Abstract
The utility model relates to a double ammonia feeding filter used in high speed pump, in particular to a mechanical seal washing device for high speed centrifugal ammonia pump, which solves deficiencies of current technologies and comprises a balancing valve, a switching valve, a filter shell, two tube bodies, two filter cores and two exhausting valves. The ammonia filter adopts double installation with the whole filter is composed of two tube bodies. The two filter cores are respectively fixed on the filter shell by blots. The switching valve is instated on top end of the filter shell, and the balancing valve is arranged on bottom end of the switching valve. The two exhausting valves are respectively arranged below the two tube bodies.
Description
One, technical field: the utility model relates to a kind of mechanical seal rinsing device of high speed centrifugation ammonia pump, and especially a kind of high speed pump is adorned the ammonia filter with duplex.
Two, background technique: the high speed centrifugation ammonia pump is a large chemical fertilizer urea device equipment commonly used, its total three seals, the sealing of first road is general to be adopted from flushing, promptly use liquefied ammonia as washing solution, because flushing ammonia is dirtier in the actual production, and original filtrating equipment seal form is bad, often make flushing ammonia walk short circuit, cause mechanical seal often to leak, have a strong impact on the stable operation of this pump, can cause when serious that device stops.
Three, summary of the invention: the purpose of this utility model provides a kind of high speed pump and adorns the ammonia filter with duplex, it has solved the deficiency of present technology, it is to be formed by connecting by equilibrium valve, switching valve, filter housings, cylindrical shell, filter core, escape cock, this kind ammonia filter adopts duplex dress form, whole filter is made up of two cylindrical shells, two filter cores are fixed by bolts to respectively on the filter housings, and switching valve is installed in the upper end of filter housings, and equilibrium valve is installed in the top of switching valve; Two escape cocks be installed in respectively two cylindrical shells below.
The beneficial effects of the utility model are: (1) changes traditional filter core into an end feed liquor by the two ends feed liquor, mounting end adopts and is threaded simultaneously, with the sealing of O shape ring, has stopped flushing ammonia and has walked short circuit, avoid the impurity in the liquid to enter the mechanical seal chamber, protected mechanical seal; (2) two filter cores one are opened one and are equipped with, and have accomplished and can on-line cleaning switch filter core. (3) owing to can have certain first ammonium liquid in the liquefied ammonia in the ordinary production, the used unit of this filter adopts special-purpose resistant material, and sealed member also adopts resistant material, prolongs the working life of filter.
Four, description of drawings: Fig. 1 is a kind of high speed pump with duplex dress ammonia structure of filter schematic representation, among the figure 1, equilibrium valve 2, switching valve 3, filter housings 4, cylindrical shell 5, filter core 6, escape cock
Five, embodiment: in Fig. 1, this kind ammonia filter adopts duplex dress form, two cylindrical shells 4 are fixed on the filter housings 3, two filter cores 5 are fixed by bolts to respectively on the filter housings 3, switching valve 2 is installed in the upper end of filter housings 3, and equilibrium valve 1 is installed in the top of switching valve 2; Two escape cocks 6 be installed in respectively two cylindrical shells 4 below.
Claims (1)
