2015 Model test pump manufacturers test pump pressure test pump control system manufacturers

3D-SY200 series of ultra-high pressure pump 3D-SY series UHP 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 technical parameters Model Rated working pressure MPa Flow L / h Plunger diameter mm Stroke mm matching motor type, power dimensions (length X width X height) mm Weight Kg 3D-SY100 MPa 100 122 12 40 Y132 M2-6 5.5Kw 1690X675X1000 630 3D-SY125 MPa 125 84.7 10 3D-SY160 MPa 160 68.7 9 3D-SY200 MPa 200 54 8 Third, the main structure and working principle of the pump is horizontal three plunger pump, the motor, pulleys, racks, pump 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. The left end of the pump head is equipped with a safety valve, for protection when the system is overloaded. Take off the pressure relief valve is adjusted at the factory is good, it can not arbitrarily transfer. The use of methods and precautions 1, use a, slow down box to add a little oil, so the oil reaches groove on the oil standard height, lubricants No. N68 machine oil (equivalent to the old grade 50 machine oil). Join the plunger inside the No. N46 machine oil (equivalent to the old 30th grade machine oil), oil reaches the center of the height of the plunger. b, check the transmission part of the connecting bolt without loosening. c, whether mounted inside the transmission medium at room temperature sufficient to check the tank. Interface should be up to the water mark limit. d, pulled pulley revolutions, checking the machine during operation, organization or without jamming or collision, while checking the seal compression nut without loosening. e, the test device will be connected to the system better.
