XHB rotary piston pump features

XHB series rotary piston pump is a positive-displacement self-priming positive displacement pump. A pair of spiral rotors with the same clearance-free fit is installed in the pump casing. The prime mover transmits the power to the driving shaft of the pump through the transmission and the transmission mechanism, and the driving shaft gear drives the driven shaft gear to perform synchronous relative movement to form a suction chamber, a closed chamber and a discharge chamber. With the relative rotation of a pair of rotors, the pump forms a vacuum in the suction chamber, and the fluid is continuously sucked in, flows through the closed chamber and is discharged from the discharge chamber, forming a flow. The flow rate of the pump is linearly proportional to the speed. Since the pump does not change the size of its closed cell during operation, the pressure differential (or head) developed by the pump depends on the resistance of the discharge system. Because the structure of the pump is completely symmetrical, the pump's conveying direction is reversible.

1. XHB rotary piston pump is suitable for a variety of applications Rotary piston pump is a volumetric pump. Particularly suitable for conveying a variety of viscous, containing solid particles, fibers, wear-resistant, strict sealing, gas-liquid mixture, self-absorption, need to send positive and negative occasions.

2. XHB Rotary Piston Pump Energy-Saving The transmission and transmission of the XHB rotary piston pump are separated. There is a pair of synchronous gears in the transmission chamber. They work well in a highly efficient lubricant. Both shafts are driven simultaneously by the pair of gears. As a result, the rotor in the transfer chamber drains only the conveyed material and is therefore very efficient. Through practice, the XHB rotary piston pump consumes only 55%-75% of the normal pump power.

3. Long sealing life of XHB rotary piston pump The seal of XHB rotary piston pump adopts the state-patented mechanical seal. The spring that compensates for wear does not come into contact with the medium. There is only one relatively moving contact surface, and the seal material is made of a wear-resistant material such as silicon carbide. When there is some wear, the elasticity of the spring can be automatically compensated for wear by releasing, sealed in a sealed chamber with lubricating oil, and the rotational speed is controlled at a low speed of 350-600 rpm, so the service life is long.

4, XHB rotary piston pump is the most conducive to on-site maintenance of the XHB rotary piston pump designed a quick installation cover, as long as the open cover, you can quickly exchange or maintenance of all wearing parts, and the general pump pump to be unloaded from the system It can only be maintained; then it can be reinstalled, which takes a lot of time. Therefore, XHB rotary piston pump can greatly improve the machine's operating rate.

5, XHB rotary piston pump is very wearable In many occasions, due to the transmission medium with solid particles, in the transmission process caused rapid wear of the pump, the pump's life is reduced. The company has jointly developed a laser processing technology with a famous industrial university in China. It can apply laser hardening to the pump casing, which can greatly improve the wear resistance of the pump casing. In addition, a hardened steel liner is embedded between the pump body and the rotor, which includes both radial and axial, ie the entire pump body is protected. When the pump wears, the liner is replaced with a new one and the pump body is restored to its pre-wear condition. Therefore, the wear resistance and service life of the entire pump are increased several times.

6, XHB rotary piston pump work in low-speed XHB rotary piston pump between 350-600 rev / min, the movement speed is low, it brings several advantages, namely, small wear, long life, little damage to the transmission object, Low fever, stable work;

7. XHB rotary piston pump is insensitive to idling. The general pump is not allowed to idle because of its large friction and serious heat generation. Otherwise it will burn out quickly. The XHB rotary piston pump can at least ensure idling for 30 minutes.

8. The XHB rotary piston pump is insensitive to solid media. The transmission cavity rotor of the XHB rotary piston pump does not have to be matched like a gear pump, nor does it have a long contact line like a screw pump. Its transmission path is very short and the pump rotor Large space, insensitive to solid and fibrous objects;

9, XHB rotary piston pump small to do the same work, of course, the user hopes that the space occupied by the pump size is smaller, because the XHB rotary piston pump rotor space, compared to gear pumps, screw pumps and other volume pumps, its small size a lot of.

10, XHB rotary piston pump can be mixed in many occasions of gas and liquid, sometimes accompanied by natural gas, or there is air to enter, XHB rotary piston pump due to good sealing, can be mixed two-phase, gas-liquid ratio limitless.

11, XHB rotary piston pump self-priming performance pump has 8 meters of self-priming ability.
