What are the common faults of one-way valve of electric forklift?

In recent years, electric forklift has been used more and more widely, and more and more enterprises have purchased electric forklifts to create higher benefits for enterprises. Many drivers are prone to panic when encountering faults of electric forklifts. On the one hand, they are worried about affecting their work, and on the other hand, they do not know how to deal with them. Therefore, today the forklift manufacturer will tell you what common faults are found in the check valve, an important part of the electric forklift hydraulic system, and how to deal with them.

The one-way valve of the electric forklift is used to prevent the reverse flow of oil or compressed air in the pneumatic system. If we find that the one-way valve makes abnormal noise during operation, there may be several problems: first, the flow through the one-way valve exceeds the specified value; Second, the one-way valve resonates with other components; Third, there is no pressure relief device in the valve. At this time, the driver needs to be patient. If the problem is caused by the first reason, it is necessary to replace the check valve with large flow or reduce the actual flow so that its maximum value does not exceed the specified value. If the problem is caused by the second reason, properly adjust the pressure of the check valve or adjust the spring. If the problem is serious, you need to change the stiffness of the spring. The forklift manufacturer told us that if the problem is caused by the third reason, the pressure relief device should be installed or the circuit of the pressure relief device should be supplemented.

If there is leakage between the valve core and the valve seat of the one-way valve of the electric forklift, it may be caused by the following reasons: first, poor sealing of the valve seat; Second, the valve core or valve seat is roughened; Third, the valve seat is broken. At this time, we need to check one by one, and repair or replace according to the severity of the problem. If the check valve fails, it may be because the check valve element is stuck. It may be that the valve body hole is deformed, the valve hole has burrs or the valve element is deformed. Another reason for one-way valve failure is that the spring is broken or missing. At this time, the forklift manufacturer told us that we should first check whether the spring is missing, and then check whether the valve core and valve body hole have problems, and repair or replace them as needed.

The above are the common faults and solutions of the one-way valve of the electric forklift. Don't worry when encountering problems. The driver needs to be patient in troubleshooting one by one and then solve them in a targeted way. If you have any questions about the electric forklift, you can consult the forklift manufacturer.
