A full range of care and maintenance of screw type air compressor

Proper maintenance on the service life of the air compressor and operating reliability plays an important role to the United states. In modern industry, screw air compressorwith its advanced nature, reliability, energy conservation concern. How tomaintenance and maintenance of screw air compressor, small make up is simple to do the following analysis.

First we have a look the maintenance of intake air filter: air filter is to filter out thecorrect air dust and dirt components, filtered clean air into the compression chambercompression screw rotor. Because the screw compressor internal clearance is allowed only within 1 5u of the particle size of space. If the air filter blocked or damaged,particulate mass greater than 1 5u into the screw machine, not only greatly shorten the service life of lubricating oil filter, oil separator, will lead to massive particlesdirectly into the bearing cavity, accelerated bearing wear increased so that the rotorclearance, the compression efficiency. Di, even as the rotor clearance is notreasonable while the mutual impact friction, shorten the service life of the rotor. Air filter best every week maintenance time, R-9 gland nut, remove the filter element, with 0.2 0.4Mpa of compressed air, from the inner cavity of the filter element to purge, with a clean cloth to filter on the inner wall of the housing. Clean. In the back of air filter.Attention should be paid to seal air filter in front of the shell and the inner end facecontact close to.

Air filter to normal in 1000 and replaced every 1500 hours, the environment particularly bad situations and different seasons, such as the northern winter andspring and autumn wind season, every 500 hours to replace an air filter.

Clean or replace the air filter, components must be installed according to originalassembly form and order, to prevent foreign matter fall into eight valves.

I need to check the intake of telescopic pipe is damaged, suction flat deformation,expansion joint and the air filter inlet valve connector with no loosening, leakage. Such as abnormal shall timely repair or replacement.

Maintenance of lubricating oil filter replacement: new machines for the first time after 500 hours of operation should be the replacement of oil filter, oil filter with special spanner anti spin off, the new filter element is installed to the best plus screw oil return oil filter, filter seal seat with both hands twist, forced to tighten.

And the best in the replacement of the new filter using 1500 - 2000 hours, change the oil at best and replace the oil filter, in the harsh environment should shorten thereplacement cycle.

Note: it is strictly prohibited to use extended oil filter, or due to severe clogging of the filter element, the pressure difference exceeds the carrying capacity of bypass valve,a bypass valve automatically opens, a large number of stolen goods, particles can bedirectly with the oil into the screw within the host, causing serious consequences.

Maintenance oil separator replacement: oil separator is the screw oil components andcompressed air separation, normal operation, oil separator service life in 3000 hours,but the boudoir of lubricating oil quality and air filtration Sui degree has a great effecton the life of. Visible in the harsh environment must shorten the air filter maintenancecycle, or even consider adding front air filter. Oil separator must be replaced in thepressure difference before and after the expiration or over 0.12Mpa, otherwise it will cause electric vertical load, oil separator damaged run oil.

Maintenance and replacement of screw oil: screw oil depend on the WAN performance by the screw machine has a decisive effect, good oil has antioxidant stability, rapid,good separation bubble, high viscosity, good corrosion resistance, therefore, the user must use pure special screw oil. The running in period of new machine 500 hoursafter first replacement screw oil, after every 2000 hours of operation to replace ascrew oil. Oil change at best and replacement of oil filter. In the harsh environment of the places to shorten the replacement cycle.

Screw oil change: the first to start the air compressor to run for 5 minutes, the temperature of the oil to 50 , the viscosity of the oil drop; stop running, when the fuel tank holds 0.1 Mpa pressure, oil discharge valve is opened at the bottom of the tank, put a bucket connected; (oil discharge valve should be opened, in order to avoid the pressure with temperature and lubrication oil spill wounding slowly) Such as;lubricating oil drops off after discharging oil valve; unscrew the oil filter, the oil pipelinein the dump, a new oil filter change; opening force Ting by export blocked, injected bythe oil level in the oil's, the scale line range, tighten the gas export blocked, check no leakage phenomenon; the lubricating oil must be inspected regularly in the use process, found that the oil level line is too low to be new oil supplement timely,moistening irrigation by using must often discharge of condensed water, generalpump weekly, 2 - 3 days in a high temperature discharge. Shut down for more than 4 hours, no pressure in the fuel tank under the condition of open the oil valve,discharge condensate water, see the quick closing valves oil outflow; lubricating oil is strictly prohibited mixed use different brands, no cases of extended use lubricating oilor lubricating oil, quality decline, lubricating performance, burning point drop,extremely easy to cause the high temperature condition, cause the spontaneous combustion of oil.

Cooler maintenance: cooler effect, directly affect the operating temperature of the air compressor. The structure of plate fin and easy to gather dust, so the coolermaintenance needs every shift with 0.4Mpa or dry compressed air from top to bottomblowing. Blowing dust particles after the pilot, the wind cover clean, prevent dirt again by the fan blowing cooler jam, cause the machine to high temperature. The machine ifused in harsh environment, wall surface is full of oil, it is necessary to use carboncleaner to clean water.

Reminder.
