Horizontal Split Case Pump, Double Suction Pump, Split Casing Pump

We are professional manufacturer for Horizontal Split Case Pump, Double Suction Pump with high and stable quality, and we have made many water pump solutions for many customers.

General Description:
Tpye SH, XS Split Case Pump/Double suction pump is new type of single stage double suction split case centrifugal pump with high pefformance. They are widely used in delivering liquids to the water plant, circulation water system of airconditioner, pipe net syetem of supplying heated water, construction, drainage
Pumping station, power station, industrial water supply system, ship industry, mine and etc. Type SH,
XS split case pump is advanced products developed from type SH. S. SA. SLA. SAP pumps.

Split Case pump, The technical parameter of pumps:

Speed: 990, 1480 and 2960 r/min
Voltage: 380, 6K/10KV
Inlet and Outlet: 150~600mm
Flow range: 68~3975m3/h
Head range: 6~180m
Fuel: Diesel
Engine: DEUTZ engine, water cooled

Temperature range: Maximum temperature ≤ 100 ° C of the liquid, a special configuration of up to 150 ° C, ambient temperature ≤ 40 ° C
Maximum working pressure (inlet pressure pump pressure +): 1.0MPa (Hsp ≤ 75m) or 1.6MPa (Hsp>75m)
Special configurations can be respectively 1.6MPa or 2.5Mpa
Allows transportation media: Clearwater physicochemical properties similar to the branch water or other liquids
Sealed pipe parts: Inlet pressure ≥ 0.03 Mpa without installation

TECHNICAL ADVANTAGE
1. Type XS pumps work stably with less noise and vibration and can work at a lifting speed due to. Short Support at both sides, thus they can be widely used.
2. The pipelines arrangement of type XS pump looks simple and beautiful due to inlet and outlet at a Same center line.
3. The same rotor of type XS pumps can be operated at reverse direction to avoid damage to the pumps By water hammer.
4. Unique design of type XS pumps working at high temperature using middle support to fasten the Pump casing and using cooling seals oil lubrication bearing then pump suitable for working at 200 degree Especially for suppling heated water to pipe net system.
5. Type XS pump casting parts can be vertically or horizontally mounted acoording to different working Condition, with mechanical seals or packing seals.
6. Type XS pumps look beautiful with visible lines adopting industrially designing.

COST ADVANTAGE:
1. The efficiency of XS pumps are 2%~3% higher than the same type pumps due to adopting advanced Hydraulic model and thus minimum the operating costs.
2. The NPSH of type XS pumps are 1-3 meters lower than the same type split pumps due to using Advanced hydraulic model and advanced manufacturing technique and thus minimize the foundation costs And extendling the using life.
3. Type XS pumps are suitable for any site working condition due to using SKF NSK bearing and other Parts chosen by the customers and thus minimize the maintenance costs.
MAINTENANCE ADVANTAGE:
1. It is very easy and simple to replace the mechanical seal due to usine container type machaniacl seal.
2. It is rapid easy to assembly and dismout the rotor parts due to using elastic ripess assembling.
3. It is unnecessary to make adjustment when assembling

Application:
XS series Split Case Pump is widely used for water plant, irrigation, drainage pumping station, power station, water circulation of air-conditioning, industrial water supply system, fire system and shipping industry as well as for the general purpose in the oil refining industry.


 

The domestic current situation of the die-casting mould

Die Casting Mould industry has developed rapidly in our country, the total output growth significantly, domestic die casting mold production after the United States, has become the second in the world, become the veritable die-casting superpower. It can have such achievement because of our country with unique broad market advantages and relatively cheap labor force. Depend on very obvious price in the international trade market, we produced the die casting mould which occupies a bigger superiority, according to the situation, in the future Chinese die casting industry development prospects are very broad.

The designing of die casting tooling
1, According to the materials, shape and precision product, analyze technology, decide of the process.
2, Confirm the location of product in the mold cavity. Analyze parting surface, overflow system and the gating system.
3, Design the various activities of the core are assembled and fixed method.
4, Design the core-pulling distance and force.
5, Design the ejection device.
6, Confirm the die casting machine, design the mould base and the cooling system.
7, Checking the mould size and die casting machine, drawing the process flowchart and component of die casting mold.
8, Design is complete.

Aluminum injection mould material and materials and its properties

Material of aluminum die casting mould: H13, ASSAB DIEVAR, SKD6;

Mould base: #45 steel, standard mould base (LKM);

Hardness after treatment: RHC 48~52;

Standard Configuration: Cooling system;

Tolerance: 0.1mm;

Machining equipment: CNC gantry milling machine, middle-speed WEDM machine, slow-feeding EDM, die spotting machine;

Lead time of die casting mould: 40 days-60 days.

What is the Moldflow analysis, this conception derived fromtaiwan. it's a precess through the computer for injection molding simulation by data simulate software, and get data result. Then assess the feasibilty of the mold program through these results to perfect mold and production designation.The common software for plastic mold such as moldflow, moldex 3D and so on. And the common software for Aluminum Die Casting Parts such as PROCAST, FLOW 3D and so on.
