HSNH440-46三螺杆泵【黄山】

A, HSN three screw pump is introduced

HSN series three screw pump for delivery of fuel oil, lubricating oil,hydraulic oil and other oils and lubricating liquid. The transmissionmedium not containing any material abrasive particles and the corrosion of pump material.

HSN series three screw pump is used as the fuel pump, turbocharger andfuel furnace in the fuel system; used for transmission and pumps in the oil system; in all industrial fields are used as lubricating oil pump;hydraulic pump for various hydraulic transmission device in the.

HSN series three screw pump applicable pressure range: 4.0Mpa,temperature ≤ 150 ℃, viscosity of 3-760cst

Two, structural characteristics

Rotation of the spiral surface of HSN series three screw pump is composed of special type line consisting of active screw, the dynamic seal chamber will bring the liquid from the suction port of the suctionalong the axial direction and no pulsation continuous, transported to theoutlet. The main rod adopts the hydraulic pressure balance, from the axial force rod support on the rear lid, and by the hydraulic pressure drive rotation, so screw type only transfer of hydraulic torque, no stress,no wear, for all the transmission parts, all by the transported mediumlubrication. The main rod radial by balancing piston position, and by the clearance between the piston and sleeve balance that high pressure chamber and separate the sealing cavity, with the mechanical seal cavity,cavity of the oil return hole and pump suction cavity, so it is not affected by the discharge pressure. Because the components of combinationseries has a variety of structure, can be used for horizontal (H), flange type (F) and vertical (S) installation.

According to the transmission medium to provide heating or cooling structure.

Three, the scope of application

Used in the heating device of fuel injection, fuel supply and delivery pump.

In machinery industry used for hydraulic, lubrication and remote control motor pump.

Be used for loading in chemical petroleum and chemical and food industry, transportation and for pump.

Ship used in conveying, pressure, pump fuel injection and lubricating oil pump and the hydraulic.

Four, HSN series three screw pump products structure advantages

1, HSN series three screw pump product brief introduction:

A driving screw and a driven screw of HSNH series three screw pumpadopts the hydraulic pressure balance device, liquid is transferred in the pump cavity continuous, uniform axial linear movement, no pulse, low noise, smooth operation, flow pressure is stable, stable work, small vibration.

General parts of HSNH series three screw pump has good compatibility,can be arbitrarily disassembled, replace the corresponding parts. Pumpless parts, simple structure, light weight, installation, repair, convenientuse, high efficiency, long life.

The axial force of the three screw pump driven screw support at the backor the driving screw, and by the hydraulic pressure drive rotation, driven screw drive, by the fluid pressure, there is no mechanical contact,between the driving and driven screws between the screw, there is oil filmprotection between the screw and a pump sleeve, the screw type surfaceonly transfer of hydraulic torque, not force, no wear and mechanicalfriction, on all the transmission parts, by the oil film to protect the transported medium formation and lubrication.

Three screw pump rod radial rotation beating by balancing piston sleeve can also be called sliding bearing positioning, and by the clearance between the piston and sleeve balance that high pressure chamber andseparate the sealing cavity, a sealing cavity in mechanical seal, no leakage, cavity of the oil return hole and pump suction into the cavity,thus not affected by discharge pressure.

Has a strong self absorption capacity, low energy consumption, without bottom valve and before each start filling.

Combined series has a variety of structure, can be used for horizontal(H), flange type (F) and vertical (S) oil immersed type (J) and suspension(K) installation.

According to the transmission medium to provide heating or cooling structure.

For the relatively poor lubrication medium, can be used with external bearing structure (W1) and metal bellows seal. To ensure the service life of three screw pump with good.

In order to protect the pump, motor and pipeline systems, the pump must be with external or internal safety valve device.
