Difficulty on extracting and aspirating contaminated lubricants.

The purpose of the application is to simplify the aspiration and replacement of contaminated lubricating mixtures in the gearboxes and drive units present in the wind turbine generators. The maintenance operations foreseen on the wind generation devices are quite frequent. Particularly difficult is the extraction of a type of lubricant which has the consistency of a fluid grease which, once its tribological properties have been exhausted, is replaced also because it contains a significant quantity of contaminating metallic microparticulate generated by the normal wear of the mechanical components.

The dense and viscous consistency of the lubricant creates various complications for maintenance purposes. The biggest problem is the difficulty in aspirating the contaminated lubricants of the gearbox. Our customer experimented different solutions to solve problem without reaching the desired efficiency levels. The different type of pumps put into the test, did not meet expectations, or proved to be ineffective or even damaged very quickly.

Also involved in the affair we were asked to offer our solution. We proposed a pump that would certainly have been the ideal solution for the suction of contaminated lubricants. A HCP 15 peristaltic pump equipped with a very compact electronic speed variation system.

The peristaltic pump, a good solution.

The small unit is particularly light and manageable, easily lifted up to the wind generator’s nacelle. Once started, the large vacuum produced by the HCP 15 peristaltic pump allows the suction of contaminated lubricants and dense mixtures with simplicity. The possibility of varying the flow rate of the pump allows to maximize the performances according to the different viscosity of the sucked lubricating fluids.

The light and compact inverter that the pump is equipped with is managed with a practical keypad with very simplified functions to be used by any operator.

The pump naturally is selfpriming capable and does not damage if it works occasionally dry. The pump do not suffer any damage generated by the presence of solid metal particulate present in the lubricating mass. The machine fully met the expectations of the customer, who with a modest investment was able to equip himself with a definitive solution, easy to use and truly effective for the aspiration of contaminated lubricants.

A well-known company engaged in the manufacture and sale of chemical substances and products destined to the car industry and transport, needed new pump for transfer chemicals with characteristics that are very variable. The raw materials and the products made in the company are generally acidic or alkaline, dense or viscous, or very fluid, but with a tendency to determine phenomena such as foams. The operation which the pump has in charge start from emptying the tanks for the transfer to production, to dosing into the container of the medium and the large proportion.

It is ideal that a single pump will be able to fulfil all the needs, adapting to the individual characteristics of the fluid, without complicated operations of adaptation. Among the various needs, there is also to move easily the machine in the manufacture areas according to the needs of the chemicals production cycle.

The company chose a Hose Carrier of the HCP 5.0-speed electronically variable, with a dedicated trolley. The pump can ensure to get a range from a few hundred litres up to 12000 litres times, work with thick fluids without difficulty, or pumping fluids, which generate foams without start this unwanted phenomenon. The full chemical compatibility of the pump avoid to prepare the machine for different tasks.

Granules, abrasive suspensions that may be present in the products, or processing waste contaminated can be pumped without any damage to the pump.

The presence of the inverter programmable allows simple dosing or interfacing with the sensors or the logic of the system that will be defined for the purpose. With a single pump, and no changes you will be able to pump many chemical based products or finished products such as, acids, bases, detergents, surfactants, degreasers, additives, solvents, emollients, and lubricants. Of course, the different viscosities are not a problem, as well as the possibility of priming capability that is guaranteed to dry without damage in the case of normal or intermittently operation, . Not bad for a single pump.
