Centrifugal pump parts cleaning precautions

Pipeline centrifugal pump parts cleaning is a step must be carried out after the demolition work, after cleaning the parts, can be carefully examined and measured. The quality of cleaning work will directly affect the accuracy of inspection and measurement. Therefore, it is very important to do a good job cleaning. (1) Centrifugal pump cleaning appliances â‘  cleaning agent detergent should have strong detergency, volatile, non-corrosive, insoluble parts were cleaned and other properties. Commonly used cleaning agents are gasoline, kerosene, diesel and water-soluble cleaning agents. Gasoline decontamination strong, strong volatility, cleaning parts do not need to dry, it will quickly self-drying, is an ideal cleaning agent. However, due to the strong flammability of gasoline, poor safety, should pay attention to the use, in case of fire. Decontamination of kerosene and diesel is also very strong, but volatile as gasoline is good, the parts being cleaned often need to use cotton or rag to semi-dry. Lower cost of kerosene and diesel fuel, good safety, cleaning agent is widely used in maintenance work. Currently, the emergence of water-soluble detergents, due to its low cost, and has good decontamination performance, but also can save a lot of energy materials, repair work has also been widely used. However, water-soluble detergent foam in use, and not volatile, need to dry after cleaning. Oil box Oil box is full of cleaning agent containers. It is made of 0.5 ~ 1mm thick galvanized sheet metal, usually made of rectangular or round. The size of the oil box can be selected according to the size of the parts to be cleaned. â‘¢ brush and cotton yarn Brush and cotton yarn is dipped in detergent, parts for cleaning or wiping appliances. Brush common specifications (by width) with 19mm, 25mm, 38mm, 50mm, 63mm, 75mm, 80mm and 100mm and other. (2) l centrifugal pump cleaning precautions â‘  cleaning of parts and components, should be as clean as possible, with particular attention to cleaning the sharp corners or narrow grooves. â‘¡ When cleaning the rolling bearing, should first dig the grease inside the bearing, and must use the new cleaning agent, the rolling body and the runner on the inner ring and the outer ring should be particularly careful and serious. â‘¢ cleaning agent is mostly flammable materials, cleaning parts should pay attention to the process of fire prevention, so as not to cause a fire.

High Speed Door Motor And Control Box

Our company have German SEW Motor, Japan Mitsubishi Controller. Our own brand Hofic servo motor and controller. Chinese famous brand SEJ motor and Holip controller.

About our German SEW Motor and Japan Mitsubishi Controller: It is easy to find the ideal energy-efficient motor for your application at SEW. The series has a suitable design in its range for the globally applicable efficiency classes. Select the power and frequency within this motor design and you have already taken care of the most important selection criteria.All other motor options are of course available independently of the efficiency class. A comprehensive braking concept and cost-optimised built-in encoders ultimately complement the motor range. Comprehensive braking concept and combinations i.e. up to three different brake sizes per motor size featured in the range: Cost-optimised built-in encoders integrated into the motor. Motors for efficiency classes IE1 to IE4.Compact design saves space and costs. Future-proof, also as regards environmental protection (standards). Reduction in operating costs when using energy-efficient motors; our energy-efficient motors conform to the efficiency classes.

About servo High Speed Door Servo Control System: Our rolling gate servo control system is suitable for high speed and high usage soft and hard rolling gate. The whole system is in a small and light package, it has high torque and high operating speed, lower noise, high reliability, smooth and soft operating curves, it`s suitable for high speed and usage environment. The rolling curtain can be controlled by pull switch, push button, Bluetooth, ground radar, ground magnetic sensors. Operating Speed: 1M/s; Operating Width: <16 ㎡; Daily operating time: >2000 time; Rated voltage: 220v; Rated Output: 0.75 KW/1.5KW.

The system can operated via: 1) control box; 2) inching electronic control; 3) continuous automatic operation; 4) emergency stop; 5) single side operation box; 6) time delay; 7) ground radar and/or magnetic sensors. Please refer to Wiring Terminal for eternal connections.

System has fuse/safety wire shutdown switch for three-phase power protection, fuse/safety wire for operating circuit protection, and temperature sensing relay for motor protection.

Stroke Controller utilizes absolute value encoder. Connect the absolute value encoder and reducer via encoder`s axle, and fix the wings on to the reducer, than insert the aviation plug into plug receptacle.

The mounting screw for the control box must inspect regularly to prevent screw been getting loose and falling off. Check the internal and external wirings. Check and change the oil for the redactor on regular basis.

Precision: The system use Full closed-loop servo control and Double Encoder design. This is to ensure long operating life and to prevent overshooting during operating.

Stability: The system utilizes integrated design concept, in order to simplify internal wiring and prevent any function caused by wiring and terminal connections.

High Speed: Motor max speed is 2500 rpm; door max operating speed is 2 m/s.

Smooth: The torque servo system can adjust torque to the load automatically, and its speed curve mode step less speed regulating to ensure a smooth operation.

About SEJ motor and Holip controller: Three-phase asynchronous motor with magnetic brake has broad uses, It is suitable for various mechanical main drive and auxiliary drive, and it is also used for various required rapid stopping and correct positioning. The braking time within 0.2 second. Electric motor is added the DZM series direct current electromagnetic arrester by the basic series(Y series) electric motor.The protection class of electric motor part is IP44,the arrester part is IP23.if be applicable to bad environment can also make the arrester part into IP44,but customer have to put forward a special request while ordering,the manufactory can design a manufacturing exclusively. Its structure diagram is picture 1 and 2,picture 1 is the structure with hand release.Picture 2 is the structure without the hand release.Its operating principle BE, after being to make the retardation coil(6)to connect direct current power supply,because of the function of electromagnetic force,electromagnet(7)attract gag bit(5),and compress spring(24),make arrester disc(2)away from the friction surface of the gag bit(5)and shield(26)(the electrical motor can immediately operate normally).When the power supply cuts off after,the electromagnet(7)loses electromagnet force,the spring(24)releases the gag bit(5)and compress tightly to arrester disc(2),the arrester function,stop(the motor shaft)quickly,make electric motor shop turning to move,for the second time connect power supply will repeat above-mentioned action.
