Parker variable displacement piston pump pv092r1k1t1nmmc

parker Variable displacement piston pump PV092R1K1T1NMMC High pressure 、 Compact structure 、 Efficient 、 The secondary adjustment is convenient , Therefore, it is widely used in construction machinery 、 mine 、 Metallurgy and other industries .

because parker Variable displacement piston pump PV092R1K1T1NMMC Very sensitive to oil contamination , And there are higher requirements for the piping in the hydraulic system and the installation of the pump itself , therefore parker The pump has a high failure rate , To ensure the service life of the pump , Must be in the design of the hydraulic system 、 Conduct standardized operation during piping installation and site commissioning .

One 、parker Problems needing attention in installation and commissioning of variable displacement piston pump

1.parker Variable displacement piston pumps can be stabilized by manufacturing or by flange mounting 、 strong 、 Good rigidity and vibration absorption .

2.parker Variable displacement piston pump PV092R1K1T1NMMC The oil absorption resistance shall not be too large , Otherwise, Party B will produce the illusion of air turbidity . The plunger pump is allowed to operate at 110 Suction under a vacuum of millimercury . The distance between the center of the variable piston pump and the liquid level shall not exceed 500 mm . To avoid inhaling dirt or impurities , When the oil absorption is reduced , The filtration precision shall be increased to 100~15μm Filters in range , The rated flow rate of the filter shall not be less than that of the variable displacement piston pump 2 Multiple flow rate .

3.parker Variable displacement piston pump PV092R1K1T1NMMC Connecting flange at oil suction port 、 The first stage of the joint and the whole oil suction pipe must be tightly sealed , To prevent air leakage , Otherwise, it will cause noise 、 When the system vibrates and is used, a large number of bubbles are generated in the oil tank , The service life of the plunger pump is reduced .

4.parker Variable displacement piston pump PV092R1K1T1NMMC The diameter of the oil suction pipeline shall not be less than the diameter of the pump inlet , Only one elbow is allowed in the oil suction pipeline at most .

5. Separators shall be provided internally , To separate bubbles and pollutants caused by oil return . The oil return pipe and oil drain pipe shall be located below the oil level of the sound channel , To prevent the return oil from splashing bubbles .

That's all parker Variable displacement piston pump PV092R1K1T1NMMC Some simple sharing of relevant content , Pay attention to Ningbo Sicheng , Take you to know more about imported hydraulic knowledge and content .
