Mud Pump Components and Spare Parts The structure is varied
Centrifugal pump is a kind of mud pump, a wide range of centrifugal pumps, the structure of a variety of centrifugal pumps must be combined with the suction tube and discharge pipe and other components together as shown in the pump device to work properly, the lower part of the suction tube There are filters and bottom valves that act as a filter for the liquid and prevent the liquid from flowing back to the suction tank. The discharge port is equipped with a gate for regulating the flow rate. The top of the volute is equipped with a funnel, the pump is used to pump water into the pump, the gas in the pump chamber is removed, or the pump chamber gas is pumped by a dedicated vacuum pump. Centrifugal pumps can also be classified by purpose, blade mounting, pressure size and speed ratio. For specific pumps, often give the necessary names according to their main features.
Mud pump is in the drilling process, to the drilling of mud or water and other washing fluid machinery. Mud pumps are an important part of drilling machinery and equipment. Let the mud pump accessories manufacturers to explain the next under the bar!
Its main role is in the drilling process with the drill bit into the drill down with the drill bit, plays a cooling bit, cleaning the drilling tool, fixed the borehole wall, drive drilling, and drilling drill back to the ground role. In the commonly used circular drilling, the mud pump is the surface of the rinse medium - water, mud or polymer rinse liquid under a certain pressure, through the high pressure hose, faucet and drill pipe column hole directly to the bottom of the drill to achieve Cooling the drill bit, the cutting down the cuttings and transport to the surface of the purpose. Commonly used mud pump is piston or plunger type, driven by the power machine crankshaft crankshaft crankshaft through the cross head and then drive the piston or plunger in the pump cylinder to do reciprocating motion. In the inhalation and discharge valve under the alternating effect, to achieve the purpose of pressure and circulation rinse solution.
Mud pump in the use of the process, pay attention to its sealing problem. Perhaps we all understand, there are three kinds of slurry pump seal, then the three ways to choose how to seal it? The following is the mud pump accessories manufacturers to introduce you.
On the choice of sealing methods, the most important thing is to first understand the characteristics of these sealing methods, and then according to the specific circumstances.
First packing seal, is the most common kind of seal, is injected into the shaft through the form of water, constantly filling a certain pressure inside the filler water, a pump body to prevent leakage: for not suitable for use with the impeller seal of the multi-level series Pump, with packing shaft seal. Packing shaft seal structure is simple, easy maintenance, cheap.
Followed by impeller seal, is through a reverse centrifugal force of the impeller, to prevent the slurry leakage. In the pump inlet pressure is not greater than the pump outlet pressure value of 10% of the single-stage pump or multi-stage series pump pump can be used to pay the first wheel seal, the impeller shaft seal without shaft seal water, Body, good sealing effect. Therefore, in the case where dilution is not allowed in the slurry, such a seal may be considered.
Again, mechanical seals are generally used in situations where the sealing requirements are relatively high. Especially in the field of chemical, food, not only require a seal, but most not to allow the addition of additional ingredients into the pump body. The disadvantage is that the high cost, maintenance difficulties and so on.
