How To Solve The Problem of No Pressure On Shearing Machine
In my experience with shearing machines, encountering the problem of no pressure on shearing Machine can be quite frustrating and can significantly disrupt production. Understanding the root causes of this issue is essential for effective troubleshooting. Over the years, Iโve developed strategies to identify and resolve various factors that lead to a lack of pressure in shearing machines. In this article, I will outline practical steps on how to solve the problem of no pressure on shearing machines, sharing insights that will help you quickly diagnose and rectify this common issue, ensuring smooth and efficient operation.
Why No Pressure On Shearing Machine
The fact that the no pressure on shearing Machine is one of the most common problems with shears, and it usually means that the shears cannot cut the plates. If the above situation occurs, you can take the following steps to check the fault one by one:
Step 1: Check if the oil pump suction port has suction. No suction pump is damaged. Also, check whether the oil pump suction port is leaking when the oil is filled. Wuxi Shenchong recommends that you replace the new hydraulic oil according to the manufacturer’s specified cycle, to cause inconvenience in the production process.
Step 2: The maintenance personnel needs to observe whether the oil pump is running. Usually, the oil pump is broken, and the CNC shearing machine will not only cut the fixed plate but also emit abnormal noise when the machine is running. To determine if the oil pump is damaged, the maintenance personnel can directly reach into the fuel tank and then step on the footswitch to feel whether the oil pipe can absorb oil normally. If the oil is not properly sucked, the pump is damaged; if the oil is normal, it is not a problem with the pump.
Step 3: Check if the relief valve spool is clogged and there is a blockage. The maintenance personnel needs to remove the relief valve spool for cleaning. If the relief valve spool is clogged, there will be no pressure on the entire hydraulic system.
Step 4: It may be that the two-way four-way solenoid valve spool is not flexible, and the maintenance person needs to remove the valve core for cleaning.
The above steps are to assist maintenance personnel in troubleshooting in a simple and easy order. When it is impossible to accurately know the exact fault, it is recommended that the maintenance personnel follow the above steps to check one by one, which can help the maintenance personnel find the source of the fault in the shortest time.
