2D-SY oil prohibition electric Pressure test pump 2D-SY type (6.3-80MPa) electric pressure test pump , mainly used for various pressures container , Oxygen Gas cylinder 、 The Conduit , valves, steam boilers, etc. for hydrostatic test, new pre stress processing technology and equipment for obtaining liquid high-pressure source in the laboratory. It is a relatively new series of products designed by the pressure test pump joint design team of the General Machinery Research Institute of the Ministry of Machinery Industry. It has the characteristics of the old products, such as high degree of "three modernizations", long service life, stable performance, flexible movement and light weight. On this basis, the transmission device and cross conversion are added, so that the comprehensive value of this series of products can meet the requirements, and all kinds of performance are stable and reliable, It is safer and more convenient to use, and achieves the effect of energy saving and electricity saving. In terms of product structure, closed water tank is selected to reduce the height of the whole machine and make the appearance more compact and beautiful. The product is specially designed with water at 5 ° - 60 ℃, emulsion and oil with viscosity no more than 45mm2/s as working medium. The working environment temperature of the pump is 5 ° - 60 ℃.
The product is a horizontal 2-cylinder reciprocating pump. It is composed of motor, reduction gearbox, transmission case, water cylinder, water collector, safety valve, water tank and other main components. The pump is installed on the water tank cover, and there are four rollers under the water tank, so that the pump can move flexibly. The motor and reducer are connected by two half couplings. The speed ratio of the worm gear shaft to the worm gear in the reduction gearbox is 2:55. Both ends of the worm gear shaft are equipped with eccentric shafts that form 180 ° with each other. Through the sliding mechanism in the transmission boxes on both sides, the rotary motion is transformed into the reciprocating motion of the slider and crosshead. The plunger installed on the crosshead reciprocates in the water cylinder to realize the alternate suction and discharge process of the pump. Under the reciprocating action of the plunger, the working volume in the two water cylinders changes periodically. When the plunger is in the suction stroke, the outlet valve is closed. With the increase of the working volume of the water cylinder, a vacuum is formed in the cylinder. Under the action of atmospheric pressure, the working medium in the water tank enters the cylinder through the filter screen, the water inlet pipe, and the jacking water inlet valve. When the plunger is in the discharge stroke, the water inlet valve is closed and the water outlet valve is forced to open. The plunger will input the working medium into the water collector through the water outlet valve and deliver it to the container under test to realize pressure test.
