Description

technical field [0001] The invention belongs to the field of water supply equipment control, in particular to an intelligent frequency conversion constant pressure automatic water supply equipment. Background technique [0002] The pressurized water supply system includes water towers, high water level tanks, pressure tanks and other implementation methods. The frequency conversion and constant pressure automatic water supply equipment in the water supply system is used to adjust the operation of the water pump through frequency conversion according to the change of water consumption in the water supply pipe network, so as to achieve stable water head output at the water outlet of the equipment, such as a water supply method with stable pressure head.

Problems solved by technology

[0003] The existing frequency conversion constant pressure automatic water supply equipment, on the one hand, due to the vibration generated by the operation of water pumps and water heads, conventional shock absorption measures are difficult to fully suppress the vibration of the equipment, thus affecting the normal service life of equipment parts, and in some cases severe vibration , and even directly lead to damage and failure of internal parts; on the other hand, in the case of partial or partial failure of equipment components, such as winter and other low working environment temperatures, the abnormal operation of equipment caused by frostbite of water supply equipment components , will affect the overall dynamic balance of the equipment and produce severe vibration, which will lead to the complete paralysis of the water supply equipment and affect the normal water supply

In the prior art, there are shock-absorbing measures for adding shock-absorbing and damping devices to the frequency conversion constant-pressure automatic water supply equipment and the external fixed base, but the existing hydraulic and electromagnetic shock absorbers are difficult to achieve a balance between cost and performance, and the simple structure of the shock The damping device will be replaced frequently, which will increase the user's investment and operating costs.
