GN Vacuum pump is a good transfer way for solids control area

For vacuum pump service life longer, maintenance is the key segment to guarantee the vacuum pump running properly. It should be frequently to check and maintain the vacuum pump according to the instruction book. every vacuum pump package,this is the main measure to reduce the down time of the vacuum pump and keep equipment running properly all the time.

Points for maintenance

Requirement for maintenance staff

Should designate the technician who was trained with the vacuum pump technology to operate, manage and maintain the vacuum pump.

It’s only allowed for the designated and trained staff to operate and maintain the vacuum pump, and operate the equipment properly, strictly according to the operation use and maintenance procedure’s requirement

Purpose of maintenance

Vacuum should be periodically checked, maintained and serviced to guarantee the function and key parts and safeguard procedure of the vacuum pump under normal condition. And guarantee the vacuum pump working under good conditions and the guarantee the mechanical property and technical characteristic of the vacuum pump. Prolong the equipment longevity and lower the usage cost.

Maintenance method

A large scale maintenance should be done every 3 months, inspect the tank body, the usage of the combination of feed and suction pipe and discharge pipe, if found they are severely damaged,should exchange immediately.

Inspect if the exterior fasteners of the equipment are fastened properly once a month (600 hours)

Inspect the brake valve of air cylinder once a month(600 hours), if the movement is

flexible, if there is air leaking or water leaking, if there is block or leakage, should fix immediately.

Drilling fluid was necessary for oil&gas drilling system,in some big HDD/TBM system,it was needed too

For the mud system’s design we need consider item as below:

1.hydrocyclone(desander/desliter)

When particle running at tydrocyclone,it will damage inwall of cone,normally the desander/desilter was made my metal material like gray iron or stainless steel,is hard enough,but service life will be short when treating some special mud,and fall off metal will effect density of mud,not suitable for some project

GN choose high quality PU material desander/desilter,to keep unit’s service life long enough,and keep mud’s state well

2.fluid surcafe balance

Most tank in solids control is top open design,the mud will freely move when overflow,GN have negative direction overflow design,untreated mud can’t move into clean mud,keep drilling work stable

3.cutting point

In some mini mud system,we will choose double deck shaker for solids control,the mesh’s choose was not like regular compound mode,the top deck need treat mud after hydrocyclone,the size should be small,the bottom deck is for untreated mud,size was bigger

4.total capacity

The mud cleaner can treat most mud and same tank’s top space,but in some condition,the solids part will carry more fluid after cleaner,because of not enough screen area,so in some deep drilling system,The desander and desiliter shoud install in different shaker,to keep treated solids more dry

5.tank volume

Some big dproject will need more fluid to support drilling,we will design longer storage tank,but with volume raise,the agitator/mud gun’s choose should be more,to keep mud mixing enough,like agitator’s impellar quantity will be 2,mud gun’s connect size should raise ,make mix power enough

GN will keep develop mud system,to bring better product for client

Shocking protection for solids control transportation is very important for equipment use,GN treat it seriously to give client best product

Most solids control equipment is working by physical way,and running by motor and bearing

For keep equipments running well and long service life,before shipment or transportation,must do necessary fix way to keep equipment stable,like decanter centrifuge/shale shaker/vertical cutting dryer

The shale shaker’s spring of basket is designed for work,when shipping by air/sea/truck,the sudden joit will damage it and the maintenance will need many cost and time

Most important work point of centrifuge is balance,if fixing bowl by bracer,it can keep main screw and bearing stable when transportation,raise service life of whole unit

Same like vertical cutting dryer,the most equipment related about motor and bearing,need keep stable state when transportation,to make sure the parts not damaged and keep balance

Some user didn’t know the shocking protection design of equipment,and cause the service life become very short by moving,so,the best way is apply the equipment supplier arrange engineer to jobsite and make lesson for everyone,it totally worth it,to reduce maintenance cost and better treatment result

There is some special shocking protect way like use deck to fix,like photo attached, Vertical cutting dryer with Mounted in a metal pallet during shipment,the pallet will remove when installing at skid

GN solids control will use professional design to give best protect for equipment,let client get perfect product

 

GNSP Sludge Vacuum Pump is able to produce high vacuum up to 25”HG (Mercury Column) for transfer liquid, drilling cuttings, sludge and solids.

The pump is without any rotation items. With special structure design and powerful suction capability, it can be used at tough environmental for solids transfer, high working performance and less maintenance

It’s very important to learn right way to use the equipment,below was photo explain of vacuum pump

Manual control and setting of time controller

 

All valve will not move(open or close) after finished set 2 switch levers

Control switch lever as same as Form1,based on different use way and request，valve will change follow switch lever

Work mode	Manual loading	Manual unloading	Auto
A/M Switch lever	Switch to Manual	Switch to Manual	Switch to Auto
L/U Switch lever	Switch to Loading	Switch to Unloading	Switch to Default
Gas gate valve	Open	Close
Feeding gate valve	Open	Close
Discharge gate valve	Close	Open
Gas jet tube ball valve	Open	Close
Discharge tube ball valve	Close	Open
Pressure number (Mpa)	>0.55Mpa	>0.55Mpa
Time	test until 70%	test until empty
Form 1

1.When loading mud,computing the time between vacuum tank empty to 70% full,to set L time controler

2.When unloading mud,computing the time between vacuum tank 70%full to empty,to set D time controler

3.The auto mode can go on when manual mode running well，control switch same to form1’s auto mode set
