Hydraulic presses are valuable tools in many applications, but like any other machinery, they can wear out or be damaged. For example, the rollers of the press are too old and damaged. In this case, the owner of the machine shop has two options: buy a new cylinder and replace the old cylinder or repair the existing cylinder. Which of the above would you choose? Buy a new cylinder or an old one?
If the machine owner chooses option one (purchase a new cylinder), the cost is high, but the machine shop will not encounter production delays. If the owner chooses the second method-repairing the old cylinder, the workshop will suffer from production delays and expensive downtime. Do you want to ensure that your hydraulic machine continues to operate safely and efficiently?Zhongyou Heavy IndustryProvide you with some preventive tips that will help you reduce unplanned downtime.
1. follow the preventive maintenance schedule of the hydraulic press:
Different brands make hydraulic presses, but these presses share the same core maintenance requirements, and each press comes with a preventive maintenance plan provided by the manufacturer.
This schedule details the steps that press operators must follow when maintaining the hydraulic machine. By following these steps, not only the hydraulic machine operator can reduce downtime, but also extend the life of the hydraulic machine.
The following is a sample three-month maintenance list:
1. Hydraulic inspection:
1) Tightness of hydraulic joints;
2) Full range pressure regulation;
3) Tightness of inserts and connections;
4) Check whether the press leaks.
2. Electrical inspection:
1) Check whether the conduit and wire are damaged;
2) Check whether the start button is correct;
3) Whether the limit switch is damaged or sealed.
At the end of this list, indicate the measures that need to be taken. For example, if you find that the power cord shows signs of damage during the inspection, indicate the measures that need to be taken, such as replacing wires and conduits. What you need to know is that this is not the only list. You can have:
1) a six-month list;
2) Nine-month list;
3) Annual list.
Periodic replacement of damaged components is 2:
When the components of the hydraulic press are faulty, it is recommended to replace them. If the parts are replaced irregularly, the press may be further damaged, which may increase the repair or replacement cost of the press.
An important reason why most machine repair shop owners may not replace faulty components is to avoid any downtime. This is correct, because unplanned downtime will affect productivity, and therefore, this leads to delayed delivery of customer orders.
If this happens, you will lose a lot of business, because your customers will choose to cooperate with competitors. Despite the problems with the components, you can still choose to continue to use the hydraulic press. The disadvantage is that the machine may fail.
If this happens, not only will a lot of business be lost, but it will be difficult to recover. We recommend replacing the faulty components immediately. Yes, you may suffer some downtime, but in the long run, you will recover and save expensive repairs and time.
3. check the security system:
The safety of your employees/hydraulic press operators should be a top priority, why, you may ask, there are many dangers in the operation of presses and other machinery.
For example, press operators may suffer pinch injuries or heavy objects falling onto their feet, and they may also trip or come into contact with chemicals such as hydraulic oil.
If your workers come into contact with hydraulic oil or lubricants, the chemicals can cause dermatitis. In addition, toxic fumes are harmful, especially from mold-making materials.
To ensure that fatal injuries do not occur, please check the safety system every day. Such safety systems include:
1) Anti-restart motor control;
2) Push-button station with start and stop function;
3) bulletproof blanket;
4) pop-up curtain kit;
5) Stop the safety circuit (check once a day to ensure that it is always safe);
6) If you find that the safety equipment is unreliable, please replace the components before starting operation.
4. closely monitor the health of hydraulic oil:
Your hydraulic machine is similar to your vehicle or any other machinery. Basically, when the amount of oil is low or there is dirty oil, it cannot operate optimally. If your machine is running with dirty oil or insufficient oil, The service life of the press will be shortened.
What you need to know is that it is very easy to monitor the health of hydraulic oil, you only need to prepare a list. First, take an oil sample. For this operation, please use a probe. This operation can help you find out the presence of pollutants.
The good news is that your manufacturer will specify the required oil cleanliness level, which makes it easy for you to know whether the oil contains contaminants.
If there are water or dirt particles in the oil, it must be replaced. This will help restore the lubricity of the oil. Remember, please hire a reputable oil testing company to obtain the correct results.
In addition to changing the oil, you also need to change the oil filter. This ensures that the correct filter micron level is always reached. The dial of the hydraulic press indicates when to change the oil filter. If the indicator turns red or yellow, Please replace the filter.
5. other methods:
There are more preventive tips that will help extend the life of the hydraulic press, including checking the operating temperature, recording press data, and viewing data.
Remember, it is important to keep the hydraulic machine clean and avoid delaying problems such as malfunctions or damaged components.
