Abstract
The utility model relates to a filtering device of a chemical pump, which comprises a pump body and an inlet pipe, wherein the inlet pipe is connected to the inlet of the pump body, a filter is arranged on the inlet pipe, the filter is a filter bag, the filter bag is mounted below the inlet pipe through an adapter, and one end of the filter bag extends into the inlet pipe. Through the adoption of the filter with simple structure, the utility model can effectively filter off impurity in the liquid, so as to prevent the impurity from entering the chemical pump, prolong the service life of the impeller, ensure the seal performance and improve the availability of the chemical pump.
Description
Technical field
The utility model relates to a kind of chemical reactor, particularly a kind of chemical pump filter.
Background technology
Chemical pump is a kind of liquid material conveying equipment that is widely used in chemical field, mainly based on centrifugal pump, is applicable to and extracts corrosive liquids in container.Its operation principle is: before the turn on pump, must be full of liquid in suction line and the pump, behind the turn on pump, impeller rotates at a high speed, and liquid wherein is along with blade rotates together, under action of centrifugal force, fly away from impeller and outwards penetrate, the liquid of ejaculation speed in the pump case diffuser casing is slack-off gradually, and pressure increases gradually, from pump discharge, discharge pipe flows out then.At this moment, in the blade center owing to liquid forms the vacuum low-pressure district that does not only have air but also do not have liquid around being thrown toward, liquid in the liquid pool is under the atmospheric effect of pond face, in the suction line inflow pump, liquid comes to this and continuously is pumped up from liquid pool and continuously flows out from discharge pipe.When containing a large amount of solid impurity in the liquid, these impurity are the bump impeller constantly, and impeller surface is damaged gradually, influence operating efficiency, when serious even stop up firmly impeller channel, reduces delivery side of pump pressure greatly; Impurity also can impact the sealing of pump in the liquid simultaneously, and pump is leaked.
The utility model content
Technical problem to be solved in the utility model provides a kind of simple in structure, can prolong the chemical pump maintenance cycle, the filter of protection chemical pump operate as normal.
A kind of chemical pump filter described in the utility model comprises the pump housing and inlet duct, and described inlet duct is connected on the inlet of the pump housing, it is characterized in that being provided with on inlet duct filter.
Above-mentioned filter is a filter bag, and this filter bag is installed in the inlet duct below by interface, and filter bag one end stretches in the inlet duct.
The utility model is by using this filter simple in structure, and effectively the impurity in the filtering liquid does not enter in the chemical pump it, has prolonged the service life of impeller, has protected sealing, has improved the serviceability rate of chemical pump.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, a kind of chemical pump filter comprises the pump housing 1 and inlet duct 2, and described inlet duct 2 is connected on the inlet of the pump housing 1, it is characterized in that being provided with filter on inlet duct 2.This filter is a filter bag 3, and this filter bag 3 is installed in inlet duct 2 belows by interface, and filter bag 3 one ends stretch in the inlet duct, and interception filters out impurity in inlet duct 2.The interface of filter bag 3 is fixed with screw, cleaning filter bag in back for convenience detach.
Claims (2)
1. a chemical pump filter comprises the pump housing (1) and inlet duct (2), and described inlet duct (2) is connected on the inlet of the pump housing (1), it is characterized in that being provided with filter on inlet duct (2).
2. chemical pump filter according to claim 1 is characterized in that described filter is filter bag (3), and this filter bag (3) is installed in inlet duct (2) below by interface, and filter bag (3) one ends stretch in the inlet duct.
