最美的情话屏蔽泵特点(英文)
The Canned Pump is a centrifugal pump, clo coupled to a Canned Motor in such a way that there is no dynamic shaft al, no couplings and no ball bearings. The motor is cooled by the pumped liquid and the sleeve type Bearings are lubricated by the same liquid. This eliminates the need for external lubrication.
The stator of the driving motor, which is usually three pha squirrel cage induction motor, which is hermetically contained in a stator containment that consist of an external frame tube, out board & inboard end plates and the internal cylinder liner. The rotor which is welded on the shaft, is also encapsulated with a non magnetic liner. Both stator liner (Stator Can) and rotor liner (rotor can) are al welded at both ends, and does not allow any part of the motor to be expod to external environment or internal pumped liquid.
Leak Free Pumping For Safer Future
龙头渚>项目风险With wide experience in solving pumping problems, we can provide you with a range of alless pumps, alless canned motor pumps, centrifugal pumps with exceptional operatin
g reliability.

Dynamic canned motor pumps are highly efficient due to reduced life cycle operating cost, zero fugitive emissions, eliminating environmental pollution risks, and allowing very safe pumping of fluids without wastage of valuable, hazardous, even explosive fluids, due to alless construction and other unique features.

    The wide range of models available, allows top quality standardization. High efficiency is combined with superb handling and ea of installation is attributed to the experience of the dynamic team and clo collaboration with large number of customers.
    The uniqueness of its drive motor construction is that, there is no dynamic shaft al, no coupling and no ball bearings. The motor is cooled by the pumped liquid and the sleeve type bearings are lubricated by the same liquid. This eliminates the need for external lubrication. The stator of the driving motor, which is usually three pha squirrel cage induction motor, is hermetically contained in a stator containment that consists of ex
ternal frame tube, outboard and inboard end plates and internal cylinder liner. The rotor which is welded on the shaft, is also encapsulated with a non - magnetic liner. Both stator can and rotor can are al welded at both ends, and does not allow any part of the motor to be expod to external environment or internal pumped liquid. The can reprents a static atmospheric al and parates the rotor compartment from the stator compartment, such that levels of aling of < 10 -7cc /c are achieved. To ensure integrity of the canning. The versatile drive system has exceptionally improved the operating limits for pressure, temperature and toxicity of the flow of the product responding to heightened safety and environment protection requirements all over the world. Dynamic canned motor pumps are flame poof and are cmri certified to EEx-d 11b T4(Ex) ds, IS: 2148-2004 AND weather proof protection : IS:12063-1987, IP-67.
Installation and Space Requirements
Dynamic canned motor pumps are characterized by extreme compactness and conquentially low space requirements, becau the pump and motor form integral unit,
neither ba plate nor special foundations are required, our units are not at all nsitive to distortion caud by the piping, this is of special importance if heat transfer oils are to be pumped at high temperatures., this allows the pump to be installed in otherwi inaccessible places for e,g in ships and nuclear power stations. being noiless and vibration free.
Due to more stringent health and safety regulations canned motors are beneficial replacement, if properly installed and operated, canned motor pumps render technical process maintenance free and safe and contribute to incread productivity and reduced maintenance costs.描写景色的成语

Design & Construction Of Dynamic Canned Motor Pump
The Canned Motor Pump Design is very simple & has all standard features of conventional centrifugal pumps.
空间组织The Pump is categorized in three ctions- The Pump, the canned motor and the bearings.
The Pump is designed as per Hydraulic Institute standard. having back pull out design, keyed impellor, automatic axial thrust balancing, lf venting .flanges confirming to ANSI class 150,300 std. ASA CLASS 150,,ISO-2084 PN16,IS-6392 PN16 ,API. The impellor is either enclod or mi open type with maximum mechanical strength for high efficiency and low NPSH, back vanes are provided for reducing axial thrust, the impellor is positively locked on the shaft and cannot get loo under rever rotation.

The temperature class of motors is class H & Class C, Insulation of the windings are provided according to the class specified and internationally sourced for compatibility with IEC Motor specification.

The Bearings are journal type and are lected for having excellent lf-lubricity property, the bush bearings made of carbon graphite, silicon carbide or tungsten carbide are provided, the load capacity is also one important criteria for bearing lection. Different grades of carbon grahites are choon for chemical resistance, low friction coefficient, high heat stability, wear resistance and good compatibility with metal sleeves.
Safety
电饭煲目前最好的内胆Canned Pumps are normally designed and manufactured to have condary Containment.

Stator liner with a back up ring works as the primary containment and the outer motor frame work as the condary containment, the condary containment will prevent the liquid from leaking out into atmosphere for long enough to detect the failure of the primary containment.

There are safety options available for safety equipments are available such as bearing wear indicator, dry run protection unit, thermostat embedded in the windings, RTD on recirculation line and so on.

Dynamic Canned motors are provided with option of bearing wear indicator electronic type or Mechanical Type. The LED Displays the bearing health in three zones. Green is f
or Good, Amber is for Not Good and Red indicator is for bad bearings, which need immediate replacement. Alarm signal is also provided along with motor tripping device inca the bearings are not replaced inspite of crossing danger zone. Since, the indication is continuous and real time, it gives the operator an idea when the maintenance work is needed. A light Indicator is also provided on the electronic device to indicate the direction of rotation of the motor, as nothing can be en from outside the pump visually for motor inspection.

A micro thermostat embedded in the hot spots of the electrical windings will trip of f the motor on electrical overload.

Dry Run Protection device , being a current monitoring device , trips of the pump in the event of drop in the flow of liquid to unsafe limits, other conditions , such as rotor locking, cavitation , air locking ,single phasing etc. can be detected.
