Abstract
The utility model discloses an automatic mechanical seal cooling system of a heating network circulating pump. The automatic mechanical seal cooling system comprises a pump cover (7), a mechanical seal (4) and a mechanical seal cavity (9), wherein an inlet end of a cooler (1) is connected with a high-pressure cavity (10) of the pump cover (7) through a pipe fitting, a filter (2), a pressure gauge (5) and a decompression valve (6), and an outlet end of the cooler (1) is connected with the mechanical seal cavity (9) through a pipe fitting. The automatic mechanical seal cooling system of the heating network circulating pump is good in cooling effect, low in energy consumption and long in service life through the mechanical seal and can be widely applied to the heating network thermal circulating pump.
Description
Technical field
The utility model relates to a kind of mechanical seal cooling system, particularly relates to a kind of pumps for hot water supply net mechanical seal automatic cooling system.
Background technique
At present, it is to be injected in the mechanical seal chamber from the outside high pressure cleaning industry water of introducing of pump that known pumps for hot water supply net mechanical seal cooling has dual mode, the first, cooling mechanical seal.Although this kind mode is cooling mechanical seal preferably, but this mode has two shortcomings: the firstth, and it needs outer for the high pressure cleaning industry water, the high pressure cleaning water of outer confession needs supporting suction booster to provide or arrange high-order water tower etc., so just expend the pumps for hot water supply net energy in addition, particularly increased extra power consumption.The secondth, the clean water of outer confession has affected the water quality of carrying.
The known pumps for hot water supply net mechanical seal of the second type of cooling is that the delivery chamber (hyperbaric chamber) from pumps for hot water supply net is drawn cooling water, after a simple gate valve, is linked in mechanical seal cavity.Although this mode has realized the sealing of auto-cooling tool, but two shortcomings are arranged also: the firstth, due in cooling water directly is incorporated into the mechanical seal chamber from the hyperbaric chamber of pump, do not have the effect of cooling mechanical seal, because the water temperature in the water temperature in hyperbaric chamber and mechanical seal chamber or the same high at all.Usually the water temperature of pumps for hot water supply net all at 90C °～150C °, therefore this type of cooling is moved under the mechanical seal hot soak condition of pumps for hot water supply net, greatly reduce by working life.The 2nd, this mode is regulated the pressure that reduces in mechanical seal cavity by gate valve, although pressure decreased, but gate valve is simultaneously having injected the discharge reduction in mechanical seal cavity, the water yield is in case reduce, the cooling effect of mechanical seal is just had a greatly reduced quality, mechanical seal reduces working life, and security of operation can not get ensureing.
The model utility content
Technical problem to be solved in the utility model is to provide that a kind of good cooling results, energy consumption are little, the pumps for hot water supply net mechanical seal automatic cooling system of mechanical seal long service life.
In order to solve the problems of the technologies described above, the pumps for hot water supply net mechanical seal automatic cooling system that the utility model provides, comprise pump cover, mechanical seal and mechanical seal chamber, cooler, filter, pressure gauge, reduction valve are connected with the hyperbaric chamber of described pump cover, and the outlet end of described cooler is connected with described mechanical seal chamber by pipe fitting.
Described pressure gauge is arranged in described reduction valve outlet.
Cross fitting is equipped with at top at described pump cover, and the outlet of described cross fitting is connected with the import of each described reduction valve respectively.
Adopt the pumps for hot water supply net mechanical seal automatic cooling system of technique scheme, its basic principle is: from pump cover delivery chamber (hyperbaric chamber), cooling water is drawn; Reduce the hydraulic pressure of cooling water by regulating reduction valve, the effect of reduction valve is decompression, but keeps the cooling water water yield constant, enters pressure in mechanical seal cavity, the seal loads pressure of Real Time Monitoring mechanical seal by the pressure gauge measurement; By filter, cooling water is filtered, make the cooling water cleaning that enters in mechanical seal cavity, guarantee that mechanical seal is not by the impurity wear damage; Reduce the temperature of cooling water by cooler, make the cooling water water temperature that enters in mechanical seal cavity reduce, improve the cooling effect of mechanical seal.
The beneficial effects of the utility model are, the first, fundamentally improved the cooling effect of pumps for hot water supply net mechanical seal, pumps for hot water supply net provides sufficient cooling water voluntarily, do not need the outer high pressure cleaning water cooling that supplies, realize the sealing of auto-cooling tool, reach energy-saving and cost-reducing purpose.The second, reduced pumps for hot water supply net mechanical seal cavity pressure and water temperature, greatly improved operating safety factor and the working life of mechanical seal, guarantee pumps for hot water supply net long-term safety reliable operation.The 3rd, the cooling water of drawing in hyperbaric chamber is by filtering, and impurity is eliminated, and has avoided mechanical seal to wear and tear because of minute impurities, the working life of prolonged mechanical sealing.
In sum, the problem such as the utility model has solved that pumps for hot water supply net mechanical seal cooling effect is poor, energy consumption is large, quick abrasion, life-span are short has improved working life of mechanical seal, has guaranteed the safe operation of pumps for hot water supply net.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
referring to Fig. 1, pumps for hot water supply net is provided with two mechanical seal chambeies 9, be provided with a mechanical seal 4 in each mechanical seal chamber 9, load onto the cross fitting 8 that is communicated with the hyperbaric chamber 10 of pump cover 7 at the top of pump cover 7, minute two-way connects respectively two the mechanical seal chambeies 9 to pumps for hot water supply net two ends, be that two outlets of cross fitting 8 are respectively by the first pipe fitting 3, the entrance point of reduction valve 6 and filter 2 and a cooler 1 links together, pressure gauge 5 is arranged in reduction valve 6 outlets, the outlet end of cooler 1 is connected by a mechanical seal chamber 9 of the second pipe fitting 11 and pumps for hot water supply net.
Referring to Fig. 1, when pump operation, the medium that pump itself is carried from the delivery chamber of pump cover 7 be hyperbaric chamber 10 by decompression, cooling and filter after automatically inject in mechanical seal chamber 9; Reduce the hydraulic pressure of cooling waters by regulating reduction valve 6, keep simultaneously the cooling water water yield constant, measure the pressure that enters in mechanical seal chamber 9, the seal loads pressure of Real Time Monitoring mechanical seal 4 by pressure gauge 5; Filter 2 filters cooling water automatically, makes the cooling waters cleaning that enters in mechanical seal chamber 9, guarantees that mechanical seal 4 is not by the impurity wear damage; Reduce the temperature of cooling water by cooler 1, make the cooling water water temperatures that enter in mechanical seal chamber 9 reduce, improve the cooling effect of mechanical seal 4.
The utility model automatic cooling system cost is low, function admirable, operate steadily, safe and reliable, be widely used on pumps for hot water supply net, have good economic benefit and social benefit.
Personnel in the art should be realized that, above-described embodiment is not with this novel restriction of opposing, as long as in this novel connotation scope, any above-described embodiment technique variation, flexible program are not all exceeded protection domain of the present utility model.
