Use hydraulic tankThe important role of the hydraulic oil tank in the hydraulic system for the separation of oil, heat the oil contained in the air and eliminate foam. Choose to use the tank first thing to consider its capacity, general mobile equipment take 2 to 3 times the maximum pump flow rate, fixed equipment to take 3 to 4 times; Second, consider the oil tank when the system is all hydraulic oil tank may not extend below the minimum oil level when the oil level after retracting the cylinder must not exceed the maximum oil level; and finally consider the tank structure, the traditional fuel tank separator and precipitated dirt can not play the role of a vertical bulkhead should be installed along the longitudinal axis of the tank . Leave gaps between the separator tank at one end and the end plate on both sides of the separator space communication, the hydraulic pump oil inlet disposed at one end on both sides of the separator is not connected, so that the oil into the oil and return the distance between the farthest, hydraulic tank up some more cooling effect.Market research industry developmentsPiston pump is the pump in one, but the whole pump industry is a typical investment-driven industries, the market demand is subjected to national macroeconomic policies, which is subject to macroeconomic policy Teyou water, construction, energy and other sectors of greater impact. Hydraulic piston pump is a piston pump, the hydraulic industry's annual output value has not reached 10 billion yuan business, even more than 500 million yuan of annual output value of only a handful of companies, with total annual sales of the entire industry not as a of total sales. When supporting industries do not have the ability to compete with foreign companies, import goods on the domestic market will be strong artificial means of control and nothing to take into account. Most of the profits of construction machinery spare parts have been removed to the fact that not only allow the host manufacturer painful and helpless. Based on this situation, OEMs as well as funds from other industries are constantly entering the hydraulic industry. Just over one billion yuan investment into the hydraulic industry. But this trend is no doubt to increase the intensity of competition within the industry, changing the original industrial structure and order. Piston displacement is a typical hydraulic machinery, driven by a prime mover, the input of mechanical energy is converted into fluid pressure energy, and then entered as pressure, flow into the system, it is the power source of the hydraulic system, because it can transport liquid under high pressure, so the industrial production and daily life in various industries have been widely used.Market conditionsPiston pumps and other pumps in shipbuilding, oil exploration, truck cranes and other widely used. 2008 ship production reached 15,000 tons, accounting for 21% of the number dwt world market, 2015 will become the world's largest shipbuilding country. To ensure the normal navigation or mooring boat, crew and passengers to meet the daily needs of each boat must be equipped with a certain amount of, can play a relevant role in marine mining, marine pump is one of the important auxiliary equipment. According to incomplete statistics, in various ship auxiliary machinery and equipment, and the total number of all types of marine pumps
