Problems solved by technology
However, there are many kinds of hydraulic components at present, and various manufacturers cannot coordinate and standardize the functions, specifications, types, performances, parameters, etc., so there are many phenomena that "one hydraulic component needs to be equipped with a set of hydraulic pumps".
Leading to low utilization rate, large duty cycle, high cost, waste of resources, etc.
Since the separate configuration of the hydraulic pump requires more complex parts and pipeline design, it increases the difficulty of installation, commissioning, maintenance, and also reduces the effectiveness, safety and service life of the long-term operation of the device

Embodiment Construction
[0038] In order to make the above objects, features and advantages of the present invention more comprehensible, specific implementations of the present invention will be described in detail below in conjunction with the accompanying drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. However, the present invention can be implemented in many other ways different from those described here, and those skilled in the art can make similar improvements without departing from the connotation of the present invention, so the present invention is not limited by the specific implementations disclosed below.
[0039] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected ...

A central hydraulic pump comprises a supporting seat, a high-pressure oil tank, a low-pressure oil tank, a switch assembly, a plurality of pressure-regulating reversing valves and a driving mechanism. A plurality of high-pressure oil outlet holes arranged separately are formed in the lateral wall of the high-pressure oil tank, a plurality of low-pressure oil returning holes arranged separately are formed in the lateral wall of the low-pressure oil tank, a high-pressure input pipe opening of each pressure-regulating reversing valve is communicated with the corresponding high-pressure oil outlet hole, a high-pressure output pipe opening of each pressure-regulating reversing valve is communicated with a hydraulic element, and a pressure reduction returning pipe opening of each pressure-regulating reversing valve is communicated with the corresponding low-pressure oil returning hole. According to different pressure needed by the different hydraulic elements, the relative positions of a first passage, a second passage and the high pressure input pipe opening, the high pressure output pipe opening and the pressure reduction returning pipe opening of each valve sleeve shell are changed, hydraulic oil is permitted to or prevented from being input from the high-pressure oil tank to the hydraulic elements and returning from the hydraulic elements to the low-pressure oil tank, and therefore one hydraulic pump can control the motions of the multiple hydraulic elements of different functions relatively independently.
Description
technical field [0001] The invention relates to the technical field of hydraulic pumps, in particular to a central hydraulic pump. Background technique [0002] Due to the particularity of hydraulic devices, many industries are widely used. However, there are many kinds of hydraulic components at present, and various manufacturers cannot coordinate and standardize the functions, specifications, types, performances, parameters, etc., so there are many phenomena that "one hydraulic component needs to be equipped with a set of hydraulic pumps". . It leads to low utilization rate, large duty cycle, high cost, waste of resources and other results. Since the separate configuration of the hydraulic pump requires more complex parts and pipeline design, it increases the difficulty of installation, commissioning, maintenance, and also reduces the effectiveness, safety and service life of the long-term operation of the device. Contents of the invention [0003] Based on this, it i...
