Abstract
The utility model provides a water jet pump which is provided with a pump body. A water absorbing opening, a working water opening and a connecting opening are made on the pump body, the connecting opening is connected with a diffusing pipe, the diffusing pipe is connected with a water outlet pipe, and a nozzle is installed in the pump body. The utility model is characterized in that the central line of the absorbing passage is a straight line which is intersected with the straight line of the nozzle central line, the included angle Alpha between the extended line of the flange end surface of the water absorbing opening and the extended line of the flange end surface of the working water opening is less than 85 degrees. The central line of the absorbing passage is a straight line which is intersected with the straight line of the nozzle central line, namely, the working water passage of the pump body is connected with the water absorbing passage through a straight line, a mixing chamber is formed in the pump body, to enable an optimal cross section rate to be formed at the working water opening and the pump body mixing chamber opening, and the jet resistance is small, thereby ensuring that the drainage and discharging performance reaches the optimal state.
Description
Technical field
The utility model relates to water jet pump, is specially adapted to boats and ships bilge row, hydrophobic, also can be used for suction in the container.
Background technique
Water jet pump utilizes liquid knockout to transmit energy, and it mainly is to increase severely with working pump high pressure water speed when nozzle, forms high speed water and penetrates, and take away the interior air of the pump housing, causes this zone to form vacuum state.Under differential pressure action, taken away together by working water at mixing chamber, discharge, reach hull bottom (or in container) row, hydrophobic purpose from effluent pipe mouth by the liquid pumped.But there are two big defectives in existing jet pump: the one, the end face of flange at the pump housing work mouth of a river become with the end face of flange at the suction mouth of a river 90 ° vertical, this structure is to the bigger narrow limitation of mounting point existence of pump; The 2nd, the working water passage becomes circular arc to intersect with the water absorption channel center line, and hydraulic performance has considerable influence.
Summary of the invention
The purpose of this utility model is in order to overcome the shortcoming that prior art exists, to provide a kind of pump that helps to be installed in the angle of inclination, and it is smooth and easy to flow when sucking, the water jet pump that suction performance is better.
The technological scheme of the utility model water jet pump is: the pump housing is arranged, the pump housing is shaped on and sucks the mouth of a river, the work mouth of a river and connection mouth, connection mouth connects diffuser pipe, diffuser pipe connects outlet pipe, nozzle is installed in the pump housing, it is characterized in that the suction passage center line is that straight line and nozzle center line straight line intersect, sucking the line stretcher of mouth of a river end face of flange and the angle α of work mouth of a river end face of flange line stretcher is less than 85 °.
Water jet pump of the present utility model, the working pump that disposes on the ship is there being the hydraulic pressure of certain flow rate to go into the pump housing, current are when nozzle, sectional area sharply diminishes, flow velocity strengthens, and in nozzle mouth (pump housing connection mouth place) and diffuser pipe generation vacuum, the water at cabin ponding place is inhaled into the pump housing by the work mouth of a river under the barometric pressure effect, water at connection mouth place working pipe and suction pipe converges, have working pump to drive owing to suck the mouth of a river, flow velocity is big, brings the water at the work mouth of a river into diffuser pipe in the lump and ejects from outlet pipe, so repeatedly, till blotting ponding.Nozzle is installed in the pump housing, can be produced the high-speed jet sucking-off and enter air in the pipeline, (making the pressure in the pump housing be significantly less than the outer barometric pressure of pump) falls in boost pressure greatly, suction lift can reach 2-7 rice, even suck air at shoal, do not influence suction, applied widely.Its suction passage center line is a straight line, suction pipe is a straight tube, processing easily, precision can guarantee, itself and nozzle center line straight line intersect, be that pump housing working water passage is connected with straight line with the suction water channel, in the pump housing, form a mixing chamber, make the work mouth of a river and optimum section ratio of pump housing mixing chamber interruption-forming, jet resistance is little, thus the row of making, hydrophobic performance reaches the optimum state, sucking the line stretcher of mouth of a river end face of flange and the angle α of work mouth of a river end face of flange line stretcher is less than 85 °, the working pump setting angle is flexible, can be installed in the angle of inclination, is applicable to various layout demand on the ship.
Water jet pump of the present utility model, its described suction mouth of a river end face of flange line stretcher is 30 °～85 ° with the angle α of work mouth of a river end face of flange line stretcher, is convenient to the installation of working pump.
Description of drawings
Fig. 1 is the structural representation of the utility model water jet pump.
Embodiment
The utility model discloses a kind of water jet pump, as shown in Figure 1, the pump housing 4 is arranged, the pump housing is shaped on and sucks the mouth of a river 2, the work mouth of a river 1 and connection mouth 3, connection mouth connects diffuser pipe 6, diffuser pipe connects outlet pipe 7, nozzle 5 is installed in the pump housing 4, and its major technology is characterised in that suction passage center line 8 is that straight line and nozzle center line 9 straight lines intersect, and suction pipe and nozzle are straight tubes, processing easily, precision can guarantee, and can make jet smooth and easy by suction pipe, and the line stretcher 12 that sucks mouth of a river flange 10 end faces is less than 85 ° with the angle α of work mouth of a river flange 11 end face line stretchers 13, working pump mounting point wide adaptability is applicable to various layout on the ship.During work, the work water pump acting back that carries on the ship produces certain pressure, flow velocity, water with certain pressure, flow velocity enters and sucks the mouth of a river 2, during the nozzle at connection mouth 3 places that flow through, because sectional area diminishes suddenly, forming high-speed jet makes nozzle 5 oral areas and diffuser pipe 6 produce vacuum, ponding enters diffuser pipe 6 from the work mouth of a river 1 under vacuum action, fully mix with high-velocity flow in diffuser pipe 6, ejects after being brought into water outlet diffusing tube 7, so repeatedly, blotted up to ponding.This water jet pump, the degree of depth of suction ponding is a 2-7 rice, also can suck air at shoal, does not influence suction, and is applied widely.Its described suction mouth of a river flange 10 end face line stretchers 12 are 30 °～85 ° with the angle α of work mouth of a river flange 11 end face line stretchers 13.
