Three Cylinder Electric Pump Common Faults and Solutions

[Asia pump network hearing] Three-cylinder electric pump in the use of some faults may occur, learn to handle their own in order to improve work efficiency. Xiaobian now inventory the three-cylinder electric pump common failures and solutions. Three-cylinder electric pump Three-cylinder electric pump common faults and solutions Fault phenomenon Cause Remedy Motor can not start the power supply or line failure Check the power supply conditions and line flow and pressure fluctuations in the lack of excessive 1, excessive inhalation 2, Filter plugging 3, the inlet pipe leaks or inlet pipe joints at the poor seal 4, a cylinder or two cylinder inlet and outlet valve stuck or failure 1, to improve the level of the inlet 2, clear the filter plug 3, change into Water fastening joints 4, overhaul grinding or replacement valve system pressure does not go 1, the plunger seal leakage too large 2, the safety valve leakage 3, the pressure relief valve failure, closed lax 4, gauge damage 1, Adjust the compression nut, after adjusting the margin several times, should replace the new seal packing 2, readjust or replace the safety valve spool, valve seat 3, replace the relief valve core, valve seat 4, replace the pressure gauge overflow The valve can not boost pressure, while its overflow can not be closed 1, the spring failure 2, overflow spool failure 1, replace the spring 2, replace the relief valve spool, the valve seat can not keep pressure after shut down ) 1 , Check valve failure 2, relief valve failure 3, check the pressure relief valve O-ring damage 1, grinding repair Check valve, valve seat or replacement 2, grinding repair pressure relief valve, valve seat Or replacement 3, replace the corresponding O-ring Metal pump hammer in operation 1, connecting rod, cross head and other transmission parts wear gap is too large 2, bearing gland gap adjustment is not appropriate 3, the bearing failure 1, repair or replacement 2 , Adjust the bearing gland gap 3, replace the bearing temperature in the transmission box is too high 1, excessive or insufficient oil 2, lubricating oil is polluted or deteriorated 3, the oil does not meet the requirements 1, release excess oil or add enough lubrication oil, oil standard oil level to maintain the intermediate position 2, 3 replacement of oil, lubricants expand the use of reasonable reading: pump valve pipe fittings exhibition 2016 exhibition of information industry, Internet (Xiamen) Technology Co., Ltd. author: Asian pumps network editor: Yao Xiaoxia (QQ / WeChat:) http://beng.liuti.cn/ (Service Hotline:)
