Abstract
The utility model relates to a liquid pump, comprising a cylinder, a piston and a drive mechanism. The both ends of the cylinder are provided with an outlet and an inlet, and the outlet and the inlet are connected with one-way valves. The piston is provided with an expansion ring whose inside is communicated with a cylinder chamber. The drive mechanism comprises an eccentric bearing installed outside the driving shaft, and the external shaft sleeve of the eccentric bearing and the piston rod are hinged. The cylinder and the drive mechanism are fixed on a pedestal. The utility model has the advantages of high output pressure, simple structure, stable running and long service life and is especially fit for being used as a boiler feed water pump.
Description
The utility model relates to a kind of liquid pump.
Application number is a disclosed reciprocating type cylinder and two chambers multifunctional ceiling press pump (March 9 1988 day for announcing) in 87106319 the patent application document, has overcome intermittent big, the deficiency such as power consumption is high, power is low, volume is big of reciprocating pump discharge opeing commonly used.But the driving mechanism of it and existing reciprocating pump all is the to-and-fro motion that drives piston by bent axle, and complex structure is easy to wear.And its delivery pressure is relatively low.
The purpose of this utility model is to provide a kind of pressure height, and is simple in structure, the two-chamber reciprocating pump of long service life.
The purpose of this utility model is achieved in that it comprises cylinder body, piston, driving mechanism, and all there are outlet and inlet in the two ends of cylinder body, and outlet and ingress all are connected with one-way valve.Have packing on the piston, the inside of packing communicates with the cylinder chamber, and described driving mechanism comprises the capacity eccentric bearing that is installed in outside the driving shaft, and the external axle sleeve and the piston rod of capacity eccentric bearing are hinged, and cylinder body and driving mechanism all are fixed on the base.
Be provided with packing on the piston of the present utility model, when compressed liquid, be compressed the inside that liquid acts on packing, the outside of packing is closely contacted with cylinder body.Can be with liquid compression to higher pressure.Adopt capacity eccentric bearing to drive reciprocating motion of the pistons, simple in structure, operate steadily, not easy to wear, long service life.The utility model can be used for compressing multiple liquid.Be particularly suitable for as boiler feed pump.In the industry or life process of adopting steam to heat, the condensed water of discharging in the heat exchanger can directly send back in the boiler recyclingly with pump of the present utility model, help energy saving and conserve water resource.
Fig. 1 is a structural representation of the present utility model,
Fig. 2 is the plan view of Fig. 1:
Fig. 3 is the structural representation of driving mechanism,
Fig. 4 is the structural representation of carriage.
For example the utility model is done more detailed description below in conjunction with accompanying drawing: cylinder body and driving mechanism all are fixed on the base 1.All there are outlet and inlet in the two ends of cylinder body 2, and each outlet and ingress all are connected with one-way valve.Have two packings 4 on the piston 3.All there is the hole that communicates with the bottom and the cylinder chamber of packing 4 both sides of piston 3.The two ends of cylinder body have front cover 5, rear end cover 6 respectively.Piston rod 7 passes two end caps, and is provided with sealed packing 8, sealed packing 9.The driving shaft 10 overcoat capacity eccentric bearings 11 of driving mechanism have connecting rod 12 on the external axle sleeve of capacity eccentric bearing 11, hinged by link rod 12 and piston rod 7, the hinged place is provided with bearing 13.Be fixed with carriage 14 on the base 1, have axle sleeve 15 on the carriage 14, piston rod 7 passes axle sleeve 15, makes the motion orientation of piston rod 7.
