Several suggestions on the selection of oil tanks for hydraulic lifting platforms

1367 hydraulic lifting platform is an intelligent lifting and transportation machinery equipment. The hydraulic lifting platform lifting system relies on hydraulic actuators, also known as hydraulic drive lifting platforms. The key functions of hydraulic oil tank in the hydraulic system software of some hydraulic mechanical equipment such as lifting platform and hydraulic lifting platform are oil storage tank, heat pipe heat dissipation, separation of gas in the oil and removal of foam plastic. There are three areas to consider when using oil tanks for hydraulic lifting platforms: Point: Considering its volume, generally portable machinery and equipment (sh è b è i) should take 2-3 times the total flow rate of the pump, and mobile machinery and equipment should take 3-4 times. Secondly, considering the oil level in the fuel tank, when all hydraulic cylinders in the system software extend outward, the oil level in the tank must not be less than the minimum oil level, and when the hydraulic cylinders contract, the oil level must not be higher than the oil level. Thirdly, considering the structure of the fuel tank, the partition inside the traditional fuel tank cannot serve the purpose of pre settling dirt. A vertical partition should be installed along the longitudinal centerline of the fuel tank, leaving a space between one end of the partition and the end plate of the tank to connect the indoor spaces on both sides of the partition. The layout of the inlet and outlet holes of hydraulic pumps is not on either side of the connected end of the partition, making the distance between the inlet and pump oil relatively far. The hydraulic fuel tank also serves as a heat pipe for heat dissipation. {5}
