Hello! Thank you for choosing our products. 3D-SY series of ultra-high pressure pump is one of our newly improved range of products. According to the information fed back to the user, this series UHP pumps industrial operation, the original dirty because the test medium affect valve is working properly. Now increase the pump outlet check valve, relief valve mounted on the front of the check valve to avoid the test medium through the pump back into the tank, thus protecting the pump valve no longer affect soil medium. In addition, the original pump installed safety valve when the system is overloaded play a protective role. First, use 3D-SY series of ultra-high pressure pumps can meet a variety of vessels, piping, valves for pressure test and burst test, the test pressure may rise in atmospheric rated discharge pressure. The transmission medium typically pumps the emulsion, the water can also be used rust and neutral oil emulsion with viscosity similar to, a temperature of 5 ~ 60 ℃. Second, the main structure and working principle of the pump is horizontal three plunger pump, the motor, pulleys, racks, head and base composition. 1, the frame is made of the body, crankshaft, connecting rod, crosshead and other components. Decelerate the motor through the pulley and crank link mechanism through a rotary motion into reciprocating linear motion of the crosshead. Cast iron body is a box-shaped structure, the front end of the boring has three mounting holes to ensure concentricity of the plunger and crosshead, rear fuselage has a rectangular opening holes for crosshead, connecting rods and other parts of the equipment demolition. Crank a monolithic three Abduction. The connecting rod is split at the structure, with a standard of 175 diesel engine connecting rod bearings, rod small head with a copper bearing and cross pin connections. Crosshead cylindrical structure, and both end faces of the cross pin fitting hole fitted snap ring to prevent the crosshead pin to move the crosshead with the plunger coupling using intermediate spherical structure, to ensure the automatic positioning of the plunger. 2, head head by the pump, suction valve, discharge valve, piston deputy and other parts. Pump fixed in the body, the crosshead driving the plunger reciprocates in the pump body, so that the working volume of the pump body produces cyclical changes. When the suction stroke of the plunger, the inner volume of the pump increases, the discharge valve is closed, a partial vacuum is formed, the working medium at atmospheric pressure, the suction valve into the pump body; conversely, the suction valve is closed, the working medium is discharged from the valve output, after a single the valve into the delivery conduit from the external device to be tested, until the desired pressure. In addition, the check valve on the right side of the pump head is equipped with a visual gauge to monitor the discharge pressure of the pump.
