[Asia Pump Network News] how electric reciprocating pump classification, what components? Today, Xiaobian want to share with you is the content of electric reciprocating pump classification and composition, to understand these, we will know the main function of the various parts of the electric reciprocating pump and how it works. Below, we look at the specific introduction of it, after reading, you will have a new understanding of the electric reciprocating pump. Electric reciprocating pump according to the use of occasions and the different transmission medium can be divided into general and special, special electric reciprocating pump two categories. Below, Xiaobian mainly introduce the general electric reciprocating pump. Most electric reciprocating pumps are mostly piston type, usually horizontal and vertical two types. Classification and composition of electric reciprocating pump General horizontal electric reciprocating pump is mainly composed of a direct transmission of liquid pump cylinder part and the reciprocating piston piston reciprocating motion components. Pump cylinder is mainly composed of pump body, piston, sealing device, suction valve and discharge valve. Reciprocating pump cylinder structure has two types of DC and ladder: DC pump cylinder, the suction valve is arranged in the bottom, the discharge valve is arranged above; stepped pump cylinder, the suction valve and the discharge valve into a 90 ° ladder Arrangement. Reciprocating pump cylinder withstand liquid pressure, it does not allow the presence of pores and cracks and other defects. Pistons is to change the studio volume and suction, an important component of liquid discharge, divided into two kinds of disk-shaped piston and piston. Disk piston assembly, mainly by the piston, piston rod and seal components. The seal is usually made of cup, packing and piston ring; the sealing device of the piston rod is sealed with packing seal and seal ring; the column piston has only one plunger rod and is directly matched with the reciprocating pump cylinder. Suction valve and discharge valve is to ensure liquid one-way flow device, a spring valve and gravity valve two: spring valve generally consists of valve seat, valve disc and spring and other components, the valve seat and valve disc contact surface with a flat and tapered , It is also called flat valve and cone valve, they are relying on liquid pressure through the opening to open, relying on the valve itself and the spring force to close; ball valve is a kind of gravity valve, it is also through the flow of liquid pressure Open, but only rely on the weight of the ball itself to shut down. Crankshafts are an important part of the entire transmission. Different types of pumps have different crankshaft types. The connecting rod is a connecting member that makes the rotary motion reciprocating. The crosshead is used to connect the connecting rod and the piston, and together they form a set of crankshaft connecting rod mechanism. In order to make the flow uniform, electric reciprocating pumps are almost double-cylinder double-acting type. In addition, the electric reciprocating pump cylinder near the upper discharge pipe is usually equipped with an internal closed air chamber, so that the entire discharge process to further balance the flow and maintain a certain value. Vertical electric reciprocating pump internal structure and horizontal the same, but the reciprocating pump cylinder vertical arrangement. General motor and transmission part is located in the upper part of the reciprocating pump, pump cylinder is located in the lower part of the transmission part and the pump cylinder with four steel columns connected into one, and fixed on the pump seat. Vertical electric reciprocating pump supporting the main ship to exclude the bottom water, cargo, oil and auxiliary boiler feed water. On the electric reciprocating pump classification and composition of the relevant information, Xiao Bian introduced to this, the article mainly describes the composition of the general electric reciprocating pump, the role of each component and work, elaborate or more detailed, we can take a moment to understand in depth under.
