Mud pump is also a popular concept of a broad pump. The different regions, habits, and ultimately the pump type will not be the same. The mud pump described in this entry is a pump type in the most sense: oil drilling The applied mud pump. In fact, some non-clean water pumps such as sewage pumps, slurry pumps, and mud pumps are also commonly used when they are called. This entry explains to readers the mud pump in the drilling field.
Introduce the drilling machine to transport slurry such as mud or water during drilling. Mud pumps are an important part of drilling equipment. In the commonly used positive circulation drilling, it is to flush the surface rinsing medium—water, mud, or polymer rinse fluid—through a high pressure hose, faucet, and the center hole of the drill string directly to the bottom of the drill bit under a certain pressure to achieve Cools the drill bit, removes the cut rock debris and transports it to the surface. The commonly used mud pump is piston type or plunger type. The power machine drives the crankshaft of the pump to rotate. The crankshaft drives the piston or plunger through the crosshead to reciprocate in the pump cylinder. With the alternating action of suction and discharge valves, the purpose of pressure feed and circulating rinse liquids is achieved. Mud pump classification Mud pumps are divided into two types: single-acting and double-acting. The single-acting type performs only one suction and drainage operation in one cycle of piston reciprocating motion. The double-acting type completes two suction and drainage actions every time it reciprocates. If classified by the number of cylinders of the pump, there are three types of single-cylinder, double-cylinder, and triple-cylinder.
Mud Pump Product Overview: The I-1B thick stock pump is a single screw type volumetric rotary pump. The I-1B type thick stock pump uses an eccentric single screw screw to rotate in the double helix bushing, so that the thick liquid slurry is sucked along the spiral groove. The mouth is pushed to the discharge port to realize the pump conveying function.
Mud pump features:
1. It can deliver high concentration, high viscosity <10000PaS and suspended slurry containing particles.
2. Stable flow, no over-current, pulsation and stirring, shearing slurry phenomenon.
3, discharge pressure has nothing to do with the speed, low flow can also maintain high discharge pressure.
4. The flow rate is proportional to the rotation speed, and the flow rate can be adjusted through a variable speed mechanism or a speed-regulating motor.
5, self-priming ability, do not have to install the bottom valve can be directly pumped liquid.
6, the pump can be reversed, the flow direction of the liquid is changed by the direction of rotation of the pump, applicable to the situation where the pipeline needs to be flushed in the opposite direction.
7, smooth operation, vibration, noise.
8, simple structure, easy disassembly and maintenance.
I-1B thick slurry pump is widely used in chemical, pharmaceutical, brewing, paper, food and other units.
Slurry pump structure Material type: I-1BB type: shell casting, transmission parts (spindle, screw and spool) made of stainless steel, suitable for general neutral thick slurry delivery, generally slightly acidic, alkaline slurry delivery.
Type I-1BF: The pump housing of the transmission and the contact slurry are made of stainless steel and are suitable for the transportation of food, pharmaceuticals and corrosive slurries.
Rubber bushes are generally wear resistant rubber, food rubber and oil resistant rubber for the user to choose.
The transmission mode has the direct drive of the motor and the pump shaft. The motor is directly driven by the speed reducer and the pump and the motor is driven by the triangle belt pulley and the pump shaft.
Equipped with a general closed motor, explosion-proof and electromagnetic speed control motor and with continuously variable speed, gear reducer for the user to buy.
CNI offers proper Laser goggles that protect from laser damage. The lenses are constructed to seal absorbent dyes * in rigid polycarbonate to provide excellent crack resistance and prevent subtle scratches from affecting laser protection.The optical density (OD) and LB grades of a particular wavelength range are printed on the lens or frame and cannot be erased for permanent recognition without blocking the view.
Features:
Absorbent dye sealed in rigid polycarbonate lenses (not brittle)
Surface scratches do not reduce the optical density of the lens
Reasonable and affordable protective goggles
High level optical density (OD value)
Lineup that can be selected according to the type of wavelength and laser

About optical density (OD value: Optical Density)
A laser filter that blocks a specific wavelength of laser light becomes safer to the eye as the transmittance becomes zero.
Optical density (OD value) expresses the degree of absorption as a logarithm.
The higher the optical density (OD value), the higher the safety.
For example, if a CW 1kW laser beam is transmitted through laser protective glasses with an OD value of 6, it will be 1mW.

About VLT (Visible Light Transmittance)
Indicates the transmittance of visible light. To the human eye, the higher the VLT value, the brighter it looks, and the lower the VLT value, the darker it looks.
