Abstract

The invention discloses a manual pressure regulating device for a plunger pump. The manual pressure regulating device comprises a pump shell. The side wall of the pump shell is provided with a pressure regulating pipe orifice. The pressure regulating pipe orifice is provided with a detachable regulating part. The regulating part comprises an outer pipe and an inner pipe. The outer pipe is separably connected with the inner pipe. A regulating handle penetrates through the outer pipe and the inner pipe. When pressure relief is needed, a user can directly hold the head of the regulating handle and lift the regulating handle, so that a gap between a conical regulating head and a pressure relief hole is enlarged, the high pressure in the plunger pump is released, oil injection maintenance is greatly facilitated, and operation is convenient. The manual pressure regulating device for the plunger pump is simple in structure, obvious in effect, low in cost and high in practicability.

Description

technical field [0001] The invention relates to a plunger pump, more precisely, a manual pressure regulating device for the plunger pump. Background technique [0002] The plunger pump is an important device of the hydraulic system. It mainly relies on the reciprocating movement of the plunger in the cylinder to change the volume of the sealed working chamber to realize oil suction and pressure. Due to the high pressure in the cavity of the plunger pump, the pressure needs to be reduced to a suitable pressure value during oil injection maintenance, but the existing method can only completely empty the cavity, resulting in too low pressure in the cavity. Contents of the invention [0003] The invention mainly solves the technical problems existing in the prior art, thereby providing a manual pressure regulating device for a plunger pump. [0004] Above-mentioned technical problem of the present invention is mainly solved by following technical scheme: [0005] A manual pr...
