Screw air compressor sometimes work for a long time, resulting in the phenomenon of high temperature, especially in the summer, when the temperature is too high fault often occurs, then the air compressor temperature is too high is how to return a responsibility?
1. Poor environmental ventilation and heat dissipation
there are three main situations in which the surrounding environment of the air compressor affects heat dissipation: first, it is too close to wall obstacles; Second, there are other heat sources near the air compressor; third, the front door and side door of the air compressor are open during operation, and the fan cannot form strong airflow.
2. The radiator is blocked
when there is a lot of dust in the environment around the air compressor, long-term operation will cause a layer of dust or sludge to adhere to the outer surface of the radiator, and its internal copper pipe will be easily blocked due to the accumulation of grease, thus affecting the heat dissipation effect.
3. The oil filter is too dirty
the machine has three oil filters side by side. When it is too dirty, the resistance oil cannot enter the compressor according to the normal flow rate, and the compressor will heat up rapidly due to insufficient cooling and lubricating oil. When the inlet and outlet oil pressure difference exceeds 0.18MPa, the filter element needs to be replaced.
4. The oil level of the cooling oil is too low
when the cold machine inspection, the oil level is lower than the lower end of the inspection tube should be immediately replenished.
5. Low oil grade or poor oil quality
the machine uses the manufacturer's special compressor oil. When using other low-grade or inferior oils, the viscosity and specific heat will not reach the standard and the temperature will be too high.
6. The fan belt is broken or loose
when the tape breaks, the air compressor will automatically stop when it runs for about 5 minutes due to excessive temperature. If the tape is too loose, it will slip, which will reduce the fan speed and affect the heat dissipation. At this time, the tightness of the fan tape should be replaced or adjusted.
7. Failure of oil cut-off valve
there is an oil cut-off valve between the oil filter and the compressor. When the oil cut-off valve cannot be opened, the temperature of the compressor rises rapidly after starting due to no oil lubrication and cooling, and it will automatically stop in about 1min. Remove the temperature plug at the discharge end of the compressor host, and you will find that the plug is dry and oil-free, and there will be smoke floating out of the hole. Open the manhole at the bottom of the air compressor, remove the oil cut-off valve, and gently move the valve stem with your fingers to see if it can be pushed back and forth and reset easily. If it is difficult to move or return, the oil cut-off valve needs to be further disassembled. If the valve stem or valve hole has grease, it needs to be polished with fine sandpaper until it can slide easily. If the spring is broken or there is foreign matter stuck, the movement of the valve stem will also be affected. At this time, the spring or spring and spring seat need to be replaced or cleaned.
8. The filter element of oil and gas separator is too dirty
when it is too dirty, the oil will affect the circulation due to excessive resistance, causing overheating and shutdown. This situation is judged from the pressure difference before and after loading. When the pressure difference between the two ends is 3 times of that at the beginning of the startup or the maximum pressure difference reaches 0.1MPa, it should be cleaned or replaced.
This reason is more, we first one to rule out, first of all, we have to understand how much your air compressor flow, and your gas is proportional to, if the screw air compressor itself flow is not up to, what do you think is the problem,
For the screw air compressor should be how to select, you first need to know the work flow of the screw air compressor, and then determine how to select. Generally speaking, there are three steps:(1) first determine the working pressure;(2) then set the corresponding volume flow;(3) finally, the power supply capacity. Selection of working pressure (exhaust pressure):
Product features: intelligent start-stop detection of ambient temperature, prevention of high temperature fault detection caused by high ambient temperature post-processing equipment end pressure, effectively prevent high pressure difference of compressed air, waste of electric energy detection of motor temperature, protect the core technology of motor
View detailsA good brand of domestic oil-free air compressor, Shanghai granklin group provides you with a quotation for oil-free screw air compressor, which is a high-quality product and brand in the domestic air compressor industry. we sincerely invite peers who want to act as agents for oil-free air compressor and win-win cooperation.
View detailsWater lubricated screw air compressor host, water vapor cylinder, water filter and air filter, intake valve, cold dryer, air storage tank, etc. are integrated into one, forming an integrated air compressor system. The built-in three filters are easy to maintain, and there is no pipeline loss inside. It takes up very little space and is the key first step in forming a small lightweight air compressor; at the same time, it also provides
Basically, according to each air compressor factory has a standard for its own air compressor, it is best to look at the instructions! Some manufacturers also have 2000 hours of oil and 4000 hours of oil. Some are calculated from the sale to the customer, the initial insurance time and the later period.
Generally, there are relevant installation manuals for the installation of mechanical equipment. The same is true for silent oil-free air compressors. Whether the environmental quality is good or not, the silent oil-free air compressors need to pay attention to the installation environment and whether it affects the installation effect. need in sufficient light
Domestic oil-free air compressor manufacturers, choose "Shanghai Granklin Group", a group company specializing in the production of "water-lubricated air compressors. Years of "oil-free air compressor" production, has accumulated rich experience and profound technology, in the country has a wealth of cases. There are pharmaceutical factory, food factory, electronics factory, process gas factory (such as argon), laboratory preparation, marine air compressor, bottle blowing, beverage, wine, hospital and so on.
When we have prepared the preliminary preparations, the oil-free air compressor can be started according to the following procedures: 1. The unit is turned on, check whether the rotor and the stator have abnormal phenomena such as friction and collision, and confirm that the rotor is turned on flexibly; 2. Slowly lift the starter handwheel,
The advantages of oil-free air compressor: oil-free air compressor has low noise, which solves noise pollution, and oil-free air compressor solves the phenomenon of compressed gas oil and water. The machine itself contains a water outlet, which can discharge the water in the gas tank. Increased service life. At the same time, the oil-free air compressor does not need lubricating oil, which reduces the cost of purchasing lubricating oil.
