Three cylinder piston pump work features and precautions

[Asia Pump Network News] three-cylinder piston pump to take the three major joint work of the piston pump, so we call it a three-cylinder piston pump. Three-cylinder piston pump is mainly used for conveying and spraying all kinds of dry mortar. Because of the three-cylinder piston pump with large flow, high pressure, stable performance and other characteristics, so it's a very wide range of applications. Three-cylinder piston pump three-cylinder piston pump pressure range can be achieved 0-30MPa, self-priming capability. However, the three-cylinder piston pump also has some disadvantages, its structure is more complex, displacement is small. Three-cylinder piston pump consists of SEG piston pump, the three pumps in parallel with a row of three cylinders, three connecting rod with a crankshaft mounted on each other to form a 120-degree angle. The piston of the three-cylinder piston pump also doubles as a water inlet valve. The inlet valve group consists of a flat valve plate, a plastic bowl holder, a plastic bowl, a triangular sleeve and a suction valve plate. Plastic bowls, flat valves and inlet valves are mounted on the piston rod, the piston in addition to moving with the piston rod, the plastic bowls on the piston rod can make a small amount of axial movement, play the role of inlet valve. The front end of the cylinder is equipped with a water outlet valve. Normally, the outlet valve is closed under the action of a spring and only opens when the liquid pump is drained. Three-cylinder piston pump in the operation need to pay attention to the following points: 1, first check before starting oil, water tank is lack of oil or water. 2, check before starting spray gate has been opened. 3, must be venting to avoid cavitation before starting. 4, first for the pump after the pump to avoid dry piston. 5, regular cleaning tank, waterway. 6, no pressure start. 7, in operation if the pressure gauge swing or abnormal sound immediately shut down test. 8, the use of 90mm cylinder pressure pump can not exceed 20MPa. 8, the use of 100mm cylinder pressure pump can not exceed 16 MPa. One of the advantages of the three-cylinder piston pump is a wide range of pressure regulator, but in the process of regulating pressure should pay attention to the control of the pressure value, otherwise it is easy to cause some damage to the machinery. Only pay attention to the routine maintenance of machinery, machinery can achieve the best state, in order to extend the service life. Industry Internet (Xiamen) Technology Co., Ltd.
