Abstract
The utility model relates to a two-stage two-pipe inlet double-suction pump casing in symmetrical distribution at a central line. The casing includes water absorption openings and a water outlet, and is characterized in that a secondary discharge chamber is arranged at the center of the casing and communicated with the pump water outlet, two sides of the secondary discharge chamber are respectively connected with a secondary suction chamber which is respectively connected with a primary discharge chamber on the outer lateral face, the primary discharge chambers are respectively connected with primary suction chambers on the outer lateral face, and the water absorption openings are respectively arranged on the primary suction chambers. The pump casing changes one original water inlet of an original double-suction pump with one inlet and one outlet into two symmetrical water inlets in design, and absorbs water from the respective inlets on two sides of the pump, and the symmetrically distributed casing structure can automatically balance radial force, and is easy in production and processing.
Description
Technical field
The utility model relates to a kind of pump case, the two-tube import double suction pump of particularly a kind of two-stage housing.
Background technique
Existing two-stage double suction pump housing is the single tube import, connects chopped-off head suction chamber, chopped-off head delivery chamber, secondary suction chamber, secondary delivery chamber successively by the water sucking mouth, is communicated with at last and pumps the mouth of a river.Housing is asymmetrical structure.Radial force imbalance when water pump operation, what generating pump moved easily rocks, and processing is difficult for.
Summary of the invention
The purpose of this utility model is to solve existing the problems referred to above of two-stage double suction pump housing in the prior art, and the two-tube import double suction pump of a kind of two-stage housing is provided.The two-tube import double suction pump of the utility model design two-stage housing, it is characterized in that: housing is symmetrically distributed along center line.It is characterized in that: comprise water sucking mouth, water outlet, it is characterized in that: the centre of housing is secondary delivery chamber, the mouth of a river is pumped in secondary delivery chamber connection, both sides at secondary delivery chamber connect secondary suction chamber respectively, secondary suction chamber connects the chopped-off head delivery chamber of outer side surface separately, the chopped-off head delivery chamber connects the chopped-off head suction chamber of outer side surface again separately, on the chopped-off head suction chamber water sucking mouth is arranged.The utility model has changed the structure of two-stage double suction pump one-in-and-one-out in the past.And an original water intake is designed to the water intake of two symmetries, separately the import suction from the pump both sides simultaneously, but the shell construction autobalance radial force of this symmetrical distribution is easy to production and processing simultaneously.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Below in conjunction with accompanying drawing and example the utility model is elaborated.
Embodiment
Figure middle shell 1 is symmetrically distributed along center line.It is characterized in that: comprise water sucking mouth 2, water outlet 3, it is characterized in that: the centre of housing 1 is secondary delivery chamber 4, the mouth of a river 3 is pumped in secondary delivery chamber 4 connections, connect secondary suction chamber 5 respectively on the both sides of secondary delivery chamber 4, secondary suction chamber 5 connects the chopped-off head delivery chamber 6 of outer side surface separately, chopped-off head delivery chamber 6 connects the chopped-off head suction chamber 7 of outer side surface again separately, and water sucking mouth 2 is arranged on the chopped-off head suction chamber 7.
Liquid is entered by water sucking mouth 2, is divided into two strands and enters chopped-off head delivery chamber 6 by both sides chopped-off head suction chamber 7, enters secondary suction chamber 5 through the transition runner again, and the liquid that enters the secondary suction chamber 5 in both sides converges together, enters secondary delivery chamber 4, flows out by pumping the mouth of a river 3 again.
Claims (2)
1. the two-tube import double suction pump of two-stage housing, it is characterized in that: housing is symmetrically distributed along center line.
2. by the two-tube import double suction pump of the described two-stage of claim 1 housing, it is characterized in that: comprise water sucking mouth, water outlet, it is characterized in that: the centre of housing is secondary delivery chamber, the mouth of a river is pumped in secondary delivery chamber connection, both sides at secondary delivery chamber connect secondary suction chamber respectively, secondary suction chamber connects the chopped-off head delivery chamber of outer side surface separately, and the chopped-off head delivery chamber connects the chopped-off head suction chamber of outer side surface again separately, on the chopped-off head suction chamber water sucking mouth is arranged.
