Abstract
A hydraulic end and a fracturing pump. The hydraulic end includes a body and a functional device. The functional device includes at least one of a base plate, an end cover assembly, and a packing assembly, and the functional device is detachably fixedly connected to the body. The above hydraulic end can solve the problem of relatively high production costs caused by replacement of an entire hydraulic end body in case of failures such as leakage caused by wear of a packing or cracking of an end cover under a force.
Claims20
A hydraulic end of a fracturing pump, comprising:
- a valve box and a first valve assembly,
- wherein the valve box comprises a first valve cavity,
- wherein the first valve assembly comprises a valve seat, a valve member, an elastic member, and a valve support,
- wherein the valve seat is embedded into the first valve cavity, the valve member is movably disposed relative to the valve seat, wherein a valve seat surface that seals and stop the valve member comprises two portions with a continuous transition,
- wherein the valve support is fixedly disposed at a port of the first valve cavity adjacent to an intersecting plunger cavity of the valve box, and
- wherein the elastic member is elastically connected between the valve member and the valve support.
A hydraulic end of a fracturing pump, comprising:
- a valve box and a first valve assembly,
- wherein the valve box comprises a first valve cavity,
- wherein the first valve assembly comprises a valve support, the valve support comprising a support body, a leg portion, and a protective portion, and
- wherein the leg portion is connected to an inner wall of the first valve cavity, and the protective portion shields a connection area between the first valve cavity and an intersecting plunger cavity of the valve box.
A valve support, used for a hydraulic end of a fracturing pump, comprising:
- a support body, a leg portion, and a protective portion,
- wherein the support body comprises a first end surface and a second end surface, wherein the first end surface and the second end surface are arranged opposite to each other along an axis of the valve support, wherein the protective portion extends obliquely from the first end surface in a direction away from the axis of the valve support, and wherein the leg portion extends obliquely from the second end surface in a direction away from the axis of the valve support.
