ZX series self-priming centrifugal pump installation

First, the direct drive pump and the motor is, you should pay attention to the coaxial output shaft and motor; pump installation accuracy or not on the smooth operation of the pump and have a greater impact on the service life, it must be carefully installed And correction. Second, the pump coupling must be tight with a spiral, and locking nut, beware of nut loose, or easily lead to impeller movement, resulting in mechanical failure. Third, 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. Fourth, the suction pipe installation should pay attention to: (1): suction inlet installation height can not rise 3.5 meters, when conditions permit, suction inlet installation height should be as far as possible below the pool of the most artificial storage level, and as far as possible Shorten the length of the suction tube, less elbow, this will help shorten the self-absorption time, improve self-absorption function. (2): valves, flanges, etc. in the suction line should be strictly prevented from leaking or leaking liquid, that is, suction line should not be allowed to leak. (3): The solid body and other sundries should be prevented from being inhaled in the pump body. Therefore, a filter should be installed on the suction pipe. 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. Fifth, when the pump is installed, the electrostatic grounding resistance of the pump and the pipeline should meet the requirements. Sixth, the installation should be strictly checked pump shell and pipeline electrostatic grounding resistance to meet its requirements. Seven, correction of pump coupling and motor coupling installation of the gap and coaxiality, its different axis tolerances of 0.1 mm. Pump shaft and electric shaft height difference in the foot pad copper or metal skin adjustment. Eight, the actual operation of the unit 3-4 hours later, 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, bearing body temperature should not exceed 70 ℃. Nine, the pump bearing body cooling unit with a cooling water connector for the hole with Φ12 hose or plastic pipe, the thread size M12 × 1.25. X. If the pump is equipped with a one-way valve on the outlet pipe, the pump can not discharge the gas smoothly during self-priming. The exhaust pipe and valve should be connected to the outlet of the pump.

Stainless Steel Sliding Door

Characteristics and Advantages

(1) Intelligent control design: adjustable main parameter and secondary parameter automatically according to the weight of door leaves;

(2) Low noise: Special static sound track, integration of motor, worm-gear and retarder.

(3) Anti-clamping function: automatically reverse when meeting barriers;

(4) Unique electronic motor lock: the motor will lock up when the door is forced to open.(controlled by remote or switch)

(5) Tighten force: seal door when closed, power consumption approximately 10W under standby;

(6) Advanced brushless motor(36V,100W) can automatically adopt different heavy door leaves;

(7) Bi-doors inter-locking: one of the door leaves always remains closing;

(8)Safety sensor terminal: sensor stops working when door closed;

(9)Unique coating technology: never rusty;

(10)Easy and convenient to install;

(11)Working Process: when the door leaf closes to the right place, the door leaf will slightly shift to the door frame and the ground. The rubbers on the four sides of the door leaf will completely combine with door frame and ground, which ensures air tightness. When the door is open, the rubbers will separate from door frame and ground, which avoids contraction on the ground.

Technical Details:

(1) Rubber lining sealing technology combined with V groove on the guide rail enables the door completely sealed when the door closed;

(2)Special door body location technology. Semicircular surface beam on the ground matches with the V style groove at the bottom of door leaf, which stop the door from swing and make sure it moves stable and smooth;

(3) The door body decorated with matte stainless steel or spray surface, and on the middle and both sides with sealing stripes to ensure the hermetic effect.

(4)Feet sensor switch applied to avoid contagion;
