Abstract
The utility model relates to a jet type centrifugal pipeline pump assembly. Two semicircle grooves are disposed axially at the inlet of interface seat 6. A thread interface is disposed radially and connected with a conical nozzle 9 and a shrinkable connection tube 8 respectively by an outer thread at the outlet to form a jet device, which is accessed to the inlet of centrifugal pipeline pump assembly 1 by a flange of the shrinkable connection tube 8 to compose the jet centrifugal pipeline pump assembly. The outlet of pump 1 is connected with the radial thread interface of the interface seat 6, and the flange of the interface seat 6 is connected with a suction line, by an external pipeline. When pump 1 operates, partial high-pressure liquid at the outlet passes through the radial thread interface of the interface seat 6 and enters the conical nozzle 9 to form a high-speed liquid. Under the effect of atmospheric pressure, the suction line liquid passes through the two semicircle grooves at the inlet of the interface seat 6 and enters with the high-speed liquid into the pump 1 inlet connected with the shrinkable connection tube 8 to generate a certain pressure, thereby avoids cavitation of the pump 1.
Description

The utility model relates to a kind of jet-type centrifugal pipeline pump group
Background technique
Domestic centrifugal pipeline pump is widely used in petrochemical industry at present, as the flow process pump, generally employing along with underground utility, for reducing investment, the little pump house of establishing selects for use high-head pump to carry at a distance, along with the oil transportation inlet line increases, suction condition degenerates, and pump is easy to generate cavitation when work.
For improving service condition, produce cavitation when avoiding work, jet-type centrifugal pipeline pump group has been proposed.
Summary of the invention
The purpose of this utility model provides a kind of jet-type centrifugal pipeline pump group.By setting up the liquid jet device, improve the cavitation performance of pump.
The purpose of this utility model is achieved like this: interface block 6 imports axially have two semi-circular groove, threaded coupling is radially arranged, be connected with conical nozzle 9, contraction shape collecting pipe 8 respectively by going out interface external thread, form liquid jetting device, insert 1 import of centrifugal pipeline pump group by the flange that shrinks shape collecting pipe 8, form jet-type centrifugal pipeline pump group.By exterior line with pump 1 outlet(discharge) flange and interface block 6 radially screw thread link to each other, interface block 6 flanges link to each other with suction line.When pump 1 work, the exit portion highly pressurised liquid by interface block 6 radially threaded coupling enter conical nozzle 9, and formation high-speed liquid, under the barometric pressure effect, suction line liquid together enters pump 1 import that contraction shape collecting pipe 8 links to each other in company with high-speed liquid, and has produced certain pressure through axial two semi-circular groove of interface block 6 imports, thereby changed suction condition, avoided the cavitation of pump.

Fig. 1 the utility model jet-type centrifugal pipeline group
Specific embodiments
Shown in Figure 1, interface block 6 imports axially have two semi-circular groove, threaded coupling is radially arranged, be connected with conical nozzle 9, contraction shape collecting pipe 8 respectively by going out interface external thread, form liquid jetting device, insert 1 import of centrifugal pipeline pump group by the flange-interface that shrinks shape collecting pipe 8, form jet-type centrifugal pipeline pump group.When interface block 6 radially threaded coupling feed highly pressurised liquid, behind conical nozzle 9, form high-speed liquid, under the atmospheric pressure effect, suction line liquid is through interface block 6 imports two semi-circular groove, along with together entering, high-speed liquid shrinks pump 1 import that shape collecting pipe 8 links to each other, and produce certain pressure, thereby avoided cavitation.
