Abstract
The utility model provides a self-circulation water cooling system for bump mechanical seal, belongs to the water cooling device field of bump mechanical seal, in particular to an improvement of mechanical seal for pump. The utility model comprises a bump body and a water cooling system. The system is characterized in that an internal circulation impeller (5) is installed on a cooling water inlet (2) inside the mechanical seal base (3) of the bump body. Compared with the prior art, the water consumption is less, and the effective cooling can be processed when the water amount is just 30 liters in the water tank. Because the internal circulation impeller is arranged, the self-circulation can be realized by the rotation of the impeller, and the cooling effect is quite good. The self-circulation water cooling system solves the problem of needing pressure water in the prior art, and saves a great deal of water resources.
Description
Technical field
The self-circulating water cooling system of mechanical seal for pump belongs to the water cooling plant field of pump mechanical sealing.It specifically is improvement to the mechanical seal of pump.
Background technique
Mainly by there being the outer of pressure for cooling liquid the heat that rubbing surface produces to be taken away, the cooling liquid of the pressure that provides is generally water in the cooling of the mechanical encapsulation devices of China.For guaranteeing the normal use of mechanical encapsulation devices, the user need increase cooling water recirculation system, not only increases investment, and the fault point is increased.And present used cooling equipment, cooling water not can be recycled, and in order to guarantee the good of cooling effect, often needs a large amount of cooling waters, has wasted precious water resource.For western water-deficient area, more can't guarantee the supply of cooling water, often take place to damage because of lack of water causes mechanical seal.
The model utility content
The technical problems to be solved in the utility model is: overcome the deficiencies in the prior art, but the self-circulating water cooling system of the few automatic cycle of a kind of water consumption, mechanical seal for pump that cooling effect is good is provided.
The technological scheme that its technical problem that solves the utility model adopts is: the self-circulating water cooling system of this mechanical seal for pump, comprise the pump housing, cooling water recirculation system is characterized in that: the cooling water intake place installs interior circulation impeller additional, overhead cooling water water tank in the mechanical sealing base of the pump housing.
The spring that mechanical sealing base adopts is a disk spring.
Cooling water intake and coolant outlet stagger.
Compared with prior art, the beneficial effect that the self-circulating water cooling system of the utility model mechanical seal for pump is had is: water consumption is few, and water tank is filled 30 premium on currency and can effectively be cooled off; Because interior circulation impeller is set, but impeller rotation automatic cycle, and cooling effect is good, and having solved prior art needs press water, can not use tap water, gets final product with the water in the overhead water tank.Save great lot of water resources.
Description of drawings
Fig. 1 is the self-circulating water cooling system structural representation of the utility model mechanical seal for pump;
Fig. 2 is the self-circulating water cooling system schematic diagram of the utility model mechanical seal for pump.
Fig. 1-2 is a most preferred embodiment of the present utility model.
Wherein: circulation impeller 6 holds out against screw 7 main shafts 8 coolant outlets in 1 water tank, 2 cooling water intakes, 3 sealing seats, 4 belleville springs 5.
Embodiment
Self-circulating water cooling system below in conjunction with 1 pair of mechanical seal for pump of the present utility model of accompanying drawing is described further:
With reference to accompanying drawing 1:
The self-circulating water cooling system of this mechanical seal for pump is by water tank 1, cooling water intake 2, sealing seat 3, belleville spring 4, interior circulation impeller 5, hold out against screw 6, main shaft 7, coolant outlet 8 and form.Be to improve on the basis of original mechanical seal of using on the pump to prior art 80ZJA-I-A36 model.In the prior art, helical spring is adopted in mechanical seal, but the helical spring volume is big, and the helical spring on the main shaft 7 changes belleville spring 4 into, and circulation impeller 5 is rotated with main shaft 7 in main shaft 7 and cooling water intake 2 corresponding parts install additional.
With reference to accompanying drawing 1-2:
Working principle and working procedure are as follows:
When main shaft 7 rotations, circulation impeller 5 rotations in driving; Because action of centrifugal force, water flows to outer rim by the inboard, under the constraint of mechanical sealing base 3, is flowed out by coolant outlet 8.And the cavity that causes is thus replenished by new cold water.On put water tank 1 generally by installing in 1 meter, the theoretical head of interior circulation impeller 5 is 2 meters, in conjunction with different spaces and rotating speed, can calculate suitable radius and width.
The rotating speed of this pump is that per minute 1480 changes, and the external diameter of interior circulation impeller 5 is defined as 125 millimeters of ￠ through test of many times, and width is 5 millimeters.When effective 1/4 ＂ of transporting water, water tank 1 also can be realized the circulation of cooling liquid in two meters height.Surpassed expected effect.Through using, can satisfy it does not have water-cooled condition from the beginning.
Claims (3)
1, the self-circulating water cooling system of mechanical seal for pump comprises the pump housing, and cooling water recirculation system is characterized in that: the interior cooling water intake of the mechanical sealing base of the pump housing (3) (2) locates to install additional interior circulation impeller (5), overhead cooling water water tank (1).
2, the self-circulating water cooling system of mechanical seal for pump according to claim 1 is characterized in that: the spring that mechanical sealing base (3) adopts is disk spring (4).
3, the self-circulating water cooling system of mechanical seal for pump according to claim 1 is characterized in that: cooling water intake (2) staggers with coolant outlet (8).
