Abstract
The present invention relates to a low noise pipeline pump. An upper connecting piece and a lower connecting piece are respectively arranged at both ends of the inner sleeve and the outer sleeve of an outer shell for the motor of the pipeline pump and are welded together with the inner sleeve and the outer sleeve of the outer shell. The lower connecting piece is fixed on a motor cabinet, and a sealing ring is arranged in the connected point of the lower connecting piece and the motor cabinet. A motor cover is provided with an oil feeding hole with a sealing plug. An upper mechanical seal is arranged at the connecting part of the motor cabinet and a motor shaft, and a lower mechanical seal is arranged at the connecting part of a lower mechanical seal cabinet and the motor shaft. The motor cabinet is provided with an oil feeding hole with a sealing plug. The motor cabinet is provided with an oil discharging hole; one end of the oil discharging hole is communicated with a motor room; the oil discharging hole is provided with a sealing plug. Due to the adoption of the structure, the pump can achieve the purposes of favorable lubricating effect and low noise; besides, the pump can be suitable for being used at different pipeline temperatures to improve the service efficiency of the pump and prolong the service life of the pump.
Description
One. technical field
The present invention relates to a kind of water pump, particularly a kind of low noise pipeline pump.
Two. background technique
Pump has been widely used in our daily life and all trades and professions, along with pump is used widely, the division of labor of pump is more and more thinner, usage requirement to pump is also more and more higher, the pump that particularly in water supply line, uses, because long-time the use, bearing on it in motor can generate heat, make the lubricant oil in the bearing to consume because of heating, thereby can not play lubricated effect, particularly general pipeline is cold water pipes, and the design of its pump also all is for the various parameters that adapt in the cold water pipes design, along with the development of society, the application of hot water pipeline is more and more, because when the raising of pipe temperature in the hot water pipeline, conventional pumps were used in this hot water pipeline, the lubricant oil in the bearing is easier to be consumed, it is well lubricated to cause bearing not obtain, last motor can be killed, and motor is burnt, and causes shorten greatly the working life of pump.And this pump in use noise is big, sealing effect is bad, so conventional pumps can not satisfy present usage requirement far away.
Three. summary of the invention
The objective of the invention is to design a kind of high lubricating effect, noise low, can adapt to the pump that different coolant-temperature gages use, to improve the utilization efficiency of pump, prolong the working life of pump.
The present invention adopts following structure to realize above-mentioned purpose, be respectively equipped with the upper and lower link that welds with the inside and outside cover of shell at the inside and outside cover of the shell of pipeline mounted pump motor two ends, following link is fixed on the motor cabinet, following link and motor cabinet connecting part are provided with seal ring, have oil hole on the motor cover, sealing plug is arranged on the oil hole; Machine envelope on motor cabinet and motor shaft connecting part have, following machine envelope seat has following machine to seal with the motor shaft connecting part; Have oil hole on the motor cabinet, sealing plug is arranged on the oil hole; Oil drainage hole is arranged on the motor cabinet, and oil drainage hole one end communicates with the motor room, and sealing plug is arranged on the oil drainage hole; The cover two ends are weldingly fixed on respectively on the groove of upper and lower link in the shell, and upper and lower link is weldingly fixed on respectively on the inwall at shell overcoat two ends.
Adopt this kind structure, the sealing effect of entire pump has strengthened, pipeline mounted pump can well be operated in the pipeline, owing to can inject lubricant oil as required at any time in the motor, make the high lubricating effect of motor middle (center) bearing, and owing to have lubricant oil that the operating noise of motor is reduced greatly in the motor, particularly use on the pipeline of various different temperatures, as hot water pipeline, because the hot water temperature's height in the pipeline, the existing lubricant oil of pump inner bearing is subjected to temperatures involved, can not well play lubricated effect, at this time in oil hole, inject machine oil, can make motor not be subjected to the influence of pipe temperature by structure of the present invention, still can well work, and can also make motor be difficult for heating owing to inject machine oil, prolong service life of equipment, particularly make the noise of pump reduce greatly, adopt this structure to refuel, thereby pipeline mounted pump can be in the good working order all the time according to different usage requirements or different situations motor to pipeline mounted pump.Because cover and shell overcoat two ends and upper connector, following link become one by being welded to connect in the shell of motor, make mechanism compacter, precision is higher, has prolonged working life.
Four. description of drawings
Fig. 1 is an embodiment of the invention structural drawing
Five. embodiment
As shown in Figure 1, be the specific embodiment of the invention, pipeline mounted pump comprises: motor 22, the pump housing 10, impeller 23, motor cabinet 15, in the shell of motor 22 cover 18 and shell overcoat 19 two ends be respectively equipped with shell in overlap 18, shell overcoat 19 welding upper connector 4 together, following link 13, following link 13 is fixed on the motor cabinet 15, following link 13 is provided with seal ring 12 with motor cabinet 15 connecting parts, machine envelope 6 on motor cabinet 15 and motor shaft 5 connecting parts have, following machine envelope seat 24 has following machine envelope 7 with motor shaft 5 connecting parts, have oil hole 2 on the motor cover 3, sealing plug 1 is arranged on the oil hole 2; Have oil hole 8 on the motor cabinet 15, sealing plug 9 is arranged on the oil hole 8; Oil drainage hole 11 is arranged on the motor cabinet 15, and oil drainage hole 11 1 ends communicate with motor room 14, and sealing plug 21 is arranged on the other end of oil drainage hole 11; Cover 18 two ends are weldingly fixed on respectively on the groove 20 of upper and lower link in the shell, and upper connector 4, following link 13 are weldingly fixed on respectively on the inwall 4 at shell overcoat 19 two ends.
When pipeline mounted pump need add machine oil, open the sealing plug 1 on the motor cover 3, add machine oil by oil hole 2, machine oil can enter on the bearing 16 by the gap 17 of stator and rotor, thereby guaranteed motor bearings 16 be in forever lubricated in.Open the sealing plug 9 of the oil hole 8 on the motor cabinet 15, machine oil is joined in the sealing chamber 25, make going up machine envelope 6 and following machine envelope 7 can be in machine oil and be convenient to the machine envelope in soaking and better bring into play seal action, the present invention also can not open the oil hole (not shown) on motor cabinet 15, the machine envelope can play the effect that strengthens sealing effect equally on directly increasing in motor cabinet.Oil drainage hole 11 on the motor cabinet can be discharged to the machine oil in the motor room 14 outside the pipeline mounted pump by oil drainage hole 11, thereby makes the machine oil in the motor room 14 have convertibility.Upper connector 4, down link 13 with overlap 18 in the shell, shell overcoat 19 is by welding, well be connected as a single entity.
