Jiaxing bearing | how to chiller maintenance lubrication system

There is rotational, have HRB bearing ( ) Jiaxing chiller lubricating system for bearing | how to maintenance of jiaxing bearing group sales co. , LTD. ( The company) Is bearing group co. , LTD. Established in jiaxing spot sales window, specializing in HRB brand bearings, facing the whole country, the existing stock 50 million yuan, covers the whole bearing, have very strong spot supply, is the group's retail sales center. Chiller operating system, pay close attention to more is refrigerator, frozen water cycle system refrigerant cycle system and electric control system of three parts, and lubrication system is often overlooked. Little imagine, this system for water chillers, is also very important. Cold water machine lubrication fault are not of the lubrication system of the problems of its own, but also will lead to system failure. Improper selection, processing and assembling of piston ring structure such as cylinder oil, can cause a lot of abnormal and the shaft seal leakage will bring down the crankcase CPC surface significantly, leading to the oil pump suction empty phenomenon; Again, such as connecting rod reducer and main bearing assembly gap is too small, before and after the oil is too dirty and the long-term use of lubricating oil metamorphism will increase the moving parts of the friction and wear and tear, or at the same time due to the cylinder wear appear high and low pressure gas, will lead to the crankcase fever, high oil temperature, oil viscosity is reduced, thus forming a vicious cycle of lubrication condition and lubrication system failure. So the failure analysis of the lubrication system should be comprehensive, which in addition to the problems of its own lubrication system also should begin from the refrigerator running status of inspection, analysis, and judgment, such as the presence of abnormal vibration, noise, heat, leakage, etc. Cold water chiller unit lubrication system is the most common failure: oil pump pressure, pressure regulating failure and violent oscillation pressure gauge pointer. The main reason is: 1, system 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, freezing lubricating oil viscosity is too large, pump imported oil filter mesh too close, the filter is blocked, and the oil level is too low, the oil pump oil absorption is difficult, empty absorption phenomenon. 4, the pressure regulating valve core is stuck in the open position or pressure regulating valve spring failure. Water chiller can be determined from the following several aspects lubrication system is normal: 1, in the crankcase oil level should be enough, and should be stable for a long time. 2, crankcase oil temperature should be kept in 10 - Between 65 ℃ and optimum working temperature of 35 - 55℃。 3, oil filter, the filter should not be blocked, with the differential transmission of fine oil filter should have congestion dispatch instructions. 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。 On maintenance of water chiller lubrication system should pay attention to the following points: 1, observed in daily check the oil level, oil temperature, oil pressure is normal. 2, according to provisions of freezing lubricating oil regularly check oil change indexes of oil, replace or supplement the new oil filter. 3, should be paid 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, please see the amount of pump assembly technical requirements and the factory regulations. 4, regular replacement or cleaning filter, pipeline and crankcase. Chiller lubrication system maintenance technical requirements is stronger, mainly involving the performance of the compressor, suggested by professionals, maintenance to avoid unnecessary loss.
