Description
Technical field
The present invention relates to the anti-pulser of a kind of wet-spraying machine, particularly relate to the anti-pulser of a kind of Double-plunger wet-spraying machine.
Background technology
The application of Wet Shotcrete Technology overcomes high, the low-quality shortcoming of dry shotcreting dust.In wet shotcreting system, wet-spraying machine delivery pump is as the core of induction system, and its transportation performance has material impact to whole wet shot system.Delivery pump conventional is at present duplex plunger pump, and the pumping cylinder placed side by side by two forms.When pumping of concrete flows into a pumping cylinder, concrete materials is extruded from another pumping cylinder by powerful hydraulic power, conveyance conduit is flowed into by S valve, S valve is that employing two hydraulic plunger tilt cylinders make it switch between two pumping cylinders, has that operating pressure is high, feed flow is large, durable a, advantage such as operation maintenance is simple and fed distance is far away firm in structure.
But, in actual applications, because the S valve of Double-plunger wet-spraying machine switches life period interval between two pumping cylinders, reduce every pumping pressure here and close to zero, cause the discontinuous conveying of material, in course of injection, occur pulse phenomenon, the material of ejection is intermittent, and along with very large noise, not only affect the quality of sprayed mortar, and certain influence is caused to the health of staff.Therefore, need the anti-pulser of a kind of Double-plunger wet-spraying machine, realize the steady and continuous operation of spray operation.
Summary of the invention
The object of the invention is, the anti-pulser of Double-plunger wet-spraying machine that a kind of structure is simple, reliable, can realize material continus convergence is provided.
The technical scheme that the present invention is adopted for achieving the above object is, the anti-pulser of a kind of Double-plunger wet-spraying machine, is arranged between wet-spraying machine and conveyance conduit, and it comprises all flanged (FLGD) tube connector in two ends, cushion dashpot, top cover, containment vessel, spring and piston rod.
Described tube connector, along offering a mouth of pipe perpendicular to tube connector tube wall orientation, the described mouth of pipe welds cushion dashpot, and described spout diameter equals described cushion dashpot cylinder diameter; One end of tube connector is connected with wet-spraying machine, and the other end is connected with conveyance conduit.
The top of described cushion dashpot cylinder body is flange face, described flange face is provided with top cover, described top cover is provided with containment vessel, and described top cover, described containment vessel and described flange face are bolted to connection; Piston rod and spring is provided with in cushion dashpot cylinder body.
Be provided with a through hole in the middle of described top cover, through-hole diameter is greater than the diameter of piston rod, and piston rod can slide up and down through through hole.
Described spring upper end withstands top cover, and piston is withstood in lower end.
Described piston rod upper end is through the through hole of top cover, and in " T " font, be hung on top cover, fall under preventing piston, piston-rod lower end connects a piston, and the soffit of piston flushes with the inner surface of tube connector.
The described anti-pulser of a kind of Double-plunger wet-spraying machine, the spring pressure value selected should meet following requirement, and when the soffit of piston flushes with the inner surface of tube connector, the pressure of spring is the half of the specified pumping pressure peak value of wet-spraying machine; When containment vessel is withstood in the upper end of piston rod, the pressure of spring is the peak value of the specified pumping pressure of wet-spraying machine.
The technique effect that technique scheme is directly brought is, Double-plunger wet-spraying machine anti-pulser structure is simple, reliable, can realize the conveying of material continuity, prevent pulse phenomenon.
Its anti-pulsed operation principle is: when Double-plunger wet-spraying machine pumping pressure is higher than a half of specified pumping pressure peak value, because spring pressure value is less than pumping pressure, part concrete materials heads on piston and moves up, flow into cushion dashpot, a part of pressure energy saved by spring, and most of concrete materials flows towards conveyance conduit direction simultaneously.When Double-plunger wet-spraying machine is in S Vavle switching interval, the pumping pressure short time decline and close to zero, now the pressure of spring is greater than the pressure of pumping, and the spring pressure energy release of savings, promotes piston the force feed down of the material in cushion dashpot, because the outlet connecting wet-spraying machine is S valve, S valve is almost shutoff at switching interval, so material is towards the motion of conveyance conduit direction, plays the effect of interval make-up pump pressurization pressure and material, thus realize the continus convergence of material, prevent pulse phenomenon from occurring.
The present invention adopts pure frame for movement, does not need to get final product safe and stable operation by automation control appliance.Vibrational power flow is simple, decreases fault origination point, improves stability and the reliability of plant running; Meanwhile, decrease maintenance and repair cost and running cost, reduce the beneficial effects such as equipment manufacturing cost.

Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described in detail.
As shown in Figure 2, the anti-pulser of a kind of Double-plunger wet-spraying machine of the present invention, is arranged between wet-spraying machine and conveyance conduit, and it comprises all flanged (FLGD) tube connector 8 in two ends, cushion dashpot 5, top cover 3, containment vessel 1, spring 7 and piston rod 4.
Above-mentioned tube connector, offers a mouth of pipe along tube wall vertical orientations; The mouth of pipe welds cushion dashpot, and spout diameter equals cushion dashpot cylinder diameter; One end of tube connector is connected with wet-spraying machine, and the other end is connected with conveyance conduit.
The top of above-mentioned cushion dashpot cylinder body is flange face, flange face is provided with top cover, top cover is provided with containment vessel; Top cover, containment vessel and flange face are bolted to connection; Piston rod and spring is provided with in cushion dashpot cylinder body.
Be provided with a through hole in the middle of above-mentioned top cover, through-hole diameter is greater than the diameter of piston rod.
Above-mentioned spring upper end withstands top cover, and piston is withstood in lower end.
Above-mentioned piston rod upper end is through the through hole of top cover, and in " T " font, be hung on top cover, lower end connects a piston, and the soffit of piston flushes with the inner surface of tube connector.
The anti-pulser of above-mentioned a kind of Double-plunger wet-spraying machine, the spring pressure value selected should meet following requirement, and when the soffit of piston flushes with the inner surface of tube connector, the pressure of spring is the half of the specified pumping pressure peak value of wet-spraying machine; When containment vessel is withstood in the upper end of piston rod, the pressure of spring is the peak value of the specified pumping pressure of wet-spraying machine.
When Double-plunger wet-spraying machine pumping pressure is higher than a half of specified pumping pressure peak value, as a section in Fig. 1, because spring pressure value is less than pumping pressure, part concrete materials heads on piston 6 and moves up, concrete materials flows into cushion dashpot 5, a part of pressure energy saved by spring 7, and most of concrete materials flows towards carrier pipe direction, as Fig. 2.When Double-plunger wet-spraying machine is in S Vavle switching interval, the pumping pressure short time decline and close to zero, as b section in Fig. 1, now the pressure of spring 7 is greater than the pressure of pumping, release in the spring pressure energy short time of savings, promote piston 6 the force feed down of the material in cushion dashpot 5, because the outlet connecting wet-spraying machine is S valve, S valve is almost shutoff at switching interval, so material moves towards conveyance conduit direction, play the effect of interval make-up pump pressurization pressure and material, thus realize the continus convergence of material.
