Hydraulic Wrench Pump

Why is it important to regularly inspect hydraulic pumps?For many industries with stringent requirements, torque calibration is performed on hydraulic torque wrenches before they leave the factory, and regular torque inspections are also carried out during use. At this point, someone might ask, why do high-pressure pumps for bolt stretchers or hydraulic torque wrench pump stations also need regular calibration checks? In response to this question, today's editor decides to share a customer case to answer this.Why do hydraulic torque wrench pump stations need regular calibration?Please provide the Chinese content you would like translated into American English.Recently, quite a fewAlonsoCustomers of our hydraulic wrenches have sought help from our technicians, stating that they have an old pump on-site that is malfunctioning, but they are unsure of the exact issue. According to the customer, their technicians adjusted the pump to the required pressure values based on the torque chart provided by the pump station and then torqued the bolts on several machines accordingly. Subsequently, inspectors adjusted a newly purchased pump station to the same gauge pressure value and checked the pre-tensioned bolts, discovering that they could be moved. This indicates that the pressure output from the pump station used for pre-tensioning the bolts was less than the pressure gauge readings. The customer, puzzled, expressed that although the pump station was purchased four to five years ago and has been in use without any issues, this problem has now arisen. Upon hearing this, we immediately identified the issue: the customer's pump stations had never been maintained or calibrated, causing the pressure gauge to malfunction and the readings to be inaccurate. Thankfully, the customer had performed a torque verification on the bolts after tightening, otherwise the consequences could have been severe. Therefore, it is not only necessary to regularly calibrate the hydraulic wrenches, but also the pressure gauges on hydraulic pump stations annually. Reminding customers to perform regular calibrations is actually part of the after-sales service. For after-sales services,AlonsoHydraulic torque wrenches have always adhered to"Adhering to the principle of 'thinking and acting as the customer does,' each time we assist with after-sales service, we go beyond the usual technical training and guidance, offering:AlonsoHydraulic spanner technicians repeatedly remind and instruct customers about the precautions during usage and post-maintenance, striving to help them avoid common issues proactively.
