32SB180J Spray Pump

Product details

32SB180J Spray pump is a kind of equipment especially matched for mud pump for oil drilling, with the function of flushing and cooling sleeve and pistons in the process of pump operation, as well as include the other situation for transportation mud.

The 32SB180J spray pump is the supply pump of the mud pump, which can be driven by a motor, so it is also called an electric spray pump.

Spray Pump Primary Structure
Spray pump is mainly composed of pump body, mechanical seal pump cover, mechanical seal, impeller, pump seat, etc. (see the figure below).
The main advantages of spray pump structure are: the main seal adopts mechanical seal, which ensures the operation without leakage. In addition, the pump has two modes of motor direct drive and pulley drive.

Spray Pump Faults and Troubleshooting Schedule

S/N	Fault	Cause	Troubleshooting
1	Excessive shaft power	1. Friction between impeller and pump base end face/mechanically real pump cover. 2. Pump operates under a condition where lift is much lower than that of the design point.	1. Adjust clearance between impeller and pump base end face/ mechanically real pump cover, to eliminate friction. 2. Check whether the service machine meets requirements; make opening of the drainage valve smaller, to make pump operates at the design point.
2	Reduced lift and flow	1.Large particles block suction pipe and impeller flow passage 2. Lower Speed of pump 3. Worn impeller 4.Excessive clearance between impeller and pump base end face, and increased leakage 5. Too small opening of inlet valve	1. Eliminate tamper. 2. Make pump operates at the rated speed. 3. Replace impeller. 4. Adjust clearance between impeller nd pump base end face. 5. Open inlet valve wider.
3	Bearing overheat	1. Too much or little lubricant 2. Foreign substances in oil 3. Worn bearing	1. Keep oil surface at position as specified by the oil level gauge. 2. Replace lubricant. 3. Replace bearing.
4	Vibration and abnormal noise during pump operation	1.Unbalanced wearing of impeller 2. Worn bearing 3. Loose connection 4. Cavitations of pump	1. Replace impeller. 2. Replace bearing. 3. Tighten all loose parts. 4. Improve suction condition, to prevent air into pump.
5	sealing serious leakage	1. Seriously worn shaft sleeve . 2.Foreign substances in mechanically real assembly. 3. Mechanical seal installation skew 4.Mechanical seal worn and ineffective.	1. Replace shaft sleeve. 2. Eliminate foreign substances and wash sealing parts. 3. Installation seal assembly again. 4. Replace mechanical seal.
