What are the requirements for oil filling and oil draining of the tensile tester? Haida's after-sales service personnel returned to the customer and found that some customers would ask about the problem of oil filling and oil draining of the rally machine. Is there any skill, is it just a matter of pouring it in, it is definitely not, and it needs some tricks. Let's follow Haida's small series to learn more about how to fill the oil and drain the equipment.
1. Filling and draining oil
1) Open the dynamometer door and see the oil filter. The oil is injected into the oil tank. The oil quantity is about 28 liters. The oil level indicator on the outside of the oil tank is subject to the oil. The oil can be selected according to the oil specifications and functions. .
2) Before the machine is used, the stopcock installed from the fuel tank to the oil pump pipeline should be opened. When the scribe line of the stopcock is in line with the pipe, it means that the oil passage between the fuel tank and the oil pump is unblocked, such as the line is orthogonal to the pipe. When it is closed, it means closed.
3) When draining oil, open the nozzle on the left side of the dynamometer. The duration of the oil is generally determined according to the climate. If the oil starts to mix, it can be changed.
2. Oil selection and specifications
1) Use high quality medium viscosity mineral oil.
2) The oil should not contain water, acid or other mixture. Under normal temperature, it should not decompose the bottom of the tank or when it is dropped into the container, it will not become thick, and the oil must be filtered before being poured into the machine.
3) If the oil is improper, the valve and oil circuit will be blocked and the equipment may vibrate. These factors will affect the normal operation of the machine.
3, oil reference specifications:
1. Specific gravity: 0.86—0.97
2, freezing point: -15 ° C to -20 ° C
3. According to the actual situation, domestically produced 30-50 oil can also be used.
What are the requirements for oil filling and oil draining of the tensile tester? From the above description, it can be seen that whether the equipment is filled or drained, there are certain requirements, not just casual, so remember to fill the oil. Be sure to pay attention when draining oil.
