Description
Technical field
The utility model relates to test device field, in particular to a kind of water pump test macro.
Background technique
Water pump is in New Product Development Process at present, it is necessary to the properties of continuous test water pump, thus targetedly
Product is constantly improved.
But in the prior art, lack corresponding testing water pump device, and general test macro does not measure water
The function of cavitation of pump.
Utility model content
The technical problem to be solved by the present invention is to provide the test macros that one kind can test pump cavitation surplus.
In order to solve the above-mentioned technical problem, the technical solution of the utility model is：
A kind of water pump test macro, including test pipeline, water pump are mounted on the test pipeline；
Gate valve in water is installed in the test pipeline inlet；
The water pump inlet is equipped with inlet pressure sensor；
The water pump water outlet end is equipped with outlet pressure sensor；
Ground gate valve is also equipped on the test pipeline；
The water inlet end of the ground gate valve is equipped with turbine flowmeter；
The water pump test macro further includes the data cabinet for receiving and processing test signal.
Preferably, speed probe is installed on the pump motor.
By adopting the above technical scheme, test device whole design structure is simple, and has the function of test pump cavitation surplus
Can, the performance detection of water pump can be conveniently used for.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
In figure：1- tests pipeline, 2- water pump, gate valve in 3- water, 4- inlet pressure sensor, 5- outlet pressure sensor,
The ground 6- gate valve, 7- data cabinet, 8- turbine flowmeter, 9- speed probe.
Specific embodiment
Specific embodiment of the present utility model is described further with reference to the accompanying drawing.It should be noted that
The explanation of these embodiments is used to help to understand the utility model, but does not constitute the restriction to the utility model.This
Outside, technical characteristic involved in the various embodiments of the present invention described below is as long as they do not conflict with each other
It can be combined with each other.
As shown in Figure 1, a kind of water pump test macro, including test pipeline 1, test pipeline 1 are passed through at both ends in test
In pond.Water pump 2 to be tested is mounted on testing tube 1, is equipped with gate valve 3 in water in test 1 inlet of pipeline；Gate valve in water
3 can control 1 inflow of testing tube.2 water inlet end of water pump is equipped with inlet pressure sensor 4, for testing 2 water inlet of water pump
Pressure value；2 water outlet of water pump is equipped with outlet pressure sensor 5, for testing the pressure value of 2 water outlet of water pump.Test pipeline 1
On be also equipped with ground gate valve 6, ground gate valve 6 can control water flow in test pipeline 1；The water inlet end of ground gate valve 6 is pacified
Equipped with turbine flowmeter 8, for testing water flow value in test pipeline.This test macro further includes receiving and processing test letter
Number data cabinet 7, for the signal that receiving sensor detects, using signal processing software will test data be converted into but figure
Table.
Wherein, speed probe 9 is installed on 2 motor of water pump, for detecting the revolving speed of motor on water pump 2.
Working principle：Control 6 switch size of ground gate valve can control the flow of water pump 2, and 2 flow of water pump and lift are at anti-
Than flow is bigger, and lift is lower, and the size switched by control ground gate valve 6 can test water pump 2 in different flow repeatedly
When lift.The data tested out are transferred in data cabinet 7 by data line, are converted to viewdata by signal processing software
And 2 performance chart of water pump, to obtain the performance and stability of water outlet pump 2.
3 switch size of gate valve can control 2 inlet pressure of water pump in control water, can be with until cavitation phenomenons occurs in water pump 2
Net positive suction head of the test water pump 2 in different inlet pressures repeatedly.The data tested out are transferred to data cabinet 7 by data line
In, 2 net positive suction head curve graph of viewdata and water pump is converted to by signal processing software, to obtain the net positive suction head of water outlet pump 2
Performance.
The embodiments of the present invention is explained in detail in conjunction with attached drawing above, but the utility model is not limited to be retouched
The embodiment stated.For a person skilled in the art, right in the case where not departing from the utility model principle and spirit
These embodiments carry out a variety of change, modification, replacement and modification, still fall in the protection scope of the utility model.
