Problems solved by technology
The latter, because the oil pump in the distribution valve oil circuit frequently switches between the maximum displacement and the minimum displacement, resulting in an increase in failure rate, shortened working life, and insufficient performance
The above-mentioned defects not only adversely affect the working reliability of the concrete pump, but also increase the manufacturing and maintenance costs of the product
In particular, the existing concrete pump hydraulic system only has the pumping capacity of constant speed push, so that the concrete pump is not capable of overcoming resistance, and pipe plugging failures are prone to occur during work

Embodiment Construction
[0014] In the speed-up and booster device of the hydraulic system in this embodiment, the connecting oil circuit 1 is a hydraulic pipeline, as shown in FIG. 1 , which has an input terminal T (1-2) and an output terminal B. The accumulator 10 of the device is a commercially available XL4 type accumulator, the check valve 11 is a commercially available S10 type check valve, the oil pump 2 is a commercially available A8V type oil pump, and the oil pump 3 is a commercially available A10V type oil pump. Relief valve 12 adopts commercially available DB10 type relief valve. Each part is connected according to the technical solutions mentioned above. This example hydraulic system speed-increasing booster device of the present invention that constitutes thus proves to be effective through trial production and trial use, and fully meets the design requirements.

The present invention introduces a hydraulic system speed increase and power adding apparatus which is provided with a connection oilchannel (1), wherein a oil pump (2) is pipe jointed on the oilchannel between a input terminal T1 and an output terminal B; a one way valve (11) and a oil pump (3) is pipe jointed between the oilchannel and the input terminal T2, wherein the oilchannel is between a output terminal B and the oil pump (2); a energy accumulator (10) and a over-flow valve (12) with an output terminal T is pipe jointed on the oilchannel between the one way valve (11) and a oil pump (3). When oilchannel of system distributor valve changes direction, the present apparatus can make the oil cylinder of the distributor valve changes direction quickly and make the pumping oil cylinder obtain pumping capability that can increase speed and add power, thereby can make the dynamic performance and reliability of the oil channel of the hydraulic system improved and strengthened effectively, also make the oil pump work under more smooth work status, improve pumping dynamic performance such as the concrete pump significantly.
Description
technical field [0001] The invention relates to a speed-increasing booster device suitable for a hydraulic system. Background technique [0002] The hydraulic system, especially the concrete pump hydraulic system, is used in the concrete pump to drive its pumping device and distribution device. In the existing hydraulic system, one of the working oil circuits is supplied by a single oil pump; the other is supplied by double pumps to the pumping oil circuit and the distribution oil circuit respectively. Their hydraulic systems are only capable of pumping at a constant rate. When the main oil pump works in the constant power control area, the former usually has insufficient power of the oil cylinder of the distribution valve or a large hydraulic shock of the oil circuit due to the increase of the pressure of the oil pump and the decrease of the displacement. The latter is because the oil pump of the distribution valve oil circuit is frequently switched between the maximum di...
