Are air compressor accessories universal?
There are often some users of screw air compressors asking whether the accessories can be used universally. In fact, Compressor accessories manufacturer can tell everyone responsibly that they cannot be used universally. It is recommended not to use it in the case of the model. The high-pressure machine involves high pressure, and accidents will occur if the pressure level is different.

The assembly method of air compressor accessories
Compressor accessories manufacturer tells you to remove the cap screws on the elastic element of the air compressor coupling and remove the elastic element; loosen all the mounting screws of the taper sleeve, take out one or two screws, and lubricate the threads with lubricating oil and the tip of the countersunk screw, and then insert the screw into the ejection hole of the taper sleeve. Alternately tighten the screws until the taper loosens in the compressor coupling bushing and moves freely on the shaft. Remove the bushing and tapered sleeve from the shaft.
Clean the inside and outside of the tapered sleeve and the protective layer on the taper hole of the sleeve; after ensuring that the matching tapered surface is completely free of oil and dirt, insert the tapered sleeve into the sleeve.
Lubricate the threads on the bushing and the tip and threads of the screw with a little oil, and gently place the screw into the threaded hole in the bushing.

Clean the main shaft and retaining ring, insert the retaining ring into the shaft, and level the bearing rings, install the flat key. First, install a pair of shaft sleeves and taper sleeve on the shaft as a whole, press the taper sleeve on the main shaft and turn the ring end bolt to the right, so that the retaining ring, taper sleeve, and bearing ring of the air compressor coupling are pressed against each other without gaps tight. Warm tips for compressor accessories manufacturers: first tighten the taper sleeve on the shaft of the air compressor coupling, and then gently pull the taper sleeve onto the taper sleeve.

Alternately and gradually tighten the screws using the Allen key until the specified torque is reached. Install the other shaft sleeve and taper sleeve on the motor shaft, keep it loose for adjustment; put half of the elastic element around the shaft sleeve of the air compressor coupling, and fix it with self-locking cap screws. The elastic element determines the position of the shaft sleeve at the motor end, and then gradually fixes the shaft sleeve at the motor end. Install the other half of the flex member and tighten all cap screws to the specified torque.
Assembly method and installation skills of the air compressor cylinder

Generally, cylinders with lower pressure are made of cast iron. The high-pressure cylinder is made of cast steel with replaceable bushings.
When installing the cylinder, it is mainly to ensure the durability of the operation of the cylinder and the piston, in other words, to make the centerline of the cylinder and the centerline of the machine base completely coincide to form a straight line perpendicular to the main shaft.

Assembly method and installation skills of the air compressor cylinder

The installation method of the air compressor cylinder is as follows: remove the corrosion protection layer on the flange surface of the machine base and the connecting end surface of the cylinder, and wipe it clean. Prepare a complete set of connecting bolts and nuts.

Hang two chain gourds with a lifting capacity of 1 ton each on the lifting hook of a crane with a lifting capacity of up to 5 tons, so that the water in the cylinder can be adjusted and set on the inside of the valve cover at both ends of the cylinder during the connection process. A sling, and put the sling on the lifting hook of the chain hoist to lift the cylinder.

Then remove the steel wire on the cable frame, but do not move the position of the cable frame. Slowly hoist the lifted filter to the flange surface at the front end of the machine base, and align the connecting bolts on the cylinder with the corresponding screw holes on the flange; if there is a slight error in the position, you can use the chain hoist to adjust it.

After the position is aligned, insert the connecting bolts into the holes of the flange, take the connecting nuts from the inside of the machine base, and preliminarily tighten them. When tightening the nuts, the force of each nut must be the same. At this time, the lifting device can be removed.

Set up a steel wire leading to the cylinder and the machine base on the small wheel of the cable stand again, and correct them according to the machine base so that they are on the centerline position of the machine base. Then adjust the cylinder according to this line so that the center line of the cylinder coincides with this line.

When calibrating the cylinder to measure the position of the steel wire, can be carried out on sections I-I of the front end of the cylinder and sections II-II of the outer casing of the stuffing box.

If possible, it can also be measured on the rear end section of the gas storage tank, and the measuring point should be 20-30 mm away from the ends of the cylinder.

When measuring, be sure to calculate the error of the wire deflection. If the center line of the cylinder is not correct, it can be adjusted by adjusting the tightness of the connecting bolt cap of the machine base, adding a thin pad between the flange surface and the connecting end face of the cylinder, or filing the port where the machine base contacts the cylinder.

The allowable error of the center of the cylinder must be within 0.10 mm/m. While measuring the fine steel wire, use a level ruler to check the levelness of the cylinder on the lower arc mirror in the cylinder. The allowable deviation of cylinder levelness is within 0.10 mm/m. The installation method of the high-pressure cylinder is the same as that of the low-pressure cylinder.

How to use air compressor accessories
Pressure regulator adjustment steps: Generally, the unloading pressure of the air compressor is adjusted with the adjusting bolt. Turn the bolt clockwise to increase the unloading pressure, otherwise, the unloading pressure will decrease; then is the adjustment of the differential pressure value, which is adjusted by the differential knob at the bottom. Make adjustments, turn counterclockwise, the pressure difference value of the air compressor will decrease, and do the opposite operation again;
Air filter: The air compressor will inhale the dust in the air during operation, and then it will be blocked in the filter. Usually, after 1000 hours of operation or one year, the filter element needs to be replaced to prevent clogging. In an environment with harsh working conditions Next, the replacement cycle should be shortened. The compressor accessories manufacturer tells you that if it is the first maintenance, it will be used between 300-500 hours;
Condenser: There is a requirement for the inside of the condenser tube of the air compressor, and the appearance must be kept clean, otherwise the condensation effect will be reduced, and it must be replaced regularly if necessary;
Gas storage tank/oil-gas separator: Both are manufactured according to pressure vessel standards, and cannot be modified at will during use;
Safety valve: It is installed on the gas storage tank/oil-gas separator. It should be inspected at least once a year. The operation should be handled by a professional person. Check the safety valve to ensure smooth operation.

Maintenance
1. Check the oil level, exhaust temperature, and exhaust pressure daily, and check for abnormal sounds;
2. Open the drain valve of the separator every week to discharge the condensed water, check whether there is any leakage everywhere, check the safety valve, and check the wear of the belt (visual inspection);
3. Regularly check the air intake control valve, minimum pressure valve, electric control box connection terminal, safety valve, and cooling fan;
4. Regularly clean and clean the cooler, and test the reliability of the safety valve;
5. The manufacturer of compressor accessories tells you that the oil filter element, oil separator element, intake filter element, and lubricating oil need to be replaced regularly.
