Problems solved by technology

The traditional three-phase motor drives the plunger to reciprocate through the pulley and the reduction box. When the controller issues a command to stop pressurization during use, due to the inertia of the motor, it will drive the plunger for several more strokes, causing the pressure to be higher than the control. The upper limit, which makes the test results deviate from the actual value

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 [0001] The invention relates to a pressure water pump for an anti-seepage instrument, specifically, it is mainly used for the test of the anti-seepage performance of concrete and the determination of the anti-seepage label; at the same time, it can also be used for the measurement and quality inspection of the air permeability of building materials, which belongs to the measuring instrument technology field. Background technique [0002] The anti-seepage instrument is an important equipment for testing in cement plants, scientific research institutions and other units. Before the present invention was made, among the existing technical products in China, the high-pressure water pump of the anti-seepage instrument was driven by a traditional three-phase motor through a pulley and a reduction box. The reciprocating motion of the plunger provides high pressure water. In the process of use, it often occurs that the pressure is overshoot or the belt is loose and ...
