The utility model discloses be applied to and satisfy municipal pipe network flow, pressure is not enough, the little user pipe network in pump house place area uses this equipment, and the unnecessary kinetic energy of pump package pressure-superposed water supply is stored in high stationary flow jar in municipal pipe network and delivery pipe, treats to store sufficient back water pump stop function, and municipal water supply network supplies water with high stationary flow jar with the stack mode through bypass line, and high stationary flow jar stores the energy and obtains the release to pump package electric energy loss in saving the delivery pipe.
Description
Technical Field
The utility model relates to a water treatment field, in particular to no negative pressure water supply equipment of pump in the pipe.
Background
The pump pressure-superposed water supply in the pipe is suitable for the situation that the flow of a primary water supply pipe network is sufficient, the water demand of a secondary pipe network is met, the water supply pressure of the primary pipe network cannot meet the water pressure requirement of a secondary pipe network user, and the field of a pump room is small. 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 pump is folded and is pressed and concatenate high stationary flow jar water supply system in pipe, include: the system comprises a municipal water supply pipe network, a pump group in the water supply pipe, a user pipe network, a high-level steady flow tank and a control cabinet;
the pump set in the water supply pipe is formed by connecting more than two pump branches in the pipe and a bypass pipe branch in parallel;
the pump-in-pipe branch comprises a pressure compensator, a water inlet pressure sensor positioned at the water inlet end of the pressure compensator, an anti-negative pressure valve positioned at the water outlet end of the pressure compensator and a water outlet pressure sensor;
a liquid level meter is arranged in the high-position steady flow tank body;
the municipal water supply pipe network, the pump group in the water supply pipe, the user pipe network and the high-position steady flow tank are sequentially connected through pipelines;
the control cabinet is respectively connected with the pressure compensator, the water inlet pressure sensor, the negative pressure prevention valve, the water outlet pressure sensor and the liquid level meter through circuits.
When the system is operated, when the pressure of a municipal water supply network is greater than the pressure required by a user pipe network, or the pressure of the municipal water supply network is less than the pressure required by the user pipe network and the liquid level of the high stationary flow tank is higher than a set lower limit, the pressure compensator enters a dormant state, and the bypass pipeline and the high stationary flow tank are superposed to supply water to the user pipe network; and when the liquid level of the high stationary flow tank is lower than a set lower limit and the water outlet pressure sensor monitors that the water pressure value of the user pipe network is lower than a set value, starting the pressure compensator until the high stationary flow tank reaches a set upper limit of the liquid level, and repeating the steps in such a way.
The utility model has the advantages and positive effects that: the device is used for a user pipe network with the advantages of meeting the flow of a municipal pipe network, being insufficient in pressure and small in area of a pump room, redundant kinetic energy of superposed water supply of the pump set in the municipal pipe network and a water supply pipe is stored in a high-level flow stabilizing tank, the water pump stops operating after sufficient storage is waited, the municipal water supply pipe network supplies water to the user pipe network in a superposition mode through a bypass pipeline and the high-level flow stabilizing tank, the high-level flow stabilizing tank stores energy and releases the energy, and therefore the electric energy loss of the pump set in the water supply pipe is saved.
