Pot-type pipe network pressure-superposed water supply device

Abstract

The invention discloses a pot-type pipe network pressure-superposed water supply device which mainly consists of a flow stabilization tank, a negative pressure eliminator, a water-free detection device, water pumps, an air pressure water tank and a control cabinet. The flow stabilization tank is connected with a tap water inlet pipe, the tap water inlet pipe is provided with a remote transmitting pressure gauge, the negative pressure eliminator is arranged on the flow stabilization tank, the water-free detection device is arranged in the flow stabilization tank and used for detecting the water level of the flow stabilization tank, an emptying valve is arranged at the bottom of the flow stabilization tank to facilitate maintenance, outlet water of the flow stabilization tank flows into a water outlet header pipe through the water pumps, the remote transmitting pressure gauge and the air pressure water tank are arranged on the water outlet header pipe, the water outlet header pipe is connected to a water using point through a user pipe network, and the control cabinet is used for detecting water inlet pressure, the water level of the flow stabilization tank and controlling automatic start and stop, switching, number increase or decrease and viable-frequency constant-pressure water supply of the water pumps. The pot-type pipe network pressure-superposed water supply device has the advantages of being simple in structure, small in occupied area, low in cost, convenient to install and maintain, stable and reliable in work and the like and being capable of utilizing the tap water inlet pressure to achieve energy-saving effect.

Description

technical field [0001] The invention relates to the technical field of secondary water supply, in particular to a tank-type pipe network superimposed water supply equipment. Background technique [0002] With the increasing number of high-rise buildings, secondary water supply is becoming more and more common. The secondary water supply is usually to put tap water into a pool or a water tank, and then use a water pump to draw water from the pool or tank to pressurize it for water point application. The functions of the water pool or water tank in the system are: one is to store water, and the other is to eliminate the negative pressure effect of the water pump directly connected to the water supply network in series. However, due to the large volume of pools and water tanks, installation and maintenance are inconvenient, and water pollution and other problems are easily caused. Therefore, in recent years, a pipe network superimposed water supply method that cancels pools an...

Problems solved by technology

However, due to the large volume of pools and water tanks, installation and maintenance are inconvenient, and water pollution and other problems are easily caused. Therefore, in recent years, a pipe network superimposed water supply method that cancels pools and tanks and directly connects water pumps in series has appeared on the market. The water supply method is mainly composed of a steady flow compensator, vacuum suppressor, water pump, etc., but its structure is relatively complicated and the cost is high, and it needs to be maintained and managed by professional and technical personnel of the manufacturer. If a failure occurs, it is not conducive to timely repair
