The explosion-proof pump is a kind of volumetric pump with vacuum suction and squeeze discharge, which has some unique characteristics. Since its invention more than 60 years ago, it has been widely used in various industrial and mining situations.
The working principle of
There is an eccentric convex block in the pump chamber. When the flexible blade leaves the eccentric block, the volume between the blades increases continuously and produces a vacuum, which causes the liquid to be sucked into the inlet of the pump cavity continuously.
When the flexible blade rotates, the liquid is brought into the discharge part by the suction part of the pump chamber.
(3) when the flexible blade in contact with the eccentric convex block again, bending, and accompanied by a squeezing action, make the liquid continuously, without pulse discharge pump cavity, so as to finish the whole course of suction line.
Flexible elastomer technology of impeller.
As the core technology of flexible pump, the impeller of the pump should have good elasticity, small permanent deformation, and can withstand the long and high frequency flexion without breaking and tearing. The excellent performance and durability of the pump is determined by the excellent impeller elastomer technology. There are two kinds of materials: mdash; & ndash; Hygienic butyronitrile rubber, epdm; The butyronitrile impeller is mainly used in the fields of vegetable oil, mineral oil, oily media and hygienic requirements. It is mainly used for weak inorganic acid, organic acid, alkali, salt, alcohol, ketone, sewage and other widely used media.
The characteristics of
In general, small size and large flow rate, compared with competitive pump, the minimum volume of the same flow. Easy to install and move.
Introduction of explosion-proof pump.
Instant complete self-absorption — No additional device is required. No priming is required before starting. The suction can reach five meters.
The pump body is made of stainless steel, all of which are stainless steel (1Cr18Ni9Ti) s304 or S316L.
The viscosity of the transport medium can reach 5000 cm.
It can convey gas liquid, foam liquid and no gas resistance.
It can deliver medium of suspended soft and hard particles.
The gentle motion of the rotor does not damage the medium that is sensitive to shear, such as paper dispersant.
When the flexible rotor is running without metal contact, there is no spark; It is especially suitable for the transportation of alcohol, gasoline, acetone and other solvents.
Beautiful appearance, durable, easy to maintain.
application
The outstanding self-priming pump performance and strong adaptability to the working conditions of applied in all kinds of industrial situation, carries on the inverted bucket, warehouse, underground tank of liquid pool suction row, sampling and various, viscid fluid conveying, such as inverted bucket only need to import the hose inserted into the barrel can be smoked light static. It is widely used to replace centrifugal self-priming pump, liquid pump, gear pump and so on.
