Abstract
The utility model relates to a plate heat exchanger unit capable of automatically detecting the resistance of a plate heat exchanger. The plate heat exchange unit comprises a plate heat exchanger, and is characterized by also comprising a control alarm box, and the primary side inlet and outlet of the plate heat exchanger and the secondary side inlet and outlet of the plate heat exchanger are respectively provided with a pressure transmitter; and the signal output ends of the four pressure transmitters are respectively and electrically connected with the signal input end of the control alarm box. According to the plate heat exchanger unit provided by the utility model, the troubleshooting difficulty during overhauling is greatly reduced, thereby saving a lot of manpower and resources, shortening the maintenance time, and reducing the daily operating cost.
Description
Technical field
The utility model relates to the concentrated supply of heating in the city field, especially a kind of plate-type heat-exchange unit that can detect the heat-exchangers of the plate type resistance automatically.
Background technology
At present, the plate-type heat-exchange unit is mainly used in the concentrated supply of heating in the city field, the plate-type heat-exchange unit is made up of heat-exchangers of the plate type, water pump, instrument, electrical equipment, control system and necessary auxiliary device etc., realizes that exchange heat is the heat-exchanger rig of purpose between fluid.Appearance along with it simultaneously makes the heat exchange base station more energy-conservation, more intelligent.Along with deepening continuously of national energy-saving and emission-reduction thought, central heating is popularized in China most of heating area, even also begins to carry out central heating in some high-grade residential quarters, south.Central heating just makes many arcolas room make heat exchange station into thereupon, simultaneously newly-built residential quarter and mansion also on ground or underground investment construction modern heat exchange station.How heat exchange station adopts the plate-type heat-exchange unit as the basic equipment in the station again as the basic cell of central heating, though the once net temperature of heat exchanger often takes place than higher in the heat-exchangers of the plate type of this basic equipment in running, but the temperature increase of the secondary net of heat exchanger is also not obvious, often the place that can not pinpoint the problems timely again.Thereby cause the blindness of heat exchange station maintenance, unnecessary manpower and materials and maintenance time have been wasted greatly, influence the carrying out of heating work, in addition, because present most plate-type heat-exchange unit all adopts the dismountable plate type heat exchanger as main heat exchange element, because separating out of the calcium ions and magnesium ions in the impurity of medium and the anvil cinder that the heat-exchange system pipeline rust causes and the heat transferring medium, cause the runner of plate type heat exchanger to stop up and make the heat exchange efficiency decline of heat exchanger, thereby though the not hot situation of secondary net of the awfully hot heat exchanger of once net of heat exchanger is taken place.Because the obstruction of heat-exchangers of the plate type is again a hidden failure that is difficult for judgement, is easy to be ignored by people, and the maintenance of heat exchange station and maintenance difficulties are strengthened greatly.
The utility model content
For overcoming the problem that occurs in the above-mentioned application, this is practical to provide a kind of plate-type heat-exchange unit that can detect the heat-exchangers of the plate type resistance automatically.
The technical scheme that adopts is:
Can detect the plate-type heat-exchange unit of heat-exchangers of the plate type resistance automatically, comprise heat-exchangers of the plate type, it is characterized in that it also comprises a control warning box, a pressure transmitter is respectively installed in the primary side import of described heat-exchangers of the plate type and outlet and secondary side import and outlet, and the signal output part of four pressure transmitters is electrically connected with the signal input part of control warning box respectively.
Operation principle
A control of outer installation warning box.Heat exchanger is when normal operation, and to fall be very little to the pressure of thermal medium and cold medium in the heat-exchangers of the plate type, (generally should less than 0.3bar).Because separating out of the anvil cinder that the impurity in the medium and heat-exchange system pipeline rust cause and the calcium ions and magnesium ions in the heat transferring medium caused the runner of heat-exchangers of the plate type to stop up, and made heat-exchangers of the plate type once, increasing falls in the pressure of secondary side.The utility model is the primary side import with heat-exchangers of the plate type, outlet and secondary side import, the pressure signal of four pressure transmitters of outlet is sent to the control warning box through the computing of pressure controller unit, as long as the secondary side inlet and outlet pressure difference of the inlet and outlet pressure difference of the primary side of heat-exchangers of the plate type or heat exchanger during greater than setting value, is sent to alarm unit with alarm signal again and sends alarm signal.Just illustrate that heat-exchangers of the plate type stops up.
Remind user workman in time to clean plate type heat exchanger.Make the maintenance of heat exchange station have specific aim, the investigation difficulty of fault when greatly reducing maintenance.Thereby saving lot of manpower and material resources and repair time, is that everything goes well with your work carries out in heating.
The investigation difficulty of fault when the utility model greatly reduces maintenance, thus save lot of manpower and material resources and repair time, reduce the day-to-day operation expense.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Can detect the plate-type heat-exchange unit of heat-exchangers of the plate type resistance automatically, comprise heat-exchangers of the plate type 3, its characteristics are that it also comprises a control warning box 7, primary side import and the outlet of heat-exchangers of the plate type are separately installed with pressure transmitter 1,2, and secondary side import and the outlet of heat-exchangers of the plate type are separately installed with pressure transmitter 3,4.A butterfly valve is respectively installed in the primary side import of heat-exchangers of the plate type and outlet and secondary side import and outlet, and four pressure transmitters 1,2,3,4 signal output part are electrically connected with report to the police 7 casees signal input part of control respectively.Control warning box 7 is known product.
Computing through the pressure controller unit, as long as the secondary side inlet and outlet pressure difference of the inlet and outlet pressure difference of the primary side of heat-exchangers of the plate type 3 or heat exchanger is during greater than setting value, again alarm signal is sent to control warning box 7, sends alarm signal, just illustrate that heat-exchangers of the plate type stops up.
