What are the common faults, solutions and preventive maintenance techniques of the hydraulic press?

Nadun Machinery Manufacturing Co., Ltd. hydraulic equipment is widely used in aerospace, nuclear power, petrochemical, auto parts, bicycle parts, hardware, instrumentation, medical equipment, household appliances, household ware, sanitary Ware and other manufacturing industries.

Since all heavy operations must be performed on the hydraulic press, you may encounter some problems related to this machine, here are some of the most common problems, and how to solve and avoid them. In this paper, Nadun Machinery Manufacturing Co., Ltd. brings the common faults, solutions and preventive maintenance skills of hydraulic press.

Common problems and solutions of hydraulic press:

1) oil spill:

One of the most reported problems is an oil leak, and you will notice oil around the plunger, the hose end fitting, and the hydraulic line.

Solution:

Make sure that the recommended oil is used for the hydraulic machine and that all accessories are tightened.

2) overheating:

Excessive pressure and friction, as well as contamination or degradation of hydraulic oil, may lead to overheating of the press. The temperature of the hydraulic press must not exceed 150 °F, because overheating may damage the sealant.

Solution:

Make sure you do not squeeze excessively, and change the oil regularly and clean the filter.

3) slow pressure accumulation:

Generally, the hydraulic press should reach the required pressure level in about one second, which should be longer than this time, which means that there is a problem with the pump and the fluid does not leak into the plunger fast enough, this may be caused by leakage or dirt mixed in the liquid.

Solution:

Make sure to check the pump and surrounding mechanisms such as overflow valves and motors to ensure everything is normal and clean.

4) Abnormal noise:

If you hear the impact or knock sound of the hydraulic press, there may be signs of air in the fluid, and you may also encounter abnormal movement of foam and actuator, lubrication loss, overheating and component damage are some of the problems caused by this.

Solution:

1. Check the liquid level and make sure it is correct, and check whether the seal of the pump shaft leaks.

2. Regular maintenance and inspection will prolong the service life of the hydraulic press, but unfortunately it will not make it permanently durable when you find more serious problems, such as broken racks, when electrical problems and pump pressure are insufficient, it is time to say goodbye and make sure you take good care of your technology and make full use of it!

Two, preventive hydraulic maintenance four skills:

If you operate hydraulic equipment, it is important to maintain it correctly. This does not mean that attention is paid only when errors are found. Preventive maintenance is very important to maintain the effective operation of hydraulic equipment throughout the year, and can also help you avoid expensive and long maintenance.

Are you not sure how to participate in preventive hydraulic maintenance? Continue to read the four tips on how to correctly maintain hydraulic equipment!

1) Check the liquid level and replace it if necessary

One of the most important parts of the hydraulic system is fluid, because fluid will transfer pressure from one part of the system to another. However, it is important to ensure that the fluid level remains in the best state and there are no particles in the fluid. Make sure that the fluid is checked and replaced when necessary.

2) Check the filter and replace it if necessary

Filters are important to keep the liquid clean and sticky. However, with the passage of time, the hydraulic filter may be blocked. This is not good because it increases the pressure of the system and does not always allow the hydraulic oil to move freely. Make sure to check the hydraulic filter and replace it regularly according to the manufacturer's instructions.

3) make sure that the rated values of hoses and valves are correct

Hydraulic hose is essential for any hydraulic system. When selecting hydraulic hoses for the system, you need to ensure that they have been properly evaluated for the temperature and pressure of the system to be operated on them. You should also ensure that the hydraulic hoses and valves are regularly checked for cracks or signs of deterioration. These hydraulic components are very sensitive and will cause serious damage to the hydraulic system if problems occur.

4) thoroughly check whether there is any problem with the equipment

Last but not least, you should also conduct a thorough inspection of hydraulic equipment on a regular basis. Find any work components or areas that require attention. If you cannot solve the problem yourself, you need to find a professional.
