BM cycloidal hydraulic motor It is widely used in agriculture, animal husbandry, forestry, fruit industry and aquaculture, and has become an irreplaceable important part. However, it has always encountered various difficulties in daily use. Today I'm going to tell you about BM Cycloid hydraulic motor There are three specific solutions for finding exceptions. Those who are interested in finding exceptions can pay attention to the original text.

1、 Leakage

Cause: The port plate (port hole) is damaged or injured, and the plug hole and plunger are damaged, resulting in poor tightness between the high-pressure and low-pressure chambers. The working chamber can not cause high pressure, resulting in insufficient residual oil.

Solution: Check the BM cycloid Hydraulic motor If the oil distribution shaft or engine oil pan hole edge surface is scratched, remove it first, and replace it if it is serious; If there are troweling and groove excavation when checking the mating surface of plunger and plug hole, grind and polish the mating surface and install another grinding after polishing, and replace it if it is serious.

2、 Grab

Causes: unstable leakage, damage to the fixed support of the motor, accurate positioning of the roller bearing, resulting in transformation, parts damage, serious air pollution of the product oil wholesale, and the wrong phase angle of the flow distribution shaft and guide rail slope, resulting in strictly prohibited oil distribution, and inconsistent forward and reverse transmission ratios.

Solution: Clean or replace the oil distribution shaft or engine oil pan. If the motor fixed support is damaged, the roller bearing is positioned accurately, causing changes or parts are damaged, replace and readjust the roller bearing for accurate positioning.

3、 The motor rotor is stuck

Cause: The clearance between the plunger and the plug hole, the motor rotor hole and the port shaft is enlarged, and the debris in the gear oil enters the motor together with the patellar pressure oil, blocking the motor.

Solution: melt the BM cycloid hydraulic motor, remove the parts, and replace the damaged parts; If the clearance between the port pair and the plunger pair is incorrect, they should also be replaced; Replace the gear oil if necessary.
