Description
Technical field
The utility model relates to the grouting pump technical field, relates in particular to a kind of grouting pump screw type supercharging device.
Background technique
Domestic existing grouting pump manufacturer is more, and using has two kinds more widely, is respectively piston type grouting pump and extruding type grouting pump.
Come with some shortcomings in the actual use of the grouting pump of above-mentioned two kinds of structures: the pulsating pressure of piston type grouting pump is strong, and easily the plugging booster, be difficult to pour into thick slurry;
The pressure of extruding type grouting pump is less than normal, and rate of fault is higher, also is difficult to pour into thick slurry, and sealing effect is poor, and effective discharge is low, easily immerses air.
Therefore both are discontinuous when carrying cement slurry (slush), and pulse is arranged, and can not pour into the thicker cement slurry of viscosity (slush).
The model utility content
The purpose of this utility model is to provide a kind of grouting pump screw type supercharging device, to solve the technical problem that the output of grouting pump slurry is discontinuous, pressure is little of existing use.
The utility model is to realize like this, a kind of grouting pump screw type supercharging device, comprise outer tube body, be installed with the bull stator sleeve that elastomer is made in described outer tube body, be rotatablely equipped with multi-start worm in described bull stator sleeve, a number of described bull stator sleeve and described multi-start worm is unequal, and the variation space between described multi-start worm and described bull stator sleeve forms the supercharging storehouse that slurry flows, and the two ends in described supercharging storehouse are provided with adpting flange.
As improving further, described bull stator sleeve is three stator sleeves, and described multi-start worm is two worm screw.
As improving further, described bull stator sleeve is bull elastomer stator cover.
After having adopted technique scheme, the beneficial effects of the utility model are: due to after grouting pump adopts screw type supercharging device slurry body to coordinate between namely using multi-start worm and the bull elastomer stator overlapping, exist matching gap namely to form the supercharging storehouse, enter like this slurry in the supercharging storehouse just along continuous being transferred away of continuous variation in gap, supercharging storehouse, thereby solved the device problem of slurry body continuously of the slurry body of existing use, easy to use, efficient is high.
Owing to adopting three elastomer stator covers and two worm screw, can obtain so maximum most suitable matching gap, thereby for the slurry that sucks provides enough flowing spaces, reasonable in design, using effect is good.

Embodiment
In order to make the purpose of this utility model, technological scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
As shown in Fig. 1, Fig. 2 and Fig. 3 are common, a kind of grouting pump screw type supercharging device, comprise outer tube body 4, be installed with the bull stator sleeve that elastomer is made in outer tube body 4, be rotatablely equipped with multi-start worm in the bull stator sleeve, a number of bull stator sleeve and multi-start worm is unequal, and the variation space between multi-start worm and bull stator sleeve forms the supercharging storehouse that slurry flows, and the two ends in supercharging storehouse are provided with adpting flange; The bull stator sleeve is three elastomer stator covers 3, and described multi-start worm is two worm screw 2.
At first the utility model is designed to two right-handed thread with supercharging worm screw 2 in use, and lead of screw thread is 126mm, and tooth depth is 11mm, and reach is 480mm, as shown in Figure 2;
then above-mentioned elastomer stator cover 3 is combined together with worm screw 2, because both all have the groove structure, therefore exist each other matching gap namely to form the supercharging storehouse after coordinating, so just can be along Clearance Flow between the two by the slurry 7 such as the mortar that inject in the grouting pump pipeline, due to worm screw 2 by screw rod 6 driven rotary in grouting pump, and elastomer stator cover 3 maintains static, so the gap between elastomer stator cover 3 and above-mentioned worm screw 2 constantly changes, and the existence that always keeps the gap, be inhaled into like this flowing that mortar in the above-mentioned gap just can be continuous, and the rotation along with worm screw 2, the pressure of the mortar in the supercharging storehouse that enters constantly increases, further guaranteed the outflow from go out slurry 5 that mortar can be continuous, easy to use.
The process that above-mentioned mortar is inhaled into the supercharging storehouse is as follows: injected water cement mortar in hopper, closed grouting pump power switch of while also begins the operation of being in the milk, this moment motor to begin to drive speed reducer, transmission shaft and conveying screw be screw rod 6, conveying screw rotates by the grouting direction, the worm screw 2 that drives simultaneously supercharging is rotated, the sectional shape of worm screw 2 cooperation places of elastomer stator cover 3 and supercharging is constantly changed, and the slush of injection just can be inhaled in the supercharging storehouse, as shown in Figure 4 like this.
The above-mentioned slush that is inhaled in the supercharging storehouse, along with the continuous rotation of the worm screw 2 of supercharging, the pressurization step by step as shown in Figure 5 of having arrived, the output procedure as shown in Figure 6 of having arrived afterwards, thus reach the purpose that supercharging is carried;
After the grouting operation is completed, can press the grouting pump stop button as the need pressurize, this moment, motor stopped operating, but the slush in delivery line still keeps certain pressure, reaches the purpose of pressurize;
When needing pressure release in the grouting operation process, press stop button, press again pressure relief press button, this moment, motor was by the pressure release direction rotation, just in time opposite with pressurization, slush in above-mentioned supercharging storehouse is inhaled into gets back to the guide storehouse, thereby the slush pressure in the supercharging storehouse is discharged, thereby reaches the purpose of pressure release.
A kind of grouting pump screw type supercharging device that the utility model provides, comprise outer tube body, be installed with bull elastomer stator cover in this outer tube body, this bull elastomer stator cover internal clearance cooperation is provided with multi-start worm, variation space between this multi-start worm and above-mentioned bull elastomer stator cover forms the supercharging storehouse of slurry flow path, and the two ends in this supercharging storehouse are provided with adpting flange, and the formation in above-mentioned supercharging storehouse can be so that grouting pump continuous wave output slurry, efficient is high, and is easy to use.
The above is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
