Due to the uneven reciprocating motion, it wears out quickly and needs to be replaced frequently. The cylinder needs to be removed and repaired within a month, and many sealing rings need to be replaced.
Due to the uneven reciprocating motion, it wears out quickly and needs to be replaced frequently. The cylinder needs to be removed and repaired within a month, and many sealing rings need to be replaced. There are dozens of parts such as cylinder liner springs that need to be replaced. Pistons, piston rings, valve valve parts, crankshaft bearings, etc. run continuously. Due to the large number of parts, especially vulnerable parts, the failure rate is very high, and several maintenance personnel are usually required.
After the pressure reaches the desired operating pressure, the conventional control method determines that the pressure will continue to rise until the unloading pressure. During the pressurization process, more heat and noise will definitely be generated, resulting in electrical energy loss. On the other hand, before the high-pressure gas enters the pneumatic components, its pressure needs to be reduced by the pressure reducing valve, which is also energy-consuming.
The main reasons for the high temperature can be divided into the following: oil filter blockage, temperature control valve spool jam, oil cooler internal or external is seriously polluted. Oil filter installed in the temperature control valve and oil cooler upstream is an effective way to avoid oil failure, but many brands of screw compressor oil filter only to protect the head.
The pressure maintenance valve is located at the outlet of the oil fine separator above the oil and gas barrel, and the opening pressure is set at about 0.45MPa. The function of the pressure maintenance valve is: to establish the circulation pressure required by the lubricating oil first during starting to ensure the lubrication of the body; When the pressure exceeds 0.45MPa, the air flow rate flowing through the fine oil separator can be reduced. In addition to ensuring the fine oil separation effect, the fine oil separator can be protected from damage due to too large pressure difference.
