[0021] The technical solution of the present invention is further described below in conjunction with the accompanying drawings and specific implementation methods.
[0022] The speed-controllable solenoid valve motor of the present invention comprises a motor assembly 1, an oil inlet A port 2, an oil return B port 3, a rear cover 4, a two-position two-way solenoid valve 5, a throttle plug 6, a one-way relief valve 7 and an oil drain L port 8; the rear cover 4 is connected to the two-position two-way solenoid valve 5, the throttle plug 6 and the one-way relief valve 7; the housing of the motor assembly 1 is provided with an oil inlet A port 2 and an oil return B port 3; the rear cover 4 is provided with an oil drain L port 8.
[0023] The rear cover 4 of the present invention is provided with a solenoid valve jack for installing a two-position two-way solenoid valve 5. The rear cover 4 is provided with a throttle plug jack for installing a throttle plug (6). The rear cover 4 is provided with a one-way overflow valve jack for installing a one-way overflow valve 7. The oil drain port L 8 is connected to the oil tank. The rear cover 4, the two-position two-way solenoid valve 5, the throttle plug 6, and the one-way overflow valve 7 constitute the rear cover assembly. The front cover of the motor assembly 1 has a support bearing and is directly connected to the rear cover assembly.
[0024] In actual operation, the one-way relief valve 7 prevents the motor from being overloaded. Since the high-pressure chamber is converted into a low-pressure chamber, and when the motor stops working, oil can be replenished from the oil return chamber through the one-way valve to prevent air suction and ensure that the motor will not be damaged due to lack of oil.
[0025] The present invention realizes the power on and off of the motor through the reversing of the two-position two-way solenoid valve 5, the throttling plug 6 controls the running speed of the motor, and the one-way relief valve 7 prevents the motor from being overloaded during actual operation. When in use, when the two-position two-way solenoid valve 5 is not powered on, the motor oil inlet A port 2 passes a fixed flow rate, the one-way relief valve is at the maximum pressure, and part of the hydraulic oil returns to the oil tank through the oil drain L port 8, so that the motor runs at a constant speed; when the two-position two-way solenoid valve 5 is powered on, the motor oil inlet A port 2 passes a fixed flow rate, and under the rated pressure, part of the hydraulic oil passes through the two-position two-way solenoid valve 5 to the throttling plug 6, and then flows to the oil drain L port 8 through the throttling hole and returns to the oil tank, so that the motor runs at a constant speed.
[0026] The present invention arranges hydraulic components in an integrated manner, has a compact installation space, utilizes the oil cavity inside the motor to reduce pipeline connections, and is easy to operate.
