Abstract
The utility model discloses a reciprocation pump fluid end and belongs to the technical field of reciprocation pumps. The reciprocation pump fluid end is composed of a pump body, a combination valve component and a plunger sealing component, wherein the plunger sealing component is installed on the lower portion of pump body and in a hole which is coaxial with a crosshead channel at a motive power end, the combination valve component is installed on the upper portion of the pump body and in a hole which is perpendicular to the plunger sealing component, a padding adjusting device is arranged on the pump body and at the front end of the plunger sealing component, a discharge valve is arranged on the upper portion of the combination valve component, and a suction valve is arranged on the lower portion of the combination valve component. The movement direction of the suction valve and the discharge valve in the combination valve component is the same with the direction of the self gravity of the suction valve and the discharge valve, adaptability to media is strong, and sealing reliability of the valve component is greatly improved. A liquid inlet is higher than the suction valve, suction in performance of the pump is greatly improved, and operation reliability of the pump is increased. Assembling and dismantling of the plunger sealing component and assembling and dismantling of the combination valve component are conducted in two directions and do not affect mutually, padding is assembled and dismantled at the front end of the pump body, a space for adjusting the padding is large, and safety and convenience are achieved. Maintenance time is saved, maintenance efficiency is improved, and labor intensity of workers is reduced.
Description
Technical field
The utility model belongs to the reciprocating pump technical field, is specially a kind of reciprocating pump hydraulic-end.
Background technique
Reciprocating pump hydraulic-end is the parts of most critical in reciprocating pump, is also the maximum parts of easily damaged parts, and its structure is directly determining back and forth pump performance, affects the convenient and safe property of working service.The combination brake switch and proporting fluid end is one of at present the most frequently used fluid end structure, and the combination brake switch and proporting assembly all is mounted in plunger front end and coaxial with plunger usually.the filler controlling device is arranged on the sealed letter body of plunger back-end, the dismounting of filler and filler are regulated and are all carried out in the cavity of power end front end, during due to the coaxial installation of combination brake switch and proporting assembly and plunger, suction valve, expulsion valve sinks under Gravitative Loads naturally, suck for solving, discharge naturally sinking of valve plate, must give suction valve, the expulsion valve guiding, and the guiding clearance is very little (generally 0.05～0.15mm), the impact that contains like this impurity in real work due to medium in inhomogeneous or medium tends to cause suction valve, the expulsion valve bite, affect the normal operation of valve.
In addition, combination brake switch and proporting assembly and the coaxial installation of plunger must dismounting combination brake switch and proporting assemblies during the dismounting plunger, and be very inconvenient.Also to regulate be to carry out in the cavity of power end front end for Packed dismounting and filler, and the cavity volume of power end front end own is just little, also the inside other component also have been installed, useful space is very limited, has greatly increased the dismounting difficulty.Have and carry out filler regulate in the cavity of power end front end, when regulating due to filler, plunger also in to-and-fro motion, adds that useful space is very little, and the usage space of instrument is limited, and is very inconvenient during the adjusting filler, also danger close, and the event of hurting sb.'s feelings happens occasionally.
Summary of the invention
The utility model is intended to overcome the deficiencies in the prior art, and a kind of reciprocating pump hydraulic-end is provided.
Reciprocating pump hydraulic-end of the present utility model, by the pump housing, combination brake switch and proporting assembly and plunger seal module composition, pump housing bottom, with power end crosshead slideway coaxial hole in the plunger seal assembly is installed, in pump housing top, the hole vertical with the plunger seal assembly, the combination brake switch and proporting assembly is installed, the pump housing of plunger seal assembly front end is provided with the filler controlling device.
As further improvement of the utility model, combination brake switch and proporting assembly internal upper part is provided with expulsion valve, the bottom is provided with suction valve.
This device, pump housing top have been installed the combination brake switch and proporting assembly, and the plunger black box is installed in pump housing bottom, and the combination brake switch and proporting assembly is vertically arranged with plunger, and the filler controlling device is arranged on the pump housing of plunger front end.Carry out from two different directions respectively when changing combination brake switch and proporting and filler, be independent of each other.Filler dismounting and filler are regulated and are carried out at pump housing front end.
Reciprocating pump hydraulic-end of the present utility model, reasonable in design, the suction valve in its combination brake switch and proporting assembly, expulsion valve moving direction and suction valve, to discharge valve plate deadweight direction identical, less demanding to the guiding of suction valve, expulsion valve, the guiding clearance is relatively large.Adaptability to medium is stronger, has greatly increased the sealing reliability of valve assembly.Liquid entering hole has improved the suction performance of pump greatly higher than suction valve, has increased the operational reliability of pump.The dismounting of the dismounting of plunger seal assembly and combination brake switch and proporting assembly is independent of each other at both direction, and is very large at pump housing front end dismounting filler and filler adjusting space, safe ready.Save maintenance time, improved maintenance efficiency, reduced workman's labor intensity.
Description of drawings
Fig. 1 is reciprocating pump hydraulic-end structure schematic diagram.
Embodiment
Reciprocating pump hydraulic-end as shown in Figure 1, to be consisted of by the pump housing 1, combination brake switch and proporting assembly 2 and plunger seal assembly 3, the pump housing 1 bottom, with power end crosshead slideway coaxial hole in plunger seal assembly 3 is installed, be provided with plunger 4 in plunger seal assembly 3, in the pump housing 1 top, the hole vertical with plunger 4, combination brake switch and proporting assembly 2 is installed, the pump housing 1 of plunger 4 front ends is provided with filler controlling device 5.Be provided with expulsion valve 6 at combination brake switch and proporting assembly 2 internal upper parts, the bottom is provided with suction valve 7.
The moving direction of expulsion valve 6 suction valves 7 in combination brake switch and proporting assembly 2 is identical with gravitational direction, has greatly improved sealing reliability.
Dismounting combination brake switch and proporting assembly 2 carries out from the upper end of the pump housing 1, and dismounting plunger seal assembly 3 carries out from the front end of the pump housing 1.Both be independent of each other.When regulating filler by being arranged on filler controlling device 5 on the pump housing 1 also at the front end of the pump housing 1.The front end spaces of the pump housing 1 is larger, regulates filler safe and convenient.
