Abstract
A minitype manual filling device for centrifugal pump comprises a centrifugal pump (1), wherein the front end of a water outlet of the centrifugal pump (1) is provided with a brake valve (3); a blast pipe of the centrifugal pump is connected with a manual hand-pressed well nose (2) which consists of a barrel (8), a bottom valve (4), a piston (7), a pressing handle (5) and a support frame (6). The utility model has the advantages of high efficiency, low investment, convenient use, time and power conservation, etc.
Description
One, technical field
The utility model relates to a kind of water conservancy equipment, the manual filling device of specifically small-sized centrifugal pump.
Two, background technique
When the centrifugal pump setting height(from bottom) is higher than the water inlet pool water level, before startup, must be full of water in the intake pipe and the pump housing, its water-filling method is more, small pumping station mainly adopts the water inlet artificial water-filling of pipe racks bottom valve and is not with bottom valve vacuum box water-filling dual mode at present, the artificial water-filling of water inlet pipe racks bottom valve is a water-filling mode the most original, that application is the most general, the operation of water pump band bottom valve can increase the loss of pipeline tube head, reduces the efficient of device, strengthen the water lift cost, the water that causes the bottom valve bad sealing for various reasons and charge into when leaking can be with filling with leakage time-consuming effort again.Use the vacuum box water-filling,, have the advantage that starts at any time though remove bottom valve, but because vacuum tube is installed on the pipeline, loss of head does not reduce, because of vacuum chamber bigger, only be applicable to fixed pump station, and the steel plate making that vacuum box need be thicker, price is higher to be restricted in actual applications.
Three, summary of the invention
The utility model is at above deficiency, and the manual filling device of small-sized centrifugal pump of a kind of efficient height, little investment, easy to use, the province's merit that saves time is provided.
The technological scheme that its technical problem that solves the utility model adopts is: the manual filling device of a kind of small-sized centrifugal pump, comprise centrifugal pump, be connected with manual hand well head on the exhaust tube of centrifugal pump, this hand well head is made up of cylindrical shell, bottom valve, piston, pressure handle, supporting frame etc.
The gate valve of centrifugal pump front end setting can be closed the water outlet of centrifugal pump, makes it form an airtight environment that is similar to the hand well, and inwardly water filling just can be to the centrifugal pump water-filling under the situation that gate valve is closed for the hand well head of setting.
Four, description of drawings
Fig. 1 is the structural representation of a kind of mode of execution of the utility model;
Fig. 2 is the structural representation of hand well head.
Five, embodiment
As shown in Figure 1, the 1st, centrifugal pump, the 2nd, hand well head, the 3rd, gate valve, the 4th, bottom valve, the 5th, pressure handle, the 6th, supporting frame, the 7th, piston, the 8th, cylindrical shell.
The manual filling device of a kind of small-sized centrifugal pump comprises centrifugal pump 1, at the water outlet front end of centrifugal pump 1 gate valve 3 is installed; Be connected with manual hand well head 2 on the exhaust tube of centrifugal pump 1, this hand well head 2 is made up of cylindrical shell 8, bottom valve 4, piston 7, pressure handle 5, supporting frame 6.
Gate valve 3 is closed, in hand well head 2, pour a little diversion, push the pressure handle 5 of filling device repeatedly, in whole cylindrical shell, be full of water, air all emptyings when almost overflowing in explanation intake pipe and the pump case, open gate valve 3 this moment, just can start the power equipment water lift.Water pump assembly must lift the pressure handle 5 of filling device so that bottom valve 4 cuts out after running well, and prevents that the water in the pump housing from flowing out from cylindrical shell 8.
Claims (1)
1, the manual filling device of a kind of small-sized centrifugal pump comprises centrifugal pump (1), it is characterized in that: the water outlet front end at centrifugal pump (1) is equipped with gate valve (3); On the exhaust tube of centrifugal pump, be connected with manual hand well head (2); This hand well head (2) is made up of cylindrical shell (8), bottom valve (4), piston (7), pressure handle (5), supporting frame (6).
