Abstract
The utility model discloses a balancing drum of a multi-stage pump. A key slot is formed on the inner side wall of a balancing drum of the multi-stage pump, wherein gasket grooves are formed at a rear port and a rear port of the balancing drum of the multi-stage pump, a multi-thread mounting hole is formed on the rear end surface of the balancing drum of the multi-stage pump, and a continuous groove is formed on the outer side wall of the balancing drum of the multi-stage pump. The balancing drum ensures the safe and reliable operation of the equipment, enhances the throttling effect, reduces the shaft power of the pump and also improves the pump efficiency.
Description
Technical field
The utility model throttle structure is applicable to the colliery multistage pump, among the balancing drum device of boiler feed pump etc.
Background technique
In the colliery, field such as iron ore, chemical industry, power station is being extensive use of multistage centrifugal pump.Horizontal in the market, MODEL VERTICAL MULTISTAGE PUMP, its great majority adopt Balance disc, balancing drum and dish drum structure.Its equilibrium principle produces pressure reduction work by throttling.If but reduce radial clearance in order to improve pressure reduction, and wait can for like this assembling and bring very big difficulty, but also break down easily, cause equipment normally not move.If the increase radial clearance has just reduced the efficient of pump, additive decrementation the power of motor.
The model utility content
The utility model provides that a kind of restriction effect is higher, operation balancing drum more stably.
The utility model technical solution problem provides following scheme:
A kind of multistage pump balancing drum, described multistage pump balancing drum madial wall is provided with keyway, former and later two ports of described multistage pump balancing drum all are provided with gasket groove, establish many threaded mounting holes on the ear end face of described multistage pump balancing drum, have continuous groove on the outer side wall of described multistage pump balancing drum.
The cross section of described groove is a rectangle.
In the gasket groove of described multistage pump balancing drum rear end seal ring is set.
The beneficial effects of the utility model are:
Balancing drum is as the multistage pump vitals, and balance is by the axial force of the asymmetric generation of impeller front and rear cover plate.The axial force that water pump the time can produce in operation after the balancing drum balance, is eliminated or is diminished affacting axial force on the bearing, thereby increased the working life of bearing.Guarantee the safe and stable operation of equipment.Improve restriction effect, reduced the air horsepower of pump, also improved the efficient of pump simultaneously.
Description of drawings
Fig. 1 is the utility model balancing drum structure assembling back schematic representation.
Fig. 2 is the utility model balancing drum structural representation.
Embodiment
Referring to accompanying drawing, a kind of multistage pump balancing drum, described multistage pump balancing drum 1 madial wall is provided with keyway 2, former and later two ports of described multistage pump balancing drum 1 all are provided with gasket groove 3,4, establish many threaded mounting holes 5 on the ear end face of described multistage pump balancing drum, have continuous groove 6 on the outer side wall of described multistage pump balancing drum, in the gasket groove 4 of described multistage pump balancing drum rear end seal ring 7 is set.
