For the bladder accumulator NXQ-A-40/31.5-L-Y, when a new spare parts package needs to be replaced, ensuring the stability of the system pressure is the primary task of the technician. Let’s talk about the specific steps for installing a new repair kit and how to ensure the stability of the hydraulic system pressure during the installation process.

Before installing a new repair kit, some preparations must be made. First, make sure that the power supply to the hydraulic system is disconnected to prevent accidental startup. Then, release the pressure of the system and let the system be at rest. Next, prepare the necessary tools, such as wrenches, screwdrivers, cleaning agents, etc., as well as the new spare parts package NXQ-A-40/31.5-L-Y. Finally, check whether the spare parts package is intact and make sure that the accessories inside are complete.

When removing the old repair kit, be careful to avoid damaging the surrounding parts. First, loosen the fixing bolts and slowly remove the old spare parts package. Next, clean the installation location of the spare parts package and make sure that the installation surface is clean and oil-free. If any worn or damaged parts are found, record them in time for subsequent replacement.

When installing a new spare parts package, make sure that each step is done carefully. First, check whether the seal of the new spare parts package is intact. If it is damaged, replace it with a new one. Next, gently place the new spare parts package on the installation location to ensure that the seal fits completely. Then, tighten the fixing bolts with appropriate torque to ensure that the spare parts package is firmly installed in place. Throughout the process, be careful not to over-tighten the bolts to avoid damaging the spare parts package or the seal.

After installation, the new repair kit needs to be inflated. First, connect the inflation nozzle to the nitrogen bottle, and then slowly inflate the spare parts package until the specified pressure value is reached. During the inflation process, closely monitor the pressure gauge to ensure that the pressure does not exceed the specified upper limit. After inflation is completed, it is also necessary to perform an exhaust operation to release excess gas and ensure that the pressure in the spare parts package is stable near the set value.

After installing the new repair kit, it is also necessary to perform a system pressure test to ensure that the pressure is stable. First, start the hydraulic system and observe whether the pressure gauge reading is stable near the set value. Then, perform several manual or automatic operations to observe the changes in system pressure. If you find unstable pressure or leakage, you need to stop the system immediately and check whether there is a problem with the installation of the spare parts package or whether there are other parts that need to be replaced.

After installing a new spare parts package, you also need to maintain and monitor the system regularly. Check the seal of the repair kit regularly to ensure that there is no leakage. At the same time, check the working status of the pressure gauge and other monitoring equipment to ensure that it can accurately reflect the pressure level of the system. If any abnormality is found, take timely measures to avoid problems caused by unstable system pressure.
