Abstract
The utility model discloses a vertical reciprocating pump piston rod for a ship, which comprises a piston rod and a piston which is fixedly connected with the piston rod. The vertical reciprocating pump piston rod for a ship also comprises a connecting rod. Both ends of the connecting rod are all provided with detachable connecting structures, one end of the connecting rod is connected with the piston rod, and the other end of the connecting rod is connected with a connecting member of a driving mechanism. When the vertical reciprocating pump piston rod for a ship needs to be disassembled, as long as the connecting rod is first disassembled, the driving mechanism is raised to the highest position, and the piston rod and the piston can be taken out. Much trouble when the original disassembly is omitted, and thereby, the vertical reciprocating pump piston rod for a ship brings convenience for daily maintenance and the replacement of wearing members. Therefore, the vertical reciprocating pump piston rod for a ship has artful design, simple measure, and ideal effect. The popularization and the application of the vertical reciprocating pump piston rod for a ship can be anticipated.
Description
The utility model relates to a kind of architecture advances of reciprocating pump member, especially a kind of architecture advances of marine reciprocate pump piston rod.
Existing ship is with the piston rod one end fixed piston in the reciprocating volumetric pump, and the other end directly is connected with connecting rod in the driving mechanism by the link of crosshead and so on.The vertical marine reciprocate pump piston rod of this structure is when dismounting, and the spatial position is limited, must pull down connecting rod, crosshead earlier from top to bottom, could take out piston rod.Because the Sealings such as piston ring on the piston belong to easily damaged parts, need often to change, so the piston rod of existing structure makes the user feel inconvenience deeply when maintaining.
The purpose of this utility model is: problem easily inadequately during at above-mentioned existing piston rod dismounting, proposes a kind of under the constant situation of the former function of maintenance piston rod, the vertical very easily marine reciprocate pump piston rod of dismounting.
In order to achieve the above object, vertical marine reciprocate pump piston rod of the present utility model comprises piston rod and the piston that is connected with it, also comprises extension bar, and the two ends of described extension bar are equipped with the releasable connection structure, the one end is connected with piston rod, and the other end is connected with the link of driving mechanism.
In working order, vertical marine reciprocate pump piston rod of the present utility model is identical with existing piston rod function, therefore can keep the former function of piston rod constant.And when needs are dismantled, as long as pull down extension bar earlier, driving mechanism is risen to the extreme higher position, can take out piston rod and piston, saved the loaded down with trivial details work of original requisite connecting rod of dismounting earlier, crosshead and so on, make disassembling section become very simple and direct, thereby bring great convenience for daily maintaining and the replacing of easily damaged parts.This shows that the utility model is skillfully constructed, measure is simple, satisfactory for result.Can estimate, after applying, will be subjected to the user and welcome.
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is an embodiment's of the utility model a structural representation.
Fig. 2-Fig. 4 is Fig. 1 embodiment's a unloading process schematic representation.
Vertical marine reciprocate pump piston rod among Fig. 1 is by piston rod 1 and the piston 2 that is connected with it, and extension bar 3 is formed, the two ends of extension bar 3 are shaped on internal and external screw thread respectively, and female end is connected with the outside thread of piston rod 1 upper end, and male end is connected with the crosshead 4 of driving mechanism.Threaded connection place, extension bar 3 two ends is all with check nut and tight.2-1 among Fig. 1 is a piston ring.
During use (referring to Fig. 2), piston rod 1 is packed into together with piston 2 in the cylinder body 6, and crosshead 4 is connected with bent axle 5.Its working condition is with originally identical.When needs more during rering 2-1, pull down extension bar 3 (shown in Figure 3) earlier, again bent axle 5 is gone to the extreme higher position, piston rod 1 is screwed in crosshead 4, can take out piston ring 2-1, very convenient.
