The slag pump, which is not designed to be longer, cannot be ordered at a depth of one pool. Programs are affected by the insertion of depths, fluid-level fluctuations, axial support, bottom sedimentation, overhauling space and medium particles. The slurry pumping industry of ishikosei will first clarify the structure and operation of the reservoir in the context of underwater pumping communication, such as sp, sp, zjl, etc。
Distinguishing "line length" and "effective suction position"
Many of the sites said they needed to be longer, and what really needed to be confirmed was the location of the pump, the lowest liquid level, the highest liquid level, the depth of the bottom sediment and the direction of the feed. The longer the pump is not stable, the longer it is, the stiffness of the axis, the support mode and the vibration risk change. If there is sand or large particles at the bottom of the pool, the pump entrance may be blocked too close to the bottom。
Axis stability is the focus of custom
The common risk of slag pumps with long fluid is in the axis. After a change in the length of the axis, the coaxies, bearings, catheters, support points and operational speeds are reviewed. Only a simple length increase in the standard pump may be installed in the short term, with a long-term operation that is susceptible to vibration, heat or sealing anomalies. When not customised, the quartz slag pump industry evaluates the axial structure with the depth of the liquid pool, rather than simply changing the outer length。
The material is going with the medium, not with the habit
The media for sediments, concentrates, accident pools, acid alkali ponds and coal mud ponds vary widely. High-intensity slurry is concerned with wear and tear of leaves wheels and pumps, corrosive slurry depends on a liner or corrosive material, and large particle scenes depend on passivity. The quartz-pump slag-pump industry compares a liquid pump with a slag-pump, a gravel-pump, and a corrosive-resistant programme in order to make the tailor-made programme truly site-specific。
It's not passive until we think ahead of schedule
Once installed with a long pump, the height of the rig, the detachment route, the vent space, the platform load and the spare pump switching are considered. Many of the non-labelled equipment is not inoperable, but can not be removed or replaced when it is broken. During the procurement phase, the manner in which the leaves wheel, pump casings, bearings, coaxors, panels and fluids are to be maintained should be clarified. The slag-pump industry, which delivers liquid pumps, will place the original plant spare parts and overhauling borders in communication。
Custom pumps are also required to confirm the power and drive layout. The electrics are installed above the liquid surface and appear to be safe, but the platform height, tight belts, and coaxis affect the maintenance of the middle and shield. The direction of the fluid pipe is also to be attached to the site and to avoid temporary re-routing after the equipment has arrived。
Three common questions before customization
Q: can the underwater pump be indefinitely longer? Answer: no. This increase in length would raise issues of axial rigidity and vibration and would require structural review。
Q: what about the changes in the water level? Response: to confirm the minimum operating fluid level, adjust the pump position, control mode or choose other pumping options, as necessary。
Q: what about the deep bottom sediment? Response: depending on sediment thickness and particles, simply lowering the pump may not be effective and may increase congestion。
Non-standardization also involves drawing confirmation. The opening of the pond, the direction of the fluid, the position of the frank, the form of the panel, the installation of the electric power at the height and the overhauling of the station shall be confirmed at the drawing stage. The stone family slag-pump industry, in its long-slush sub-pump programme, will pre-communicate these interface conditions, as the cost of later changes tends to be higher than the minor adjustment of the pump itself in the event that the site is in the wrong position。
Alternative options are also considered for corrosive or corrosive liquid pools. For example, the need for spare pumps for key positions, the pre-positioning of vulnerable items and the availability of security space for decommissioning. The more special the non-targeting equipment is, the more it cannot be considered only if it can be made and whether it can be recovered quickly after it has broken。
If a mixer, slurry or other equipment is present in the pool, it is also necessary to confirm whether the location of the pumps will interfere with each other. In case of a conflict with the inner structure of the pool, the handling of non-sampling sub-pumps can be cumbersome. Prior to customization, high-level clearance of in-pool barriers, overhaul platforms and suspensions is more reliable than later repairs。
The sooner these details are confirmed, the less work is done on non-platform processing and the easier it is to install on-site。
A simplified review of the programme may also be undertaken, if necessary, to confirm the liquid position, depth and direction of the fluid before finalizing the drawings。
The key to a non-standardized long liquid slag slurry pump is to “longer” the service to stabilize the pump, rather than to satisfy a surface specification. When participating in such programmes, the quartz-pumping slag-pumping industry should be more explicit in terms of liquid pool structure, axial stabilization, material boundary and overhaul. These issues are cleared in advance, and it will be easier to install, operate and maintain when customized pumps are deployed to the field。
