Abstract
The invention provides a power saving device for a water pump of an oil pipeline. The device is intelligently controlled by a microcomputer, and is provided with a built-in special PID (proportion integration differentiation) regulator. If pressure is still lower than a set value when the running frequency of the water pump is increased by 50Hz, the pump is automatically switched to run with commercial power by a system until the pressure reaches the set value. When a small amount of water is used, the water pump is controlled by the system to track the pressure and automatically slow down for running. When the running frequency is lower than a set point, the water pump automatically stops running, and the other is switched to run in a power saving manner. Therefore, the water pressure can be kept at the set value all the time, the aim of constant water pressure is fulfilled, and electricity charges are greatly reduced.
Description
Technical field
The present invention relates to oil pipeline power saving device for water pump technical field, more particularly to a kind of oil pipeline water pump economize on electricity
Device.
Background technology
Common water pump all can not individually use typically in pipe network, and needs to be equipped with stable-pressure device, because pump working
When can with the change of the pressure of water and flow, and cause pump outlet pressure and Yang Cheng change it is common practice to
After installing water pump, in the periphery of water pump, the stability that stable-pressure device to ensure water pump water outlet is installed again, but user is come
Say and but bring unnecessary trouble, increase cost, improve the consumption of electric energy simultaneously.
Content of the invention
The invention mainly solves the technical problem of providing a kind of oil pipeline power saving device for water pump, can be according to supplying water system
The present situation of system, real-time regulation utilizes equipment, energy-saving.
For solving above-mentioned technical problem, one aspect of the present invention is: provides a kind of oil pipeline water pump section
Electric installation is it is characterised in that include: power supply, catalyst, power saving apparatus, motor, pid controller and water pump；
One tunnel output of described power supply is exported to motor by catalyst, node system, separately leads up to catalyst and directly exports
To motor；
On described motor, current voltage characteristics harvester is set, described water pump arranges flow sensor, described water tank is arranged
Pressure transducer；Described current voltage characteristics harvester, flow sensor, the signal output of pressure transducer collection are controlled to pid
Device processed, the outfan of described pid controller connects described power saving apparatus and catalyst respectively.
Preferably, described motor adopts frequency conversion motor.
Preferably, described power saving apparatus outfan arranges converter.
It is different from the situation of prior art, the invention has the beneficial effects as follows:
1st, can be according to the hydraulic pressure in water pump outfan water flow velocity, the current-voltage characteristic of motor and water tank come real-time regulation electricity
The running status of machine, energy-saving consumption-reducing.
2nd, can effectively be controlled using frequency conversion motor and start instantaneous voltage change to electrical network and equipment during startup
Impact.
Brief description
Fig. 1 is the schematic diagram of embodiment of the present invention oil pipeline power saving device for water pump.
Specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation describes it is clear that described embodiment is only a part of embodiment of the present invention, rather than whole embodiments.It is based on
Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under the premise of not making creative work
Embodiment, broadly falls into the scope of protection of the invention.
There is provided a kind of oil pipeline power saving device for water pump it is characterised in that including: power supply, catalyst, power saving apparatus, electricity
Machine, pid controller and water pump；
One tunnel output of described power supply is exported to motor by catalyst, node system, separately leads up to catalyst and directly exports
To motor；
On described motor, current voltage characteristics harvester is set, described water pump arranges flow sensor, described water tank is arranged
Pressure transducer；Described current voltage characteristics harvester, flow sensor, the signal output of pressure transducer collection are controlled to pid
Device processed, the outfan of described pid controller connects described power saving apparatus and catalyst respectively.Described motor adopts frequency conversion motor.
Described power saving apparatus outfan arranges converter.
In specific implementation process, described oil pipeline power saving device for water pump adopts microcomputer-recognized intelligent to control, built-in special
Pid actuator, when the running frequency of water pump raises 50hz, pressure is also less than setting value, and now this pump is switched to by system automatically
Civil power runs, and until pressure reaches setting value, when water consumption is few, system controls water pump to follow the tracks of the automatic fall-back of pressure, when
Running frequency low to set point when, be automatically stopped this pump operation, another be converted to power-saving running it is ensured that hydraulic pressure is protected all the time
Hold in setting value, so reach the purpose of water pressure invariableness, also save a large amount of electricity charge spendings.
The foregoing is only embodiments of the invention, not thereby limit the present invention the scope of the claims, every using this
Equivalent structure or equivalent flow conversion that bright description and accompanying drawing content are made, or directly or indirectly it is used in other related skills
Art field, is included within the scope of the present invention.
