Introduction of screw pump rotor

1The cEPTTr component of the screw pump is composed of rotor and stator. JCEP rotors are usually made of metallic supplies and are manufactured into EPT EPT angles via EPTT cutting EPTTs. A EPTT framework consisting of a steel rotor and an elastic stator helps make it capable of conveying components conXiHu (West EPT) Dis.Hu (West EPT) Dis. reliable particles.

two The rotor is put in the stator, sealed with each other in a helical construction. When the rotor rotates, the interior continuity of the stator is working, the liquid in the closed place operates continuously, conveying out from the suction aspect of the quotNo pulsation quot and quotquantitative quot EPTT.The outer thread and the thread of the rotor are produced according to the EPTT processing

EPT of rotor

EPTT metal, stainless metal, SS304, SS316L,904L and so forth.

The content of rotor my business frequently utilised: 40Cr, Cr12mov,SS304, SS316L, 2205 and 904L

JCEP pump with different rotor /stator geometries, running strategy and conveying principle

The/geometric form beEPTTs to a single head screw/rotor. With a round cross-EPT, a big pitch and a big thread depth, the depth is continually changing as the rotor rotates in the stator. The cross-EPT of the stator is the same as that of the rotor, even so, the stator is a two-headed internal thread one hundred eighty deg apart, and when the stator and the rotor are meshed collectively, they form one/two stator cavities. When the rotor rotates, the continuous EPTT cavity among the rotor and the stator moves the medium in which the packet is sent easily and continuously from the suction stop of the stator to the discharge finish.

The flow price is deterEPTd by the pitch, diameter and eccentricity of the rotor/stator, and the pace of the pump.

The outlet pressure depends on the collection and the pressure difference of maXiHu (West EPT) Dis.mum 6bar 85psi for every level,

The 2-stage screw pump with s-form geometry can obtain a strain difference of 12bar 170psi and hundred percent of movement.

The shape of a single-stage screw pump with L-formed geometry is the same as that of the S-shaped 2-phase pump, with the identical diameter and eccentricity. The rotor/stator screw pitch of L-formed geometry is twice moments than with the S-condition geometry. Consequently, in comparison with the S-form geometry with the maXiHu (West EPT) Dis.mum pressure variation of 6bar 85psi, this pump can be twice times flow of it.

EPTT head thread geometry stator

The rotor of the double head thread has the Ellipse cross EPT large pitch and the massive thread depth, the rotor is the eccentric circular rotation motion in the fastened stator, the stator also has the same geometrical condition as the rotor, but the stator has a a few-head thread which is 120 deg aside.

When the stator and the rotor areocclusal, the 2/3 geometric cavities are shaped amongst them, and when the rotor rotates, the constant EPTT cavity amongst the rotor and the stator is transported efficiently and repeatedly from the suction stop of the stator to the discharge end.

The circulation fee is deterEPTd by the screw pitch, diameter and eccentricity of the rotor/stator, and the pace of the pump. The outlet pressure is dependent on the sequence and the maXiHu (West EPT) Dis.mum force difference 6bar 85psi for every level.

The cavity measurement of the two-headed thread geometry is about 75% of the S/L type, but its cavity is opened two times for every change, and the 1/2-level geometry of the cavity is only opened after per turn,

So it is raises 50% circulation charge each flip for the double head thread geometry of the rotor/stator than the S/L kind,

Two-head thread geometry of the two-phase screw pump, with 150% movement fee far more than S geometry solitary stage pump, accomplish maXiHu (West EPT) Dis.mum pressure variation 12bar 170psi.

EPTT head thread geometry shape dimension of one-phase is same as screw pump and two-stage screw pump, the ellipse and eccentricity are the same too. But the screw pitch is 2 times occasions the rotor/stator of the two-head 2-phase condition. So with the maXiHu (West EPT) Dis.mum strain big difference of 6bar 85psi, this pump makes 300% of the circulation ratio than S-form geometry
