ZX series of water self-priming pump installation methods
As the user's lack of understanding of the pump, the installation is often used because the installation method does not lead to normal pump out of water, so buy the pump user is necessary to understand the pump installation method. Xiaobian now introduce ZX series water self-priming pump installation method. ZX series water self-priming pump section structure ZX series water self-priming pump installation method 1, the pump and the motor direct drive is, should pay attention to the coaxiality of the pump shaft and the motor output; pump installation accuracy or not on the pump operation Smoothness and service life have a greater impact, it must be carefully installed and calibrated. 2, pump coupling must be tight with a spiral, and lock the nut, beware of nut loose, otherwise easy to cause the impeller to move, resulting in mechanical failure. 3, in order to pump the body to maintain a certain amount of storage solution, in order to achieve better self-priming capacity and prevent mechanical seal dry friction, the pump must be imported higher than the shaft centerline. 4, the suction pipe installation should pay attention to: ①suction inlet installation height can not have played 3.5 meters, when conditions permit, suction inlet installation height should be as low as possible pool tank the most artificial storage level, and try to shorten the suction pipe The length of less elbow, this will help shorten the self-absorption time, improve self-absorption function. ② suction pipe in the valve, flange, etc. should be strictly prevent leakage or leakage of liquid, that is, suction pipe does not allow the existence of leaks. ③ should prevent the inhalation of solid body and other debris pump, this suction pipe should be set on the filter. The effective flow area of ​​the filter should be 2-3 times the suction pipe cross-section, the filter should be checked regularly. ④ suction pipe and discharge pipe should have their own support, the pump itself is not allowed to withstand the load pipe. 5, the pump is installed, should make the electrostatic resistance of the pump and pipeline to meet the requirements of its grounding resistance. 6, the installation should be strictly checked pump shell and pipeline electrostatic grounding resistance to meet its requirements. 7, correction of pump coupling and motor coupling installation clearance and coaxiality, its different axis tolerance is 0.1 mm. Pump shaft and electric shaft height difference in the foot pad copper or metal skin adjustment. 8, 3-4 hours after the actual operation of the unit, for the final inspection, if no adverse phenomena, then that the installation has been properly carried out in the test run should check the bearing temperature, the bearing body temperature should not exceed 70 ℃. 9, ZX Series Centrifugal Self-priming Pump Bearings All the cooling water fittings equipped with cooling chamber devices are provided with a hose or plastic pipe with a bore of Φ12. The thread size is M12 × 1.25. 10, If the pump outlet pipe is equipped with a check valve and in the process of self-absorption can not make the pump discharge gas smoothly, add the exhaust pipe and valve at the outlet of the pump.

Realistic pen and ink painting is a pen and ink painting creation using realistic techniques, which is essentially different from all previous pen and ink paintings. In the past, there were signs that one kind of "work" served another kind of "work". The nature of its existence seemed to have no independence "forever". Even if some works had strong independence, they could not get rid of the fate of "attachment". Realistic pen and ink painting is different. It is independent. Its existence has no "dependency". Its existence itself is its ultimate result.
