试压泵是各类压力容器、管道、阀门、锅炉、钢瓶、消防器材等作水压试验和实验室中获得高压液体的检测设备,按驱动来分常用的分为几大类：手动，电动，气动，液压，柴油，数控等.
Pressure test pump is designed for all kinds of pressure vessels, pipelines, valves, cylinders, boiler, fire equipment for testing equipment for high pressure liquid hydrostatic test and laboratory, by driving to the most commonly used is divided into several categories: manual, electric, pneumatic, hydraulic, diesel, numerical control and so on.
从操作方式来分，试压泵分为三种：电动试压泵、手动试压泵和电动手提式试压泵。测试电动泵用于填充或测试各种水，防冻液和油系统。从振动提供了可靠的保障。体积小，重量轻，该设备是容易使用。所有工作部件是由不锈钢和黄铜。

From the way of operation, the pressure pump is divided into three kinds: electric pressure test pump, manual test pump and electric portable pressure test pump. Test electric pumps for filling or testing various water, antifreeze, and oil systems. Provides a reliable guarantee from vibration. Small in size and light in weight, the device is very easy to use. All work parts are made of stainless steel and brass.
电动试压泵属于往复式柱塞泵，电机驱动柱塞，带动滑块运动进而将水注入被试压物体，使压力逐渐上升。该机由泵体、开关、压力表、水箱、电机等组成试压泵具有结构紧凑、合理、操作省力、整机重量轻、维修方便、防锈、3DSY系列电压试压泵采用电机驱动，大大地提高工作效率等特点。
The utility model relates to an electric pressure testing pump, belonging to a reciprocating plunger pump, wherein, the motor drives the plunger to drive the slide block to move, and the water is injected into the object to be pressed, so that the pressure is gradually increased. This machine is composed of a pump body, a switch, a pressure gauge, water tank, motor and other components of the pressure test pump has compact and reasonable structure, easy operation, light weight, convenient maintenance, anti rust, 3DSY series voltage test pump driven by the motor characteristics, greatly improve work efficiency.
结构及工作原理：1.检查水箱中水位，连接电源线。2.顺时针拧紧手轮开关。3.按启动按钮，电机工作，当压力表指针达到调定的额定压力时，压力不会上去。4.试压结束后，逆时针拧松开关，介质流回水箱。
Structure and working principle: 1. check the water level in the water tank and connect the power cord. 2. tighten the handwheel switch clockwise. 3. press the start button, the motor work, when the pressure gauge pointer to adjust the rated pressure, the pressure will not go up. 4. after the end of the pressure test, unscrew the switch counterclockwise and return the medium to the water tank.
注意事项：1.使用前，将开关顺时针拧紧。2.使用的工作介质必须100目/寸滤网过滤后才能注入水箱，吸入口不能漏出水面。3.不宜在有酸碱、腐蚀性物质的工作场合使用。4.停止使用后，应用煤油或火油作介质过滤一下。5.电动试压泵不能没有水负载。
Note: 1., before use, first turn the switch clockwise. 2., the working medium must be 100 mesh / inch filter screen, filter can be injected into the water tank, the suction port can not leak out of the water. 3., should not be in the acid-base, corrosive substances used in the workplace. The 4. stop after use, using kerosene or kerosene as filtering medium. 5., the electric pressure pump can not do without water load.
