Description

A kind of constant pressure water supply system

Technical field

This utility model relates to water system, especially relates to a kind of constant pressure water supply system.

Background technology

At present, constant pressure water supply mode mainly has air pressure tank mode and frequency control way.Compared with air pressure tank mode, frequency conversion Mode of speed regulation has the saving advantage such as the energy, stable and reliable operation, and economic benefit is obvious with social benefit, becomes constant pressure water supply The main flow of mode.

The most domestic have many companies doing the engineering of constant pressure water supply, but in the selection of controller, all using can Programmable controller, in the actual application of constant pressure water supply, converter, normally only as actuator, needs pressure controller Realize closed loop control, and a converter only drives a water pump assembly, drag multiple water pump machines almost without a converter The situation of group, thus the cost of investment of controller and converter is high.Some system can not change motor according to actual water requirements Input quantity and working condition, thus operational efficiency is the highest, and the dynamic of whole system, stability and anti-interference etc. are many The comprehensive technical indexes of aspect is far from reaching the requirement of all users.

Utility model content

The technical problems to be solved in the utility model is to overcome the deficiency in prior art, it is provided that a kind of simple in construction, confession Water system flexibility is strong, automaticity is high；Good energy-conserving effect simultaneously, working stability, security performance is high.

For solving the problems referred to above, this utility model adopts the following technical scheme that

A kind of constant pressure water supply system, including PLC, storage power down module, human-machine exchange module, group of motors and water pump Group, described storage power down module is connected with PLC with inter-person exchange module, be provided with in described human-machine exchange module by Key module and display module, described PLC connects A/D module one and A/D module two, and described A/D module one connects to be had Sensor, described sensor connects water pipe pipe network, and described A/D module two connects converter, described converter and group of motors Being connected, described group of motors is connected with water pump group, and described water pump group is connected with water pipe pipe network.

As preferably, described PLC control module is provided with PID constant voltage adjustment module, is advantageously implemented constant voltage regulation.

As preferably, described sensor uses Y2D-F model pressure transducer, and Y2D-F pressure transducer has sensitivity Height, precision overload capacity high, anti-are strong.

As preferably, described converter uses 5K-CH model converter, it is possible to effectively and YVP serial motors with the use of, It is fully achieved technological requirement.

As preferably, described display module uses light-emitting diode display, mainly system information is shown over the display.

As preferably, described key-press module uses independent keyboard, is mainly used in setting hydraulic pressure initial value and according to reality Border situation changes hydraulic pressure value.

As preferably, described group of motors uses YVP serial motors, it is possible to be adjusted according to practical situation.

As preferably, the chip of described A/D module one and A/D module two uses X5045 model chip, X5045 model core It is high that sheet has integrated level, and price is low.

The beneficial effects of the utility model are: owing to being provided with PID constant voltage adjustment module in PLC, it is possible to realize Constant voltage regulates；Owing to being provided with converter, and a converter can control multiple electric motors and run, and reduces cost of investment；Due to It is provided with sensor, effectively ensure that system reliability of operation and stability；Owing to being provided with human-machine exchange module, can be to water It is pressed with effect to be monitored and controlled in real time；Simultaneity factor saves the energy, and regulating power is big, has broad application prospects and good Social benefit.
