Abstract
The invention relates to a pressure water pump for an impermeability instrument. The pressure water pump comprises a hysteresis synchronous motor, bearings, a crank shaft, a speed reducer casing, a plunger, a pump, a linkage mechanism, a cover plate and a bearing cover. The hysteresis synchronous motor is mounted on the speed reducer casing through a flange and is connected with the crank shaft, the linkage mechanism is sleeved on the crank shaft which is supported in the speed reducer casing by the aid of the bearings, the bearings are covered with the bearing cover which is fastened on the speed reducer casing through bolts, the pump is fastened on the speed reducer casing through bolts, and the plunger is connected with the linkage mechanism. The crank shaft and the linkage mechanism drive the plunger to reciprocate in the pump when the motor rotates, and the speed reducer casing is covered with the cover plate. By means of the pressure water pump, the pressure control accuracy of the impermeability instrument can be improved, a belt transmission link is omitted, the water pump can stop operating timely, the overshoot of pressure is prevented, and the operational reliability can be improved.
Description
Technical field
The present invention relates to a kind of Anti-leakage instrument pressure water pump, be specifically mainly used in the test of concrete impermeability and the mensuration of anti-penetration grade; Also can utilize it to do mensuration and the quality inspection of structural material gas permeability, belong to surveying instrument technical field simultaneously.
Background technique
Anti-leakage instrument is the do experiment visual plant of use of the units such as cement plant, scientific research institution, before the present invention makes, in existing technical products, the high-pressure water pump of Anti-leakage instrument is used traditional three phase motor to drive plunger to-and-fro motion that high pressure water is provided by belt pulley, speed reducer at home.In use, often occur that pressure overshoot or belt slack beat the not situation of upward pressure.Use traditional three phase motor to drive the reciprocating structure of plunger by belt pulley, speed reducer, in use, when controller sends while stopping pressurizeing instruction, due to motor inertia, can drive how several times stroke of plunger, build-up of pressure, higher than upper control limits, makes test result and actual value produce deviation.
Summary of the invention
The object of the invention is to overcome above-mentioned deficiency, a kind of Anti-leakage instrument pressure water pump is provided, can improve the pressure controling precision of Anti-leakage instrument and remove belt transmission link from; Water pump can be quit work in time, avoid pressure overshoot; And can improve functional reliability.
According to technological scheme provided by the invention, a kind of Anti-leakage instrument pressure water pump comprises hysteresis synchronous motor, bearing, bent axle, reducer shell, plunger, the pump housing, linkage mechanism, cover plate and bearing cap; Described hysteresis synchronous motor is arranged on reducer shell and is connected with bent axle by flange, linkage mechanism is enclosed within on bent axle, bent axle relies on bearing to be bearing in reducer shell, bearing cap covers on bearing, by screw fastening on reducer shell, the pump housing is by screw fastening on reducer shell, and plunger is connected with linkage mechanism; During electric machine rotation, bent axle and linkage mechanism drive plunger to-and-fro motion in the pump housing; Cover plate covers on reducer shell.
As a further improvement on the present invention, the described pump housing is provided with lower intake; Water absorbs water by the lower water intake on the pump housing, from upper water-out mouth, pumps high pressure water, completes pressure process.
Compared with the prior art the present invention has the following advantages:
Compact structure of the present invention, reasonable; Use hysteresis synchronous motor is controlled, and mounting type adopts flange to install, and has removed belt transmission link from; Utilize the self-locking performance of hysteresis synchronous motor, make monitoring control devices stop pressurizeing after instruction to sending after pressure reaches setting value, motor can quit work immediately, there is no the inertia of common electric machine; Water pump can be quit work in time, avoid pressure overshoot.Due to the slow-speed of revolution (60RPM) of motor, also lower by the rotating speed after pulley decelerates than common electric machine, by direct flange, be arranged on speed reducer, saved belt wheel and belt, avoided belt long easily lax defect service time.The present invention improves the pressure controling precision of Anti-leakage instrument and reduces transmission link, improves functional reliability.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
The present invention is below further described in connection with the embodiment in accompanying drawing:
As shown in Figure 1, comprise hysteresis synchronous motor 1, bearing 2, bent axle 3, reducer shell 4, plunger 5, upper lower intake 6, the pump housing 7, linkage mechanism 8, cover plate 9 and bearing cap 10.
Described hysteresis synchronous motor 1 is arranged on reducer shell 4 and is connected with bent axle 3 by flange, linkage mechanism 8 is enclosed within on bent axle 3, bent axle 3 relies on bearing 2 to be bearing in reducer shell 4, bearing cap 10 covers on bearing 2, adopt screw fastening on reducer shell 4, the pump housing 7 is by screw fastening on reducer shell 4, and plunger 5 is connected with linkage mechanism 8; Cover plate 9 covers on reducer shell 4.The described pump housing 7 is provided with lower intake 6.
Working principle of the present invention: hysteresis synchronous motor 1 is arranged on reducer shell 4 and is connected with bent axle 3 by flange, and linkage mechanism 8 is enclosed within on bent axle, during electric machine rotation, bent axle and linkage mechanism drive plunger 5 in the interior to-and-fro motion of the pump housing 7; Water, by the lower water intake water suction 6 on the pump housing 7, pumps high pressure water from upper water-out mouth, completes pressure process; When instrument pressure reaches setting value, hysteresis synchronous motor is stall immediately.
Concrete, mortar are the artificial stone materials being widely used in modern architecture.For some building, as waterwork, under water, in water, underground and other construction engineering, require building to there is special performance---impermeability.So-called impermeability refers to that material that structure are used can resist the performance that water or other liquid (light oil, heavy oil) medium permeate under pressure.
The present invention is widely used in the unit laboratories such as cement plant, R&D institution, relevant professional universities and colleges, is mainly used in concrete and the test of mortar impermeability and the mensuration of anti-penetration grade; Also can utilize it to do mensuration and the quality inspection of structural material gas permeability simultaneously.
Anti-leakage instrument meets the standard-requireds such as GB/T50081-2002 < < Standard for test methods of mechanical properties of ordinary concrete > >, T0528-94, GBJ81-85.
