Problems solved by technology
Hydraulic components are usually composed of reciprocating pistons, and long-term high-frequency movements are likely to cause wear or even damage to hydraulic components
The existing one-piece integrated structure hydraulic components cannot be replaced, which is very inconvenient to use
Furthermore, the existing hydraulic pump body is made of steel, and the integrated structure will make the use of steel a large amount and the cost is very high
[0003] In addition, the oil circuit in the existing hydraulic pump is mostly one-way circulation, that is, the actuator can only move forward, and the reset needs to be done manually, which is very inconvenient for the user and the work efficiency is very low

Embodiment 2
[0055] Such as Figure 13 and Figure 14 As shown, the recessed hydraulic pump provided in this embodiment includes a pump body 100, a driving assembly 2', a hydraulic assembly 3', an oil circuit assembly 1', a reversing assembly 4' and an oil tank 5'. One end of the pump body 100 has a mounting hole. The driving assembly 2' includes a motor 21' and an eccentric wheel 22', and the motor 21' is arranged at one end of the pump body 100. The hydraulic assembly 3' includes a hydraulic seat 31' and at least one oil slip switch 32'. The hydraulic seat 31' is detachably installed in the mounting hole in a recessed manner, and the hydraulic seat 31' has an oil return hole. At least one oil slide switch 32' is arranged on the hydraulic seat 31' and arranged along the circumference of the eccentric wheel 22'. The oil slide switch 32' is in contact with the eccentric wheel 22' and is turned on or off driven by the eccentric wheel 22'. The oil circuit assembly 1' is connected to the c...

The invention provides an inward-concave type hydraulic pump. The hydraulic pump comprises an oil path assembly, a drive assembly, a hydraulic assembly, a reversing assembly and an oil tank. The oil path assembly comprises an oil path shell and a plurality of oil pipes arranged in the oil path shell, and an installation hole is formed in one end of the oil path shell. The drive assembly comprises a motor and an eccentric wheel, and the motor is connected with one end of the oil path shell. The hydraulic assembly comprises a hydraulic base and at least one oil lubrication switch. The hydraulic base is detachably arranged in the installation hole in an inwards-concave manner, and the hydraulic base is provided with an oil returning hole. The oil lubrication switches are arranged on the hydraulic base and distributed in the circumferential direction of the eccentric wheel, the eccentric wheel drives the oil lubrication switches to be turned on or off, and the oil returning hole and the oil lubrication switches are connected with the multiple oil pipes. The reversing assembly is arranged on the side wall of the oil path shell and extends in the direction perpendicular to the axis of the oil path shell, the reversing assembly is connected with the multiple oil pipes and changes the flowing direction of oil in the oil path assembly. The oil tank is arranged at the other end of the oil path shell.
Description
technical field [0001] The invention relates to the field of hydraulic pumps, and in particular to an inner hydraulic pump. Background technique [0002] The hydraulic pump is the power component of the hydraulic system. It is driven by an engine or an electric motor. It sucks oil from the hydraulic oil tank, forms pressure oil and discharges it, and sends it to the actuator. Hydraulic pumps are used in a wide range of fields, such as transportation, construction, railways, bridges, fire protection, aviation, aerospace, military and many other fields. In existing hydraulic pumps, the hydraulic components are integrated inside the pump body. Hydraulic components are usually composed of reciprocating pistons, and long-term high-frequency movements are likely to cause wear or even damage to hydraulic components. The existing one-piece integrated structure hydraulic components cannot be replaced and are very inconvenient to use. Further, the existing hydraulic pump body is ma...
