In the test machine of the hydraulic waste paper baler equipment, the no-load test machine is a necessary process. This is a link in testing the quality of the manufacturer, and it is also a guarantee work for the customer to carry out the production.
Today, we will introduce in detail the purpose of the no-load test machine of the hydraulic waste paper baler and the several links to be paid attention to. Through those indicators, we can judge whether the equipment is working normally:
1. Oil pump
The oil pump is the power source for the pressure of the waste paper baler. During the no-load test machine, check whether the pressure of the oil pump is too high during unloading, whether the sound is normal, and whether the liquid level in the fuel tank indicates bubbles that inhale air, etc.
2. Relief valve
The second indicator to check is the working state of the overflow valve of the hydraulic waste paper baler. If there is no abnormal phenomenon during the adjustment of the relief valve, let the oil cylinder perform multiple reciprocating motions or the oil motor rotating motion without load to remove the gas in the system. Secondly, check whether the safety valve, pressure relay, etc. work reliably. Observe through the pressure gauge. System pressure, and adjust the pressure value of the safety valve to make it within the specified range.
3. Hydraulic oil
The third indicator is to check the temperature of the hydraulic oil. When the waste paper baler is tested for a period of time without load, check whether the temperature of the hydraulic oil is normal.
The above are the main inspection objects of the hydraulic waste paper baler during the no-load test run. However, you should not only check these items, but also pay attention to the other working conditions of the entire equipment, and whether the various components are working properly to ensure that they are put into production. Normal work before operation.
