which items need to be inspected in the daily inspection of air compressors?

how are you? What kind of project inspection do you do? Full efficiency or type test? Screw machine, belt conveyor, or direct action type?

for general users, some compressor maintenance suggestions are provided for users to refer to.

① Every week:

a. Check the unit for abnormal sound and leakage;

b check whether the meter reading is correct;

C. check whether the temperature display is normal.

② Every month:

a. Check whether there is rust or looseness in the machine. If there is rust, remove rust, oil or paint, and tighten the looseness;

B. drain condensed water.

③ Every three months:

a. Clean the dust on the outer surface of the cooler, fan cover and blades;

b. fill the motor bearing with lubricating oil;

C. check the hose for aging and cracking;

D. check the electrical components and clean the electric cabinet. How to check the sheets? What projects need to be inspected?

Detailed inspection items: 1. Fabric quality and appearance: no breakage, pinholes, color stains or stains are allowed; Linear defects and strip defects are allowed to be slightly 1 points/surface (referring to the thick diameter not more than 3 times of yarn count); Poor printing is allowed to have slight overlap, staining, bleeding and missing printing, which will not affect the appearance.

(The size of large products is 111cm and above, and the size of small products is below 111cm) 3. Quilting quality: the trajectory is smooth and flat, and there is no wrinkle; At the beginning and end of quilting, the needle must be returned, the needle sleeve should be straight, and the wireless head should be used; The stitches are neat and even. 4, sewing needle quality sewing needle: no jump needle, floating needle, missing needle, off-line, off-center needle does not exceed 1.2cm/21cm quilting needle: jump needle, floating needle, missing needle, off-line each place does not exceed 1cm, not allowed to exceed 5 places/piece 5, embroidery quality All kinds of stitches are flat, neat, even, live and clean. Flat: the needle code is flat, and the embroidered surface is flat; Qi: the pattern changes naturally, and the embroidered edge contour is neat; Uniform: the needle code is uniform and thin, fine and appropriate; Live: the needle is smooth, the color is natural and full of three-dimensional sense; Clean: The embroidered surface is clean and free from contamination. Embroidered flat clothes, no obvious omission of embroidery, accurate color of spray embroidery, natural transition, no overlap and good position. 6. Sewing quality (1) The sewing trajectory should be even, straight and firm, and the hemming and flat sewing clothes should be straight, uniform in width and no hair exposed. (2) The sewing needle should be aligned, and the sewing needle must be returned to the edge by 1cm. (Note: 4-5 stitches are returned) (3) stitch density: 12-15 stitches /3cm for plain sewing and 11-12 stitches /1cm for overlock sewing. 7. Identification (1) The content of the trademark must be consistent with the product under inspection; (2) The trademark of the durable washing water mark must conform to three national items: specification, fiber composition and washing instructions. 8. The deviation of specifications and dimensions is within -2% according to the process design. If you have any other questions, you can check the QC encyclopedia of the database and other related contents of the information.

how to make the daily inspection record?

You asked about the inspection record form. First of all, I think your company's quality or technical department must have an inspection record form in a unified format. (Including the inspection frequency of inspection items, etc.) You can follow the specified requirements. If you want to make statistics on a situation of daily inspection, you can just make a checklist for recording. The contents include: unit/date/product name /ok product number /NR product number /NG.

1. Appearance inspection method: visual inspection (when viewed from a place with a visual distance of 25cm and a 45-degree angle and strong light). Inspection standard: incoming transformers should have the material type number, and there are no serious defects such as oxidation, foreign bodies and broken wires on the transformer feet; incoming transformers have no material type, but slight defects such as oxidation, foreign bodies and broken wires on the feet. However, it can be removed. 2. Size inspection method: use digital display calipers to test the flying wire length, wire diameter, magnetic core height of the transformer and the length, width and height inspection standards of the transformer: all dimensions should be consistent with the specifications of this model. Serious defects: exceeding the maximum or minimum size range in the specifications. 3. high voltage test inspection method: short-circuit the primary and secondary stages of the transformer respectively. Then add 4251VAC 51/61Hz sine wave voltage to the two stages and test with 5mA current for 5 seconds. Inspection standard: no arcing, serious defects of alarm: arcing, alarm. 4. Efficiency test inspection method: put the transformer on the corresponding test rack for testing inspection standard: the output voltage of each secondary of the transformer should be consistent with the specification requirements. Serious defects: the output voltage of each secondary of the transformer is inconsistent with the specification requirements. 5. Installation test inspection method: the transformer and the corresponding PCB board are tested for plug-in inspection standard: the foot distance and flying wire length of the transformer are consistent with the corresponding hole distance on the PCB board. Plug-in is easy to have serious defects: the foot distance and flying wire length of the transformer are too large and too small, and the plug-in is difficult. 6. Quotation test and inspection method: Test the number of turns of transformers at all levels with automatic electronic component analyzer. Inspection standard: The number of turns, inductance, leakage inductance, phase and Q value of windings at all levels of the transformer are consistent with the requirements of the specification. Serious defects: Test the number of turns, inductance and leakage inductance of transformers at all levels. 7. Inconsistency of phase and Q value with the requirements of the specification. Inspection method of process test: 2PCS is taken from the sampling transformer for disassembly inspection standard: the number of high-temperature adhesive layers, the number of turns of the coil, the wire diameter, the material, the winding direction and the length of the coil are consistent with the requirements of the specification. Serious defects: the number of high-temperature adhesive layers, the number of turns of the coil, the wire diameter, the material, the winding direction and the length of the coil are inconsistent with the requirements of the specification.

Dangerous places need to be inspected at least twice a month

Crowded places need to be inspected every day

Do you need to inspect the oil-gas separator in the air compressor once a month in general places?

Inspection of oil-gas separator in air compressor:

If it is marked as "simple pressure vessel", it is unnecessary to carry out compulsory inspection on the body. But there are service life requirements. For details, please refer to Safety Technical Supervision Regulations for Simple Pressure Vessels.

if not specified, it belongs to a special pressure vessel and needs to be inspected.

Brief introduction of oil-gas separator:

Oil-gas separator is a device for separating crude oil produced by oil wells from associated natural gas. The oil-gas separator is placed between the submersible centrifugal pump and the protector to separate the free gas in the well fluid from the well fluid, the liquid is sent to the submersible centrifugal pump, and the gas is released to the annular space of the tubing and casing. What project does hair loss need to be tested?

Hair loss can be caused by many conditions, including heart, liver, spleen, lungs and kidneys. Tell your doctor what you feel unwell and you will be arranged to have a test. * Sufalin * can prevent and reduce hair loss. What items need to be tested for cement paste

1, 28d compressive strength

2, fluidity

3, setting time

4, bleeding rate

5, expansion rate

6 and air content?
