a, newly installed self-priming pump have no suction is how to return a responsibility

new installation no suction self-priming pump is a great chance to import pipeline leakage caused by the reason, or the user during the installation process caused by pipe gets bigger, the inlet pipe is too long, it is possible that the user does not understand the use of the self-priming pump didn't give the reason of the water inside the pump cavity, another may be caused by the reason why the reversal of self-priming pump motor. According to several possible reasons for this given to find out why. Several reasons for this but we import pipe leakage reasons it is difficult to check, if it is steel pipe we suggest that the crackdown after welding test or negative pressure test before install and use, if it is the hose we recommend to mount the hard on both ends and in the middle of the exhaust tube is installed via a 3 connected ball valve and vacuum gauge, to form a complete set of a vacuum pump for pumping pressure test, the negative pressure suction to the limit after the exhaust tube in the middle of the ball valve closed and then observe the vacuum gauge whether there is the phenomenon of decline, if there is a decline in must have a flat place, then the need to observe if quiet environment can hear the sound of the leak will point to the pipeline inside inspiratory and particularly good, find leak point and repair.

here are to be highlighted some users in the use of common self-priming pump such as ZW self-priming pump and ZX self-priming water pump in meet without up liquid absorption, many users are accustomed to self-priming pump imports down by hand into the inlet to induction have suction, when hand in here find no suction self-priming pump is considered to be the problem of self-priming pump, actually this kind of method is wrong, you first need to know is this common self-priming centrifugal pump is not like Cheng Qi and vacuum pump suction speed is super fast, and the self-priming pump, it is only can use a fully closed conduit slowly to the inside of the pipe to the after certain negative pressure liquid smoke clean air can be sucked up, when you pulled down import pipeline is equal to the self-priming pump with atmosphere unicom, you use hand to induction, because have no induction have suction self-priming pump has remained a vast amount of air suction state he has produced no negative pressure.

if because self-priming height is too high, pipes, self-priming distance too long causes regular self-priming pump suction do not go up to the liquid, this kind of situation can change high self-priming pump suction pump products, such as vacuum assisted self-priming pump self-priming height can reach the level 9 meters, self-priming distance distance can reach 300 meters, and we also can put the conventional ZX self-priming pump and ZW self-priming pump set made without vacuum auxiliary also can achieve self-priming height 8 meters high self-priming pump suction products.

2, use for a period of time a little self-priming pump suction nor what is

use a period of self-priming pump if suddenly appeared a little self-priming pump suction also have no, then please check the self-priming pump chamber and the impeller have a jam phenomenon, there are many users of self-priming pump on the inner structure is not enough to understand and meet not water pump inspection after they dare not apart, so we recommend that users in use or to use operators should continuously grope for let also know how to check whether the self-priming pump chamber is a method of blocking phenomenon, such as ZW self-priming pump impeller there are a lot more after the impurities clogging is certainly no suction power, so when they need maintenance and close the valve of import and export the self-priming pump body in front of the drain bolt under open, put the water inside the pump cavity clean, then at the end of the motor bolt tear down, and separate the coupling, direct type only need to dismantle the motor base Angle bolts, then pulled down a circle above the pump cover bolts can move the bearing seat and impeller together to move out, after can see whether there are blocked on the impeller of sundry, ZW self-priming pump and ZX self-priming pump because at the beginning of the design not considering the convenience not clear clutter in self-priming water pump front cover design is a convenient and clean up the sundry small impeller cover plate, so I want to choose convenient clean up the sundry goods don't need to tear open impeller motor can choose the company's new strong self-priming sewage pump product is more suitable. Can be seen from the chart is:

need to know what you can refer to: strong self-priming pump

if the self-priming pump self-priming height can not meet the requirements can choose: diving sewage pump
