Description of the drawings
Fig. 1 is a kind of structural schematic diagram of horizontal centrifugal self priming pump of the utility model.
In figure, 1. centrifugal pump of horizontal axis, 2. feed liquor check valves, 3. gas-liquid separation chamber, 4. charging valves, 5. make-up valves, 6. pipelines,
7. inlet tube.
Specific implementation mode
The utility model is described in detail with reference to the accompanying drawings and detailed description.
A kind of horizontal centrifugal self priming pump of the utility model, including centrifugal pump of horizontal axis 1, the connection of 1 entrance of centrifugal pump of horizontal axis
There is inlet tube 7, the feed liquor check valve 2 for preventing medium from flowing backwards is installed on inlet tube 7, the outlet of centrifugal pump of horizontal axis 1, which is equipped with, to be convenient for
The gas-liquid separation chamber 3 of gas-liquid mixture separation, 3 top of gas-liquid separation chamber are equipped with the charging valve 4 for adding medium, gas-liquid point
It is also connect with the import of centrifugal pump of horizontal axis 1 by pipeline 6 from room 3, make-up valve 5 is provided on pipeline 6.
Charging valve 4 is mounted on 3 top of gas-liquid separation chamber and the position of the top plate higher than gas-liquid separation chamber 3, charging valve installation
At the top of gas-liquid separation chamber, it is higher than gas-liquid separation chamber's top plate, is full of liquid in pump chamber and gas-liquid separation room when ensureing liquid feeding.
6 one end of pipeline is connected to gas-liquid separation chamber 3 bottom, and the other end is connected to 1 import of centrifugal pump of horizontal axis and feed liquor is unidirectional
On inlet tube 7 between valve 2.
3 bottom of gas-liquid separation chamber is connected to by pipeline 6 with the inlet tube 7 after feed liquor individual event valve, and fluid infusion is installed among pipeline 6
Valve 5, liquid in inlet pipeline exhaust process in gas-liquid separation chamber 3 by make-up valve enter centrifugal pump of horizontal axis 1 due to gravity
Pump chamber ensures that exhaust process is accomplished, and make-up valve 5 is closed after centrifugal pump of horizontal axis 1 exports out liquid, to ensure pump discharge just
Often.Feed liquor individual event valve is mounted on pump inlet, and under vacuum and gravity, feed liquor check valve either on or off completes pump inlet pipe
The exhaust process in road.
Gas-liquid separation chamber 3 is mounted on the outlet of centrifugal pump of horizontal axis 1, and main function is by the gas separation in gas liquid mixture
Out it is discharged.The volume of gas-liquid separation chamber 3 is greater than the volume of pump chamber, generally twice or more in pump chamber volume, before pump is opened
It must be by charging valve to inside it plus water.
The operation principle of the utility model is：The front opening make-up valve 5 of 1 startup of centrifugal pump of horizontal axis opens charging valve 4 to sleeping
The pump chamber of formula centrifugal pump 1 and gas-liquid separation chamber 3 fill water, are then shut off charging valve 4.After centrifugal pump of horizontal axis 1 starts, due to horizontal
Liquid in 1 pump chamber of centrifugal pump is pressed into gas-liquid separation chamber 3, and pump chamber forms vacuum state, work of the feed liquor check valve 2 due to negative pressure
With opening, the air in pump inlet pipeline 6 enters pump chamber by feed liquor individual event valve 2, and the negative pressure state in pump chamber is broken, feed liquor
Check valve 2 is closed, and the liquid in gas-liquid separation chamber 3 is back to pump chamber and the gas mixing in pump chamber through make-up valve 5, in centrifugal force
Under the action of gas liquid mixture be pressed into gas-liquid separation chamber 3, gas liquid mixture enters the gas-liquid separation chamber that volume increased dramatically, by
Detached with liquid in gravity gas, gas is discharged by pump discharge, and pump chamber forms vacuum state again, pump repeatedly into
Air in mouthful is drained, and liquid is flowed out from pump discharge, closes make-up valve, and pump runs well.
