Description
Technical Field
The utility model relates to a refrigeration air conditioner technical field, especially can timing control's water conservancy modular structure.
Background
The traditional air conditioning system consists of a host device, a terminal device and a waterway system. The waterway system comprises a water pump, a valve, a pipe fitting, an instrument, a pipeline, a control device, a water replenishing device, a pressure difference bypass and the like, and the problems of more equipment pipelines, more installation nodes and the like exist in field installation. The advent of hydro modules has made system installation simple.
In the prior art, a water pump in a hydraulic module unit generally adopts a one-use one-standby design, and two sets of water pumps alternately run and are mutually standby. The manual operation switches two sets of water pump operation, can lead to two sets of water pump operation time length discordance, and water pump life is influenced, can not play reserve effect.
Disclosure of Invention
To the deficiencies existing in the prior art, the utility model aims to provide a hydraulic module structure capable of timing control. The automatic switching device can be switched between a manual mode and an automatic mode at will, the running time of the two water pumps can be automatically switched in the automatic mode, the normal running of a system is ensured, and the service life of the water pumps is prolonged.
In order to achieve the above object, the technical solution of the present invention is implemented as follows:
a hydraulic module structure capable of timing control comprises a closed circuit breaker, two water pump motors, two stop buttons and two start buttons, wherein the two stop buttons and the two start buttons are used for respectively controlling the two water pump motors, a first protection switch and a first alternating current contactor are arranged on one branch of each water pump motor, and a second protection switch and a second alternating current contactor are arranged on the second branch of each water pump motor. It is characterized by that it also includes a manual/automatic change-over switch and a double-circulation relay capable of respectively controlling two starting buttons.
The utility model discloses owing to adopted above-mentioned structure, when the system is in manual state: the switch of the two water pumps is completely operated by an operator by a control box panel start-stop button. When the system is in the automatic state: the two water pumps are controlled by a double-circulation relay and are switched to automatically start and stop in turn.
Compared with the prior art, the utility model discloses following beneficial effect has:
(1) and the running time of two water pump loops in the hydraulic module is ensured to be consistent.
(2) The service life of the water pump is prolonged.
(3) The control and maintenance are convenient, and the manual operation cost is reduced.
The present invention will be further described with reference to the accompanying drawings and the following detailed description.
Drawings
Fig. 1 is a schematic circuit diagram of the present invention.
Detailed Description
Referring to fig. 1, the utility model discloses hydraulic module structure that can time-recorder control includes closed circuit breaker 1, manual/automatic transfer switch, two water pump motors and controls two stop button, two start button of two water pump motors respectively and can control two start button's two circulation relay 12 respectively. A first protection switch 2 and a first alternating current contactor 5 are arranged on a first 6 branch of the water pump motor, and a second protection switch 3 and a second alternating current contactor 8 are arranged on a second 9 branch of the water pump motor.
The utility model discloses when needs manual intervention system operation or maintenance debugging, arrange manual state in with manual/automatic change over switch, press a start button 4 after, ac contactor one 5 has got the electricity, and the main contact is closed, and water pump motor is the operation of 6 beginning. And after the second starting button 7 is pressed, the second alternating current contactor 8 is electrified, the main contact is closed, and the second water pump motor 9 starts to operate. After a first stop button 10 is pressed, a first coil 5 of the alternating current contactor is powered off, a main contact is disconnected, a first water pump motor 6 stops running, and after a second stop button 11 is pressed, a second coil 8 of the alternating current contactor is powered off, the main contact is disconnected, and a second water pump motor 9 stops running.
The utility model discloses when needs automatic operation, arrange hand/automatic transfer switch in automatic state, double-circulation relay 12 gets electric this moment, gets into the time t1 and t2 that the menu set up two water pump circulation operations in turn. After the setting is finished, when the operation needs to be started, the system gives an automatic operation signal, and the system alternately switches the closing positions of the double-circulation relays 12 according to preset time t1 and time t2, so that the automatic circulation alternate operation of the two water pumps is realized.
The utility model discloses when placing manual state in: the switch of the two water pumps is completely operated by an operator by a control box panel start-stop button. This scheme is applicable to when a water pump return circuit broke down, and operating personnel can switch to another set of water pump operation. When placed in the automatic state: the two water pumps are controlled by a double-circulation relay 12 and are switched to be automatically started and stopped in turn. When the system gives an operation signal, the first water pump motor 6 starts to operate, the first water pump motor 6 stops after the time period of t1, the second water pump motor 9 starts to operate, and the first water pump motor 6 is switched after the time period of t2, so that the operation is repeatedly cycled until the system gives a stop signal. the time t1 and the time t2 are set within the range of 0.02S-500 h. The scheme is suitable for the water pump to be used alternatively in a normal operation state, and continuous and stable operation of the double-loop system is guaranteed.
The above-mentioned embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the present invention. It will be apparent to those skilled in the art that various changes and modifications can be made in the invention without departing from the spirit and scope of the invention.
