Abstract
The utility model discloses an online efficiency measuring device for a pump. The online efficiency measuring device comprises a pump, a pressure meter, a micro temperature difference meter, an inlet probe component and an outlet probe component, wherein the inlet probe component and the outlet probe component are connected with the micro temperature difference meter through leads respectively; the inlet probe component is inserted into an inlet pipe of the pump; and the outlet probe component is inserted into an outlet pipe of the pump, and is connected with the pressure meter. The utility model has the advantages that: the online efficiency measuring device has a compact structure, an accurate principle and great energy-saving meaning, is easy to online installation; and compared with the national conventional water pump testing device, the online efficiency measuring device is more real and more effective, and can better represent real efficiency.
Description
Technical field
The utility model relates to a kind of water pump, particularly discloses the online efficiency measurement device of a kind of pump.
Background technique
In order to improve the efficient of pump, the continuous abroad higher new pump of design efficiency is updated pump structure, change and developed outstanding hydraulic model energetically, and, built the substantive test device water pump scientific research and manufacturer, testing precision has micron order, firsts and seconds.And formulated the standard of stipulating various big pump efficiency, these work all are the efficient that will improve pump self.But pump one is to site of deployment, during online application, following problem will occur:
1, whether the pump type is applicable to field condition;
2, whether the flow of pump, pressure need be complementary with the scene;
3, whether pump is in best efficiency point work;
4, pump does not have is artificially increased the resistance drop low discharge.
More than these, can sum up in the point that the height of the online efficient of pump, type approval test that pump carries out and delivery test only can detect self efficient of pump, can not detect the online efficient of pump on the manufacturer's trial platform.Also promptly can't solve above-mentioned four problems.
Summary of the invention
The purpose of this utility model is to overcome the defective that exists in the prior art, provide a kind of structure small and exquisite, improve the online efficiency measurement device of pump of the online efficient of pump greatly.
The utility model is achieved in that the online efficiency measurement device of a kind of pump, comprise pump, pressure gauge, it is characterized in that: also comprise tepor difference meter, the inlet probe assembly and the outlet probe assembly that link to each other by lead with tepor difference meter respectively, described inlet probe assembly is inserted in the inlet tube of pump, described outlet probe assembly is inserted in the delivery side of pump pipe, and described outlet probe assembly links to each other with pressure gauge.
Described inlet probe assembly, outlet probe assembly link to each other with inlet tube, the outer pipe of pump with sealing gasket by screw thread respectively.
The beneficial effects of the utility model are: structure is small and exquisite, is easy to online installation, the smart position of principle, energy-saving significance is great, than domestic existing water pump test device, have truer, more effective, more can represent real efficient.
Description of drawings
Fig. 1 is the utility model structural representation.
Wherein: 1, outlet probe assembly; 2, inlet probe assembly; 3, lead; 4, inlet tube; 5, pressure gauge; 6, tepor difference meter; 7, pump; 8, outer pipe.
Embodiment
According to Fig. 1, the utility model comprises pump 7, pressure gauge 5, tepor difference meter 6, the inlet probe assembly 2 and the outlet probe assembly 1 that link to each other by lead 3 with tepor difference meter 6 respectively, described inlet probe assembly 2 is inserted in the inlet tube 4 of pump 7, described outlet probe assembly 1 is inserted in the outer pipe 8 of pump 7, and described outlet probe assembly 1 links to each other with pressure gauge 5.Described inlet probe assembly 2, outlet probe assembly 1 link to each other with inlet tube 4, the outer pipe 8 of pump 7 with sealing gasket by screw thread respectively, and sealing gasket prevents leak of liquid.
The pressure P that tepor difference △ T that is read by tepor difference meter 6 and pressure gauge 3 are read, available following formula calculates the online efficient of pump:
The online efficient of pump=1/ (1+ (426.7 △ Tr/p)), wherein r is a liquid severe.
Claims (2)
