Of the hydraulic pump control system controlling the hydraulic components are placed corner by adjusting its variable to achieve. According to different forms of control can be divided into power control systems, traffic control systems and combinations of control systems such as three categories. Wherein the power control system exercise and power control, total power control, pressure control and variable cut off power control; flow control system with manual flow control, flow control positive and negative flow control, Sec maximum flow control, load sensing control and electrical flow control; combined control system is a combination of control power control and flow control, the most widely used in the hydraulic control unit.泰安嘉 and Heavy Machinery Co., Ltd. The first point: excavator loading conditions at the time, try to be in a higher position, and try to make the truck parked at the height of the work surface is almost the same; the reason is very simple, a stone, and you carried knee carried to the top of the head with a hammer the same? Specific can save much "effort" mean? If it is consistent height as before, it can improve the working efficiency of 40%. Cool! The second point: when the bucket cylinder and linkage, the first lever arm cylinder and head are at 90 °, each cylinder of the biggest driving force for excavators. The third point: excavation, bucket or ripper natural ground floor corner was maintained at approximately 30 °, closing the arm. Stick close to vertical mini excavators, the largest arm strength, can carry more load. These two bent arms like you mention something province effort, or is it straight arm, of course, it is bent chant. The fourth point: when one began to dig, not to arm extending to maximum effect range from about 80% of the best start. (When the maximum scope arm, the arm digging force minimum, excavation difficult). This point is generally more attention under the novice. Fifth: Stick digging range: 45 ° arm from the distal to the medial angle of 30 °. Because digging depth slightly different, but generally operate boom and bucket in this range should not be operated to the cylinder stroke end. Sixth: When making continuous mining, chassis placed on the forward direction, you can walk immediately after the end of excavation. If you go back, then, have to burn a lot of oil starting end. Seventh: during trenching work when the first dig trenches on both sides of the crawler excavators small price, and then tap the middle section. When digging in the middle so you could save a lot of thing, and also saves fresh. Eighth: the engine throttle position into the economy stalls. Let the engine idle select automatic idling function when, during excavation. Ninth point: to minimize the radius of gyration. Tenth point: excavation depth smaller domestic small excavators prices, while mining economy better, as far as possible the way sub-tap. Tap into in the next three, if one dug from the top of a low, first and foremost action to increase the scope, and secondly because the increasing power excavator range is reduced, reducing the work efficiency, which have to spend a lot of oil. These tips for small excavators saving operation much money, maybe even older machines usually are not noticed hand, but as long as the operation can develop good habits, over time, can really save considerable fuel costs.泰安嘉 and Heavy Machinery Co., Ltd. used mini excavators mini excavators Suihua price _ _ Kerry and Heavy Industries and Heavy Machinery Co., Ltd. by the 泰安嘉.泰安嘉 and Heavy Machinery Co., Ltd.
