Abstract
The utility model relates to a single box with a separated type liquid storage and air-liquid separated chamber 20, an bottom inlet is arranged at an outlet of an easy-disassemble type centrifugal pipeline pump; the liquid storage and air-liquid separated chamber 20 are communicated with an inlet part of the impeller 16 in a pump body 18 through an external refluxing pipe 19; a stop valve is arranged in the external refluxing pipe 19; the gap between a impeller 16 and a tongue of a pump body 18 is reduced to 0.5 to 1 mm, thereby the separated type easy-disassemble self-sucking centrifugal pipeline pump formed. Due to adoption of the internal mixing type self-sucking form, the self-sucking capacity is greatly improved; and the reflux limitation method can be adopted during normal infusion so as to reduce cubage loss and improve pump efficiency; simultaneously manufacturing and processing conditions are improved, and practicality is increased.
Description
Affiliated technical field
The utility model relates to a kind of separately placed type and just tears self-priming centrifugal pipeline pump open.
Background technique
Existing detachable type centrifugal pipeline pump has two kinds of structural types: one, and detachable type centrifugal pipeline pump does not have self-absorption function; They are two years old, the detachable type self-priming centrifugal pipeline pump that adopts liquid storage, gas-liquid separation chamber and motor cabinet to be integrated, complex structure, process very difficult, and because of adopting external mixture type self-priming form, suction capacity a little less than, when working simultaneously, waterpower and volumetric loss are bigger, cause the efficient of pump low, thereby have limited it and used and development.
Summary of the invention
The purpose of this utility model provides a kind of separately placed type and just tears self-priming centrifugal pipeline pump open, is used to solve carry chemical medium because the gas that evaporates, vaporizes and produce improves suction capacity, and improves manufacturing, processing conditions.
The purpose of this utility model is achieved like this: the single casing that adopts separately placed type liquid storage, gas-liquid separation chamber 20, bottom inlet is contained in detachable type centrifugal pipeline pump discharge, with external reflux pipeline 19 liquid storage, gas-liquid separation chamber 20 are communicated with impeller 16 inlet part in the pump housing 18, adorn stop valve on the external reflux pipeline 19, reduce impeller 16 and arrive 0.5-1mm, just tear self-priming centrifugal pipeline pump open thereby constitute separately placed type with the pump housing 18 cut water gaps.Storage stream, gas-liquid separation chamber 20 are square box, and casing outlet top is gas-liquid separation chamber, and the bottom is a liquid storage room, and external reflux pipeline 1`9 is communicated with the liquid storage room bottom with impeller 16 import positions in the pump housing 18.When the self-priming process, the gas-liquid mixture that inlet ductwork air and liquid storage are discharged after quick runner 16 mixes, separate in liquid storage, gas-liquid separation chamber 20, gas is discharged through liquid storage, gas-liquid separation chamber's 20 outlets, and liquid is deposited in liquid storage, gas-liquid separation chamber 20 bottoms, is back to impeller 16 imports through external reflux pipeline 19, mix through quick runner 16 with the inlet ductwork air once more, this process circulation is carried out, and until the inlet ductwork air is drained, finishes the self-priming process.Because withdrawing fluid is directly introduced impeller 16 imports in the pump housing 18, has formed internal-mixing self-priming form, has improved suction capacity greatly.Simultaneously during normal infusion, can be by external reflux pipeline 19 limit return flow.During each termination of pumping, can stay the required liquid of the next self-priming of enough confessions in liquid storage, the gas-liquid separation chamber 20.
Adopt the utility model structure, enlarged the using scope of detachable type self-priming centrifugal pipeline pump, and compare with similar detachable type self-priming centrifugal pipeline pump, simple in structure, self-priming performance good, volumetric loss is little, the efficient height of pump.
Description of drawings:
Fig. 1, separately placed type of the present utility model are just torn self-priming centrifugal pipeline pump structure sketch open;
Fig. 2, separately placed type liquid storage of the present utility model, gas-liquid separation chamber's structure diagram.
Embodiment
Shown in Figure 1, liquid storage, gas-liquid separation chamber 20 are installed in and just tear self-priming centrifugal pipeline pump discharge open, by external reflux pipeline 19 liquid storage, gas-liquid separation chamber 20 are communicated with impeller 16 import positions in the pump housing 18.The installation of pump: bearing 7 first hot jackets in the bearing support 13 of packing into, are adorned sealing seat 11, mechanical seal 12, impeller 16, locking impeller nut 15 then on pump shaft 8, install bearing (ball) cover 6, are assembled into the bearing support assembly.Motor cabinet 2 is contained on the pump housing 18, loads onto the bearing support assembly, adorn 2 half snap rings 3 on 1 in dress back-up ring 5, the motor on the pump shaft 8, pump shaft 8 is connected with motor, be assembled into separately placed type and just tear self-priming centrifugal pipeline pump open with two half-couplings 4.
Shown in Figure 2, provided the structure of liquid storage, gas-liquid separation chamber 20.
