What are the requirements for the maintenance and repair of the heavy oil burner oil pump? The heavy oil burner oil pump is a device for conveying oil or other liquids. It has high efficiency and can be directly connected with a high speed motor. The structure is simple, the body is light and easy to adjust. It is widely used in industrial and agricultural production and daily life.
When heavy oil coal tar pump is in operation, various failures may occur. Now, the possible causes and treatment methods may be introduced as follows.
1. The gear pump does not produce oil when it is started.
1 Not oiled or not filled with oil before starting. The pump should be stopped to refill the oil;
2 The oil absorption height is too large. Should reduce the oil absorption height, no more than 6 meters;
3 The oil suction pipe leaks or has air bubbles, and the oil suction pipe should be inspected to eliminate the air leakage;
4 oil faucet blocked, should clean the oil faucet;
5 revolutions are too low, check the power situation.
2. After starting, the oil pump discharge is small.
1 The impeller inlet is blocked by debris, the impeller is damaged or blocked; check the first section of the pump, clean up debris or replace the impeller;
2 The oil faucet is partially blocked; inspection and cleaning;
3 The oil suction pipe joint is not tight; check the joint to the mouth, tighten or change the pad;
4 The ribs of the impeller wear and the seal of the ring ring is excessively worn; after the inspection is confirmed, the ring seal is replaced;
5 trays leaked; replace the tray.
3. The oil faucet suddenly drops oil.
1 The oil tap is exposed to the oil surface; stop the pump.
2 The oil faucet is blocked; stop pump cleaning.
4, motor power "target=_blank> machine current is too large.
1 At the time of starting, the oil drain gate is closed at the end; pay attention when starting.
2 The balance ring plate is too inclined or the parts are stuck; check the inside and fix the abnormal parts.
3 The rotating part is not adjusted correctly, and the striking direction is too large to make the impeller against the ring; first push the impeller rotor to the apex of the oil inlet side, and check according to the scribe line.
4 pairs of wheels are not properly engaged or the apron is too tight; correct processing.
5, the oil pipe is too much oil to run high pressure oil.
1The balance between the balance disc sleeve and the string oil sleeve is enlarged; check the treatment and replace one of the parts if necessary.
2 The rubber balance ring is not properly assembled, and is not pressed by the bracket or the tightening ring. No rubber cord is added under the tightening ring; the bracket is removed and the balance ring is reassembled.
6. The pump has vibration during operation. Products produced by Botou Taibang Pump & Valve Manufacturing Co., Ltd. 1 Gear pump and motor center are not right; check and adjust.
2 The tubing is fixed incorrectly; check the adjustment.
3 bracket bearing clearance is large; check and adjust.
4-axis bending; overhaul, replace the new shaft.
5 impeller or balance disc skew; overhaul.
6 The grounding screw is loose and the foundation is not tightened; tighten the ankle bolt or study to solve the basic problem.
7, the bearing is hot.
1 The oil is not clean or the oil is insufficient; clean the bearings, change the oil or refuel.
2 Oil ring does not turn or is not flexible; check and handle.
3 bushing clearance is too small; adjust properly (pad or scraper).
8, the plate through the fever. The pan is too tight or not soaked; re-adjust or replace.
9, the balance plate is hot. The spent oil pipe is too dirty or the valve on the pipe is not open; clean the valve.
10. The gear pump housing is hot. When the gate is closed or there is no oil, the oil pump working time is too long; stop the pump to cool, and then pay attention when starting.
