Pitot tube pump is a high-speed centrifugal pump, is made up of driving machine, speed increaser and pump three parts.The horizontal type structure pitot tube pump of ROTOJET company for example.The impeller of high-speed centrifugal pump is a full-open type, and blade is the prismatic blade of radiation, and two kinds of structural shapes of impeller of general impeller and band inducer are arranged; The impeller cantilever is contained on the pump shaft, pump shaft and speed increaser high speed shaft direct connection; Pumping chamber in the pump housing is an annular, and the space is very little, and at 1～2 conic diffuse of pumping chamber arranged around, the anemostat import is provided with nozzle 10 (as illustrated in fig. 1 and 2), and the size of nozzle 10 has considerable influence to pump performance.This pump lift is big, and flow is less, is used for carrying containing solia particle and full-bodied liquid, and the accessory required precision is high, and is difficult in the manufacturing.
Pump chamber inner nozzle 10 can rotate when machine sealed outside changing; Break away from origin-location (nozzle 10 is vertically to install); The bolt eye 11 of fixed nozzle 10 is what be uniformly distributed with, but angle is not positive-angle (in order to guarantee the fixing of angle), and purpose is exactly guarantee pump chamber inner nozzle 10 angles certain.So nozzle 10 fixedly is the most time-consuming one procedure when maintenance.
Therefore, for the problems referred to above and the defective that solves existence, a kind of pitot tube pump special tool for service need be provided, it can retaining element and regulates part position, thereby reduces maintenance mans' labour intensity, reduces the maintenance risk, promotes production efficiency.
The utility model content
The purpose of the utility model is to have overcome above-mentioned shortcoming of the prior art; A kind of pitot tube pump special tool for service is provided, and the design of this pitot tube pump special tool for service is ingenious, can retaining element and regulate part position; Thereby reduce maintenance mans' labour intensity; Reduce the maintenance risk, promote production efficiency, be suitable for large-scale promotion application.
To achieve these goals; The pitot tube pump special tool for service of the utility model; Be characterized in, comprise threaded rod, locking member, expansion tube and expansion-head, said expansion-head is installed in an end of said threaded rod; Said locking member is threadably engaged on the said threaded rod, and said expansion tube is set on the said threaded rod and between said expansion-head and said locking member.
Preferably, said expansion tube offers some roads expansion hatch along its length.
More preferably, said expansion hatch and said expansion-head are contiguous is provided with.
More preferably, the number of said expansion hatch is 4, and the parallel interval setting.
Preferably, said pitot tube pump special tool for service also comprises pad, and said pad is set on the said threaded rod and between said expansion tube and said locking member.
Preferably, said locking member is a nut.
The beneficial effect of the utility model specifically is: the pitot tube pump special tool for service of the utility model comprises threaded rod, locking member, expansion tube and expansion-head, and said expansion-head is installed in an end of said threaded rod, and said locking member is threadably engaged on the said threaded rod; Said expansion tube is set on the said threaded rod and between said expansion-head and said locking member, takes over thereby insert nozzle, and behind the locking member of screwing; Expansion-head and expansion tube are expanded, utilize the frictional force between the adapter of expansion-head and expansion tube and nozzle to fix nozzle, then adjusting angle; To good bolt eye, install the locking member that comes loose behind the bolt, cancel expansive force; Take out specific purpose tool, design ingenious, can retaining element and regulate part position; Thereby reduce maintenance mans' labour intensity; Reduce the maintenance risk, promote production efficiency, be suitable for large-scale promotion application.
