1. Structure of 3 NB Series Mud Pump Description

The power end: The housing is welded steel-plate construction. It is stress-relieved after welding. The drive gears ate in volute type gears which allow smooth operation, high efficiency and long life. The crankshaft is a hollow one-piece steel casting. The power end is splash-Lubricate.

The fluid end: The suction and the discharge flanges conform to ASA and API specification.

The piston rod is connected with an intermediate rod by means of clamps to realize quick assembly & disassembly.

The valve seat bores have a bottom shoulders. The pistons and loners are lubricated and cooled by an independently spraying pump to have a longer service life.

Versatility in expendables

Q: The water tank of the fish tank does not air out and only has the water outlet: The air inlet pipe is connected with the oxygen burst, the entrance also pulled out, we can see that it is the design of a miter, the oblique incision back to the direction of the water flow speed, this outflow, negative pressure is formed in the oblique incision, the air can be sucked in. As shown.

Q: The difference between diaphragm pumps, vacuum pumps and centrifugal pumps: The function of vacuum pump is to make vacuum, which has many kinds of structure, such as centrifugal, diaphragm (diaphragm), piston, liquid ring, rotary plate, jet type...................

Q: I would like to ask, constant pressure pump set pressure 20Mpa, the actual load is 15Mpa, then the constant pressure pump outlet pressure? If it is 20Mpa, then where is the loss of 5Mpa? If 15Mpa, the constant pressure pump 20Mpa how to understand? In addition, the constant pressure pump pressure is defined when the flow began to reduce the point, or a sharp drop in flow after the point?: 15MPa. 20MPa means that if you enter the 20MPa, the variable mechanism will work, and the flow at this time automatically matches the load. 20MPa used to supply the fuel by maximum displacement.

Q: Excuse me, what is the water pump from the lotus root?: The utility model relates to a self coupling sewage pump, which is composed of a base, a self coupling frame, a guide rod, a guide rod, a support seat, etc., and the utility model does not need bolt connection

Q: Is the sewage pump the same as the mud pump?: No. the main functions are different:1, pump two main performance parameters is the displacement and pressure, displacement from a number of liters per minute, with the diameter and the drilling fluid requirements from the hole on the back end of the speed, the larger aperture, the greater the displacement

Q: Roots pump and dry pumpRecently involved in the work of the vacuum pump, don't understand this, is a ads602 vacuum pump, composed of roots pump and dry pump, is pre pumped to the 500mtorr equipment, the main pumping vacuum continues to 10mtorr, where the roots pump and dry pumps must be used? What role they play respectively. The so-called dry pump? Is refers to one kind of the pump, the pump is many dry pump? Also do not understand how the work of automatic switching system for pre pumping, the main pump, pump work alone did not connect system ah (of course there are even a butterfly) teach?: Different working conditions, our company does dry claw pump alone can also achieve the vacuum of 133 PA.

Q: How many pumps does the 80cm tank use?: Filter pump to select the water per hour can be filtered more than 3 times, I personally feel that this is almost enough. Of course, the more times the better, but also consider that if the pump is too large, the water inside the tank will be too large.128X3=384LThat is, the flow must be more than 384L/H of the water pump.You can buy a bigger pump, because the pump for a long time there will be some attenuation and domestic things in general to sign data, so it should be based on your actual situation to buy. Taobao on this category is about 20~40 yuan.

Q: When the water pump is started, why should it start when the outlet valve is closed? Thank you: When the valve is closed, the flow of the pump is close to zero, the power of the pump is very small, which reduces the load that the motor starts to bear and has a protective effect on the motor. Therefore, the valve closed to start the pump.

Q: What is the series of pumps? What is the difference between a unipolar and a multilevel? What is the meaning of each "first class"?: A single-stage pump is a pump with only one impeller. 2, a multistage pump is a pump with two or more impellers. The multistage pump can increase the pressure and lift the head higher. Level 1 means a booster impeller.
