A kind of pump cooling water circulating device
Technical field
The utility model relates to a kind of pump cooling water circulating device.
Background technique
Pump is a kind of important conveying equipment for fluid substances, uses very extensive in every profession and trade.Pump often will feed the cooling water that meets water quality requirement in mechanical seal place in operation process.Cooling water mainly plays two aspects: the one, and cooling, the 2nd, sealing, the use of cooling water can improve the reliability of pump sealing apparatus and can prolong the working life of seal arrangement.
At present, pump generally adopts the pattern of one-to-many in the factory with cooling water: i.e. the corresponding a plurality of waters of circulating water central treating station workshop middlely connects by pipeline.The feedwater usually by pump or the form of pressing certainly be delivered to each water workshop from the circulating water central treating station, supply pipe is cross-over pipe or underground pipe; Backwater is by pressing certainly or the pumping form is delivered to the circulating water central treating station from each water workshop, and return pipe is generally underground pipe.For integrated mill, when waterline was longer, traditional plumbing mode of pump cooling water was all very high in the expense of aspects such as equipment investment, pipeline investment, power consumption, pipe laying and maintenance.
The model utility content
Technical problem to be solved in the utility model is, provide a kind of simple in structure, equipment investment is little, use the low pump cooling water circulating device of energy consumption, to overcome deficiency of the prior art.
The technical solution of the utility model: the outlet pipe of aqua storage tank and the cooling water inlet of transfer pump link together, and the coolant outlet of transfer pump and the intake pipe of header tank link together, and header tank is connected with aqua storage tank by the cooling water transfer pump; The mounting point of aqua storage tank is higher than transfer pump, and the mounting point of transfer pump is higher than header tank.
The intake pipe of described aqua storage tank connects the domestic water in the workshop.
In the described aqua storage tank float valve is installed, when the liquid level in the aqua storage tank reduced, float valve was opened moisturizing automatically, and float valve was closed automatically and stopped to supply water after liquid level was recovered.
Described transfer pump be single or multiple cooling water inlets, the outlet be connected in parallel respectively transfer pump.
Compared with prior art, the utility model is applicable to the cooling water circulation of the transfer pump in single workshop, utilizes the drop between aqua storage tank, transfer pump, the header tank and the pumping of cooling water transfer pump to carry out the cooling water circulation.The utility model is simple in structure, pipe laying is apart from weak point, thereby equipment investment is little; Because the single roundtrips of cooling water is short, thereby use energy consumption low.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model.
Embodiment
Embodiment of the present utility model: at first, float valve 4 is installed in aqua storage tank 1, and (float valve 4 was opened moisturizing automatically when the liquid level in the aqua storage tank 1 reduced, float valve 4 was closed automatically and is stopped to supply water after liquid level was recovered), the domestic water in aqua storage tank 1 intake pipe and the workshop is coupled together; Then, aqua storage tank 1 is fixed on the position that is higher than transfer pump 2, header tank 3 is fixed on the position that is lower than transfer pump 2; At last, the outlet pipe of aqua storage tank 1 and the cooling water inlet of transfer pump 2 are linked together, the coolant outlet of transfer pump 2 and the intake pipe of header tank 3 are linked together, header tank 3 is coupled together by cooling water transfer pump 5 and aqua storage tank 1.
If a plurality of transfer pumps 2 are arranged in the workshop, then the cooling water inlet with each transfer pump 2 is connected on the outlet pipe of aqua storage tank 1, and the coolant outlet of each transfer pump 2 is connected on the intake pipe of header tank 3.
