The Fretsaw Motor is an improved specific motor for driving the oil pump. The main body comprises a motor, a front end cover and an input transmission shaft. The front end cover is provided with a stepped hole, the input transmission enters the front end cover, the shaft is hollow, the hole diameter of the shaft hole is together with the outer diameter of the output transmission shaft of the oil pump, and a key groove is arranged at the shaft head of the transmission shaft. The oil pump is divided into low-pressure and high-pressure: the high-pressure plunger oil pump makes the plunger move high and low in the plunger sleeve by relying on the camshaft in the pump, and the low-pressure oil provides the injector.
The reason for the low oil pressure of the Fretsaw Motor is that it is the primary component of the electric saw motor. Over time, the oil pump motor bearings and internal combustion engine will wear. Wear causes these parts to change size, which increases the clearance and allows a larger volume of oil flow, which can greatly reduce the pressure of kerosene over time. For example, the primary bearing of a worn engine can make the oil pressure output less than 20%. Replacing worn bearings can solve this problem.
Particles and oil pressure of Fretsaw Motor can also cause problems. After the oil flows into the oil pump, it returns to the oil pan and can take part of the debris. Debris can cause problems. For example, the oil small screen and the oil pump electromechanical itself. Kerosene holes are measured on a small screen of about 0.04 square inches. The size of the hole only connects large pieces, allowing many small pieces to flow through the screen. The hole on the screen is too large (relatively fragmented). Due to the abnormal oil at low temperature and slow engine speed, it needs to be closed and fixed freely. Even with these holes in the big screen, it can still become a blockage, resulting in low oil pressure. Through the small oil screen and oil filter, the debris can flow out of kerosene. This is a shift to minimize the number of engine debris flowing through the oil pump and oil filter.
