The school bus subsidy for redemption implements the purchase price limit. The subsidy pricing standard is divided into three grades: the maximum price of 45-56 seats is not more than 400,000 yuan; the maximum price of 20-45 seats is not more than 300,000 yuan; The maximum price limit does not exceed 200,000 yuan.
The subsidy ratio is linked to the update time (subject to the purchase invoice date). If it is updated before December 31, 2014, it will be subsidized within 20% of the body price within the limit price; January 1st - June 30th, 2015 will be updated. In the limit price, it will be subsidized according to 10% of the body price; if it is updated from July 1st to December 31st, 2015, it will be subsidized according to 5% of the body price within the limit price. The subsidy funds are financed by the municipal finance and district (new district) finances by 50% each.
By-pass assembly has two positions; by-pass and close. It is in by-pass position during trip operation, and circulates mud fluid in the drill string into the annular space by-passing the idle motor, so that no mud may spray out onto the platform during the trip operation. When mud flow rate and pressure reach the setting value, the valve stem moves down and closes the valve. Meanwhile, mud stream flows through the motor, and converts the pressure energy into mechanical energy. As mud flow rate is too low, or mud pump stops, and as the pressure produced is not enough to overcome the spring force and the static friction force, the spring presses the stem upward, and by-pass is in open position. In general, the cross-over subs are used in deep well, large angle well, horizontal well or when hollow rotor is selected.
