Specific embodiment

Fig. 1, Fig. 2 are referred to, the lapping liquid draw-off pump of the utility model offer is provided, it is mounted on one and stores lapping liquid On 33 reservoir 3, wherein the lapping liquid 33 contains the subparticle for grinding and aqueous or oil for grinding and lubricating Liquid.The draw-off pump includes a motor 1, and the motor 1 stretches out a rotating shaft 11, and a pump housing 2 is connected to the motor with a pillar 20 1.The pump housing 2 is provided with an interior room 21, and is communicated with a delivery port 22 and a water inlet 23 in the interior room 21, for lapping liquid 33 enter the interior room 21 from the water inlet 23, and are discharged from the delivery port 22；In the present embodiment, the delivery port 22 is connected with one Outlet pipe 221, is used to guide the lapping liquid of discharge to workpiece.

A rotatable leaf fan 24 is provided with the interior room 21, wherein leaf fan 24 is connected with the rotating shaft 11 of the motor 1, and can Rotated by the driving of the motor 1, so drive lapping liquid in the interior room 21 from the center of rotation of leaf fan 24 radially towards Outer flowing.Driven what is formed to flow by leaf fan 24 in the interior room 21 by the above-mentioned lapping liquid, in making the interior room 21 Defined at the center of rotation near leaf fan 24 and be formed with a low-pressure area 25, and away from the rotation of leaf fan 24 in the interior room 21 Then define and be formed with a higher-pressure region 26 in center.

Hold, on the pump housing 2 to should the position of higher-pressure region 26 be provided with several ejiction openings 27, wherein each ejiction opening 27 runs through The pump housing 2, and it is communicated to the interior room 21.In the present embodiment, the pump housing 2 has a bottom wall 28 and a perisporium 29, the wherein bottom Wall 28 is corresponding with the bottom surface 31 of the reservoir 3, and the perisporium 29 is corresponding with the side 32 of the reservoir 3, and the ejiction opening 27 is located at On the bottom wall 28 and the perisporium 29 to should higher-pressure region 26 position.

By the utility model of said structure and configuration composition when actually used, as shown in Fig. 2 the pump housing 2 sinks to In lapping liquid 33 in the reservoir 3, when the motor 1 drives the rotating shaft 11 and drives the leaf to fan 24 rotation, in the interior room 21 Foregoing higher-pressure region 26 and low-pressure area 25 is formed, lapping liquid 33 is then sucked into the low-pressure area of the interior room 21 through the water inlet 23 25, then flowed toward higher-pressure region 26.Now, lapping liquid can more pass through in addition to discharging the interior room 21 by the delivery port 22 Ejiction opening 27 on the bottom wall 28 and perisporium 29 of the pump housing 2 discharges the interior room 21；Further, because each ejiction opening 27 is set Position be located at higher-pressure region 26, therefore lapping liquid is erupted with a relatively high pressure from each ejiction opening 27.And sprayed through each ejiction opening 27 The lapping liquid F for going out will form impact and constitutes flow-disturbing to the lapping liquid 33 in the reservoir 3, or even clash into the bottom of the reservoir 3 Rebound again and form bigger flow-disturbing effect behind face 31 and side 32.

Above-mentioned flow-disturbing effect will stir the lapping liquid 33, evoke the subparticle for being deposited on the bottom of reservoir 3, make it It is uniformly distributed in the lapping liquid 33 and concentration is tended to uniform.Accordingly, the lapping liquid extracted out through the delivery port 22 by the pump housing 2 To be the lapping liquid of even concentration, it contains enough subparticles, and is available for the grinding operation of rear end to be smoothed out, and ensures The quality of grinding.
