How to maintain smooth water chiller system to stop

Chiller is running in the system, pay close attention to more is refrigerator, frozen water cycle system refrigerant cycle system and electric control system of three local, and smooth system is often neglect the object. Little imagine, this system for water chillers, is also very important. Cold water machine the smooth part of the problem does not belong to smooth the system itself, but also will cause system problems. Such as cylinder piston ring structure selection, improper processing and assembling can form a large number of oil phenomenon, and abnormal leakage of shaft seal will be landed the crankcase CPC surface, obviously, which cause the oil pump suction empty phenomenon; Such as connecting rod reducer and again before and after the main bearing assembly gap is too small, smooth oil is too dirty and long-term use of smooth oil change will increase the moving parts of the friction and wear and tear, or at the same time as the cylinder wear serious fluctuation pressure gas, will incur crankcase heat, high oil temperature, smooth the oil viscosity is reduced, so as to form a vicious cycle of smooth condition and form a smooth system. So for the smooth system fault analysis should be comprehensive, which in addition to smooth the system itself also should from the refrigerator to check the running status, analysis and discrimination, such as the presence of abnormal vibration, noise, heat, leakage, etc. Smooth water chiller water chiller system is one of the most common problem: oil pump pressure, pressure regulating failure and thrash pressure gauge pointer. Its main reason is: 1, the system of serious leakage. 2, the pump work for a long time, the wear of the pump is serious, internal leakage is too big, volume effect is decreased obviously. 3, crankcase medium oil temperature is too low, frozen stick through the large, smooth oil pump inlet filter mesh too close, the filter is infarction, as well as the oil level is too low, the oil pump oil absorption, empty form suction phenomenon. 4, the pressure regulating valve core is stuck in the open position or pressure regulating valve spring failure. From the following several aspects can certainly can smooth water chiller system normal: 1, in the crankcase oil level should be enough, and should be stable for a long time. 2, in the crankcase oil temperature should be insisted on 10 - The most suitable working temperature 65 ℃, 35 - 55℃。 3, oil filter, filter should not be infarction, with the differential transmission precision filter should have infarction transmission is indicated. 4, hydraulic table specified stability, indicating pressure on the piston or refrigerator should be higher than suction pressure of 0. 05 - 0. 3 mpa, screw freezer should be higher than the condensing pressure 0. 2 - 0. 3MPa。 In smooth water chiller system maintenance should pay attention to the following points: 1, pay attention to check in daily check oil level, oil temperature, oil pressure can be normal. 2, according to the rules of frozen smooth oil index of oil change regularly check oil, change or supplement the new oil filter. 3, should pay attention to when, overhaul in check and adjustment of pump end clearance, should be in pump when necessary. The end of the pump clearance depending on the size specification is about 0. 03 - 0. 8 mm, detailed numerical please see about the pump assembly technology request and the factory rules. 4, regular change or cleaning filter, pipeline and crankcase. Smooth water chiller system maintenance, strong technical request of mainly touches of tightening machine performance, initiative maintenance by professionals to stop the operation, prevent to produce don't want to loss.
