Abstract
The utility model discloses a water pump lift test device comprising a three-way pipe. One end of the three-way pipe is a water inlet end which is connected to a water outlet of a water pump; the other two ends of the three-way pipe are a first water outlet end and a second water outlet end which are provided with a pressure gauge and a brake valve respectively. The water pump lift test device is simple in structure, enables people to simply judge whether the phenomenon of insufficient lift is caused by the failure of the pump, provides evidence for the maintenance of the water pump and reduces waste of water resources.
Description
Technical field
The utility model relates to a kind of pump head testing apparatus.
Background technique
Flame-proof type submersible sand discharging pump is coal mine drainage facility important component part, is to guarantee one of safety in production key factor, directly has influence on the safety in production in colliery.Flame-proof type submersible sand discharging pump is used comparatively frequent in mine, so damage, is more also frequent, often occurs the phenomenon that lift is inadequate.
Model utility content
The purpose of this utility model is to provide a kind of pump head testing apparatus, simply judges whether because the failure cause of water pump own causes, to reduce the waste of water resources.
The technical solution of the utility model is as follows:
A kind of pump head testing apparatus, it is characterized in that: include three-way pipe, one end of described three-way pipe is feed-water end, described feed-water end is connected to the water outlet of water pump, another two ends of described three-way pipe are respectively first and second waterexit end, and first and second described waterexit end is separately installed with pressure gauge and gate valve.
Described pump head testing apparatus, is characterized in that: the outside of described feed-water end is provided with flange.
The beneficial effects of the utility model:
The utility model is simple in structure, can simply judge that whether the generation of the inadequate phenomenon of lift is because the failure cause of pump own causes, and for the maintenance of water pump provides foundation, has reduced the waste of water resources.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Embodiment
Referring to Fig. 1, a kind of pump head testing apparatus, includes three-way pipe 1, one end of three-way pipe 1 is feed-water end 2, feed-water end 2 is connected to the water outlet of water pump, and another two ends of three-way pipe 1 are respectively first and second waterexit end 3,4, and first and second waterexit end 3,4 is separately installed with pressure gauge 5 and gate valve 6.
In the utility model, the outside of feed-water end 2 is provided with flange 7, to facilitate with the water outlet of water pump, is connected.
Below in conjunction with accompanying drawing, the utility model is further described:
Water lift of pump is called again water pump head, refers to the energy that monomer weight fluid obtains through water pump.
Water lift of pump can be measured by following methods, water outlet at water pump is installed vacuum gauge, the first waterexit end 3 at three-way pipe 1 is provided with pressure gauge 5, the pressure of the first waterexit end 3 of three-way pipe 1 is equal to the pressure of the water intake of water pump, if the kinetic energy of disregarding on two table cross sections is poor, disregard the energy loss between two table cross sections, water lift of pump can calculate with following formula: H=h
0+ (p
2-p
1)/ρ g
In formula, h
0for the perpendicular distance between water pump entery and delivery port, unit is m, the density that ρ is water, and g is gravity accleration, unit is m/s
2, p
2for the reading of pressure gauge 5, unit is Pa; p
1for the reading of the water intake vacuum gauge of water pump, unit is Pa, due to p
1numerical value less, therefore can ignore.
The setting value lift of supposing water pump is 100m, and recording flow is 50m
3during/h, the pressure of pump intake is ignored, and the reading of pressure gauge 5 is 0.9Mpa, and the perpendicular distance between known water pump entery and delivery port is 1.08m, in the time of 20 ℃, and the density p=988.2kg/m of water
3, the actual lift that calculates this water pump is: H=1.08+9*10
5/ 988.2*9.81=93.88m, because measurement exists error, so the data of surveying are slightly less than setting value.
Claims (2)
1. a pump head testing apparatus, it is characterized in that: include three-way pipe, one end of described three-way pipe is feed-water end, described feed-water end is connected to the water outlet of water pump, another two ends of described three-way pipe are respectively first and second waterexit end, and first and second described waterexit end is separately installed with pressure gauge and gate valve.
2. pump head testing apparatus according to claim 1, is characterized in that: the outside of described feed-water end is provided with flange.
