Abstract
The utility model discloses a desulphurization pump with a freezing and congealing resisting and liquid discharging device. The desulphurization pump with the freezing and congealing resisting and liquid discharging device comprises a front pump cover, an impeller, a pump body, a rear protection plate, a rear pump cover, a mechanical seal, a shaft sleeve and a bracket component, wherein a liquid discharging hole is formed in the lower end of the pump body and is connected with a liquid discharging pipe provided with a sluice valve. Because the discharging hole is formed in the pump body of the desulphurization pump, the sluice valve is adjusted to flexibly control discharging of liquid in a pump cavity and prevent the liquid from being deposited in the pump cavity and damaging the pump body and the mechanical seal, the pump body and the mechanical seal are protected, and the service life of the pump is prolonged.
Description
Technical field
The utility model relates to a kind of desulfur pump with antifreeze anti-condensation pumping equipment.
Background technique
The absorption tower recycle pump is the large-scale key equipment in flue gas desulfur device, and its reliability and working life are had high requirements.Tradition desulfur pump major defect is to get rid of in time the corrosive liquids of deposition in pump chamber, thereby the pump housing and mechanical seal are caused damage.When system is out of service, the liquid in the desulfur pump pump chamber can not thoroughly be discharged, and makes liquid in pump chamber deposit in a large number, causes the corrosion of the pump housing; Especially in northerly winter, the system easier temperature influence of rear liquid out of service and freezing, cause damage to the pump housing and mechanical seal.
Summary of the invention
The utility model is for above-mentioned problems of the prior art, provides that a kind of efficiency is high, simple in structure, low cost of manufacture, the desulfur pump with antifreeze anti-condensation pumping equipment easy to maintenance.
The technical solution adopted in the utility model is as follows: a kind of desulfur pump with antifreeze anti-condensation pumping equipment, comprise front pump cover, impeller, the pump housing, rear backplate, rear pump cover, mechanical seal, axle sleeve, carriage member, pump housing lower end has outage, outage connected drainage pipe, liquid-discharging tube is provided with gate valve.
Preferably, embedded part is housed in outage, embedded part is provided with the Internal Pipe Thread coordinated with liquid-discharging tube.
Preferably, be provided with the polytetrafluoroethylraw raw material band for sealing between liquid-discharging tube and embedded part.
Adopt the desulfur pump with antifreeze anti-condensation pumping equipment of the technical program to compare with conventional art, its advantage is: have outage on the pump housing, the thorough discharge of liquid in pump chamber when the system of being convenient to is out of service, control flexibly discharge liquid by regulation gate valve, prevent the deposition of liquid in pump chamber, the pump housing and mechanical seal are worked the mischief, the protection pump housing and mechanical seal, the working life of prolongation pump; Especially northerly winter, can prevent locking system rear liquid out of service freeze the pump housing is caused unfavorable; Do embedded part on the pump housing, attack Internal Pipe Thread, for connecting the pump housing and liquid-discharging tube, extend the working life of pump; Helical thread portion at liquid-discharging tube is wrapped with and can reaches good sealing by etch-proof polytetrafluoroethylraw raw material band.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
As shown in Figure 1, desulfur pump with antifreeze anti-condensation pumping equipment of the present utility model, comprise front pump cover 1, impeller 2, the pump housing 3, rear backplate 4, rear pump cover 5, mechanical seal 6, axle sleeve 7, carriage member 8, the pump housing 3 lower ends have outage 9, on the pump housing 3, tapping is done embedded part, attacks Internal Pipe Thread, by screw thread, with liquid-discharging tube 10, is connected, helical thread portion at liquid-discharging tube 10 is wrapped with and can be sealed by etch-proof polytetrafluoroethylraw raw material band, and liquid-discharging tube is provided with gate valve 11.Pump is shut down the not used time, by opening gate valve 11, makes liquid pass through liquid-discharging tube 10 discharges; When pump normally moves, closing gate valve 11.
Personnel in the art should be realized that, above-described embodiment is not with this novel restriction of opposing, as long as at this in novel connotation scope, any above-described embodiment technique variation, flexible program are not all exceeded to protection domain of the present utility model.
