Abstract
The utility model discloses a kind of automatic water diversion devices for centrifugal pump, it includes vacuum tank, and the vacuum tank is connected with the water inlet of external water inlet line and the centrifugal pump respectively.The utility model can achieve the purpose that automatic water-leading, and structure is simple, save cost when starting centrifugal pump.
Description
Technical field
The utility model relates to a kind of automatic water diversion devices for centrifugal pump.
Background technique
Before being centrifuged pump startup, the first step is all diversion appropriate to be first added into pump, or utilize vacuum pump on pipeline
Carry out air-discharging operation, the start-up operation then just pumped.Make that the method for diversion is added to start centrifugal pump if it is benefit, then
Water inlet front end just needs to install additional bottom valve, then mating tank priming device just can be used, and sometimes due to bottom valve quality
Difference leads to not normally start centrifugal pump there are water leakage situation, and when maintenance need to carry out dismounting lifting etc., maintenance difficult.Using
Vacuum pump air-discharging operation starting water pump, this mode input cost are big.
Summary of the invention
Technical problem to be solved in the utility model is to overcome the deficiencies of existing technologies, and is provided a kind of for centrifugal pump
Automatic water diversion device, it can achieve the purpose that automatic water-leading, and structure is simple, save cost when starting centrifugal pump.
In order to solve the above-mentioned technical problem, the technical solution of the utility model is: a kind of automatic water-leading for centrifugal pump
Device, it includes vacuum tank, and the vacuum tank is connected with the water inlet of external water inlet line and the centrifugal pump respectively.
Further, vacuum tank is stated with inlet and outlet, the import of the vacuum tank is connected with external water inlet line,
The outlet of the vacuum tank is connected with the water inlet of the centrifugal pump.
Further for the connection for the outlet for facilitating vacuum tank and external water inlet line and centrifugal pump, the vacuum tank
Inlet and outlet is respectively connected with flange.
Further for water is entered preferably in vacuum tank, suction hose, the vacuum are provided in the vacuum tank
The inlet and outlet of tank is arranged at the lower end of vacuum tank, and the import of vacuum tank described in one end of the suction hose is connected,
The other end of the suction hose extends to the upper end of vacuum tank.
Further, the water outlet of the centrifugal pump is connected with valve.
Further for preferably diversion, the volume of the vacuum tank is L1, and the volume of the centrifugal pump and valve is L2,
External water inlet line is L3 along Cheng Rongji, and wherein L1 is 1.5~2 times of the sum of L2 and L3.
Further, the suction hose includes the first elbow being sequentially communicated, straight sections and the second elbow, first elbow
It is connected with the import of the centrifugal pump.
Further, the upper end of the vacuum tank has been located at water filling port, and the water filling port is equipped with manual ball valve.
After above-mentioned technical proposal, the utility model is connected vacuum between centrifugal pump and the water inlet line of outside
Tank avoids so that the utility model can achieve the purpose that automatic water-leading when starting centrifugal pump and is opening centrifugal pump
The operation for adding diversion in forward centrifugal pump, also saves vacuum pump, gas water separation tank and bottom valve etc., and structure is simple, reduces
Use cost provides economic benefit.
