Description
The utility model patent belongs to field of mechanical technique, relates to a kind of two-stage vertical self-priming pipeline mounted pump.
Existing vertical self-priming pipeline mounted pump since have simple in structure, easy to operate, floor space is little, self-priming performance is good and characteristics such as reliable operation, thereby uses extremely wide in all trades and professions.Yet, take a broad view of at present that all vertical self-priming pipeline mounted pumps are single-stage, its work lift is subjected to the restriction of the peripheral velocity of pump structure, pump and impeller material etc., can not infinitely increase.To up to now, such lift of pump does not all have and surpasses 125 meter water columns.So, when occasion more high-lift at needs and the farther distance transfusion of chance operating mode, such pump must adopt the series connection of pumps more than two or two to finish the usage requirement of operating mode, but this certainly will increase expense investment of equipment, and move also uneconomically, system is also comparatively complicated.In addition, in some mobile facility (for example boats and ships naval vessels and motor vehicle) space-constrained occasion, because installation conditions is limited, such pump also often can not be finished high-lift transfusion, also often can not adopt the form of two series connections of pumps to satisfy usage requirement.This shows that though vertical single-stage self-priming pipeline mounted pump has bigger advantage, its using scope has been subjected to great constraint in some occasion.For this reason, invent and develop a kind of compact structure, the multistage vertical self-priming pipeline mounted pump that volume is little solves the problem of the high-lift operating mode transfusion of vertical self-priming pipeline mounted pump difficulty and the application area of high-lift transfusion engineering system of simplification and expansion vertical self-priming pipeline mounted pump is necessary.
The purpose of the utility model patent be exactly propose a kind of improved, utilize the internal structure of pump own to finish self-absorption function and can carry the high-lift two-stage vertical self-priming pipeline mounted pump of liquid, to overcome the deficiency that original vertical self-priming pipeline mounted pump exists, satisfy the usage requirement of actual conditions.
The task of the utility model patent is achieved through the following technical solutions.
The basic structure form of the utility model patent is that pump is vertical arrangement, and motor is positioned on the pump box body, and the pump box body is positioned on the pump housing, and pump inlet and pump discharge are located at pump box body both sides respectively, and on same horizontal line.Wherein by the housing main body that has been combined to form pump of pump box body and the pump housing and secondary feed liquor device.In the housing main body of this structure, have two corresponding volutes, two corresponding cut waters, a diffusing pipe of pumping chamber, a liquid storage room, a gas-liquid separation chamber, a return port, a secondary volute passage, a suction chamber and an exhaust port.The inside and outside component such as coupling, vacuum gauge, pump inlet seat, pump shaft, mechanical sealing base, mechanical seal, bearing, centrifugal impeller, middle pump cover, pump discharge seat and pressure gauge that are equipped with at housing main body.The lower horizontal middle part that is placed in the pump housing on two corresponding volutes of above-mentioned feature.Two corresponding cut water starting points stagger respectively in two volutes relatively.The pumping chamber diffusion levels is laid and is connected with the secondary volute outlet of the pump housing.Liquid storage room is formed and is positioned at the below of gas-liquid separation chamber by the pump housing and the cavity volume below the pump box body suction chamber.Gas-liquid separation chamber is arranged in the cavity on the pump box body top on the liquid storage room.Return port is arranged on the pump box body and the pump housing and with liquid storage room and secondary volute and gangs up, and the supply opening place of return port is arranged in the liquid storage room liquid level of pump box body, the liquid outlet place be positioned at the secondary volute IV of the pump housing '-VI ' cross section near.One secondary volute passage is communicated with the outlet of one-level volute with the import of secondary centrifugal impeller.Suction chamber is positioned at the liquid storage room top of pump box body and links to each other with the pump inlet seat, and the liquid storage room and the gas-liquid separation chamber of suction chamber and pump box body are isolated.Exhaust port is positioned at the liquid storage room top of pump box body and links to each other with the pump discharge seat, and the gas-liquid separation chamber of exhaust port and pump box body is same cavity.Two centrifugal impellers are contained in two corresponding volutes of the same pump housing with the pump shaft cooperation, and pump cover separated it in the middle of the centre was provided with, and two centrifugal impellers are back-to-back arrangements up and down, and the secondary centrifugal impeller is positioned on the first-stage centrifugal impeller.
Secondary volute in the device is positioned on the one-level volute; Secondary feed liquor device is positioned on the secondary centrifugal impeller.
Pump box body in the device is provided with a vacuum gauge and a pressure gauge, and wherein vacuum gauge is arranged on the suction chamber top, and pressure gauge is arranged on the exhaust port top.
The working procedure of the utility model Patent equipment is as follows:
Because importing and exporting, pump all has certain height, so remaining certain amount of fluid in the liquid storage room of pump at ordinary times.After the normal startup of motor drives pump, two centrifugal impeller high speed rotating, under action of centrifugal force, the first-stage centrifugal impeller sucks liquid in suction chamber and the intake line and air together, in the first-stage centrifugal impeller, mixed fully, and gas-liquid mixture being transported to the secondary centrifugal impeller by a secondary volute passage, the secondary centrifugal impeller is transported to gas-liquid mixture in the gas-liquid separation chamber of pump box body by the pumping chamber diffusing tube again.Because the effect of impeller and cut water, so lighter gas is separated from gas-liquid mixture, overflow by pump discharge, and heavier liquid turns back in the secondary volute of the pump housing by return port, again mix with the gas in the centrifugal impeller, continue to participate in the centrifugation of exhaust process ...The motion that goes round and begins again according to this, the gas that reaches in the intake line in pump is all drained, and pump has just been finished the self-priming process.Then, pump just can be put into normal transfusion working state automatically.
This two-stage vertical self-priming pipeline mounted pump utility model patent has the following characteristics:
1, utilizes the internal structure of pump own and need not outside any additional aids and can finish self-absorption function, be both the function that also has transfusion.
2, two centrifugal impellers participate in the gas-liquid separation effect, have shortened the process of gas-liquid separation, have improved the self-priming effect of pump.
3, break through the boundary that present vertical single-stage self-priming pipeline mounted pump dehvery lift can not be higher, solved the difficult problem of the high-lift transfusion of vertical self-priming pipeline mounted pump, enlarged the application area of vertical self-priming pipeline mounted pump.
4, novel, simple and reasonable, volume is little, and is easy to maintenance.
5, kept the due characteristics of former centrifugal pump, had easy to operately, operated steadily, used the zone wide, function admirable, advantage such as functional reliability is good.
