One. No oil or less oil Production reasons:
1, the inhalation height exceeds the rated value 2, the suction pipe leakage 3, the rotation direction is not 4, the suction pipe is blocked or the valve is closed 5, the safety valve stuck or injury 6, the liquid temperature is low and the viscosity increases Exclusion:
1, increase the level of inhalation 2, check the joints, the best sealing material seal 3, then pump the direction shown to correct 4, check the pipeline is blocked, the valve is open 5, open the safety valve cleaning and fine sand grinding sand Grinding valve hole, using anastomosis 6, preheat the liquid or reduce the pressure to exclude two. Leakage seal production reasons:
1, seal wear 2, packing seal packing wear 3, mechanical seal wear or scratches and other defects 4, mechanical seal spring failure to exclude:
1, replace the sealing ring 2, adjust the packing gland tightness, replacement or replacement packing 3, replacement or re-grinding 4, replacement of three. Noise or vibration Production reasons:
1, the suction pipe and filter plugging 2, the suction pipe into the liquid surface shallow 3, the air into the pipe 4, the exhaust pipe resistance is too large 5, gear bearings or side panels severe wear 6, the viscosity of inhaled liquid is too large 7, Inhalation height exceeds the rated value Remedy:
1, to eliminate gear pump dirt on the filter 2, the suction tube growth below the level of the liquid 3, check the connections to seal it 4, check the discharge pipe and the valve is clogged 5, remove the cleaning, and trim defects or replace 6 , Heating viscosity reduction or treatment 7, reduce the suction height and shorten the suction pipe length
After more than 20 years of continuous development, Zhejiang jinteng Machinery Manufacturing Co., Ltd. has become a famous production base and supporting center of screw and barrel for plastic machinery in China.
