Abstract
The utility model discloses a simple structure's fluid end device of motor-driven reciprocating pump, its structure of flowing in and flowing back valves comprises spring, case, the three subassembly of disk seat, adopts the tapering to grind and closes between the disk seat and the pump body, and the flange adopts big threaded connection. The utility model discloses simple structure, spare part quantity reduction, processing require low, the dismouting maintenance is simple and convenient, and pump valve leakproofness improves to some extent to reduced and pressed cover and relevant sealing member, maintenance convenient and fast more.
Description
Technical field
The utility model relates to the correlative technology field of automotive reciprocating pump, particularly relates to a kind of fluid end device of automotive reciprocating pump.
Background technique
At present, existing automotive reciprocating pump fluid end device is by combination valve 17 ' and 18 ', gland 12 and 13, upper-lower seal 14 and component such as 15 are formed up and down.It exists following shortcoming: at first, traditional combination valve group 17 ' and 18 ' comprises gland 1, locking nut 2, nut 3, pad 4, locker 5, valve rod 6, spring 7 ', valve plate 8, pin 9, valve seat 10 ', complex structure, component are various, and the dismounting maintenance is complicated; Secondly, because this device is worked under hyperbaric environment for a long time, sealing 14 and 15 damages easily, cause gland 12 and 13 transmissions up and down, thereby cause the valve seat 10 ' of combination valve 17 ' and 18 ', up and down gland 12 and 13 the cracking, finally cause the pump housing 16 ' also crackle can occur, so rate of fault is higher, utilization efficiency is lower, and sealing is changed frequent; Once more, flange adopts bolt directly fastening, during maintain and replace valve group, four bolts all need be disassembled, and bolt is long-term autonomous in hyperbaric environment, and bolt ruptures because of tired easily during dismounting, and the pump housing is scrapped.
The model utility content
The purpose of this utility model provides a kind of fluid end device of automotive reciprocating pump simple in structure, has solved complex structure, problems such as the rapid wear assembly is many, processing request is high, dismounting trouble, labor strength is big, working life is short that traditional automotive reciprocating pump fluid end exists.
For realizing above-mentioned model utility purpose, the technical solution adopted in the utility model is as follows:
The utility model discloses a kind of fluid end device of automotive reciprocating pump, comprise the pump housing, pump housing inlet/outlet is with combination valve group, spring seat, upper-lower seal, flange successively, it is characterized in that, combination valve group 17 and 18 comprises spring 7, spool 11, valve seat 10; Adopt the tapering grinding seal between combination valve group 17 and 18 valve seat 10 and the pump housing 16; Flange 19 adopts major thread to connect.
Described combination valve group 17 and 18 adopts conical valve from leading structure.
The beneficial effects of the utility model are that the combination valve group is simple in structure, amount of parts reduces, processing request is low, the dismounting maintenance is easy; The pump valve sealing increases, and has reduced gland and associated seal, maintains more convenient; Only the flange gland need be pulled down during the dismounting of pump housing flange and get final product, easy and simple to handle, reduced the quantity in stock of labor strength and spare part effectively, increase work efficiency and prolonged working life of the pump housing.The data on probation that come into operation in certain company after (the pressure 32MPa of pump moves 5 months continuously, moves every day more than 20 hours) are as follows:
The working efficiency of reciprocating pump has improved 8%;
The stopping production maintenance time has reduced 80%;
The fragile part life-span prolongs 100%～200%;
Maintenance cost reduces by 60%.

Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Referring to Fig. 1, Fig. 2, the utility model combination valve group 17 and 18 structure are made of spring 7, spool 11,10 3 assemblies of valve seat, compare with old-fashioned valve block structure shown in Figure 1, reached simplified structure, have reduced number of spare parts, the easy purpose of dismounting.
Described combination valve group 17 and 18 adopts conical valve from leading structure.
Referring to Fig. 3, Fig. 4, adopt the tapering lapping-in between the combination valve group 17 of the new shape of this practicality and 18 the valve seat 10 and the pump housing 16; Flange 19 adopts major thread to connect.
Claims (2)
