Description
Technical field:
The present invention relates to middle-opening pump technical fields, and in particular to external cooling is configured when a kind of novel middle-opening pump free-runing operation
The pipeline structure that water is cooled down and protected to mechanical seal and casing ring.
Background technique:
General middle-opening pump passes through 11 flushing schemes at runtime and realizes to machine sealing flushing and cooling.When pump downtime compared with
Long, the free-runing operation that need to be switched at regular intervals is primary, does not run to prevent the long period and causes the axis in rotor part can be different
Degree is bent downwardly, and will cause very big influence to booting next time.When pump is switched on free-runing operation, rotary part and stationary parts
The core component (such as casing ring, machine envelope, axis) in water pump can be caused certain because of continual dry friction and wear
The damage of degree will affect booting operation next time and service life of water pump.
Summary of the invention
In view of the deficiencies of the prior art, the present invention provides configure external cooling water when a kind of novel middle-opening pump free-runing operation
The pipeline structure that mechanical seal and casing ring are cooled down and protected makes water pump reduce rotary part in free-runing operation
With the abrasion of stationary parts, so that the service life of water pump will greatly prolong.
To achieve the above object, the present invention is realized by following concrete scheme:
Cooling water carries out the pipeline of cooling protection to mechanical seal and casing ring, comprising: and one, machine sealing flushing component:
Machine sealed cover (1) and copper tube one (4), which is characterized in that machine sealed cover (1) and copper tube one (4) are first by reducing socket
(2) and pipe nut one (3) connection, copper tube one (4) other end use pipe nut two (5), pipe fitting (6) He Zhong great reducer tee
(7) connect, in big reducer tee (7) other end connected by nipple one (8), restricting orifice (9) and reducing cross (20)；
Two, sealing ring flushing component: pass through pipe reducer three (16), pipe nut four (15) between pump cover (17) and copper tube two (14)
Connection, copper tube two (14) other end pass through pipe nut three (13), pipe reducer two (12) and ball valve one using being threadedly coupled
(11) it connects, one other end of ball valve passes through big reducer tee (7) connection, structure in nipple two (10) and machine sealing flushing component
Cause primary Ioops；Three, exhaust circuit component: it is connected through a screw thread at the top of pump cover (17), passes sequentially through nipple three (18), ball valve
Reducing cross (21) connection in two (19), nipple four (20) and machine sealing flushing component, reducing cross (21) upper end passes through interior
Connector three (18) and ball valve three (22) connection.
Further technology: the accessory in the pipeline is using being threadedly coupled, and the cooperation of internal and external threads is gap-matched, energy
Expire the intensity requirement of bolt matable assembly, enough so as to reduce cost.
Further technology: the effect of the restricting orifice (9) is that aperture becomes smaller in the appropriate place of pipeline, when liquid passes through
Necking is crossed, a fluid stream can attenuate or shrink, to prevent cavitation phenomenons generation.
Further technology: the angle between the pump cover (17) and copper tube two (14) is 45 °, and the purpose is to make in pipeline
Liquid it is wider to the flushing areal extent of water pump gland ring.
Further technology: the interface connecting with outer water receiving in the pipeline only has at one, by connecting with ball valve three (22)
It connects, the purpose is to reduce the external water source contact of pump use site.
The utility model has the advantages that
Through the invention due to using the above structure, having structurally reasonable, guarantee water pump rotary part in free-runing operation
Can be because of continual dry friction and wear with stationary parts, it can be to core component (such as casing ring, the machine envelope, axis in water pump
Deng) a degree of damage is caused, it will affect booting operation next time and service life of water pump.Because pipe line parts thus are few and all
For standard component production it is simple, run smoothly, it is easy to use, easy for installation, component and casing ring good cooling results are sealed to machine
The advantages that, also allow its manufacturing cost to be easy that client is allowed to receive.
