Description
Technical field
This utility model belongs to external toothing positive displacement gear pump manufacture field, more particularly to a kind of horizontal gear oil peculiar to vessel
Pump.
Background technology
Gear pump is by the swept volume change formed between pumping cylinder and meshing gear and moves to convey liquid or make
Supercharging drum pump.It has good simple structure, small volume, lightweight, self-priming performance, anti-pollution, using the reliable, life-span compared with
The features such as long, easy to manufacture, easy to maintenance, low price.
External gear rotary pump is a kind of most widely used gear pump, more using between three-chip type structure, floating buss axial direction
The automatic indemnifying measure of gap, and adopt and rise as high as the banks to reduce the radial imbalance force of gear, as the number of teeth of this gear pump is less, lead
Cause its flow pulsation larger.
Utility model content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, and the technology for solving presently, there are lacks
Fall into, disclose a kind of horizontal gear oil pump peculiar to vessel.
This utility model provides a kind of horizontal gear oil pump peculiar to vessel, including pump case, gear, tooth axle, relief valve, end cap,
Sealing member and sealing gland.The end cap includes drive end bearing bracket and rear end cap；The gear includes driving gear and driven gear, institute
Symmetrical herringbone structure centered on gear is stated, the tooth axle includes active gear shaft and driven tooth axle；The driving gear passes through key
It is fixed on active gear shaft, the driven gear is scheduled on driven tooth axle by keying；The tooth axle is horizontally arranged in pump case,
The driven tooth axle is arranged on the lower section of active gear shaft, and the main driven tooth axle rear and front end is mounted on sliding bearing, described
Active gear shaft front end is connected with shaft coupling；The relief valve is arranged on above pump case；The front and back end of the pump case is separately installed with
Drive end bearing bracket and rear end cap, the oil-sealing measures of the pump case drive end bearing bracket are packing seal, and the sealing gland is installed in drive end bearing bracket
Front, is provided with sealing member between the front and rear cover and pump case；The left end of the pump case be intake flange disk, the pump case
Right-hand member be outlet flange disk, the intet diameter be more than outlet diameter.
This utility model is operated steadily using unique centrosymmetry herringbone external gear pump structure, compact conformation, is solved
Pocketed oil problem in gear pump of having determined operating, significantly reduces the uneven radial force produced during gear operation, greatly reduces
Pressure pulse and noise, reduce gear wear, and service life improves more than 50%, and is easily installed maintenance.
