Since 2006, Focus on rubber seals

Common sense of hydraulic pump installation

by:ORK      2022-10-14
The deviation of the coaxiality between the hydraulic pump drive shaft and the motor drive shaft is less than 0.1MM. Generally, flexible couplings are used to connect the pump shaft. It is not allowed to use the V-belt to directly drive the pump shaft to rotate, so as to prevent the pump shaft from being subjected to excessive radial force and affect the seal. The normal operation of the pump; The rotation direction of the hydraulic pump and the oil inlet and outlet should be installed as required; The oil suction height of various hydraulic pumps is generally less than 0.5M. Precautions after the installation of the new hydraulic pump 1) Pay attention to the operating conditions within three months of the new machine’s operation. During the operation of the new machine, you should grasp the operating conditions and check, such as the maintenance of the parts, whether the screws are loose, and whether the oil temperature is abnormal. Normal rise, whether the hydraulic oil deteriorates quickly, check whether the conditions of use meet the regulations, etc. (2) Do not add load to the seal immediately after the hydraulic pump is started. After starting, the hydraulic pump must be idling without load for a period of time (about 10 minutes to 30 minutes), especially when the temperature is very low, it must go through the warm-up process to make the hydraulic pressure If the loop cycle is normal, add the preload and check the operation status. (3) Observe the change of oil temperature. Pay attention to check the change of the highest and lowest oil temperature, and find out the relationship between the oil temperature and the external ambient temperature, so as to know whether the capacity of the cooler and the capacity of the oil storage tank is compatible with the surrounding conditions and the conditions of use. Troubleshooting of the system can also be traced. (4) Pay attention to the noise of the hydraulic pump. The new hydraulic pump has less initial wear and is easily affected by air bubbles and dust. Poor lubrication at high temperature or overloaded operating conditions will cause adverse consequences and cause the hydraulic pump to have abnormal effects. (5) Pay attention to check the display value of the seal gauges. Observe the vibration status and stability of the pressure gauge of the hydraulic circuit, the pressure switch light signal, etc. at any time, so as to find out whether the hydraulic circuit is functioning properly as soon as possible. (6) Pay attention to observe the action of the machine (for the modified pump) Improper design of the hydraulic circuit or poor manufacturing of the components are not easy to find in the initial use stage, so special attention should be paid to the action state that appears under various operating conditions. (7) Pay attention to the adjustment in each valve Fully understand the use of pressure control valve, flow control valve and directional control valve, and pay special attention to the adjustment range and limit, otherwise adjustment errors will not only damage the machinery, but also pose a threat to safety. (8) Check the status of the filter The filter in the loop should be taken out and cleaned regularly, and the status of the filter screen and the dirt adsorbed on the net should be checked, and the quality, quantity and size should be analyzed, so that the degree of pollution in the loop can be observed, and even according to This infers where the source of the contamination is. (9) Regularly check the changes of hydraulic oil Check and analyze changes in the deterioration, discoloration and pollution of hydraulic oil every one or two months to ensure the normal operation of the hydraulic transmission medium. (10) Pay attention to the leakage of the piping part. Whether the piping of the hydraulic device is good or not can be seen after running for a period of time. Check whether there is oil leakage and whether the piping is loose. (11) Always pay attention to abnormal phenomena and find abnormal sounds, vibrations or abnormal signals of the monitoring system. There must be a reason. When an abnormal phenomenon is found, immediately find the circuit diagram and follow the diagram to find out whether the abnormal phenomenon is caused by a temporary error. . Assess the need for parking. For example, pressure, load, temperature, time, start-up, and stop all contain the reasons that may cause abnormal phenomena. Usually, it should be analyzed and discussed item by item. Company website: https://www.orksealing.com/
