The following is the first part of the daily operation and maintenance of slurry pumps： tart-up and shutdown：

Preparations Before Start-up：

Check whether the connecting bolts and foundation bolts of the pump are loose.

Check whether the piping connection is proper and whether the centers of the pump and the driver are aligned. For pumps handling high-temperature or low-temperature liquids, the expansion and contraction of the piping may cause shaft misalignment, seizure, etc. Therefore, flexible pipe joints, etc., should be used.

Direct coupling and alignment. For small-sized pumps handling normal-temperature liquids, there is no problem in aligning the pump and the motor when the pump is stopped. However, for large-sized pumps handling high-temperature liquids, there is a large difference in the shaft center during operation and stoppage. To achieve correct alignment, generally heat to the operating temperature or stop the pump after the operation and quickly re-align to ensure that the shaft centers of both rotating parts are the same and avoid vibration and pump seizure.

Clean the piping. Before operation, the piping must be cleaned first to remove foreign objects, welding slag, etc. from the piping. Do not let foreign objects or welding slag fall into the pump body. Install pressure gauges before and after the strainer in the suction pipe to monitor the clogging of the strainer during operation.

Barring. Remove the coupling before start-up, turn the rotor by hand to observe whether there are any abnormal phenomena, and conduct a separate test run of the motor to check whether its rotation direction is the same as that of the pump. By rotating the coupling by hand, it can be found whether there are foreign objects between the impeller and the casing inside the pump. The barring should be even in weight, and there should be no abnormal noise inside the pump.

Start the oil pump and check whether the bearing lubrication is good.

Priming the pump. Fill the pump chamber with liquid before start-up to discharge air, liquefied gas, and steam from the suction pipe and the pump body.

Start-up：

The idle operation must be avoided. At the same time, open the suction valve, and close the discharge valve and each discharge hole.

Open the cooling water supply valve for the bearings.

If the stuffing box has a water jacket, open the cooling water supply valve of the stuffing box.

If the pump handling high-temperature liquid has not reached the working temperature, open the preheating valve, and close this valve after the pump is preheated.

If the pump is equipped with a liquid-sealing device, open the valve of the liquid-sealing system.

If equipped with an overheating device, open the bypass valve of the self-circulation system.

Start the motor.

When the pump flow increases and overheating is no longer possible, close the valve of the self-circulation system.

If the pump must be started with the check valve closed and the outlet gate valve open, the start-up steps are basically the same as the above method, except that the outlet gate valve should be opened for a period of time before the motor is started.

Gradually open the discharge valve.

Shutdown：

Open the valve on the self-circulation system.

Close the discharge valve.

Stop the motor.

If it is necessary to maintain the working temperature of the pump, open the preheating valve.

Close the cooling water supply valves of the bearings and the stuffing box.

If liquid-sealing is not required during the shutdown, close the liquid-sealing valve.

If it is a special pump device requirement or when the pump is opened for inspection, close the suction valve, and open the vent hole and various discharge holes.

Usually, the start-up and shutdown steps specified for turbine-driven pumps are basically the same as those for motor-driven pumps. Turbines have discharge valves, various drain holes, and sealing devices, which must be opened or closed before and after operation. In addition, turbines generally require preheating before start-up. Some turbines in the system are required to be started at any time, so barring operation is required. Therefore, the operator should operate according to the relevant regulations on the start-up and shutdown steps of the turbine provided by the turbine manufacturer.

Maintenance During Shutdown For standby pumps at the chemical plant site, when the in-use pump fails, they should be able to be switched over in time and put into normal operation to ensure that the chemical production process is not interrupted. This requires the maintenance of the standby pumps to keep them in good condition during the standby and shutdown period. Especially for standby pumps with interlock and automatic switching, their inlet and outlet valves are open, and the pumps are filled with the medium to be transported. As long as the driver rotates, they can start working immediately.

For standby pumps during the shutdown period, the quality and quantity of the lubricant should be checked frequently. The pump body and the medium inside the pump that needs to be heated and insulated should be heated and insulated. To prevent the rotor from bending due to its own weight and to prevent the shaft from adhering to the bearings and causing start-up difficulties, the standby pumps should be barring regularly.

For pumps that have been shut down for a long time, open the plugs on the pump body to drain the liquid inside the pump to avoid damage to the pump body due to cold weather. If necessary, open the pump body, clean the internal parts, and apply anti-rust oil. For pumps that have been shut down for a long time, whether they are on-site or in the warehouse, they should be barring regularly.

For details of the first part, please refer to the next blog post.

Lubrication: During the operation of a slurry pump, the possible intrusion of the conveyed medium, water, and other substances into the oil tank may affect the pump's normal operation. Therefore, it is necessary to check the quality and oil level of the lubricant frequently. The quality of the lubricant can be observed with the naked eye and analyzed by regular sampling. The amount of lubricating oil can be seen from the oil level mark.

For a new pump, the oil should be changed once after one week of operation. For a pump with replaced bearings during overhaul, the oil should also be changed. Because foreign substances enter the oil during the running-in of the new bearings and shafts, the oil must be changed. Thereafter, the oil should be changed once every quarter. The lubricating grease and lubricating oil used for chemical pumps should meet quality requirements. Tables 2-8 and 2-9 show the commonly used lubricating grease and lubricating oil for slurry pumps.

Vibration: During the operation of the pump, due to reasons such as poor quality of spare parts and maintenance, improper operation, or pipeline vibration, vibration often occurs. If the vibration exceeds the allowable value, the pump should be shut down for maintenance to prevent damage to the machine. Table 2-10 shows the allowable range of vibration values for slurry pumps.

Bearing temperature rise: During the operation of the pump, if the bearing temperature rises rapidly and after the temperature rise stabilizes, the bearing temperature is too high, which indicates that there are problems in the manufacturing or installation quality of the bearing; or the quality, quantity, or lubrication method of the bearing lubricating oil (grease) does not meet the requirements. If not dealt with in time, the bearing is in danger of being burned out. The allowable temperature for slurry pump bearings is <65°C for sliding bearings; and <70°C for rolling bearings. This allowable value refers to the allowable range of bearing temperature after running for a period of time. For a newly replaced bearing, at the initial stage of operation, the bearing temperature will rise relatively high. After running for a period of time, the temperature will drop somewhat and stabilize at a certain value.

The operating performance of slurry pump: During the operation of the pump, if there is no change in the liquid source and the opening degree of the valves on the inlet and outlet pipelines remains unchanged, but the flow rate or inlet and outlet pressure changes, it indicates that there is a fault in the pump or pipeline. The cause should be quickly identified and eliminated in time, otherwise, adverse consequences will be caused.

The size of the system resistance can be achieved by adjusting the opening degree of the inlet and outlet valves of the pump. For a determined pump system, when the outlet valve is fully opened, the system resistance is the smallest, and the corresponding flow rate is the largest, the head is the smallest, and the power is the largest. When the outlet valve is completely closed, the system resistance reaches a maximum value. At this time, the flow rate is zero, the head is the largest (a finite value), and the power is the smallest.

From this, the following points can be summarized:

When starting a slurry pump, in order to avoid overloading the prime mover, the outlet valve should be closed first and then opened slowly after the pump is started. In this way, it can avoid the superposition of the large starting load of the prime mover and the high power required by the pump when the outlet valve is fully opened, which may cause overloading of the prime mover.

As long as the pump chamber is filled with liquid (to avoid dry friction of the sealing ring, shaft seal, etc.), the slurry pump is allowed to operate for a short time when the outlet valve is closed. Except for the rapid temperature rise of the limited liquid in the pump chamber under the action of the rotating impeller, which has some adverse effects on the pump, there is no adverse effect on the prime mover. At this time, the load on the prime mover is the lightest.

During operation, any set of flow rates and heads within the performance range of the slurry pump can be obtained by adjusting the opening degree of the outlet valve. However, when the pump operates at the design operating point, its efficiency is the highest; the farther away from the design operating point, the lower the efficiency.

Unit sound: The sounds emitted by the pump during operation are some normal and some abnormal. For abnormal sounds, find out the cause and eliminate it in time. The following are roughly the reasons for the abnormal sounds of the pump.

Reasons on the fluid side: For example, insufficient inlet flow of the slurry pump causes cavitation and emits noise; air accumulation in the pump outlet pipeline causes water hammer and emits an impact sound.

Reasons on the mechanical side: The bearing quality does not meet the requirements or is damaged; the clearance between the moving and stationary parts of the pump is inappropriate, causing friction; shaft bending causes internal friction; parts are damaged and fall off; foreign objects fall into the pump, etc.
