It is helpful for enterprises to prolong the use of mechanical diapers in summer and reduce the maintenance cost in case of abnormal temperature. This paper puts forward the following maintenance suggestions for the problems that are easy to appear in the diaper equipment in summer.
(1) Hydraulic system failure.
In high temperature environment, pipeline explosion, joint leakage, solenoid valve coil burning, hydraulic valve blockage and noise fault often occur in hydraulic system; Aging circuit in summer is more likely to cause cracking and short circuit fault; In high temperature season, the electrical components in the control cabinet are also prone to failure, and the key control components such as industrial controller may also suffer from death, slow operation speed, control failure and other failures.
(2) Lubrication system failure.
The long-term operation of adult diaper machinery under high temperature will lead to poor performance of lubrication system, oil deterioration, wear of chassis and other transmission systems, and affect the paint layer and metal structure.
(1) ) on site emergency treatment of high temperature fault.
Boiling is one of the common faults caused by high temperature of diaper mechanical equipment. When the water temperature is too high, do not rush to open the water radiator cover for heat dissipation. It is easy to spray hot water. Make up water after natural cooling; According to the operation experience and the mechanical operation specification of diapers, the operator should stop the operation immediately, do not shut down the engine, idle the engine, open the shutter to increase the air flow, slowly reduce the water temperature and release a large number of bubbles generated by the cooling system.
When the engine idles for a few minutes, the water temperature drops and no longer boils. Wrap the water radiator cap with a towel or veil. Carefully open part of the water radiator cap to release the water vapor and ensure that the water vapor of the water radiator is released. Then open the water radiator cap and open the water radiator cap. Remember that your arms are not exposed to avoid facial water and prevent hot water from scalding your face.
(2) When adding coolant, it is best to add the same type of coolant as the water radiator. Unless it is treated urgently, do not add tap water at will. When adding cooling water to the water supply radiator, you must wait until the water temperature drops to about 70 ℃; It should be cooled gradually, and do not add too much water at one time, that is, let the engine idle, add water slowly, and the water flow is long, so as to ensure the safety of operators and machines.
(3) When the brake or other components are overheated, do not cool them with water to reduce their service life and function, resulting in deformation or even cracking of components. Natural cooling must be stopped.
(1) Do a good job in early maintenance.
In summer, it is best to maintain the machinery comprehensively, replace the three oil filters of the engine, replace or adjust the adhesive tape, check whether the performance of the fan, pump, generator and compressor is reliable, and maintain, maintain or replace it if necessary.
When working in high-temperature areas, properly increase the oil viscosity level, check whether the cooling system and fuel system are unblocked, replace aging wires, plugs and hoses, and check and tighten fuel pipes to prevent fuel leakage; Clean the oil and dust on the engine to ensure that the engine is light and has good heat dissipation.
(2) Do a good job of lubrication.
Equipment lubrication is one of the important methods to prevent parts from wear and failure. Lubrication plays an important role in the transmission and maintenance of equipment, which will affect the performance, accuracy and service life. For lubrication, five or three levels of filtration shall be conducted according to the specified lubrication time, lubrication implementer, lubricating oil, parts, quantity, storage filtration, distribution filtration and refueling filtration inspection. Reduce friction and damage to ensure normal operation.
In the high temperature season in summer, the lubrication time should be adjusted first, which is 0.5-1 times shorter than that in spring and autumn. Observe the oil quality. The temperature of fatty oil is easy to change. If the temperature rises, add oil properly (grease gun up to three times). If the temperature is slightly higher and then decreases slowly, lubrication is proved to be effective. Insufficient bearing oil causes an increase in lubrication and temperature.
If the temperature remains unchanged or only rises and falls after refueling, it indicates that the bearing is worn, or there is a serious lack of oil, or even the internal oil is dry. Therefore, the grease should adjust the lubrication time, and formulate the lubrication plan and discharge time when it is due.
Liquid oil mainly pays attention to emulsification. In the high temperature season in summer, the lubricating oil runs more than 20 degrees higher than that in spring, autumn and winter. The oil keeps heating up and cooling down in an open environment. Because oil is also a hydrocarbon, it will produce water and then emulsify the oil. Oil emulsification will greatly reduce the viscosity and double the original film efficiency of the lubricating part. As you can imagine, the friction will double. Therefore, a lubrication plan should also be formulated to pay attention to inspection, prevent trouble in advance and realize predictive maintenance.
Conclusion: the summer maintenance of adult diaper machine should follow the principles of timeliness, rationality and comprehensiveness, which is conducive to the operation of the equipment and adapt to the external temperature and working conditions. Track management, master its performance dynamics, and formulate targeted and universal maintenance plans. The equipment must be inspected and maintained regularly to prevent failure, ensure reliable operation and improve efficiency and efficiency. Maintain regularly according to the mechanical operation conditions and operation standards. The contents include monitoring operation status, replenishing or changing lubricant, and regular disassembly and inspection. Maintenance items during operation include bearing rotation sound, vibration, temperature, state, etc.
