Several Common High Temperature Failures And Investigations Of Screw Air Compressors

High temperature failures occur after long -term use. It is inevitable that the manufacturer and engineering staff of Zhongtian Boris screw air compressor have summarized several common high temperature faults and investigations of screw air compressors. Help in use.

1. Bad temperature sensor, or the temperature sensor wiring error.
2. Check whether the temperature sensor has a disconnected fault in the middle. Under the condition (28 ° C), the volume resistance value of the Ohm meter (28 ° C) indicates that it is broken if it is too large or too small.

(1) High environmental temperature: For example, the maximum environmental temperature of an air compressor design of a company is 40 ° C. If the surrounding environment is high, the exhaust temperature will occur. At the same time, pay attention to whether the chassis air inlet is blocked, or whether the thermal wind can be discharged smoothly or the thermal air is returned to the air inlet of the chassis.

(2) Whether the oil level of the air pressure is too low, and the liquid level is too low, resulting in the oil and gas barrel owner's main oil pipe cannot be returned to the oil. This is a problem if the temperature decreases after adding some air pressure engine oil.

(3) Whether the fan is reversed or the air radiator air duct is seriously blocked. The blocking of the radiator air duct is the most often problematic. When blowing the radiator, it must be blowing through the air duct. You can see the other side.

(4) Whether the oil filter has not been replaced for a long time, resulting in blocking, which affects the reduction of screw oil into the head of the machine and leads to high temperature. The solution replace the oil filter. If there is no oil filter at the scene, the old oil filtration can be verified by a few short hole tests inside the old oil filter.

(5) Is the entire pipeline and components on the main oil jet port of the oil and gas barrel from the oil gas pipe to the head of the machine? For example, the oil duct is the most easily blocked after the coke. The main method can only be removed and checked one by one.
