Abstract
The utility model discloses a screw motor testing device. The screw motor testing device comprises a water inlet end cap and a water outlet end cap which are respectively arranged at two ends of a motor casing; a motor rotor is arranged in the motor casing; replaceable rubber sealing pieces are respectively arranged between the inner lateral surfaces of both the water inlet end cap and the water outlet end cap and the out edge surface of the motor casing; and a universal joint connected with and driving the motor rotor is also arranged at the water inlet end cap. According to the screw motor testing deice, the test assembly process of the screw motor is simple, the production efficiency is high, the installation of the screw motor is easy, and the screw motor is difficult to damage.
Description
Technical field
The utility model relates to a kind of screw motor test unit.
Background technology
During the screw motor test, mainly lean on motor case and being threaded of plug to play sealing effectiveness.Every motor is before making an experiment, and needing also needs after test is accomplished to thread screw on and-off machine, screw thread is unloaded making an experiment after with screwed on the thread screw on and-off machine again, and the test assembly process is loaded down with trivial details, produce render a service low.The motor of the different size plug that then need be equipped with corresponding different size that makes an experiment connects use.When the motor of specification carries out the motor test relatively, different because of connecting thread, also need dispose different plugs and connect, increased experimentation cost.And after motor unloaded on carrying out once, damaging and the underproof situation of thread parameter often appearred in connecting thread, produced unnecessary substandard products, caused unnecessary economic loss.
The utility model content
The technical matters that the utility model will solve is: overcome the deficiency in the prior art, provide that a kind of test assembly process is simple, production efficiency is high, not the screw motor test unit of motor damage.
The utility model solves the technical scheme that its technical matters adopted: a kind of screw motor test unit; Comprise the water inlet plug, the water outlet plug that are separately positioned on the motor case two ends; Motor rotor is arranged in the motor case; Be respectively equipped with removable caulking gum spare between the medial surface of water inlet plug and water outlet plug and motor case outer edge surface, described water inlet plug end also is provided with the universal joint that is connected and drives the motor rotor rotation with motor rotor.
Caulking gum spare is the nitrile rubber O-ring seal.
The beneficial effect of the utility model is: the screw motor test unit that the utility model provides connects plug and test motor through removable caulking gum spare, and motor test assembly process is simple, production efficiency is high, and the test motor is installed simply and easy damaged not.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Fig. 1 is the structural representation of the utility model.
1. motor cases, 2. water inlet plugs, 3. water outlet plugs, 4. motor rotors, 5. caulking gum spares, 6. universal joints among the figure
Embodiment
Combine accompanying drawing that the utility model is further described now.The synoptic diagram that these accompanying drawings are simplification is only explained the basic structure of the utility model in a schematic way, so it only shows the formation relevant with the utility model.
A kind of screw motor test unit as shown in Figure 1 comprises the water inlet plug 2, the water outlet plug 3 that are separately positioned on motor case 1 two ends, and motor rotor 4 is arranged in the motor case 1.Be respectively equipped with removable caulking gum spare 5 between the medial surface of water inlet plug 2 and water outlet plug 3 and motor case 1 outer edge surface, caulking gum spare 5 is the nitrile rubber O-ring seal.Water inlet plug 2 ends also are provided with the universal joint 6 that is connected and drives motor rotor 4 rotations with motor rotor 4.The other end of universal joint then connects testing machine.
At the trial; The universal joint 6 that one end connects testing machine drives motor rotor 4 rotations, because the swabbing action of screw motor, circulating fluid is inhaled into from the gap location of water inlet plug 2; The sealed chamber that process motor rotor 4 and motor case are 1 discharges from water outlet plug 3.When the screw motor of test plurality of specifications, can design as required and produce the water inlet plug 2 and water outlet plug 3 that can assemble maximum specification test motor.At the trial, water inlet plug 2 is constant with water outlet plug 3, and is different according to test motor specification, changes the caulking gum spare 5 of different size, after will test motor and assembling with water inlet plug 2 and water outlet plug 3, can normally test.Like this motor test unit of design, assembly process is simple, production efficiency is high, and the test motor is installed simply and easy damaged not.
Above-mentioned embodiment is only for explaining the technical conceive and the characteristics of the utility model; Its purpose is to let the personage that is familiar with this technology can understand the content of the utility model and implements; Can not limit the protection domain of the utility model with this; All equivalences of being done according to the utility model spirit change or modify, and all should be encompassed in the protection domain of the utility model.
