to a kind of heat exchanger heat exchange unit, especially designs a kind of full-automatic easily maintenance from protection heat exchange unit.Be mainly used in the relevant industries of needs use heat exchanger units such as heating, air-conditioning, refrigeration, petrochemical industry, chemical industry, industry, food, electric power, metallurgy.
Background technology:
Present heat exchange unit majority can not be realized truly full-automatic, and these units need work such as the special regular manual blowdown of personnel, exhaust in operation.The maintenance more complicated, and need to be equipped with the professional, cost is higher.And present heat exchange unit is subjected to the restriction of automaticity, and maintenance is a complicated job, needs a plurality of people to carry out data acquisition respectively, loses work such as ruuning situation detection.And the heat exchange unit scarcely adds the exterior protection housing; and adopt open arrangement; do so promptly and can not protect the various parts that are installed on the unit, it is more mixed and disorderly that the heat exchange station of installing behind the heat exchange unit is arranged, increases the design difficulty of heat exchange station.Even if added the heat exchange unit of external shell, its housing also only can play a protective role to unit, can not be to the regular maintenance of unit and the operation condition that facilitates.
Summary of the invention:
The utility model is in order to solve the blowdown manually regularly that present heat exchange unit exists, exhaust is untimely, the maintenance inconvenience, it is higher to be equipped with professional's cost, the heat exchange unit does not add the exterior protection housing, be unfavorable for protection to the various parts on the unit, can not be even if added external shell to the facilitate technical problem of condition of the regular maintenance of unit and operation, provide a kind of full-automatic easily maintenance from protection heat exchange unit, it comprises pedestal and places the unit on the pedestal to protect structure outward, described unit protects the interior heat exchange unit of structure mainly by heat exchanger outward, circulating pump, small pump, electric control valve, flowmeter, valve, sensor, pipeline and conduit coupling are formed, and both sides respectively are provided with two slide rails that are parallel to each other on described pedestal; Described machine unit shell is made of integrated switch board, slide and external interface cabinet three parts; Described integrated switch board is positioned at the end that unit is protected structure outward, which is provided with the integrated instrument operation bench of switch board, and end face is provided with the switch board access door; Described external interface cabinet is positioned at the other end of outer protection structure, and externally interface cabinet top is provided with the unit installing port, and the bottom is provided with sewage draining exit, and end face is provided with the heat dissipation ventilation mouth; Described slide is made up of two fan arch dodge gates, and bottom, dodge gate two sides places respectively on the pedestal in separately the slide rail; On the heat exchange unit pipeline outside described in the protection structure automatic dirt separator is housed also.
Characteristics of the present utility model and beneficial effect: compact conformation, volume are little; Shell is elegant in appearance, and is practical; Housing is provided with that slide is easy to maintenance, safety good; Automatic pollution discharge, saving manpower, effect is good, has prolonged the service life of unit; Being fit to very much the building residence installs and uses.Truly realized the unit full-automation, realized that simultaneously the heat exchanging unit protects functions such as installation, maintenance easily.

The specific embodiment:
Referring to Fig. 1-Fig. 6, full-automatic easily maintenance is from protection heat exchange unit, it comprises pedestal 1 and the machine unit shell that places on the pedestal 1, and the heat exchange unit in the described machine unit shell is mainly by heat exchanger 13, circulating pump 14, small pump 15, electric control valve 17, flowmeter 18, valve 19, sensor 20, pipeline 21 and conduit coupling are formed, and both sides respectively are provided with two slide rails that are parallel to each other 11 on described pedestal 1; Described machine unit shell is made of integrated switch board 2, slide 3 and external interface cabinet 4 three parts; Described integrated switch board 2 is positioned at an end of machine unit shell, which is provided with the integrated instrument operation bench 5 of switch board, and end face is provided with switch board access door 6; Described external interface cabinet 4 is positioned at the other end of machine unit shell, and externally interface cabinet 4 tops are provided with unit installing port 8, and the bottom is provided with sewage draining exit 9, and end face is provided with heat dissipation ventilation mouth 12; Described slide 3 is made up of two fan arch dodge gates, and bottom, dodge gate two sides places respectively on the pedestal 1 in separately the slide rail 11; On the heat exchange unit pipeline in described machine unit shell automatic dirt separator 16 is housed also.On described integrated switch board 2 and the external interface cabinet 4, be provided with the spacing lock 7 of slide near slide 3 one sides.Be provided with unit exhaust outlet 10 in the side of described pedestal 1.
The control system of integrated switch board inside is mainly by controller, the integrated instrument operation bench of switch board, and touch-screen, frequency converter constitutes.Have parameter and state to show on the touch-screen, temperature and pressure real-time curve show, the hand of water pump and valve, control automatically, time-program(me) function etc.Show the pressure and the temperature data of current unit operation, the state of water pump and valve, the overload alarm information of temperature, pressure, the real-time curve of temperature and pressure by touch-screen and instrument operation bench.The data on flows that has also shown unit simultaneously.
The heat exchange unit mainly partly is made of heat exchanger, water pump, full-automatic control system, sensor and instrument, valve, automatic decontamination apparatus, pipeline, outer protection structure etc.
The outer protection structure mainly by pedestal, ensure that the machine unit shell that the framework of set structure intensity constitutes, slide and slide rail, heat dissipation ventilation system and integrated instrument operation bench and integrated switch board, the external interface cabinet etc. of being convenient to the unit maintenance maintenance form.The heat dissipation ventilation system mainly is made up of air filtration grid and fan etc.Purpose is by rational design air channel layout, gives the enough heat-dissipating spaces of each electric elements, and main heat generating components is isolated, and the heat that produces when simultaneously electric elements being moved is in time got rid of, for electric elements are built an optimum operation environment.Integrated instrument operation bench and integrated switch board are concentrated instrument and man-machine communication interface external, are convenient to observe and operation, only need operating personnel, can finish every work such as the parameter setting of system and data acquisition easily.
During installation, after the unit that assembles is transported to heat exchange station, pipeline corresponding in each external trunk line interface of unit, sewage draining exit, exhaust outlet etc. and the heat exchange station is connected, power supply is introduced in the unit switch board, after water filling powers on, can carry out the commissioning test work of unit.Because this product unique design structure makes that the pipe-line layout optimization in the station is reasonable, every installation is very easy.
During regular maintenance,, in unit running process, need not the people and implement peripheral operation, the controller automatic dirt separator of control blowdown voluntarily regularly by automatic dirt separator.
When having parts to overhaul or to change on the unit, parts can be overhauled, changed to the slide unlatching.Only need people's independent operation, simple and fast.
