How to Maintain and Repair of Multi-purpose DS Sand Suction Pump

DS sand suction pump is the kind of heavy duty sand pumping machine designed by OCEAN Pump to provide continuous transport of highly abrasive sand or slurries containing large particles with high flow, excellent efficiency, low maintenance and ownership costs.
Mr. Huang has a sand field, he want to use small stone and gravel to make sand, because the government has strict control over the river sand pumping. The sand produced during the stone and gravel crushing process contains more mud, and a large amount of muddy water is generated during the cleaning process. It is necessary to solidify the mud into a mud block by a filter press to facilitate handling. Because the pressure required for the feed is large, so Mr. Huang purchased two multi-purpose DS sand suction pump for the filter press from OCEAN Pump.

Troubleshooting of Multi-purpose DS Sand Suction Pump

The multi-purpose DS sand suction pump was installed on site and the effect was good. The mud began to form in about 10 minutes. After using for a period of time, the on-site master reflected the abnormal noise of the bearing, the pressure at the inlet was reduced, and the discharge time was extended. After receiving feedback from the on-site staff, OCEAN Pump arranged engineers to go to the site to repair the DS sand suction pump. Upon arrival at the scene, our staff conducted an overhaul of the following problems.

1. The multi-purpose DS sand suction pump was not on the horizontal line with the pulley of the motor, and the distance of the motor end pulley protruded outward by half of the sheave. At the same time, the DS sand suction pump bearing chamber had abnormal noise. The engineers guessed that the bearing might be damaged due to the force deviation caused by long-term disagreement.
2. The pressure at the feed port was reduced, indicating that the lift of the DS sand suction pump was reduced. The motor used in the field is the second-hand motor purchased by the customer. Our engineers used the speed measuring instrument to detect the lower motor speed. The rated speed of the 4-pole motor is 1470 rpm, but the display was only about 1300 rpm. The motor speed was low, so that the speed transmitted to the DS sand suction pump was not up to the rated speed, so the engineers recommended to increase the motor pulley by one specification. The original motor pulley was a C-type 4 slot with an outer diameter of 240 mm. The engineers recommended to use a pulley with an outer diameter of 260 mm.
3. The engineers checked the installation pipeline of the DS sand suction pump and found that the inlet pipe was only fitted on the joint, no fastening with clips. This method could easily lead to air intake of sand pump. At the same time, the packing had not been replaced for a long time, and there was a phenomenon of mud leakage. Various reasons caused the air intake of the sand suction pump, and the pressure did not meet the requirements. After finding the causes, the engineers began to transform the unreasonable places.
   
   
   
   
   
   
   

How to maintain and repair the Multi-purpose DS Sand Suction Pump

1. After OCEAN Pump engineers disassembled the bearing chamber of the multi-purpose DS sand suction pump, it was found that the balls of one bearing were damaged. Therefore, according to the model requirements, the on-site worker went out to buy.
2. At the same time, the engineers replaced the pulley with the outer diameter of 260 mm.
3. Reinforce the pipe at the entrance, and seal the interface with a film of grease to prevent air intake.
4. Because the engineers brought a box of packing in advance, they directly replaced the packing that has been worn out.

After all faults have been eliminated, our engineers installed the DS sand suction pump body and started up. There was no mud leakage at the place of the packing, and no abnormal noise in the bearing chamber. The slurry in the tank was quickly pumped into the filter press, and the effect was very obvious. During the maintenance process, our engineers patiently explained to the field staff the steps of replacing the parts and the methods for solving the problems, to ensure that the construction workers in the future work, such as replacing the packing and reinforcing the imported pipes, could handle the problems by themselves.

High Quality Slurry Pump was Delivered to Dongying for Building Yellow River Beach Area

High quality slurry pump, also known as sand pump and sediment pump, is an impurity pump that extracts the medium such as mud, fine sand, tailing slag and transports them over long distances. The Ocean brand high quality slurry pump is precisely cast with high wear resistant alloy material. High quality slurry pump is suitable for marine suction, sand pumping, reclamation, construction of docks,  , metallurgical transportation of tailing, river dredging and other industries, and it can also be used in electric power plant, etc.

Selection Procession of High Quality Slurry Pump

One customer from Dongying was using a DS 250-75 slurry pump produced by other supplier, supporting 250 KW motor. Inlet diameter of the  slurry pump is 10 inch / 250 mm, outlet diameter is 8 inch / 200 mm, discharge distance for 5 km. In the using period, the customer found that the slurry pump impeller wore quickly and had many cracks. It was also leaking and could not be used anymore.
On December 23, 2018, the customer contacted our company. Through communication, we found that the slurry pump type labeling parameters were incorrect. The actual parameters of the slurry pump type are much smaller than the marked parameters (Flow capacity is 1100 m³/h , Pump head is 50 m), there are problems in processing and assembly accuracy, especially there is no dynamic balance on impeller, this causes the impeller and the rear guard are easily attached together, which exacerbates the friction and the damage is relatively fast.
At that time, it was winter and the temperature was below zero, stopping the pump for a long time would cause the pipeline to freeze, this led to damage easily and reduced the service life of the pipeline. Our engineers suggested the customer reducing the frequency first in order to reduce the speed of the sand pump. The slurry pump only pumped water to ensure that the water in the pipe flowed. On the other hand, the assembly workshop of OCEAN Pump immediately assembled a 12-inch high quality slurry pump (DS 300-75) and the supporting base. Because the sand pump machine belongs to double pump casing series, it requires pressure and water leakage test. The test ensures that the inner pump casing, the front and rear guard plates are well sealed and leak-free. After overtime work, the commissioning was completed at 10:00 pm on December 23, 2018. The high quality slurry pump would arrive at the construction site at 8:00 on the 24th.

12 inch High Quality Slurry Pump (DS 300-75) Performance Parameters

Flow capacity	1100 m³/h
Head	50 m
Power	250 kw
Speed	730 rpm
Pump inlet	300 mm / 12 inch
Pump outlet	250 mm / 10 inch

On-site Installation and Commissioning for High Quality Slurry Pump

Our sales manager and after-sales installation engineers drove to the customer’s working  ite at 3 am on December 24, 2018, arrived at the site at 7:30, and started to install the sand pump.

1. Stop the high quality slurry pump and booster sand pump on board and discharge the water in the pipeline.
2. Temporarily raise the inlet pipe and the discharge pipe of the booster sand pump to ensure no water flow and save drainage time.
3. Remove the original slurry pump DS 250-75, and hoist the original 250 KW motor to the 12 inch high quality slurry pump installation base of our company, and start to adjust the concentration of the motor and mud pump and fix it.
4. Because the original pump type inlet is 250 mm and the outlet is 200 mm, and the new high quality slurry pump type inlet is 300 mm and the outlet is 250 mm. The imported and exported reducer tube is installed at the original pipeline.
5. Install a new high quality slurry pump DS 300-75 as a whole, and debug the steering and connecting pipes. The customer’s previous slurry pump does not have an outlet vent valve installed. According to the site conditions, an exhaust valve is installed to facilitate air removal and reduce Cavitation of the slurry pump.
6. Start the high quality slurry pump and booster sand pump for discharging on the dredger respectively, and adjust the power frequency of the booster sand pump according to the outlet flow to achieve the best relay condition.The whole modification process was very smooth. The customer thanked our company for actively cooperating, avoided further losses such as freezing on the pipeline, and learned the matters needing to pay attention to the high quality slurry pump through the modification process. The customer lamented that it is necessary to look for the brand when purchasing the slurry pump. Look for the manufacturers, remember that the price is low, find some personal pump companies.
