Description
Technical field
The utility model relates to a kind of water replanishing device, specifically a kind of heating unit energy conservation water replanishing device belongs to benefit
Water installations field.
Background technique
In current all water water heat-exchange units, most of is using traditional water supplementing method, i.e., first by originally water flow
To water supply tank, then the water in water supply tank is supplemented to heating system by small pump.This structure is primarily present following drawback:
(1) energy waste, since water tank is open system, the original potential energy of tap water becomes zero after flowing to water tank, so
The water in water tank is subjected to pressure-raising by small pump afterwards, the original pressure head of tap water (potential energy) is unutilized, causes energy waste.
(2) accelerate heating system pipe network oxidation (corrosion).Tap water flows to the water stored in the process and water tank of water tank, by
In air, increase the oxygen content in original tap water in all exposures, then mended by small pump to after heating system, due to water
Oxygen content increases, to accelerate the oxidation of heating system, shortens the pipe network service life.
Summary of the invention
To solve the above-mentioned problems, the utility model devises a kind of heating unit energy conservation water replanishing device, takes full advantage of
The original pressure head potential energy of tap water, saves electric energy, extends the heating system pipe network service life, reduces costs.
The technical solution of the utility model are as follows:
Heating unit energy conservation water replanishing device, including water pump, the water inlet of the water pump are connected with tap water, tap water into
Enter water pump, there is certain pressure, is airtight connection, the water outlet of the inlet of the tap water and the water pump with water pump water inlet
It is mounted on pressure transmitter at mouthful, the pressure signal of the pressure transmitter is respectively connected to the PLC controller of control cabinet, described
PLC controller judges whether tap water has water, the PLC controller and water pump control according to the pick-up value of running water pressure power transmitter
System is connected, and controls the start and stop and pump rotary speed size of water pump, is pressed according to pump outlet pressure transmitter and PLC controller setting
Power decides whether start and stop water pump and pump rotary speed size.
The control cabinet is additionally provided with breaker and relay.
The water inlet of the water pump is connected by the first gate valve with the first rubber soft-jointing.
The water outlet of the water pump is connected by check-valves with the second gate valve, between the check-valves and second gate valve
Equipped with the second rubber soft-jointing.
Utility model has the advantages that the original pressure head potential energy of tap water is taken full advantage of, due to tap water and heating
System (supplying water after small pump pressurization for heating system, sent after heat exchanger heats to each user) is closed system, is made original
The power of small pump substantially reduces, and saves electric energy；Without the chance that water is contacted with atmosphere, the oxygen content of water is reduced, is prolonged
The heating system pipe network service life is grown；Investment is saved, water supply tank is eliminated, keeps heating equipment occupied area smaller, cost is lower.
The utility model is described in further detail with reference to the accompanying drawings and examples.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model embodiment.
Specific embodiment
The preferred embodiment of the utility model is illustrated below, it should be understood that preferred embodiment described herein
It is only used for describing and explaining the present invention, is not used to limit the utility model.
Embodiment 1
As shown in Figure 1, a kind of heating unit energy conservation water replanishing device, including water pump, the water inlet and tap water of the water pump
It is connected, tap water enters water pump, has certain pressure, is airtight connection, the inlet of the tap water with water pump water inlet
It is mounted on pressure transmitter 3 with the water outlet of the water pump 2, the pressure signal of the pressure transmitter 3 is respectively connected to control
The PLC controller of cabinet 1 processed, the PLC controller judge whether tap water has water according to the pick-up value of running water pressure power transmitter,
The PLC controller is connected with water pump control, controls the start and stop and pump rotary speed size of water pump, is become according to pump outlet pressure
It send device and PLC controller to set pressure and decides whether start and stop water pump and pump rotary speed size.
The control cabinet is additionally provided with breaker and electrothermal relay, and breaker is the power switch of control cabinet, determines power supply
On-off.Electrothermal relay is electic protection element, makes contact closure or disconnection using the fuel factor pushing action mechanism of electric current.
The water inlet of the water pump is connected by the first gate valve 41 with the first rubber soft-jointing 51, and water flow can be cut off in gate valve, side
Just the replacement and maintenance of water pump, soft connect play damping in the unit, have increased the service life of water pump and pipeline.
The water outlet of the water pump 2 is connected by check-valves 6 with the second gate valve 42, after water is pressurizeed by water pump, water
Pressure becomes larger, and check-valves can prevent the reflux of water in pipeline, protects the safety of water pump, increases the service life of water pump, described to stop
It returns and is equipped with the second rubber soft-jointing 52 between valve 6 and second gate valve 42, reduce vibration, increase the pipe fitting service life.
