Abstract
The utility model relates to a gear pump with a shock-absorbing air bag, comprising a pump body assembly, a pump cover assembly, an inlet passage, an outlet passage, a rotor assembly, a gear assembly, an outlet valve, an overflow valve, a sealing member and an installation member, wherein a filter and a float valve assembly are arranged in the outlet passage, and the gear pump with the shock-absorbing air bag is mainly characterized in that the shock-absorbing air bag is arranged in the outlet passage. When the pressure of the outlet passage rises, the air bag is compressed until the pressure is balanced; and pulsating pressure change generated during the operation of the pump is absorbed by the air bag so that pressure in the pump can be stabilized, thereby reducing shock and noise generated by pressure change. The gear pump with the shock-absorbing air bag has the functions of shock absorption and noise elimination, leads to stable pressure as well as low shock and noise during pump operation, and increases the operational reliability of the pump and supporting facilities, thereby being applicable to an oil-gas separation combination pump on an oiling machine.
Description
Technical field
The utility model relates to a kind of gear pump, particularly about a kind of oilling machine unipump.The utility model is applicable to the conveying equipment of oil product and other liquid.
Background technique
Gear pump generally comprises the pump housing, inlet passage, outlet passage, rotor assembly, gear assembly, outlet valve assembly and spill valve, is widely used in the conveying equipment on the oilling machine.Gear pump is in the outlet passage of zone of high pressure, and its space is less, and fully balance absorbs fluctuation pressure, produces bigger vibrations and noise when making gear pump work.Especially use this liquid gas two-phase fluid-mixing medium operating mode on oilling machine, fluid-mixing has big energy and discharges in the outlet port that pressure is arranged, make the fluctuation of outlet channel inner pressure bigger, not only produce very big vibrations and noise, and damage pump and auxiliary facility easily, influence product running stability and reliability.
Summary of the invention
The purpose of this utility model is to have shortcoming at prior art, and a kind of have damping, noise elimination function are provided, and operation pressure stabilization, vibrations are little, noise is low, the gear pump of the band shock-absorption air bag of good reliability.
The technological scheme that realizes the utility model purpose comprises pump assembly, pump cover assembly, inlet passage, outlet passage, rotor assembly, gear assembly, outlet valve, relief valve and Sealing and assembling set, being provided with filter and float-controlled valve assembly in outlet passage, mainly is to be provided with shock-absorption air bag in outlet passage.
The utility model beneficial effect compared with prior art is in the outlet passage of zone of high pressure shock-absorption air bag to be set, this shock-absorption air bag is according to the space size in pump inner high voltage district, shape designs, and be fixedly mounted on corresponding position, when pressure raises, make the air bag compression until pressure balance, when producing the fluctuation pressure variation in the pump work, fully absorbed by air bag, make the pressure stability in the pump, reduce vibrations and noise that variation in pressure produces, has damping, noise elimination function, make the pump operation pressure stability, shake little, noise is low, improves the operational reliability of pump and auxiliary facility.

Embodiment
Now further describe the technical solution of the utility model in conjunction with the accompanying drawings and embodiments.
Gear pump as Fig. 2, band shock-absorption air bag shown in Figure 3, comprise pump assembly 8, pump cover assembly 6, inlet passage, outlet passage, rotor assembly 5, gear assembly 7, outlet valve 3, relief valve 10 and Sealing and assembling set, in outlet passage, be provided with filter 4 and float-controlled valve assembly 1, and be provided with shock-absorption air bag 2.Shock-absorption air bag 2 adopts the blow moiding method manufacturing according to the space size in pump inner high voltage district, shape, and inside has the bellows structure of cavity, is fixedly mounted on the corresponding position of outlet passage, is used for stable high voltage district hydrodynamic pressure, reduces vibrations and noise.Be provided with filter screen 9 in the inlet passage.On the oilling machine pipeline, the outlet of outlet valve 3 is connected with the metering mechanism import.
