Centrifugal pump operating procedures: 1, pre-boot preparatory work: Check the centrifugal pump and motor are in good condition, the bearing grease is in line with the requirements, the oil level is appropriate, the various parts of the screw is loose, the lack of disk pump 3- 5 laps, to see if the rotation is flexible and free, there are no noise in the pump, check whether the eccentric wear coupling, whether fastening. 2, check before starting the valve: the pump inlet valve are all open, balance pipe valve, balance pipe pressure valve is open, the pump bearing, packing box cooling water valve open and control the flow, check the pump outlet valve is Close, pump return valve is closed, open the pump outlet vent valve, the pump air to the net, and then immediately shut down. 3, start the operation: 1) Before starting the pump, electrician (high pressure centrifugal pump) must contact with the good, and let other people pay attention to safety, so as to avoid danger. 2) Press the start button, pay attention to the current changes. 3) Observe the pump pressure rise to the maximum pressure of the pump situation, the valve will slowly open the outlet to maintain a stable pump. 4) After starting, we must follow the method of listening, watching, touching, thinking and smelling. We should conduct a comprehensive inspection on the pump. If any abnormal situation is found, stop the pump immediately and check it out. 4, inverted pump operation: 1) Press the start of the inspection and start the operation steps to start the backup pump. 2) After the standby pump is started, the valve should be shut down slowly, and the outlet valve of the standby pump should be slowly opened at the same time so that the pressure fluctuation in the main line can be controlled within the specified range. Stop the valve according to the requirements. 5, stop pump operation: 1) the pump outlet valve slowly closed. 2) pay attention to the main line pressure, dry pressure to maintain stability. 3) Press the stop button to stop the pump. 6, tour inspection should pay attention to: 1) Check the pump for liquid. 2) Check the lubrication, see the lubricant level is appropriate. 3) Check the cooling water conditions, water pressure requirements within the specified range. 4) Check and adjust the packing leakage, the amount of leakage is within the specified range, packing box temperature shall not exceed 70 â„ƒ. 5) The instructions of the instrument is normal. 6) Check the ministries pipeline valve is missing, with special attention to the intake pipe is not allowed to intake, so as not to affect the pump to work properly. 7) sliding bearing temperature shall not exceed 70 â„ƒ, rolling bearing temperature shall not exceed 80 â„ƒ. 8) Check pump vibration is not exceeded. 9) The flowmeter put into operation, observe its flow.

CEP Elevator Products specializes in custom elevator control modernization, ranging from simple updating of controls, cab and hall fixtures, to extensive replacement of all your existing elevator equipment. Elevator modernizations keep older buildings competitive with newer buildings, and typically provide a good financial return on your building as well as improving your elevators safety, reliability and performance. Depending on the age and condition of your elevator equipment, the extent of the modernization may vary. We can provide you with a free survey of your current equipment, and provide detailed information regarding the range of options for your upgrade. In addition to increasing the reliability and performance of your elevator, We will bring your elevator equipment up to current codes.

We only uses the best available equipment when performing modernizations. All modernizations begin with non-proprietary control systems and equipment which will enable you to use any qualified elevator service company of your choice to maintain your equipment in the future. Many large, international companies will only install their own proprietary controls and equipment which make it virtually impossible for building owners to change service companies down the road, regardless of the quality of service. This not only locks the building owner to one service company for the life of the equipment, it can also be costly in higher repair and maintenance costs.

After performing modernizations for over two decades, We have the experience and expertise to select the best individual components for your elevator. Many companies try to save money by cutting corners and using lower quality components; however we believe that the slightly higher price of the best components is well worth the cost to ensure that you not only get the look you expect, but also the performance and reliability for many years to come.
