The daily maintenance and care of the precast concrete floor machine is very important to ensure its normal operation, extend its service life and ensure the production quality of precast floor slabs or concrete slab machine. The following are the specific maintenance and care methods:
Equipment cleaning
Overall cleaning: After each use of the equipment, the concrete, mortar and other debris remaining on the surface of the machine should be cleaned in time. You can use soft brushes, cleaning cloths and other tools with an appropriate amount of clean water to wipe, so as to avoid these debris from being difficult to remove after drying, and prevent them from corroding the surface of the equipment. For example, for parts such as the equipment housing and the outer surface of the conveyor, there should be no obvious accumulation of concrete.
Mold cleaning: The mold is a key component that directly affects the shape and dimensional accuracy of the prefabricated floor slabs, and it needs to be cleaned intensively. After the production is completed, the concrete remaining in the mold must be thoroughly removed. With the help of a special release agent cleaning tool, the residues in every corner of the mold can be cleaned to prevent it from affecting the molding quality and demolding effect of the next prefabricated floor slab/ precast concrete floor machine.
Mechanical parts maintenance
Transmission parts inspection: Transmission parts such as belts, chains, gears, etc. should be checked regularly for tightness. If the belt is too loose, it will slip, affecting power transmission, causing unstable or even abnormal operation of the equipment; if the chain is too loose, it is easy to decouple. Generally, every certain production cycle, it is necessary to adjust the tensioning device to ensure that the transmission parts are in a suitable tightness. At the same time, it is also necessary to check whether these parts are worn. If the wear is serious, they need to be replaced in time.
Reducer maintenance: The reducer plays a key role in adjusting the operating speed of the equipment. Check the lubricating oil level in the reducer regularly to ensure that the oil level is within the normal range. If the oil level is too low, it will affect the lubrication and heat dissipation effects and accelerate the wear of the parts. Replace the lubricating oil in the reducer according to the time interval required by the equipment manual. Generally, it needs to be replaced every few months or after a certain working time to ensure its good operating condition.
Motor maintenance: The motor is the power source of the equipment. Keep the surface of the motor clean to prevent dust from entering the motor to affect heat dissipation and normal operation. Regularly check the insulation performance, operating current and other parameters of the motor to ensure that they are within the normal range. If there is any abnormality, it is necessary to promptly check whether it is caused by the motor itself or external power supply problems, and take corresponding measures. In addition, the bearings of the motor should also be regularly filled with grease for lubrication to extend its service life.
Lubrication system maintenance
Regularly add lubricating oil (grease): There are many parts in the equipment that need lubrication, such as various shafts, joints, guide rails, etc. According to the requirements of the equipment’s instruction manual, add lubricating oil or grease of corresponding specifications on time and in a quantitative manner. For example, the spindle of some equipment needs to be filled with grease once a week to reduce friction between parts, reduce the degree of wear, and ensure the smooth operation of the equipment.
Lubrication system inspection: Check whether the pipeline of the lubrication system is unobstructed and whether there is any leakage. If the pipeline is blocked, the lubricating oil (grease) cannot reach the corresponding part, which will cause the parts to be damaged due to lack of lubrication; leakage not only wastes lubricants, but may also pollute the production environment and even affect other parts around the equipment. Once a problem is found, the damaged pipeline and other parts should be repaired or replaced in time.
Electrical system maintenance
Circuit inspection: Regularly check the electrical circuits of the equipment, including power lines, signal lines, control lines, etc., to see if there are any damage, aging, poor contact, etc. For example, a damaged outer sheath of the power line may lead to leakage risk, and poor contact may cause the equipment to run intermittently. If a line problem is found, it should be promptly wrapped with insulating tape or replaced with a new line.
Electrical component maintenance
Check electrical components such as contactors, relays, switches, sensors, etc. to see if their operation is sensitive and reliable. For example, if the contactor contacts are ablated, it will affect the on-off control of the circuit. It is necessary to polish the contacts or replace the contactors in time to ensure that the electrical system can normally control the operation, stop and conversion of each operating link of the equipment.
Mold maintenance
Precision detection and adjustment: Regularly use professional measuring tools to detect the dimensional accuracy of the mold, because during long-term use, the mold may be deformed due to force, wear and other reasons, resulting in the size of the prefabricated floor produced not meeting the requirements. Once the precision deviation is found, it is necessary to adjust it in time through calibration, repair and other means to ensure the molding quality of the prefabricated floor.
Anti-corrosion treatment: Molds are mostly made of metal and are prone to rust and corrosion. In addition to daily cleaning after production, anti-rust oil can be applied regularly for anti-corrosion treatment, especially when the equipment is idle for a long time, it is even more important to do a good job of protection in this regard to extend the service life of the mold.concrete slab machine.
Regular comprehensive testing and debugging
Operation test: At regular intervals (such as monthly or quarterly, depending on the frequency of equipment use), the equipment should be fully tested for no-load and load operation to observe the overall operation of the equipment, including the coordination of various components, whether the operating sound is normal, whether the quality of the prefabricated floor slabs produced meets the standards, etc., so as to promptly discover and solve hidden problems.
Calibration and debugging: According to the initial setting parameters of the equipment and production standards, the various parameters of the equipment are calibrated and debugged, such as vibration frequency, board making speed, pressure, etc., to ensure that the equipment is always in the best working condition and to ensure the stability and high quality of prefabricated floor slab production.
