HSMJ, HSNJ series of three screw pumps for the waterindustry-specific pump, used in the hydro-electric power unitturbine governor oil supply system on the source device, the pumpis in my series of three screw pumps Secretary HSN developed on thebasis of the in the high-voltage products. Designed andmanufactured in accordance with GB/T10886-2002。
、ProductIntroduce
The three screw spiral shaped surface by a specialcomposition, screw rotation, its movement of liquid from the sealedchamber along the axis of imports has been inhaled and continuouspulse-free delivery to the exit. Therefore, the pump sports asmooth, low noise, traffic and stability；
Initiative screw driven screw with axial low-pressure balance,fluid pressure-driven rotation, so that screw is in tension andthus screw easily deformed. Initiative, driven screw non-contact,so screw no wear, long life, and has a strong self-priming ability；
Pump core assembly can be removed as a whole. As long as themotor hanging open, can be achieved, easy field maintenance.Electrical double lug for easy lifting。

NO.4A few tips on pump selection
1、Please select the appropriate rotational speed in accordancewith the viscosity of the liquid, so as to ensure that NPSHr of thepump can meet the practical suction conditions of our customers.
2、If the medium viscosity exceeds the range on the performancetable, please contact our technology department. We will alwaysprovide you with satisfactory service.
3、After the pump selection, please ask for the measurements of thepump and the electrical machinery unit’s accessories for the basicconstruction design.
4、Whether we will deploy the safety valve depends on customer’srequest and the safety valve only protect the pump for a instant,can not be the overflow valve of conduit.
Please provide the following data when you order pumps
The structure type of the pump
The working flux of the pump-Q
The inlet pressure (or the vacuum degree)of the pump-P1
The outlet pressure of the pump-P2
The working temperature of the medium-T
