Generally, the first maintenance of a new machine is 500 hours, and the second maintenance is about 2000 hours, which can be determined by the specific use environment. Time is not fixed, but if the environment is too bad, it is best to maintain it in advance. If the environment is good, it can be slightly delayed.
There are two different types of air compressors, which are divided into oil lubrication and oil-free lubrication. Among them, oil-lubricated air compressors are often used in industrial equipment, such as auto shops, for long-term operation. Oil lubrication prevents excessive machine temperature. For a long time, the oil of the air compressor has become thick and black, making it less efficient as a lubricant and reducing lubrication performance.
If it is not treated and replaced in time, the waste oil may cause the air compressor to overheat and damage. Generally, when you buy air compressor oil, air compressor dealers or manufacturers will recommend that you protect the air compressor machine is to regularly maintain and replace the air compressor oil.
How to judge whether your air compressor needs to change the oil:
1. The date of the last change of air compressor oil;
2. Find the observation window or dipstick to measure the amount of oil in the air compressor;
3. Observe the amount of oil in the air compressor through the sight glass, or take out the dipstick.
4. Compare the amount of oil seen on the sight glass or dipstick with the recommended volume in the air compressor manual. If the machine contains less oil, you need to add air compressor oil.
In fact, the simple thing is to estimate the number of hours since the last oil change, for example, the screw air compressor has been turned on and running. If it runs for more than 300 hours, new oil is needed. If the air compressor is not operated frequently and the specific time since the last maintenance interval is not known, the oil should be changed at least once a year.
The air volume calculation of the ship air compressor should be combined with the specific purpose, equipment parameters and industry standards. The following are the key steps and key points: the basic formula of 1. air volume calculation The basic formula of air volume (Q) of the air compressor is: Q = V / T Q: air flow (unit: m & sup3;/min or L/s) V:
The calculation of the amount of compressed air required by the instrument system requires comprehensive consideration of factors such as instrument type, quantity, working mode, system loss and standby requirements. The following are detailed calculation steps and examples: 1. calculation steps 1. Determine the instrument type and air consumption of different instruments.
In view of the question of "is the safety valve on the air compressor strongly inspected", it can be answered from the following aspects: legal basis: according to the "special equipment safety supervision regulations", some special equipment needs compulsory testing. However
The storage pressure level of industrial gases is not generalized, but is determined according to the specific gas type, use requirements and safety regulations. In general, industrial gases can exist in the form of high pressure, medium pressure or even low pressure, depending on the nature of the gas.
The specific power is the "power consumption report card" of the air compressor, the smaller the better. Because the water-lubricated air compressor has low water resistance, no aging, and good heat dissipation, it is naturally easy to get a smaller specific power, which saves electricity and produces clean gas. It is a "smart and clean" choice.
Generally, the air pressure in a factory is determined according to different application requirements and equipment specifications, so there is no fixed value. But here are some common factory air pressure ranges and related information: Normal pressure ranges for industrial compressed air
Q: the difference between oil injection and micro oil air compressor answer: oil injection air compressor oil content comparison micro oil air compressor oil content will be more. The oil-injected air compressor did not carry out more detailed treatment of the exhaust gas, and the micro-oil air compressor handled it relatively better, but in essence it was changed.
Oil-free air compressors do not require the use of oil during their operation. The oil-free air compressor uses oil-free lubrication technology, usually through water lubrication, dry operation or other oil-free lubrication methods to work to ensure that the gas is not contaminated by oil during the compression process.

For the question of whether the 2 cubic compressed air storage tank needs to be reported, the answer depends on the design pressure of the storage tank and other relevant factors. If the design pressure of the gas storage tank is greater than 1kg (or 0.1 MPa), it needs to be reported according to relevant regulations.
The variable frequency screw machine can work continuously in theory. The screw air compressor can run for 24 hours. When the air pressure is not enough, it will automatically load, when the air pressure reaches the preset value, it will automatically unload, and when the no-load time exceeds the rated time, it will automatically stop, realizing no one for 24 hours.
