Hydraulic station manufacturers due to the nature of the system and oil. Generally speaking, the operation of the system will cause certain damage to the hydraulic oil used in the morning, so when in use, there will be oil wear. In order to improve the service life of hydraulic oil, we generally limit the temperature at the time of use. Generally speaking, it is to control the temperature within 65 degrees.

So we should always pay attention to the temperature shown by the thermometer. But also according to the state of the oil, both the replacement of the oil. Generally, the oil used is inspected every three months, and it will be replaced if it is not suitable. However, for the general hydraulic station, the average hydraulic oil must be replaced at least once every year. All hydraulic jacks have interfaces of 3/8 "-18NPT, and each hydraulic jack is equipped with high flow quick joints to ensure the free flow of liquids. Some hydraulic jacks have threaded assembly holes at the bottom of the cylinder block, which is easy to install. Most hydraulic jacks with a working capacity of more than 50 tons have lifting rings or handles to facilitate on-site carrying and placement.
The working capacity of a hydraulic jack is the force that can be exerted under a given large working pressure. The maximum operating capacity of all hydraulic jacks in this catalog is calibrated at a maximum pressure of 700Bar (10,000 psi). Each is tested at 125% of its rated operating pressure. Normal operation seal intact, no oil leakage, in order to ensure reliable on-site operation, before the product factory, all hydraulic jacks have been strictly tested, tested before delivery. Hundreds of different types of cylinders are produced, regardless of the industrial application, such as lifting, pushing, supporting, bending, pressing, punching and other similar operations. No matter the carrying capacity, travel, length, or size restrictions and other single or double acting. Solid or hollow plungers, there are always hydraulic jacks for your high-strength applications.
Handle lifting: The process of lifting the handle is also the process of absorbing oil. The oil in the oil storage pipe of the manual hydraulic pump is sucked into the plunger through the low pressure valve, and the process continues until the plunger is filled, the pressure rises to 1MPa, the oil pump opens the low pressure relief valve, and the oil is returned to the oil storage pipe again.
Pressure handle: The process of pressing the handle is the process of converting the mechanical energy of the oil pump into hydraulic energy to do work. At this time, the high pressure plunger works, the low pressure valve is closed, and the oil flows from the valve block into the tubing, thus pushing the hydraulic cylinder to do work. When the pressure continues to rise beyond the rated pressure of 70MPa, the high pressure valve inside the oil pump opens, and the oil spills from the high pressure valve back to the oil storage pipe, thus ensuring that the supply pressure is always maintained at 70MPa. We usually call the high pressure valve here a safety valve. The safety valve is a necessary component to ensure that the oil pump does not exceed the load. When the oil is continuously pressed to the hydraulic cylinder, this is a process of external work, and the internal pressure becomes smaller. In order to ensure the continuous work of the oil pump, we need to keep shaking the handle to ensure the pressure required for the system to work.
