The normal issue of GN Solids Vacuum pump

GN solids vacuum pump is one of our most featured equipment. It was totally developed by GN. Currently, only 3 suppliers can provide this kind pump in all over the world. And GN is only the China company. Every year, we export more than 200 units pump to all over the world, and this quantity keep raising every year.

Different with normal pump, GN solids vacuum pump driven by pressure air provided by air compressor. And this pump can transfer dry solids that smaller than 75mm , and it is good at pump high solids control material such as drilling cutting ,sludge that the normal pump can not pump. The special application makes solids vacuum pump become one of the most popular equipment in market. Vacuum pump does not have complex structure, only one mud tank with several air control valve. Utilize the high pressure to make a vacuum space in mud tank inside, and then suck material into tank. Finally input air into mud tank to push the material to discharge out. This simple structure is also one the bigger advantage of this pump,more simple structure,more stable quality.
However, this pump still wold be some issue after long time using. Most times, these problem was caused by the dirty air. Even there is air filter inside the vacuum pump ,but some things dirty still may block air line of pump. Inside of control box, there is one 5-way valve ,which is used to Switch air flow direction to control material loading and uploading. When the pump do not work well, Most time it was cause by the blocking of 5 way valve. Client can disconnect the hose of top and bottom valve. And then connect air source, through high pressure to blow out the dirty inside of the valve and finish the valve cleaning. Finally, return the hose position and run the pump again.

Most times, we can solve the pump issue through cleaning 5 ways valve. If the cleaning is useless ,you can contact GN , and we will give out the suggestion to help you solve this issue.

GN Mud Station Project in America

In most drilling project, client made mud at job site. But there is also special mud company, they made mud and store them in big mud tank.When client need drilling mud ,they directly ship these mud to the drilling field. Usually ,mud station need big plant to lay huge mud tanks. These tank can store drilling mud , clean water, cement etc to made different type mud for drilling well using.

Most times, client will choose local tank manufacture to make these tank ,but some times, the material grade, the processing technical can not reach the customer requirement ,and this may cause the short life time of mud tank. other aspect ,mud station also need other kind solids control equipment to mixing mud and treat them , such as mud jet mixer, centrifuge pump, shear pump, Decanter centrifuge etc. The complex requirement to manufacture and equipment make there are less company can provide all things for a mud station. GN solids control is one of these company that have ability to provide a whole solution to customer to built mud station. From tank building to equipment assembly.

As we all know GN factor is located in China. To foreigner client, transport is a big issue and higher fees to ship these tank from China to their local. Consider all factors , such as manufacture time, processing technology, price , more longer time products, the cost of using actually is better than choosing a vendor who are short experience in these mud station project. Client trust GN and very satisfied to our service. From design to manufacture, and give out solution to transport, GN own a entire solution to help client built their mud station.

If you have project similar like mud station, such as waste water treatment, mining slurry tailer processing, river dredging project, HDD, TBM etc. Like these project need to treat the drilling mud , we will be pleased to provide the whole solution for your project.

GN Vertical Cutting Dryer and Screw Conveyor for Drilling Company

GN Solids Control has served oil gas industry for more than 13 years. We mainly produce solids control equipment for drilling mud treatment and also the drill cutting process. Last month we just shipping one cutting dryer and screw conveyor to Africa to oilfield drilling field.

The drilling mud carry lots solids from well, after separation by the shale shaker. The clean mud will return back to mud system for drilling again. But the discharged drill cutting from shaker still very wet, which involved lots of drilling mud. As we all know drilling mud has lots high pollution chemical material, it can continuously influence the soil for many years, and drilling mud is very expensive. So we need to recycle these drilling mud as much as possible to reduce the pollution to environment and also save the cost of mud.

In this African project , screw conveyor can directly catch the discharged solids from shaker and transfer it into vertical cutting dryer. Inside dryer, there is cone shape basket with opening hole. Motor will drive the basket and generate separation force. Although solids and liquid both bear the separation force, but solids can not go through the opening hole, because the diameter is higher than the basket hole. The liquid mud will go through the basket and be collected. The primary is similar with dry function of washer. Dewatered solids will down to bottom of dryer and transport away for further process.

As usually, vertical cutting dryer is used for oil base drilling mud. Sometime client use it for water base mud, the solids may block the opening. So we do not suggest client use it for water base mud. After treatment , 95% percent of drill mud can be recovery. However the recovered liquid need to be further treated by decanter centrifuge to remove out bigger size particle, and then turn back to solids control system.

GN not only provide equipment, but also good at customize system, if you have the similar project, welcome to contact us.

Dewatering Equipment Delivered to Environment Company

Last week , a Latin America environment company focused purchasing several dewatering equipment for their project. The are screw press dewatering machine , Decanter centrifuge and chemical dosing unit. As one of the earliest separation company in China, we have more than 15 years experience on manufacture and equipment development. We exported equipment to more than 76 countries. Till now, GN own 3 manufacture foundation. Equipment application include oil gas, food beverage ,environment industrious. And environment sales is raising quickly. And we are also put more effort on the environment industry and serve our customer.

In these equipment we sold to customer. All these equipment are small treating capacity and mobile unit. Such as the decanter centrifuge. Client take it to the job site for some small treating capacity project, customer do not need to transport the waste into water plant. The decanter can process it well at job site. Which also equipped a bottom tank as buffer to convent customer to connect other equipment for further treatment, because the Decanter centrifuge is not good at separating the particle size smaller than 5um.

Client also purchased 1 unit 201 screw press dewatering machine and 1 unit 202 screw press, the 101 model equipped 1 500L/hour chemical dosing unit to feeding polymer. Screw press dewatering machine is good at separate out the material that solids content less than 5%, especially in some soft bio material. But if the particle is too small smaller than 10um. It is hard for machine to separate, we need to polymer to combine small particle to big one. The automatic chemical dosing unit can adjust and feeding medicine to material ,and help screw press to get better separation effect.

Our advantage is providing customized solution for customer, include select the optimal equipment model to solve problem and save money, and the solution must friendly to environment. If your have similar project demanded to solids-liquid separation, welcome to contact us.
