Instructions for safe maintenance of electric pumping pump 1. In addition to complying with the instructions, the relevant provisions of GB3883. 1-83 "Technical Regulations for Safety Management, Inspection and Maintenance of Hand-held Power Tools".
Instructions for safe maintenance of electric pump 1. In addition to complying with the instructions, the relevant provisions of GB3883. 1-83 "Technical Regulations for Safety Management, Inspection and Maintenance of Hand-held Power Tools".
2. The rated value of the electric pumping pump product within the voltage range is ±10%.
3. The electric pump should avoid the electric level and the water and oil in the place where the electric level is installed. When using the pump, do not damage the electric level and avoid contact between the oil, water and electrical parts such as the motor switch.
4. In case of sudden start, the switch should be “off†(ie pressed) before the power is turned on.
5, electric pump does not abuse the power cord, do not allow the power cord to be lengthened or exchanged, can not pull the power cord to rub, cut and crushed.
6, the pump is explosion-proof type, when replacing the brush or repair, pay special attention to the explosion-proof surface of the explosion-proof parts can not cause damage to the hair. When repairing or replacing the brush, turn on the motor to clean the inner cavity toner, oil rust, etc.
7. Correct use of the hand, the pump power cord has no plug at one end, and the user chooses the appropriate plug. There are two sides and three points.
A. For plugs and sockets that must comply with the explosion-proof regulations for plugs and sockets that are explosive and flammable, set them in a normal place away from explosive and flammable sites. A 220V5A three-pin plug can be used, one of which is a grounding foot.
B. No matter what kind of plug is used, it must be grounded reliably. The yellow-green core wire at one end of the power cable is the grounding wire. When the connection is properly, check whether the metal casing of the pump and the contact pin are electrically connected. The resistance should not be greater than 1. Mother of Europe.
8. Prohibited places: Can not be used in special environments such as wet, wind and snow and corrosive gases.
Electric pump instruction instructions:
1. The electric pump uses the specified voltage: the line voltage does not exceed ±10% of the voltage specified on the pumping pump nameplate.
2. After the electric pump is unpacked, assemble it according to the structure diagram, connect the motor (1) and connect the mobile phone (2) so that the pump body and the motor are integrated (3) Connect the water wheel tube
3. Before using the electric pump, check that the external parts of the parts are in good condition before they can be used.
4. The electric pump should not be operated at idle. When using, the pumping is completed, that is, the pump is stopped, otherwise the bearing of the impeller seal will be accelerated. It is also possible to wear the pump tube because the pump motor has a no-load speed of 10,000 rpm.
5. Change the brush in time. When the brush is worn and will not be used, it must be replaced in time (2 brushes are exchanged at the same time). Otherwise, the contact between the brush and the commutator will cause ring damage, damage the commutator, and severely punish. Burn the armature.
6. It should not be used under the following conditions. If the insulation damage is found during the use, the power cable sheath is broken, the plug and socket are cracked or the contact is bad, and the operation is interrupted. When the motor is damaged, the motor casing is operated. Repairs should be made immediately. Do not use until it is repaired.
7. To prevent overload, when using, if the speed is abnormal or reduced, it should be stopped to check if there is any debris stuck in the impeller or the motor is faulty. The electric pump must cut off the power immediately when braking.
8, use tools to cherish all pumping pumps should be careful to avoid shock.
Electric pump maintenance
1. The electric pump is operated at high speed, and the grease is easy to volatilize. Therefore, the lubrication at the bearing must be kept clean and pay attention to replacement.
2. The electric pump should be inspected and repaired frequently. Check the power cord: whether the inner wiring, plug, switch is good, the insulation resistance is normal, the brush tail seat is loose, the commutator and the brush are in good contact, and the armature is wound. Whether the stage-expanded stator windings are suitable for interrupting the road, whether the bearings and rotating parts are damaged, and so on.
3. Each part should be preserved when disassembling the pump. Pay special attention to the explosion-proof surface of the explosion-proof parts. The insulation should not be damaged, including the insulating gasket and casing. If it is damaged, the new identical parts must be replaced. Do not use substitute materials that are lower than the performance of raw materials or parts that do not conform to the original specifications. All parts should be installed in the original position and should not be missed.
4. For electric pumping pumps that have not been used for a long time or used in humid environments, the insulation resistance of the windings must be measured with a 500 volt megger before use. If the insulation resistance between the winding and the motor casing is less than 7 megohms, the winding must be dried.
5. The electric pump should be placed in an environment that is dry, clean and free of corrosive gases.

PDC Cutters consist of diamond grit and tungsten carbide substrate, work layer & tungsten carbide part is used mesh connect method to make it stronger. it will combines advantage of both diamond and tungsten carbide and features as high abrasion resistant, high impact resistant and high thermal stable.
PDC Cutters are widely applied to oil/ gas drilling, geological exploration, coal mining and many other drilling and milling applications, toolng as PDC drill bits, such as steel PDC drill bits, Matrix PDC drill bits for oil and gas drilling and mining, Chain saw for marble and limestone quarry.
