1 oil spill: check shaft seal, the sealing parts, adjust or renewal. Hard sealing butterfly valve vacuum is not high: Cnc Machining Center,Vertical Machining Center,Small Cnc Machining Center,Cnc Vertical Machining Center Taizhou Jiangzhou CNC Machine Tool Manufacturing Co.,Ltd , https://www.tzjzmachine.com
2 Noise: abnormal noise: check whether foreign objects fall into the pump chamber, bearings, pump drive parts for damage. Clear, trim, change new.
3 fuel injection: a large number of oil spouts: check the oil level is too high, such as too high, release; retaining cover components, anti-injection components are intact.
4 Blind valve vibration: a lot of vibration: Check the base is solid, fastened, the foundation is sufficient. Have bite, stuck in the early signs, adjust.
5 pump temperature anomalies bearing fever: a little loose belt, check whether the smooth flow of oil, cooling water enough. Fuel tank heat, exhaust valve overheating: reduce the inlet pressure, increase the amount of cooling water.
6 bite stuck: check whether foreign objects fall into, parts intact, lubrication is adequate, fuel, oil, pumps.
7 electric shutter valve motor current is too large or fuse blown: check the current is too large reason, check the fuse capacity, adjust, change new.
(1). Pump leaks.
(2) cartridge hole suction, appear mist: cleaning oil filter, check tubing, pumps.
(3) pump oil pollution: open the gas valve running 1-2 hours or longer, or new oil.
(4). Insufficient fuel, the oil level is too low: fuel.
(5). Oil temperature is too high: Increase the amount of water, reduce the ambient temperature and inhaled gas temperature, eliminate occlusion, poor lubrication.
(6). Exhaust valve damage: for the valve.
(7). Exhaust valve spring damaged: renewal.
(8) parts of the pump wear and tear, there are different sound, power abnormalities: dismantling inspection of the rotating parts.
