What are the common faults of the reversing valve of the portable pallet stacker

We all know that the hydraulic system is a very important part of the portable pallet stacker, no matter what the forklift price is. If the hydraulic system has problems, the portable pallet stacker will not continue to work. Therefore, today the forklift manufacturer will talk to you about the common faults and solutions of the reversing valve, an important part of the hydraulic system of the portable pallet stacker.

The reversing valve of portable pallet stacker is used to control the communication, cut-off and reversing of hydraulic oil flow, as well as the parts for pressure unloading. Many friends often ask why the valve element does not act when the reversing valve is reversing? There are several reasons: first, the valve core is blocked; Second, the valve body is deformed; Third, the centering spring in the middle position is broken; Fourth, the operating pressure is not enough. In this case, first ensure that the operating pressure is higher than the specified minimum value, and then disassemble the reversing valve for cleaning. After cleaning, check whether the centering spring is broken. If it is broken, replace it in time. Check whether the valve body is deformed. If it is deformed, reinstall the screws of the valve body to make the compression force even. No matter what the forklift price is, in case of serious deformation, replace the screws directly.

What should we do if the reversing valve of the portable pallet stacker cannot complete the operation as required during the operation? The reasons are as follows: First, there are impurities in the oil or thermal expansion, which makes the valve core inflexible or stuck; Second, the spring is too soft or too hard to make the oil flow unobstructed; Third, the fitting between the valve core and the valve hole is too tight or the clearance is too large. No matter what the forklift price is, in case of such a problem, the reversing valve should be cleaned first, and then check whether the valve element needs to be replaced. Next, check whether the tension of the spring meets the requirements, and replace the spring according to the severity of the problem. Finally, check the fit clearance between the valve core and the valve body. If necessary, bore or replace the valve core.

These are the problems that friends often ask about the reversing valve of portable pallet stacker. In case of any problem, the first thing to do is to clean the parts, and then carefully check them to find out the root cause of the problem and see whether they need to be repaired or replaced. No matter what the forklift price is, you can easily solve problems by doing this.
