(1) Neat: tools, workpieces and accessories are placed in order; Complete safety protection devices; The lines and pipes are all finished.
(2) sales: cleaning the inside and outside of the equipment; Each sliding surface, screw, gear, rack, etc. There should be no oil pollution and scratches; No oil leakage, no water leakage, no air leakage and no electric leakage in all parts; Clean up waste and rubbish.
(3) Lubrication: refuel and change the oil on time, and the oil quality meets the requirements; Oil jug, oil gun, oil cup, linoleum and oil circuit are clean and complete, with bright oil mark and smooth oil circuit.
(4) Safety: personal appointment and machine handover system shall be implemented; Be familiar with the equipment structure, abide by the operating rules, use the equipment rationally, and carefully maintain the equipment to prevent accidents.
Content of field equipment maintenance management
Equipment maintenance can be divided into daily maintenance and regular maintenance according to time; According to the maintenance methods, it can be divided into general maintenance, regional maintenance and key equipment maintenance. Maintenance work generally includes on-site management and maintenance work such as inspection, inspection, adjustment, lubrication, disassembly and cleaning, repair and replacement.
Regional maintenance of equipment
Regional maintenance of equipment refers to dividing an enterprise into several regions according to the ownership or type of equipment in the production area. Maintenance workers have a clear division of labor, work closely with the operators, and supervise and guide the equipment operators in the areas under their jurisdiction to operate correctly, use reasonably and carefully maintain the equipment. Carry out patrol inspection, master the equipment operation, and undertake certain equipment maintenance work; Responsible for the implementation of assessment indicators such as equipment integrity rate and failure rate in the area. Regional maintenance is a post responsibility system to strengthen equipment maintenance management, serve production and mobilize the enthusiasm of maintenance workers.
The work content of regional maintenance is:
A, the daily maintenance man on duty actively patrol the installation level and accuracy of equipment within the responsibility area, and make detailed records and file them for future reference.
C For precision equipment with special requirements on the environment (constant temperature, constant humidity, vibration prevention and dust prevention), enterprises should take corresponding measures to ensure that the accuracy and performance of the equipment will not be affected.
D, precision, rare, key equipment in the daily maintenance, generally do not remove parts, especially optical components. When disassembly is needed, it should be carried out by professional maintenance personnel. If abnormal phenomena are found in the operation of the equipment, it should be stopped immediately, and it is not allowed to run with illness.
E, operate in strict accordance with the processing range specified in the equipment operating instructions, and do not use equipment beyond specifications, weight, load and pressure. Precision equipment can only be used directly for finishing, and the machining allowance should be reasonable. When processing the surfaces of castings and blanks, sandblasting or painting should be carried out in advance.
F lubricating oil, wiping materials and cleaning agents of the equipment shall be used in strict accordance with the specifications and shall not be replaced at will. Lubricating oil must pass the test and must be filtered before being added to the oil tank.
R, precision, rare equipment in non-working hours to add protective cover. If it stops for a long time, it should be wiped, lubricated and idling regularly.
W, equipment accessories and special tools should have special shelves for storage, to keep clean, prevent corrosion and bruise, and shall not be lent out or used for other purposes.
Equipment lubrication is an important link in the field use and maintenance of mechanical equipment. Correct and reasonable equipment lubrication can reduce the friction and wear of equipment parts, prolong the service life of equipment, give full play to the efficiency of equipment, reduce functional loss and prevent equipment corrosion and thermal deformation. On the contrary, ignoring equipment lubrication and improper equipment lubrication will accelerate equipment wear, cause frequent equipment failures and accidents, accelerate the deterioration of equipment technical conditions, and affect product quality and output. Therefore, equipment managers, users and maintenance personnel should pay attention to equipment lubrication.
Oil leakage control standard for field production equipment
(1) Oil leakage: the oil stain is not obvious, and it will not appear within five minutes after wiping off the oil stain.
(2) Oil leakage: oil stains are obvious, and some oil drops are formed. Oil stains or oil drops appear within five minutes after wiping.
(3) Oil leakage point: If there are obvious oil traces or oil drops, it is an oil leakage point.
(4) Oil-tight equipment: Oil-tight equipment refers to equipment with no oil leakage at the static joint surface and no oil leakage at the dynamic joint surface. 80% of the joint surface does not leak oil, and the oil leakage part does not leak more than one drop within three minutes, which basically belongs to oil-free equipment.
(5) Equipment with serious oil leakage: The equipment with serious oil leakage has one of the following conditions, or an oil leakage point drops more than three drops a minute.
(6) General oil leakage equipment: If there is any oil leakage, but it is not serious enough, it is a general oil leakage equipment.
(7) The treatment is qualified: the static joint surface does not leak oil, and the dynamic joint surface (except all moving parts such as hand-lubricated guide rail, lead screw and polished rod) does not leak oil.
