Boiler multi-stage pump ring (also known as sealing ring), the general number of water pump and the number of rings is the same, that is, a 5-level pump, then there are five rings, a mouth ring, 4 mouth rings.  Boiler multi-stage pump port ring role:         1, the boiler multi-stage pump ring is the role of the impeller and the pump shell to form a narrow, twists and turns of the channel, to increase the flow resistance of the medium to achieve the purpose of reducing media leakage. Boiler multi-stage pump port ring also set up to protect the main parts of the pump from the role of wear and tear, the ring ring wear, you can repair or replace the new ring, to restore the normal assembly gap, so economical and easy maintenance.         2, the gap between the mouth of the General Assembly will be the efficiency of the use of low pump, pump pressurized fluid will be too much from the pump outlet area along the impeller and the mouth of the ...

Throttle device is used to measure the flow, its working principle is as follows: in the pipeline with a cross-section changes in the orifice or nozzle and other throttle, when the fluid flow through the throttle due to shrinkage, Resulting in static pressure difference, the use of pressure and the relationship between the flow rate can be further measured flow. For non-calibrated throttle devices, as long as it is geometrically similar and kinetic to the throttle device that has been fully experimentally calibrated, the static pressure difference between the front and rear of the throttle can be considered under the known parameters There is a definite numerical relationship between the flow of the fluid flowing through the fluid. So you can measure the flow through the pressure difference.    The correctness and reliability of the flowmeter installation is important for ensuring that the differential pressure signal output from the throttle device is accurately transmitted ...

Feed pump inlet filter, also known as condensate pump inlet filter, used in the thermal power steam boiler condensing tower condensate pump inlet, used to eliminate impurities in the media to protect the normal use of equipment and valves. Feed water pump import filter use:         Mainly applicable to a variety of different filtration, dust and separation requirements for petroleum, chemical, mineral, food, pharmaceutical, painting and other industries filter. Painting filter material can be divided into two kinds of metal and plastic, filter installed in the gun on the location of different types, generally stainless steel and nylon material is better.       Feed pump inlet filter by process points:         1, multi-layer spot welding filter.         2, multi-layer package edge filter.       Stainless steel feed pump inlet filter mesh by shape points:         Rectangul...

Stainless steel sewage pump is designed according to national standards, suitable for long-term delivery of any concentration of strong acid, alkali, salt, strong oxidants and other corrosive media, the shell, the main pipe, outlet and over-flow parts all plastic alloy molding Sintering made of the pump part of the host all placed in the liquid, with strong corrosion resistance, good wear resistance, high mechanical strength, no oxidation, non-toxic decomposition characteristics. Stainless steel liquid sewage pump and medium contact with the parts, the Department of polyvinyl butyral modified phenolic glass fiber, high temperature molding of phenolic glass steel parts, connecting pipe, the liquid pipe semi-dry rolling system Into the phenolic glass pipe, the impeller sleeve assembly are used phenolic cement and liquid pump pump shaft stick into one, the liquid under the assembly are used phenolic cement mortar, into the liquid without metal and medium contact, corrosion resistance Abs...

YW submerged non-clogging sewage pump is based on the combination of advanced technology at home and abroad, the use of liquid pump characteristics and the successful development of a new generation of liquid sewage pump products, with significant energy saving effect, anti-winding, no clogging and other characteristics, in the row To send solid particles and long fiber garbage has a unique effect. It is a vertical liquid structure, working in the pump immersed in water, the liquid depth of up to 0.5 ~ 5m, and the use of a unique single leaf or double blade impeller structure, can effectively through the pump diameter 5 times the fiber material and diameter For the diameter of 50% of the solid particles. YW submerged non-clogging sewage pump hydraulic performance advanced, mature, the product tested by the performance indicators have reached the relevant standards, products on the market with its unique efficacy, reliable performance, stable quality by the majority of users welcome an...

Multi-level high-pressure feed pump idling is a very dangerous behavior, will cause unnecessary impact, then why will the centrifugal pump empty, there will be what harm, how to deal with idling, first of all is sure that the seal will be damaged, Sealed flushing water normally open, this problem should be able to solve it?   Multi-stage high-pressure feed pump idling reasons:         1, the pump is not sufficient import media or water pressure is not enough, or pump inlet pipe blockage, or pump air inside the cavity is not exhausted;         2, the pump idling, the impeller without contact or very little contact with the media, can not work effectively, the liquid can not be properly transported out, these are doing useless work;         3, because there is no effective work, the motor load is very small, resulting in a small current, the impact of the motor will not have anything, the pump idling on the pump is real...

Now the performance of the pump material are good, basically no warm pump system, and improve the reliability of the device, reducing the complexity of the system, and now the domestic pump material performance are good + dynamic clearance gap, so basically no warm pump System , but because of the import of the pump to move the gap between the small high efficiency, spare pump must be warm pump, but also consider the upper and lower temperature of the pump casing in the control requirements. Upside down can be recovered quality, so there is a pump running standby pump are used to warm up. Now a lot of pumps do not have a warm pump, not because it is not imported pump, and material and structure are related to it!         Is warm and warm should not be much difference, all from the role of warm pump, the general situation, the initial start of the pump, to use the warm, as a backup pump, when there are other pumps running, to start the pump, Use upside down.  ...

Boiler feed pump consists of multiple parts, of which the boiler feed pump hydraulic coupler is an important part of its operation in the boiler feed pump plays an important role. Hydraulic coupler mainly by the pump wheel, turbine and rotating jacket and the composition of these parts, each part has its own role.  Boiler feed pump with hydraulic coupler reasons:     1, simplify the water supply console, improve the boiler water supply system to run the reliability.     2, the unit to participate in FM, peaking, often under low load operation, the use of hydraulic coupling speed, compared with the throttle adjustment, the pump power consumption can be significantly reduced.     3, the use of speed to the pump, the simplified water supply console and operation switching steps for the boiler to achieve full adjustment of the water supply to create a good condition.     4, to facilitate the hos...
