The material of the overflow parts adopts the stainless steel, the copper, or the engineering plastic. A liquid inlet chamber, an impeller, a liquid and air separation chamber, and a diffusion tube are welded into the new process through the sheet punching. The utility model has the advantages of light weight, low cost, high efficiency, corrosion resistance, and self-absorption. Besides, the utility model can be used for the food industry, the beverage industry, the brewing industry, the medicine industry, the health industry, the chemical industry, the electron industry, etc., to convey the water, the oil, and the corrosive liquids, such as the acid, the alkali, the salt, etc., which have higher temperature and higher viscidity or contain the suspended particles.

Description

Self-priming corrosion-proof shunt pump

The utility model belongs to liquid capacity-changing mechanical: the pump class.

The centrifugal pump that prior art provided can not carry the liquid that has higher temperature, viscosity or contain suspended particulate, and partial emission pump does not possess self-priming performance.

Task of the present utility model provides a kind of self-priming anticorrosion partial emission pump, can self-priming and can transporting water, oil product and higher temperature, viscosity or contain the liquid such as acid, alkali, salt of suspended particulate.

Technical characterstic of the present utility model: the characteristics that structurally adopt horizontal partial emission pump and single-stage internal-mixing self-priming pump.Main of pump adopts the it by punch and weld new process, replaces traditional casting technique, makes that pump is in light weight, cost is low, energy self-priming, corrosion-resistant.

Description of drawings: accompanying drawing is self-priming anticorrosion partial emission pump structural drawing, is a kind of embodiment of the present utility model.Among the figure, 1 intake chamber, 2 runner bodies, 3 impellers, 4 diffusing tubes, 5 liquid inlet pipes, 6 liquid gas separation chambers, 7 drain pipes, 8 envelope chambers, 9 pump shafts, 10 carriages, 11 blocking solution valves, 12 pump covers, 13 seal rings.

Embodiment's accompanying drawings of the present utility model is as follows:

Make driving source by motor, pump and motor are installed on the pump seat, motor shaft links to each other with pump shaft 9 by shaft coupling, and the blade of impeller 3 is the open type prismatic blade, uses the plate stamping moulding, and making the outlet laying angle is that 90 degree are welded on the impeller body.Runner body 2 inside are a ring runner, the outside is the cylndrical surface, its geometrical shape is made of cylndrical surface and plane, manufacturing easily, intake chamber 1, diffusing tube 4, liquid gas separation chamber 6 all are welded into an integral body with the plate stamping welding fabrication by shown position and runner body 2, are seen in the face of intake chamber's direction outward by motor, at runner body 2 ring runners left side tangent position welding diffusing tube 4, at its symmetrical sidetracking hole for back flow is arranged, link up liquid gas separation chamber and ring runner.Liquid filling hole is offered in the extreme higher position of liquid gas separation chamber 6, the extreme lower position of intake chamber 1 is offered taphole, this two hole seals with plug, is respectively equipped with liquid inlet pipe 5 and drain pipe 7 on the top of intake chamber 1 and liquid gas separation chamber 6, at the internal orifice place of liquid inlet pipe 5 installing blocking solution valve 11.With bearing and pump shaft 9 carriage 10 of packing into, load onto the sealing material of packing in pump cover 12, the axle envelope chamber 8 in turn from pump shaft 9 left ends, refill impeller 3 usefulness nuts and fix.At last seal ring 13 runner bodies 2 are loaded onto, runner body 2, seal ring 13 pump covers 12 are fastened on the carriage 10 with bolt.Impeller 3 and runner body 2 are for the inclined-plane cooperates, and its gap can be adjusted by the thickness of plus-minus seal ring 13, and reasonably gap size is between 0.3～3mm.The main parts size of pump can be with general pump made, but the material of its flow passage components intake chamber 1, liquid inlet pipe 5, runner body 2, diffusing tube 4, liquid gas separation chamber 6, drain pipe 7, impeller 3, pump shaft 9, pump cover 12 can be used stainless steel, copper or engineering plastics.Can install in the axle envelope chamber 8 tool sealing or teflon, flexible graphite stuffing filler seals.

This self-priming anticorrosion partial emission pump working principle: fill it up with startup water by the liquid filling hole in the liquid gas separation chamber 6 before the pump startup, seal with plug, this moment, blocking solution valve 11 sealed liquid inlet pipe 5 internal orifices, starting electrical machinery pump shaft 9 impeller 3 high speed rotating, make and form the foam-like fluid gas mixture in the blade wheel chamber, and be thrown to the ring runner of runner body 2 with high speed, enter liquid gas separation chamber 6 along diffusing tube 4, because specific gravity of gas is little, flowing fluid ratio is great, the foam-like fluid gas mixture separates at this, the gas come-up, escaping into drain pipe 7 discharges, liquid flows back to runner body 2 through hole for back flow, blocking solution valve 11 is opened in this process, air in the liquid inlet pipe 5 flows to the rotating center low pressure area of impeller 3 through intake chamber 1, the liquid that flows back to hole for back flow forms liquid vapour mixture again, enter liquid gas separation chamber through diffusing tube 4, isolated gas is discharged by drain pipe 7, liquid flows back to the runner body again, through circulation many times, gas in the liquid inlet pipe 5 is pumped, form relative vacuum, the liquid of being pumped enters the liquid inlet pipe 5 of certain vacuum degree, through intake chamber 1 automatically from liquid storage tank under the atmospheric pressure effect, runner body 2, be subjected to the impeller action of centrifugal force to enter diffusing tube 4 liquid gas separation chambers 6 by drain pipe 7 outputs, pump begins proper functioning.Blocking solution valve 11 is in pump under the liquid gravity effect after the termination of pumping, and automatic airtight liquid inlet pipe 5 makes and keeps full liquid status in the pump, so need not to add diversion for the second time during turn on pump again.As for a long time need not or the severe winter bad pump housing that rises that prevents to freeze, the taphole plug below the intake chamber 1 can be screwed off, the liquid in the pump is put only, turn round plug then so that deposit or reuse.

This self-priming anticorrosion partial emission pump had both had the characteristics that general self priming centrifugal pump can self-priming, possessed general partial emission pump again and can delivery temperature reaches 120 ℃, viscosity less than 50PaS or contain diameter and mix medium mutually less than the solid-liquid of 1.5mm suspended particulate shape.Can be widely used in food, beverage, brewage, industry such as medicine, health, chemical industry electronics.
