Abstract
The utility model discloses an energy-saving control system, this energy-saving control system are applied to in air conditioner or water supply network system do not have open-ended closed water circulating system, including first water pump and the first start control ware of being connected with first water pump, its characterized in that still includes the second water pump with first water pump parallel connection, and second start control ware is connected to this second water pump, be equipped with first converter, second converter between first water pump and the first start control ware, between second water pump and the second start control ware respectively. The utility model can save energy to the utmost extent; when the double machines are operated in parallel, the water pump overcomes the mechanical abrasion in a high-speed fatigue operation state for a long time, so that the maintenance rate of the water pump is greatly reduced, and the maintenance cost, the labor cost and the economic cost of shutdown maintenance are reduced.
Description
Technical field
The utility model relates to energy-saving control system, more particularly, relates to and a kind ofly is applied to air-conditioning or water supply pipe net system does not have in the closed circulating water system of opening, comprise water pump and with the energy-saving control system that starts controller.
Background technique
At present, the energy-saving control system of existing application in air-conditioning or water system is to adopt a water pump 2 ' and a startup controller 4 ', and a standby water pump 1 ' and (the using and the reserved) control system that starts controller 5 ', as shown in Figure 1.
The defective that this mode exists: be in the mechanical wear under the tired running state of high speed for a long time, the maintenance rate of water pump is increased greatly, increased the financial cost of maintenance cost and cost of labor and shutdown maintenance, the most important thing is to have increased waste of electric energy.
Summary of the invention
At above-mentioned technological deficiency, the utility model provides a kind of energy-saving control system, and this a kind of energy-saving control system adopts two-shipper parallel control system, be prior art when power frequency operation power 1/4, energy-saving effect is more remarkable.
The technological scheme that its technical problem that solves the utility model adopts is as described below: a kind of energy-saving control system, this energy-saving control system is applied to air-conditioning or water supply pipe net system does not have in the closed circulating water system of opening, comprise first water pump and the first startup controller that is connected with first water pump, it is characterized in that, also comprise second water pump that is connected in parallel with first water pump, this second water pump connects second and starts controller, and described first water pump and first starts between the controller, be respectively equipped with first frequency variator between second water pump and the second startup controller, second frequency variator.
According to the utility model of said structure, its beneficial effect is, 1, in closed pipe network, there is not actual lift, and at this moment the total head of pump is the loss lift sum that other resistances cause in pipeline, joint, valve and the pipeline; The pressure release of pipeline is satisfied by the supercharging of small-power small pump, and the lift of enclosed pipeline and the speed governing of main pump influence are ignored, and in this environment, the utility model can be energy-conservation to greatest extent; 2, when the two-shipper parallel running, its water pump has overcome the mechanical wear that is in for a long time under the tired running state of high speed, and the maintenance rate of water pump is reduced greatly, has reduced the financial cost of maintenance cost and cost of labor and shutdown maintenance.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
Fig. 1 is the prior art structural representation;
Fig. 2 is the utility model structural representation.
Embodiment
As shown in Figure 2, a kind of energy-saving control system, comprise first water pump 2 and the first startup controller 4 that is connected with first water pump 2, also comprise second water pump 1 that is connected with first water pump 2, this second water pump 1 connects second and starts controller 5, this second starts controller 5 and first and starts controller 4 and is connected, between described first water pump 2 and the first startup controller 4, be respectively equipped with first frequency variator 3, second frequency variator 6 between second water pump 1 and the second startup controller 5.
Under the prerequisite that does not change flow, pressure (lift) can not consider that (in closed pipe network, then do not have actual lift, at this moment the total head of pump is the loss lift sum that other resistances cause in pipeline, joint, valve and the pipeline; The pressure release of pipeline is satisfied by the supercharging of small-power small pump, and the lift of enclosed pipeline influences with the speed governing of main pump ignores), according to pump operating characteristic: the power of two pump operations be a pump when power frequency operation power 1/4.
The roadability of water pump is as follows:
1) flow of water pump is directly proportional with the first power of rotating speed: Q=N;
2) temperature difference △ T and rotating speed first power are inversely proportional to, △ T=l/n;
3) lift H is directly proportional H=N with the rotating speed quadratic power
2
4) air horsepower P is directly proportional P=N with the cube of rotating speed
3
Though the utility model is described with reference to the above embodiments; it only is for explanation the utility model that but those of ordinary skill in the art can very clearly be recognized above embodiment fully; wherein can make variations and modifications and not break away from the utility model in a broad sense; so be not that conduct is to restriction of the present utility model; as long as in connotation scope of the present utility model, all will fall within the protection domain that the utility model requires above-described embodiment's variation, distortion.
