Description
1, technical field
The present invention relates to a kind of heat transmission equipment, specifically a kind of intelligent type frequency-conversion and energy-saving heat-exchange equipment that pressurizes with heating agent indirect heat exchange, circulation.
2, background technology
Continuous development along with city-building, the central heating in cities and towns or zone has become the main force of social heat supply, but the centralized heat transmission equipment of prior art often just links up heat exchanger, water circulating pump, small pump, dirt separator etc. with pipeline, take up an area of big, and there is not electric-control system, need professional operations staff's real-time monitoring, water pump operation noise height during the equipment operation; Also there are indivedual heat transmission equipments to dispose electric-control system, but because the control system unreasonable allocation can not reach the intelligent energy-saving run of heat transmission equipment; In addition, in heat transmission equipment, water circulating pump, small pump start frequent, have influenced the service life of equipment significantly.
3, summary of the invention
Deficiency in view of above-mentioned prior art exists the invention provides a kind of intelligent type frequency-conversion and energy-saving heat-exchange equipment.
The technical solution adopted for the present invention to solve the technical problems is: intelligent type frequency-conversion and energy-saving heat-exchange equipment is by heat exchanger, water circulating pump, small pump, expansion tank, the electric hydaulic temperature-sensing valve, dirt separator and switch board are formed, the primary side inlet tube connects with heat exchanger through the electric hydaulic temperature-sensing valve, water circulating pump is located on the heat exchanger secondary side inlet tube, and on the secondary side inlet tube, be provided with safety valve, the safety valve outlet connects expansion tank, water circulating pump links to each other with return pipe, and be provided with the water circulating pump bypass pipe, filling pipe connects expansion tank, be provided with fluid level controller in the expansion tank, the expansion tank outlet takes back water pipe through small pump, and magnetic valve is equipped with in the small pump parallel connection, be provided with the heat exchanger bypass pipe at secondary side in addition, before return pipe and the electric hydaulic temperature-sensing valve dirt separator is housed, the primary side inlet tube, the primary side outlet, be respectively equipped with temperature transmitter and pressure sensor on secondary side inlet tube and the secondary side outlet, also be provided with pressure sensor on the return pipe, and be provided with outdoor temperature sensor, water circulating pump, small pump, fluid level controller, magnetic valve, the electric hydaulic temperature-sensing valve, temperature transmitter, pressure sensor and outdoor temperature sensor be the wiring switch board respectively, is equiped with SM510 intelligent controller and touch-screen on the switch board.
Water circulating pump and small pump adopt VFC by switch board, small pump is realized the constant pressure of return pipe, and realize automatic start-stop by return pipe setup pressure value and running frequency, when return pipe pressure reaches the pressure sensor setting pressure, small pump enters the termination of pumping resting state, save power consumption, when return pipe pressure was lower than the pressure sensor setting pressure, small pump started automatically; When if system causes that because of variations in temperature return pipe pressure exceeds setup pressure value 0.03~0.05MPa, switch board control magnetic valve is opened pressure release automatically, treat that magnetic valve is opened to that return pipe pressure is lower than the 0.02MPa of setup pressure value and when following, magnetic valve cuts out automatically.Like this, by system's automatic water supplement, releasing pressure automatically, reach the safe operating mode of secondary side pressure constant voltage.
Water circulating pump is then controlled by system's pre-set program realization frequency conversion automatically according to outdoor temperature sensor, secondary side inlet tube and secondary side outlet temperature difference or water circulating pump inlet and outlet pressure difference, reaches the purpose of water circulating pump energy-saving run.When the water circulating pump outlet pressure was higher than safety valve setting pressure, safety valve was opened pressure release automatically, avoided taking place for the security incident that maloperation causes because of the people.
The electric hydaulic temperature-sensing valve is regulated the amount that realizes secondary side according to the secondary side outlet temperature of band outdoor climate compensation by PID and regulated, and reaches temperature-compensating, greatest priority conversion round the clock, and is further energy-conservation.
The SM510 intelligent controller adopts modularized design, and clamping-rail is installed, and has fast accurate PID and regulates, and can realize teletransmission setting or monitoring by connecting host computer and GPRS.Touch-screen can be observed equipment running status intuitively, and can store by the SM510 intelligent controller, accomplishes unattended fully automatic operation.
Profitable fruit of the present invention is that water circulating pump and small pump adopt VFC, and are combined with electric hydaulic temperature-sensing valve and outdoor temperature sensor realization adjustment, advanced technology, control system optimization can realize various intelligent energy conservation models, unmanned takes up an area of for a short time, and noise is low, cost performance height, and system's automatic water supplement, releasing pressure automatically, intelligent liquid crystal display, can make things convenient for on-site supervision, easy to operate, the automaticity height.
