Due to the wide application of hydraulic technology in mechanical equipment, on-site management of the hydraulic system is particularly important. Especially the quality of hydraulic equipment management that plays a major role in hydraulic equipment is directly related to whether the equipment can maintain good working accuracy and performance for a long time, as well as the failure rate and work efficiency of hydraulic equipment, product processing quality, and enterprise production efficiency. And economic benefits. Hydrotech teaches you how to manage hydraulic cylinders and various components of the hydraulic system.
Good-performance mechanical equipment is important, but it is more important for a piece of equipment to carry out on-site management such as proper use and maintenance. This kind of relationship between "enterprise" and "holding one's career" is like a way of keeping one's health, and good maintenance can lead to health and longevity. The same is true for hydraulic equipment. If you manage well, and focus on prevention is more important than cure, you can reduce failures, reduce the time for shutdown and "treatment", greatly improve the service life and performance of hydraulic cylinders and hydraulic systems, and economic benefits Greatly improve, security can also be guaranteed. If we pay attention to and implement the management of hydraulic machinery and equipment, the failure can be eliminated in the bud without causing major accidents and harm.
After the hydraulic system is put into use, in order to facilitate maintenance and management, the system can be divided into several areas for management. The hydraulic system can be divided into: executive agency area management, control agency area management, power agency area management, and auxiliary parts management.
1. Regional management power agency.
The main inspection items for the management of the mechanical device area are: use a pressure gauge or other pressure gauges to observe the working conditions of the hydraulic pump. Regularly check the working stability of the pressure valve and draw the pressure-flow characteristic curve. Propose the change rule of hydraulic pump efficiency, check the reliability of the oil suction port seal of the hydraulic pump, and carry out the inspection and maintenance of the wear state. Systems equipped with energy storage devices should also check the working conditions of the energy storage devices, mainly to check whether air leakage, oil leakage, and air pressure are within the specified range.
2. Regional management of regulatory agencies.
The control mechanism includes a hydraulic control mechanism and a control mechanism. The management content of the hydraulic control organization includes: the accuracy and reliability of the commutation, whether there is impact and noise, whether the flow control is stable and reliable (usually carried out in conjunction with the regional management of the actuator), and whether the stroke control is accurate. Operating mechanism management mainly includes checking the reliability of baffles, handles, levers, pressure relays and sequence valves, as well as observing oil pressure or air pressure, and checking lines.
3. Auxiliary area management.
(1) The content includes joint sealing and reliability, vibration, noise and safety measures.
(2) Hydraulic oil. Use an oil level cylinder to check the amount of oil, and the amount of oil must be within the minimum limit specified. The second is oiliness identification. The appearance of hydraulic oil is compared with hydraulic oil samples for factors such as the color, smell, and luster of the hydraulic oil, and quality reports are regularly compiled. When conditions permit, quantitative analysis can also be conducted through experiments. In addition, use a thermometer to observe the changes in the oil temperature to keep the oil temperature within the specified range.
(3) Oil filter and heat exchanger. Frequently check the filtering effect of the oil filter and air filter inside and outside the fuel tank. Clean or replace according to the maintenance plan, analyze and filter impurities, and determine the cause of contamination. There are refrigerators or heaters in the box. In addition to checking the heat exchange effect, check the pipes and water pipes for leaks. At the same time, the heat exchanger pipes should be cleaned frequently to remove dirt and improve work efficiency.
4) Oil tank. Pay attention to changes in the environment around the fuel tank. Frequently observe the condition of the paint on the inner wall of the fuel tank and check whether the sealing of each part is reliable.
4. Regional management administrative agency.
The content of actuator area management is visual inspection and periodic wear appraisal. The appearance inspection includes the sealing performance of the sealing device, stable moving speed, accurate stroke control, whether the working mechanism is connected correctly, whether the protective device is reliable, related torque, output force, lubrication, climbing, etc. Through identification, the cause of wear can be found, and improvement measures can be proposed, so as to realize the identification of regular wear.
