Abstract
The utility model discloses a kind of mechanical seal for pump erecting tools, belong to mechanical seal field.This mechanical seal comprises roller, table top, is provided with four symmetrical pillars and push rod, is provided with the pedal of cylinder and the control cylinder coordinated with push rod below table top above table top; Be provided with internal concave hopper chute in the middle of described pillar, and the slide block with chute adaptation is installed on pillar; Described slide block is welded with support bar, and the stiff end bottom of support bar is connected with push rod, and support bar free end is provided with holddown groove.Adopt the utility model that mechanical seal for pump is installed easier, safety, avoids the damage that sealing pair produces because of collision.
Description
Technical field
The utility model relates to mechanical seal field, specifically a kind of mechanical seal for pump erecting tools.
Background technology
Mechanical seal (mechanical seal) refers to and under the effect of fluid pressure and compensation mechanism elastic force (or magnetic force) and under the cooperation of auxiliary seal, keeps laminating by least one pair of end face perpendicular to rotation and relative sliding and device that the anti-fluid that forms is leaked.
At current water pump of the prior art mostly by machine shaft Direct driver, this just needs to install mechanically-sealing apparatus between the rotating shaft and the pump housing of motor.And in a pair sealing pair of general mechanical seal, rotating ring relatively rotates with rotating shaft, formed between stationary ring with rotating ring end face and abut pressure initiation and seal.
When installing mechanical seal, Chang Yinwei mechanical seal is heavy, and workman exerts a force inequality, and operate miss, cause sealing pair and pump shaft to collide, sealing pair is damaged, and sealing property weakens.
Utility model content
The utility model aims to provide a kind of mechanical seal for pump erecting tools, is intended to make mechanical seal more accurate, convenient, fast when mounted, avoids the damage that sealing pair produces because of collision simultaneously.
For achieving the above object, the technical solution of the utility model is as follows:
A kind of mechanical seal for pump erecting tools, comprises roller, table top, it is characterized in that: be provided with four symmetrical pillars and push rod above table top, be provided with the pedal of cylinder and the control cylinder coordinated with push rod below table top; Be provided with internal concave hopper chute in the middle of described pillar, and the slide block with chute adaptation is installed on pillar; Described slide block is welded with support bar, and the stiff end bottom of support bar is connected with push rod, and support bar free end is provided with holddown groove.
Further, described pillar is detachable, with being threaded on table top.
Further, described support bar is the expansion link of length adjustable.
The beneficial effects of the utility model are:
Be placed on after in holddown groove by mechanical seal connecting screw rod, adopt the transmission of pedal control cylinder, cylinder drives push rod to rise, and freely controls the height of support bar on pillar by slide block, machine is sealed and reaches setting height(from bottom), time saving and energy saving.Heavy mechanical seal for pump carried on carry off without workman's gas that goes to great pains again, it also avoid error when mounted simultaneously and causing machine to seal to drop and injure the situation of workman by a crashing object.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of a kind of mechanical seal for pump erecting tools that the utility model provides.
Mark in figure: 1 be roller, 2 be table top, 3 be pillar, 4 be slide block, 5 be support bar, 6 be holddown groove, 7 be push rod, 8 be cylinder, 9 for pedal.
Detailed description of the invention
Below in conjunction with accompanying drawing and specific embodiment, the utility model is described further.
As shown in Figure 1, a kind of mechanical seal for pump erecting tools, comprise roller 1, table top 2, it is characterized in that: be provided with four symmetrical pillars 3 and push rod 7 above table top 2, below table top 2, be provided with the pedal 9 of the cylinder 8 and control cylinder 8 coordinated with push rod 7; Described pillar 3 is detachable, with being threaded on table top 2; Be provided with internal concave hopper chute in the middle of pillar 3, and the slide block 4 with chute adaptation is installed on pillar; Described slide block 4 is welded with support bar 5, and support bar 5 is the expansion link of length adjustable, and the stiff end bottom of support bar 5 is connected with push rod 7, and support bar 5 free end is provided with holddown groove 6.
In use, first by the through hole that the connecting screw rod that two are sealed on pump for fixing machine is sealed up through machine, then after the two ends of connecting screw rod are placed in holddown groove 6 internal fixtion respectively, step on pedal 9, band dynamic air cylinder 8 works, and push rod is propped up and moved upward by cylinder 8.Now, push rod promotes support bar 5 upwards, and slide block 4 prolongs chute and moves upward, and takes up machine envelope and reaches prepackage height, then promote erecting tools and install near pump shaft.
After adopting the utility model, when mounted, after aiming at pump shaft, machine envelope does not teetertotter, workman only need exert a force by machine envelope push in pump shaft and can complete installation, avoid sealing pair when teetertottering collide with pump shaft damage, more laborsaving, safety is installed simultaneously, it also avoid error when mounted and causing machine to seal to drop and injure the situation of workman by a crashing object.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
