Shear pump is a kind of centrifugal pump no need safety valve at outlet. Below is reasons explained from function and pressure source.

Explain on Functions to confirm shear pump no need safety valve

Shear pump is a kind of centrifugal pump. Drilling mud get a certain amount of kinetic energy while leaving impeller under the impeller rotating centrifugal force. Mud also get some certain of pressure in the pump housing, the pressure does not vary with the change of time, pump outlet size, but only depends on impeller structure, size, and rotating speed. As the pressure at shear pump outlet is not vary per pump flow or working condition. It is no need to match safety valve.

Explain on pressure to confirm shear pump no need safety valve

Driving motor and shear pump connected directly with belt. Design speed of impeller is 2200RPM (max.). Under normal working situation, like for 60hz motor, max. speed of shear pump impeller is 1800rpm, much smaller than the design speed. The maximum pressure generated from high speed rotating of impeller centrifugal force is constant. The max. shear pump pressure is 0.47MPa. The outlet pipeline and pump casing can surely withstand the pressure. In this case, it is no need to match safety valve.

Even in the case of the outlet is blacked or the valve is closed, pressure generated from the impeller rotating is larger than pump outlet, drilling mud cannot be discharged, and circulated within pump housing under the rotating force of impeller. If the outlet is blacked or the valve is closed, and mud circulated within the pump housing for a long time, the worst condition is to increase the temperature of pump housing in some degree. The pump pressure will not increase. Therefore, it is no need for mounting safety valve in shear pump outlet pipe.

Water Well drilling is the activities of drilling a hole in the ground for the extraction of ground water for life or industry usage.

For fast movement after one water well and for another jobsite, more and more customer prefer Mud tank system on wheels for water well drilling, also named as trailer skid mud system or mobile unit mud system. 100 ~ 200GPM Mud tank system on wheels is the most normal capacity for water well drilling mud system.

General description of air compressor

The air compressor, also named as air pump. It is a basic equipment of modern industry. It is used to generate pneumatic power system. Air compressor can convert the original motion (typically an electric motor) into mechanical energy of the gas pressure; it is a device to compressed air get air pressure.

Air compressor is widely used in industry, like for painting, for cooling. It is also wided used in drilling rig site.

1) Air compressor can power for vacuum pump in oil and gas drilling rigs, especially for drilling waste management site.

2) Air compressor can be the air source of positive pressurized control panel used for oil and gas drilling rig site for hazardous area. Especially used for VFD centrifuge control panel.

There are many type of air compressor, like Fixed type, mobile type and closed type. And per the different design principle, air compressor can be divided into different types.  

Below are the most common types of air compressor

1) Displacement compressors –It is directly depend on changing the volume of gas to increase air pressure.
2) Piston compressor – It is a kind of Displacement compressors, the compression main part is a piston, the piston make reciprocate movement.
3) Rotary compressors – It is a kind of Displacement compressors, it compressed air by the forced movement of the rotating element.
4) Liquid – piston compressors – It is rotary positive displacement compressor, in which water or other liquid as a piston to compress the gas, and the gas be discharged.

General information of flexible rubber coupling

Flexible rubber coupling, is also called as flexible connection, Soft rubber connector, soft rubber joints, flexible rubber joints, flexible rubber joints , rubber shock absorbers. The flexible coupling is mainly composed of the inner and outer rubber layer, Kordeinlage (ply) and steel rings, they form tubular rubber, under high temperature and pressure, then after vulcanization molding and then combined with metal flange Lapped Joint sets together. It is widely used in fire, chemical, valves and other piping systems, noise from seismic effects, absorption displacement generated during the operation of the pipeline.

Application of flexible rubber coupling

Rubber flexible coupling is a kind of hollow rubber products used to connect steel pipes in mud system. It can also be used for pump connection, valves, and high vibrating pipes, and temperature great vary pipe.

It is a kind of pipe joint with highly flexible, high air tightness, chemical resistance and weather resistance. In oil and gas drilling field, it is widely used to connect tank pipelines, pumps and used between other kinds of steel pipes.

Features of flexible rubber coupling

1) It is with high density internal wall, can withstand high pressure, good elastic reshape performance.
2) Reduce vibration and noise. Light weight design , easy installation and maintenance .
3) The structure can reduce structure borne noise, absorption of vibration.

As the above features, flexible rubber coupling is widely used in mud solids control system, to connect pipes and connect pumps. And flexible rubber coupling is a wearing parts for solids control systems. It needs to be replaced occasionly to aovid aging.

Specially made high-capacity units for all drilling environments

gnsolidsamerica.com patterns, manufactures and operates a comprehensive line of advanced balanced-elliptical and linear-motion shakers for each onshore and offshore applications. Regardless of whether utilised as scalping, main or stand-alone units, our high-capacity USA shaker screen provide unmatched solids removal. All folks shakers can be found for sell or rental.

We pioneered the designing of shakers that occupy minimum rig area, but supply the muscle to care for large solids volume. In high ROP applications, our shakers maintain solids at bay, allowing your energetic drilling fluid to complete at peak efficiency.

In designing our suite of substantial performing shakers, we looked initially at back as they are going to be asked to accomplish. Because drill solids degrade quickly when 1st processed, it is actually crucial they speedily be eliminated from your circulating mud. And that is where the shaker screen comes in, going for a critical position since the 1st mechanism for solids removal. Failure to be solids from the active mud could suggest diminished ROP, equipment harm, non-productive time and higher prices. In developing our shale shaker technologies we thought of:

The shaker vibration pattern

Vibration dynamics, or G-force

Deck size and configuration

Shaker processing efficiency

Shaker screen characteristics

What resulted are a great deal of a great number of innovative, large performing and cost-effective shakers across industry.
