The utility model embodiment discloses a kind of cooling water recovery device, can realize the object of Coolers envelope and recovery cooling water, neither affects also saving water resource of on-site sanitation, by the cooling processing of immersion type, can accomplish evenly cooling, good cooling results, the working life of prolongation machine envelope.
Refer to Fig. 1 and Fig. 2, in the utility model embodiment, embodiment of a kind of cooling water recovery device comprises:
Water shutoff cylinder 1, oil sealing 2, intake pipe 3, outlet pipe 4 and collection box 5.
This water shutoff cylinder 1 is hollow tubular structures, and the machine that is installed on centrifugal pump is sealed up, and the pump shaft 12 of this centrifugal pump is through on this water shutoff cylinder 1 central axis in this water shutoff cylinder 1.This water shutoff cylinder 1 can be weldless tube, adopts integrated preparation process to complete, and does not have gap or jointing edge.
This water shutoff cylinder 1 is provided with water intake 8 and water outlet 9.It should be noted that, can realize different water delivery effects by the size separately that water intake 8 and water outlet 9 are rationally set.For example: the diameter of water intake 8 is 2D, the diameter of water outlet 9 is D, and the size of water outlet 9 is the half of water intake 8 sizes.In the time that the speed of water delivery is enough, the water intake velocity of this water shutoff cylinder 1 can reach the twice of water speed, therefore can in a short period of time the inner chamber of water shutoff cylinder 1 be filled, this design fill with rapidly water-cooled machine envelope for needs and pump shaft 12 very applicable.Hypothesis again, the diameter of water intake 8 is d, and the diameter of water outlet 9 is 2d, and the size of water intake 8 is the half of water outlet 9 sizes.In the time of water delivery, the ball valve 10 that need to first close on outlet pipe 4 seals water outlet 9, fills water, toward the inner chamber of this water shutoff cylinder 1 in the time of needs draining, water outlet 9, because larger than water intake 8, therefore can discharge the water in water shutoff cylinder 1 in the situation that water intake 8 does not stop into water.
One end of this water shutoff cylinder 1 is sealed envelope by this machine, and the other end is sealed by this oil sealing 2.
The water intake 8 of this water shutoff cylinder 1 is connected with this intake pipe 3, and the water outlet 9 of this water shutoff cylinder 1 is connected with this outlet pipe 4.
These intake pipe 3 one end are connected with this water intake 8, and the other end is connected with water source; These outlet pipe 4 one end are connected with this water outlet 9, and the other end is connected with this collection box 5.
Preferably, this oil sealing 2 is outside framework oil seal 2.
Preferably, this cooling water recovery device also comprises back-up ring 13, and this back-up ring 13 coordinates this oil sealing 2 to install, for fixing the inner chamber position of this oil sealing 2 at this water shutoff cylinder 1.
Preferably, this machine package is drawn together machine envelope stationary ring 6 and machine envelope rotating ring 7.
Preferably, this cooling water recovery device also comprises ball valve 10; This ball valve 10, is installed on this intake pipe 3, for controlling the flow of this intake pipe 3; And/or this ball valve 10, is installed on this outlet pipe 4, for controlling the flow of this outlet pipe 4.
Preferably, this cooling water recovery device also comprises point inspection device 11, and this point inspection device 11 is installed on this outlet pipe 4, for checking flowing of these outlet pipe 4 cooling waters; This point inspection device 11 is provided with see-through window.The position that this point inspection device 11 is installed is higher than the position of this collection box 5.Be understandable that, staff can observe by this see-through window the situation of current in point inspection device 11, whether thereby can learn in outlet pipe 4 has cooling water flowing, avoid owing to cannot learning whether there is water in water shutoff cylinder 1, and do not carry water quench machine envelope in water shutoff cylinder 1, thereby the situation that causes machine envelope to be damaged.Therefore in the ordinary course of things,, carry cooling water in water shutoff cylinder 1 in, outlet pipe 4 can be discharged cooling water in collection box 5 simultaneously.And the position of this point inspection device 11 is can certainly to flow back in collection box 5 by the cooling water of this point inspection device 11 in order to make higher than the position of this collection box 5, reach the object of saving energy under Action of Gravity Field.
For ease of understanding, will describe the working procedure of this cooling water recovery device in detail below, understand incorporated by reference to Fig. 1 and Fig. 2:
A: first open water source, cooling water is injected in water shutoff cylinder 1 by intake pipe 3.If water intake 8 is greater than water outlet 9, can in the situation that not closing water outlet 9, in water shutoff cylinder 1, inject cooling water; If water intake 8 is not more than water outlet 9, needs water outlet 9 first to close, then inject cooling water in water shutoff cylinder 1.
B: in the process of injecting cooling water, the water level in water shutoff cylinder 1 can slowly rise, and water fills up until the inner chamber of water shutoff cylinder 1 is cooled, and now, if water outlet 9 is being closed, water outlet 9 is opened; If water outlet 9 is being opened, without comprehending.
C: if it should be noted that machine envelope and pump shaft 12 are carried out in cooling process, find the excessive velocities of water outlet, can regulate by the ball valve 10 on outlet pipe 4, water-outlet quantity and inflow are maintained an equal level.
D: if water outlet 9 is less than water intake 8, fill after cooling water at the inner chamber of water shutoff cylinder 1, the water intake velocity of water intake 8 can slowly decline because the pressure of inner chamber increases, until reach balance with the water speed that goes out of water outlet 9.
E: to machine envelope and pump shaft 12 cooling after, close water source, water intake 8 stops into water, water outlet 9 is all transported to the cooling water in the inner chamber of water shutoff cylinder 1 in collection box 5 by outlet pipe 4, realizes the object of cooling water recovery.
F: in whole process, collection box 5 is receiving outlet pipe 4 always and carrying the cooling water of coming, and has ensured effective recovery of water resources.
G: collection box 5 can be transmitted back to the cooling water of these recovery in water source after cooling water is reclaimed again, realizes recycling of water resources.
Above a kind of cooling water recovery device provided by the utility model is described in detail, for one of ordinary skill in the art, according to the utility model embodiment's thought, all will change in specific embodiments and applications, in sum, this description should not be construed as restriction of the present utility model.
