Precautions for using mobile self-priming oil pump

&The workplace should strictly comply with the specific standards and requirements for explosion-proof environments.
. The self-priming pump is not allowed to idle at will when it is not working. It is best not to idle for more than two minutes when it is working.
< . The electrical circuit system should be carried out in accordance with oil tank operation, protection, safety common sense and procedures, and be reliably grounded.
< . Whether the rotation direction of the self-priming pump meets the requirements. (If you look from the pump to the motor, the direction of rotation is counterclockwise)
< . If the motor cannot rotate normally when the power is turned on, turn off the power immediately to find out the cause to prevent the motor from burning out.
< . Before the end of the work, you can lift the suction oil away from the oil surface, drain the remaining oil in the pipe, and then turn off the power.
< . When storing this self-priming pump, it is best to store it in a professional room. When using it, do not let it get soaked by rain or other liquids. Try to avoid contamination of the small wheels with oil and grease.
< . Connect the power supply and start the motor instantly. Check whether the steering direction from the motor windshield is consistent with the direction of the arrow indicated on the front cover of the pump body. Otherwise, the power supply connector should be adjusted.
< . After the preparation of electrical circuits and oil pipelines is completed, the work can be started. After starting for about one minute, oil should be sucked and transported normally. Otherwise, inspection, analysis and cause troubleshooting should be carried out.
< . The power cord should use high-quality rubber-sheathed cables with *.+* specifications or slightly larger capacity. The power supply is, and the power switch should use the above air switch. At the same time, the length of the cable and the distance between the switch and the pump working point should be shortened as much as possible.
< The oil pipeline uses steel wire braided rubber hose with the same specifications as the skateboard pump (the discharge pipe can use nylon hose or oil-resistant rubber pipe). The female end joint of the CB standard hose is connected and tightened and sealed with a pipe clamp before being separated. Connect to the inlet and outlet of the pump body respectively. The length of the suction pipe should not exceed 1 meter, and the length of the discharge pipe should not exceed 1 meter.
< . This series of pumps has good self-priming properties. There is no need to pour liquid in before starting the pump, and there is no need to add additional lubricant during daily work.
< This self-priming pump uses an elastic coupling to transmit power, which can compensate for minor deviations caused during installation, and can play a good buffering role when the pump is subject to inevitable hydraulic shock during operation.
< After the work is completed, unscrew the oil drain valve located at the lower part of the pump casing, twist the motor from the motor connector, and drain the oil in the pump.
< . The cast iron slide pump needs to be maintained when transporting water quality materials. It should be inspected every fifteen days. Anti-rust powder can be added to prevent the pump body from rusting and affecting normal operation.
