Abstract
A tank type pressure-superposed series high-set steady flow tank water supply system comprises: the system comprises a municipal water supply pipe network, a low stationary flow tank, a water supply pump set, a user pipe network, a high stationary flow tank and a control cabinet; the low stationary flow tank is sequentially provided with a water inlet pressure sensor and a flow controller along a water inlet pipeline, and the tank body of the stationary flow tank is provided with two air pressure water tanks; the water outlet pipeline of the municipal water supply network is connected with a flow controller at the front end of the water inlet pipeline of the low stationary flow tank; the water supply pump set, the user pipe network and the high-level steady flow tank are sequentially connected through pipelines. The utility model discloses be applied to municipal pipe network flow and satisfy, the not enough user pipe network of pressure, when realizing not having the negative pressure water supply, municipal pipe network stacks in water supply pump package and presses the unnecessary kinetic energy of water supply and store in high stationary flow jar, waits to store sufficient back water pump stop function, and high stationary flow jar is supplied water with the mode top-down that flows automatically, and the energy obtains the release to sparingly supply water pump package power loss.
Description
Technical Field
The utility model relates to a water treatment field, in particular to pot-type does not have negative pressure water supply equipment.
Background
The pot-type pressure-superposed water supply system is suitable for a place where the flow of a primary water supply network is sufficient, the water demand of a secondary pipe network is met, and the water supply pressure of the primary pipe network cannot meet the water pressure requirement of a secondary pipe network user. For satisfying the most unfavorable water supply demand of user's pipe network, the water supply pump package need provide supplemental pressure when a pipe network pressure is not enough, superposes with a water supply network and presses and supplies water, has produced unnecessary kinetic energy among the water supply process, and this part kinetic energy if can't retrieve, will cause the energy consumption extravagant.
SUMMERY OF THE UTILITY MODEL
The purpose of the present invention is to solve at least one of the technical drawbacks.
Therefore, an object of the utility model is to provide a tank-type is folded and is pressed and concatenate high stationary flow jar water supply system that puts, include: the system comprises a municipal water supply pipe network, a low stationary flow tank, a water supply pump set, a user pipe network, a high stationary flow tank and a control cabinet;
the low stationary flow tank is sequentially provided with a water inlet pressure sensor and a flow controller along a water inlet pipeline, and the tank body of the stationary flow tank is provided with two air pressure water tanks;
the water outlet end of the water supply pump set is provided with a water outlet pressure sensor;
a liquid level meter is arranged in the high-position steady flow tank body;
the municipal water supply network water outlet pipeline is connected with the flow controller at the front end of the low stationary flow tank water inlet pipeline;
the low stationary flow tank, the water supply pump set, the user pipe network and the high stationary flow tank are sequentially connected through pipelines;
the control cabinet is respectively in circuit connection with the water inlet pressure sensor, the flow controller, the water supply pump group, the water outlet pressure sensor and the liquid level meter.
When the system is operated, the water inlet pressure sensor monitors the water pressure of the municipal water supply network, when the water inlet pressure is insufficient, the flow controller reduces the water supply flow, and therefore the insufficient flow is generated and is partially supplied by the low stationary flow tank; the low steady flow tank air pressure water tank is used for stabilizing the water pressure of the directional water supply pump set. The water supply pump set operates in a frequency conversion mode, and except that water is supplied to the user pipe network and water pressure of a water point is not utilized, excess water is stored by the high-position steady flow tank; when the liquid level meter monitors that the water stored in the high stationary flow tank reaches the upper limit, the water supply pump set stops running, and water is supplied to the user pipe network from top to bottom by the high stationary flow tank; and when the liquid level of the high stationary flow tank reaches the lower limit, the water supply pump set starts water supply, and the operation is repeated in a circulating mode.
The utility model has the advantages and positive effects that: when the device is used for a user pipe network with the municipal pipe network meeting the flow and insufficient pressure, negative-pressure-free water supply is realized, redundant kinetic energy of the municipal pipe network and the water supply pump set during pressure-superposed water supply is stored in the high stationary flow tank, the water pump stops running after sufficient storage, the high stationary flow tank supplies water from top to bottom in a self-flowing mode, and the energy is released, so that the electric energy loss of the water supply pump set is saved.
