Brushless dc motor controller is very common now, brings convenience for people's work, brushless dc motor controller is for the use of oil for transport, on different occasions have different delivery requirements, here to see how the process of oil discharge operation. If you want to put the brushless dc motor controller box body drained all the oil from, you can unscrew a drain plug at the bottom of the box body, the oil off. Brushless dc motor controller in the outside under the condition of discharge of oil, liquid level height not more than 30 mm distance tank roof, to ensure the lubrication and cooling of the bearings in the local machine. When jack working chamber volume is too large, need to pay up the fuel tank, ensure that the discharge of oil liquid level after the minimum height not less than 100 mm in order to avoid empty absorption. Brushless dc motor speed control type hydraulic controller first run after 500 h, oil tank cleaning and oil filter should be replaced. Use visual and assay method of testing oil, should be timely change the oil when oil deterioration. Oil change must be cleaning tank and oil filter at the same time. If you have any scrap metal oil or water, should find reason side by side is out of order. In the liquid level lower bearing in a short time by splashing of oil and plunger spring to lubricating oil, fuel tank about oil and machine oil filter system under 230 eye/inch copper wire mesh, oil screen should often clean to prevent clogging, when using the oil tank temperature should not exceed 60 ℃, when it is necessary to take appropriate measures to cool.
