The hazards of excessive hydraulic oil temperature are as follows.
1. Hydraulic oil viscosity, volumetric efficiency and hydraulic system working efficiency are all reduced, leakage increases, and even mechanical equipment can not work properly.
2. The parts of the hydraulic system expand due to overheating, which destroys the original normal fit clearance of the relative moving parts, resulting in increased frictional resistance and easy seizure of the hydraulic valve. At the same time, the lubricating oil film becomes thinner and mechanical wear increases, resulting in pumps and valves. Precision mating surfaces of motors, motors, etc. are disabled or scrapped due to premature wear.
3. Accelerate the deterioration of the rubber seals, shorten the service life, and even lose its sealing performance, causing serious leakage of the hydraulic system.
4, oil vaporization, water evaporation, easy to make the hydraulic components cavitation; oil oxidation to form a gel-like deposit, easy to block the oil filter and small holes in the hydraulic valve, so that the hydraulic system can not work properly.
Therefore, the excessive temperature of the hydraulic oil will seriously affect the normal use of the machine, reduce the service life of the hydraulic components, and increase the maintenance cost of the construction machinery.

IECEx Approved Coriolis Mass Flow Meter
Zhejiang Sealand Technology Co., Ltd. is a trustworthy manufacturer of Mass Flow Transmitter, Coriolis Mass Flow Transmitter, Coriolis Mass Flow Sensor, Mass Flow Sensor & Mass Flow Sensor Coriolis, ATEX, IECEx & CE approved.
The meter can be connected with computer as follows. Connect the meter and computer with a USB-to-RS485 converter( converter A+ end to transmitter A+ end, B- to B-, and GND to GDN); turn to device manager of the computer to check COM port connected with meter. Start the software, select the right COM port and click Connect; do not change any other parameters (if you do not know the right one, click Automatic options on the left, click Connect, plug & unplug the transmitter, and then check if it is connected). You can click Connect on the tool bar to disconnect or connect again. It will shown Connected/Not Connected at the bottom of this interface.
The flow direction is settable. There are 4 options, forward(default), reverse, absolute value & bi-direction. There is a direction mark on the sensor. Forward means the same direction with the mark on sensor, the meter will only count the flow in this direction; reverse means the opposite direction of the mark, the meter will only count the reverse direction; bidirectional means that the meter will measure both directions, it increases when it is forward and decreases when reverse; absolute means it increases no matter it is forward or reverse.
