The present invention will be described in detail below with reference to the embodiments with reference to the attached drawings.
Referring to fig. 1, in the embodiment of the utility model, the numerical control constant pressure integrated water supply equipment comprises a pressure stabilizing tank body 1, a plurality of pump sets 7 are connected and communicated in parallel on the pressure stabilizing tank body 1, one end, far away from the pressure stabilizing tank body 1, of each pump set 7 is connected with an equipment water outlet pipe 3, and a pressure protection device 4 and a pressure monitoring device 5 are installed on the equipment water outlet pipe 3.
And a control system 2 is also arranged between the pressure stabilizing tank body 1 and the equipment water outlet pipe 3.
And the pressure stabilizing tank body 1 is also provided with an equipment water inlet pipe 6.
The working principle of the utility model is as follows:
1) the equipment directly links municipal pipe network, carries to the user end through the pump package pressurization, and the steady voltage jar body 1 plays steady voltage and compensating action to the equipment exit, also is the precondition that the water pump can get into the sleep simultaneously, utilizes the minimum nature of the compressibility of water, stores up water with external force in the jar, and gas receives compression pressure and risees, and the compressed gas inflation that disappears when external force can get rid of water. Because the compression ratio of water is far less than that of gas, when the pipe network has small-flow leakage, the pressure can be greatly reduced, and the water pump can be frequently started. By using the pressure stabilizing tank body 1, water can be stored in the pressure stabilizing tank body 1 under the pressure rich in the equipment outlet, the outlet pressure compensation process is carried out by the stored pressure when water is used at a small flow, the water use requirement is met, and the water pump unit is not started in the process, so that the idle work loss caused by energy is avoided;
2) when municipal water supply pipe network pressure was not enough, the steady voltage jar body 1 came water to the municipal pipe network and plays the effect of compensation and steady voltage, and the steady voltage jar body 1 compensation equipment outlet pressure sends water to the water consumption point, accomplishes the water supply process. In the whole water supply process, the original pressure of a municipal water supply network can be utilized to a greater extent, and the working pressure of the water pump unit is greatly reduced under the action of energy compensation of the pressure stabilizing tank body 1;
3) when the water supply system is in a water consumption peak area and the water supply quantity of the municipal water supply network is insufficient, the energy stored in the pressure stabilizing tank body 1 is used for carrying out differential compensation on the outlet of the equipment and charging the energy. Reducing the working pressure of the water pump unit;
4) when the water supply quantity of the municipal water supply network is seriously insufficient or the water supply is stopped, the pressure in the pressure stabilizing tank body 1 is gradually reduced. Pressure monitoring devices sends the signal of telecommunication, and municipal pipe network pressure is less than and sets for protection pressure, and the warning is in time shut down to equipment, avoids water supply equipment to damage, effectively protects municipal water supply pipe network. This equipment has greatly improved water supply efficiency and equipment reliability of use.
The water supply equipment integrates a control system integrally to the equipment to realize real numerical control frequency conversion constant pressure integrated water supply equipment, the water supply equipment can be directly connected with a municipal water supply network without being equipped with a water tank, and can be connected in series and superposed with water supply on the basis of the residual pressure of the municipal pipe network to ensure that the pressure of the municipal pipe network is not less than the set protection pressure, a pressure stabilizing tank body 1 which is arranged at a water outlet of the equipment in the prior art is upgraded, a water inlet of the pressure stabilizing tank body 1 is connected with an equipment water outlet pipeline and is hidden behind a flow stabilizing tank, and the integral attractiveness of the equipment is improved. The effective volume is increased, the energy storage capacity is better when the equipment works normally, and the energy compensation can be better carried out on the outlet of the equipment.
This equipment with control system whole integrated to equipment on and equipment can directly link municipal pipe network, it is excessive that middle water tank, water tower of need not, realizes real numerical control constant voltage integration water supply equipment. Thereby numerical control constant voltage water supply system realizes the hydraulic closed loop control (PID) of pipe network through the rotational speed of the output frequency automatically regulated water pump motor of control converter, makes automatic the invariable pressure value in the settlement of water supply system: when the water amount is increased, the frequency is increased, the rotating speed of the water pump is increased, and the water supply amount is correspondingly increased; when the water consumption is reduced, the frequency is reduced, the rotating speed of the water pump is reduced, the water supply amount is correspondingly reduced, the working state of the switching equipment is quickly adjusted according to the water demand, the control precision of the set pressure and the actual pressure is less than or equal to 0.01Mpa, and the water is supplied by using the amount of water, so that the requirements of water supply efficiency users on the water pressure and the water amount are ensured, and the purposes of improving the water supply quality and the water supply efficiency and efficiently saving energy are achieved. The equipment does not need to build a high-level water tank or a water tower, so that the water quality has no secondary pollution, and the water is healthier. The equipment rotates the pump set at regular time and starts and stops firstly, so that the service life of the pump set is prolonged, and the maintenance cost is reduced. The volume of the pressure stabilizing tank body 1 is increased, the pressure stabilizing tank body is arranged at the rear of the equipment and connected with the water outlet header pipe, the outlet water quantity and the pressure are balanced, the small-flow pressure maintaining function is achieved, the water supply pressure is automatically compensated according to the outlet pressure, the working pressure of the pump set is reduced, the service life of the pump set is prolonged, and the energy saving performance and the safety of the water supply equipment are improved. Has important significance for improving the water supply efficiency
