Description

Integrated series parallel type multi-functional drainage unit

Technical field

The utility model relates to the composite set of a plurality of pumps, but the multi-functional drainage unit of particularly a kind of incorporate series-parallel connection (every group of two water pumps series connection, two groups of parallel connections) operation.

Background technique

Water pump all has in fields such as agricultural, industry very widely to be used, and technology reaches its maturity.But under many circumstances, the separate unit water pump can't satisfy the requirement of real world applications, so just need the joint work mode of water pump.When external load altered a great deal, the amplitude of variation of flow was also very big, in order to reach the effect of water pump economical and energy saving, often adopted two or several parallel connection of pumps work, increased flow, adapted to the requirement that external load changes; Because the influence of extraneous water level, a water pump does not often satisfy high-lift needs, in order to address this problem, generally adopts two above pressure operations, utilize multistage water lift mode to improve lift, guaranteed high-lift effectively to export the needs of more flow.The change of external environment means the transition of pump operating condition, and lift height, high powered water pump volume that flow is big are big, heavy, the down-hole is installed extremely inconvenient, in the prior art, the transition of operating mode just requires water pump to carry out the conversion of serial or parallel connection working method, because water pump removes and installs difficulty under the draining environment, wastes time and energy, influence the ageing of draining, also reduced the working efficiency of water pump.

In the known techniques, patent CN 101236708A discloses a kind of desk-top water pump series-parallel connection integrated experimental bench with upright screen, this Laboratory Furniture can be by the switching and the adjustment of valve, and the change of the switching of the realization water pump series-parallel connection method of operation and flow, lift is convenient to operation simultaneously, observes and is understood; Patent CN 201321993Y discloses a kind of Submerged Motor Pumps that adapts to the operating condition-jumping of different operating modes, this Submerged Motor Pumps can open and close by the independent of control valve to three, realize the Submerged Motor Pumps conversion of the series, parallel work pattern of pump up and down, can realize the operating condition-jumping of Submerged Motor Pumps, improve ageing.Yet above-mentioned two patent CN101236708A and CN 201321993Y have all adopted the parallel running mode and the series operation mode of water pump, do not relate to the method for operation that adopts series parallel connection to mix, and the method for operation that water pump series-parallel connection mixes both can be used for high-lift water-discharged operating mode, also can be used for the operating mode of big flow draining.

The model utility content

In order to solve the prior art deficiency, but the purpose of this utility model is to provide a kind of multi-functional drainage unit of incorporate series-parallel connection operation, this model utility is when carrying out draining, but the on off state of remote centralized control of pump group and valve, realize single pump, two also, two strings, three also, three strings, four also, behind four strings, two series connections of pumps again and the quick switching of the eight kinds of methods of operation of allying the communists, reach the purpose of regulating lift and water displacement.This model utility is not limited by operating environment, can be used for speedily carrying out rescue work, field such as fire-fighting, irrigation, water supply, and is safe and reliable, economical rationality.

The purpose of this utility model can realize by following technique measures:

Integrated series parallel type multi-functional drainage unit of the present utility model, this device comprises water pump group, valve, pipe-line system, wherein the water pump group is made up of the water pump of four same model; Valve and water pump group are integrated by the pipe-line system seal combination; According to hole diameter or space size, pipe-line system can be adjusted the arrangement and the spatial position of water pump group by conversion, combination, to adapt to different operating environments; This model utility is when carrying out draining, by the control apparatus of operation with this model utility networking, but the on off state of remote centralized control of pump group and valve, realize the real-time series-parallel connection method of operation, promptly carry out single pump, two also, two strings, three also, three strings, four also, behind four strings, two series connections of pumps again and the quick switching of the eight kinds of methods of operation of allying the communists, reach the purpose of regulating lift and water displacement,, realize the draining of efficient energy-saving ground as far as possible to adapt to different operating modes.
