Abstract
The invention relates to a sealed inner flushing device for a double-suction axially split pump. The double-suction axially split pump comprises a pump cover and a sealed body connected with the pump cover, the sealed inner flushing device comprises a cylindrical water tank and a crescent water tank, the cylindrical water tank is arranged on the pump cover, the crescent water tank is arranged at the connecting position of the pump cover and the sealed body, and the cylindrical water tank and the crescent water tank are communicated. High-pressure water in the pump cover enters the sealed body through the cylindrical water tank and the crescent water tank, and the sealed body is sealed or flushed or cooled. Compared with the prior art, the sealed inner flushing device has the advantages of being simple in structure and good in effect.
Description
Technical field
The present invention relates to a kind of sealing flusher, especially relate to a kind of for Rinsing unit in the sealing of Double entry middle-opening pump.
Background technique
Existing Double entry middle-opening pump is sealflushed structure two kinds: a kind of is outer flushing mechanism, and this structure is to pass through externally connected pipe pass high pressure water to seal at the top of pump cover.Another kind is interior flushing mechanism, and this structure is at pump cover and seal direct casting inclined hole, high pressure water to be guided in Seal cage respectively.The sealing of outer flushing mechanism, flushing line is loaded down with trivial details and affect the compact aesthetic property of outward appearance, also often occurs seal leak phenomenon.Interior flushing mechanism is on pump cover and seal, to cast out an inclined hole, because casting inclined hole is longer, increased the difficulty of casting, and two inclined holes can not finely align, and high pressure water can not be introduced in seal completely, has a strong impact on cooling, sealing, developing result.
Summary of the invention
Object of the present invention be exactly in order to overcome the defect that above-mentioned prior art exists, provide a kind of developing result good, simple in structure for Rinsing unit in the sealing of Double entry middle-opening pump.
Object of the present invention can be achieved through the following technical solutions:
A kind of for Rinsing unit in the sealing of Double entry middle-opening pump, described Double entry middle-opening pump comprises pump cover and the seal being connected with pump cover, in described sealing, Rinsing unit comprises cylindrical tank and crescent shape tank, described cylindrical tank is located on pump cover, described crescent shape tank is located at the joint of pump cover and seal, and described cylindrical tank is connected with crescent shape tank; High pressure water in pump cover enters seal by cylindrical tank and crescent shape tank, to seal seal, flushing or cooling.
Described pump cover is provided with hyperbaric chamber, and described cylindrical tank is connected with hyperbaric chamber.
Described seal comprises Seal cage, and described crescent shape tank is connected with Seal cage.
The diameter of described cylindrical tank is 8～14mm.
The width of described crescent shape tank is 8～14mm.
Described seal is mechanical seal body or packing seal body.
Compared with prior art, the present invention is placed in the inside of pump sealflushing water channel through structural design cleverly, has removed loaded down with trivial details external pipeline, the compact overall structure of pump and attractive in appearance, not only convenient for users to use, and make to sealflush more directly effectively.
