?????????? ??? XD020 rotary vane vacuum pump one. XD series vacuum pump installation method: 1) The installation of the pump should be placed horizontally. As the pump is running almost no vibration can be generally not fixed, the pump at the bottom of the shock pad has a metric screw hole to fix the pump. Do not push the pump on the ground, so as not to damage the cushion. To ensure that the pump is well cooled and easy to service, it is advisable to leave a clearance of 0.4 m in front of the pump inlet and outlet. To facilitate the oil drain can be installed with a drain pan base. Pump shipped without oil. After installation, slowly inject the specified vacuum pump oil through the fill port (see Maintenance, Service 1) to 3/4 of the height of the oil window. 2) Electrical connections Electrical wiring must be carried out by a qualified electrician and an appropriate motor overload protection device should be used. XD-01 and 02 matching single-phase motor, the user should pay attention to the use of 15A sheath line and plug, socket and other configuration independent dedicated line with the matching line connection in strict accordance with the motor nameplate diagram. Three-phase asynchronous motor wiring must be completed after checking the motor rotation. Correct motor rotation: The motor shaft rotation is counterclockwise as seen from the rear fan end of the motor. Check the rotation, the suction port should be opened or covered with rubber plate (thickness 4mm or more) completely cover the suction port, power 2-3 seconds. If it is correctly rotated, it will feel strong suction at the suction port or the rubber plate will be tightly sucked. If the reverse is the transfer of any two of the three power cord. Note: The pump is running in the wrong direction for a long time and will be damaged. 3) The size of the cross section of the air intake pipe of the system should be not less than the size of the suction port and the connection length should be as short as possible. Screw connections with Loctite 515 or Teflon tape vacuum sealed. If the exhaust gas containing dust impurities and a small amount of water vapor must be installed on the pump inlet vacuum filtration device. If necessary, take over the exhaust, the exhaust pipe should be tilted down. 4) Start After determining the oil level can start the vacuum pump. After starting for the first time and changing the wiring for the first time, the motor must be checked for rotation before the vacuum pump can be started. 5) Before normal operation, the intake pipe valve should be closed to allow the pump to operate for more than 15 minutes at the ultimate pressure. This effectively removes water vapor from the gas. The motor should not be started frequently. It is suggested to install a solenoid valve on the intake pipe of the pump in the intermittent cycle. Turn off the solenoid valve in the non-working phase so that the pump will work at the limit pressure. In this way, the motor consumes less power but can effectively Protect the vacuum pump. Note: 1, the normal operation of the oil separator, pump body, pump cover, etc. surface temperature will have played 70 ℃, do not touch by hand. 2, pump operation can not be refueled. 6) The ultimate pressure measurement limit pressure should be directly in the pump suction port with a compressed-type vacuum gauge measuring pump for the first time, long-term shelved use, after the new oil should be used to close the inlet for at least one hour after the operation to pump to work Temperature and pump oil fully degassed to measure the ultimate pressure. Second, XD series vacuum pump maintenance, repair 1) vacuum pump oil XD, XQ series vacuum pump should be used in line with SH0528-92 standard vacuum pump oil. Use ISO-VG32 viscosity grade vacuum pump oil at ambient temperature between 0 ° C and 10 ° C. Ambient temperature at 10 ℃ -40 ℃ use ISO-VG100 viscosity grade vacuum pump oil (for the original 1 # vacuum pump oil). Vacuum pump operation must be maintained at the oil level in the window 1 / 2-3 / 4 Department. Should always check the oil level and oil pollution (recommended once a week). 2) replace the vacuum pump oil and oil filter If the oil contaminated and black, emulsified or thickening should be timely oil change. At the same time, change the oil filter and clean the pump before adding new oil. Cleaning, oiling steps: 1, stop the pump to release the hot oil. 2, spin on the drain plug, run 5-10 minutes. 3, the oil exhausted. 4, into the cleaning oil (32 ordinary machine oil) to the height of the oil window 3/4 Department. 5, run the vacuum pump 5-10 seconds. 6, stop pump, the oil let go. If the oil can not meet the requirements, repeat steps 4,5. Until the oil is released through the hour-like shape. 7, spin on the drain plug, running for 5-10 seconds. 8, the oil exhausted. 9, into the provisions of the new oil. 3) more to reach the exhaust filter If the pump temperature increased significantly, the motor current reaches or exceeds the rated current, the pump exhaust fumes are generated, you should check the exhaust filter is blocked, such as clogging, should be promptly replaced in Install the exhaust pressure gauge at the pump filler hole to check if the filter is clogged. The exhaust filter can be changed when the pressure exceeds 0.6 bar (gauge pressure). 4) Storage If the pump is left unused for a long time, drain the oil and wash the pump, then inject the specified fresh oil into a dry place. 5) Others a. If users want to order spare parts for maintenance, please inform pump model and machine number. Pump model and machine number can be found on the pump nameplate. b. For some maintenance work requires some expertise, equipment and special tools, please contact the manufacturer for details. c. Ensure that no oil is removed during pump handling. Can not hit the tubing, oil filters and other objects. This article is provided by Foshan Dongshan Science and Technology Co., Ltd.
