Abstract
The invention discloses a placement tool for gear pumps. The placement tool provided by the invention comprises an external frame and is characterized in that the placement tool also comprises an internal frame, which is disposed inside the external frame; a connection hole is disposed between and respectively connected through the internal frame and the external frame; and the external and internal frames are circular frames or elliptical frames and are made from a corrosion-resistant material. In the prior art, as gear pumps have no good protection tool, internal parts of the gear pumps are easy to corrode and damage so that the gear pumps have short service life and need to be frequently replaced and maintained. Therefore, the usage cost is increased. The placement tool for gear pumps in the invention can be used to solve the above problems in the prior art. The invention provides the placement tool, which has a simple structure, is convenient to use and has a good function of protecting gear pumps.
Description
Technical field
The present invention relates to the frock technical field, particularly relate to a kind of gear pump and place frock.
Background technique
Two or more gears that gear pump relies on, the working space volume-variation that in the process of being meshing with each other, is produced is carried the pump of liquid.When gear rotated, the volume in the space of the side that is out of gear was big from little change, formed vacuum, and liquid is sucked, and the volume in the space of gear engagement side is from diminishing greatly, went and liquid clamp-oned in the pipeline.Suction chamber and discharge side separate by two gear meshing lines.The pressure of the exhaust port of gear pump depends on the size that pumps place's resistance fully.
Present gear pump does not have the better protect frock; Through using for a long time, inner part very receives corrosion and damage easily, has brought bigger restriction for so the normal use of gear pump; Inner part is shorter working life; Need frequent repair and replacement, increased user cost, brought unnecessary burden to the user.
Summary of the invention
There is not the better protect frock in order to solve existing technology middle gear pump; Inner part very receives corrosion and damage easily, and working life is shorter, needs frequent repair and replacement; Increased the problem of user cost; The invention provides a kind of simple in structurely, easy to use, can place frock the gear pump that gear pump play better protective action.
In order to address the above problem, the technological scheme that the present invention taked is:
A kind of gear pump is placed frock, comprises housing, it is characterized in that: also comprise inside casing, in the set inside of housing inside casing is arranged, between inside casing and housing, be provided with respectively and connect the attachment hole that is connected with the two.
Aforesaid a kind of gear pump is placed frock, it is characterized in that: said housing and inside casing adopt circular frame.
Aforesaid a kind of gear pump is placed frock, it is characterized in that: said housing and inside casing adopt oval frame.
Aforesaid a kind of gear pump is placed frock, it is characterized in that: said housing and inside casing adopt resistant material to process.
The invention has the beneficial effects as follows: gear pump of the present invention is placed frock and can be protected gear pump integral body, prevents that the gear pump inner body from being corroded, like this working life of gear pump just longer, reduced the user cost of gear pump.
Description of drawings
Fig. 1 is that gear pump of the present invention is placed the tool structure schematic representation.
Fig. 2 is the generalized section that gear pump of the present invention is placed frock.
Embodiment
Below in conjunction with accompanying drawing the present invention is done further description.
Shown in Fig. 1-2, a kind of gear pump is placed frock, comprises housing 1 and inside casing 2, in the set inside of housing 1 inside casing 2 is arranged, and between inside casing 2 and housing 1, is provided with respectively and connects the attachment hole 3 that is connected with the two.During design, housing 1 adopts circular frame or oval frame with inside casing 2, and housing 1 uses resistant material to process with inside casing 2.
The main frame of gear pump is placed in the inside casing 2; Main shaft can stretch out through attachment hole 3; The housing 1 of placing frock through gear pump carries out duplicate protection with 2 pairs of gear pumps of inside casing; The gear pump inner body can not corroded, and the working life of gear pump is just longer, and the use maintenance cost of gear pump has also obtained reducing greatly.
More than show and described basic principle of the present invention, major character and advantage.The technician of the industry should understand; The present invention is not restricted to the described embodiments; That describes in the foregoing description and the specification just explains principle of the present invention; Under the prerequisite that does not break away from spirit and scope of the invention, the present invention also has various changes and modifications, and these variations and improvement all fall in the scope of the invention that requires protection.The present invention requires protection domain to be defined by appending claims and equivalent thereof.
Claims (4)
1. a gear pump is placed frock, comprises housing, it is characterized in that: also comprise inside casing, in the set inside of housing inside casing is arranged, between inside casing and housing, be provided with respectively and connect the attachment hole that is connected with the two.
