Technical Interpretation: Single-stage rotary vane vacuum pump use and maintenance points

[Asia Pump Network News] Single-stage rotary vane vacuum pump is also called XD-type rotary vane vacuum pump. In the course of daily use have what needs attention, Xiaobian give you a detailed introduction to the use of single-stage rotary vane pump maintenance points. Technical Interpretation: Single-stage rotary vane vacuum pump use and maintenance points First, XD rotary vane vacuum pump vacuum oil XD rotary vane vacuum pump should be used in line with the standard SH0528-92 XD rotary vane vacuum pump oil. XD rotary vane vacuum pump oil with ISO ~ VG100 viscosity grade at ambient temperature of 10 ℃ ~ 40 ℃. Ambient temperature at 0 ℃ ~ 10 ℃ use ISO ~ VG32 viscosity grade vacuum pump oil. Vacuum pump operation must ensure that the oil level in the window 1 / 2-4 / 5 Department. Should always check the oil level and oil pollution (recommended once a week). If the oil level is too low XD rotary vane vacuum pump should be added to the appropriate vacuum pump oil window height 4/5 Department. If the oil is contaminated oil will be black, emulsified, thickening, oil change should be promptly. Second, 2XD-type rotary vane vacuum pump vacuum pump and oil filter replacement time XD rotary vane pump recommended pump for the first time after 150 hours of oil change. After every 500 hours of oil change. Oil change at the same time, should replace the oil filter. If the oil polluted black, emulsified, thickening should be timely oil change. Clean the pump before adding new oil. Third, cleaning, oil change steps 1, stop XD rotary vane vacuum pump to let go of hot oil. 2, spin on the drain plug operation for 5 to 10 seconds. 3, the oil exhausted. 4, into the cleaning oil (32 ordinary machine oil) to the height of the oil window 3/4 Department. 5, operating XD rotary vane vacuum pump 5 to 10 minutes. 6, stop pump, the oil let go. If the oil can not meet the requirements, repeat steps 4,5. 7, spin on the drain plug running 5 to 10 notes. 8, the oil exhausted. 9, into the provisions of the new XD rotary vane vacuum pump oil. Fourth, replace the exhaust filter If the pump temperature increased significantly, the motor current reaches or exceeds the rated current pump exhaust fumes are generated, you should check the exhaust filter is blocked, such as blockage, should be promptly replaced. Exhaust pressure gauge can be installed at the pump oil hole to check if the filter is clogged. Exhaust filter replaced when pressure exceeds 0.6 bar (gauge pressure). Fifth, clean the suction filter Inspiratory filter should be kept clean, so as to avoid pumping speed down. VI. Storage Methods If the pump is not used for a long time, drain the oil and clean the pump, and then inject the prescribed new oil into a dry place. Seven, XD-type rotary vane vacuum pump Other 1, the user to order maintenance spare parts, please inform XD rotary vane vacuum pump model and machine number. Pump model and machine number can be found on the pump nameplate. 2, due to some maintenance and repair work requires a certain amount of expertise, equipment and special tools, please contact the manufacturer for details. 3, pump handling should ensure that no oil. Can not hit the tubing, oil filters and other objects. (Editor: Li Juan) Further reading: Pump and Valve Tube Fittings Exhibition Information 2016 Exhibition Information

The RCU is connecting to the server center by TCP/IP and Ethernet protocol, each RCU could is connected to the hotel LAN and has an independent and unique IP address that is compatible with the Ethernet standard.
On the high voltage, there are replay outputs for the electrical equipment, the relays act as the switch and are controlled by the communication board that could receive the instruction from the 12V switches installed in the guest room.
The communication board is the core as the whole RCU like computer`s CPU, it mainly has two functions as below:
Receiving instruction signals from the switches, door plate, and sending signal to the 220V high voltage to turn on/off the lighting fixtures or control the air-conditione

The function of smart RCU as below:With strong stability;Good compatibility; Enhance the quality of hotel services ;Low cost,easy maintenance.
