Abstract
The utility model discloses a novel pump seal cooling device of a centrifugal pump, which comprises a pump seal. The utility model is characterized in that a pump seal liquid circulation device which comprises a high-level slot, a heat exchanger and a connection pipe are arranged on the pump seal, the heat exchanger is a liquid cold heat exchanger based on water as a cooling dielectric, the temperature of the centrifugal pump seal liquid can be reduced in the action of the heat exchange of the heat exchanger, the connection pipe can be used from metal pipes, the heat exchange dielectric of the heat exchanger is water. The novel pump seal cooling device changes the prior used wind cooling and improves the cooling effect, thereby reaching the function of protecting the centrifugal pump seal. Thereby the maintenance cost is reduced greatly, the maintenance is simple and the investment cost is low.
Description
Technical field
The utility model relates to a kind of auxiliary device of centrifugal pump, particularly a kind of novel centrifugal pump pump machine envelope cooling device.
Background technique
At present, in China production of polyester field, use the liquid phase heating agent in a large number, this medium heat transfer ratio height, structural stability is a kind of good conduction oil.Stable as the centrifugal pump that the conveying equipment of this heating agent is selected, but its machine envelope is lubricated and external heating agent is adopted in sealing, air-cooled circulation, its cooling effect is general, thereby easily cause pump machine envelope temperature drift and the machine envelope is damaged frequently, as keeped in repair or change, about 20,000 yuan of every cover loses bigger.
Summary of the invention
The purpose of this utility model is to provide a kind of good cooling results for the deficiency that solves above-mentioned technology, makes the centrifugal pump machine seal non-damageable a kind of novel centrifugal pump pump machine envelope cooling device.
In order to achieve the above object, a kind of novel centrifugal pump pump machine envelope cooling device that the utility model is designed, comprise pump machine envelope, it is characterized in that sealing up at the pump machine and be provided with the pump machine sealing liquid circulation means of being made up of high position tank, heat exchanger and connecting tube, described heat exchanger is to be cooling medium liquid cooling heat exchanger with water.Under the heat exchange action of heat exchanger, play cooling to centrifugal pump pump machine sealing liquid, connecting tube available metal pipe constitutes, and the heat transferring medium of heat exchanger is a water, changes the original air cooling of using, and improves cooling effect, thereby reaches the effect of protection centrifugal pump machine envelope.
Find that through scrutinizing and putting into practice centrifugal pump transmits about 300 ℃ of liquid heat medium temperature, the effect of machine envelope cooling unit after exactly the heat of machine envelope being brought to pump and cools off cooling outward by sealing fluid, enters in the machine envelope by high-order circle groove again.So constantly circulation, assurance machine envelope temperature is unlikely too high, reaches the effect of sealing simultaneously.
Air cooling effect is general because the fed sheet of a media temperature up to 300 ℃, is held concurrently, and causes machine end-blocking surface temperature constantly to be assembled, and has quickened the aging of machine envelope, in case be damaged, will cause a large amount of heating agents to leak, and the machine envelope also must a complete set ofly be changed.
The utility model carries out the Forced water cooling heat exchange to sealing fluid, has improved cooling effect, has protected centrifugal pump pump machine envelope.Concrete advantage is as follows:
1. significantly reduce maintenance expenses.As the original device operation, the machine envelope life-span is about 1 year, and behind the employing new device, the machine envelope is obviously elongated service life.
2. safeguard that simply input cost is low.This device adopts maturation process, and is simple in structure, and general personnel can safeguard.
Description of drawings
Fig. 1 is the utility model example structure schematic representation;
Wherein: heat exchanger 1, high position tank 2, pump machine envelope 3, connecting tube 4.
Embodiment
The utility model will be further described in conjunction with the accompanying drawings below by embodiment.
Embodiment 1
As shown in Figure 1, a kind of novel centrifugal pump pump machine envelope cooling device that present embodiment is described, comprise pump machine envelope (3), it is characterized in that being provided with the pump machine sealing liquid circulation means of being made up of high position tank 2, heat exchanger 1 and connecting tube 4 on pump machine envelope 3, described heat exchanger 1 is to be cooling medium liquid cooling heat exchanger with water.Under the heat exchange action of heat exchanger 1, play cooling to centrifugal pump pump machine sealing liquid, connecting tube 4 available metal pipes constitute; the heat transferring medium of heat exchanger is a water; change the original air cooling of using, improve cooling effect, thereby reach the effect of protection centrifugal pump machine envelope.
