Embodiment Construction
[0016] Such as figure 1 , figure 2 , image 3 As shown, a plunger pump assembly includes, the main pump and the auxiliary pump are welded and communicated through the pipeline 21, and it is characterized in that: the upper casing 1 of the main pump and the lower casing 2 of the main pump arranged at the lower part are welded as one, and the A gasket B7 is arranged on the inner edge of the upper casing 1 of the main pump, and a plunger sleeve 8 is placed inside the upper casing 1 of the main pump, and the plunger sleeve 8 is pressed and fixed on the upper casing of the main pump through a pressure cap 10 1, its pressure cap 10 is threadedly connected with the main pump upper casing 1, and the plunger rod 9 passes through the pressure cap 10 and is embedded in the plunger sleeve 8, so that the crankcase connecting rod drives the plunger rod 9 to move vertically up and down , and will not shake from side to side. The limit cover 3 is placed at the lower end of the plunger sle...

The invention discloses a plunger pump assembly. In the plunger pump assembly, a main pump is communicated with a secondary pump through a pipeline after welding. The plunger pump assembly is characterized in that an upper main pump shell is welded integrally with a lower main pump shell; the inner edge of the upper main pump shell is provided with a gasket B; a plunger sleeve is tightly fixed in the upper main pump shell through a pressing cap; a plunger rod passes through the pressing cap, and is embedded into the plunger sleeve; a limiting cover is arranged at the lower end of the plunger sleeve; a main pump hole which is communicated with the pipeline is formed in the limiting cover; the lower main pump shell is in threaded connection with a main pump valve seat; the main pump valve seat is provided with a main pump valve core and a counterweight block; a secondary pump valve seat is in threaded connection with a secondary pump body, and is locked and fixed with the secondary pump body through a nut; a secondary pump valve core is assembled on the secondary pump valve seat in a sliding way; the secondary pump valve seat is provided with a secondary pump annular cavity hole which is communicated with the pipeline; a gasket D is arranged on the inner edge of the secondary pump body; a limiting cover B is pressed into the secondary pump body through a secondary pump gland; the secondary pump gland is provided with an outlet. The plunger pump assembly has the advantages of simple structure, convenience in maintenance, reasonable design, high airtightness and the like.
Description
technical field [0001] The invention relates to a plunger pump assembly and belongs to the technical field of delivery systems for dosing devices. Background technique [0002] At present, the known plunger pump assembly such as the utility model patent applied by the applicant in China, the patent number is: CN200920146196. Pump assembly: press the plunger sleeve into the valve body so that the plunger sleeve cannot move freely, a plunger is arranged in the plunger sleeve, the gland A is screwed to the plunger sleeve, and an O is set above the gland A Type ring C and O-ring C play the role of sealing, and valve body B and valve body C are welded together. The disadvantages are that the processing is difficult, the required precision cannot be guaranteed, and the sealing performance is poor. It needs to be redesigned to ensure the forward-looking technology. Contents of the invention [0003] In view of the shortcomings of the above problems, the object of the present in...
