Earthquake analytical methods compressor
Foreword
Compressors in the field of applications, its compressor vibration and noise have been all users and producers use a heart disease , equipment manufacturers also cast a lot of energy and resources on this project , to overcome these problems , but the effect not very good, new equipment to use when the plant started , the above problem is not much impact , vibration and noise are acceptable for customers , but with the accumulation of machine uptime , the noise also increases with , ( noise from vibration ) , increased failure rate of the machine , whereby the service life of the machine while the machine is due to the influence of vibration . Avoid equipment failure rates rise , it is necessary to reduce the noise and vibration of the machine.
Installation of equipment , not just connecting pipes and power , the most important is the foundation ( ground-based ) , such as practicing martial arts , not just started practicing martial arts, but Zhan Zhuang , and many people tend to stand Zhan Zhuang sin , and Zhan Zhuang give up learning . Zhan Zhuang finally learn who did not participate in the foundation of martial arts practiced Zhan Zhuang people simply not as good as the foundation of a good , showing how important the foundation !
Some equipment in some small manufacturers have joined the damping device on the device , the equipment required for the construction site of the much lower . So was that the device does not require foundation requirements , that can be connected with the use of the pipeline and power . This is also true for some plants to provide a great convenience, but in the actual operation of the device , regardless of how good design of the equipment , how excellent , is only part of the equipment , the installation will reasonably minimize the machine's fault . ( Now the country has introduced a compressor room design standards, but there is not much talk on the base )
About damping devices generally have the following : The most commonly used is rubber shock absorption. In addition to damping rubber pad , there are springs, sand and ground isolation .
Compressor starts , poor , boot automatically shut down after a few seconds
1, check the automatic air switch is off , the voltage is normal, should be excluded ;
2 , whether the extent of the intake valve to close properly , check , need to re- adjust or replace ;
3, check the Y-△ startup contactors and motor -phase is normal.
Difficulty in starting the compressor is operating normally , shut down after
1, using the right grade of oil , after the oil change should be cleaned thoroughly ;
2 , oil stick , coke , oil change should be thoroughly after cleaning ;
3, seal serious leak , remove the replacement ;
4 , unloading valve changes its original position , re- adjust the position .
Compressor does not start
1, check whether the control voltage. If not, will have to check the fuse is intact ;
2, check the time and continued to control electrical appliances continued normally.
No gas compressor
1, check whether the motion control cylinder , check valve for mechanical failure ;
2 , check whether the load solenoid valve coil suction ;
3 , one investigation of the circuit where the solenoid valve .
Large compressor fuel consumption
A suspected oil content of water discharged from the cold trap is large , such as large , you should check the leak and the crew be excluded ;
2, check the compressor oil level is high, as high oil level should be reduced ;
3 , check the pressure valve opening pressure is normal, necessary, inspection, replacement of the valve ;
4, check the return pipe is clogged , clean or replace if necessary return pipe ;
5 , check the oil separator is invalid , when necessary, replace the oil separator filters .
Exhaust temperature is too high
1, check the exhaust pressure exceeds the requirements , such as over , should be adjusted to shoot air pressure requirements ;
2 , check the oil is clean and the oil level is normal, necessary, top up or replace oil ;
3 , check the fan motor speed is normal, the exhaust port is blocked ;
4, check the oil cooler, after cooler appearance is clean , clean the outer surface of the cooler when necessary ;
5 , check the ambient air intake and exhaust of the unit whether the impact , if any , should be excluded from external factors , to ensure normal ventilation units ;
6 , check the temperature control valve is damaged ; checking the solenoid valve coil and solenoid valve diaphragm is damaged , repair or replace if necessary ;
7 , check the oil separator filter is clogged or the resistance is too large , and if so, replace the oil filter element .
Exhaust pressure is too high
A check valve mechanism for mechanical failure, if any , should be excluded from the fault ;
2, the load solenoid valve leaks , such as leakage , should troubleshooting, if necessary, replace the solenoid valve ;
3, check and adjust the pressure switch on the limit, replace the pressure switch if necessary.
